sqlite queries return nothing! (select statement)

sqlite queries return nothing! (select statement)

I have a table in which there's a column of type BLOB. Another column is
of type 'text'. Something like:
CREATE TABLE Tbl(TXT text, BLB blob);
Now I've inserted a few records using:
INSERT INTO Tbl(TXT) VALUES("whatever");
As you can see nothing was defined for BLB. But each time that I issue a
query like:
SELECT * FROM 'Tbl' WHERE 'TXT'="whatever";
I get nothing at all without any error message or anything. My primary
guess was that the problem might have something to do with BLB being null
or undefined or something like that. Any ideas?
