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.
just wanted to know if i create a table with 1000 columns, and use only few of them and remaining are for future use, will it affect the performance and storage?

I have a table in schema with a BLOB field. I store employee's picture in this field. Fields in this table are emp_id (number) emp_name (varchar2) and emp_photo (BLOB). I want to ask if there is a way in pl / sql that i could empty this BLOB field to null or reset this field so that user can change the saved photo graph and save another one.
what i am looking for is something like
alter table employee set emp_photo = empty_blob() or alter table employee set emp_photo = null
May I have a PL/SQL program that can update 1000 rows.
View 4 Replies View RelatedI am trying to run the following query below in Oracle:
Select Acct_Num, Customer_Name
From Database
Where Acct_Num IN (
1,
4,
104
..,
..,
192384,
200002
)
When I attempt to run the query, I get the error message: "ORA-01795 maximum number of expressions in a list is 1000"
Is there any way I can execute this query w/o having to break the 'IN' list up by 1,000 Acct_Num over numerous amount of times? I know the 50,000+ accounts I want the info on but they are not ordered and they mix ranges with accounts I don't want. Therefore I can't use a 'BETWEEN' clause. Also, I don't have the ability to create a temp table.
I have an app that reads records from a driver table in order to update another (account) table. The idea is that it runs quickly but does not impact other processes on the system. In total I have around 1M records to update.
Originally I wanted to BULK COLLECT and employ a LIMIT of 1000 with a FORALL. The problem with this approach though is that I make two updates. One to the target table but I also need to update the driver table showing that I have processed the record. Therefore I cannot use this option to commit every time I reach the LIMIT by having a COMMIT inside the LOOP.
So instead I I have a FOR LOOP and test the count, if it is 1000 then I want to commit. I thought this syntax would be fine but I get the 'Fetch Out of Sequence' error. Below is a copy of the code.. Is this being caused by the double update... as the format of the code looks correct to me (though it is late!!)?
PROCEDURE update_set IS
CURSOR cur_get_recs IS
SELECT account_num,
ttw_active_flag,
acct_rowid,
rowid driver_rowid
FROM driver_table

I am taking an example of EMP table in a scott schema.
EMP_1 is also a same structure of EMP.
Here is the Insert statement used.(i might get where clauses etc in the real scenario i am taking a simple example here)
INSERT INTO SCOTT.EMP_1(JOB,ENAME,EMPNO) SELECT JOB,ENAME,EMPNO FROM SCOTT.EMP
table EMP is having around 25 million records.
i would like to do a commit after every 1000 records. as my redo log is getting full if i use a single commit at the end.
Quote:pls note: Increasing of redo log is not possible as of now
is there anyway i can acheive this without cursor bulk collect.
