Given the syntax error ... you are assuming that what you are seeing is the real statement. I'm not willing to make that assumption.

The OP has now stated: "I anonymised & simplified the query data incorrectly" so, given that it has been simplified, the real issue may bear no relationship to what has been posted.

To the OP. Anonymizing, ok, rename the tables and columns if you wish. But simplifying makes the exercise meaningless.
