How can check that which query is taking how much load or time in execution on server in oracle.I want the soluation as like that, run the query and get the detail in desc order and identify that this query is required to tune or kill the session.
View 1 RepliesIn my table ,data type of one among 10 columns is defined as varchar2(10).I need to check that column should accept only numeric value(0 to 99) or alphabetic value(a to z or A to Z) .It should not accept Alpha-numeric values.I tried like this
select c3 from demotab where to_number(c3) not between ascii('a') and ascii('z') ;
but I got error like 'Invalid Number'.how to implement this thro sql query.
1) I got column date of joining which accepts date in below format DD-MON-YYYYDD-MON-YYMON-DD-YYYYMON-DD-YYMonth DD,YYYY Question:-
how do i check whether all dates in Date of joining column are in above format or not using sql query? 2) I got one more date column which accepts date in below formatMMDDYYYYYYYYMMDDMM/DD/YYYYMM/DD/YYYYYY/DD/MM Question:-
how do i check whether all dates in date column are in above format or not using sql query?
I have a table and data as below.I need to select all the records if value have both 'M' and 'D'.If there is only 'M' or 'D' then select should not pull any records.
WITH data as (
Select '1' id, 'M' value from dual union all
Select '1' id, 'M' value from dual union all
Select '1' id, 'D' value from dual union all
Select '1' id, 'D' value from dual )
select value from data group by value
I tried below query but it is not working.
WITH data as (
Select '1' id, 'M' value from dual union all
Select '1' id, 'M' value from dual union all
Select '1' id, 'D' value from dual union all
Select '1' id, 'D' value from dual )
select * from data group by value having sum(count(distinct(value))) > 1
Our production DB version is 11.2.0.1 and we do use DBArtisian. Everyday morning we check table space usage using that tool and it generates the below listed query. It used to run in 15 secs. But since one week it is running for 5/6/8 mins. I have updated the statistics on sys objects and tuning advisor created the execution plan. So, now it is running in 2 mins. Nothing has been changed in the DB configuration. I see the same query running in secs in dev environment. understand what might be the issue and how could I improve the performance of this query.
SELECT SUB.TABLESPACE_NAME, SUB.STATUS, SUB.EXTENT_MANAGEMENT, SUB.SEGMENT_SPACE_MANAGEMENT, SUB.TOTAL_SPACE_MB, SUB.USED_SPACE_MB, SUB.FREE_SPACE_MB, SUB.PERCENT_FREE_SPACE, SUB.CONTENTS, SUB.TABLESPACE_GROUP, CASE WHEN SUB.TABLESPACE_NAME = P.VALUE AND SUB.CONTENTS = 'UNDO' THEN 'YES' ELSE 'NO' END

We need to do load testing on our DB before going live. Mainly with 5 queries which are mainly used in our web interface to pull data from the database. For example. I need to send morethan 400-500 sessions to our database using this 5 queries (with different values) and to note down the time taken with every 50 number of users..
I have a big table in which we load about 37M recrods. We have informatica ETL which Loads the data in bulk Mode and creats index after completion. The data load takes about 1Hr and Index Creation takes about 1/2 hr. In total it takes about 90 to 95 Mnts.
Now I thought if Partition and Load paralley, It will improve perfromance. We did 4 partition and and each Partition about 9M records. The data load in Bulk mode is completing in 25 Mnts. Again When I am creating index over it, It is taking about 40 Mnts. and in Total Load time is 65 Mnts.
Is there way I can better performance to complete the load in 1/2 hr ?
i have tried it , but it load the data in text file , but i want to load this data in excel sheet in such a way that each column should be in different-2 cell of excel sheet.

I am on APEX 4.1.1, db 11g and I have a report which is quite slow to retrieve results from its query. The page has some filter fields (e.g. store code, dept code) in addition to the generic search field.
When the user lands on this page (from a menu page), the query runs before the page displays and this typically takes 1-2 mins without any filters yet set. The usual browser loading indicators are not obvious to the user and they might not be aware that it is working on the request.
I want it so that it will only run the query AFTER allowing the user to get to the page, let the user fill in some filter criteria and then click on the GO button. Therefore the query will run after the page is submitted. When you hit the GO button on the interactive report, a nice rotating apex_loader.gif appears, making it obvious to the user that it is working on the request.
I would prefer NOT to create 2 pages, one for user filter, and a second for the actual report as I have many reports/inquiries which fit this category and I would prefer NOT to have to create pairs of pages for each.
We have a problem where a data load script has caused data in one of our tables to be incorrectly loaded. Instead of loading the parent row, it has loaded an offest that was assigned by the application.
The problems is, we have the following table:
=================================
ID RESULTSET PARENT
=================================
...
100 502 -1
101 502 0
102 502 1
103 502 2
104 502 3
105 503 -1
106 503 0
110 503 1
111 504 0
...
=================================
What's the best approach to use to transform the last column as follows:
=================================
ID RESULTSET PARENT
=================================
...
100 502 99
101 502 100
102 502 101
103 502 102
104 502 103
105 503 104
106 503 105
110 503 106
111 504 110
...
=================================
Note: ID column may not always be ordered sequentially

I want to ask for a password from the user so they can access their account, however I want the password to have constraints on it. For example I want the user input to between 6 and 12 characters in length containing at least one number and one letter.
View 2 Replies View RelatedMy goal is this:I have a table which is being updated/changed by lay people with certain types of values. Constraints are given to them, but they need not conform to them as they update the table in excel.Now, I want to validate this table every-time before I use it. i.e. implement a script which can be run to verify is all the values are in the right format for further usage.
I have a variable number of columns (i.e. users can add further columns as their requirements change).From columns 3 to 'n' (depending on table given) the values should be 'Yes' or 'No'. How do I check this for a variable number of columns in PL/SQL?

vnum number;

if vnum>0 then
execute immediate 'drop table '||vname;
dbms_output.put_line('table dropped');

My requirement is like when I am calling the procedure P1 with some values then it should check the table "t2".And table "t2" is linking with table "t3".
So what ever the column "verify" is there, it should check the incoming values against it. If matches success otherwise reject it.Later the incoming values is stored different tables.I am doing it in the above way by hard coding some value.
BEGIN
p1(1,'MILLER',500,'ADMIN'); --REJECT
p1(1,'MILLER',5000,'ADMIN'); --ACCEPT
P1(2,'MILLER',5000,'SALESMAN');--ACCEPT
END;
I am select list of ids;
cursor c1 is
select c_id from ctab1 where login = l_id
union
select c_id from ctab2 where login = i_id;
now I need to return err_code and err_message if this combined list is empty ! Can not use exit%notfound.

now my output should be as above because GHI is common in both the names.if any of the where condition string matches the Name field then I need that record to be retrieved.
I have made a simple form in which user will be entering his username and relevant password to get authorised.

This is the description for the procedure:
ADD_REWARD_sp. Given the identifier of a project, add a new reward for the project. The procedure should return a unique identifier for the reward. The month and year indicated should be greater than or equal to the current month, or an error message should be generated. The pledge amount should be greater than zero. The number of backers, if not NULL, should be greater than 1. If the project is not found, generate an error message.
This is the procedure head:
create or replace
PROCEDURE ADD_REWARD_sp(
p_proj_id IN NUMBER,
p_pledgeAmt IN NUMBER,
p_rewardDesc IN VARCHAR2,

Basically, what I am struggling with is how to check if th month and year is greater than or equal to current month. I suppose it would be easy with just checking SYSDATE, but in this case I need to use both month and year.
URL....Topic: The Execution Model for Triggers and Integrity Constraint Checking
Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking:
1.Run all BEFORE statement triggers that apply to the statement.
2.Loop for each row affected by the SQL statement.
a.Run all BEFORE row triggers that apply to the statement.
b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
c.Run all AFTER row triggers that apply to the statement.
3.Complete deferred integrity constraint checking.
4.Run all AFTER statement triggers that apply to the statement.
i have an understanding about Integrity constraint checking and the trigger execution sequence, which i decsribe below.
Integrity constraint are restiction on DML operation performed by the user. When a user deletes or updates or inserts a rows in a table then oracle performs certain checking to see that the data which is effecting the row abide certain rules. There are certain per-defined set or rules that can be applied on a table such as PRIMARY KEY, FORIEGN KEY, UNIQUE, CHECK, NOT NULL etc, user-defined rules can be applied on tables by using Triggers.
In both the cases the Integrity Constraint Checking is deferred until the complete execution of the statement. All rows are inserted first, then all rows are checked for constraint violations.
So when i see the trigger execution model the following steps are performed by oracle, Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking..This is what the Oracle Documentation Library says [extract from Oracle Database Concepts 10g Release 1 (10.1)].
1. Run all BEFORE statement triggers that apply to the statement.
2. Loop for each row affected by the SQL statement.
a.Run all BEFORE row triggers that apply to the statement.
b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
c.Run all AFTER row triggers that apply to the statement.
3.Complete deferred integrity constraint checking.
4.Run all AFTER statement triggers that apply to the statement.
As for step 3 here the checking of the constraints for the statement is performed which where defered till the complete execution of the statement, then what is done in step 2b? what constraints are checked there?
I've installed GI 11.2.0.3 on AIX 7.1.And today I noticed strange ASM's behavior:
-bash-3.2$ getconf DISK_SIZE /dev/rhdisk2

I guessed that was because of LUN size (it was exceed 2 TB)After that I dinamically shrinked LUN size on our external storage, rebooted and perfomed cfgmgr command on both nodes. But I still have no enough free space.
