transfer data to another table

I'm using Oracle 10.2.04. I have a table table1 that has about half a million records. At the end of the year 90% of these files are only needed for purposes of archiving during 1 year.

We are planing to create archive table table2 to say is similar to table1 so that we can insert data redundant from table1 to table2 and delete the records from table1. In this way table1 is be much smaller and faster to work with.

I want to know experts in the forums, what they think of our approach and insert and delete. Is there a better way to do it. I was consider adding a flag column, maybe partitioning etc. I would like to know what you think. All the tips and suggestions is greatly appreciated.

I'll get exactly the records that would be redundant. I only meant those recordset is 90% of the total number of records.

If you say so.

  • Redirect data to another table using before insert trigger.

    Dear all,
    How can I redirect the data to another table in a before Insert trigger? My database is Oracle10g.
    I have a table EMP (EMP_ID, LAST_NAME, SALARY).
    I have another EMP_COPY table with the same structure. I also have a before Insert trigger on the EMP table.
    Based on a condition that I have to redirect the data in table EMP_COPY. Let's say the condition is EMP_ID = 100.
    I fire an insert on EMP table for example INSERT IN EMP(EMP_ID,LAST_NAME,SALARY) VALUES(100,'Dev',500).
    On the inside of the front Insert trigger on the EMP table, I have the code
    IF EMP_ID = 100 THEN
    INSERT INTO EMP_COPY (EMP_ID, LAST_NAME, SALARY)
    VALUES(:NEW.) EMP_ID,: NEW. LAST_NAME,: NEW. SALARY);
    COMMIT;
    ON THE OTHER
    NULL;
    END IF;
    But the problem here is that data goes to EMP table of origin also although I don't want. He should do an Insert into EMP table only if EMP_ID! = 100.

    One way has been to raise a user-defined exception inside the If statement and not handle it so that the original insert on table EMP fails but INSERT comes in the EMP_COPY table. But in this solution since the inside the trigger unhandled exception, it propagates to the calling environment. And I can't stand outside relaxation as the calling environment is a form of Oracle Apps standard that cannot be customized.

    Any kind of help will be highly appreciated that I am fighting for more than two weeks.

  • Select table data in another table

    Hello

    I want to select data from A table, which is not in table B.

    Currently I am doing:

    Select
    smofnut,
    nameA,
    dobA
    a.
    If smofnut not in
    (select A snoB, B).
    where smofnut = snoB
    and nameA = Name)

    But above all it is very slow.

    I can do something like:

    Select
    smofnut,
    nameA,
    dobA
    of A, B
    where
    EXCLUDE (smofnut = snoB and nameA = Name)

    Please note that I need the place where the condition on the two columns.

    any help will be appreciated.

    -Harvey

    What are approximate data to A and B?
    What is 'very slow '?
    What version of Oracle?
    What is the query plan?

    Without knowing anything about your system, my first thought would be to see if a NOT EXISTS happened to be faster for your data

    SELECT snoA,
           nameA,
           dobA
      FROM a
     WHERE NOT EXISTS (
        SELECT 1
          FROM b
         WHERE a.snoA = b.snoB
           AND a.nameA = b.nameB )
    

    Of course, I don't know why you want to join A & B in your NOT IN subquery. It would seem that you would need just a subquery correlated, i.e.

    SELECT snoA,
           nameA,
           dobA
      FROM a
     WHERE snoA NOT IN (
        SELECT snoB
          FROM b
         WHERE a.snoA = b.snoB
           AND a.nameA = b.nameB )
    

    This should be more efficient than the original request. The NOT EXISTS version may or may not be more effective than NOT IN according to data volumes.

  • update of data from another table

    Hi, I would like to help. I Don t know how I can start doing:


    I have a table with a column with numbers (primary key) and I need to create another column with the same values,


    I want to change a table that has only numeric values (PK) to another
    value, so I disable the constraints of linked tables
    then I create another column that I called the "d" column and copy the values
    from column A to column D

    For example.

    TABLE XYZ

    COLUMN A: COLUMN D: (NEW)

    00001 00001
    00002-00002
    00003-00003
    00004 00004


    Can I change the values in column A and D of the column will be kept

    TABLE XYZ
    COLUMN A: COLUMN D:

    00001 99901
    99902 00002
    99903 00003
    99904-00004


    As the tables that must "point" to the column, I change the values with the new numbering

    TABLE ZZZZ

    COLUMN B: (the values of the column before the change)

    00001
    00002
    00003
    00004
    ...

    I want it like this:

    99901
    99902
    99903
    99903
    99904
    ...


    In other words, I find the current value in column D of the XYZ table for the new value that is in column a.

  • read in select data from another table

    Hello world.

    IM Oracle11GR2 database.

    I m facing the following problem:

    I have 2 tables.

    In the first picture, I have a few articles and 3 of these items then come.

    (A) point Varchar2

    (B) Item Varchar2.

    (C) point digital and this point is the id of a record in the other table.

    If the digital point > 0 then points A and B must be read in the second table

    In the second table, I have 3 Articles.

    (A) the id of the record.

    B & C point are also point varchar2 and must be read in the first table, point C is > 0.

    I'm looking for the way that when I write a normal selection in the first picture he gives me the point B & C of the second table if C point in the first table is > 0.

    I thought to solve this problem with a trigger or something similar.

    Any idea is welcome.

    Regards to everyone.

    You don't need a trigger for this. A simple select statement should do. Something like that? I got your if condition perfectly.

    SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

    BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

    T1. C

    FROM T1;

    Look at the following example. Check if it fills your scenario.

    -BEGINNING OF THE SAMPLE DATA

    WITH T1 AS)

    SELECT 'A' A, 'B' B, 1 C OF DOUBLE UNION ALL

    SELECT 'C', ', 2 DOUBLE UNION ALL

    SELECT 'DF', 'G', THE DOUBLE 0),

    () AS T2

    SELECT 1, 'X' B 'Y' C DOUBLE UNION ALL

    SELECT 2, 'Z', 'BB' OF THE DOUBLE)

    -END OF THE SAMPLE DATA

    SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

    BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

    T1. C

    FROM T1;

    OUTPUT:

    A  B           C

    -- -- ----------

    X Y 1 - since c > 0 A and B values in table 2 are replaced

    Z BB 2 - since c > 0 A and B values in table 2 are replaced

    DF G 0 - since c = 0, there is even value in table 1

  • Copy a column of data in another table?

    Hello world

    I am a beginner SQL who spent ridiculous amounts of time trying to find a solution to a problem no doubt very simple.

    I have two tables composed of 162000 lines each. A table has the following format:

    table T1

    PID NUMBER
    NUMBER OF PG
    NUMBER OF PCS
    PS NUMBER
    NUMBER OF PL
    NUMBER OF DRIFTWOOD

    (coercion, but a simple data)

    The DRIFTWOOD column is empty, all the others are completely filled.

    The other table is filled only one column:

    table T2

    NUMBER OF CALCULATEDCHANCE

    My intention is to copy all the rows in the column T2 CALCULATEDCHANCE in the column CYBERJER from T1.

    Insert will not work because it adds records. I tried to use the update, but maybe I don't get the syntax right. All I got is to copy the first value of DRIFTWOOD in all lines of CALCULATEDCHANCE.

    Thanks in advance for your answers!

    We have a database of CARS 2 knots with 4 terabyte of shared storage. Current size of the DB is only 1 TB stored in Diskgroup DATA1.
    Can I create a new disk group and move all of the data in DATA1 (1 to) to the newly created disk group?

    If this is not possible in 10 gr 2, is it possible in GR 11, 2?

    Hi Pete,.

    Can I create a new disk group and move all of the data in DATA1 (1 to) to the newly created disk group?

    I think the best way to do this is:

    When you add new disks in the same diskgroup, and then remove the old drives.
    ASM perform the automatic migration of data to new disks without having to create a new diskgroup, whitout donwtime. (on 10g you can do)

    If you need to rename the diskgroup in Oracle 11 g R2 you can do.

    If this is not possible in 10 gr 2, is it possible in GR 11, 2?

    Yes... its possible. (if you can migrate partial data)
