SubPage filter by needs to be specific to table February 03, 2019, 09:53:50 PM This error comes up: Integrity constraint violation: 1052 Column 'ID_Veranstaltung' in order clause is ambiguous.When addng a subpage to a mainpage and trying to filter for a specific field, i need to be able to specify the tablename.Otherwise i cant join three or more tables with identical coloumn names and filter by one of these coloumns.Or simply allow a querybuilder for the filter.
