On Delete Cascade
Mar 27, 2007We have a bunch of tables with FKs but we do not have the 'on delete cascade' option on these FKs. If I want to delete records in the database do I have to write delete statements for each table starting with the lowest child or is there a cascade option I can use with the delete statement?

Oct 27, 2013, we have used alter table to change the constraint in on delete cascade. there is two option. what is different between both ofthem. Example:1)Alter table t3 add constraint t2_F foreign key (id) references t2(id,column2,column3) on delete cascade ;or2)Alter table t3 add constraint t2_F foreign key (id) references t2 on delete cascade ;
know first one that particular column will set to on delete cascade.What is the use of second one in this case we are not using column name in "foreign key (id) references t2 on delete cascade ;"
SQL & PL/SQL :: Constraints And Delete Cascade Events
May 9, 2011I 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?
Is any way to solve which table fires the event?
Gathering Statistics With Cascade Option Is Slow
Oct 9, 2012The database is 11.2.0.3 on a linux machine. I issued the following command, but the session was a little slow. The table size is about 50 GB and has 3 indexes. I specified "degree=8" for parallel processing.
When gathering statistics on the table , parallel slaves were invoked and gathering statistics on the table has finished fast enough. However, when it goes to gathering statistics on the indexes, only one active session was invoked, and thus "degree=8" option was ignored.
My question is :
Do I need to use dbms_stats.gahter_index_stats instead of "cascade" option in order to gather statistic on the indexes with parallelism?
exec dbms_stats.gather_table_stats(ownname=>'SDPSTGOUT',tabname=>'OUT_SDP_CONTACT_HIS',estimate_percent=>10, degree=>8 , method_opt=>'FOR ALL COLUMNS SIZE 1',Granularity=>'ALL',cascade=>TRUE)

View 9 Replies View RelatedForms :: Insert And Update Directly Into Table From Pre Update Trigger Of Block?
May 14, 2010 I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
Update Statement Versus Cursor Based Update
Sep 7, 2010I have to update 20 and 60 million records of a table. The update statement are
1> 20 million recs
update mycustomer set update_time=add_months(sysdate,240) where seq_num = 1;
commit;
2> 60 million recs
update mycustomer set update_time=sysdate-seq_num where seq_num <> 1;
commit;
Q1> Is there any way to improve performance
Q2> Will parallel dml improve performance
Q2> Would a pl/sql cursor make any difference in speed.
SQL & PL/SQL :: Update Statement With Join Only Update Matching Rows
Aug 17, 2010This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.
SQL & PL/SQL :: Create Trigger That Will Update Table When There Is Insert / Update
May 29, 2012i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
*Action: Rewrite the trigger (or function) so it does not read that table.

SQL & PL/SQL :: Compound Trigger Update Firing Update
Jan 25, 2012After many tests I can't make work and update of the same table inside the same table.
Trying to avoid Mutating Table Error now I have
ORA-00036: maximum number of recursive SQL levels (50) exceeded
Sample Data :
create table test_compound (USERID VARCHAR2(10),APP VARCHAR2(15),LAST_UPDATED_ON TIMESTAMP);
insert into test_compound values ('user1','1',systimestamp);
insert into test_compound values ('user2','2',systimestamp-4);
insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test
FOR UPDATE ON test_compound
COMPOUND TRIGGER
TYPE t_tab IS TABLE OF VARCHAR2(50);
l_tab t_tab := t_tab();
[code].......
When I execute :
update test_compound
set last_updated_on=systimestamp
where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.

SQL & PL/SQL :: Update Returns More Than One Row?
Oct 26, 2010I have to update a table by getting values from two other tables. While doing that the inner query returns more than one value. I am not sure how to implement the logic without returning more than one row in sub query.
My query:
update buf_office_str o
set o.manager_ident =
(select sp.ident
from se2_r_src_sourceperson sp ,
(select distinct director_name, team_name from buf_sales_dump )t
where SP.SRCNAME = upper(substr(t.director_name,instr(t.director_name,' ')+1,length(t.director_name))||', '||substr(t.director_name,1,instr(t.director_name,' ')-1 ) )
and o.office_descr = t.team_name
)
Basically the query gets the manager id from sp table where sp.srcname = t.team-name.
The office_descr should be equal to the team_name.
This is the logic I am working towards:
For each office, i get the office_descr and get corresponding team_name. Match the team's director_name (from table t) with the sp.name and return the employee's id (sp.ident) for that office_descr. I need to update all 50 offices with corresponding managerid for that office in buf_office_str table.
Is it possible to get done in one update? Or, does this need a plsql proc to do this logic.

Update Where Current Of
Sep 27, 2010I have a table I need to update called employee_history. It has almost the exact same values as another table called Employee. The difference being that the employee_history has a start date and end date. So it allows you to have overrides in the future. The employee table is static. So it only allows you to see the current data as of today.
I need to write an insert statement that will pull values from employee table and populate the employee_history table but I also have columns in the employee_history table that requires a next value and a start and end date.
From the employee table I want to select e.emp_id, e.emp_firstname, e.emp_lastname, e.shftpat_id, e.client_id from employee e
I want to INSERT INTO EMPLOYEE_HISTORY (EMHIST_ID, EMPHIST_START_DATE, EMPHIST_END_DATE, EMP_ID, EMP_FIRSTNAME, EMP_LASTNAME, SHFTPAT_ID, CLIENT_ID)
with the VALUES being (SEQ_EMPHIST_ID.nextval, TRUNC(sysdate), 01/01/3000 and the employee data from the employee table)). I bought the book Easy Oracle PL/SQL Programming but I am not finding what I need. It gives an example of a CURSOR FOR UPDATE and a reference to an UPDATE WHERE CURRENT OF.
The examples are straight forward where you take two columns from table one and update a new table with those values, or where you select a subset of employees that need a commission and update the emp table with that commission.
