I'm using PHP 3.0.16 with iODBC(Openlink), and when I use the clause "group by" in an SQL instruction I receive an error message. I noted that when I use all the fields of the table in the "group by", I don't receive the message, but the result isn't what I want. I've tested the SQL instruction directely in the program odbctest of iODBC and it works perfectely.
