Subject Only know if BLOB text field has a value?
Author Hug
Is there a way, in StoredProcedure language, to know if a BLOB field (type
text) contains something?
It's to say: can I to find out if that field is null, without to fetch it?
I don't need the value.
Since I can't make a SELECT BLOB_FIELD FROM TABLE INTO :nothing
... how I can achieve this?
