Hello,
who can I use a variable like the followig
set @MAG3 = '<> 0'
or
set @MAG3 = '= 0'
for the following where condition
where patindex('%;' + Mitarbeiter + ';%' , @MAG2) <> 0
I like to change the <> 0 Parameter but
where patindex('%;' + Mitarbeiter + ';%' , @MAG2) @MAG3
don`t work.
Thank for help.
Olaf

No, that's not going to work. Can you take a bit of time to explain the logic you are trying to achieve? There will be another way to achieve it, I'm sure.

Hello,

I have in my select a column called "Mitarbeiter". I like to search for Mitarbeiter in ('SB','MS','BE') or Mitarbeiter not in ('SB','MS','BE')

The 'IN' or 'NOT IN' I want to change via a variable. (For SQL Server Reports)

so I come to the patindex and the change between <>0 and =0

But how to change it?

There's a simple way to do this:

WHERE (@Var3 = 'IN' AND Mitarbeiter IN ('SB','MS','BE'))

OR (@Var3 = 'NOT IN' AND Mitarbeiter NOT IN ('SB','MS','BE'))

It's called a "Catch-all" query and has known limitations. Gail Shaw has a good account of those limitations here[/url].
