[dba-SQLServer] If or Case or 'what'?

I will...

The guy I'm helping with this...just shared exactly what he is trying to 
do...so the next question is...is there a limit to the number of cases you 
can have in a single statement?

...or is there a better approach to what we are doing?  We have a table with 
all of the data created below(my first email)...then he wants to populate a 
category field with 1 of about 30 values...depending on the data in the 
records.  Then there is another field treated the same way...another 30 
Cases.  Is there a limit? and...  Case should be the way to go...right?

Thanks,

Mark
