Help with performance SQL tuning - Rewriting the query
Hi
I have serious performance issues with some 8 update queries
These were earlier taking 5 mins . Now taking 2.5 hours
This is one of the culprit UPDATE statement (These are 7 such other update statements on different tables but same logic)
We have change the update to MERGE and used PARALLEL hints but have not got desired results
There are appropriate indexes on the tables
Is there a way to rewrite the UPDATE statement in a better way to improve the performance
update TABLE_dob
set key_act =
(select skey from table_subs
where sub_act = sub_num)
where exists
(select 1 from table_subs
where sub_act = sub_num);
Table_DOB has 37 million records
Table_subs has 20 million records

Need help with performance & memory tuning in a data warehousing environment
Dear All,
Good Day.
We had successfully migrated from a 4 node half-rack V2 Exadata to a 2 node quarter rack X4-2 Exadata. However, we are facing some issues with performance only for few loads while others have in fact shown good improvement.
1. The total memory on the OS is 250GB for each node (two compute nodes for a quarter rack).
2. Would be grateful if someone could help me with the best equation to calculate the SGA and PGA ( and also in allocation of shared_pool, large_pool etc) or whether Automatic Memory Management is advisable?
3. We had run exachk report which suggested us to configure huge pages.
4. When we tried to increase the SGA to more than 30GB the system doesn't allow us to do so. We had however set the PGA to 85GB.
5. Also, we had observed that some of the queries involving joins and indexes are taking longer time.
Any advise would be greatly appreciated.
Warm Regards,
Vikram.Hi Vikram,
There is no formula about SGA and PGA, but the best practices for OLTP environments is for a give ammount of memory (which cannot be up to 80% of total RAM from server) you should make 80% to SGA and 20% to PGA. For Data Warehouse envs, the values are like 60% SGA and 40% PGA or it can be up to 50%-50%. Also, some docs disencourage you to keep the database in Automatic Memory Management when you are using a big SGA (> 10G).
As you are using a RAC environment, you should configure Huge Pages. And if the systems are not allowing you to increase memory, just take a look at the semaphore parameters, probably they are set lower values. And for the poor performance queries, we need to see explain plans, table structure and you would also analyze if smart scan is playing the game.
Regards. -
Query is Very Slow but after using sql tuning advisor the Query is fine
Currently we have Query which takes ages to retrieve small data set of 30 seconds.So i used the sql advisor and applied the profile now the same query comes in msec.This was tested on Test enviorement.

Help with an SQL Query on the Logger
We are running UCCE 8.5(3) and need help with an SQL query. When I run the below I would also like to see skill group information(name preferably)? Any help would be greatly appreciated!
select * from dbo.t_Termination_Call_Detail where DateTime between '10-11-2012 00:00:00:00' and
'10-11-2012 23:59:59:59'David, thanks for replying. Unfortunitly I don't know enough about SQL to put that into a query and have it return data. Would you be able to give an example on what the query would look like?

Kind regards,
NikOk, so I am going to be a little bit kinder then your first reply, but not much.
From what can tell you are doing medical management and are trying to select by AGE/GENDER CELLS and this is common when trying to deal with RBRVS.
This is by far some of the worst sql I have ever seen, sorry but it just is.
So please report this either as a new post or as a reply and:
1. At least post the table definitions and if you can some sample data.
2. Get rid of almost all the case selectors.
3. Describe the output you need.
As it is this is unreadable.
After that we can talk more.

Rewrite the query with out joins and group by
Hi,
This was an interview question.
Table Names: bookshelf_checkout
bookshelf
And the join condition between these two tables is title
We need to rewrite below query without using join condition and group by clause ?
SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
FROM bookshelf_checkout bc,bookshelf b
WHERE bc.title(+)=b.title
GROUP BY b.title;When I was in college, I read that most of the SELECT statements can be replaced by basic SQL operations (SET OPERATORS). Now I am trying to rewrite the query with SET operators but not able to get the exact result.
Kindly help me on this.
Thanks,
SuriSomething like this?
1 WITH books AS (
2 SELECT 'title 1' title FROM dual UNION ALL
3 SELECT 'title 2' FROM dual UNION ALL
4 SELECT 'title 3' FROM dual ),

Need Help in tuning of the query
Hi all,
Can any body help me how we can rewrite this query in
optimized way.
SELECT A.C1 AS COLUMN_1, B.C2 AS COLUMN_2
FROM A,B
WHERE A.C1 IN (
SELECT COLUMN_1 FROM(
(SELECT A.C1 AS COLUMN_1,
COUNT(C1) AS COUNT,
RANK() OVER (ORDER BY COUNT(C1) DESC) AS RANK
FROM A, B, C
WHERE A.C1 = B.C3
AND B.C2 = C.C1
AND <other conditions>
GROUP BY A.C1)
WHERE RANK <= 10)
AND A.C1 = B.C3
AND <other conditions>
ORDER BY A.C1
I am using <other conditions> are same in outer query and inner query also.
Thanks in Advance,Hi,
Yes exactly I am looking TOP-10 results the query is like this
SELECT A.C1 AS COLUMN_1, B.C2 AS COLUMN_2
FROM A,B
WHERE B.C2 IN (
SELECT COLUMN_1 FROM(
(SELECT B.C2 AS COLUMN_1,
COUNT(A.C1) AS COUNT,
RANK() OVER (ORDER BY COUNT(C1) DESC) AS RANK
FROM A, B, C
WHERE A.C1 = B.C3
AND B.C2 = C.C1
AND <other conditions>
GROUP BY B.C2)
WHERE RANK <= 10)
AND A.C1 = B.C3
AND <other conditions>
ORDER BY B.C2

Can any one help me , how can i rewrite the above query using analytical functions .,
SekharNot sure of your requirements but this mayhelp reduce your code;
<untested>
SUM (
CASE
WHEN tt.transactiontypecode IN
('WITHDRAWAL_CHECK_FEE', 'REJECTED_ACH_LOAD_FEE', 'WITHDRAWAL_ACH_REV', 'WITHDRAWAL_CHECK_REV',
'WITHDRAWAL_CHECK_FEE_REV', 'REJECTED_ACH_LOAD_FEE_REV', 'OVERDRAFT_FEE_REV','STOP_CHECK_FEE_REV',
'LOAD_ACH_REV', 'OVERDRAFT_FEE', 'STOP_CHECK_FEE')
THEN th.transactionamount
ELSE 0) feeAlso, you might want to edit your post and use [pre] and [/pre] tags around your code for formatting. -
hi ,
Actual i write the query like this , and run this query in sql developer ,
it will take more than 15 mins
alloc_details table -- 2 lac records
doc_details -- 2 lac records
query :
SELECT
a.activity
, sum( a.lamt ) lamt
, sum( a.lamt ) camt
FROM
alloc_detail a
WHERE
a.alc_code <>'JOB'
And a.alc_value is not null
And EXISTS ( SELECT
distinct b.doc_no
FROM
doc_detail b
WHERE
a.org=b.org
And a.doc_no=b.doc_no
And a.doc_type=b.doc_type
And ( b.dr_act_code='11111' OR b.cr_act_code='111111')
And ( ( trunc( b.doc_date ) >='01-jan-08' ) )
And ( ( trunc( b.doc_date ) <= '31-jan-08' ) )
GROUP BY
a.alc_value
Anyother way to rewrite the query .Is this query working? a.activity seems to be a "not a group by expression"
select a.activity,sum(a.lamt) lamt,sum(a.lamt) camt /* 2 times same sum - a typo ? */
from alloc_detail a
where a.alc_code != 'JOB' /* not equal presumed */
and a.alc_value is not null
and exists(select distinct b.doc_no
from doc_detail b
where a.org = b.org
and a.doc_no = b.doc_no
and a.doc_type = b.doc_type
and (b.dr_act_code = '11111' or b.cr_act_code = '111111')
and trunc(b.doc_date) >= '01-jan-08'
and trunc(b.doc_date) <= '31-jan-08'
group by a.alc_valuehow about applying predicates first
select a.alc_value,sum(a.lamt) lamt,sum(a.camt) camt
from (select alc_value,lamt,camt,org,doc_no,doc_type
from alloc_detail
where alc_code != 'JOB'
and alc_value is not null
) a,
(select distinct org,doc_no,doc_type
from doc_detail
where doc_date >= to_date('01-jan-08','dd-mon-rr')
and doc_date <= to_date('31-jan-08','dd-mon-rr') + 1 - 1/24/60/60
and (dr_act_code = '11111' or cr_act_code = '111111')
) b
where a.org = b.org
and a.doc_no = b.doc_no
and a.doc_type = b.doc_type
group by a.alc_valueRegards

Need some help with downloading PDF's from the net.
need some help with downloading PDF's from the net. Each time I try to click on a link from a website, if it takes me to a new screen to view a pdf, it just comes up as a blank black screen? any suggestions?
Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again. -
one question I am looking for help with is, when you hit the history button I want my last fifty pages to show up instead of just fifteen. Is it possible to change that setting?
TYThe History menu can only show that fixed maximum of 15 as that is hard coded.
Maybe this extension helps:

Newbie - help with a SQL query for a bar chart - Originally posted in APEX
I originally posted this in the APEX forum but someone there suggested this is more of a SQL question. Anyone out there who can provide some assistance?
Hi,
I'm a new user on APEX with no real SQL knowledge and I'm trying to build a dashboard with charts into an existing APEX application. Based on another application, I have come up with the following SQL code:
select null link
, CATEGORY label
, count (decode(PROJECT_STATUS,'1',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'2',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'3',PROJECT_ID))"On Hold"
, count (decode(PROJECT_STATUS,'4',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'5',PROJECT_ID))"Pending Review"
from GRAPO_PROHEADTRK
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')
group by CATEGORY
Order by COUNT(PROJECT_ID) DESC
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"
, count (decode(PROJECT_STATUS,'Recurring',PROJECT_ID))"Recurring"
, count (decode(PROJECT_STATUS,'Pipeline',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'Not Approved',PROJECT_ID))"Not Approved"
from PM_V2
where LOB='S2S' and (FUNCTIONAL_AREA='Accounts Payable' or FUNCTIONAL_AREA='Expense' or FUNCTIONAL_AREA='Procurement' or FUNCTIONAL_AREA='Fixed Assets')
group by FUNCTIONAL_AREA
Order by COUNT(PROJECT_ID) DESC
I'm getting a "Failed to parse SQL query!" error when I try to run validation.
Is this enough info for some assistance? Any help would really be appreciated.
Thanks,

group by CATEGORY
Order by COUNT(PROJECT_ID) DESCIs there a problem with the code above?
It's curious that the WHERE clause includes "PROJECT_STATUS='6'", but there is no pivoted column for project_status='6', like there is for '1' through '5'. That's not necessarily a mistake, and it wouldn't raise an error in any case.
Instead of
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')you could say
where PROJECT_STATUS IN ('1', '2', '3', '4', '5', '6')but that probably has nothing to do with your current problem.
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"

I'm getting a "Failed to parse SQL query!" error when I try to run validation.Is that an Apex error message? Sorry, I don't know anything about Apex.
If you can't get a more specific error message from Apex, then try debugging this statement in SQL*Plus. When you get it fixed, then you can copy it back into Apex.
If this is a SQL problem, then you should be able to re-create the problem in pure SQL.
If you can't re-create the problem in pure SQL, then it's probably an Apex problem, and belongs in the Apex forum, not here.
I don't see anything obviously wrong with your code, but I can't tell if, for example, you spelled a column name wrong, or if something has the wrong data type
Is this enough info for some assistance? Any help would really be appreciated.It wiould be better if you posted a completE script that people could run to re-create the problem, and to test their ideas.
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle (and any other software, such as Apex) you're using.
