Glad to hear it's in the standard, but it's disappointing that it's not implemented in most RDBMS's. I tried the following in Oracle and got an error:

create table x( a integer, b integer);

select * from x where (a,b) < (1,2);

ORA-00920 Invalid relational operator

My db2 trial license expired, so I can't try it on that one ;-) . Received on Wed Feb 13 2002 - 17:58:02 CST
