Large BLOB object in CPP Builder

In C++ Builder 4....
I get an error msg when writing a large (761,000+ bytes) TBlobField
object to MSSQLServer database.
The error msg reads:

"Multiple records found, but only one was expected"

This does NOT occur on smaller files (26K). I did not check the
"threshold" of where it broke. There is one and only one record being
written, so I suspect the message
is bogus.

I am using BDE and have changed the BLOB size to 800K.

Solved by installing updated version of ODBC - older version had this
problem.
