Help in below query

Hi ,
SELECT wip_entity_name , pr_coc
FROM AEC.COC
WHERE WIP_ENTITY_NAME in (
'NP127408',
'NP127409',
'NP127407',
'NP127406')
Now the result I want is even if the wip_entity_name is not in the table the qry should return the wip_entity_name and pr_coc as a null along with normal result.
Thanks

Hello India :-)
Actually Toronto is the city where I live, my name is john.
If y ou have thousands of rows in an Excel spreadsheet, you are going to have to load them into the database (or at least make them accessible to the database) before you can use them for a query.
The simplest way, particularly if this is a one time shot. would be to use a formula in Excel to generate the insert statements, then copy the generated insert statements to the database server as a text file and then run it is sqlplus. Make sure that you do ALTER SESSION SET CURSOR_SHARING = FORCE before running those insert statements.
Then run my outer join query, replacing the WITH clause with your loaded table.
So, assuming you inserted the jobs into a table called excel_jobs, then the statement would be something like:
SELECT ej.wip_entity_name, coc.coc
FROM excel_jobs ej
   LEFT JOIN coc ON el.wip_entity_name = coc.wip_jobs;HTH

    You can't use 'c_rank' in the where clause because it doesn't exist; you are computing it in the SELECT clause.
    Remove the last condition and wrap your query in another one to select by 'c_rank'.

  • Help needed in query optimization.....

    Hi
    I have this below query which automatically gets generated in siebel.
    Problem is when i execute this query in toad for "Nichole" it took 2 mins to return 30 records but when i execute this same query for "Adam" it returns more records than Nichole and return results in 1-2 secs. i Know executing query in toad is not a proper way but this below query will get executed in same way thru siebel application. Histogram is already created on column "Name" but of no help. Composite Index(CX_AA_EVNT_RADIO_BATCH_TIME) is there on column bot_id & timestp.
    Table s_org_ext has only 5 records of "Nichole" and 10 records of "Adam".
    Will including Column "Name" in Above composite index can help?
    Please anybody can suggest me anything in this? whatelse i can do to tune this query?
    Thanks for your help in advance

    Thanks in advance.

    Hi,
    If you want all the rows from goh, then you don't want any conditions like  goh.OFFER_NO <> 0.
    Make all the joins to goh outer joins, and make all conditions that apply to any tables joined to goh (or to tables joined to them) part of the join condition, like this:
    FROM             APPS_JP.GEDIS_OFFER_HEADER     goh
    LEFT OUTER JOIN  APPS_JP.GEDIS_ORDER_BUILDS     gob  ON   gob.OFFER_NO = goh.OFFER_NO
                                                         AND  gob.BUILD_NO = 1
    LEFT OUTER JOIN  APPS_JP.GEDIS_ORDER_LINES      gol  ON   gol.OFFER_NO = goh.OFFER_NO
                                                         AND  gol.BUILD_NO = 1
                                                         AND  gol.LINE_NO  = 1
    LEFT OUTER JOIN  APPS_JP.GEDIS_OFFER_RELATED_CUSTOMER
                                                    gorc ...
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
    Simplify the problem as much as possible.  For example, do you really need all those tables to show what the problem is?  Of course, you need them in tyour real query, but if you understand a solution that only involves 4 or 5 tables, you'll know how to apply it to any number of tables.
    Explain, using specific examples, how you get those results from that data.Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

  • Need a help in SQL query

    Hi,
    I need a help in writing an SQL query . I am actually confused how to write a query. Below is the scenario.

      org_id   NUMBER,
      order_line_id NUMBER,
      quantity NUMBER,
      order_type NUMBER

       open_flag  VARCHAR2(10)
    INSERT INTO demand_tmp
    SELECT 12438,82,821,100,30 FROM dual;
    INSERT INTO demand_tmp
    SELECT 12438,82,849,350,30 FROM dual;
    INSERT INTO demand_tmp
    SELECT 12438,82,NULL,150,29 FROM dual;
    INSERT INTO demand_tmp
    SELECT 12438,82,0,50,-1 FROM dual;
    INSERT INTO order_tmp
    SELECT 12438,82,821,'Y' FROM dual;
    INSERT INTO order_tmp
    SELECT 12438,82,849,'N' FROM dual;

    12438     82                  849                N     I need to fetch the records from demand_tmp table whose order_line_id is present in order_tmp and having open_flag as 'Y' or if order_type in demand_tmp table is 29.
    The below query will give the records whose order line id is present in order_tmp. But, If i need records which are having order_type=29 the below query wont return any records as order_line_id is NULL. If I place outer join I will get other records also (In this example order_type -1 records) . Please help me how can we write a query for this. Expected o/p is below.
    Query :
    Select item_id,org_id,order_line_id,quantity,order_type,open_flag
    from demand_tmp dt , order_tmp ot
    where dt.order_line_id = ot.order_line_id
    AND dt.item_id=ot.item_id
    AND dt.org_id = ot.org_id
    AND ot.open_flag = 'Y';
    Expected Output :                         
    item_id     org_id     order_line_id     quantity     order_type   open_flag
    12438     82                 821               100                    30             Y
    12438     82              NULL               150                29         NULL Thanks in advance,

    Hi Rakesh,
    the query is not working as you would like ( but IS working as expected ) since your trying to compare null to another value.
    Comparing null always results in FALSE, also if you compare null to null. This is because null means undefined.
    select 1 from dual where null=null results in no data found.
    I would suggest using a non natural key to join the tables.
    For example include a column ID in the master table which is filled with a sequence and include that field as a foreign key in the detail table.
    This way you can easily join master and detail on ID = ID, and you don't have to worry about null values in this column since it's always filled with data.
    Regards,
    Bas
    btw, using the INNER JOIN and OUTER JOIN syntax in your SQL makes it better readable, since you're separating join conditions from the where clause, just a tip ;)

  • Help with my query

    Hello all,
    Total newbie to this pl/sql stuff. So, deseperately need help in my query.
    BOOKING_ID     BOOKING_STATUS     BOOKING_DATE     BOOKING_TIME     BOOKING_DATE_TIME
    1234567     CANCELLED     20090301     37252     5/1/2010 10:20
    1234567     CANCELLED 20090301     44229     5/1/2010 12:17
    1234567     BOOKED     20090301     39462     5/1/2010 10:57
    1234567     CANCELLED     20090301     43549     5/1/2010 12:05
    9671111     BOOKED     20090301     68124     5/1/2010 12:57
    9671111     CANCELLED     20090301     45001     5/1/2010 12:05
    How do I write my query such that I would get the following results:
    BOOKING_ID     BOOKING_STATUS     BOOKING_DATE     BOOKING_TIME     BOOKING_DATE_TIME
    9671111     BOOKED     20090301     68124     2/4/2010 12:17
    Basically, I am looking at the latest BOOKING_TIME and making sure the BOOKING_STATUS=BOOKED, if not, don't even bother bring back the result. Hence, you see that BOOKING_ID=1234567 is not required since at the latest BOOKING_TIME=44229, the BOOKING_STATUS=CANCELLED.
    Any help is greatly appreciated.
    Thank you in advance for your help.
    Stanley Ho

    Hi, Stanley,
    Welcome to the forum!
    Whenever you have a question, please post your sample data in a form that people can actually use. CREATE TABLE and INSERT statements are perfect.
    For example:
    CREATE TABLE     booking
    (     booking_id          NUMBER (8)
    ,     booking_status          VARCHAR2 (10)
    ,     booking_date_time     DATE
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (1234567,        'CANCELLED',        TO_DATE ('5/1/2010 10:20', 'MM/DD/YYYY HH24:MI'));
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (1234567,        'CANCELLED',        TO_DATE ('5/1/2010 12:17', 'MM/DD/YYYY HH24:MI'));
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (1234567,        'BOOKED',        TO_DATE ('5/1/2010 10:57', 'MM/DD/YYYY HH24:MI'));
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (1234567,        'CANCELLED',        TO_DATE ('5/1/2010 12:05', 'MM/DD/YYYY HH24:MI'));
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (9671111,        'BOOKED',        TO_DATE ('5/1/2010 12:57', 'MM/DD/YYYY HH24:MI'));
    INSERT INTO  booking (booking_id, booking_status, booking_date_time)
                  VALUES (9671111,        'CANCELLED',        TO_DATE ('5/1/2010 12:05', 'MM/DD/YYYY HH24:MI'));What you want is called a Top-N Query .
    Here's one way to do it:
    WITH     got_rnum  AS
         SELECT     booking.*
         ,     ROW_NUMBER () OVER ( PARTITION BY  booking_id
                                   ORDER BY          booking_date_time     DESC
                           ) AS rnum
         FROM    booking
    SELECT     booking_id
    ,     booking_status
    ,     TO_CHAR (booking_date_time, 'YYYYMMDD')               AS booking_date
    ,     TO_CHAR (booking_date_time, 'SSSSS')               AS booking_time
    ,     TO_CHAR (booking_date_time, 'MM/DD/YYYY HH24:MI')     AS booking_date_time
    FROM     got_rnum
    WHERE     rnum          = 1
    AND     booking_status     = 'BOOKED'
    ;Notice that you don't need PL/SQL to do this; plain old SQL is good enough.
    Of course, if you're using PL/SQL for other reasons, you can use a query like this within PL/SQL.
    Dates (including time of day) should always be stored in DATE columns.
    If you have a DATE column, like booking_date_time, then there's no need for redundant date and time columns.
    You can always display just the year-month-day, or just the time, in any format, as I did above.
    The output from the query above, with the data above, is:
    BOOKING_ID BOOKING_ST BOOKING_ BOOKI BOOKING_DATE_TIM
       9671111 BOOKED     20100501 46620 05/01/2010 12:57I realize the booking_date and booking_time columns aren't quite what you posted. If they are not derivable from booking_date_time, then you probably do need separate columns for them, and those columns can easily be added to the query above.
    Edited by: Frank Kulash on Feb 5, 2010 4:41 PM
    KEEP (DENSE_RANK ...) , like Max used below, is a great tool to have in your kit. The problem with it is that you have to repeat a lot of stuff for every column, so the more columns you have in your output, the more tedious it gets. ROW_NUMBER sclaes much better, and is adaptable to more situations. I suggest you master ROW_NUMBER first, and look into KEEP (DENSE_RANK ...) later.

    Can you please post the following scripts:
    1. Tables structure (with all indexes & constraints)
    2. Tables data
    3. SQL trace file
    possibly everything that one can need to regenerate the scenario on his own DB...
    OR
    spend some time with Oracle Docs on Performance Tuning and then resolve it yourself.

  • Need help with this query

    Hi,
    I am using SQL Server 2008 Enterprise edition 64 bit on Windows serer 2008 enterprise edition 64 bit.
    The below query works fine. I am trying to rewrite the code without using the sub query. In the end i should get the same results for both the query which we are going to rewrite and the below mentioned query.
    Can any help me please.
    SELECT
    t1.DOCUMENT_NO,
    RTRIM(CAST(t1."ENVIRONMENT_CD" AS VARCHAR(5))) + '*' + RTRIM(CAST(t1."ORDER_NO" AS VARCHAR(25)))
    +
    CASE WHEN (SELECT COUNT(DISTINCT S1.TEST_REPORTING_MATERIAL_SID)
    FROM dbo.TBLTEST S1 ON S1.DOCUMENT_NO = T1.DOCUMENT_NO
    WHERE S1.TEST_REPORTING_MATERIAL_SID > 0
    AND S1.COMPANY_CD = T1.COMPANY_CD AND S1.INVOICE_SEQ_NO = T1.INVOICE_SEQ_NO
    AND S1.DOCUMENT_ITEM_NO = T1.DOCUMENT_ITEM_NO
    AND S1.ORDER_NO = T1.ORDER_NO) > 1 THEN
    RTRIM(CAST(t1."TEST_REPORTING_MATERIAL_SID" AS VARCHAR(10)))
    ELSE
    END as sum_key,
    t1.SALES_ANALYSIS_CD
    FROM
    dbo.TBLTEST_ALL T1
    WHERE
    t1.TIME_SID >= 20001001 ;
    I tried to use a left outer Join , it did not work out. I tried to take the subquery and assign it to a variable and use in the above mentioned query. But i am not getting the same results.
    I don't want to use the above query so i am planning to rewrite the code.
    Thank You,

    I doubt that the query you posted works fine, because:
    FROM dbo.TBLTEST S1 ON S1.DOCUMENT_NO = T1.DOCUMENT_NO
    This is a syntax error. I will have to assume that your inteded query reads:
    SELECT t1.DOCUMENT_NO,
           rtrim(cast(t1."ENVIRONMENT_CD" AS varchar(5))) + '*' +
           rtrim(cast(t1."ORDER_NO" AS varchar(25))) +
          CASE WHEN (SELECT COUNT(DISTINCT S1.TEST_REPORTING_MATERIAL_SID)
                     FROM   dbo.TBLTEST S1
                     WHERE  S1.DOCUMENT_NO = T1.DOCUMENT_NO
                       AND  S1.TEST_REPORTING_MATERIAL_SID > 0
                       AND  S1.COMPANY_CD = T1.COMPANY_CD
                       AND  S1.INVOICE_SEQ_NO = T1.INVOICE_SEQ_NO
                       AND  S1.DOCUMENT_ITEM_NO = T1.DOCUMENT_ITEM_NO
                       AND  S1.ORDER_NO = T1.ORDER_NO) > 1 THEN
                     RTRIM(CAST(t1."TEST_REPORTING_MATERIAL_SID" AS VARCHAR(10)))
               ELSE  '*-'
          END as sum_key, t1.SALES_ANALYSIS_CD
    FROM   dbo.TBLTEST_ALL T1
    WHERE  t1.TIME_SID >= 20001001
    Here is a query with a left join. Whether it is actually better than the one you have I am not sure.
    SELECT t1.DOCUMENT_NO,
           rtrim(cast(t1."ENVIRONMENT_CD" AS varchar(5))) + '*' +
           rtrim(cast(t1."ORDER_NO" AS varchar(25))) +
          CASE WHEN S1."EXISTS" IS NOT NULL
               THEN  RTRIM(CAST(t1."TEST_REPORTING_MATERIAL_SID" AS varchar(10)))
               ELSE  '*-'
          END as sum_key, t1.SALES_ANALYSIS_CD
    FROM   dbo.TBLTEST_ALL T1
    LEFT   JOIN (SELECT 1 AS "EXISTS"
                 FROM   dbo.TBLTEST
                 WHERE  TEST_REPORTING_MATERIAL_SID > 0
                 GROUP  BY DOCUMENT_NO, COMPANY_CD, INVOICE_SEQ_NO,
                           DOCUMENT_ITEM_NO, ORDER_NO

  • Need Help on Sql Query

    Hi,
    I have a client requirement to show a report on the device availability. The report should show the output as

    Formula for Availability = (Total No. of Failed/Total No. rows) * 100
    My Oracle Table has the following data
    NODE     SUMMARY
    172.16.10.55     Default Interface Ping fail for 172.16.10.55: ICMP timeout
    172.16.10.55     Default Interface Ping restore for 172.16.10.55

    In the above table the Summary column has the details like 'Ping fail' , 'Ping restore' for each Node. So, for each Node I have to compute the Total Ping Fail / (Total Ping Fail + Ping Restore) * 100 to compute the availability %.
    My output should be like the below
    Node Availability%
    172.16.10.55 55.55
    172.16.10.56 54
    Can someone please help me with query.
    I appreciate your help in advance.
    Thanks.

    My Oracle Table has the following dataThat's great, but if you want maximum response to your question, then post CREATE TABLE + INSERT INTO statements.
    I currently do not have the time to turn your data into them.
    And always post the database version you're using.
    http://tkyte.blogspot.com/2005/06/how-to-ask-questions.html
    Also use the {noformat}{noformat} tag in order to post examples that benefit from staying formatted and thus readable when posted on the forum.
    Simply put the tag before and after your examples.
    For example, when you type:
    {noformat}select *
    from dual;{noformat}
    it will appear as:select *
    from dual;                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • Need help on Update query

    Hi,
    I have 2 tables A and B with below data and description, i want to update Table B when C1, C2 are equal and C3 is not equal by comparing with Table A. If A contains 2 records with same such condition then update any 1 record's different description in Table B.
    I can achieve this by using below query but i don't want to query Table A twice. Also if this is update is possible using Cursor is also fine for me..
    Please help me on this...Thanks in Advance
    Query
    Update B
    set B.c3 = (select c3 from A
    where A.c1 = B.c1
    and A.c2 = B.c2
    and A.c3 <> B.c3
    and ROWNUM = 1)
    where exists (select 1 from A

    I am a bit confused. this also works without numbers in the C3 column.
    drop table tablea;
    drop table tableb;
    create table tablea as
    (select 1 C1,'B' C2, 'descA' C3 from dual union

    merge into tableb t1
    using (
