Copying large amount of data from one table to another

We have a requirement to copy data from a staging area (consists of several tables) to the actual tables. The copy operation needs to
1) delete the old values from the actual tables
2) copy data from staging area to actual tables
3) commit only after all rows in the staging area are copied successfully. Otherwise, it should rollback.
Is it possible to complete all these steps in one transaction without causing problems with the rollback segments, etc.? What are the things that I need to consider in order to make sure that we will not run into production problems?
Also, what other best practices/alternative methods are available to accomplish what is described above.
Thanks,
Eser

It's certainly possible to do this in a single transaction. In fact, that would be the best practice.
Of course, the larger your transactions are, the more rollback you need. You need to allocate sufficient rollback (undo in 9i) to handle the transaction size you're expecting.

Copying large amount of data from one table to another getting slower

I have a process that copies data from one table (big_tbl) into a very big archive table (vb_archive_tbl - 30 mil recs - partitioned table). If there are less than 1 million records in the big_tbl the copy to the vb_archive_table is fast (-10 min), but more importantly - it's consistant. However, if the number of records is greater than 1 million records in the big_tbl copying the data into the vb_archive_tbl is very slow (+30 min - 4 hours), and very inconsistant. Every few days the time it takes to copy the same amount of data grows signicantly.
Here's an example of the code I'm using, which uses BULK COLLECT and FORALL INSERST to copy the data.
I occasionally change 'LIMIT 5000' to see performance differences.
DECLARE
TYPE t_rec_type IS RECORD (fact_id NUMBER(12,0),
store_id VARCHAR2(10),
product_id VARCHAR2(20));
TYPE CFF_TYPE IS TABLE OF t_rec_type
INDEX BY BINARY_INTEGER;
T_CFF CFF_TYPE;
CURSOR c_cff IS SELECT *
FROM big_tbl;
BEGIN
OPEN c_cff;
LOOP
FETCH c_cff BULK COLLECT INTO T_CFF LIMIT 5000;
FORALL i IN T_CFF.first..T_CFF.last
INSERT INTO vb_archive_tbl
VALUES T_CFF(i);
COMMIT;
EXIT WHEN c_cff%NOTFOUND;
END LOOP;
CLOSE c_cff;
END;
Thanks you very much for any advice

Assuming that there is nothing else in the code that forces you to use PL/SQL for processing, I'll second Tubby's comment that this would be better done in SQL. Depending on the logic and partitioning approach for the archive table, you may be better off doing a direct-path load into a staging table and then doing a partition exchange to load the staging table into the partitioned table. Ideally, you could just move big_tbl into the vb_archive_tbl with a single partition exchange operation.
That said, if there is a need for PL/SQL, have you traced the session to see what is causing the slowness? Is the query plan different? If the number of rows in the table is really a trigger, I would tend to suspect that the number of rows is causing the optimizer to choose a different plan (with your sample code, the plan is obvious, but perhaps you omitted some where clauses to simplify things down) which may be rather poor.

Transporting large amounts of data from one database schema to another

Hi,
We need to move large amount of data from one 10.2.0.4 database schema to another 11.2.0.3 database.
Am currently using datapump but quite slow still - having to do in chunks.
Also the datapump files quite large so having to compress and move across the network.
Is there a better/quicker way?
Habe haerd about transportable tablespaces but never used them and don't know about speed - if quicker thana datapump.
tablespace names different in both databases.
Also source database on solaris opertaing system on sun box
target database on aix on ibm power series box.
Any ideas would be great.
Thanks

Pl quantify "large".

It may be possible, assuming you do not violate any of these conditions

T code to Copy Data from one table to another table

Hi,
I want copy all data of one table to its copy table. Anyone knows transaction code to copy data from one table to another table.
Regards,
Jigar Thakkar.

Hi
Create a small program.
Extract data from T1 - database table and put it in one internal table - itab1.
loop the itab1 data .............
insert itab1 into tab2. (tab2 - second database table)
endloop.
try this....
hope it works....

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?

Barry

Move data from one table to another table

Hi all,
I had a custom table called sales_data in that table there are columns like JAn,FEB,upto DEC including other columns so in each month there is some data total data is 23000 count but each month has has specific data like JAn-2500,FEB-2000 like that it has total 23000 records
My Requirement is i have to move data from one table to another table that too if i will pass jan only jan data should move like that feb,march,.....
in my table there is no month column i had get it from another table called gl_periods and by using cursor and case function i have written the code
well while when i am inserting data am passing year,month as parameters but 23000 data is moving it should get like that.
Please suggest me.its urgent
Thank You

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,
Tom

You should use nologging and parallelism options

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.

Insert old missing data from one table to another(databaase trigger)

Hello,
i want to do two things
1)I want to insert old missing data from one table to another through a database trigger but it can't be executed that way i don't know what should i do in case of replacing old data in table_1 into table_2
2)what should i use :NEW. OR :OLD. instead.
3) what should i do if i have records exising between the two dates
i want to surpress the existing records.

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
Jafar

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
Jafar

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.

Copying data from one table to another table thru java

Hi
I have to copy data from table emp in Database A to table emp in Database B. My input would be table name and number of rows to be fetched. these rows i need to insert in table B.
The problem over here is I won't be having any info. of table emp i.e the number of columns it has and their type.
So is their any way i can copy the data from one table to other without having the info abt the number of cols and their type.
TIA

Couldn't copy large amount of data from enterprise DB to Oracle 10g

Hi,
I am using i-batis to copy data from enterprise DB to oracle and viceversa.
The datatype of a field on EDB is 'text' and the datatype on oracle is 'SYS.XMLTYPE'
i am binding these to a java string property in a POJO to bind values.
I could successfully copy limited amount of data from EDB to oracle but if there is more data, i am getting the following exceptions with different oracle drivers ( but i could read large amount of data from EDB):
--- Cause: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column

I have latest oracle 10g jdbc drivers.
remember, i could copy any amount of data from oracle to EDB but not otherway around.
PLease let me know if you have come across this issue, any recommendation is very much appreciated.
Thanks,
CK.

Hi,
I finally remembered how I solved this issue previously.
The jdbc driver isn't able to directly call the insert with a column xml_type. The solution I was using was to build a wrapper function in plSQL.
Here it is (for insert but I suppose tha update will be the same)
create or replace procedure insertXML(file_no_in in number, program_no_in in varchar2, ost_XML_in in clob, btl_XML_in in clob) is
begin
insert into AQAOST_FILES (file_no,program_no,ost_xml,btl_xml) values(file_no_in, program_no_in, xmltype(ost_XML_in), xmltype(btl_XML_in));
end insertXML;
here is the sqlmap file I used
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap
PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-2.dtd">

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');
