Re: question about timeout attributes

Hi Joy,

The SQL_ATTR_CONNECTION_TIMEOUT only applies to calling SQLConnect. If the remote server does not accept the connection, this is the maximum amount of time it will take for the function to return.

The SQL_ATTR_QUERY_TIMEOUT is not supported by the psqlodbc driver.

Subject: [ODBC] question about timeout attributes

Hi there,

I am playing out these timeout attributes:
SQL_ATTR_CONNECTION_TIMEOUT and
SQL_ATTR_QUERY_TIMEOUT. Basically I set the connection
timeout to 1 sec after a connection is made and query
timeout to 1 sec after a statement handle is
allocated. And then I did the following:

1. lock a table (say dummy) manually in exclusive
mode.

2. run my program which try to query this dummy table
using the odbc interface with the same statement
handle above.

To my understanding, if these timeout features are
supported correctly. My query should timeout after 1
sec. But in my test, the query just waits there
forever.

My question is therefore whether these timeout
attributes are supported by the postgresql odbc driver
at all or there is a problem in my test.

Any suggestions or recommendations are highly
appreciated.

Thank you
Joy
