Hi
I have these SQL in a cursor of a procedure, variables are declared in procedures,
These SQL are taking time when called in reports,
STATS are updated one,
Please suggest any modifications to these SQL code from performance point of view or better approach,
/* I tried to attach .txt but not attaching so i have pasted SQL and PLAN also.*/
// FIRST SQL **/

First thing that caught my eyes was this
| Quote: |
TABLE ACCESS FULL Object owner=SYS Object name=DUAL Cost=8 Cardinality=8168
|
A cardinality of 8168 on dual?
Sounds strange; can someone shed a light on that?
secondly: how many rows does table INT_INSTRUMENT_HIER_LVL contain?

First thoughts,
looking at the query, I bet we could factor out the
SELECT hier_lvl.instrument_hier_level_no
, hier_lvl.instrument_type_hier_scheme_id
, hier_lvl.instrument_hier_level1_id
, hier_lvl.instrument_hier_level2_id
, hier_lvl.instrument_hier_level3_id
, hier_lvl.instrument_hier_level4_id
, hier_lvl.instrument_hier_level5_id
, hier_lvl.instrument_hier_level6_id
FROM INT_INSTRUMENT_HIER_LVL hier_lvl
, INT_REP_TEMP_DIM_COL_DET dim_col
WHERE hier_lvl.instrument_hier_level_id =
dim_col.entity_id
AND hier_lvl.instrument_hier_level_no =
dim_col.level_no
AND dim_col.entity_ty = 'AC'
AND dim_col.template_id = temp_id
AND dim_col.current_rec_in = 'Y'
AND dim_col.status_in = 'A'
Which seems to be repeated quite a few times. The WITH clause allows us to do this once and reuse,
i.e.
WITH x AS ( SELECT hier_lvl.instrument_hier_level_no
, hier_lvl.instrument_type_hier_scheme_id
, hier_lvl.instrument_hier_level1_id
, hier_lvl.instrument_hier_level2_id
, hier_lvl.instrument_hier_level3_id
, hier_lvl.instrument_hier_level4_id
, hier_lvl.instrument_hier_level5_id
, hier_lvl.instrument_hier_level6_id
FROM INT_INSTRUMENT_HIER_LVL hier_lvl
, INT_REP_TEMP_DIM_COL_DET dim_col
WHERE hier_lvl.instrument_hier_level_id =
dim_col.entity_id
AND hier_lvl.instrument_hier_level_no =
dim_col.level_no
AND dim_col.entity_ty = 'AC'
AND dim_col.template_id = temp_id
AND dim_col.current_rec_in = 'Y'
AND dim_col.status_in = 'A' )
SELECT ...
..
WHERE
(
... inmt.inmt_type_hierarchy_level_no
, inmt.inmt_type_hierarchy_scheme_id
, inmt.inmt_type_hierarchy_level1_id
, inmt.inmt_type_hierarchy_level2_id
, inmt.inmt_type_hierarchy_level3_id
, inmt.inmt_type_hierarchy_level4_id
, inmt.inmt_type_hierarchy_level5_id
, inmt.inmt_type_hierarchy_level6_id
) IN (
SELECT * FROM x )
....
Although, I can't see where "temp_id" comes from, is this a column or a bound variable?

Thanks Mchadder
Thanks for responding,
Yes I learned a new WITH clause today,
I will try with it, but i think some difference is there in the where clause of the repeated inner query will look again into it ,
If you find any other flaw or any suggestion please come up.
Thanks

1st SQL
It's a big SQL, so I can't say that I've studied it closely, but...
I have two concerns with this plan:
1. The lines containing INDEX RANGE SCAN: An index range scan means that Oracle is reading some but not necessarily all of the index. eg. If the table (and index) has 100 million rows, then that step of the plan may be reading anywhere from 1 to 100 million rows. It's a bit iffy.
If EACH range scan is reading 1-10 rows, I wouldn't be concerned, but it's very hard to tell without tracing the SQL.
2. The plan uses all Nested Loops joins, indicating that Oracle thinks it is a low-volume SQL. But with those RANGE SCANs, I'm not so sure. Look at the join order: single row of BUSINESS_UNIT, then range scan of INT_REPORT_TEMPLATE_DET, then range scan of ACCOUNT, then range scan of DAILY_ACCOUNT_RETURNS.
Say (for instance) that one Business Unit had 10 INT_REPORT_TEMPLATE_DET, each of which had 10 accounts, each of which had 365 DAILY_ACCOUNT_RETURNS. That means 10x10x365 = 36500 rows. That's not such a huge number, but then you have to lookup another 8 tables 36500 times; it starts to add up.
The question is: are there any predicates in the SQL that are MORE constraining that the one on BUSINESS_UNIT? If so, the the SQL should be driving off a different table.
To get further information on both of these points, you need to trace the SQL and run it through TK*Prof. Lookup TKPROF in the Oracle Utilities manual.
Feel free to post the TKPROF results here if you want further advice.
