The IGNORE
option tells the server to ignore some common errors.
IGNORE
can be used with the following statements:
The logic used:
STRICT_TRANS_TABLES
, STRICT_ALL_TABLES
, NO_ZERO_IN_DATE
, NO_ZERO_DATE
are ignored. NULL
in a NOT NULL
field will insert 0 ( in a numerical field), 0000-00-00 ( in a date field) or an empty string ( in a character field). The following errors are ignored:

Ignored errors normally generate a warning.
A property of the IGNORE
clause consists in causing transactional engines and non-transactional engines (like XtraDB and Aria) to behave the same way. For example, normally a multi-row insert which tries to violate a UNIQUE
contraint is completely rolled back on XtraDB/InnoDB, but might be partially executed on Aria. With the IGNORE
clause, the statement will be partially executed in both engines.
Starting from MariaDB 5.5.28 duplicate key errors also generate warnings. The OLD_MODE
server variable can be used to prevent this.
