You can pick up the InterBase 6 Language Reference here: http://www.ibphoenix.com/files/60LangRef.zip, and visit the section "SQL Statement and Function Reference :: ALTER TABLE". That's the basis. The document Thomas pointed you to contains the updates since Firebird was forked from the IB sources. Good luck, Paul Vinkenoog
