Note about upgrading: Doctrine uses static and runtime mechanisms to raise awareness about deprecated code.

Use of @deprecated docblock that is detected by IDEs (like PHPStorm) or Static Analysis tools (like Psalm, phpstan)
Use of our low-overhead runtime deprecation API, details: https://github.com/doctrine/deprecations/

Upgrade to 3.4

Deprecated `QueryBuilder` methods and constants.

The QueryBuilder::getState() method has been deprecated as the builder state is an internal concern.
Relying on the type of the query being built is deprecated by using QueryBuilder::getType() has been deprecated. If necessary, track the type of the query being built outside of the builder.

The following QueryBuilder constants related to the above methods have been deprecated:

SELECT,
DELETE,
UPDATE,
INSERT,
STATE_DIRTY,
STATE_CLEAN.

Marked `Connection::ARRAY_PARAM_OFFSET` as internal.

The Connection::ARRAY_PARAM_OFFSET constant has been marked as internal. It will be removed in 4.0.

Deprecated using NULL as prepared statement parameter type.

Omit the type or use Parameter::STRING instead.

Passing assets to the following AbstractPlatform methods and parameters has been deprecated:

The $table parameter of getDropTableSQL(),
The $table parameter of getDropTemporaryTableSQL(),
The $index and $table parameters of getDropIndexSQL(),
The $constraint and $table parameters of getDropConstraintSQL(),
The $foreignKey and $table parameters of getDropForeignKeySQL(),
The $sequence parameter of getDropSequenceSQL(),
The $table parameter of getCreateConstraintSQL(),
The $table parameter of getCreatePrimaryKeySQL(),
The $table parameter of getCreateForeignKeySQL().

Passing assets to the following AbstractSchemaManager methods and parameters has been deprecated:

The $index and $table parameters of dropIndex(),
The $table parameter of dropConstraint(),
The $foreignKey and $table parameters of dropForeignKey().

Pass a string representing the quoted asset name instead.

Marked `AbstractPlatform` methods as internal.

The following methods have been marked internal as they are not designed to be used from outside the platform classes:

getAdvancedForeignKeyOptionsSQL(),
getColumnCharsetDeclarationSQL(),
getColumnCollationDeclarationSQL(),
getColumnDeclarationSQL(),
getCommentOnColumnSQL(),
getDefaultValueDeclarationSQL(),
getForeignKeyDeclarationSQL(),
getForeignKeyReferentialActionSQL(),
getIndexDeclarationSQL(),
getInlineColumnCommentSQL(),
supportsColumnCollation(),
supportsCommentOnStatement(),
supportsInlineColumnComments(),
supportsPartialIndexes().

Deprecated internal `AbstractPlatform` methods.

The following methods have been deprecated as they do not represent any platform-level abstraction:

getCustomTypeDeclarationSQL(),
getIndexFieldDeclarationListSQL(),
getColumnsFieldDeclarationListSQL().

Deprecated `AbstractPlatform` methods.

usesSequenceEmulatedIdentityColumns() and getIdentitySequenceName() have been deprecated since the fact of emulation of identity columns and the underlying sequence name are internal platform-specific implementation details.
getDefaultSchemaName() has been deprecated since it's not used to implement any of the portable APIs.
supportsCreateDropDatabase() has been deprecated. Try calling AbstractSchemaManager::createDatabase and/or ::dropDatabase() to see if the corresponding operations are supported by the current database platform or implement conditional logic based on the platform class name.

Deprecated `SqlitePlatform::getTinyIntTypeDeclarationSQL()` and `::getMediumIntTypeDeclarationSQL()` methods.

The methods have been deprecated since they are implemented only by the SQLite platform, and the column types they implement are not portable across the rest of the supported platforms.

Use SqlitePlatform::getSmallIntTypeDeclarationSQL() and ::getIntegerTypeDeclarationSQL() respectively instead.

Deprecated `NULL` schema asset filter.

Not passing an argument to Configuration::setSchemaAssetsFilter() and passing NULL as the value of $callable has been deprecated. In order to disable filtering, pass a callable that always returns true.

Custom schema options have been deprecated since they effectively duplicate the functionality of platform options.

The following Column class properties and methods have been deprecated:

$_customSchemaOptions,
setCustomSchemaOption(),
hasCustomSchemaOption(),
getCustomSchemaOption(),
setCustomSchemaOptions(),
getCustomSchemaOptions().

Use platform options instead.

Deprecated `array` and `object` column types.

The array and object column types have been deprecated since they use PHP built-in serialization. Without additional configuration, which the API of these types doesn't allow, the usage of built-in serialization may lead to security issues.

The following classes and constants have been deprecated:

ArrayType,
ObjectType,
Types::ARRAY,
Types::OBJECT.

Use JSON for storing unstructured data.

Deprecated `Driver::getSchemaManager()`.

The Driver::getSchemaManager() method has been deprecated. Use AbstractPlatform::createSchemaManager() instead.

Deprecated `Visitor` interfaces and `visit()` methods on schema objects.

The following interfaces and classes have been deprecated:

Visitor,
NamespaceVisitor,
AbstractVisitor.

The following methods have been deprecated:

Schema::visit(),
Table::visit(),
Sequence::visit().

Instead of having schema objects call the visitor API, call the API of the schema objects.

Deprecated removal of namespaced assets from schema.

The RemoveNamespacedAssets schema visitor and the usage of namespaced database object names with the platforms that don't support them have been deprecated.

Deprecated the functionality of checking schema for the usage of reserved keywords.

The following components have been deprecated:

The dbal:reserved-words console command.
The ReservedWordsCommand and ReservedKeywordsValidator classes.
The KeywordList::getName() method.

Use the documentation on the used database platform(s) instead.

Deprecated `CreateSchemaSqlCollector` and `DropSchemaSqlCollector`.

The CreateSchemaSqlCollector and DropSchemaSqlCollector classes have been deprecated in favor of CreateSchemaObjectsSQLBuilder and DropSchemaObjectsSQLBuilder respectively.

Deprecated calling `AbstractPlatform::getCreateTableSQL()` with any of the `CREATE_INDEXES` and `CREATE_FOREIGNKEYS`

flags unset.

Not setting the CREATE_FOREIGNKEYS flag and unsetting the CREATE_INDEXES flag when calling AbstractPlatform::getCreateTableSQL() has been deprecated. The table should be always created with indexes. In order to build the statements that create multiple tables referencing each other via foreign keys, use AbstractPlatform::getCreateTablesSQL().

Deprecated `AbstractPlatform::supportsForeignKeyConstraints()`.

The AbstractPlatform::supportsForeignKeyConstraints() method has been deprecated. All platforms should support foreign key constraints.

Deprecated `AbstractPlatform::supportsForeignKeyConstraints()`.

Relying on the DBAL not generating DDL for foreign keys on MySQL engines other than InnoDB is deprecated. Define foreign key constraints only if they are necessary.

Deprecated `AbstractPlatform` methods exposing quote characters.

The AbstractPlatform::getStringLiteralQuoteCharacter() and ::getIdentifierQuoteCharacter() methods have been deprecated. Use ::quoteStringLiteral() and ::quoteIdentifier() to quote string literals and identifiers respectively.

Deprecated `AbstractSchemaManager::getDatabasePlatform()`

The AbstractSchemaManager::getDatabasePlatform() method has been deprecated. Use Connection::getDatabasePlatform() instead.

Deprecated passing date interval parameters as integer.

Passing date interval parameters to the following AbstractPlatform methods as integer has been deprecated:

the $quarters parameter in ::getDateAddQuartersExpression(),
the $quarters parameter in ::getDateSubQuartersExpression(),
the $years parameter in ::getDateAddYearsExpression(),
the $years parameter in ::getDateSubYearsExpression().

Use the strings representing numeric SQL literals instead (e.g. '1' instead of 1).

Deprecated transaction nesting without savepoints

Starting a transaction inside another transaction with Doctrine\DBAL\Connection::beginTransaction() without enabling transaction nesting with savepoints beforehand is deprecated.

Transaction nesting with savepoints can be enabled with $connection->setNestTransactionsWithSavepoints(true);

In case your platform does not support savepoints, you will have to rework your application logic so as to avoid nested transaction blocks.

Added runtime deprecations for the default string column length.

In addition to the formal deprecation introduced in DBAL 3.2, the library will now emit a deprecation message at runtime if the string or binary column length is omitted, but it's required by the target database platform.

Deprecated `AbstractPlatform::getVarcharTypeDeclarationSQL()`

The AbstractPlatform::getVarcharTypeDeclarationSQL() method has been deprecated. Use AbstractPlatform::getStringTypeDeclarationSQL() instead.

Deprecated `$database` parameter of `AbstractSchemaManager::list*()` methods

Passing $database to the following methods has been deprecated:

AbstractSchemaManager::listSequences(),
AbstractSchemaManager::listTableColumns(),
AbstractSchemaManager::listTableForeignKeys().

Only introspection of the current database will be supported in DBAL 4.0.

Deprecated `AbstractPlatform` schema introspection methods

The following schema introspection methods have been deprecated:

AbstractPlatform::getListTablesSQL(),
AbstractPlatform::getListTableColumnsSQL(),
AbstractPlatform::getListTableIndexesSQL(),
AbstractPlatform::getListTableForeignKeysSQL().

The queries used for schema introspection are an internal implementation detail of the DBAL.

Deprecated `collate` option for MySQL

This undocumented option is deprecated in favor of collation.

Deprecated `AbstractPlatform::getListTableConstraintsSQL()`

This method is unused by the DBAL since 2.0.

Deprecated `Type::getName()`

This will method is not useful for the DBAL anymore, and will be removed in 4.0. As a consequence, depending on the name of a type being json for jsonb to be used for the Postgres platform is deprecated in favor of extending Doctrine\DBAL\Types\JsonType.

Deprecated `AbstractPlatform::getColumnComment()`, `AbstractPlatform::getDoctrineTypeComment()`,

AbstractPlatform::hasNative*Type() and Type::requiresSQLCommentHint()

DBAL no longer needs column comments to ensure proper diffing. Note that all the methods should probably have been marked as internal as these comments were an implementation detail of the DBAL.

Upgrade to 3.3

Deprecated `Type::canRequireSQLConversion()`.

Consumers should call Type::convertToDatabaseValueSQL() and Type::convertToPHPValueSQL() regardless of the type.

Deprecated the `doctrine-dbal` binary.

The documentation explains how the console tools can be bootstrapped for standalone usage.

The method ConsoleRunner::printCliConfigTemplate() is deprecated because it was only useful in the context of the doctrine-dbal binary.

Deprecated the `Graphviz` visitor.

This class is not part of the database abstraction provided by the library and will be removed in DBAL 4.

Deprecated the `--depth` option of `RunSqlCommand`.

This option does not have any effect anymore and will be removed in DBAL 4.

Deprecated platform "commented type" API

Since Type::requiresSQLCommentTypeHint() already allows determining whether a type should result in SQL columns with a type hint in their comments, the following methods are deprecated:

AbstractPlatform::isCommentedDoctrineType()
AbstractPlatform::initializeCommentedDoctrineTypes()
AbstractPlatform::markDoctrineTypeCommented()

The protected property AbstractPlatform::$doctrineTypeComments is deprecated as well.

Deprecated support for IBM DB2 10.5 and older

The Connection::connect() method has been marked internal. It will be marked protected in DBAL 4.0.

Add `Connection::getNativeConnection()`

Driver and middleware connections need to implement a new method getNativeConnection() that gives access to the native database connection. Not doing so is deprecated.

Deprecate accessors for the native connection in favor of `getNativeConnection()`

The following methods have been deprecated:

Doctrine\DBAL\Driver\PDO\Connection::getWrappedConnection()
Doctrine\DBAL\Driver\PDO\SQLSrv\Connection::getWrappedConnection()
Doctrine\DBAL\Driver\Mysqli\Connection::getWrappedResourceHandle()

Call getNativeConnection() to access the underlying PDO or MySQLi connection.

Upgrade to 3.2

Minor BC Break: using cache keys with characters reserved by `psr/cache`

We have been working on phasing out doctrine/cache, and 3.2.0 allows to use psr/cache instead. To help calling our own internal APIs in a unified way, we also wrap doctrine/cache implementations with a psr/cache adapter. Using cache keys containing characters reserved by psr/cache will result in an exception. The characters are the following: {}()/\@.

Deprecated `SQLLogger` and its implementations.

The SQLLogger and its implementations DebugStack and LoggerChain have been deprecated. For logging purposes, use Doctrine\DBAL\Logging\Middleware instead. No replacement for DebugStack is provided.

The Configuration methods getSQLLogger() and setSQLLogger() have been deprecated as well.

Deprecated `SqliteSchemaManager::createDatabase()` and `dropDatabase()` methods.

PostgreSQL94Platform and PostgreSQL94Keywords. Use PostgreSQLPlatform and PostgreSQLKeywords instead.
SQLServer2012Platform and SQLServer2012Keywords. Use SQLServerPlatform and SQLServerKeywords instead.

Deprecated schema comparison APIs that don't account for the current database connection and the database platform

Instantiation of the Comparator class outside the DBAL is deprecated. Use SchemaManager::createComparator() to create the comparator specific to the current database connection and the database platform.
The Schema::getMigrateFromSql() and ::getMigrateToSql() methods are deprecated. Compare the schemas using the connection-aware comparator and produce the SQL by passing the resulting diff to the target platform.

Deprecated driver-level APIs that don't take the server version into account.

The ServerInfoAwareConnection and VersionAwarePlatformDriver interfaces are deprecated. In the next major version, all drivers and driver connections will be required to implement the APIs aware of the server version.

Deprecated `AbstractPlatform::prefersIdentityColumns()`.

Whether to use identity columns should be decided by the application developer. For example, based on the set of supported database platforms.

Deprecated `AbstractPlatform::getNowExpression()`.

Relying on dates generated by the database is deprecated. Generate dates within the application.

Deprecated reference from `ForeignKeyConstraint` to its local (referencing) `Table`.

Reference from ForeignKeyConstraint to its local (referencing) Table is deprecated as well as the following methods:

setLocalTable(),
getLocalTable(),
getLocalTableName().

When a foreign key is used as part of the Table definition, the table should be used directly. When a foreign key is used as part of another collection (e.g. SchemaDiff), the collection should store the reference to the key's referencing table separately.

Deprecated redundant `AbstractPlatform` methods.

The following methods implement simple SQL fragments that don't vary across supported platforms. The SQL fragments implemented by these methods should be used as is:

getSqlCommentStartString(),
getSqlCommentEndString(),

getIsNotNullExpression(),
getBetweenExpression(),
getAcosExpression(),
getSinExpression(),
getPiExpression(),
getCosExpression(),
getTemporaryTableSQL(),
getUniqueFieldDeclarationSQL().

The getListUsersSQL() method is not implemented by any of the supported platforms.

The following methods describe the features consistently implemented across all the supported platforms:

supportsIndexes(),
supportsAlterTable(),
supportsTransactions(),
supportsPrimaryConstraints(),
supportsViews(),
supportsLimitOffset().

All 3rd-party platform implementations must implement the support for these features as well.

The supportsGettingAffectedRows() method describes a driver-level feature and does not belong to the Platform API.

Deprecated `AbstractPlatform` methods that describe the default and the maximum column lengths.

Relying on the default and the maximum column lengths provided by the DBAL is deprecated. The following AbstractPlatform methods and their implementations in specific platforms have been deprecated:

getCharMaxLength(),
getVarcharDefaultLength(),
getVarcharMaxLength(),
getBinaryDefaultLength(),
getBinaryMaxLength().

If required by the target platform(s), the column length should be specified based on the application logic.

Deprecated static calls to `Comparator::compareSchemas($fromSchema, $toSchema)`

The usage of Comparator::compareSchemas($fromSchema, $toSchema) statically is deprecated in order to provide a more consistent API.

Deprecated `Comparator::compare($fromSchema, $toSchema)`

The usage of Comparator::compare($fromSchema, $toSchema) is deprecated and replaced by Comparator::compareSchemas($fromSchema, $toSchema) in order to clarify the purpose of the method.

Deprecated `Connection::lastInsertId($name)`

The usage of Connection::lastInsertId() with a sequence name is deprecated as unsafe in scenarios with multiple concurrent connections. If a newly inserted row needs to be referenced, it is recommended to generate its identifier explicitly prior to insertion.

Introduction of PSR-6 for result caching

Instead of relying on the deprecated doctrine/cache library, a PSR-6 cache can now be used for result caching. The usage of Doctrine Cache is deprecated in favor of PSR-6. The following methods related to Doctrine Cache have been replaced with PSR-6 counterparts:

class	old method	new method
`Configuration`	`setResultCacheImpl()`	`setResultCache()`
`Configuration`	`getResultCacheImpl()`	`getResultCache()`

Deprecated `AbstractPlatform::getReservedKeywordsClass()`

Instead of implementing getReservedKeywordsClass(), AbstractPlatform subclasses should implement createReservedKeywordsList().

Deprecated `ReservedWordsCommand::setKeywordListClass()`

The usage of ReservedWordsCommand::setKeywordListClass() has been deprecated. To add or replace a keyword list, use setKeywordList() instead.

Deprecated `$driverOptions` argument of `PDO\Statement::bindParam()` and `PDO\SQLSrv\Statement::bindParam()`

The usage of the $driverOptions argument of PDO\Statement::bindParam() and PDO\SQLSrv\Statement::bindParam() is deprecated. To define parameter binding type as ASCII, BINARY or BLOB, use the corresponding ParameterType::* constant.

Removed AbstractPlatform::getIdentityColumnNullInsertSQL().
Removed AbstractPlatform::fixSchemaElementName().
Removed Table::addUnnamedForeignKeyConstraint() and Table::addNamedForeignKeyConstraint().
Removed Table::renameColumn().
Removed SQLParserUtils::getPlaceholderPositions().
Removed LoggerChain::addLogger.
Removed AbstractSchemaManager::getFilterSchemaAssetsExpression(), Configuration::getFilterSchemaAssetsExpression() and Configuration::getFilterSchemaAssetsExpression().
SQLParserUtils::*_TOKEN constants made private.

BC BREAK changes the `Driver::connect()` signature

The method no longer accepts the $username, $password and $driverOptions arguments. The corresponding values are expected to be passed as the "user", "password" and "driver_options" keys of the $params argument respectively.

Removed `MasterSlaveConnection`

This class was deprecated in favor of PrimaryReadReplicaConnection

BC BREAK: Changes in the portability layer

The platform-specific portability constants (Portability\Connection::PORTABILITY_{PLATFORM}) were internal implementation details which are no longer relevant.
The Portability\Connection class no longer extends the DBAL Connection.
The Portability\Class class has been made final.

BC BREAK changes in fetching statement results

The Statement interface no longer extends ResultStatement.
The ResultStatement interface has been renamed to Result.
Instead of returning bool, Statement::execute() now returns a Result that should be used for fetching the result data and metadata.
The functionality previously available via Statement::closeCursor() is now available via Result::free(). The behavior of fetching data from a freed result is no longer portable. In this case, some drivers will return false while others may throw an exception.

Additional related changes:

The ArrayStatement and ResultCacheStatement classes from the Cache package have been renamed to ArrayResult and CachingResult respectively and marked @internal.

BC BREAK `Statement::rowCount()` is moved.

Statement::rowCount() has been moved to the ResultStatement interface where it belongs by definition.

Removed `FetchMode` and the corresponding methods

The FetchMode class and the setFetchMode() method of the Connection and Statement interfaces are removed.
The Statement::fetch() method is replaced with fetchNumeric(), fetchAssociative() and fetchOne().
The Statement::fetchAll() method is replaced with fetchAllNumeric(), fetchAllAssociative() and fechColumn().
The Statement::fetchColumn() method is replaced with fetchOne().
The Connection::fetchArray() and fetchAssoc() methods are replaced with fetchNumeric() and fetchAssociative() respectively.
The StatementIterator class is removed. The usage of a Statement object as Traversable is no longer possible. Use iterateNumeric(), iterateAssociative() and iterateColumn() instead.
Fetching data in mixed mode (former FetchMode::MIXED) is no longer possible.

BC BREAK: Dropped handling of one-based numeric arrays of parameters in `Statement::execute()`

The statement implementations no longer detect whether $params is a zero- or one-based array. A zero-based numeric array is expected.

BC BREAK `Statement::project()` has been removed

The Statement::project() method has been removed. Use ::executeQuery() and fetch the data from the statement using one of the Statement::fetch*() methods instead.

BC BREAK `::errorCode()` and `::errorInfo()` removed from `Connection` and `Statement` APIs

The error information is available in DriverException thrown in case of an error.

BC BREAK: Dropped support for `FetchMode::CUSTOM_OBJECT` and `::STANDARD_OBJECT`

Instead of fetching an object, fetch an array and map it to an object of the desired class.

BC BREAK: Dropped support for the `$columnIndex` argument in `ResultStatement::fetchColumn()`, other `ResultStatement::fetch*()` methods invoked with `FetchMode::COLUMN` and `Connection::fetchColumn()`.

In order to fetch a column with an index other than 0, use FetchMode::NUMERIC and the array element with the corresponding index.

BC BREAK: Removed `EchoSQLLogger`

EchoSQLLogger is no longer available as part of the package.

BC BREAK: Removed support for SQL Anywhere

The support for the SQL Anywhere database platform and the corresponding driver has been removed.

BC BREAK: Removed support for PostgreSQL 9.3 and older

DBAL now requires PostgreSQL 9.4 or newer, support for unmaintained versions has been dropped. If you are using any of the legacy versions, you have to upgrade to a newer PostgreSQL version (9.6+ is recommended).

The following classes have been removed:

Doctrine\DBAL\Platforms\PostgreSqlPlatform
Doctrine\DBAL\Platforms\PostgreSQL91Platform
Doctrine\DBAL\Platforms\PostgreSQL92Platform
Doctrine\DBAL\Platforms\Keywords\PostgreSQLKeywords
Doctrine\DBAL\Platforms\Keywords\PostgreSQL91Keywords
Doctrine\DBAL\Platforms\Keywords\PostgreSQL92Keywords

BC BREAK: Removed support for MariaDB 10.0 and older

DBAL now requires MariaDB 10.1 or newer, support for unmaintained versions has been dropped. If you are using any of the legacy versions, you have to upgrade to a newer MariaDB version (10.1+ is recommended).

BC BREAK: The `ServerInfoAwareConnection` interface now extends `Connection`

All implementations of the ServerInfoAwareConnection interface have to implement the methods defined in the Connection interface as well.

BC BREAK: `VersionAwarePlatformDriver` interface now extends `Driver`

All implementations of the VersionAwarePlatformDriver interface have to implement the methods defined in the Driver interface as well.

BC BREAK: Removed `MsSQLKeywords` class

The Doctrine\DBAL\Platforms\MsSQLKeywords class has been removed. Please use Doctrine\DBAL\Platforms\SQLServerPlatform instead.

BC BREAK: Removed PDO DB2 driver

This PDO-based IBM DB2 driver (built on top of pdo_ibm extension) has already been unsupported as of 2.5, it has been now removed.

The following class has been removed:

Doctrine\DBAL\Driver\PDOIbm\Driver

BC BREAK: Removed support for SQL Server 2008 and older

DBAL now requires SQL Server 2012 or newer, support for unmaintained versions has been dropped. If you are using any of the legacy versions, you have to upgrade to a newer SQL Server version.

The following classes have been removed:

Doctrine\DBAL\Platforms\SQLServerPlatform
Doctrine\DBAL\Platforms\SQLServer2005Platform
Doctrine\DBAL\Platforms\SQLServer2008Platform
Doctrine\DBAL\Platforms\Keywords\SQLServerKeywords
Doctrine\DBAL\Platforms\Keywords\SQLServer2005Keywords
Doctrine\DBAL\Platforms\Keywords\SQLServer2008Keywords

The AbstractSQLServerDriver class and its subclasses no longer implement the VersionAwarePlatformDriver interface.

BC BREAK: Removed `Doctrine\DBAL\Version`

The Doctrine\DBAL\Version class is no longer available: please refrain from checking the DBAL version at runtime.

BC BREAK User-provided `PDO` instance is no longer supported

In order to share the same PDO instances between DBAL and other components, initialize the connection in DBAL and access it using Connection::getWrappedConnection()->getWrappedConnection().

BC BREAK: the PDO symbols are no longer part of the DBAL API

The support of PDO::PARAM_*, PDO::FETCH_*, PDO::CASE_* and PDO::PARAM_INPUT_OUTPUT constants in the DBAL API is removed.
\Doctrine\DBAL\Driver\PDOConnection does not extend \PDO anymore. Please use \Doctrine\DBAL\Driver\PDOConnection::getWrappedConnection() to access the underlying PDO object.
\Doctrine\DBAL\Driver\PDOStatement does not extend \PDOStatement anymore.

Before:

use Doctrine\DBAL\Portability\Connection;

$params = array(
    'wrapperClass' => Connection::class,
    'fetch_case' => PDO::CASE_LOWER,
);

$stmt->bindValue(1, 1, PDO::PARAM_INT);
$stmt->fetchAll(PDO::FETCH_COLUMN);

After:

use Doctrine\DBAL\ColumnCase;
use Doctrine\DBAL\FetchMode;
use Doctrine\DBAL\ParameterType;
use Doctrine\DBAL\Portability\Connection;

$params = array(
    'wrapperClass' => Connection::class,
    'fetch_case' => ColumnCase::LOWER,
);

$stmt->bindValue(1, 1, ParameterType::INTEGER);
$stmt->fetchAll(FetchMode::COLUMN);

BC BREAK: Removed Drizzle support

The Drizzle project is abandoned and is therefore not supported by Doctrine DBAL anymore.

BC BREAK: Removed `dbal:import` CLI command

The dbal:import CLI command has been removed since it only worked with PDO-based drivers by relying on a non-documented behavior of the extension, and it was impossible to make it work with other drivers. Please use other database client applications for import, e.g.:

For MySQL and MariaDB: mysql [dbname] < data.sql.
For PostgreSQL: psql [dbname] < data.sql.
For SQLite: sqlite3 /path/to/file.db < data.sql.

BC BREAK: Changed signature of `ExceptionConverter::convert()`

Before:

public function convert(string $message, Doctrine\DBAL\Driver\Exception $exception): DriverException

After:

public function convert(Doctrine\DBAL\Driver\Exception $exception, ?Doctrine\DBAL\Query $query): DriverException

BC Break: The `DriverException` constructor is now internal

The constructor of Doctrine\DBAL\Exception\DriverException is now @internal.

BC Break: `Configuration`

all Configuration methods are now typed
Configuration::setSchemaAssetsFilter() now returns void
Configuration::$_attributes has been removed; use individual properties in subclasses instead
