Re: faster alternative to where clause in SQL

Ravi , I tried union with constants ,

TABLE A has DIM1, DIM2, DIM3, MEA1, MEA2

AND

TABLE B HAS DIM4, DIM5, DIM6, MEA3, MEA4

but I could not manage to get DIM`1, DIM2, DIM5, MEA1, MEA2, MEA4 into 1 single line

Can you give more insights , if i am able to do an union , its definitely less expensive than a join .
