Question

I have a column in a table with sample data as follows:

ServiceTypeIds
 7,1
 1,9 
 1
 9
 4
 7
 7 

In my Where clause I use the following to search on it:

WHERE (@ServiceTypes IS NULL 
   OR CHARINDEX(','+CAST(SEP.ServiceTypeIDs as VARCHAR(255))+','
              , ','+@ServiceTypes+',') > 0)))

If my param @ServieTypes equals ‘1,9’, then I get results, but when it’s @ServiceTypes = ‘1’ or just ‘9’, then I don’t recieve anything back. I’m stuck and tried the above.

Answer 1

I think you have your parameters reversed:

WHERE (@ServiceTypes IS NULL 
       OR CHARINDEX(','+CAST(@ServiceTypes as VARCHAR(255))+',',
                    ','+SEP.ServiceTypeIDs+',') > 0)))

This method works, but only when you are looking for one item (or are lucky and the two items happen to be in the same sequence).
