Hi all,

Does Postgresql support DECODE() or IIF() functions like Oracle or SQLServer 
2000 does ??

PostgreSQL supports the standard CASE...WHEN... that replaces DECODE.
Oracle supports CASE WHEN too, but Oracle users usually use the 
Oracleisms counterparts.

I'm not familiar with IIF. What's it for?

P.S.: The PG docs have more info on CASE WHEN.

All in all, you're just another brick on the wall...

This is a M$-ism for in-line if, like ...
if true then A else B
iif(true,A,B)
