Transferring data from one table to another

I have two tables.i have some information existing in one of the tables.this information is defined at the broadest possible level e.g. Level A has one row.
I have to transfer this information to the other table when asked to by the user, but the problem is that the other table needs to have 64 rows created corresponding to the single row in the first table,i.e the other table will have 64 rows corresponding to a single row in the first table.
This needs to be done as quickly as possible so that the system does not hang and the other processing logic continues.
Moreover the first table can have more rows and each row may have 64 instances created in the other table when asked to by the user.
Please help if anyone has answer to this query.Any kind of algorithm will help.

Walk through the fist table, and for each row make 64 inserts.
Do it in one transaction (i.e. without autocommit) to speed it up a bit and improve data consistency. Don't forget to commit at the end. If that seems to be too slow, you can always make a stored procedure to do the same to avoid round trip time for each insert statement if the database is on another machine...

  • Transferring data from one table to another table using a Keycolumn using SSIS row by row dynamically

    Hi All,
    I have a Store Procedure(SP) which has a output variable name "AcivityID" which is the key column. In this SP, transformation  of data is done from one table to insert data into other table. I have to execute the SP and insert row by row data
    using the output variable "ActivityID"  whose value will keep on changing. How can I do it?
    Thanks,
    Kallu

    Value changing on a row by row basis? Not quite sure what you mean, but it seems that you want to use the results of an insert into one table as input for another. If so then SSIS is not needed, inside the stored proc use the SQL that will do that and for
    all records as
    INSERT A INTO dbo.table1
    OUTPUT INSERTED.A INTO MyTable;

  • Transfering Data from One table to another

    Hi all,
    Can we transfer data from Cluster Table to ZTABLE (Transparent Table)?
    if Yes, How can we do that?

    Hi,
    Generating a (surrogate) primary key value is usually done using:
    A) an Oracle sequence to generate a number
    B1) refer to the NEXVAL of the sequence in your insert statements
    or
    B2) a trigger on your agents table that populates agent_id by referring to the NEXTVAL of the sequence.
    Both approaches have pro's and con's, see what best fits your requirement.
    See this explanation (including examples):

  • Adding Data From One Table to Another

    Now, this doesn't strike me as a particularly complex problem, but I've either strayed outside the domain of Numbers or I'm just not looking at the problem from the right angle. In any case, I'm sure you guys can offer some insight.
    What I'm trying to do is, essentially, move data from one table to another. One table is a calendar, a simple two column 'date/task to be completed' affair, the other is a schedule of jogging workouts, i.e, times, distances. Basically, I'm trying to create a formula that copies data from the second table onto the first but only for odd days of the week, excepting Sundays (and assuming Monday as the start of the week). Now, this isn't the hard part, I can do that. The problem comes when I replicate the formula down the calendar. Even on the days when the 'if' statement identifies it as an 'even day', the cell reference to the appropriate workout on the second table is incremented, so when it comes to the next 'odd day', it has skipped a workout.
    I can't seem to see any way of getting it to specifically copy the NEXT line in the second table, and not the corresponding line.
    This began as a distraction to try and organise my running so I could see at a glance what I had to do that day and track my progress, but now it's turned into an obsession. SURELY there's a solution?
    Cheers.

    Hi Sealatron,
    Welcome to Apple Discussions and the Numbers '09 forum.
    Several possible ways to move the data occur to me, but the devil's in the details of how the data is currently arranged.
    Is it
    • a list of three workouts, one for each of Monday, Wednesday and Friday, then the same three repeated the following week?
    • an open-ended list that does not repeat?
    • something else?

  • Moving time-dependant data from one table to another (archiving)

    Hello all
    I would like to know if there's an easier solution or a "best practice" to move data from one table to another. The context of this issue can be found within "archiving".
    More concretely: we have an application that uses several tables to log information to.
    These tables are growing like crazy, and we would like to keep only "relevant" data in those tables, so I was thinking about moving data from these tables that have been in there for, say 2 months, to "archiving" tables.
    I figured there must be some kind of "best practice" to get this done.
    I have already written a procedure that loops the table that has the time indicator and inserts the records from the normal tables into the archive tables (and afterwards delete this data), but it seems to be taking ages to get it done.
    Thanks in advance!

    There is nothing to do with PL/SQL.

    Hello,

  • Moving Data from one table to another table

    Hi,
    I've a requirement to move large volumes (few billions) of data from one table to another empty target table. The target has more number of attributes and may not have same attribute name as the source. Please let me know what's the best method using oracle to move data in this case?
    Thanks in Advance,

    You should use nologging and parallelism options

  • Append data from one table to another.

    Hi,
    I want to insert/append some or all the data from one table to another table.
    For eg: Data from table table1 to be appended to table2 with the same constraints, indexes etc. The columns are same for both the tables.
    I am using 10g version 2.
    Please specify which method would be good for this process.
    Thanks

    INSERT INTO TABLE1 SELECT * FROM TABLE2;The above command would insert data into table2 and it also contain the old data.Is that right,
    Thanks

  • MySQL move date from one table to another

    I was wondering if there is a MySQL command that will let me move a selected row of data from one table to another. both tables have the same columns and declaration type (one table is actually an archived table on old data)
    example
    I wasnt to move all data in Table1 where the date is greater than 30 days old to Table 2
    -- so the result should be...import all rows to Table 2 where the date is greater than 30 days old..and delete all date from Table 1 that is greater than 30 days.
    currently..I'm doing three process
    1) get all row that is greater than 30 days  
        "SELECT * FROM Table1 WHERE TO_DAYS(NOW()) - TO_DAYS(dateField) > 30"
    2) insert data into Table2
        while (res.hasNext())
              TableData data = ..... // .get row
              dataList.add(data);
              for (int i = 0; i < dataList.size(); i++){
                    pstm.setString.....
                    pstm.addBatch()
              pstm.executeBatch();
    3) delete data from Table1
        "DELETE FROM Table 1 WHERE  TO_DAYS(NOW()) - TO_DAYS(dateField) > 30"

    for this app..losing a few rows does not
    impact on how we analyze the data.That's what everyone always tells me too. But 99% of the time they come back and want to know why the cannot balance and/or validate the data between two runs taken only minutes from each other.
    I've seen people puzzle over data for days that they swear they ran the exact same utility for their tests, but they were in fact using live data, and additional data had accrued but since all they had to do was execute the a script without parameters (they didn't put in a stop time), they got two different answers and it always, and I mean always confuses people. Be safe, and put the option in for and end date/time, then when they waste days trying to figure out why the two different observations gave them different numbers, they cannot blame you (because you gave them the option)!
    My 2 cents for the day...

  • How to copy data from one table to another (in other database)

    Hi. I would like to copy all rows from one table to another (and not use BC4J). Tables can be in various databases. I have already 2 connections and I am able to browse source table using
    ResultSet rset = stmt.executeQuery("select ...");
    But I would not like to create special insert statement for every row . There will be problems with date formats etc and it will be slow. Can I use retrieved ResultSet somehow ? Maybe with method insertRow, but how, if ResultSet is based on select statement and want to insert into target table? Please point me in the right direction. Thanks.

    No tools please, it must be common solution. We suceeded in converting our BC4J aplication to PostgreSQL, the MSSQL will be next. So we want to write simple aplication, which could transfer data from our tables between these 3 servers.

  • Loading data from one table to another using cursor

    Hi,
    I have given the below command to load the data from 1 table to another using cursor.
    declare
    cursor mycursor IS
    SELECT extract_name,from_date,to_date,BETA from temp_table where EXTRACT_NAME='GIFTCARD_DETAILS';
    Begin
    for mycursor_1 IN mycursor loop
    insert into tmp_tab columns(col1,col2,col3,col5) values(mycursor_1.EXTRACT_NAME,mycursor_1.from_date,mycursor_1.to_date,mycursor_1.BETA);
    End loop;
    commit;
    end;
    It is working fine.
    But I want to hard code some of the columns ( like flags ) which are not there in 1st table and load them into 2nd table.
    In db2 we will give commands like
    varSqlStatus=`db2 "declare mycurs cursor for select extract_name,from_date,to_date,BETA,'N','Y' from temp_table"`
    varSqlStatus=`db2 "load from mycurs of cursor modified by identityignore insert into tmp_tab(col1,col2,col3,col5,col6,col7) nonrecoverable"`
    But I want it in oracle 10g, Can any one help me in this.

    Have you tried either of the two options :
    1. Modify the CURSOR itself :
    cursor mycursor IS
    SELECT extract_name,from_date,to_date,BETA,'N','Y' from temp_table where EXTRACT_NAME='GIFTCARD_DETAILS';2. Modify the INSERT statement itself :
    insert into tmp_tab columns(col1,col2,col3,col5,col6,col7) values(mycursor_1.EXTRACT_NAME,mycursor_1.from_date,mycursor_1.to_date,mycursor_1.BETA,'N','Y');

    Hi lassiegirl,
    Welcome to Apple Discussions and the Numbers '09 forum.
    Apple provides two excellent resources that I recommend be downloaded by all Numbers users, the Numbers '09 User Guide and the iWork Formulas and Functions User Guide. You'll find linke for both of them in the Help menu in Numbers.
    The first will give you an overview of Numbers and how it works—spend some time with the preface and the first chapter, browse the rest on a need to know basis when you're doing something new. The second is a reference, useful when you're trying to write a formula.
    To your question...
    You can copy the sum from one table to another.
    For the example formula beow, both Table 1 and Table 2 have one header row and one footer row, and a total of 21 rows each.
    If the SUM on Table 1 is in cell C21, and you want to include it in the SUM of column C in Table 2, you could transfer the sum to C1 in the header row of Table 2 with:
    C1:  =Table 1::C21
    In C21 of Table 2 (a Footer row), use any of these formulas:
    =SUM(C)+C1
    =SUM(Table 1::C)+SUM(C)
    =SUM(Table 1 :: C,C)
    The first calculates the sum of the cells in column C (of its own table—Table 2) and adds the value in C1, the total transferred from Table 1.
    The second returns the same result by calculating the sums of the two columns separately, then adding those sums.
    The third takes the single arguments of the two SUM statements in the second, and lists them as multiple arguments in a single SUM statement.
    Regards,
    Barry
