I don't even think you have to use the AS part -> this should work: > CREATE VIEW "FOO" ( > "MEMBERID", > "SURNAME", > "FIRSTNAME" > ) AS > select "MEMBER"."OID", > "MEMBER"."SURNAME", "MEMBER"."FIRSTNAME" > from "MEMBER"; But you do have to declare the column names in the part before the query expression. -- Martijn Tonies Database Workbench - the IBConsole alternative!
