Features

This package allows additional configuration of features available within SQLite3 to be enabled or disabled by golang build constraints also known as build tags.

Click here for more information about build tags / constraints.

Usage

If you wish to build this library with additional extensions / features. Use the following command.

go build --tags "<FEATURE>"

For available features see the extension list. When using multiple build tags, all the different tags should be space delimted.

Example:

go build --tags "sqlite_icu sqlite_json1 sqlite_fts5 sqlite_secure_delete"

Feature / Extension List

Extension	Build Tag	Description
Additional Statistics	sqlite_stat4	This option adds additional logic to the ANALYZE command and to the query planner that can help SQLite to chose a better query plan under certain situations. The ANALYZE command is enhanced to collect histogram data from all columns of every index and store that data in the sqlite_stat4 table. The query planner will then use the histogram data to help it make better index choices. The downside of this compile-time option is that it violates the query planner stability guarantee making it more difficult to ensure consistent performance in mass-produced applications. SQLITE_ENABLE_STAT4 is an enhancement of SQLITE_ENABLE_STAT3. STAT3 only recorded histogram data for the left-most column of each index whereas the STAT4 enhancement records histogram data from all columns of each index. The SQLITE_ENABLE_STAT3 compile-time option is a no-op and is ignored if the SQLITE_ENABLE_STAT4 compile-time option is used
Allow URI Authority	sqlite_allow_uri_authority	URI filenames normally throws an error if the authority section is not either empty or "localhost". However, if SQLite is compiled with the SQLITE_ALLOW_URI_AUTHORITY compile-time option, then the URI is converted into a Uniform Naming Convention (UNC) filename and passed down to the underlying operating system that way
App Armor	sqlite_app_armor	When defined, this C-preprocessor macro activates extra code that attempts to detect misuse of the SQLite API, such as passing in NULL pointers to required parameters or using objects after they have been destroyed. App Armor is not available under Windows.
Disable Load Extensions	sqlite_omit_load_extension	Loading of external extensions is enabled by default. To disable extension loading add the build tag sqlite_omit_load_extension.
Foreign Keys	sqlite_foreign_keys	This macro determines whether enforcement of foreign key constraints is enabled or disabled by default for new database connections. Each database connection can always turn enforcement of foreign key constraints on and off and run-time using the foreign_keys pragma. Enforcement of foreign key constraints is normally off by default, but if this compile-time parameter is set to 1, enforcement of foreign key constraints will be on by default
Full Auto Vacuum	sqlite_vacuum_full	Set the default auto vacuum to full
Incremental Auto Vacuum	sqlite_vacuum_incr	Set the default auto vacuum to incremental
Full Text Search Engine	sqlite_fts5	When this option is defined in the amalgamation, versions 5 of the full-text search engine (fts5) is added to the build automatically
International Components for Unicode	sqlite_icu	This option causes the International Components for Unicode or "ICU" extension to SQLite to be added to the build
Introspect PRAGMAS	sqlite_introspect	This option adds some extra PRAGMA statements. PRAGMA function_list PRAGMA module_list PRAGMA pragma_list
JSON SQL Functions	sqlite_json	When this option is defined in the amalgamation, the JSON SQL functions are added to the build automatically
libsqlite3	libsqlite3	Use the system SQLite3 library
Pre-Update Hook	sqlite_preupdate_hook	Allows the registration of a Pre-Update Hook; the Pre-Update Hook cannot be used in conjunction with libsqlite3, because if linked to older version the required C functions are not present.
Secure Delete	sqlite_secure_delete	This compile-time option changes the default setting of the secure_delete pragma. When this option is not used, secure_delete defaults to off. When this option is present, secure_delete defaults to on. The secure_delete setting causes deleted content to be overwritten with zeros. There is a small performance penalty since additional I/O must occur. On the other hand, secure_delete can prevent fragments of sensitive information from lingering in unused parts of the database file after it has been deleted. See the documentation on the secure_delete pragma for additional information
Secure Delete (FAST)	sqlite_secure_delete_fast	For more information see PRAGMA secure_delete
Tracing / Debug	sqlite_trace	Activate trace functions
User Authentication	sqlite_userauth	SQLite User Authentication see User Authentication for more information.
Virtual Table	sqlite_vtable	SQLite Virtual Table for more information see SQLite VTab
