[Firebird-devel] Just added CASE,COALESCE,NULLIF -> Should IFF be added to ?

[Arno B. <fir...@ab...>]

Hi,

I've implemented COALESCE,CASE,NULLIF into FB2.
Because there are people asking for function IIF(<search condition>,<value
if true>,<value if false>) should this be added also.
Adding the IFF function is very easy because i already implemented
CASE....END (on the right way using blr_value_if as some people suggested
:-)
But IFF isn't an SQL-standard function that's the reason why i didn't add it
currently.

So ?
Suggestions ?
Good arguments why / why not ?
