I have to write a procedure that accepts schema name, table name and column value as parameters....I knew that i need to use metadata to do that deleting manually.
View 9 RepliesI want to delete records from parent table which are less than 2 years. Before deleting records from parent table we have to delete records from child table. How can we delete those records. I don't want to use ON DELETE CASCADE.
MASS_MASTER --parent table.
MASS_CHILD --child table.
The below query is used to delete records from parent table.
DELETE FROM mass_master WHERE last_date<=ADD_MONTHS(sysdate,-24);
The child table MASS_CHILD is not having last_date column. provide me the query to delete same records from child table.
We 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?
View 1 Replies View Related, 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 ;"
I 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?
I have a parent table and child table. I want a row to be deleted from the parent table which is referenced by a child row. Is there a way to achieve this. I dont have permission to re create the table or alter the table using delete cascade option. Is there a way to do it in sql.

I have a DB that has one parent table with many child tables. I would like to delete all records(child - parent) based upon a particular "net_id". I have three versions that "seem" to work BUT I'd like to use "version2" because I want to go to the parent one time(for the parent delete I just made it simple for me) only and be able to delete the child record(s) from the child table(s). I want to achieve this w/o using triggers...
My question: Is version2 an "ok" way to delete child records or should I try another method(version1 or 3)??
create table PARENT
(
event_id NUMBER,
event_title VARCHAR2(50),
net_id VARCHAR2(16)
);
--truncate table parent;
insert into parent
(event_id, event_title, net_id)
values
(1, 'title1', 'CURLY');

I am selecting around 10000 records in a recordset using an sql query.I need to delete these 10000 records from 10 different tables as each of the table have these records.I can use a FOR Loop for each record one by one to delete these 10K records from each tabel but i was wondering if i can delete there 10K in one go so that the program would Loop Only once rather thatn 10K times.
Mine Delete code looks like:
if x.first is not null then
for i in x.first..x.last loop
delete tbl_A where trade_id = x(i).trade_id;
delete tbl_B where trade_id = x(i).trade_id;
[code]...
Where x is the recordset having around 10K records.Is there any way i can run the loop only once rather than one by one for 10K times.
Sqty is sold qty , rqty is return qty , sdate is sold date , vno is billno .
When we enter sdate , this will fetch the products sold on the given date , and total sold qty .
If some products are returned which are entered in rqty , then this should delete all the records of the product on that sdate , and these products as spread along several billno's .

3) If there are more than 3 duplicate records ex: ID is 3 and Group is AA, the i have to delete all the records with qty value either 30 or 0 and.
I have written a query like below.
SELECT id,

while i'm inserting a records into the table tablespace has got full and next statement which is commit is executed
so now i need to remove the data due to the last insert into the table.

I have a service that executes a pl/sql function (legacy app) to delete records from multiple tables. This function works fine in development, and has worked fine in production until about a week ago. I'm not a DB guy but the DB guys are trying to say this is an application issue. That may be, be the "insuff privileges" really leads me to believe otherwise.
What is causing this type of Oracle error? Permissions between dev and prod are the same, yet it works in dev but not prod.

DELETE FROM sre_t WHERE TO_CHAR(end_dt,'yyyy')<'2000'

TABLE NAME :ABC
(PARTITION BASE TABLE - 84 Partition and each Partition has 500-800 Millions of Records)
/* Step1 Create MATERIALIZED VIEW LOG */
CREATE MATERIALIZED VIEW LOG ON ABC;
/* Step2 Create MATERIALIZED VIEW Refresh after Every 20 Minutes */
CREATE MATERIALIZED VIEW MV_ABC
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE+20/ (24*60) AS
SELECT * FROM ABC
WHERE TMSTP > SYSDATE-1;
Scenario:Intially data extracted will be "Greater than SYSDATE-1 = 18/08/2009 11:27:39 " - 76 Millions of Records After 20 Min of FAST Refresh, it will add 2500 Records
i)Is query in the MVIEWS (MV_ABC) SYSDATE-1 will be changed on each FAST Refresh, as observation (as per definition) it is incrementing the records to intial extracted data?
ii)As COMPLETE Refresh will be expensive to execute on the partition base table on each refresh.
Is there any alternative way to achieve the Nature of COMPLETE REFRESH in Materialized View?
iii)Is Delete or Conditional Delete option is possible in Materialized View (i.e not a delete from the base table but the delete from MVIEWS)?
iv)What is the machnism for populating the logs for MVIEWS?Is it overhead for the system and better than a Trigger based approach?
Im a oracle pl/sql developer but I didnt learn oracle as a language. With my sql skills I started working on Oracle.In my project every table has an associated MLOG$ table for it.
For eg.
CREATE TABLE MLOG$_TEST
(
ID VARCHAR2(64 BYTE),
SNAPTIME$$ DATE,
DMLTYPE$$ VARCHAR2(1 BYTE),
OLD_NEW$$ VARCHAR2(1 BYTE),
CHANGE_VECTOR$$ RAW(255)
)
So is MLOG$_TEST oracle's internal table.
Whenever an insert/update/delete happens it is recorded in MLOG$ tables as I/U/D for the priamry key.So if I do a bulk delete of records in tables an entry is made into MLOG$ tables. So deleting old records in a database doesn't free much space.If this is oracle internal table is it advisable to delete from MLOG$ tables too.
My oracle database is mounted on the Linux server.If I delete bulk records in tables from which path I can see how much space is freed.
write a query to delete similar records in particular fields(columns) in different tables.

I have 1000+ tables in a DISCOVER tablespace in 10g.
I need to drop ALL tables in this area and leave the tblsp intact so that I can IMP a data update from 9i (prod) into 10g (test).
Is there an easy cmd to drop all the tbls, or am I missing someway to do this in DB Console for 10g.
Is there a SQL query to find out the redundant or unused table in Oracle.
Some tables shows no dependencies to itself or other schemas,but has got valid data in it, deleting it will affect the functionality of the system.
