Query related to excution and performance of count in select statement

Hi,
What are the difference between
select count(1) from table
and
select count(*) from table

Thanks for the reply.I searched lots of thread for the same and found that it's same (excution wise and performance wise).
But in few thread i found that someone is saying
"At the time of exceution Count(1) will conevrted internally to count(*) " --- is it correct
"is there any soecial significance of using count(42)" ?
Tx,
Anit

Query to find first and last call made by selected number for date range

Hi,
query to find first and last call made by selected number for date range
according to filter:
mobile_no : 989.....
call_date_from : 25-april-2013
call_date_to : 26-april-2013
Please help

Hi,
It sounds like you want a Top-N Query , something like this:
WITH    got_nums   AS
     SELECT     table_x.*     -- or list columns wanted
     ,     ROW_NUMBER () OVER (ORDER BY call_date      ) AS a_num
     ,     ROW_NUMBER () OVER (ORDER BY call_date DESC) AS d_num
     FROM     table_x
     WHERE     mobile_no     = 989
     AND     call_date     >= DATE '2013-04-25'
     AND     call_date     < DATE '2013-04-26' + 1
SELECT *     -- or list all columns except a_num and d_num
FROM     got_nums
WHERE     1     IN (a_num, d_num)
;This forum is devoted to the SQL*Plus and iSQL*Plus front ends. This question doesn't have anything to do with any front end, does it? In the future, you'll get better response if you post questions like this in the PL/SQL.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Joins And For all Enteries in Select Statement

Could you please tell me when there is a high amount of data which is being handled in the table, does the use of INNER JOINS and FOR ALL ENTERIES in SELECT Statement decreases the system performance? ?
Can you also let me know where can i get some tips regarding do's and dont's for ABAP Programming, I want to increase my system performance.
Currently the programs which are being used are taking a lot of time for execution...
Its very URGENT!

Hai Jyotsna
Go through the following Tips for improving Performence
For all entries
The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the length of the WHERE clause.
The plus
Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
               FOR ALL ENTRIES IN i_tab
                  WHERE mykey >= i_tab-low and
             mykey <= i_tab-high.
Nested selects
The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:
Large amount of data
when mixed processing isnt needed
Performance killer no. 1
Select using JOINS
The plus
Very large amount of data
Similar to Nested selects - when the accesses are planned by the programmer
In some cases the fastest
Not so memory critical
The minus
Very difficult to program/understand
Mixing processing and reading of data not possible

Optimizing the load of the database
Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a statement can not be used with a buffered table, so when using these statements the buffer will be bypassed. These statements are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clause that contains a sub query or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wan t to explicitly bypass the buffer, use the BYPASS BUFFER addition to the SELECT clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The database server will usually be the bottleneck, so sometimes it is better to move the sort from the database server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT statement to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the database server sort it.
Avoid the SELECT DISTINCT Statement
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplicate rows.

Count(*) in select statement having group by clause

Hi
I would like to use count(*) in select statement having group by clause. say for example there is a state with a number of cities listed. I would like to get the count of cities for each state.
the sql stement is grouped by city and it is joined with 5 more tables.
Thanks

I suspect you want to look into analytic functions (assuming you have a recent version of Oracle). asktom.oracle.com has numerous examples if you do a search.

BPEL function to query the Element Name and get the count of elements

Hi Guys,
I have problem with the following, can you please help me out with this.
Say i have an xml pay load:
<ns1:sampleEBO>
               <ns1:PhysicalLocation>
               <ns1:propertis>
                    <ns1:filedType>12</ns1:filedType>
                         <ns1:filedType1>12</ns1:filedType1>
                         <ns1:filedType2>12</ns1:filedType2>
<ns1:filedType3>12</ns1:filedType3>
                         <ns1:filedType4>12</ns1:filedType4>
                         <ns1:filedType5>12</ns1:filedType5>

               </ns1:properties>
<ns1:sampleEBO>
               <ns1:PhysicalLocation>
Here i want to retrive the Element name ( filedType,fieldType1,fieldType2......) using any BPEL function, not the value and also get the total number of elements in the each node ( <properties> ). If i am using the "count" function its returning 2 and it's counting the properties node not the elements in the properties node.
So, can you please let me know of any function in BPEL which can do this ?
Thanks,
Krish

you only want to use a default bpel function for this? not from within xsl?
and the function should return an arraylist of elementnames i assume ?
               <xsl:for-each select="//properties">
                    <xsl:for-each select="./*">
                         <xsl:value-of select="local-name()"/>
                         <xsl:choose>
                              <xsl:when test="substring(local-name(),1,9) ='filedType' ">
                         </xsl:when>
                         </xsl:choose>
                    </xsl:for-each>
               </xsl:for-each>
               <count1><xsl:value-of select="count(//properties[1]/*)"/></count>
               <count2><xsl:value-of select="count(//properties[2]/*)"/></count>the count can also be used in some for-each construction or from within your bpel flow itself (if you want to loop over there, instead of xsl)

MRP query related to MTO and MTS

Dear Gurus,
I have got 2 Plants.......Plant A(Manufacturing Plant) and Plant B (Selling Plant)
My scenario is Make to Order, where the sales order is getting created in Plant B(selling Plant) for Export Material
1)when I run the MRP for Export material by MD50 ......Planned order should be created in Plant A and it should show in MD04 screen then only I can convert that planned order into production order.
2) After confirmation of that order and after GR.....stock should go to Plant B so that SD person will deliver that stock to the respected customer.
3)when I run the MRP by MD50, in the material BOM.....if any shortage of RAW MATERIAL OR PACKING MATERIAL then collective PR should be created in Plant B(selling plant).
what setting we should maintain in Meterial master related to PP for all raw/packing/semifinish/finish materials in both the plants related to MTS and MTO?
Could you provide me solution for the above queries.
Max

Dear
This can be achieved by using special procurement type (80 production in another plant) in all production master data (material master for inhouse production, BOM, Routing and production version) will be made in plant B and in plant A same material will have material master for MRP i.e. MRP group, MRP type MRP controller Procurement type special procurement (80) in MRP2 production storage location, planning strategy etc.
you can see in MD04 for plant B delivery plant will be A. and in MD04 for plant A planning plant B.
production order will be confirmed in plant A and GR will be done in Plant B.
and purchase requisitions for component will be raised from plant A. if all components are required to be procured in plant B, all component will have also special procurement either 40 Stock transfer (proc.from alter.plant)
or 70 Withdrawal from alternative plant.
I hope this will solve your issue. Kindly let me know if your issue will solved or not.
Thanks

Increase performance of the following SELECT statement.

Hi All,
I have the following select statement which I would want to fine tune.
CHECK NOT LT_MARC IS INITIAL.
SELECT RSNUM
         RSPOS
         RSART
         MATNR
         WERKS
         BDTER
         BDMNG FROM RESB
                      INTO TABLE GT_RESB
                      FOR ALL ENTRIES IN LT_MARC
                      WHERE XLOEK EQ ' '
                      AND MATNR EQ LT_MARC-MATNR
                      AND WERKS EQ P_WERKS
                      AND BDTER IN S_PERIOD.
The following query is being run for a period of 1 year where the number of records returned will be approx 3 million. When the program is run in background the execution time is around 76 hours. When I run the same program dividing the selection period into smaller parts I am able to execute the same in about an hour.
After a previous posting I had changed the select statement to
CHECK NOT LT_MARC IS INITIAL.
SELECT RSNUM
         RSPOS
         RSART
         MATNR
         WERKS
         BDTER
         BDMNG FROM RESB
                      APPENDING TABLE GT_RESB PACKAGE SIZE LV_SIZE
                      FOR ALL ENTRIES IN LT_MARC
                      WHERE XLOEK EQ ' '
                      AND MATNR EQ LT_MARC-MATNR
                      AND WERKS EQ P_WERKS
                      AND BDTER IN S_PERIOD.
ENDSELECT.
But the performance improvement is very negligible.
Please suggest.

Karthik

Hi Karthik,
<b>Do not use the appending statement</b>
Also you said if you reduce period then you get it quickly.
Why not try dividing your internal table LT_MARC into small internal tables having max 1000 entries.
You can read from index 1 - 1000 for first table. Use that in the select query and append the results
Then you can refresh that table and read table LT_MARC from 1001-2000 into the same table and then again execute the same query.
I know this sounds strange but you can bargain for better performance by increasing data base hits in this case.
Try this and let me know.

Hi Karthik,

Database adapter and column aliases in the select statement (10.1.3.1)

Hi,
Is it possible to use column aliases in the select statement for a database adapter to return an xml element name which is different to the column in the queried table?
I have tried using
SELECT EMPLOYEE_ID, FIRST_NAME AS MYNAME, LAST_NAME, SALARY, DEPARTMENT_ID, PHONE_NUMBER, EMAIL, HIRE_DATE FROM HR.EMPLOYEES WHERE (DEPARTMENT_ID = #DEPT_ID)
but I get the following XML fragment returned
<Employees>
<employeeId>100</employeeId>
<firstName xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
<lastName>King</lastName>
<salary>24000</salary>
Any pointers appreciated.
Joel.

That is really interesting.
When I use the "custom sql" option in the DB adapter wizard, it used the aliases just fine in the return schema.

--order by c001However this approach yields this error when I try to pick a value from the lov:
Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus.
My other approach is to attempt to change the type and class in javascript. I am trying this but I get an error when I attempt to change the class and type like this:
<script type="text/javascript">

</script>

not completely duplicate...here in this thread I am stressing what I am trying to accomplish and asking for help on the javascript side.

Performance problem of asset selection statement.

Hi guys quick question.
SELECT a~bukrs
           a~anln1
           b~anln2
           a~anlkl
           a~aktiv
           a~txt50
           a~lvtnr

           INTO TABLE it_anla
           FROM anla AS a
           INNER JOIN anlb AS b
           ON a~bukrs EQ b~bukrs
           AND a~anln1 EQ b~anln1
           WHERE a~bukrs IN s_bukrs
           AND a~anln1 IN s_anln1
           AND a~anln2 EQ '0000'
           AND a~anlkl IN s_anlkl
           AND a~aktiv EQ '00000000'
           AND a~lvtnr IN s_lvtnr
           AND b~afabe EQ 01.
I have a select statement which is filtered by capitalization date which is the field AKTIV. This select alone has 450 thousand hits. Having an ANLN2 = 0 and AKTIV = blank/no date means that the asset group is no longer active.
Now for another scenario I have to retrieve table ANLA again excluding all the Main Asset Number/ANLN1 found on that table.
Is there a way to select by doing it only once?
I tried to pass all the anln1 to a range table but the program dumps. I think the range table can't handle too many entries.
Retrieving all the entries from the DB then processing it takes longer.
I tried to delete the table using a loop but it takes to long as it process the table every loop.
LOOP AT it_anla WHERE anln2 EQ '0000' AND aktiv EQ '0000000'.
      DELETE it_anla WHERE bukrs EQ it_anla-bukrs AND anln1 EQ it_anla-anln1.
    ENDLOOP.
Thanks.

If the range table for anln1 is large and contains distinct values, you can try using it in a FOR ALL ENTRIES construct rather than IN.

Query related to write() and setsockopt()

Hi ,
This query is based on Solaris10. I will just brief out the issue and also the information which I am seeking. Here I am creating a TCP socket, and then increasing the socket buffer by using setsockopt(). Here is the call "setsockopt(fd, SOL_SOCKET, SO_SNDBUF,&txBufSize, sizeof(txBufSize))" . Here txbufsize is nothing but an integer that has a value equal to 65536.
Here I am writing some data by using the write system call like "write(fd, (char*) pData, (int) length));" Here The logic is to write to the socket fd, by using the above write () the pData of length 204 bytes continously for 40 times in a second. That means in a second maximum possibility of writing to the socket buffer is 204*40 ie. 8160 bytes.
The issue is after writing 8 to 9 times, that is after a successful write of around 1836 bytes of data (9 times * with 204 bytes each), write is failing with an error number "EWOULDBLOCK". The man page is giving an information that error code indicating that there is no free room available in the socket transmit buffer. But as I said earlier the buffer which I send so far is only 1836 bytes, also the socket buffer which I have allocated by using 'setsockopt' is 65536 which is much higher value.
Here what I am looking for is two things.
1. Does anybody has any insight why this write() is failing with EWOULDBLOCK, the same code was working fine in Solaris 8 as well as in 9. The same code is recently ported to Solaris10. This behaviour is observed only in Solaris10.
2. Is there any way I can debug how much buffer is already written or how much buffer is still free to use for writing, before I initiate a write(). It would be really great if anyone can point out a debugging tool or is there any way I can instrument the code with proper logs to print out the buffer each time before the write() call.
Thanks,
Sree

Actually, there was a typo in the bigAdmin article. The tunable parameter in question is actually called
tcp_fusion_rcv_unread_min
and is set in /etc/system as follows:
set ip:tcp_fusion_rcv_unread_min=0
The parameter description is:
This is the minimum amount of outstanding writes allowed on a synchronous streams-enabled receiving endpoint before the sender gets flow-controlled. Setting this value to 0 means that the data block limit is equivalent to the byte count limit, which essentially disables the check. Flow control for TCP fusion in synchronous stream mode is achieved by checking the size of receive buffer and the number of data blocks, both set to different limits. This is different that regular stream flow control. The need for this limit is to ensure that the sending and receiving processes are both getting the resources they need to process the data and that neither is starving the other.

A query related to ProgressBar and its placing inside Container

Hi ,
I tried an example with Flex3 ProgressBar .I am posting the scenario in which it was correct in one case and wrong in another case .
Please tell me what is wrong here in the wrong case :
The Program is related to :
I have button on click of that i will be loading the Image . There is no Button and its event Listener Mentioned here .
Correct Approach :
This works fine as the Image and ProgressBar are in the same Container called HBox
<mx:HBox>
<mx:Image id="image" autoload="false"/>
<mx:ProgressBar id="MYPB" source="{image}"/>
</mx:HBox>
Wrong Approach :
The below isn't working as i placed ProgressBar outside the container called as HBox
<mx:HBox>
<mx:Image id="image" autoload="false"/>
</mx:HBox>
<mx:ProgressBar id="MYPB" source="{image}"/>
Please share your ideas as why this behaves this way .

Hi Kiran.
I don't think either of the approach is wrong , it no way effected by placing the ProgressBar inside a container or outside the container.
Run the sample application below. It will load for both approaches.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">
<mx:Script>
        <![CDATA[
            public function loadImage1():void {
              image1.load('assets/liazon_logo.png');
            public function loadImage2():void {
              image2.load('assets/liazon_logo.png');
        ]]>
    </mx:Script>
<mx:HBox>
<mx:Image id="image1" autoLoad="false"/>
</mx:HBox>
<mx:ProgressBar id="MYPB1" source="{image1}"/>
<mx:Button label="Load Image1" click="loadImage1()"/>
<mx:HBox>
<mx:Image id="image2" autoLoad="false"/>
<mx:ProgressBar id="MYPB2" source="{image2}"/>
</mx:HBox>
<mx:Button label="Load Image2" click="loadImage2()"/>
</mx:Application>

Output count of SELECT statement is diff from count(*) of the same query

Has this ever happened to you?
I was wondering why some of the items were not appearing in my output. I have this select query:
    SELECT
        bukrs
        gjahr
        hkont
        belnr
        wrbtr
        dmbtr
        matnr
        bschl
        kunnr
        vbeln
        shkzg
    FROM bseg
    INTO CORRESPONDING FIELDS OF TABLE i_output
    FOR ALL ENTRIES IN i_bkpf
    WHERE
        bukrs EQ i_bkpf-bukrs
        AND belnr EQ i_bkpf-belnr
        AND gjahr EQ i_bkpf-gjahr
        AND hkont IN hkont
        AND hkont IN
            ('0004000000',
            '0004000010',
            '0004000020',
            '0004000030',
            '0004000040')
When I tried to put sample filters (bukrs: 1000; belnr 1800000016; gjahr: 2005; hkont: 4000000), I am getting 3 entries from bseg. But when I tried using SE16 or SE16N, I am getting 6 (which is the expected output). When I modify the same SELECT query to return just the output count, I AM getting 6.
    SELECT count(*)
    FROM bseg
    INTO count
    FOR ALL ENTRIES IN i_bkpf
    WHERE
        bukrs EQ i_bkpf-bukrs
        AND belnr EQ i_bkpf-belnr
        AND gjahr EQ i_bkpf-gjahr
        AND hkont IN hkont
        AND hkont IN
            ('0004000000',
            '0004000010',
            '0004000020',
            '0004000030',
            '0004000040')
Do you have any idea why this happens? My internal table is a standard table with no header line and no OCCURS statement.
Kyle

Hello Kyle,
Thats because when using FOR ALL ENTRIES, it will delete the duplicates if the records selected dont have all the primary keys specified in the select query. In your first select query, the field BUZEI is missing which makes the records unique. Change your first select query as this and try
SELECT
        bukrs
        gjahr
        hkont
        belnr
        buzei   -------> Add this and check
        wrbtr
        dmbtr
        matnr
        bschl
        kunnr
        vbeln
        shkzg
    FROM bseg
    INTO CORRESPONDING FIELDS OF TABLE i_output
    FOR ALL ENTRIES IN i_bkpf
    WHERE
        bukrs EQ i_bkpf-bukrs
        AND belnr EQ i_bkpf-belnr
        AND gjahr EQ i_bkpf-gjahr
        AND hkont IN hkont
        AND hkont IN
            ('0004000000',
            '0004000010',
            '0004000020',
            '0004000030',
            '0004000040')

Help with a query using ISNULL and RTRIM in the same select statement

What I'm trying to accomplish is to blend the following two statements together:
ISNULL (EMail_Address, '') As Matrix_Member_Email
AND
RTRIM (EMail_Address) as Matrix_Member_EMail
So that if the email address is NULL, it gets changed to blank and I still need to RTRIM the other entries and use the column header of Matrix_Member_Email.
I've tried:
ISNULL ((EMail_Address, '') (RTRIM (EMail_Address)) as Matrix_Member_EMail
Any help would be greatly appreciated.
Thank you,

I'm sorry. Here is the query:
--Declare @EMail_Address nvarchar(100) = null
Select SVAssociationID.R_ShortValue as MATRIX_AssociationID, Matrix_Modified_DT as Matrix_LastModified
  ,RTRIM (MLS_ID) As Matrix_MLS_ID
  , ISNULL(EMail_Address, '') AS MATRIX_member_Email
  ,RTRIM (EMail_Address) as Matrix_Member_EMail
  --,RTRIM( LTRIM( ISNULL (@EMail_Address, '') ) ) as Matrix_Member_EMail
  ,Last_Name AS MATRIX_LastName, Nickname AS MATRIX_NickName
  FROM    dbo.Agent_Roster_VIEW a
        LEFT JOIN dbo.select_values_VIEW SV ON a.Status_SEARCH = SV.ID
        LEFT JOIN dbo.select_values_VIEW BillType ON a.Bill_Type_Code_SEARCH = BillType.ID
  LEFT JOIN dbo.select_values_VIEW SVAssociationID ON A.Primary_Association_SEARCH = SVAssociationID.ID
WHERE   Status_SEARCH IN (66,68)
    Order by MLS_ID
Results:
MATRIX_AssociationID
Matrix_LastModified
Matrix_MLS_ID
MATRIX_member_Email
Matrix_Member_EMail
MATRIX_LastName
MATRIX_NickName

Performance issue on a select statement

Hi all @ SAPforums and thanks for your attention,
the task is quite simple: given a Purchase Requisition number and position (banfn, bnfpo) I have to check if a contract with the same PR as source exists in the EKPO table.
In order to check for it, I simply typed the following select:
SELECT SINGLE * FROM EKPO INTO wa_checkekpo
      WHERE bstyp EQ 'K'
        AND banfn EQ l_eban-banfn
        AND bnfpo EQ l_eban-bnfpo.
This kind of query is quite consuming (more than three seconds in my process) due to the fact that banfn and bnfpo don't belong to a key for the table.
Any idea/workaround that can lead to better performance? Please note I'm not interested in retrieving the contract number (KONNR), it's sufficient to know it exists.

Hi,
> Do not use select * if you just want to check existence of the record.
so far so good.
> Use a single variable to store teh count.
But why should we count the records if we just want to know if a key exists in
the db or not? change the second half of the recommendation to:
Use a single field of the used index for the select list to check (sy-subrc or result
of that field) if the record exists or not.
Kind regards,
Hermann
