…cit IN clauses
- query() function now provides helpful error message for PIVOT statements without explicit IN clauses
- Previously showed confusing 'Expected a single SELECT statement' error, Now shows clear message: 'PIVOT statements without explicit IN clauses are not supported in query() function...'
- PIVOT statements with explicit IN clauses continue to work correctly
The issue occurred because PIVOT statements without explicit IN clauses create MultiStatement objects (containing CREATE TYPE + SELECT statements), but the query() function only accepted simple SelectStatement objects.
