Optimizing an sql query

Hi all,
I guess the issue with huge tables won't end :(, I have a table with 100 millions rows (1 unique index, 2 timestamps column and 15 numbers),
I have to backuo this table, is it faster to just copy it into another table or export it into a dump file.
Either way i need in my processing to copy this table into another one and i have some question concerning how to make this work a little faster:
since i am coying the hole table (i guess it would be a full scan), verifying the well state of my index (doing a coalesce for example) would fasten the processus ?
the problem is that i don't know when doing the insert into the target table, how oracle will process, i ll explain myself, would it put the whole data in the memoy then copy it or will it proceed sequentially, coping an amout of rows commit it then coping another amount ... because i may think that creating a script that copy for example 200000 each time then commit it would be faster but may be i am wrong (correct me).
Well this is to say if you have a book that treats this issue (well optimization anyway) that would be a great help

The fastest way to copy a table is CTAS - create table as select statement with nologging option.
In this way oracle creates a temporary table and then renames it.
During table creation there is no redo generation because you specified NOLOGGING option, and no UNDO generation because temporary tables doesnt generate undo.
You can encreease the speed even more if you parallelize this statement using PARAllel option of creating table.

Optimizing an SQL Query using Oracle SQL Developer

Hi ,
Currently i am using Oracle SQL Developer as my Database IDE .
Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
For example assume i am having a query as :
Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
Please share your ideas , thanks in advance .

1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.

Need optimized T-SQL query

Hello,
I have a requirement where a table has ItemId & AuthenticationString (default to replicate('0',8000)) and other table has ItemId & CodeNumber. If in second table there exists a CodeNumber for a ItemId then AuthenticationString should have it as 1
for that position of CodeNumber.
CREATE TABLE ItemId
(ItemId INT,AuthenticationString VARCHAR(8000))
CREATE TABLE CodeNumber
(ItemId INT,CodeNumber SMALLINT)
INSERT INTO ItemId
SELECT 1,REPLICATE('0',8000)
INSERT INTO CodeNumber
VALUES (1,1)
INSERT INTO CodeNumber
VALUES (1,3)
INSERT INTO CodeNumber
VALUES (1,7)
INSERT INTO CodeNumber
VALUES (1,8)
output for this example should be '10100011000000000............' in AuthenticationString field. I am doing now by while loop & STUFF function. I am using SQL Server 2005.
Thanks in Advance.

CREATE TABLE ItemId

URGENT HELP Required: Solution to avoid Full table scan for a PL/SQL query

Hi Everyone,
When I checked the EXPLAIN PLAN for the below SQL query, I saw that Full table scans is going on both the tables TABLE_A and TABLE_B
UPDATE TABLE_A a
SET a.current_commit_date =
(SELECT MAX (b.loading_date)
FROM TABLE_B b
WHERE a.sales_order_id = b.sales_order_id
AND a.sales_order_line_id = b.sales_order_line_id
AND b.confirmed_qty > 0
AND b.data_flag IS NULL
OR b.schedule_line_delivery_date >= '23 NOV 2008')
Though the TABLE_A is a small table having nearly 1 lakh records, the TABLE_B is a huge table, having nearly 2 and a half crore records.
I created an Index on the TABLE_B having all its fields used in the WHERE clause. But, still the explain plan is showing FULL TABLE SCAN only.
When I run the query, it is taking long long time to execute (more than 1 day) and each time I have to kill the session.
Please please help me in optimizing this.
Thanks,
Sudhindra

Check the instruction again, you're leaving out information we need in order to help you, like optimizer information.
- Post your exact database version, that is: the result of select * from v$version;
- Don't use TOAD's execution plan, but use
SQL> explain plan for <your_query>;
SQL> select * from table(dbms_xplan.display);(You can execute that in TOAD as well).
Don't forget you need to use the {noformat}{noformat} tag in order to post formatted code/output/execution plans etc.
It's also explained in the instruction.
When was the last time statistics were gathered for table_a and table_b?
You can find out by issuing the following query:select table_name
, last_analyzed
, num_rows
from user_tables
where table_name in ('TABLE_A', 'TABLE_B');
Can you also post the results of these counts;select count(*)
from table_b
where confirmed_qty > 0;
select count(*)
from table_b
where data_flag is null;
select count(*)
from table_b
where schedule_line_delivery_date >= /* assuming you're using a date, and not a string*/ to_date('23 NOV 2008', 'dd mon yyyy');

How to measure the performance of sql query?

Hi Experts,
How to measure the performance, efficiency and cpu cost of a sql query?
What are all the measures available for an sql query?
How to identify i am writing optimal query?
I am using Oracle 9i...
It ll be useful for me to write efficient query....
Thanks & Regards

I am using Oracle 9i... You might want to start with a feature of SQL*Plus: The AUTOTRACE (TRACEONLY) option which executes your statement, fetches all records (if there is something to fetch) and shows you some basic statistics information, which include the number of logical I/Os performed, number of sorts etc.
This gives you an indication of the effectiveness of your statement, so that can check how many logical I/Os (and physical reads) had to be performed.
Note however that there are more things to consider, as you've already mentioned: The CPU bit is not included in these statistics, and the work performed by SQL workareas (e.g. by hash joins) is also credited only very limited (number of sorts), but e.g. it doesn't cover any writes to temporary segments due to sort or hash operations spilling to disk etc.
You can use the following approach to get a deeper understanding of the operations performed by each row source:
alter session set statistics_level=all;
alter session set timed_statistics = true;
select /* findme */ ... <your query here>
SELECT
         SUBSTR(LPAD(' ',DEPTH - 1)||OPERATION||' '||OBJECT_NAME,1,40) OPERATION,
         OBJECT_NAME,
         CARDINALITY,
         LAST_OUTPUT_ROWS,
         LAST_CR_BUFFER_GETS,
         LAST_DISK_READS,
         LAST_DISK_WRITES,
FROM     V$SQL_PLAN_STATISTICS_ALL P,
         (SELECT *
          FROM   (SELECT   *
                  FROM     V$SQL
                  WHERE    SQL_TEXT LIKE '%findme%'
                           AND SQL_TEXT NOT LIKE '%V$SQL%'
                           AND PARSING_USER_ID = SYS_CONTEXT('USERENV','CURRENT_USERID')
                  ORDER BY LAST_LOAD_TIME DESC)
          WHERE ROWNUM < 2) S
WHERE    S.HASH_VALUE = P.HASH_VALUE
         AND S.CHILD_NUMBER = P.CHILD_NUMBER
ORDER BY ID
/Check the V$SQL_PLAN_STATISTICS_ALL view for more statistics available. In 10g there is a convenient function DBMS_XPLAN.DISPLAY_CURSOR which can show this information with a single call, but in 9i you need to do it yourself.
Note that "statistics_level=all" adds a significant overhead to the processing, so use with care and only when required:

How to get cm:search to use the max attribute when creating the SQL query?

When we use the max attribute in the cm:search tag, it does not seem to honor the max attribute when creating the SQL query. However, the result returned from the tag is limited to the number specified by the max attribute. Then the tag seems to work as intended, but the performance will be sub optimal when the SQL query returns unnecessary rows to the application.
We use the cm:search tag to list the latest news (ordered by date), and with the current implementation we have to expect a decrease in performance over time as more news is published. But we can’t live with that. We need to do the constraint in the SQL query, not in the application.
The sortBy attribute of cm:search is translated to “order by” in the SQL query, as expected.
Is it possible to get cm:search to generate the SQL query with an addition of “where rownum <= maxRows”?

Hi Erik,
The behavior of a repository in regards to the search tag's max results parameter is dependent on the underlying repository's implementation. That said, the OOTB repository in WLP does augment the generated SQL to limit the number of rows returned from the database. This is done in the parsing logic. This behavior may differ with other repository implementations.

SQL query to fetch approximately 9000 rows

Hi,
I am using the following SQL query in a java class. Using JDBC to connect to an Oracle database using JRUN app server connection pooling.
SELECT PT.ACCOUNT_NUMBER,PAYMENT_REF_ID, TO_CHAR (PT.DATE_CREATED, 'MM/DD/YYYY'),
PT.AMOUNT_PAID, DECODE(STATUS_VALUE,'Cancelled','Canceled',STATUS_VALUE)
FROM EPAY_PAYMENT_TRANSACTIONS PT, EPAY_STATUS_LOOKUP SL
WHERE
PT.CLIENT_NAME = 'someclientname'
AND TO_CHAR(DATE_PAYMENT_SCHEDULED,'MM/DD/YYYY') = '08/28/2006'
AND PT.PAYMENT_STATUS = SL.STATUS_CODE
ORDER BY PT.DATE_CREATED DESC
EPAY_PAYMENT_TRANSACTIONS is a huge table consisting of thousands of rows. There are 4 indexes defined on this table but not on the columns used in the join condition of the query.
EPAY_STATUS_LOOKUP is a much smaller table mainly used for lookup consisting of some 100 rows.
The above query fetches approx 9000 records and takes a very long time to execute. Is there any way it can be optimized or we can change some attributes on the tables involved for speeding up the query?
Thanks in advance,
Nisha.

So the task is to avoid FTS on EPAY_PAYMENT_TRANSACTIONSWell, maybe...
But I believe that we have yet to hear more details about data distribution, execution plans and so on.
Because it all depends...

Full table scan is not something to be avoided at all cost.
Indexing - sometimes it is good,
sometimes it's just useless,
sometimes it only makes things worse...
It all depends on underlying data distribution. That's why I asked user527580 to tell us more.

How to modify a SQL query?

Hi all,
I am using Crystal Reports version 10. I have a number of reports that have been written by a software vendor wherby the name of the database they were connected to when the report was written is coded into the FROM command of the reports SQL query, eg "GCUK_2" in the of the SQL snippet below.
SELECT "Clients"."NAME", "Quotes"."QUOTE_ID", "Quote_Items"."UPRICE", "Quote_Items"."QTY", "Quote_Items"."UOM", "Quote_Items"."QUSAGE_ID", "Report_Control"."QUSAGEID", "Quote_Items"."STANDARD", "Quote_Items"."SECT_FLAG", "Quote_Items"."DISPORDER", "Quotes"."DESCRIPT", "Report_Control"."SECT_NAME", "Quote_Items"."CNT", "Category_and_Type"."TYPEDESC", "Quote_Items"."DESCRIPT", "Report_Control"."DISP_SORT"
FROM ((("GCUK_2"."schedwin"."QTE_CTRL" "Report_Control" INNER JOIN "GCUK_2"."schedwin"."QUSAGE" "Quote_Items" ON "Report_Control"."QUSAGEID"="Quote_Items"."QUSAGE_ID") LEFT OUTER JOIN "GCUK_2"."schedwin"."QUOTES" "Quotes" ON
I have tried setting the Datasource Location, but it doesn't change the query at all. I have read on another forum that you can generate another SQL query using the Database Expert, Current Connections, then right click the Add Command for the database you want to create a SQL command. Is this the only way to update the database names in the query?
Thanks,
Scott.

Hi Sourashree,
Thanks for that. All the reports were created by the vendor using tables as opposed to the command object. I would have thought that changing the datasource would automatically cause Crystal to rewrite the SQL query syntax, but this doesn't appear to be the case.
Yes, I've noticed that modifying the record selection will change the sql query. The only way I can see to change the database name in the query is to change to the desired databsource and then remove and re-insert the tables, which will then update the query with the correct name. However, this seems to be a convoluted way of changing the db name in the query.

Discoverer Report showing Null VS Show SQL query showing results !!!

I created a simple Cross Tab Discoverer report from a custom SQL which has a calculation for balances. The output is giving all null values even though there are balances. The output doesn't seem right. So I copied the query from Tools-->Show SQL and ran the query in the TOAD where I'm showing balances for the report. I don't understand why it is not showing in the discoverer. Please help.
Thanks

Issue in creation of group in oim database through sql query.

hi guys,
i am trying to create a group in oim database through sql query:
insert into ugp(ugp_key,ugp_name,ugp_create,ugp_update,ugp_createby,ugp_updateby,)values(786,'dbrole','09-jul-12','09-jul-12',1,1);
it is inserting the group in ugp table but it is not showing in admin console.
After that i also tried with this query:
insert into gpp(ugp_key,gpp_ugp_key,gpp_write,gpp_delete,gpp_create,gpp_createby,gpp_update,gpp_updateby)values(786,1,1,1,'09-jul-12',1,'09-jul-12',1);
After that i tried with this query.but still no use.
and i also tried to assign a user to the group through query:
insert into usg(ugp_key,usr_key,usg_priority,usg_create,usg_update,usg_createby,usg_updateby)values(4,81,1,'09-jul-12','09-jul-12',1,1);
But still the same problem.it is inserting in db.but not listing in admin console.
thanks,
hanuman.

hi vladimir,
i didn't find this 'ugp_seq'.is this a table or column?where is it?
It is a sequence.
See here for details on oracle sequences:
http://www.techonthenet.com/oracle/sequences.php
Most of the OIM database schema is created with the following script, located in the RCU distribution:
$RCU_HOME/rcu/integration/oim/sql/xell.sql
there you'll find plenty of sequence creation directives like:
create sequence UGP_SEQ
increment by 1
start with 1
cache 20
to create a sequence, and
INSERT INTO UGP (UGP_KEY, UGP_NAME, UGP_UPDATEBY, UGP_UPDATE, UGP_CREATEBY, UGP_CREATE,UGP_ROWVER, UGP_DATA_LEVEL, UGP_ROLE_CATEGORY_KEY, UGP_ROLE_OWNER_KEY, UGP_DISPLAY_NAME, UGP_ROLENAME, UGP_DESCRIPTION, UGP_NAMESPACE)
VALUES (ugp_seq.nextval,'SYSTEM ADMINISTRATORS', sysadmUsrKey , SYSDATE,sysadmUsrKey , SYSDATE, hextoraw('0000000000000000'), 1, roleCategoryKey, sysadmUsrKey, 'SYSTEM ADMINISTRATORS', 'SYSTEM ADMINISTRATORS', 'System Administrator role for OIM', 'Default');
as a sequence usage example.

Using a SQL Query in an Alert and Matching a String

I've created an alert in 12.0.4 using a SQL Query and the field that I'm trying to match is a string. Originally the query returned multiple rows but when the alert still didn't fire, I modified the query WHERE clause to return only one row:
NAME RESPONSE
Are area lights working? No
My expression in the metric is RESPONSE. In the Monitor I'm matching a string equal to No. (Do I need double quotes around the matchvalue? Single quotes? No quotes?) The metric is in the 15min scan group, the role is xMII Developers and I'm in that role. The monitor alert string is ' = '. Both metric and monitor are active and I've subscribed to the monitor. Other alerts in the 15min scan group (all based on tag queries) are firing off properly.
Why is nothing showing up in the Alert Log?

David,
Did you figure out the answer? If not, I will try to find someone to address your question.

Use realational operators in an SQL query??????

does any one knows how to use realational operators in an SQL query??????
i wud like to do something like
select decode(2<3,sysdate,sydate +1) from dual
but i know decode does not supports relational operators......
thanx and Regards
amyt

You can use a CASE statement which does support relational operators, or if you must use DECODE, then you can use something like:
SELECT DECODE(SIGN(2 - 3),-1,sysdate,sysdate - 1)
FROM dual;The SIGN function returns -1 if the expression is < 0, 1 if the expression is > 0 and 0 if the expression is 0. This works for numeric comparisions. You can use the GREATEST or LEAST functions in a similar fashion for character comparisions.
