This is completely off topic, it is a simple programming error, I am sure.
Your lengthBLOB outside of the function is fishy, you didn't show even
how and where you have declared it. Your example proofs that not the call to
blobGet.getBinaryLength() is the problem, but the assignment to
lengthBLOB, and lengthBLOB is a reference, to what?
