Query on blob col using CQL3

Anyone can suggest how to query on blob column via CQL3. I get  bad request error saying cannot parse data. I want to lookup on key column which is defined as blob.

But I am able to lookup data via opscenter data explorer.  Is there a conversion functions I need to use?

Re: Query on blob col using CQL3

why are you trying to view a blob with CQL3? and what kind of blob is it?

if the blob is an object, there's no way to view that in CQL3. You'd need
to do extra work like user defined types, but I don't know of anyone that's
actually using that.
