Errors sending Blob to DB

От
"Derrick Betts"
Дата:
I am using Delphi7 and PostgeSQL 7.3.2
 
My DB table is as such
    Create Table files (
emalid varchar(80),
memocolumn text,
savedfile oid );
 
I cannot post Blobs to the DB that are larger than a typical icon. If the Blob is small, it goes through just fine. When I try to send a larger object to the DB, I get a Postgres error:

SQL Error: pqReadData() - read() failed: errno=0

What am I doing wrong with this and what can I change to eliminate the error and get larger files into the database?

Thank you,
Derrick

It would be helpful to see the code that you actually wrote. Just the part that initiates the transfer of the blob though.
