Delete()+WHERE INissue on MySQL for #699.The direct cause was the implementation of
Delete(). When the query could haveWHERE IN, currently the query should be generated via SQLBuilder (specificallysqlx.In()insqlBuilder.compile()to expand?to match with the arguments.The root cause is the SQL syntax of MySQL. MySQL 5.7 does not support table alias for the
DELETEstatement, soAS table_aliascauses a syntax error. I guess theDelete()for MySQL has its own implementation for this reason. The syntax was changed in 8.0 so when 5.7 is fully EOSed, we can use the generic version here.fixes #699
