Why isn't CASE supported for flow control in T-SQL ?
I have to do this ?:
IF @xyz = 1 THEN
EXEC dbo.PROC1
ELSE IF @xyz = 2 THEN
EXEC dbo.PROC2
ELSE
EXEC dbo.PROC3
END

Because T-SQL doesn't like to have flow control.

Don't forget to remove THEN, this isn't VB. 😛

Because T-SQL doesn't like to have flow control.

Why exactly ?

BTW: Thanks for that "THEN" but IMHO that should be optional.

Unlike Oracle where CASE can be used for control of flow, T-SQL does not have it overloaded in that manner. Why? I don't know, you'd actually need to go back Sybase Engineers to figure that one out.

You can use this type of conditional logic in stored procedures. Dunno if that's stating the obvious or not.
