Hi, I have been debugging why the ADO CommandTimeout property has no effect on Postgres Queries and I believe that it is being ignored. Is this something that could be modified in a future ODBC Driver release. What I would like to see is an auto prepending of this value to a SQL Query being passed in if set.
I understand that the statement_timeout config parameter in postgres can be configured at the server level, user level and query level. I have tested each and they work as expected. What I wasn't expecting was for my CommandTimeout to be ignored / not passed through.
e.g.
Set p_objConn = Server.CreateObject("ADODB.Connection")
p_objConn.ConnectionString = "SOME DSN or DSNLess Connection String"
' e.g. DB.ConnectionString = "Driver={PostgreSQL UNICODE};Server=localhost;Port=5432;UID=someuser;PWD=somepassword;Database=somedatabase;"
p_objConn.ConnectionTimeout = 10
p_objConn.Open
p_objConn.CommandTimeout = 30 ' This has no effect on queries run against Postgres !!
If The ADO CommandTimeout value is set, could this be detected, check that the SQL Query hasn't already got a statement_timeout value and if not prepend the SQL Query as follows:
SET statement_timeout = 30000;
SELECT somedata FROM
somedatabasetable WHERE somevalue=anothervalue,
Many thanks in advance.
Feel free to contact me if you need any further information.
