Hi

Please can any body analyse this query and give recommendations

Select distinct inv_investments.id
FROM ((SELECT invest_id ID
FROM sortfolio_contents
WHERE sortfolio_id = 5115003
AND invest_type IN ('project')
AND is_Added_By_Expression = 1)) sortfolio_investments,
(SELECT c.currency_code code
FROM cmn_currencies c
WHERE c.is_active = 1) obj_currency,
inv_investments
WHERE inv_investments.is_active = 1
AND (inv_investments.purge_flag = 0 or
inv_investments.purge_flag is null)
AND obj_currency.code = inv_investments.currency_code
AND 0 =
(CASE WHEN inv_investments.odf_object_code = 'project' THEN
(SELECT is_template FROM inv_projects WHERE prid = inv_investments.ID) ELSE 0 END)
AND inv_investments.ID = sortfolio_investments.ID
AND inv_investments.status IN (1, 5, Cool

AND inv_investments.id IN
(SELECT ID
FROM ODF_CA_INV
WHERE ODF_OBJECT_CODE IN
(SELECT OE.OBJECT_CODE
FROM ODF_OBJECT_EXTENSIONS OE,
ODF_OBJECTS O,
CMN_SEC_CHK_USER_R_V S
WHERE S.USER_ID = 5545073
AND O.CODE = OE.OBJECT_CODE
AND OE.EXTENSION_CODE = 'inv'
AND S.OBJECT_TYPE = 'RECORD'
AND S.PERMISSION_CODE = 'READ'
AND S.OBJECT_CODE = O.RIGHT_CODE
UNION
SELECT 'project'
FROM CMN_SEC_CHK_USER_R_V0
WHERE USER_ID = 5545073
AND PERMISSION_CODE = 'prProjectViewer'
AND OBJECT_ID = 663)
UNION (SELECT OBJECT_INSTANCE_ID
FROM CMN_SEC_CHK_USER_V0
WHERE USER_ID = 5545073
AND PERMISSION_CODE = 'prProjectViewer'
AND OBJECT_ID = 663
UNION
SELECT OBJECT_INSTANCE_ID
FROM CMN_SEC_CHK_USER_V0
WHERE USER_ID = 5545073
AND PERMISSION_CODE = 'READ'
AND OBJECT_ID IN
(SELECT S.ID
FROM ODF_OBJECT_EXTENSIONS OE,
ODF_OBJECTS O,
CMN_SEC_OBJECTS S
WHERE O.CODE = OE.OBJECT_CODE
AND OE.EXTENSION_CODE = 'inv'
AND S.OBJECT_TYPE_CODE = 'RECORD'
AND S.OBJECT_CODE = O.RIGHT_CODE)))

I put this in oracle sql tuning advisor and does not get much recommendations.can any body tell some recommendations

Thanks
Ganga

Nobody can tune a SQL by just looking at it.

Information that is required to tune SQLs,

Ganga, your code is unreadable. I'll put it through a code formatter for you:

       inv_investments
WHERE  inv_investments.is_active = 1
       AND ( inv_investments.purge_flag = 0
              OR inv_investments.purge_flag IS NULL )
       AND obj_currency.code = inv_investments.currency_code

Looks like the formatter struggled with that. I can't tell what's supposed to go with what at the end there.
I suspect those unions can all be made union alls, which might help.

Hi

Thanks for all your suggestions.Will provide you now with original plan(having high costs) and the oracle recommended plan (with low costs).So can any body check this and give some recommendations

First of all you could format your orginal query so that's actually readable, since John's attempt didn't really suceed, and repost it here.
Secondly you could tell us what you did to get the second plan.
Thirdly you could format the second plan so that looks like the first plan where columns are actually lined up.

Worry less about cost and more about real world timings would be my advice. I've seen altered queries with costs 5 times higher than 'base', run 150+ times faster than 'base'.

2)By applying sql tunining advisor ,it recommends this plan with alternate plan finding.

3)please find the formatted plan(which was recommended by oracle)

Without more detail what I can suggest/ask so far is:

How many rows are returned?
How long is the execution time currently?
What is the target execution time?
Have you tried breaking it apart to see if one part of it is the obvious performance hole?

Hello again. Ganga, I don't understand the problem. If I understand you correctly, the SQL Tuning Advisor
has come up with some advice. What is the issue? Does it actually run more slowly when you accept it?
Of course, you must not be put off by the values in the "cost" column of the plans: they have no absolute meaning at all,
they are only the relative cost of each step.
