in thread plperl RFC: (perl embedded in postgreSQL) An Oracle decode replacement

Actually "case x when bool then y when bool then z else zz end" is the standard compliant way to do oracle's decode

However I do like the "speed" and conciseness of the decode vs case. But as stated in the OP, I hacked this up to use for "work emulation". We use an ERP that uses Oracle 8i and the code base is littered with decodes, so to stop being asked to explain why my code doesn't "look like" the code from the ERP company's coders, I've just caved...

In my own code that doesn't "touch" the database directly (in a spreadsheet "solution" (ick..) or personal utility query) I use case.

Plus it was gobs of fun to write the plperlu script and find out how they set up the Safe container for plperl....

    Ah, yes, I was only talking about the nvl vs coalesce thing :)

    Maybe not that obvious since the rest of the post wasn't about that. Sorry about the confusion.
