Hi, I am a student at the University of Alberta, Canada and came across your support page while looking for some reference on 'ON UPDATE CASCADE'.The problem that I am facing is with the following statement, CREATE TABLE BLAH( blah1 VARCHAR(80) PRIMARY KEY, blah2 INT REFERENCES ANOTHER_BLAH(blah) ON DELETE SET NULL ON UPDATE CASCADE); I can enter the "ON DELETE CASCADE" OR "ON DELETE SET NULL", without any problems, but when I add "ON UPDATE CASCADE" on the next line, after one of the above, I get error messages, telling me that I am missing a right bracket. I am not missing a right bracket anywhere, and things work just fine when I take out the "ON UPDATE CASCADE" part. So I'm a bit perplexed as to what is wrong with ON UPDATE CASCADE ? I tried to find out more in the manual but didn't have much luck. Thanks in advance for your help, Vishal
