What SQL-Statement creates yii?

Created 8 years ago by Necip Necip, updated 8 years ago by Necip Necip. 0 comments

The usual way to find out what Yii has created for an SQL query is to mutilate the SQL in the sourcecode and call the program again so that the SQL statement with errors is displayed. Or you can use the SQL logger, which must be switched on and off each time and logs all SQL statements, which leads to an enormous slowdown in program execution and decelerates your workflow.
