Add up? I'm unclear about what you mean. You're going to get exactly one value per column per row. From your statement it appears that you mean you want 'N' for a return value when the columns contains 'One', 'Two', or 'Three' and you want 'Y' for 'Four'. Unless you're trying to mask your meaning I don't know why you're trying to transfer that meaning via numeric amounts.

If you mean something different, please explain. Otherwise

select decode(READERSHIP_OFTEN_SATURDAY, 'One','N','Two','N','Three','N','Four','Y','N') "Reader" from lee;

might be what you're trying to do.

Subject: Irritating problem

Chaps,

Been stuck on a little bit of sql.

Need to add up some columns with text values in them e.g 'One', 'Two' etc etc and see if the total is > 0.

Thought I had it working but its not

I am doing

select CASE WHEN (CASE WHEN READERSHIP_OFTEN_SATURDAY='One'

                       THEN 0.25 END)+


          (CASE WHEN READERSHIP_OFTEN_SATURDAY='Two' 

                       THEN 0.5 END)+


          (CASE WHEN READERSHIP_OFTEN_SATURDAY='Three' 

                       THEN 0.75 END)+


          (CASE WHEN READERSHIP_OFTEN_SATURDAY='Four' 

                       THEN 1 END) > 0 THEN 'Y' ELSE 'N' END AS Reader
                       FROM lee;

Data is as follows
Two values in table for READERSHIP_OFTEN_SATURDAY One Four

Both values are coming back as N when I would expect an Y.

Any help appreciated, its going to be staring me in the face but its late and Im tired.

TIA
Lee
