When I try to use the accordion module with a SQL backend. I get: 1038 [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or  are not allowed. Change the alias to a valid name.
