I have a table with starting date and ending date.
I want to fetch monthwise days for given two dates
IE starting 25/12/2009 ending 25/03/2010
Result should like below.
Dec-09 7 Jan-10 31 Feb-10 28 Mar-10 25
I have tried this but it is not giving me the result which want..
select to_char(thedate,'mon-yy') mnth,count(to_char(thedate,'mon-yy')) days from (SELECT TRUNC(to_date('25/12/2009','dd/mm/yyyy'),'Y')+ROWNUM-1 THEDATE FROM ( SELECT 1 just_a_column FROM dual CONNECT BY LEVEL <= 366
I have installed Oracle Database 11g.2 by database configuration assistant on windows XP as and adminstrator on my laptop(no connection to network),but when I want to create database I face this warning: error securing database control ,Datatbase control has been brought up in non-secure mode . to secure the database conntrol execute following command....(error is attached).
I'm planning to use one Instance of ASM to manage 2 11gR2 RDBMS database in a single server. Each RDBMS will have distinct ORACLE_HOME, OS user and group.
ASM will also have a separate ORACLE_HOME, OS user and group for maintenance purpose.
Based on this configuration, who should own the Raw disks? I am not going to use ASMLib because of the dependancy it creates with the Linux kernel?I just don't want to waste time with test and trial as the server are managed by sys admin.
I have successfully set up a (test) environment for single-instance Grid Infrastructure and Oracle database using job role separation. So I have the recommended grid and oracle users, and the oinstall, dba, oper, asmadmin, asmdba and asmoper groups. I have the following directory structure for my Oracle Bases and Oracle Homes:
/u01/app/11.2.0/grid - GI home /u01/app/grid - GI base /u01/app/oracle - DB base /u01/app/oracle/product/11.2.0/db_1 - DB home
Platform is OEL5, 11.2.0.1 GI and DB.
This all works fine.
What I now want to do (since what I'm trying to do is make this environment as secure as practical) is set up an additional sysoper operating system account, so that that user can connect to carry out sysoper tasks, amongst other things stopping and starting the instance.
So (as the oracle user) I do the following:
$ sqlplus / as sysdba SQL> create user test identified by passwrod; SQL> grant sysoper to test; SQL> exit
As you can see, shutdown works, but startup doesn't. I have registered an SR with Oracle on this, but they're not being useful. The suggestion was that I should give testoper the to install secondary group. But this is not a secure solution as this now gives testoper privileges to do things in OB / OH that it really shouldn't be able to do. No other suggestions have been forthcoming. The reason for the suggestion however is the ownership / permissions on the Grid OH oracle executable:
[root@db03 ~]# ls -la /u01/app/11.2.0/grid/bin/oracle -rwsr-s--x 1 grid oinstall 184286237 Aug 22 11:15 /u01/app/11.2.0/grid/bin/oracle
As you can see, it has group oinstall, so you can see why giving the user oinstall group would work. But in my view this is not satisfactory.
One thing that occurred to me is that in this environment I should arguably in fact be using srvctl to stop / start instances. But that means setting up a user with asmoper role (presumably) rather than oper. That user would then (again presumable) be able to stop and start other GI resources, which is not what I want.
I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID", LOC_ID AS "LOCATION ID", TEST_DATE AS "DATE", TEST_TIME AS "TIME" FROM MON_TEST_MASTER WHERE AREA_ID =89 AND LOC_ID ='3015' AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
In oracle query can i want find out how many day wise count for a year days (for example how may sundays, mondays, tuesdays, wednesdays ,thursdays,fridays,saturdays) in a given year (we can give the start day of the year and the end day of a year).
example ---------- jan sun-5 mon-4 tue-5 wed-5 thu-5 fri-4 sat-5 feb ------------do--------------------------------- like this for all 12 months at a single query.
select in1.empid,in1.atttime,out.atttime from (select empid ,atttime from attend where status=1 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) in1, (select empid,atttime from attend where status =0 and to_char(atttime,'mmyyyy')='022012' order by empid,atttime desc) out where in1.empid=out.empid and in1.empid='02256' order by in1.atttime,out.atttime
But this query do .one value relation with all column.means first february in time with all out time.
If a particular department has 10 employees it should have data upto emp_name_10,if department has only 5 employess it should data upto emp_name_5 and so on.I came up with below approach, in this approach I need to create new table to store the data in row wise.
In my actual requirement 4 tables needs to be joined and 2 of the tables are very large.Is there any other approach without creating a new table, something within pl/sql.
drop table emp_dept; create table emp_dept(deptno number,dept_name varchar2(100),emp_name varchar2(100),hire_date date,seq_cnt number,total_cnt number); insert into emp_dept
OS : Windows 2003 DB : 10.2.0.4 I am doing capture and replay first time.I want to take 2 captures at a time. 1st capture for 2 schemas and 2nd capture for other schemas.Is it possible?I have searched on internet but didn't get any clue about it..
Web page that retrives data from SQL database and display it to the user in well formatted manner. Data retrieved depend upon criterias selected by the user. But sometimes data retrieved is very large. I want to display records to the user page wise, i.e. 100 records on first page and next 100 records displayed when user clicks next button. This means only 100 records should be retrieved when user first select search criteria, next 100 records retrived when he clicks next button and so on, as to reduce data transferred from server to client. how to achieve this by using single sql query as soon as possible.

how can i compute row wise multiplication for each unique value of id. I am trying to get the output as showing id and their respective results after multiplying the corresponding values.
CREATE TABLE mult_tbl( id NUMBER, val number ); insert all into mult_tbl values (1,2) into mult_tbl values (1,3)
Is there any way to capture the version wise objects (Packages) information from the oracle data base.
Ex : I have package P1 which was created on 01-NOV-2012 with version 1 . After 10 days same package has been updated version 2 with some enhancements.Like that the package will be updated according to the latest requirement.
Now I need to capture the total audit trail history of the package with version wise specific changes and when changes has been occurred hoe can I achieve this?
according to me, v$datafile can be use to know growth in database in terms of datafiles added in past months as per creation_time. but hows about those existing datafiles whose size has been re size more .
how to tune qurey for coulumn wise data saved.because we have to join same table n number of times.for reference go through the following scnarios.
Suppose one table T1 is there and it has two column KEY and VALUE.if we are writing qurey for retriving desire result in row manner we have to join samae table no of times.
KEY Value agreesWith true id 1 assessment False basisForDateOfProgression 1 bestOverallResponse 2 bestOverallUnknownComments data is ok
Qurey:
select * from ( select t.agreesWith from t1 t )a
[Code]...
In this manner we can join upto bestOverallUnknownComments .so which method we follow to reduce the execution time and performance should be good.
