◆ OPTION_AUTO_IS_NULL

#define OPTION_AUTO_IS_NULL   (1ULL << 14)

◆ OPTION_AUTOCOMMIT

#define OPTION_AUTOCOMMIT   (1ULL << 8)

always the opposite of OPTION_NOT_AUTOCOMMIT except when in fix_autocommit()

◆ OPTION_BEGIN

#define OPTION_BEGIN   (1ULL << 20)

◆ OPTION_BIG_SELECTS

#define OPTION_BIG_SELECTS   (1ULL << 9)

◆ OPTION_BIN_LOG

#define OPTION_BIN_LOG   (1ULL << 18)

◆ OPTION_BUFFER_RESULT

#define OPTION_BUFFER_RESULT   (1ULL << 17)

◆ OPTION_DD_UPDATE_CONTEXT

#define OPTION_DD_UPDATE_CONTEXT   (1ULL << 38)

◆ OPTION_FOUND_COMMENT

#define OPTION_FOUND_COMMENT   (1ULL << 15)

◆ OPTION_LOG_OFF

#define OPTION_LOG_OFF   (1ULL << 10)

◆ OPTION_MASTER_SQL_ERROR

Is set in slave SQL thread when there was an error on master, which, when is not reproducible on slave (i.e.

the query succeeds on slave), is not terminal to the state of replication, and should be ignored. The slave SQL thread, however, needs to rollback the effects of the succeeded statement to keep replication consistent.

#define OPTION_NO_CONST_TABLES   (1ULL << 23)

◆ OPTION_NO_FOREIGN_KEY_CHECKS

#define OPTION_NO_FOREIGN_KEY_CHECKS   (1ULL << 26)

The following can be set when importing tables in a 'wrong order' to suppress foreign key checks.

◆ OPTION_NO_SUBQUERY_DURING_OPTIMIZATION

#define OPTION_NO_SUBQUERY_DURING_OPTIMIZATION   (1ULL << 39)

If this option is set, subqueries should not be evaluated during optimization, even if they are known to produce a constant result.

◆ OPTION_NOT_AUTOCOMMIT
