Hello Experts,

I am trying to tune this query which is taking 10 mins. to execute. I need your suggestions on this that how i can improve the response time of this query. Can anybody provide me with some suggestions regarding some changes in where clause or anything else which will improve the response time of this query. Pls. help me on this as this is urgent and a matter of high priority.Version is 9.2.0.5 and O.S. win-2003

I see from your explain plan that you have indexes. Have your tables, indexes, and indexed columns been recently analyzed? I do not think that you need all of those first_rows hints, but I do not know that it causes any harm to have them either. I would be inclined to remove all but the first first_rows hint. Have you tried running each subquery separately to see which part is taking the longest? One thing that I would do is eliminate some of the unnecessary levels of subqueries and extra calls to the dual table. For example, the following subquery:

(SELECT NVL ((SELECT /*+FIRST_ROWS*/ 
                     RI.RECIPIENT_NAME 
              FROM   ARV_SOP_ACTION_ITEM AI, ARV_SOP_RECIPIENT_INFO RI 
              WHERE  AI.WORKSHEET_ID = W.WORKSHEET_ID 
              AND    AI.RECIPIENT_INFO_ID = RI.RECIPIENT_INFO_ID 
              AND    AI.DELIVERABLE_CD = 12007 
              AND    AI.DELIVERY_METHOD_CD != 13014 
              AND    AI.ACTION_ITEM_STATUS_CD in (38002, 38003)), ' -- ') 
 FROM   DUAL)


can be replaced with:

(SELECT NVL (RI.RECIPIENT_NAME, '--') 
 FROM   ARV_SOP_ACTION_ITEM AI, ARV_SOP_RECIPIENT_INFO RI 
 WHERE  AI.WORKSHEET_ID = W.WORKSHEET_ID 
 AND    AI.RECIPIENT_INFO_ID = RI.RECIPIENT_INFO_ID 
 AND    AI.DELIVERABLE_CD = 12007 
 AND    AI.DELIVERY_METHOD_CD != 13014 
 AND    AI.ACTION_ITEM_STATUS_CD in (38002, 38003))


I would make replacements like that in each possible such place. It may allow the optimizer to select a better execution plan that can join tables more directly, without the dual table in the middle.

On second thought, I think I see why you have the extra calls to the dual table. If you just want to replace a value when it is null, then you do not need the outer query. However, if you want to supply a value when the inner query does not return a row at all, then you will need the outer query. So, I guess, I would try executing each subquery separately and finding which is taking the longest, then examine that subquery in more detail to see what can be done. I noticed that your last where clause relies on an implicit date conversion, which is generally a bad idea, because it will cause the query to fail if the nls_date_format does not match.

Another thing that you might try is moving the inline views in the select clause to the from clause without the calls to dual and nvl, then outer joining them and putting the nvl functions in the outer select, so instead of:

That would allow the tables to join directly and eliminate the calls to the dual table, but still allow for a value substitution when the subquery does not produce a row.

I also noticed that you have a number of subqueries that select from the same tables, with different filtering conditions. You could eliminate some duplication by using the with clause or subquery factoring clause. So, instead of:

SELECT (SELECT some_column
        FROM   ARV_SOP_ACTION_ITEM AI, ARV_SOP_RECIPIENT_INFO RI 
        WHERE  AI.RECIPIENT_INFO_ID = RI.RECIPIENT_INFO_ID
        AND    some_filter_conditions),
       (SELECT some_other_column
        FROM   ARV_SOP_ACTION_ITEM AI, ARV_SOP_RECIPIENT_INFO RI 
        WHERE  AI.RECIPIENT_INFO_ID = RI.RECIPIENT_INFO_ID
        AND    some_other_filter_conditions)


you could have:

WITH repeating_query AS
  (SELECT *
   FROM   ARV_SOP_ACTION_ITEM AI, ARV_SOP_RECIPIENT_INFO RI 
   WHERE  AI.RECIPIENT_INFO_ID = RI.RECIPIENT_INFO_ID)
SELECT (SELECT some_column
        FROM   repeating_query 
        WHERE  some_other_filter_conditions),
       (SELECT some_other_column
        FROM   repeating_query
        WHERE  some_filter_conditions)
