Question

I can’t make a where clause on the IdCell column but i can do an “order by”.

SQL server say error on the column name

    select 
    *, (ISNULL(Table_Adresses.IdCellule, Table_Clients.IdCellule)) as IdCell
    from Table_Tickets 
    left join Table_Postes on Table_Postes.IdPoste = Table_Tickets.IdPoste
    left join Table_Adresses on Table_Adresses.IdAdresse = Table_Postes.IdAdressePhysique
    left join Table_Clients on Table_Clients.IdClient = Table_Tickets.IdClient
    where idtypeticket=2 and 
    isnull(bcloture,0)=0 and 
    IdCell =4 --problem here
    order by IdCell

Why can’t i make a where on IdCell ?

Thank you

You can’t use your aliased column in this way, you’ll need to do:

and (ISNULL(Table_Adresses.IdCellule, Table_Clients.IdCellule)) = 4
