(view hint or Query writing method) using views in Select Query

Need Assistance,
Hi all,
My database having many views. while i am joining the views in a select query increase the cost of the querys due to the complex joins in the conditions.
While checking the select query with views individualy taking less cost.
Does any hint or query writing method is availabe to avoid the merging of the execution plan of the views?
I have browsed many related to the mentioned issues,couldn't found any thing that helps me.
Please help me on this issue,it will be very much helpfull for me.
Thanks,
Senthur

Please read the two threads linked to in the FAQ: {message:id=9360003} and post the relevant details they request, so that people can help you better with your issue.
We cannot help if you just say "my query is slow what do I do to fix it" as we cannot see your queries, your data, or any other information we would need to help. If the answer was that simple, it would be built into oracle so that the optimiser would fix it for you.

Hi,
I am attaching few threads.Hope these will help you.
If there are any error records in session, all those error records will get poulated in log .SM35 and after the session is completed , u can see error records which can be corrected and reprocessed again
We have the structures BDCLD and BDCLM, which will capture the log details inthe session. Firstly, sesssion should be processed. After that log will be created. Then caputure the information into an internal table using BDCLM and BDCLD.

Query: how to use structure and selection and what's the difference between

Query: how to use structure and selection and what's the difference between these two?
Would be appreciated if some experts here give examples to demenstrate on how to use structure and selection in query and what's the difference between these two?
Thanks in advance!

Hi Kevin,
1. Well by default all the KF that you include in your query go into a Key Figure Structure. You can additionally have another structure for defining how your chars are laid out. A common example is a Calmonth structure where you have selections for 12 months, quarers and YTD values. This would be a char structure with different selections (for each month, qtr etc)
2. Yes, a selection with a KF is the same as restricting a KF. You can use am RKF is you have one on the left hand side, or if you need to do this locally in the query, right click the structure and choose New Selection, then proceed to choose your KF and reqd char values.
Hope this helps...

How can i use index in select query.. facing problem with the select query.

Hi Friends,
I am facing a serious problem in one of the select query. It is taking a lot of time to fetch data in Production Scenario.
Here is the query:
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelat LEFT JOIN ztfzberep
     ON ztfzberep~gjahr = st_input-gjahr
     AND ztfzberep~poper = st_input-poper
     AND ztfzberepcntr = ztftelatrprctr
    WHERE rldnr = c_telstra_accounting
      AND rrcty = c_actual
      AND rvers = c_ver_001
      AND rbukrs = st_input-bukrs
      AND racct = st_input-saknr
      AND ryear = st_input-gjahr
      And rzzlstar in r_lstar
      AND rpmax = c_max_period.
There are 5 indices present for Table ZTFTELAT.
Indices of ZTFTELAT:
Name   Description
0        Primary key( RCLNT,RLDNR,RRCTY,RVERS,RYEAR,ROBJNR,SOBJNR,RTCUR,RUNIT,DRCRK,RPMAX)
005    Profit (RCLNT,RPRCTR)
1        Ledger, company code, account (RLDNR,RBUKRS, RACCT)
2        Ledger, company code, cost center (RLDNR, RBUKRS,RCNTR)
3        Account, cost center (RACCT,RCNTR)
4        RCLNT/RLDNR/RRCTY/RVERS/RYEAR/RZZAUFNR
Z01    Activity Type, Account (RZZLSTAR,RACCT)
Z02    RYEAR-RBUKRS- RZZZBER-RLDNR
Can anyone help me out why it is taking so much time and how we can reduce it ? and also tell me if I want to use index number 1 then how can I use?
Thanks in advance.

Hi Shiva,
I am using two more select queries with the same manner ....
here are the other two select query :
***************1************************
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelpt LEFT JOIN ztfzberep
     ON ztfzberep~gjahr = st_input-gjahr
     AND ztfzberep~poper = st_input-poper
     AND ztfzberepcntr = ztftelptrprctr
    WHERE rldnr = c_telstra_projects
      AND rrcty = c_actual
      AND rvers = c_ver_001
      AND rbukrs = st_input-bukrs
      AND racct = st_input-saknr
      AND ryear = st_input-gjahr
      and rzzlstar in r_lstar
      AND rpmax = c_max_period.
and the second one is
*************************2************************
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelnt LEFT JOIN ztfzberep
     ON ztfzberep~gjahr = st_input-gjahr
     AND ztfzberep~poper = st_input-poper
     AND ztfzberepcntr = ztftelntrprctr
    WHERE rldnr = c_telstra_networks
      AND rrcty = c_actual
      AND rvers = c_ver_001
      AND rbukrs = st_input-bukrs
      AND racct = st_input-saknr
      AND ryear = st_input-gjahr
      and rzzlstar in r_lstar
      AND rpmax = c_max_period.
for both the above table program is taking very less time .... although both the table used in above queries have similar amount of data. And i can not remove the APPENDING CORRESPONDING. because i have to append the data after fetching from the tables. if i will not use it will delete all the data fetched earlier.
Thanks on advanced......

How to use offset in select query

Suppose i have data like ssonje     00000001 as a one field in database table . i have to segregate this two data. how should I do this.the first part is of 12 characters and the last is of 10 character long.

Hi Naveen,
I am again in trouble, Now the requirement were changed. I am sending you the code which i had implemented.
Now, the user enter username(ie UNAMED) and document id (ie. TEMPD) and the output should be doucment id, which has been search through database table RFDT , field SRTFD, this field contains both the username and the document id.
That means: suppose user enters UNAMED as SSONJE and TEMPD as 0000000030, then i want to fier the select query from RFDT on field SRTFD and get only the document id of that user which user enter on input field-UNAMED.
i had tried but result were not coming.
please go through the code.
data:uname type UF05A-UNAMD.
data:temp type UF05A-TEMPD.
TYPES: BEGIN OF TEITAB_RFDT,
       SRTFD TYPE RFDT-SRTFD,
       END OF TEITAB_RFDT.
DATA: ITAB_RFDT TYPE TABLE OF TEITAB_RFDT.
DATA: WA_RFDT TYPE TEITAB_RFDT.
DATA: STR(22) TYPE c.
SELECT-OPTIONS:UNAMED FOR uname,
TEMPD FOR TEMP.
UNAMED-option = 'CP'.
append UNAMED.
CONCATENATE UNAMED TEMPD INTO STR.
SELECT SRTFD FROM RFDT INTO CORRESPONDING FIELDS OF TABLE ITAB_RFDT WHERE SRTFD eq str.
LOOP AT ITAB_RFDT INTO WA_RFDT.
SPLIT WA_RFDT AT SPACE INTO STR1 STR2.
WRITE: / STR1,STR2.
ENDLOOP.
Please mentioned what is the way to do this.
Thanks

But your script is not outputing the result of the query. So how do we view the returned resultset.

Using LIKE in Select query

Hi experts,
I am writing a Function module to get data from a table.
Import :
desc TYPE ZTABLE-DESCRIPTION.
Now when desc = te*
REPLACE ALL OCCURRENCES OF '*' IN
       desc WITH '%' .
SELECT *
    FROM ZTABLE
    INTO CORRESPONDING FIELDS OF TABLE t_list WHERE DESCRIPTION LIKE desc.
.. With is the table fetches all records where description starts with " te " .. here te is case senstive
So if description is "Test " or " TEST " or "tE" ......... so on.. i want this like to be made case in sensitive
Coz user can search as per his/her way...
Regards,
Bijal

e_sel-sign = 'I'.
e_sel-option = 'BT'.
e_sel-low = 'te%'.
e_sel-high = 'TE%'.
APPEND e_sel TO i_sel .clear e_sel.
e_sel-sign = 'I'.
e_sel-option = 'BT'.
e_sel-low = 'tE%'.
e_sel-high = 'Te%'.
APPEND e_sel TO i_sel .clear e_sel.
SELECT *
FROM ztable
INTO CORRESPONDING FIELDS OF TABLE t_list
WHERE description IN i_sel.
or
SELECT *
FROM ztable
INTO CORRESPONDING FIELDS OF TABLE t_list
WHERE description+0(2) in ( 'te%', 'TE%' , 'Te%', 'tE%').

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html
>> regarding the usecount column or any other column check this link:

Can we use Result from another query in Webi using Bex uery universe?

Hi,
Can we use Result from another query filter option in Webi to create a report using a Bex Query universe?
I need to create a report using two universes, one is Bex Query Universe and the other is Orcle universe. I have two queries, one is using Oracle universe; the other using Bex Query universe. I need to pass the Oracle data from the Oracle query to the Bex Query query to get the matched data from SAP Bex query.
I used Result from another query in the query filter panel for the query using Bex query universe. But I got an error saying that 'A filter contains a wrong value. you cannot run this query. (Error: WIS 00007). The data used in the filter on both sides are the same. they are char.
I have tested by using two queries from the same Bex query universe to see if the Result from another query filter option works. And I got the same error.
Has anyone run into the same issue and if this is possible and what should be the solution?
Thanks in advance!
Edited by: BO_Haiyan on Oct 6, 2010 3:47 PM

In that situation:
Create two queries : Oracle and BW query.
@ Report:
As you have to see result set from both the Dataproviders, correct? To achieve thise one must have common dimension objects to merge them at report and use Objects those are coming from both queries to use them in single Table/Report.
Unless you don't use Merge Dimensions, you don't get a chane to use both queries objects in single Table/Report. (It will give tooltip saying: You can't drop here -- Incompatable Objects)
In case, if you don't have common dimensions, change object definitions to Detail objects, for those required.
Hope it helps you.
Thank You!!

Concatenate results SQL query and CASE use Report Builder Reporting Services

I need to concatenate the results from a SQL query that is using CASE. The query is listed below. I do not need permitsubtype but I need to concatenate the results from the permittype.
I tried deleting the permitsubtype query and it would not run correctly. Please see the query and diagram below. Any help is appreciated.

  ISNULL(PERMITTYPE,'') = ''

  else (select LTRIM(RTRIM(PERMITTYPE)))
  END) AS PERMITTYPE

from Permit_Main
where ISSUED between @FromDate and @ToDate

Hi KittyCat101,
As per my understanding, you used case when statement in the query, you do not need to display permitsubtype in the report, but when you tried to delete permitsubtype from the query, it could not run correctly. In order to improve the efficiency of troubleshooting,
I need to ask several questions:
“I tried deleting the permitsubtype query and it would not run correctly.” As we can see, it has no effect to delete permitsubtype from the query you provided, could you please provide complete sql query for the report?
Could you please provide detailed information about the report? I would be appreciated it if you could provide sample data and screenshot of the report.
Please provide some more detailed information of your requirements.
This may be a lot of information to ask for at one time. However, by collecting this information now, it will help us move more quickly toward a solution.
Thanks,
Wendy Fu

Joining two tables having no common fields using one select query

Hi Experts,
How to join two tables which are NOT having any field in common using only one select query?
Your help will be appreciated.
Thank you.

Identify a third table (or more tables) with common fields with your two tables, or change your question either removing JOIN or removing NO COMMON FIELDS, else you wont get many responses and will be left alone in outer space, as suggested by Thomas.
If you acturally require what you written, better execute two select and merge the two internal tables merging every record from first table with every record of second table, til no more memory is available.

Raymond

SELECT Query design with JOINS

Dear Users,
In one of our requirements, we have a SELECT query which joins a few tables together and selects a few fields from each table.
Example: Fields 1,2 and 3 from Table 1
Fields 4 and 5 from Table 2.
These fields are later displayed in the form of an ALV. However, the end user wants more fields on the output, let's say field 6 from Table 2. Due to this requirement, I have to amend the SELECT query to add field 6 of Table 2.
The above example is simple since it only involves 2 tables. However, in reality, we have a SELECT query with INNER JOINS on more than 6 tables and we don't want to change the code when someone asks for an additional field from one of these tables. Is there any way by which I can design my SELECT query (Using field symbols or dynamic selections etc) such that I don't have to amend the SELECT query and instead I should be able to maintain the field required by the user and it's source table name in a Z-Table and the SELECT automatically picks it up ? Thanks!
Vijay

better you can create a view on your 6 or more tables and select the fields .
Use Select * from <view name> every time in a select statement.
If you need a additional column then just change the view , there is no need to change of your select query.
with regards

How to Run a Select Query stored in a Variable

Hello,
I have a following requirement:
Result of one select query on Var1 , result of other select query in Var2 ,
if Va2 = 'value11' OR Var2 = 'Value2' then Var1 = 'select query'. Now how can I run this SQL query at the end of the Pl/SQL?
so I'm writing following query for the same:
DECLARE
qry nvarchar2(500);
result nvarchar2(500);
BEGIN
select 'select TEXTVAL as "CHARG" FROM TABLE1 WHERE LOC =''[ParameterValue]'' and KEYNAME =''<<REPLACE>>''' INTO qry from dual;
SELECT CASE WHEN count(RW."CountofBATCH") > 1 then 'Mixing'
WHEN count(RW."CountofMAT") = 0 then 'None'
ELSE 'Other'
END
INTO result
FROM TABLENAME2 TT, XMLTable('/Rowsets/Rowset/Row' PASSING TT.XMLCOL
COLUMNS
"CountofBATCH" PATH '/Row[CLABS > 0]/CHARG',
"CountofMAT" PATH '/Row[MATNR = "[Parameter Value]"]/MAT'
) AS RW
where
TT.PL = '[Parameter Value]' and
TT.TANK = '[Parametr Value]' ;
IF result = 'Mixing' OR result = 'None' THEN
qry := replace( qry , '<<REPLACE>> ' , result);
else
qry := 'Nothing';
END IF;
This way the variable qry will have select statement. Now How can I run this qry variable to get the output of that select statement in the same query?

you can use execute immediate if the output of the query is in the single query.
that is very simple.
have the query in the signle string and then pass like this
declare
qry varchar2(255);
result varcharf2(2500);
vempid number :=1;
begin
qry:='select empname from emp where empid=:empid';
execute immediate qry into result using vempid;
-----now the data result is in result
end;

Select Query Resutls - operand for WebI Rich Client XI3.0 not available?

Hi ,
Using Deski we put a filter condition on a query using the deski query panel. Also we can select resutls from another query in the same report (query from a differen dataprovider) using the operand Select Query Resutls(any).
However in Web Intelligence Rich Client for XI3.0 we don't have this operand so we can not filter using results from another query in the same report.
Does anyone know how to work around this problem?
Know any plans for this feature ? As you all know, this is an extremely powerful feature.
Rgds,

Minkook,
Does anyone know how to work around this problem?
Rich client allows you to import a text or excel file on the fly to your report. To filter what you have you could build entries into the excel file, import, merge dimensions and voila, have your filtering done. It does seem dumb to do it this way when a quick filter is all you want. I'm with you in that the quick filter functionality would be highly desirable.
Thanks,
John

Problem with select query

Hi All,
i_dfkkko-xblnr
IF NOT i_dfkkko[] IS INITIAL       .
    SELECT opbel
           belnr
           FROM erchc
           INTO TABLE i_erchc1
           FOR ALL ENTRIES IN i_dfkkko
           WHERE opbel EQ i_dfkkko-xblnr.
ENDIF.
I am using the above select query.problem is when i put the value
of i_dfkkko-xblnr by going to the table erchc i am getting the record.But this qury is not resulting any value.
i have checked in debug mode copied the value of xblnr of i_dfkkko
and went to erchc table and passed to opbel of erchc i got the reords.
can anybody pls help..
Rgds,
Sai

Hi,
The database would be having the value with leading zeroes.
Use FM "CONVERSION_EXIT_ALPHA_INPUT" to conver the values & then pass to select query.
_dfkkko-xblnr
IF NOT i_dfkkko[] IS INITIAL .
loop at i_dfkkko.
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
EXPORTING
VALUE(INPUT) = i_dfkkko-xblnr
IMPORITNG
VALUE(OUTPUT) = i_dfkkko-xblnr.
modify i_dfkkko.
endloop.
SELECT opbel
belnr
FROM erchc
INTO TABLE i_erchc1
FOR ALL ENTRIES IN i_dfkkko
WHERE opbel EQ i_dfkkko-xblnr.
ENDIF.
