when I am executing the below query getting diffrent count every time and not able to guess what is happening.
SELECT
count(1)
FROM table1 where table1.LAST_UPDATE_DATE >= current_date - interval '9' day
I am looking to simplify the below query,
DELETE FROM A WHERE A1 IN (SELECT ID FROM B WHERE BID=0) OR A2 IN (SELECT ID FROM B WHERE BID=0)
Since both the inner queries are same,I want to extract out to a local variable and then use it.
Say,
Array var = SELECT ID FROM B WHERE BID=0;
And then ,
DELETE FROM A WHERE A1 IN (var) OR A2 IN (var)
How to do this using SQLPLUS?
I want to know that is there any way to know the execution time of a sql query.

View 16 Replies View RelatedI have the below query for which ename column has an index. As of my knowledge below queries 1st and 2st will not use index. Hence i used the 3rd statement and that too its not using the index. Finally i used the 4th query, but even the 4th query is not using the index. Then how do i make this query to use my index??? Do i need to create a function based index for this?
1. select * from emp where ename !='BH' ;
2. select * from emp where ename <> 'BH';
3. select * from emp where ename not in ('BH');
4. select * from emp where ename < 'BH' or ename > 'BH';
I am facing a very strange issue with one of our Oracle query. The query is usually completes in a minute or two. Even the execution plan of the query is good and it works perfect most of the times, as expected. The query fetches about 1000-2000 records each day.
But on a given day, the query takes about 30-40 mins to execute completely. Upon checking the load on DB server, there are no other processes running which can impact the run time of this query. Moreover, the record counts fetched are almost same as compared to other days. There is no pattern observed as that this phenomenon occurs. it all happens once in a while.
Configuration is Oracle 10g with RAC environment on LINUX
I am executing the query below:
INSERT INTO temp_vendor(vendor_record_seq_no,checksum,rownumber,transaction_type,iu_flag)
SELECT /*+ USE_NL ( vd1 ,vd2 ,vd3 ) leading ( vd1 ,vd2 ,vd3 , tvd) */ vd1.vendor_record_seq_no, tvr.checksum, tvr.rownumber, tvr.transaction_type, 'U'
FROM vendor_data vd1,
vendor_data vd2,
vendor_data vd3,
(SELECT rownumber,
[code]....
It is taking different approaches (execution plans) while executing for same set of parameters. Due to which sometimes it executes successfully, but sometimes it fills all TEMP space and get failed. I am pasting both the execution plan (different from expalin plan) below:
I. Successfull Execution Plan:
------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
------------------------------------------------------------------------------------------------------------------------
| 0 | INSERT STATEMENT | | | | 65612 (100)| | | |
|* 1 | HASH JOIN | | 1 | 6121 | 65612 (1)| 00:13:08 | | |
[code]....
II. Failed with TEMP space Execution Plan:
--------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
--------------------------------------------------------------------------------------------------------------------------
| 0 | INSERT STATEMENT | | | | 1967 (100)| | | |

I want to run below query to get the result set that I am after. But It takes long time even with the indexes...Here in IM_Mapping table is having 1.7 mio records and T_Extract table about 35000 records. All the other tables having below 1000 records

Just want to know if there is any possibility of running the query with all the Groups in one go
Even if I run group wise it took 30 min query still running without any results...Is there anyway of restructuring the query for better performance.
My scenario is something like this:
MyTable
Rownum Colval
1 23
2 34
3 45
I need to write a query which will get me output: 233445, i.e. all the three rows concatenated. How can it be done? I want to do it through sql only and not to use PL/SQL. Is this possible?
I have a sql query which fetch the data from 4 different tables. I want to write the output of that query into a excel or a CSV file without using TOad and all. Let me know is it possible via creating function or procedure.
