Using IB_WISQL.

UPDATE FACTURE INNER JOIN CLIENTS ON FACTURE.NoTelephone =
CLIENT.NoTelephone SET FACTURE.NoClient = Client.NoClient;

And I get this:

ISC ERROR CODE:335544569

ISC ERROR MESSAGE:
Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, char 15
INNER

By the way this works in Access.

Any help would be appreciated.
