I have a table A which has million records, and one of the column is a date. All records prior to 01-FEB-2009 should be deleted.
I cannot run the below code considering the amount of records or rows in the table A.
Begin
Delete from A where trunc(date_column) < '01-FEB-2009';
commit;
End;
where we can delete the rows prior to 01-FEB-2009 and also have a total count of how many were deleted?
I like to increase speed to delete our table. Is it possible to use BULK COLLECT or FORALL this query? This is not single delete or select, maybe I got the error? Is it possible to use BULK method to this query?

Is there any defined record count range for the following ways of bulk insert :
INSERT INTO ABCTEMP SELECT * FROM DEFTEMP;
OR
through a cursor, bulk fetch and bulk insert under a loop.
I would like to give back to the our application user a page of results for a given query along with the total result count, something like: "Showing 1-25 of 650 total results".
Currently I am doing this by submitting a second query:
select count(*) from (<previous query criteria>)
Is there a better performing approach I could be using?
I need to modify my query so that it can give me a total(duration) and total(stlmntcharge) per day in april 2013 starting from the 1st till the 30th. At the moment my query looks like below:
SELECT sum(duration),sum(stlmntcharge)
FROM voipcdr
WHERE (calldate >= TO_DATE('20130401','YYYYMMDD') AND calldate <= TO_DATE('20130430','YYMMDD'))
AND (remtrunkid IN (SELECT UNIQUE trunkid FROM trunks WHERE description LIKE '%Telkom%' AND gw_range_id = '61' AND trunkid like '9%'))
or remip in(SELECT UNIQUE startip FROM gateways WHERE rangename LIKE 'vo-za%' OR rangename LIKE 'PC-IS-VOIS%')
AND direction = 'I'
ORDER BY calldate, calltime;
i need the total of the count query I am executing.My query is
SELECT COUNT(*) FROM po_headers WHERE
CREATION_DATE BETWEEN '01-MAR-2010' and '31-MAR-2010' GROUP BY VENDOR_ID
this gives output as
6

My objective is to find the total of distinct vendors for a given date range.how should I modify this query.
We have a front end that is polling the database for some set of data.That set of data is returned by opening a ref cursor and passing it back to the calling environment.Now the problem they also want the count of total number of records that will be fetched by my select statement.One option is execute the select statement once ,get the count and pass it.But in that case i will be executuing the query twice once for count other time while openimng for the ref cursor .
View 7 Replies View RelatedI want to know that whether we can write a query to add total number of count of each table.
for example:
select count(*) from emp;
count(*)
14
select count(*) from emp_1;
count(*)
15
select count(*) from emp_2;
count(*)
16
My question is that is it possible to add this all the three results and get the value as 45.
Im a oracle pl/sql developer but I didnt learn oracle as a language. With my sql skills I started working on Oracle.In my project every table has an associated MLOG$ table for it.
For eg.
CREATE TABLE MLOG$_TEST
(
ID VARCHAR2(64 BYTE),
SNAPTIME$$ DATE,
DMLTYPE$$ VARCHAR2(1 BYTE),
OLD_NEW$$ VARCHAR2(1 BYTE),
CHANGE_VECTOR$$ RAW(255)
)
So is MLOG$_TEST oracle's internal table.
Whenever an insert/update/delete happens it is recorded in MLOG$ tables as I/U/D for the priamry key.So if I do a bulk delete of records in tables an entry is made into MLOG$ tables. So deleting old records in a database doesn't free much space.If this is oracle internal table is it advisable to delete from MLOG$ tables too.
My oracle database is mounted on the Linux server.If I delete bulk records in tables from which path I can see how much space is freed.
I am new to oracle programming.

I'm using this code, and it performs fine, but I'm wondering if there is a more elegant way to do it--maybe with "ROLLBACK". Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )
select
c.Event,
c.code,
count(1) as calls,
total.total_count,
count(1) / total.total_count * 100 as pct_of_total
from
table1 c

I have one table that have many records. For the maintenance purpose I like to delete old record based on Customer No.-That is Mobile NO.If each Customer have more than 300 records, I like to delete by everyday batch process.can't figure out how to apply each Customer No.(Specific Column), I could sort (order by few column - SAVE_DT or SMS_ARV_CLC) how to write this kind of query? I try rownum but no more progress.
Here is my table

View 9 Replies View RelatedWhen we execute select count(*) from table_name it returns the number of rows.
What does count(1) do? What does 1 signifies over here? Is this same as count(*) as it gives the same result on execution?
difference between count(1) and count(*). As i know count(*) will give number of rows irrespective of null and count(1) will not count the null.My Oracle version is 10 g.

What is Bulk COllect and How it can be use
View 2 Replies View RelatedI made two runs for bulk insertion

I have performance issue with the bulk update. I have 2 tables one with 21 millions of data and the other table with 2 millions of data.here the requirement is to update the table which is having 21 millions with the other tables data(which is having 2 million records) based on some matching criteria.
The procedure is taking 9 hours to update the table(which is having 21 millions data). I have created required indexes on table also.But the performance is not good.
Here my procedure:
CREATE OR REPLACE PROCEDURE AHM_GKPR.CLAIMS_WITHOUT_PARTITIONS

I have a driver table from which I need to update another table while, at the same time, record the fact that I have processed each record on the driver table.
The driver table will contain around 3.5 million records, therefore I intended to handle this using some bulk collections, with a LIMIT option so that I don't hit any memory problems.
I would also prefer to commit in batches, or at least handle exceptions using the SAVE EXCEPTION clause. The problem is I seem to be running into an error when trying to make the update to the driver table (the commented out code). With this in, I get the error:
ORA-01410: invalid ROWID
ORA-06512: at "CUST_MAIL_UPDATE", line 217
ORA-06512: at line 38
Can the CURRENT OF not work with the FORALL? What is my best approach here? If I use a FOR LOOP I lose my SAVE EXCEPTIONS exception handling.
The Procedure is as follows:
-- declare some object structures to hold the retrieved data
TYPE driver_rec IS RECORD (
account_no ext_driver.account_no%TYPE,
update_action ext_driver.update_action%TYPE,
customers_rowid ext_driver.customers_rowid%TYPE);
TYPE driver_recs_tt IS TABLE OF driver_rec;
-- cursor to get the records from the driver table

I'm able to run the program successfully using FOR LOOP instead of BULK COLLECT but wish to run using bulk collect.
Okay I am not asking for detailed solution here but I have quick query.
One of the procedure have this cursor query returning say 10 columns and have declared an collection of that cursor type.
Now the cursor is bulk fetched in the collection.
By any means it is possible to happen that bulk collection will scramble column values ?
The cursor seem to return expected output. But when table insert happens using the collection there I see values are mismatched.
I was wondering if bulk collect can be an issue ?
We are doing a bulk select and insert (10,000 rows processed in each transaction). If one record fails, the entire transaction is rolled out. We need to fix this and re-run. the process is repeated unless all errors are fixed.
How to capture all errors in a single run ?
I have the following questions you can create a bulk collect in which he has 3 fields and one of them is a type collect failing index or other bulk collect?.If so, how would the procedure for when to insert the first record sub fill the bulk collect. being for example something like this:

index | codigo | nombre | telefono

| index | telefono
