Could anyone tell me what pairwise and nonpairwise comparison are?
MCSE/MCDBA, OCP DBA 8i
Working on SCJP -> SCJD
Multiple Column Subqueries
A multiple column subquery returns more than one column. Column comparison in multiple column comparisons can be pairwise or nonpairwise.
I had this kind of question in my exam, but only guessed the meaning is corresponding multiple columns comparison, can't find any formal information from Oracle.
I have a ppt file about pairwise and nonpairwise. I can't post here. How can I give you?
Please send it to
