Dear All,

I need your help for a quick question.

If I use "Select unique variable1, variable2, variable3" statement,
dose the "unique" work for only variable1, or work for all the three
variables, Variable1-3 ?

Thank you!

It gets you the combination of var1-3:

A A A
A A B
A A C
A B A
A B B
A B C
B A A
....
