CASE Statement -- CASE - forum topic by jacksonprice

Hello --
 
I have a CHAR column which is returning '0' vs. NULL or blank.
I have tried several flavors of CASE, but cannot override the '0' with '       ', etc.
 
The closest I have come is to do a LIKE ('0') then '    ' and while that seems to work,  the results are returned in 2 columns -- the ORIGINAL column with the '0' and a CASE <expression> column with the blanks that I want -- I need single-column output so it can be fed to a compare program (before and after checking)...
 
what I'm doing is a SELECT columnA, CASE when columnA LIKE ('0') then '    ' end SAMPLE 1000; 
 
Any ideas?
 
Thanks so much.
