    The two branches are not identical btw. They differ also in the where mur=, ref=

    This article should be labelled "How to screw over your database by caching the worst execution plan or the day I decide to recompile my procedures every time".

    We don't know what the consultant was paid to do, so the WTF can't be on his side until we know more. Seems to me he went in to point the finger to some sore spots, and by the looks of it, he found them (and filled his report with some mumbo jumbo to keep the PHB happy.) The feature that sends this to the frontpage of this site is the sheer incompentence by the company to figure out the problems by themselves.

    Granted we do not know if the procedure is inside a transaction itself, but I don't see any transactions in the procedure. This leads me to ask if querying the orders table for the same key multiple times and taking a different attribute from each query ever leads to integrity problems in the application.

    The most simple variant I could come up with, while keeping it sane and readable:

    IF @origin IN (-2, -4, -5, -6, -7, -8, -9)
BEGIN
	SELECT @id = sender_id
			, @group = user_group
			, @file_ref = file_ref 
	FROM order 
	WHERE ref = @mur
	
	SELECT @ref = ref 
	FROM order 
	WHERE mur = @mur
END
ELSE 
	SELECT @id = sender_id
			, @group = user_group
			, @file_ref = file_ref
			, @ref = ref  
	FROM order 
	WHERE mur = @mur

    What are you all complaining about? At least, the database is not an Excel file.

    They who fail to understand SQL are condemned to be repeatedly on TDWTF.

    Does that mean TDWTF is a SQ-Hell? :D

    Ah, the good old "Why are you complaining about murder when I didn't piss on the grave" argument. Never gets old :-)

    You broke it! SELECT @ref = ref should be OUTSIDE the if statement, or in both the BEGIN and ELSE...

  • DJ Dizzy Spudplucker (unregistered) in reply to (not a)[email protected](or is it)

    Actually, I missed something ... that looks much nicer, by eliminating another SELECT that's not needed some of the time

    No ifs or buts, but there are some ands. (And handles @origin being null.)

    select @id = sender_id, @group = user_group, @file_ref = file_ref, @ref = ref from order where (@origin in (-2, -4, -5, -6, -7, -8, -9) and ref = @mur) or ((@origin is null or @origin not in (-2, -4, -5, -6, -7, -8, -9)) and mur = @mur)

    Addendum 2024-04-24 15:20: Apparently I need to learn what the formatting methods are for DailyWTF.

  • (nodebb)

    It's basically markdown but a very limited form of it (https://www.markdownguide.org/).

    The append comment feature mislabeled "Edit" is no help here either especially since the character limit includes those addendums. A "Preview" feature would be arguably more useful for a site that requires a lot of formatting due to the discussion topics often including source code and structural data.

    A preview is a much requested item.
