Table1:
CustomerId
CustFname
CustLname
Convertion_Date
Table2:
CustomerId
DFname
DLname
CustomerId is used for joins .
Now i need a query based on conversion_date.
If conversion_date <sysdate
then
select CustomerId ,CustFname,CustLname,Convertion_Date from Table1
else
select CustomerId,DFname,DLname from Table2

    Query like
    SELECT * FROM MASTER WHERE V_VALUE IN (<input value>) ;
    if given input value 6 means, how to split the value into 4 and 2....
    if given input value 12 means, how to split the value into 4,8....
    like wise.... for all the combinations..... for the above table values.
    if i give the input value 6 means, i need the query like
    select * from master where v_value in (2,4).
    is split the value is possible by user define function?
    like
    select * from master v_value in (userdefine_function(<input value>));
    if possible means give the function code.

  • Need a SQL Query (URGENT)

    Hi Folks,
    I have 2 tables, in which the 1st one has 200 columns and 2 table had 2 columns.. There is one common column for both the tables, but there is little change in schema of the tables...The common col in 2nd table is a primary key but the same column in the 1st table is a ordinary one..The data type for the common column is same...
    Now i need to write a query to select 199columns(except the common column)from the 1st table and the other column(2nd col)other than the common column frm the 2nd table for "table1.commoncolumn=table2.commoncolumn"......
    I had tried the natural join but its nt working in my informix sql database....I also tried by explicitly mentioning column names like "select column1,column2....column199,table2.column2 from table1,table2 where table1.commoncolumn=table2.commoncolumn", but its having a severe performance impact.......
    Can some please suggest a query for the above one?? Thankx in advance..

    Please gimme possible solutions & suggestions regarding the above query....
    The informix z forum very slow...The problem is, you labeled your questions badly. As this is a forum of volunteers people tend to react badly to the use of the word "urgent" in the subject line. Nobody's question matters more than anybody else's. In fact some regulars won't answer questions with "urgent" in the strapline as a matter of principle.
    Then when we get to actually read your question it turns out to be a question about Informix. I guess not many people here use Informix so your potential pool of responders is pretty small (for instance I'm not even sure how to spell it).
    It's not our fault the Informix forums are so lame.
    Anyway, what I suggest is you repost your question with a new title: (Off topic) Need help with an INFORMIX query.
    At least that will attract people who might be able to answer your question. Then you need to include the actual query you're running and all the supporting details necessary for people to understand the nature of the performance impact.
    You need to ask the right people and you need to ask the right question. This is standard etiquette (and indeed common sense) regardless of which forum you're using.
    Cheers, APC

  • Need help in query tuning

    Hi All,
    In my application I have 3 tables. Event(1.2 L records), KeyWord(1K records) and Event_KeyWord_Mapping(1.4 L records) table.
    In my query i need to sort the Events table by 3 columns -( 1 Date column and 2 String column) and i am interested only in top 40 records.
    Below is the example query.
    select
        from
            (    select
                      a.*,

                        this_.EVENT_GMT_DATE ,
                        this_.PRIORITY    
                    from
                        EVENTS this_,

    A few questions:
    1. Are any indexes available on the Event_KeyWord_Mapping table?
    2. What does '1.4 L records' mean? Not familiar with 'L'.
    3. Are the statistics up to date for the tables and indexes involved?
    4. Are EVENT_ID and KEYWORD_ID the only columns accessed from the Event_KeyWord_Mapping table?
    Assuming the above then DarkStargate's suggestion is on point.
    But you should add the KEYWORD_ID column to the index as well since that is what the index records are filtered on.
    AND  ekp.keyword_id IN (
                            1643,2278,24,1090,2422,401 )Be sure that index statistics are collected; they will provide Oracle with data about the distribution of KEYWORD_ID values.
    This will allow Oracle to get the required information from the index without accessing the Event_KeyWord_Mapping table itself.

  • Need help in query to have all items in sap with PO data on order, date

    Hello Everyone,
    I need some help in writing a query to show all items in sap db to have itemcode, itemname, onhand, sellable(onhand-committed), on order, and the delivery date when that time should be received.  I need to know what items are regular items, which ones are master and components.  For the master I need to have the deliver date of the PO for the component.
    I have written this.
    SELECT DISTINCT TOP (100) PERCENT T1.ItemCode, SUM(T1.Sellable) AS Sellable, T1.OnOrder, MAX(T1.Docduedate) AS DeliveryDate, T1.WhsCode
    FROM         (SELECT     ItemCode, Sellable, OnOrder, '1/1/1900' AS Docduedate, WhsCode
                           FROM          dbo.V_RAZ_StoreInv
                           UNION ALL
                           SELECT     TOP (100) PERCENT ItemCode, '0' AS Sellable, Quantity AS Onorder, DocDueDate, WhsCode
                           FROM         dbo.V_RAZ_OPENPOSDATA
                           ORDER BY ItemCode) AS T1 LEFT OUTER JOIN
                          dbo.V_RAZ_ItemInfo ON T1.ItemCode = dbo.V_RAZ_ItemInfo.ItemCode
    GROUP BY T1.ItemCode, T1.OnOrder, T1.WhsCode, dbo.V_RAZ_ItemInfo.OnHold
    HAVING      (dbo.V_RAZ_ItemInfo.OnHold = 'n')
    ORDER BY T1.ItemCode, T1.WhsCode
    and for the v_raz_openposdata I have the following query
    SELECT     dbo.OPOR.DocNum, dbo.OPOR.DocStatus, dbo.POR1.WhsCode, dbo.POR1.ItemCode, dbo.POR1.Dscription, dbo.POR1.Quantity, dbo.POR1.OpenQty,
                          dbo.POR1.LineStatus, dbo.OPOR.DocDueDate
    FROM         dbo.OPOR LEFT OUTER JOIN
                          dbo.POR1 ON dbo.OPOR.DocEntry = dbo.POR1.DocEntry
    WHERE     (dbo.OPOR.DocStatus = 'O')
    Any help is greatly appreciated. 
    Right now I do get the delivery date for regular items and components but the master sku for the component all of them have 1/1/1900. 
    Thank you

    Thank you for replying Gordon.  I did not remember I had asked this before.  I no longer have access to the other account. 
    What I need on the query is that I want  a list of items with the on order quantity and when we are expecting this order to be received.  The receiving date is based on the PO delivery date.  The trick here is that  I need to Master sku to show the delivery date of the component sku.  In my scenario all components have the same delivery date for the Master sku.  If there are mulitple delivery dates because each warehouse is getting them on a different date then I want to get the delivery date for that warehouse.
    Let me know if this is possible and if yes please guide towards a query for it.
    Thank you.

  • Need help with query joining several tables into a single return line

    what i have:
    tableA:
    puid, task
    id0, task0
    id1, task1
    id2, task2
    tableB:
    puid, seq, state
    id0, 0, foo
    id0, 1, bar
    id0, 2, me
    id1, 0, foo
    id2, 0, foo
    id2, 1, bar
    tableC:
    puid, seq, date
    id0, 0, 12/21
    id0, 1, 12/22
    id0, 2, 12/22
    id1, 0, 12/23
    id2, 0, 12/22
    id2, 1, 12/23
    what i'd like to return:
    id0, task0, 12/21, 12/22, 12/22
    id1, task1, 12/23, N/A, N/A
    id2, task2, 12/22, 12/23, N/A
    N/A doesn't mean return the string "N/A"... it just means there was no value, so we don't need anything in this column (null?)
    i can get output like below through several joins, however i was hoping to condense each "id" into a single line...
    id0, task0, 12/21
    id0, task0, 12/22
    id0, task0, 12/23
    id1, task1, 12/23
    is this possible fairly easily?

    Whenever you have a question, it's even better if you post CREATE TABLE and INSERT statements for your sample data, like this:
    CREATE TABLE     tablea
    (       puid     VARCHAR2 (5)
    ,     task     VARCHAR2 (5)
    INSERT INTO tablea (puid, task) VALUES ('id0',  'task0');
    INSERT INTO tablea (puid, task) VALUES ('id1',  'task1');
    INSERT INTO tablea (puid, task) VALUES ('id2',  'task2');
    CREATE TABLE     tablec
    (       puid     VARCHAR2 (5)
    ,     seq     NUMBER (3)
    ,     dt     DATE          -- DATE is not a good column name
    INSERT INTO tablec (puid, seq, dt) VALUES ('id0',  0,  DATE '2010-12-21');
    INSERT INTO tablec (puid, seq, dt) VALUES ('id0',  1,  DATE '2010-12-22');
    INSERT INTO tablec (puid, seq, dt) VALUES ('id0',  2,  DATE '2010-12-22');
    INSERT INTO tablec (puid, seq, dt) VALUES ('id1',  0,  DATE '2010-12-23');
    INSERT INTO tablec (puid, seq, dt) VALUES ('id2',  0,  DATE '2010-12-22');
    INSERT INTO tablec (puid, seq, dt) VALUES ('id2',  1,  DATE '2010-12-23');This way, people can re-create the problem and test their ideas.
    It doesn't look like tableb plays any role in this problem, so I didn't post it.
    Explain how you get the results from that data. For example, why do you want this row in the results:
    PUID  TASK  DT1        DT2        DT3
    id0   task0 12/21/2010 12/22/2010 12/22/2010rather than, say
    PUID  TASK  DT1        DT2        DT3
    id0   task0 12/22/2010 12/21/2010 12/22/2010? Does 12/21 have to go in the first column because it is the earliest date, or is it because 12/21 is related to the lowest seq value? Or do you even care about the order, just as long as all 3 dates are shown?
    Always say what version of Oracle you're uisng. The query below will work in Oracle 9 (and up), but starting in Oracle 11, the SELECT ... PIVOT feature could help you.
    i can get output like below through several joins, however i was hoping to condense each "id" into a single line... Condensing the output, so that there's only one line for each puid, sounds like a job for "GROUP BY puid":
    WITH     got_r_num     AS
         SELECT     puid
         ,     dt
         ,     ROW_NUMBER () OVER ( PARTITION BY  puid
                                   ORDER BY          seq          -- and/or dt
                           )         AS r_num
         FROM    tablec
    --     WHERE     ...     -- If you need any filtering, put it here
    SELECT       a.puid
    ,       a.task
    ,       MIN (CASE WHEN r.r_num = 1 THEN r.dt END)     AS dt1
    ,       MIN (CASE WHEN r.r_num = 2 THEN r.dt END)     AS dt2
    ,       MIN (CASE WHEN r.r_num = 3 THEN r.dt END)     AS dt3
    ,       MIN (CASE WHEN r.r_num = 4 THEN r.dt END)     AS dt4
    FROM       tablea    a
    JOIN       got_r_num r  ON   a.puid  = r.puid
    GROUP BY  a.puid
    ,            a.task
    ORDER BY  a.puid
    ;I'm guessing that you want the dates arranged by seq; that is, for each puid, the date related to the lowest seq comes first, regardless of whther that date is the earliest date for that puid or not. If that's not what you need, then change the analytic ORDER BY clause.
    This does not assume that the seq values are always consecutive integers (0, 1, 2, ...) for each puid. You can skip, or even duplicate values. However, if the values are always consecutive integers, starting from 0, then you could simplify this. You won't need a sub-query at all; just use seq instead of r_num in the main query.
    Here's the output I got from the query above:
    PUID  TASK  DT1        DT2        DT3        DT4
    id0   task0 12/21/2010 12/22/2010 12/22/2010
    id1   task1 12/23/2010
    id2   task2 12/22/2010 12/23/2010As posted, the query will display the first 4 dts for each puid.
    If there are fewer than 4 dts for a puid, the query will still work. It will leave some columns NULL at the end.
    If there are more than 4 dts for a puid, the query will still work. It will display the first 4, and ignore the others.
    There's nothing special about the number 4; you could make it 3, or 5, or 35, but whatever number you choose, you have to hard-code that many columns into the query, and always get that many columns of output.

    I haven't been here before. For some crazy reason when I try to save a re-sized image with a different dpi, PS6 indicates I have saved it. But if I go to re-open the same image, its in a different (but proportional) size and its original dpi.  I also
