Обсуждение: SQLExecute get result to client?

Hello,

  I have one question. It's not fatal error but very annoying thing.

My configuration:
-----------------
 server - Linux RH 7.2 + postgresql 7.1.3
 client - WinNT 4.0 Workstation + postgresql ODBC 7.01.00009

Problem description:
--------------------
I have application (without source) that test table with:

SQLPrepare "select * from table" with return code 0
SQLNumResultCols  with return code 0
SQLDescribeCol  with return code 0    (for each column)
SQLExecute  with return code 0
SQLFreeStmt  with return code 0

There is difference between Postgres and MSSQL ODBC. Postgres load whole
result to client in SQLExecute but MSSQL not. Table have +-500000 rows and
transfer through net takes very long time.

So my question is: Exists some patch to fix this? Or could you help me
with basic information what I have to change?

Thanks

Luf

Turn on the Use Declare/Fetch option.
It would work well with read-only applications.

I tried this. But it has no effect. I'll try it once more.
