I want to know how we can insert more than 3 million records from one table to another table. Can we use Bulk collect and forall to insert the all data.Can we use create table tableB as select * from tableA; From the above which is one is performance wise good.
View 16 RepliesOracle 11gI have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company. I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information. select records from this 125 million record table to insert into the smaller table.
I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches. My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause? My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market asWITH got_pairs AS ( SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no , ROW_NUMBER () OVER ( PARTITION BY l.address_key ORDER BY l.hh_verification_date DESC ) AS r_num FROM t3_universe e JOIN t3_universe l ON l.address_key = e.address_key AND l.zip_code = e.zip_code AND l.p1_gender != e.p1_gender

View 1 Replies View RelatedLets take the basic emp table for our Referenece and lets assume that it contains around 60000 Records and all the deptno in that table are Initially 10. Please provide an update statement which would update deptno column of EMP table((based on) order by EMPNO) in for every 120 records incrementing by 1.(DeptNo to be incremented by 1,like 10 ,11 , 12 etc).
First 120 Records deptno should be 10,
Next 120 Records deptno should be 11, and so on.

I would like to know if we can insert 300 million records into an oracle table using a database link. The target table is inproduction and the source table is in development on different servers.The target table will be empty and have its indexes disabled before the insert. if this can be accomplished in less than 1 hour.

I want to update a table 8 million records of a table which has 10 millions records, what could be the best strategy if the table has a BLOB column with 600GB worth of data. BLOB itself is 550GB. I am not updating the BLOB column. Usually with non-BLOB data i have tried doing "CREATE TABLE new_table as select <do the update "here"> from old_table;" method .
View 6 Replies View Relatedthe problem is: 2 tables - one with 2 million records, and the other with 8000 records.
i need to compare for each record in a table if there's a similar string on the other table.
i've created a procedure that does the following:
opens the first cursor (select col1,col2,col3,col4... from table 1)
loop
opens second cursor (select col1 from table 2)
loop
if utl_match(col1, table2.col1) > 80 then
insert col1,col2,col3,col4... into tableX
end if
close second cursor
close first cursor
the thing is that this procedure takes forever to end...about 8 days.
is it because im using the utl_match function? is there a way to speed this up?
Ways for improving the Table performance which holds million of records for oracle. Currently we have partitioning and indexing but it doesn't seem to work.

View 2 Replies View Related following is the requirement
External Table
WKSHT_FILE_EXT
wksht_line
Export Table
Wksht_export
global_idvarchar2(10)
wksht_linevarchar2(250)
[code]....
Step 1.Insert all records from the external table into the export table. Truncate the export table first
Step 2.Read in a record from the export map table
Step 3.Search through export table records looking for the key words BRANCH =. Compare the branch code with the branch code form the map table
Step 4.If a match is found mark all records in the export table for the worksheet with the global ID from the export map table as follows..The first line of a worksheet is marked by the words WKSHTS..The last line of the work sheet is marked by the words COMPANY CONFIDENTIAL..We will need to capture the line break so also mark the next line after the COMPANY CONFIDENTIAL line
Step 5.Continue with Steps 2 - 4 until all records have been processed from the export map table.
first I have to create a procedure ti insert data from external table to export table.Global id will be blank.it will be updated by the mapping table's Global Id when The EB COLUMN's data(i.e 8p,2Betc ) will match with the BRANC=NA,2Betc of the datasheet loaded from the external table.. FOLLOWING IS THE SAMPLE DATASHEET
WKSHTS AAAAA BBBBBBBBBBB ELECTRONICS INC. TIME REPORT-DATE PAGE
SORT - BR, SLSREP AEC FIELD SALES REPRESENTATIVE 16:14 09/21/12 1
BRANCH = 2B
EMPLOYEE NAME SALVAAG, GREGG Days in the Month 28
[code]....
THERE ARE 2 pages..I have to split this LONG REPORT STORED IN WKSHT_LINE COLUMN OF EXPORT TABLE to 2 records..like wise 500 pages are there means 500 records.. AND THEN FIND BRANCH= after that which two words will come i.e NA,2B etc if it will MATCH WITH MAPPING TABLE"S EB COLUMN"S DATA,THEN MAPPING TABLE's GLOBAL ID WILL BE UPDATED TO EXPORT TABLE's GLOBAL ID WHICH IS BLANK

Trying to auto insert the newest records from one table into another Table. I have a vendor provided table that is part of my database (running Oracle 9i) so I can't change the underlying structure to it or their process stops fluxing. However, I can add a trigger to it. What I want to do is this:
When the vendor's software inserts a new row (through their own automated process) I want to insert data from that same new record into another table of my own. (where of course I can re-format it, etc., and make the data my own)
The original vendor table does not have a insertion timestamp field to work off of.What is the best way to trigger an insert off the latest inserted record? It works to replace all the records in the entire vendor table but I only want to insert one record at a time.
We are trying insert records from a select query into temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select * from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.

I'm trying to convert a two character value using CASE statement:

I keep getting an ORA-01861 literal does not match format string error.
I have created below function to remove specific words/special characters from string. This function is producing expected result. Using this function i need to insert around 900000 records in name_compress table. Insert is taking around 7 mins, how we can tune this function so that insert will be executed within 1-2 mins.
Function -
CREATE OR REPLACE FUNCTION NAME_FN(IN_STRING1 VARCHAR2)
RETURN VARCHAR2 IS

V_OUTPUT1 VARCHAR2(300);

I am working on form builder 6i. I have multi record datablock 't1'.' I have 'Submit' Button, which contains 'commit_form'. I am able to insert records.

If check_box ='Y' THEN
INSERT_RECORD
end if.
SUBMIT BUTTON: commit_form.
