For looking at the attached trace output, it looks like Oracle is deferring checking of the passed SQL until the getResultSet() call (which has been an important optimization for many years). However, this means that the SQL error is not detected as early as possible. We likely need to change the following code to save the PreparedStatement in a SqlStatementWrapper that is passed in, so that the caller can closed the prepared statement. Or something like that.

		final PreparedStatement st = prepareQueryStatement( sql, queryParameters, limitHandler, scroll, session );
		return new SqlStatementWrapper(
				st, getResultSet(
				st,
				queryParameters.getRowSelection(),
				limitHandler,
				queryParameters.hasAutoDiscoverScalarTypes(),
				session
		)
		);
