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.

1.Is it necessary to reorganize a table and index after the deletion of records from table ? Because i see some change in table size after table and index reorganization.
2.Will re org table and index improve the database performance ?
shall we stop inserting data into a table before it inserting using Trigger?

View 3 Replies View RelatedI have a view SV (say) which holds approximately 33,000 records. But, when I try to insert these many records into a table SV_T (say) it is taking huge amount of time i.e. 2-3 hrs (approx.)
how reduce the time taken for the insert.
I'd like to insert a record between the records which are already in the table. There are over 40000 records, and I would like to place this new record at 19th place. How may I do so?
Let's consider an example with 5 records:
Table data:
CREATE TABLE enum
(identifier VARCHAR2(64),
code VARCHAR2(512),
data VARCHAR2(4000))
/
[Code]...
So when we check the table, we get:
SELECT * FROM enum
IDENTIFIER CODE DATA
---------- --------- ---------
HR_B_A Halli, L6 Halli, L6
HR_B_A Halli, L7 Halli, L7
HR_B_A Halli, L8 Halli, L8
HR_B_A Halli, L9 Halli, L9
HR_B_A Halli, P6 Halli, P6
HR_B_A Halli, P7 Halli, P7
What I would like to have when I run the select query:
SELECT * from enum
IDENTIFIER CODE DATA
---------- --------- ---------
HR_B_A Halli, L6 Halli, L6
HR_B_A Halli, L7 Halli, L7
HR_B_A Halli, L8 Halli, L8
HR_B_A Halli, L9 Halli, L9
HR_B_A Halli, L10 Halli, L10
HR_B_A Halli, P6 Halli, P6
HR_B_A Halli, P7 Halli, P7
The only way I can think of is transfer the data till L9 line in a table (e.g enum_temp), insert L10 line and then transfer the remaining data in that table. But I can't seem to figure out the syntax of the query.
I'm updating a large piece of legacy code that does the following type of insert:
INSERT INTO foo_temp
(id, varchar2_column)
SELECT id, varchar2_column
FROM foo;
We're changing varchar2_column to clob_column to accommodate text entries > 4000 characters. So I want to change the insert statement to something like:
INSERT INTO foo_temp
(id, clob_column)
SELECT id, clob_column
FROM foo;
This doesn't work, since clob_column stores the location of each text entry, rather than the actual content. But is there some way that I can achieve the insert with one call to a select statement, or do I need to select each individual record in foo, open the clob_column value, read it into a local variable and then write the content to the matching record in foo_temp?
I have Multi record Block and for that block i have created one button, if we press that buttion it will open new block and it will post the records, Unfourtunately that block table dont have Primary key or any constraints .. so when we press that buttoon multiple times .. its posting multiple times..
Now i need to restrict to that which is should not post the records multiple timies i have tried by controling the paraemter..I have created one Non data base item initially value i assigned to 'N"
if the value is "N" then am doing process and showing the records and after processing am assigning the value to 'Y', if there are multiple records , at block level in pre-record trigger am assigning as 'N'.
I'm calling sql loader recursively to load data from CSV files which has thousands of records in each file. If there are any duplicate records, the sql loader terminates with ORA00001. My query is how to ignore inserting duplicate records and continue with the load.
Most of the posts in forums suggests to use skip command. But i do not think that is a wise option in my case as we cannot predict the maximum error count. more over I have set up ERROR=0 in my code so that the code terminates in case thers is a data error.
any other way to ignore inserting duplicate records into the tables.
I got a form with few columns and a check_box. If the user selects n number of check boxes and click the button Save. The corresponding records should be inserted to XX_AP_CUSTOM table.
I have written the following below code in when-button-pressed trigger. With this i am able to insert only one record i.e where the current record indicator is there, even though multiple check-boxes(records) are selected.
declare
begin
IF :XXFBI_INV_QUOTE_ANAL_BLK.CHECK_BOX = 'Yes' THEN
--IF CHECKBOX_CHECKED(:XXFBI_INV_QUOTE_ANAL_BLK.CHECK_BOX) = TRUE Then
--app_insert.insert_record('WHEN-BUTTON-PRESSED');
insert into xxfbi.XXFBI_INV_QUOTE_ANAL(Item,

I know that i have to use last_record and first_record and for loop to insert multiple selected records, but dont know how to do it.
Let's consider such table that all rows fit into single block:
SQL> create table test as select rownum id, '$'||rownum name from dual connect by level <= 530;
Table created.
SQL> create index i_test on test(id);
Index created.
SQL>
SQL> begin
[code].....
why does approach with full scan take longer even if table occupies only one data block? PS. 11gR2
I have a huge table (about 60 gb) partition over range. The index on this table is global index created on 4 columns together. I have a query which is running very slowly. The explain plan is showing the use of this global index.Explain plan is not showing pstart and pend because the index is global.

I have created domain indexes on text columns of a materialised view to use "contains" clause when searching for data. The select query with "contains" clause does not return any records, however I was able to retrive data using via regular query using a like search.
-> will exec ctx_ddl.sync_index('index_name')'resolve my problem?
-> since the view is a materialized view, how can i make sure that the latest data added are also picked up?
Not sure if its an issue or just an Oracle "feature" of some sort. So I create a table with a specified partition/ sub partition template as follows:
CODEcreate table sr_part_test
(
part_key NUMBER,
subpart_key VARCHAR(10)
)
tablespace NORKOM_DATA
partition by range ( part_key )
subpartition by list ( subpart_key )
[code].......
Then when I split the MAX VALUE partition, all is hunky dorey and as expected:
CODEalter table sr_part_test split partition sr_part_max at (4) into
(
partition sr_part_4,
partition sr_part_max
);
select * from user_tab_subpartitions where table_name = 'SR_PART_TEST' and partition_name = 'SR_PART_4';
[code]......
But - what if I want to have new generated names and possibly even new subpartition keys? Won't work:
CODEalter table sr_part_test
set subpartition template
(
subpartition sp_1_NEWNAME values ('foo'),
subpartition sp_2_NEWNAME values ('bar'),
subpartition sp_3_NEWNAME values ('baz')
);
[code]........
Notice that the sub partition names are still using the old names (which I do NOT want), and still using the old keys! C .
I know that truncate is a ddl operation that removes all the data from the table and set the HWM to very beginning. I am curious to know, is anyhow indexes will be affected on the issuance of truncate command or we need to rebuild the indexes after issuing truncate.
Also is there any way to know that how many rows/blocks a select statement is scanning because of the effect of HWM even the table has 0 rows.
Is it Possible to get Marquee Effect in Form Text ?
