ODBC

PostgreSQL
I am using Microsoft Visual FoxPro to connect VIA ODBC using both
a DSN connection and a DSNLess Connection. The DSNLess connection is
Waaaayyyyy... slower than the DSN connection and I am having a problem
trying to figure out what ODBC settings affect performance this much.

using DSN i can pull 4 fields x 953 rows in .266 seconds :)
however using a DSNLess connection the same query takes >179 seconds
(ouch =-O)

the DSN connection settings are all the default expet for
Database = systemdata
Server = 192.168.10.94
Username = postgres
I have been messing around with the DSNLess connection and have tried
changing quite a few of the setting but can't get the speed up, here are
some of the settings. As you can see they are pretty much the same.

lcSqlDriverName = "PostgreSQL "
lcSqlServerName ="192.168.10.94 "
lcSqlDatabase=" systemdata""
lcSqlUserName=" postgres"
lcSqlPassword=" "
lcSqlPort="5432 "
lcSqFetch="100"

lcSqOptimizer=" 1"
lcSqKsqo="1"
lcSqSqUniqueInd ex = "1"
lcSqBoolsAsChar = "1"
lcSqMaxVarcharS ize = "254"
lcSqMaxLongVarc harSize = "8190"
lcSqExtraSysTab lePrefixes = "dd_;"
lcSqProtocol = "6.4"
lcSqUpdatableCu rsors = "1"
lcSqLFConversio n = "1"
thanks......... .....

Ouch indeed. Are you sure all other details are the same? That's almost too
slow.

I think if you turn the logging options on in the driver settings for your DSN
connection you can get a trace that shows you your settings.

There's also an ODBC list that might give you more help.

Maybe a dumb question - I'm new to ODBC. How do I install an Access ..mde file on a user's workstation and create the ODBC connection to the backend SQL Server database without having to go through the Administrative Tools>Data SOurces (ODBC) menu? IS there a way to do this with VBA code from my installer disk, or by simply copying a file onto the user's PC? Any help is appreciated. LQ

Hi All, I am currently trying to link in Access 97 to a table in a MSSQL 7 server. Initially the link is fine, however, when I close the access database and re-open it from the same network lacation on a different machine, it tells me that the ODBC connection to 'SQL Server Name' failed. How can I create the linked table permenant no matter what machine the networked database is opened on?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
