CreateBlobStream, Stream Size

Question

My Code:

 stream := qry.CreateBlobStream(qry.FieldByName('aaa'), bmRead); 

The record in aaa is actually bigger than the stream's size,which is always 32786.Why?

Answer 1

According to my web searches, you need to increase the BLOB SIZE parameter in the BDE administrator:

• http://www.delphigroups.info/2/63/235340.html

The first of these threads suggests an alternative approach of setting RequestLive of the TQuery to be True.

The second thread dates from 1902 which would appear to be a rare sighting in the wild of the Y2K bug!
