Re: request for sql3 compliance for the update command

Patrick,

No, they support the syntax:

update table set (col1, col2, col3) = ( val1, val2, val3 )

I have a customer with a rather large application which uses this
syntax, because they were using informix. There is also a rather
interesting 4GL project called aubit which is on sourceforge. They would
also like to see this supported for the same reasons.
