SQL & PL/SQL :: How To Truncate Specific Sub Partition
Dec 3, 2010
I am using oracle11g. I want to truncate subpartition on specific partion.
I have partition on statewise. Each state partion has 7 day sub partition.
For intance,
Partion TX
Sub partition MON, TUE, WED, THU, FRI, SAT, SUN
Partion CA
Sub partition MON, TUE, WED, THU, FRI, SAT, SUN
Partion IA
Sub partition MON, TUE, WED, THU, FRI, SAT, SUN
Now i want to perform following tasks.
1. Need to truncate TUE sub partiion on TX partition.
2. Need to truncate WED sub partiion on CA partition.
3. Need to truncate SUN sub partiion on IA partition.
How do we do this?
The below statment truncate all TUE partition on all the partitions.
ALTER TABLE TRX_TABLE
TRUNCATE SUBPARTITION TUE;
How do i tuncate specfic sub partition on specific partition?
I 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.
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?
How to truncate the partition based on the given input. I've below table partitioned on dt field. How can i truncate the whole partition which contain the date 2013/04/30.

I Know we can create dynamic partitions on table in oracle 11g. Is it possible to create normal partition and sub partition both dynamically.I have to create Normal partition range on date and sub partition list on Batch ID (varchar).
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
Can I add range sub partition to a hash partition table. Example like this.
CREATE TABLE test ( test_id VARCHAR2(10 ) , test_TYPE VARCHAR2(5) , CREATE_DATE date ) partition by hash (test_id, test_type) Partitions 3 SUBPARTITION BY RANGE (CREATE_DATE);
When Tried, I am getting syntax error as invalid option.
Activity Structure ACTIVITY_TYPE CHAR (1) NOT NULL, ACTIVITY_DATE DATE DEFAULT sysdate NOT NULL, ACTIVITY_ON VARCHAR2 (30) NOT NULL, REFERENCE_NO VARCHAR2 (19), CHILD_REFERENCE_NO VARCHAR2 (19), USER_ID VARCHAR2 (30) DEFAULT user NOT NULL, TERMINAL VARCHAR2 (30) DEFAULT userenv ('TERMINAL') NOT NULL )
Activity1 Structure Which I have Done Partitioning When I insert data from Activity to Activity1 it gives that error ORA-14400: inserted partition key does not map to any partition what I am doing wrong
CREATE TABLE ACTIVITY1( ACTIVITY_TYPE CHAR (1) NOT NULL, ACTIVITY_DATE DATE DEFAULT sysdate NOT NULL, ACTIVITY_ON VARCHAR2 (30) NOT NULL, REFERENCE_NO VARCHAR2 (19),
[code]....
Insert Statement
insert into ACTIVITY1(ACTIVITY_TYPE, ACTIVITY_DATE, ACTIVITY_ON, REFERENCE_NO, CHILD_REFERENCE_NO,
I have partition based table one the basis of year month. And we have 8 local indexes on this table. Every month we have to create a new partition and load data into this partition and the volume of the data is around 14million and the load process is taking long time due to indexes. Is it possible to drop the indexes from particular partition?
When I am trying to insert record from tbl_mittal into tbl_temp table. I am facing "ORA-14400: inserted partition key does not map to any partition" error
SQL> insert into tbl_temp select * from tbl_mittal; insert into tbl_temp select * from tbl_mittal * ERROR at line 1: ORA-14400: inserted partition key does not map to any partition
AS tbl_mittal is having hugh number of records so I am providing only few rows from tbl_mittal table as test data.
For the above data set i need to divide into 5 partittions and need to updated the partitonid with the partition number for each partition set,like the below result set
How to find the size pf a partition in a partition table?I guess we need to query views like dba_tab_partitions but I am not very sure. will running dbms_stats.gather_table_stats('schema_name,'table_name,'partition_name')
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)
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.. 2) What will be best method to truncate a Table having Master detail relation (Foreign key enabled) and we need to truncate the table without disabling the constraint ( if there are records in child table) 3) What will be best method to truncate a Table having Master detail relation (Foreign key enabled) and we need to truncate the table without disabling the constraint ( if there are NO records in child table
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.
currently developing a app for MSM in tromsø, that are going to delete the oldest entrys in the database table and then update all the relative Run history entrys in another table.
And i can't get the coding right to truncate the old entrys.Here are the
