hello,
I need to join this 3 tables.
If I join only "ID Gara" and "Ragione Sociale" everything works but when I add "Codice Categoria Merceologica" the system give a circular references error.
Someone can help me to solve it? I need to join id gara - ragione sociale - codice cat. merceologica for my activities.
Thanks,
Marco
I would rename "Codice Categoria Merceologica". Either explicitly or through the QUALIFY statement.
