disable foreign keys

I want to truncate a table so I can import into it. But the table has a lot of foreign keys that refer to other tables. What is the best way to find and disable all keys referencing table?

This might work:

select 'alter table '||a.owner||'.'||a.table_name||
' disable constraint '||a.constraint_name||';'
from all_constraints a, all_constraints b
where a.constraint_type = 'R'
and a.r_constraint_name = b.constraint_name
and a.r_owner  = b.owner
and b.table_name = 'TEMP';

ORA-02266: permit to unique/primary keys in table referenced by foreign keys
Hello
I'm trying to delete data from a table by dropping a partition. I've identified all the child tables by running the following command.

Select "select count (*) from ' |" table_name |' where employee_id = 100; »
of dba_constraints
where constraint_type = 'R '.
and r_constraint_name in
(select constraint_name from dba_constraints
where constraint_type in ('P', 'U') and table_name =' EMPLOYEE);

"SELECTCOUNT (*) OF | TABLE_NAME | "WHEREEMPLOYEE_ID_ID = 100; »
-----------------------------------------------------------------------------------------------
Select count (*) in the PT_ORDERS where employee_id = 100;
Select count (*) in the PT_DEP where employee_id = 100;
Select count (*) in the PT_SKILLSET where employee_id = 100;

I dropped the score for number 100 in all child tables. The count (*) select returns 0 rows for each of the foregoing.

When I try to run the command on the EMPLOYEE table, below I get ' ORA-02266: unique/primary keys in table referenced by foreign keys enabled.

Drop partition ALTER table EMPLOYEE EMP_ID_100;

I don't see why I am unable to give up this partition now because it is data child present in any of the referenced tables. Any suggestions or help on this would be greatly appreciated.

Thank you.

You must first disable foreign key constraints and delete the partition. Deletion of lines or a fall in childs partitions do not work in this case
as you have the overall dependence:
```
SQL > create table scott.t (x int primary key, int y)

2 partition by (list (y)

3 values p_1 (1) partition, partition values p_2 (2))

4.
Table created.
SQL > create table scott.t_c (x int references scott.t (x), int y)

2 partition by (list (y)

3 values p_1 (1) partition, partition values p_2 (2))

4.
Table created.

I guess you should consider options such as partitioning Referencial (with some restrictions).

Drop partition without disabling the foreign key
Hi all

I have a table parent and child.

Parent table

create the table parent_1
(identification number,
create_date date,
Constraint parent_1_pk001 PRIMARY KEY (id))
PARTITION OF RANGE (create_date)
INTERVAL (NUMTODSINTERVAL(1,'DAY'))
(PARTITION parent_1_part VALUES LESS THAN (January 1, 2010 '));

Child table
create the table child_1
(identification number,
create_date date,
Constraint child_1_fk001 FOREIGN KEY (id)
REFERENCES parent_1 (id))
PARTITION OF RANGE (create_date)
INTERVAL (NUMTODSINTERVAL(1,'DAY'))

I have problems to delete partition.

You can do until you disable the foreign key constraint

stored procedure to disable all foreign key constraints?

Hi all

I need a stored procedure to disable / enable all the constraints in the database schema.

Create or replace procedure enable_disable_proc (status varchar2 schema_name varchar2 (20)) (3).
......
....
...

-> where the 'status' parameter condition must be (YES to activate) (NO to disable)
-> 'schema_name' is a setting where, this scheme should be affected by this procedure.

Thanks in advance...

Sorry Raineau, you have said foreign keys in the thread title, constraints cannot be turned on and off like that.

So for foreign keys:

CREATE OR REPLACE PROCEDURE enab_disab_proc (
   status          IN   VARCHAR2,
   current_schema   IN   VARCHAR2
)
IS

BEGIN
   FOR cur_rec IN (SELECT table_name, constraint_name
                     FROM user_constraints
                    WHERE owner = current_schema
                        AND constraint_type  = 'R')
     LOOP
      EXECUTE IMMEDIATE 'ALTER TABLE ' || cur_rec.table_name
                                       || CASE status WHEN 'YES' THEN ' ENABLE ' ELSE ' DISABLE ' END
                                       || 'CONSTRAINT '
                                       || cur_rec.constraint_name;

     END LOOP;

END;

This simple demo is simply representative of course. Our number of real paintings ~ 60, with hundreds of millions of records in a large number of tables, a tree FK covering several levels of depth, without the partition littered throughout key. Given that the volume of data, we try hard to avoid executing DELETE, which is why I explore PARTITION migration BY reference. The problem is not unlike the already-fixed Bug 9329773, but it is slightly different - especially that this variant is not resolved. If there is no way that such a facility would never fly, you have any suggestions that would not involve changes to application code? (For example, adding a partition to the tables key column kids won't fly, but I might be able to sell disabling constraints to developers.)

foreign key 'generate' strange behavior check box, any idea?

Summary: in the properties of the table, the foreign keys, the box generate behaves badly, and I don't understand why or how I got there.
Oracle Data Modeler 4.0.2.840 8.1 X 64 Windows, jdk1.7.0_55
the behavior is:
(1) add the foreign key (two different more to see strange behavior)
(2) uncheck 'generate' on a foreign key
(3) apply, Ok
(4) ask 'Preview DDL', a foreign key constraint is generated, SO FAR SO GOOD, I'm happy
5-now click on the button 'generate the DDL' for any design = > * * TWO foreign keys are generated?
(6) even more strange: sometimes the 'generate' check itself after step 5, most of the time is not
(7) at the beginning this has occurred for a couple of foreign key 'uncheckees', now it almost always happens.
The relational model was built by importing the SQL scripts already exist (try to migrate the Data Modeler). No too complex ~ 115 tables, 12 times.
I think it's a bug, but I can't find any reference on the web, maybe I do something wrong?

Hi Michel,.

The generation is different depending on whether or not the relevant storage design is open.

If the design of the storage is not open, the option "Generate DDL" on the foreign key is taken into account (for an overview of the DDL or full generation of DDL). For an entire generation of DDL, the foreign key will initially not selected phase in the generation of the DDL if Options the option "Generate DDL" on the foreign key has been disabled. (This change in the phase of the generation of DDL Options will also cause the option "Generate DDL" on the foreign key update.)

If the design of the storage is open, the option 'generate DDL"on the foreign key has no effect (in a Preview of DDL or full DDL generation).

Also in a generation full of DDL, an object will be initially marked as not selected if it has been disabled in the previous generation of DDL.

I hope that this helps to explain the behavior that you find.

Foreign keys without ON DELETE CASCADE; Database design question
It's the 3rd company, while I work, where I see that created foreign keys
```
ON DELETE CASCADE
```
clause.
My colleague said that it is created without the ON DELETE CASCADE clause in order to complicate the deletion of data (records of children). Thus, for codes of the Purge and archive, before we delete the parent table we must remove from the child table first.

Occasinaly, something is wrong and we will end up disabling FKs make them all and then purging, archiving, etc...

So, is it not better to create foreign keys with the clause ON DELETE CASCADE, rather than having all these hassles?

Experience, no matter what you think?
Personally, I am firmly in the removal of the brand of hard data camp. In the vast majority of cases, trying to remove an active parent is an error if the user must be informed of what they are trying to do and must make a conscious effort to do so (in other words, remove first the children).

XBR49X800D are there no option to disable the key tone?

XBR49X800D are there no option to disable the key tone? It is very annoying navigating around and hear tones every time I hit the buttons.

I have the XBR43X800D, but I think that the controls are the same. I turned off the annoying tone by changing its system to off. In the home menu, go to settings, sound then its system. This off my keytonw sound when navigating menus. I think that some applications may have their own sound tone so this may not work 100%.
