I need the following output

  • Queue Name: Name of the queue
  • State: 0 Ready,1 Waiting, 2 Processed, 3 Expired - of the queue table
  • Count: count the number of records in the queue table of that state.

Example

Queue Name         State         Count
---------------------------------------
Email_Q            Processed      5939
Email_response_Q   Waiting         133

I constructed the following SQL

SELECT 'select ''' || owner || '.' || name || ''' queue_name, 
        decode(state,0,''Ready'',1,''Waiting'',2,''Processed'',3,''Expired'',''?'') state, 
        count(*) count 
        from ' || owner || '.' || queue_table || 
        ' where q_name = ''' || name || ''' group by state' cmd
  FROM all_queues
 WHERE owner IN ('AMADEUS')
 ORDER BY owner, name;

I am able to construct all the selects for the Queue tables. But I would like to get the output using a select statement.

I was thinking of pipeline functions or use of a global temporary tables. Any help will be much appreciated.
