i have one question that why oracle not set high water mark when we delete data from a table and commit it, on the other hand it set in case of truncate.both of these statement release physical structure(in case of delete after commiting)
View 7 Replieswhen we try to truncate the parent table data although its child tables are empty, the oracle oracle throws an error--"ORA-02292: integrity constraint test_id_constr violated - child record found" , but when we delete this parent table data by "delete" statement then it gets deleted. what is the logic behind "truncate".
View 3 Replies View RelatedAny impact is there if is do the following:
ALTER TABLE MY_TABLE TRUNCATE PARTITION P1 UPDATE GLOBAL INDEXES;
will there be any lock on the table during this operation? DML operations will work without any issue or not?
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 Replies View RelatedI have an Oracle Package with a procedure in which
package with a procedure in which there is a truncate partition, ALTER TABLE table_name TRUNCATE partition_name DROP STORAGE and the all is run with an EXECUTE IMMEDIATE 'alter table ...' .
The point is that the procedure in the package is started from another DB via DB Link (schema USER1) and doesn't work because of lack of privileges.
Instead, if the same procedure is started as a procedure, standalone, not in the package but from the same user (USER1) it works perfectly.
Don't understand why and which privileges must give to the user to run the procedure from inside the package.
Is it possible to recover a table which is Truncated

The Scenario is that we have Master and detail table (With Foreign key enabled), we want to TRUNCATE Master table.
1) Is there any option which can Truncate the table without disabling the constraints for child tables...we want to Truncate the table forcefully..

I have two tablespace a and a_idx , a is comtaining all tables data and it fixed size is 19000MB and b containing all the index associated with these tables and its size also 19000MB.
but this is am testing database, and we need some space on my unix machine for this i truncate all tables from a tablespace a
and resize the tablespace a with size 1000M with no error.
but as per my understanding after truncating all tables from tablespace a its also release space from tablespace b but its not hapening.
so my questin is how can i reize tablespace B using alter database datafile 'full path of dbf file' resize 1000M.
I have found one interview question no.7 @ [URL] According to that it can be rollbackQuote:The truncate command is a DDL operation and just moves the high water mark and produces few rollback data.
But, I read That is not true in the case of oracle but it is true in the case of SQL Server.
i have many user tables in my database and i want to truncate selected tables and how i can overcome this scenario.
i can truncate using truncate table <table_name> but they are 250 tables to truncate, so,i can't write truncate command for every table. if i want to truncate first i have to truncate parent table or child table and how i can find parent table and child table for given tables to truncatein my database.

How a truncate command comes under DDL section, instead DML. All the operations happening inside the object is called DML and ON the object is called DDL.

i have one procedure that run at same time for two different partition.In the begin of the processes i do the truncate partition and after that the insert of data in the partition.Since i have two processes running at the same time, i will fill up data in two different partition.
But it occurred one error :
"ORA-00054: resource busy and acquire with NOWAIT specified"
The problem is caused by the truncate partition. I'm doing two simultaneous execution of the same process, but when one process is doing the truncate other is insert data.How can i do the truncate of this two partition, or insert in to, without get any error. I think the two simultaneous insert is not a problem.
So how can i lock the table in the first truncate and after that release the table for the next truncate?
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.

I couldn't either DROP or TRUNCATE the table partitions that were created. Here are the DDLs and DMLs I'm using.
Create table student(no number(2),name varchar(2)) partition by range(no) (partition
p1 values less than(10), partition p2 values less than(20), partition p3 values less
than(30),partition p4 values less than(40));
Insert into student values(1,'a');
Insert into student values(11,'b');
Insert into student values(21,'c');
Insert into student values(31,'d');
When I do the following query, it returns data.
SELECT * FROM STUDENT PARTITION(p1);
But, when I try to perform any of the following queries, it says invalid partition name.
ALTER TABLE STUDENT DROP PARTITION p4;
ALTER TABLE STUDENT TRUNCATE PARTITION p3;
