I want to delete data from say 100 tables without disable the constraints.
Tables having foreign key.. which is giving error if I select table randomly to delete.
I want to know the query which will give me the sequence of all tables based upon dependencies, so that If i delete the data on that sequence, it wont give me child record exists error.
I knew, how to enable or disable a constraint on a table.
>alter table <table_name> disable constraint <constraint_name>;
But if we know all the data is correct, it's better to disable all constraints to improve the performance.
We are allowed to Disable or Enable only a single constraint.
Enable or Disable All Constraints.
how to disable and enable all constraints pertaining to one table at once. I want to disable them at once and also enable them at once. I make use of TOAD.

View 4 Replies View RelatedI have a table with 2 defined FK constraints which fires delete cascade events.
I want to deny deletions when the event is fired from one of the tables and permit them when the event is fired from the other table.
Is it possible?

I want to create a store procedure to copy data from a source tables(which may not have any constraints defined) to a table which has primary key, foreign key and unique key constraints.
Any records which are rejected due to these constraints not being satisfied need to go another table.
Once the initial data load is done, these procedures need to be automated(through cron) to do the future incremental uploads in the same manner.

View 1 Replies View RelatedWith 11gr2, by default, on STARTUP, the standby database is open
-> in READ ONLY mode
-> with Intended State: APPLY-ON
so the ACTIVE DATAGUARD option is in use ....
is there a way to deactivate REAL TIME QUERY permanently, so whether on STARTUP or STARTUP MOUNT, the standby stay only mounted with Intended State: APPLY-ON
The only way i found is to do the following :
SQL> startup

then

I am trying to disable mouse navigation on data block or text item,. What i want is to my text items in specified block be keyboard navigable only.
The problem is that i don't have that option on text_items or data block (my conclusion: probably because it is not possible to change mouse navigate option for text item or data block).
I have also tried in WHEN-NEW-BLOCK-INSTANCE trigger
set_item_property('block.item', mouse_navigate, property_false)
and
set_block_property('block', mouse_navigate, property_false)
and of course it did not work.
how to insert data in a table by deleting previous entered data and only inserting current data like:

I have a table with around 650,000,000 rows and we need to delete about 60,000,000 rows at the end every month and same amount of rows accumulate throughout the month. The deletion usually takes overnight to delete. We are using 10r2 in IBM AIX. The procedure we are using to delete is:

ln_count number:=0;
begin
for i in (select rowid from table1 where some_id<2012090000)

delete from table1

When this procedure is started I mostly see that the session is busy in user i/o wait for db sequencial file read. Will using cursor instead will give better results.

I haved drop a datafile on Primary,and the archived log has transported to Standby,but the datafile is still exist in Standby.
Primary
alter tablespace tps_hxl
drop datafile '/u02/app/oracl/oradata/hxl10.dbf';
We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.

based on the above result set , for a particular group ,only that op will be retained which comes out in the query . say for example , we have got 1,2,3,'D' for group 1,2,3
now since we have got the D Operation from the above query , i don't need the other two rows .i.e.
(1,2,3,'I');
(1,2,3,'U');
what is the best way to delete the data we don't want retaining the rows we want ,using a single sql statement . Also , for the result set row 7,7,7,T I first need to delete the group containing T operation, and insert two new rows .i.e. 7,7,7,D and 7,7,7,I .

We have two Windows 2008 VMs with Oracle 11G configured as primary and standby.This configuration has been defined by a partner who is no longer working for us.We have broken the correct application of the redo log on the standby when we have not correctly restored some snapshots on those two VMs.I would like to create a new Oracle server that will become the new standby. For that, I need too :
- Display the full dataguard configuration to reproduce it on the new server
- Stop (delete ?) the configuration on the primary server.
We also have the current problem that RMAN refuses to delete old archivelog since they have not been applied to the standby.
