Postgresql and VBA - Connection Timeout

second timeout limit.

Has anyone found a way to make this work?� Thanks.

I found that the default of 0 meaning no timeout doesn't seem to work.

What happens if you set cnnCmd.CommandTimeout = 60 for the sleep test of 50?

Set cnnCmd = cnn.Execute("select pg_sleep(50);")

Realized you are setting CommandTimeout = 0.

Maybe this thread will help?:
/messages/by-id/1516895461336-0.post@n3.nabble.com

Otherwise I would see if someone over on the -odbc list:

https://www.postgresql.org/list/pgsql-odbc/

could help.

Thank you Adrian,

The link you sent had an answer that worked.

I had to edit the psqlodbc35w.dll file and change SET statement_timeout = %d to SET statement_timeout = 0 .

Somewhere in the thread, Hiroshi Inoue mentioned that a SQL_QUERY_TIMEOUT statement was built into the driver starting with version 9.5 of the driver, but all of my attempts to find documentation on how to use this feature in VBA have failed.

It certainly would be a better way to handle this. Can anyone point me at some documentation? I've copied this to the ODBC list as well.

Thanks everyone who replied.

Wayne

Hello Hiroshi,

Thank you for your reply.

Your suggestion to try setting cnn.CommandTimeout = 0 before calling cnn.Execute() worked perfectly and was exactly the solution I needed. Since the cnn connection was what owned the Execute, it was the object that needed the Command Timeout. That is a much nicer solution than editing the DLL.

I am very grateful for your help.

Thank you,

Wayne
