I can beat that - I discovered a bug where new records were failing to be added.
After a number of false trails, I homed in on the following SQL user function:
ALTER function [dbo].[ufn_GetNextID](@IDTable as varchar(100), @IDColumn as varchar(100))
returns integer
as
begin
declare @NewID as integer
set @NewID=0
return @NewID
end

I don't see anything wrong there, what does "0" mean anyway?

I believe its the shape of my mouth every time I come across examples like this!

if(SomeThing == SomeOtherThing);

DoSomeThing;

This one has been sitting in the codebase for a couple of years...
At least it did SomeThing...

Which language? The C# compiler will give you a warning for that: "Possible mistaken empty statement".

Even C back in the old days gave you a warning for that.

Wich compiler ?
while (*dest++ = *source++);
is completely correct, isn't it ?
|
|
|
|

It's a warning, not an error, for that reason. This was back when I used Zortech's ANSI C compiler.

Actually, in this case the C# produces three useless wormings: both for the "while(...);" (an empty statment), "x=y" (an assigment instead of a comparison) and the "*" (an "unsafe" code), does it?

Thanks for the correction.
My example was - as a reply to the mention of C, of course a C code snippet,
and is the full working function body for strcpy().
Of course, it's unsafe - but lightning fast

Just in case you didn't get the joke there, he's making a funny about the compiler being witchcraft. The word you meant to use is 'which'.

They're not useless warnings, they're warning you that you did something unintended. Actually this wouldn't compile at all in C#, even with unsafe mode turned on, because the result type isn't boolean. It's a classic and well known piece of C code, and I think you only got a warning for the empty loop body (and if you did if(a = 3) by accident you were just screwed, hence writing if(3 == a) instead which is an error if you screw it up).

Right.

Does that even compile?

No, it doesn't. But that's just the bug: it doesn't compile!
[EDIT]
I'm sorry, I didn't see the semicolon after the if statement. That's the bug!
