PL/SQL :: How To Truncate Data In Table Partitions
Aug 9, 2013I 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;
I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit

View 7 Replies View RelatedTruncate Partition From PL/SQL Package
May 8, 2013I 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.

SQL & PL/SQL :: Truncate Partition - Resource Busy?
Sep 1, 2010i 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?

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.
