Tuning sql (where order clauses)
Hello
This request is really slow, because it calls the function f to each line (table1 and table2 may have more than 10000 lines)
SELECT * FROM table1 t1 inner join tabl2 t2.............. WHERE where_clause_1 AND where_clause_2 AND f(t1.a, t2.a) = 'Y'
Returns 20 lines
Howerver, this query is much faster
SELECT * FROM table1 t1 inner join tabl2 t2.............. WHERE where_clause_1 AND where_clause_2 -- AND f(t1.a, t2.a) = 'Y'
Returns 24 ranks
I try that, but it is too slow:
SELECT * FROM ( SELECT ... FROM table1 t1 inner join tabl2 t2.............. WHERE where_clause_1 AND where_clause_2 ) WHERE f(t1_a, t2_a) = 'Y'
I would like to SELECT by where_clause_1 filter then where_clause_2 and finally the function call.
How can I do?
Thank you!
- SELECT * FROM)
- SELECT / * + NO_MERGE * /... THE T1 from table1 inner join t2 tabl2...
- WHERE where_clause_1
- AND where_clause_2
- )
- WHERE f (t1_a, t2_a) = 'Y '.
Indicates tips NO_MERGE optimizer outer query not combine and query the view of inline in a unique.

need to sql where condition evaluates to null
Hello
I have a branch_master and I am from the following sql querry
Select * from branch_master where branch_code =: p3_branch_code
Here, if I give a null value for: p3_branch_code, querry must return all the branch_code and the details. Incase if I give a particular value as "acts".
It must then return only the rows where the branch_code has value "acts".
Otherwise, if the value of the condition is null then querry should ignore the condition itself. Any help is appreciated
your
Dr.s.RaghuThe easiest sollution is
select * from branch_master where branch_code = nvl(:p3_branch_code,branch_code)but based on your index, you may need to do a SQL function returning a query and dynamically add the where the clause.

Hello
The goal for the following statement is so that it can be created as a point of view, but it takes 45 minutes minimum to complete. He returned about 200 000 lines and will gradually increase approximately 1,000 lines a day. Please bear with me, I couldn't get the output autotrace and dbms_xplan.display_cursor, because it takes ages to run. I've included output from v$ sql sql instead, hope this helps.

You can do, for example, by launching:
alter session set events '10046 trace name context forever, level 8'I think for now, is that your PGA is undersized for this query, because the time is especially dedicated to step "BUFFER FATE." If the report of tkprof including wait, reveals a lot of 'direct path read temp' and 'direct path write temp', then we know for sure.

When installing UCCE I use the ICMDBA to create the base of data but get this error:
"The sorting order of SQL Server on this computer is not binary. You can't go any further.
Anyone know how you can change the SQL sort order?
Hello
To change the SQL Server "Binary order", you will need to reinstall SQL Server and select 'Custom' config Binary order (Latin1_General) for installation.
Follow the instructions in this link:
See Chapter 10. This installation of SQL procedure is valid for all IPCC Enterprise versions in SQL Server 2000.

Tuning sql of a product to the seller without changing the sql statement
Hello
We have a product of the provider that generates the SQL statement. For a query, we get the answer in 15 seconds. But users are asking if we can bring it back to 5 seconds. Limitation is the query can not be changed. He used about 10 to 12 tables and bit complex query.
What kind of options could be evaluated if we are to improve the performance of a query (not sure if she could never be reduced to 5 seconds)
without making any change to the query.

Does anyone know how or where to enter in the ORDER BY clause when you use a SQL data source in a load rule? I prefer to do the classification in the State of charge rather than create a view on the side of the DB for this if possible.
According to the documentation "box of the SQL statement in Open SQL Data Sources dialog box provides Select, From, and where areas of text that helps you write SQL queries." You can specify multiple data sources, filter the display of folders and specify how the records displayed in the data editor Prep are classified and grouped. "but I have not found anywhere where you can order or group data. I don't need to be able to group data I want to just be able to control my data to make the most effective possible charging process.
I sort the data by inserting into the table of load, but Oracle is not necessarily insert the records in the table according to their order when you go.
We're currently on 11.1.1.3 Essbase and Oracle 11 g.
Any help is greatly apprecied.Just nail it on your WHERE clause in the area WHERE the. I think that you can even stick the entire statement (under the keyword "SELECT") within the area of SELECTION.

Setting of outsourcing work is not for a SQL Where clause
Im trying to outsource the WHERE SQL clause of a snapshot data (connecting to Siebel DB) and specify where clause in the run profile that does not work.
Snapshot of research: Select the name of siebel.s_org_ext
Parameter of outsourcing: where_clause_sql
Run the content of the profile:
phase. Phase1.snapshot.clt.where_clause_sql = name = "ABC0009".
#phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.
The above parameter retrieves all the records in the table. Below the profile execution retrieves just this record that seems to work fine.
Run the content of the profile:
phase. Phase1.snapshot.clt.snapshot_sql = select name from siebel.s_org_ext where name = 'ABC0009 '.
I want to outsource only where clause as there are many SQL and they are huge to maintain in the run profile.
I have attached a doco with screenshots that will help to understand more.
Hello
You must BE
-Choose "Select table or view" in the table of the snapshot Wizard selection page
&
-Use outsourced where clause
OR
-Choose "SQL" in the snapshot table selection wizard page.
&
-Outsourced use SQL snapshot
You can't mix and match options.

Published by: Deepak_J on March 11, 2010 16:37where: P1_DEPT_LOC IS NULL or dept_loc =: P1_DEPT_LOC
If dept_loc is not null better would be
where dept_loc = coalesce(:P1_DEPT_LOC,dept_loc)

A basic concept that is important to understand - sliders aren't 'sets of results' (sets of data in memory). A cursor is a series of executable steps (see plans run to cursor). It's like a program. An extraction run the program and output data. In general, which is repeated until the cursor (aka program) is no longer found the corresponding lines.
A ref cursor is a pointer or a handle for a such slider, passed to a caller, allowing the appellant to interface directly with this slider/program.
The slider more effective to create a search would be one without superfluous code and predicates and filters. Consider the following approach - a beefier PL/SQL procedure, do not try and play little tricks with SQL predicates in an attempt to create one (and probably not optimal) SQL.
(not tested/compiled code)
create or replace procedure SearchAddress( town IN SEARCHADDRESS.TOWN%TYPE, street IN SEARCHADDRESS.STREET%TYPE, postcode IN SEARCHADDRESS.POSTCODE%TYPE, refCur out ref_cursor ) is curHandle integer; res integer; searchSQL varchar2(1000); begin -- create base query searchSQL := 'select searchaddress_pk from searchaddress where 1 = 1 '; -- add dynamic predicates as needed if town is not null then searchSQL := searchSQL || 'and town = :town'; end if; if street is not null then searchSQL := searchSQL || ' and street = :street'; end if; if postcode is not null then searchSQL := searchSQL || ' and postcode = :postcode'; end if; -- create a DBMS_SQL cursor curHandle := DBMS_SQL.open_cursor; DBMS_SQL.parse( curHandle, searchSQL, DBMS_SQL.NATIVE ); -- bind the dynamic bind variables added as predicate values if town is not null then DBMS_SQL.Bind_Variable( curHandle, 'town', town ); end if; if street is not null then DBMS_SQL.Bind_Variable( curHandle, 'street', street ); end if; if postcode is not null then DBMS_SQL.Bind_Variable( curHandle, 'postcode', postcode ); end if; -- execute cursor (to create the cursor program) and pass it back as a ref cursor res := DBMS_SQL.Execute( curHandle ); refCur := DBMS_SQL.To_RefCursor( curHandle ); end; -

There might be a simpler and more efficient way in function your tables and your limit.
The condition u2.username = ' VALUEOF (NQ_SESSION. The USER) "almost certainly not what you really want.

[SQL] Where the problem of the clause with subqueries
Hello
I am writing a query for an apex application where I have a field (P47_UNNR) for filtering. In my where clause I try to do this:
... AND IN qo.pk_id
CASE
WHEN: P47_UNNR IS NULL
THEN
(SELECT pk_id FROM quote_orders)
ON THE OTHER
(SELECT QOR. FK_QUOTE_ORDER_ID
OF QUOTE_ORDER_RIDS QOR
JOIN THE
RID RID
WE RID. PK_ID = QOR. FK_RID_ID
WHERE RID.NAME LIKE: P47_UNNR)
END
...
But it gives an error "ORA-01427: einreihig subquery returns more than one line.
I tried several ways to work around this problem, but don't seem to be able to do. Does anyone have a suggestion on how to fix this?Try something like...
AND qo.pk_id IN (SELECT pk_id FROM quote_orders WHERE :47_UNNR IS NULL UNION ALL SELECT QOR.FK_QUOTE_ORDER_ID FROM QUOTE_ORDER_RIDS QOR JOIN RIDS RID ON RID.PK_ID = QOR.FK_RID_ID WHERE RID.NAME LIKE :P47_UNNR ) -

The problem is due to the "OR" condition (I did not pay attention to it earlier).
Because of this condition, your query is given beyond 7 days recovery. You need to rewrite the code as:
ALM_OG_CAMPAIGN_CODE in ('MED', 'MED1')Instead of
and ALM_OG_CAMPAIGN_CODE = 'MED' OR ALM_OG_CAMPAIGN_CODE = 'MED1';This will do the magic for you.

For UNION in VOImpl SQL WHERE clause
Hey gurus,
I need the ability to add a condition to VOImpl to user_id for two queries in a UNION statement. However, setWhereClause only adds condition at the end of the query. Any suggestions? I tried to make a selection online and could not because of the 'double '.
Thank you
-Scott
Select "Sys" x double where exists)
Select responsibility_name in the fur of fnd_user_responsibility,
fnd_responsibility_tl frt
When user_id = 16448
and frt.responsibility_id = fur.responsibility_id
and frt.responsibility_name = "system administrator")
Union
Select "NoSys" x double where does not exist)
Select responsibility_name in the fur of fnd_user_responsibility,
fnd_responsibility_tl frt
When user_id = 16448
and frt.responsibility_id = fur.responsibility_id
and frt.responsibility_name = "system administrator")You can have the condition at the request of origin itself and in the VOImpl, just switch the setting.
select 'Sys' x from dual where exists ( select responsibility_name from fnd_user_responsibility fur, fnd_responsibility_tl frt where user_id = :1 and frt.responsibility_id = fur.responsibility_id and frt.responsibility_name = 'System Administrator') union select 'NoSys' x from dual where not exists ( select responsibility_name from fnd_user_responsibility fur, fnd_responsibility_tl frt where user_id = :2 and frt.responsibility_id = fur.responsibility_id and frt.responsibility_name = 'System Administrator')See you soon

This means SQL executed in different order, or there is some reason to get error in that order?
Hello
Kimmy says:
HI Frank and Baris,
Is that means there is a defined order for execution of SQL to oracle but compiling the SQL statement has no order defined by the (FROM, WHERE, GROUP BY) clauses and compilation may give error in any order, and which will compile all first does matter?
Kind regards
The system can choose to compile an SQL statement in any order. I have never seen a case where this order is significant to anyone. (I don't know what is important to you.)
If your code has compile errors, you will get only 1 error message, and the message can be caused by any line of your code. If your SQL statement has 10 lines, and you get an error message referring to line 5, there may be other errors as well. If there is another error, could be on lines 1-4, or it could be on lines 6-10, it could be elsewhere on line 5.
There is a relationship between the clauses in your code and the order in which the code is run. For example, the compiled code corresponding to a condition of a FROM clause join will probably run before the compiled code corresponding to the ORDER byclause of this request. The rules specifying the 'order' can be useful, but should not be taken too literally.
