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
