|Value for the MySQL
|Introduced in version:||1.17.0 (r68558)|
|Removed in version:||still in use|
|Allowed values:||string or null|
|Default value:||empty string|
|Other settings: Alphabetical | By function|
If this setting is not null, the MySQL server is sent the SQL query
SET sql_mode = "$wgSQLMode". See the MySQL documentation for more details.
The default is
null, which means that the query to set
sql_mode is not issued. This can be used to skip the setting for performance reasons and assume the database admin (DBA) has done his best job.
