SQL_Mode commonly used value
| value | usefulness |
|---|---|
ONLY_FULL_GROUP_BY |
For Group By aggregate operations, if the column in select, does not appear in group by, then this SQL is illegal because the column is not in the group by clause |
| NO_AUTO_VALUE_ON_ZERO | This value affects the insertion of the growth column. Under the default settings, insert 0 or null represents the next self -growth value. If the user wants to insert 0 and the column is self -increased, then this option is useful. |
| STRICT_TRANS_TABLES | In this mode, if a value cannot be inserted into a transaction table, the current operation is interrupted, and there is no restriction on the non -transaction statement. |
| NO_ZERO_IN_DATE | In strict mode, the date and month are not allowed to be zero |
| NO_ZERO_DATE | When setting this value, the MySQL database does not allow insertion zero dates, and the zero date will throw an error instead of warning. |
| ERROR_FOR_DIVISION_BY_ZERO | In the INSERT or Update process, if the data is divided by zero, an error is generated instead of warning. If this mode is not given, then the data is returned to NULL when the data is removed from zero |
| NO_AUTO_CREATE_USER | Forbidden users of Grant to create a password to be empty |
| NO_ENGINE_SUBSTITUTION | If the required storage engine is disabled or not compiled, then the error is thrown. When this value is not set, use the default storage engine to replace it, and throw an exception |
| PIPES_AS_CONCAT | Will" |
| ANSI_QUOTES | After enabling Ansi_quotes, you cannot use double quotes to reference string, because it is explained as an identifiable symbol |
