The error "RETURN_GENERATOR operation not supported on select()" typically occurs in Python when you try to use a generator object in a query that requires a return value.

In SQL, a SELECT statement is used to retrieve data from a database table. When you use a generator in a SELECT query, you may encounter this error because a generator doesn't have a specific return value. Instead, a generator is used to produce a sequence of values that can be accessed one at a time.

To fix this error, you may need to modify your code to use a different data structure that can be used in a SELECT query or change the query itself to work with generator objects.
