I have written a stored procedure in C that opens a file and returns it as a
varchar.  The file is 1.5M in size.  I then execute the stored procedure with
the following SQL.


SELECT name, GetFile() AS Test FROM dummy WHERE name = 'One';


When I do this on my Unix system via the Perl DBI it works perfectly.

When I do the same on my Windows machines via Borland C++ Builder and
the ODBC driver, two things go wrong.

1) The Query object used to invoke the SQL indicates that no records were
returned.

This seems to be a problem when any stored procedure is trigger by a SELECT
statement
regardless of the data returned.  I have another stored procedure that returns
a single BYTE and it fails in the same manner.  However, querries that do not
invoke
stored procedures set the RecordCount property of the C++ Builder TQuery object
correctly.


2) The data returned is truncated to 32769 BYTES when it should be 1.5M.

I have tried modifying various settings in the driver, but nothing I have
changed seems to
have any effect.

Thanks in advance for the help.

I am running version 7.2 of PostgreSQL on Solaris 5.8.
I have the most recent version of the ODBC driver.
I am running version 5.0 of C++ Builder Professional on a Windows 2000 box.


Jim
