Hi Jack,  

Thanks for the suggestion. I maybe didn't explain my problem clearly enough.  

I cannot use sum as each row in the table would need to return a value for the indicator flag.

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
