Accessing PGSQL

Hi!

Is there a way to execute a SQL query directly from a Win NT machine, on a
pgSQL database that is remotely installed?

I tried using CRecordset Object to connect to this remote pgSQL database.
But if I have a very large database (say 10,000 records), then searching for
a particular record takes lot of time as we need to traverse through all the
records in CRecordset.

I can use m_strFilter property of CRecordset, but then I have to open the
database again and this is also very time consuming process.

So I am looking for a quick way to locate a particular record in a
collection of say 10,000 records.

Is there a work-around for this?


Regards,
Vikram

I'm not sure you need a work around and 10,000 records is not very large. I
have a few databases with well over 10 million records, and I would consider
these moderately sized.

First of all, you seem to be confusing ODBC with a database class library. They
are not the same.

From an ODBC perspective, one could execute SQLExecDirect(...) to execute a SQL
query.

There could also be an issue with your query needing an index, but that may be
a different matter.
