SQL - alternate rows from 2 tables

Hi, not sure how to best put this, but I have 2 tables for a Sales database. One is for our Sales Agents Actual sales (Agent_Sales, Product, Jul, Aug, Sep, Oct....) showing the actual sales by agent. PK is composite Agent_Sales and Product. The other table is similar but for the Targets (Agent_Target , Product, Jul, Aug, Sep, Oct....) with the PK again being composite Agent_Target and Product.
What I would like to do is get a listing for each agent in a table listing the actuals on the first line, then Targets on the second. Furthermore the 3rd line will be the variance between actuals and target and 4th line a percentage to target.
I would like the output to look like this:
Jul Aug Sep Oct
Agent_Sales 8 9 10 8
Agent_Target 9 8 8 9
Variance -1 1 2 -1
Percent 0.89 1.12 1.25 0.89
Thanks in advance.

Hi,
Another way:
WITH  cntr  AS
     SELECT  LEVEL  AS n
     FROM     dual
     CONNECT BY  LEVEL <=4
SELECT     a.agent_sales
,     a.product
,     DECODE (c.n, 1, a.jul, 2, t.jul, 3, t.jul-a.jul, 4, a.jul/t.jul)     AS jul
,     DECODE (c.n, 1, a.aug, 2, t.aug, 3, t.aug-a.aug, 4, a.aug/t.aug)     AS aug
,     DECODE (c.n, 1, a.sep, 2, t.sep, 3, t.sep-a.sep, 4, a.sep/t.sep)     AS sep
,     DECODE (c.n, 1, a.oct, 2, t.oct, 3, t.oct-a.oct, 4, a.oct/t.oct)     AS oct
FROM          actual_sales     a
JOIN          target_sales     t     ON     a.agent_sales     = t.agent_sales
                         AND     a.product     = t.product
CROSS JOIN     cntr          c
ORDER BY  a.agent_sales
,         a.product
,         c.n
;It sounds like each row in each table has a matching row in the other table. If that's not the case, then you might want to make the join between actural_sales and target_sales an outer join. All the computations might be messier, if they need NVL or NULLIF to deal with missing items.
I wonder if this is the best table design. Perhaps something with a separate row for each month would be better.

  • Deleting rows from a table

    COuld anyone tell me how to delete rows from a table which has millions of rows.
    TIA,
    Oracle user

    if you are deleting all the rows, use "truncate table" in sql*plus.
    or if you are deleting all but a handful of rows, then copy the rows you still want to a spare table, drop the original table, and rename the spare table back to the original table's name.
    hope this helps

    Choosing How Foreign Keys Enforce Referential Integrity
    Oracle Database allows different types of referential integrity actions to be enforced, as specified with the definition of a FOREIGN KEY constraint:
    Prevent Delete or Update of Parent Key The default setting prevents the deletion or update of a parent key if there is a row in the child table that references the key. For example:
    CREATE TABLE Emp_tab ( 
    FOREIGN KEY (Deptno) REFERENCES Dept_tab);Delete Child Rows When Parent Key Deleted The ON DELETE CASCADE action allows parent key data that is referenced from the child table to be deleted, but not updated. When data in the parent key is deleted, all rows in the child table that depend on the deleted parent key values are also deleted. To specify this referential action, include the ON DELETE CASCADE option in the definition of the FOREIGN KEY constraint. For example:
    CREATE TABLE Emp_tab (
        FOREIGN KEY (Deptno) REFERENCES Dept_tab 
            ON DELETE CASCADE); Set Foreign Keys to Null When Parent Key Deleted The ON DELETE SET NULL action allows data that references the parent key to be deleted, but not updated. When referenced data in the parent key is deleted, all rows in the child table that depend on those parent key values have their foreign keys set to null. To specify this referential action, include the ON DELETE SET NULL option in the definition of the FOREIGN KEY constraint. For example:
    CREATE TABLE Emp_tab (
        FOREIGN KEY (Deptno) REFERENCES Dept_tab 
            ON DELETE SET NULL);

  • Deleting a row from a table containing CLOB as one of the columns

    When i delete a row from a table which contains a CLOB (internal clob) i.e. CLOB or BLOB column, Will the CLOB data will also be deleted ? I understand that what exactly stored in the CLOB column is the clob locator which points to the actual data.
    So, when I delete this row, the clob locator will be deleted, but will the actual data what this locator is pointing to is also deleted ??? if not what is the process to delete the data the locator is pointing to when the row containing the locator is deleted ? If this is not happening then the actual data might become an orphan data which nobody has access to, will automatic garbage cleaning occurs on a frequent intravels to delete unaddressed data residing on the database server ?
    Thanks in advance for the help, can email me at [email protected] alternatively.
    Regards,
    Srinivasa C.

    Michael,
    Thanks very much for your inputs, here are the results i got when i tried the way you explained in your answer, the TRUNCATE command made the actual size back to normal, but the delete is not the same, so, how can i delete the data that a particular clob locator may point to ?
    truncate would delete all the rows of the table, which might not serve my purpose, i would like to delete a row and also it's associated clob data from the database! is there anyway to do this ?
    is there any limitation on the ool_sample size? i am basically a c++ programmer, i am looking for some function like FREE which would free the allocated memory to the clob once the locator is deleted.
    your help is greatly appreciated - Thanks!
    :-) Srini.

  • How NOT to restrict no of rows from two tables

    I have two identical tables Invoice and Payment. The only difference is Invoice_id,Invoice_Amt and Payment_id,Payment_Amt columns that shows different ids and amounts. The bank_ids, names, account_types are same. Invoice table has 3 rows and Payment has 2. Simply meaning that there were 3 invoices generated but the bank received 2 payments. I want to show Invoice_Amt and Payment_Amt using sql query. But its giving me total 6 rows. Whereas, I want 3 from Invoice and 2 rows from Payment table to show side-by-side.
    CREATE TABLE invoice
    ( invoice_id NUMBER
    bank_id NUMBER,
    bank_name VARCHAR2(256),
    invoice_amount NUMBER);
    ----Invoice table has 3 rows showing 3 Invoice Amts
    CREATE TABLE payment
    ( payment_id NUMBER
    bank_id NUMBER,
    bank_name VARCHAR2(256),
    payment_amount NUMBER);
    ----Payment table has 2 rows showing 2 Payments
    After executing this sql statement below, I get 6 rows:
    select inv.invoice_amount,pymt.payment_amount from invoice inv,payment pymt where inv.bank_id=pymt.bank_id;
    How can I show 3 rows for Invoice and 2 for Payment..?
    Thank you.

    Hi,
    So you want
    the 1st invoice to appear side-by-side with the 1st payment,
    the 2nd invoice to appear side-by-side with the 2nd payment,
    the nth invoice to appear side-by-side with the nth payment.
    But, if there are an uneqaul numner of payments and invoices, all the payments and all the invoices must still be shown, alone on a row if necessary.
    That sounds like a job for FULL OUTER JOIN.
    Use the analytic ROW_NUMBER fucntion to determine which is the 1st, 2nd, ..., nth row in each table, for each bank.
    WITH     invoice_plus_r_num     AS
         SELECT     bank_id, bank_name
         ,      invoice_amount
         ,     ROW_NUMBER () OVER ( PARTITION BY  bank_id, bank_name
                                   ORDER BY          invoice_id
                           )         AS r_num
         FROM    invoice
    ,     payment_plus_r_num     AS
         SELECT     bank_id, bank_name
         ,      payment_amount
         ,     ROW_NUMBER () OVER ( PARTITION BY  bank_id, bank_name
                                   ORDER BY          payment_id
                           )         AS r_num
         FROM    payment
    SELECT       NVL (i.bank_id,   p.bank_id)          AS bank_id
    ,       NVL (i.bank_name, p.bank_name)     AS bank_name
    ,       i.invoice_amount
    ,       p.payment_amount
    FROM          invoice_plus_r_num     i
    FULL OUTER JOIN     payment_plus_r_num     p  ON   i.bank_id     = p.bank_id
                                        AND     i.bank_name     = p.bank_name
                                AND     i.r_num          = p.r_num
    ORDER BY  bank_id     -- you can use column aliases here
    ,       bank_name
    ,       NVL (i.r_num, p.r_num)
    ;You mentioned something about accounts, but didn't include that in the CREATE TABLE statements. You'll probably want to add that wherever I used bank_id and bank_name, above.
    Are invoce and payment actually views, rather than tables? If not, you should have a separate bank table, and only include the bank_id in the other tables.
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, 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.

  • Select unique rows from two tables...

    Hi,
    I have two tables, replies1 and replies2.
    SQL> desc replies
    Name Null? Type
    URN VARCHAR2(36)
    ADDRESS VARCHAR2(18)
    FILESIZE NUMBER
    AS_NUM VARCHAR2(6)
    SQL> desc replies2
    Name Null? Type
    URN VARCHAR2(36)
    ADDRESS VARCHAR2(18)
    AS_NUM VARCHAR2(6)
    Both of the tables have no primary keys, but I have indixes on (urn, addrss) combination on both....
    I am trying to select the unique rows with (urn, address) from replies2, and then find the matching size from replies...
    I am using the following query:
    select distinct replies2.urn, replies2.address, replies.filesize from replies2, replies where replies2.AS_NUM like 'XYZ' and replies.urn = replies2.urn;
    I cannot figure out why it won't work. the way I understand it is that, distinct will give all distinct combination of all column names that follow, which is what I want...
    I know it is wrong, because the query:
    select count(*) from replies2 where AS_NUM like 'XYZ' returns less number of rows than the above query.
    Any help would be greatly appreciated.
    Thank you
    Oz.

    Thanks a lot Mohan for your reply.
    urn is not a unique key. Several rows could have the same (urn, address) pair in both tables. What I want is retrieve all (urn, address) rows from one table, and find the size from the other table to make a (urn, address, size). I want all unique combinations of (urn, address) to appear in the output.
    AS_NUM is an empty column in replies... It would've been a lot easier if it wasn't, since then I'll just say: select distinct urn, address, filesize from replies where AS_NUM like 'XYZ';
    I will try your query though and let u know how it goes. It takes quite a while to run since my tables are huge.

  • Deleting Multiple Rows From Multiple Tables As an APEX Process

    Hi There,
    I'm interesting in hearing best practice approaches for deleting multiple rows from multiple tables from a single button click in an APEX application. I'm using 3.0.1.008
    On my APEX page I have a Select list displaying all the Payments made and a user can view individual payments by selecting a Payment from the Select List (individual items are displayed below using Text Field (Disabled, saves state) items with a source of Database Column).
    A Payment is to be deleted by selecting a custom image (Delete Payments Button) displayed in a Vertical Images List on the same page. The Target is set as the same page and I gave the Request a name of DELETEPAY.
    What I tried to implement was creating a Conditional Process On Submit - After Computations and Validations that has a source of a PL/SQL anonymous block as follows:
    BEGIN
    UPDATE tblDebitNotes d
    SET d.Paid = 0
    WHERE 1=1
    AND d.DebitNoteID = :P7_DEBITNOTEID;
    INSERT INTO tblDeletedPayments
    ( PaymentID,
    DebitNoteID,
    Amount,
    Date_A,
    SupplierRef,
    Description
    VALUES
    ( :P7_PAYMENTID,
    :P7_DEBITNOTEID,
    :P7_PAID,
    SYSDATE,
    :P7_SUPPLIERREF,
    :P7_DESCRIPTION
    DELETE FROM tblPayments
    WHERE 1=1
    AND PaymentID = :P7_PAYMENTID;
    END;
    The Condition Type used was Request = Expression 1 where Expression 1 had a value of DELETEPAY
    However this process is not doing anything!! Any insights greatly appreciated.
    Many thanks,
    Gary.

    ...the "button" is using a page level Target,...
    I'm not sure what that means. If the target is specified in the definition of a list item, then clicking on the image will simply redirect to that URL. You must cause the page to be submitted instead, perhaps by making the URL a reference to the javaScript doSubmit function that is part of the standard library shipped with Application Express. Take a look at a Standard Tab on a sample application and see how it submits the page using doSubmit() and emulate that.

    I need to insert rows from another table if there is gaps in my transaction table. For each ärendenr there should be 5 Id status rows (1-5). Except for the fact that the inserted rows never should have higher IdStatus number then the highest value from
    the transaction for each Ärendenr. See my example below that illustrates my transaction table, Stages master and the desired result.
    Is there some t sql code that could handle this problem?
    Best regards
    Arne
    So far i have tried to solve this with the code below but it doesnt work.
    I have copied the transaction file information to the TempLogTransTimes
    and then insert into LogTransTimes
    IF OBJECT_ID('dbo.TempLogTransTimes', 'U') IS NOT NULL --Här raderas den tillfälliga tabellen
    DROP TABLE dbo.TempLogTransTimes;
    SELECT *
    INTO TempLogTransTimes
    FROM LogTransTimes
    DECLARE @TopÄrende INT
    WHILE EXISTS(SELECT * FROM TempLogTransTimes)
    BEGIN
    SET @TopÄrende = (SELECT TOP(1) Ärendenr FROM TempLogTransTimes ORDER BY Ärendenr)
    INSERT INTO LogTransTimes(Ärendenr, IdStatus, StatusNamn, SourceId)
    SELECT @TopÄrende, SM.IdStatus, SM.StatusNamn, 'Beräkning'
    FROM Statusmall SM
    FULL JOIN TempLogTransTimes LT ON SM.IdStatus = LT.IdStatus
    WHERE LT.IdStatus IS NULL
    DELETE TempLogTransTimes WHERE Ärendenr = @TopÄrende
    END

    Hi Arne Olsson, try this..
    DECLARE @Transactions TABLE
    Id1 INT,
    IdStatus INT,
    StatusName VARCHAR(10)
    DECLARE @Stages TABLE
    IdStatus INT,
    StatusName VARCHAR(10)
    INSERT INTO @Transactions VALUES(1,1,'AA'), (1,3,'CC'), (1,5,'EE'), (2,1,'AA'), (2,3,'CC')
    INSERT INTO @Stages VALUES (1,'AA'), (2,'BB'), (3,'CC'), (4,'DD'), (5,'EE')
    ;WITH CTE AS(SELECT DISTINCT Id1 FROM @Transactions)
    SELECT Id1, IdStatus, StatusName FROM CTE, @Stages
    EXCEPT
    SELECT Id1, IdStatus, StatusName FROM @Transactions
    Please mark as answer, if this has helped you solve the issue.
    Good Luck :) .. visit www.sqlsaga.com for more t-sql code snippets and BI related how to articles.

  • Retrieving Odd numbered rows from a table.

    In one recent interview I have been asked to write a SQL query to retreive Odd numbered rows from any table. At first I am confused on how to say whther a perticular row is odd or even. If it is based on rownum then rownum is not dynamic and every time the rownum changes for a perticular row. I finally used rowid for this puprpose, as you all of you know rowid is alphanumeric its not worked.
    Can you please posta query to retrive odd numbered rows if its possible.

    Can you please posta query to retrive odd numbered rows if its possible.As you say, if there's nothing in the data itself to offer a distinction as to what is "odd" and "even" then the closest thing is the rownum.

    7 rows selected.Anything else is making an assumption as to what is "odd" and "even". If it were me, the answer would be to do the above and also explain that, without any definition of what constitutes "odd" and "even" this is the closest possible, but not an accurate science as there is no guarantee as to the order of the records.

  • Display distinct rows from Oracle table without using "DISTINCT" keyword.

    How to retrieve distinct rows from oracle table without using 'DISTINCT' keyword in SQL?
    Thanks in advance.

    Welcome to the forum.
    Besides GROUP BY you can use UNIQUE instead of DISTINCT as well, but that's probably not wanted here ;) , and the ROW_NUMBER() analytic:
    SQL> create table t as
      2  select 1 col1 from dual union all
      3  select 1 from dual union all
      4  select 2 from dual union all
      5  select 3 from dual union all
      6  select 4 from dual union all
      7  select 4 from dual;
    Table created
    SQL> select col1 from t;
          COL1
             1
             1
             2
             3
             4
             4
    6 rows selected
    SQL> select distinct col1 from t;
          COL1
             1
             2
             3
             4
    SQL> select unique col1 from t;
          COL1
             1
             2
             3
             4
    SQL> select col1 from t group by col1;
          COL1
             1
             2
             3
             4
    SQL> select col1
      2  from ( select col1
      3         ,      row_number() over (partition by col1 order by col1) rn
      4         from   t
      5       )
      6  where rn=1;
          COL1
