Hello,

This error originates in DB Tools Execute Query.vi because the timeout period by default for the VI is 30 seconds. This is not a LabVIEW error. It is an error generated by the ODBC driver being used. This is easily overcome by increasing the timeout for the command as some queries may take longer than the default timeout period.

There are two potential solutions that have been found.
  1. Within the DB Tools Execute Query.vi, a while loop can be placed around the Invoke node for the execute method. The error response from this then needs to be monitored and the while loop condition set appropriately.

  2. Increase the command timeout using the DB Tools Set Properties.vi. Set this property to a level in seconds that will not expire as a result of running the query.
Hope this helps!
