Determine the Process ID of a Running Query

In the previous example you learned how to obtain the query ID and process ID (PID) for a completed query from the SVL_QLOG view.

You might need to find the PID for a query that is still running. For example, you will need the PID if you need to cancel a query that is taking too long to run. You can query the STV_RECENTS system table to obtain a list of process IDs for running queries, along with the corresponding query string. If your query returns multiple PIDs, you can look at the query text to determine which PID you need.

To determine the PID of a running query, issue the following SELECT statement:

Copy
select pid, user_name, starttime, query from stv_recents where status='Running';
