Re: Return list by limit 1 which is NOT null
No, you will need to filter client side. Can you do it in a single row ?

Re: Return list by limit 1 which is NOT null
Thanks Aaron. How do I implement that in the row? Does row will not have any tombstones? Please let me know.

Re: Return list by limit 1 which is NOT null
Tombstoned rows are returned without any columns. Cheers - Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 25/01/2012, at 4:37 AM, Eric Martell wrote: Thanks Aaron.
