i have to divide into 3 groups and take a count 7am-12pm, 12pm-7pm, 7pm-7am groups
It looks so complicated to me, because IN time and OUT time together how we do it.
suppose one person 6am IN and out 8PM means he will be in 7am-noon , noon to 7pm, 7pm-7am -- 1, 1 1 on 3 interval another scenario is if one person in 2am in the morning it has to be previous days count. Is this possible to do it in query.

I'm having trouble using interval data types in a procedure. I need to pass a number of minutes as a parameter, and then use them for arithmetic on a timestamp with time zone. This works no problem:
set serveroutput on
create or replace procedure tstz(mins varchar)
as begin
dbms_output.put_line(systimestamp - interval '10' minute);
end;
[code]...
I've tried a few variations of data type and type casting for the parameter, but I can't make it work.

how to create a view from table which containes rows from every minutes. In view I want to select only rows at 15 or 30 minutes interval.
eg. my base table has 60 rows for 1 hour. The created view must contain 4 rows on 15 minutes interval basis at the boundary of that interval.
O/P of view should be like this.

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.

I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?

Refer to the txt file to create table and insert data.
I executed the following query-
SELECT priority, detail, COUNT(1) FROM TEST GROUP BY priority, detail
and got the following result-
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial TSS 1
StandardInitial development 10
StandardProduction deployment5
High PriorPatch 1
Now I want that Initial TSS and Initial development should be combined as Initial together and I should get the result as follows:
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial 11
StandardProduction deployment5
High PriorPatch 1

I have created a job using DBMS_SCHEDULER and I want it to run every 30 seconds:
begin
dbms_scheduler.create_job(job_name => 'jobu',
job_type => 'PLSQL_BLOCK',
[Code]....
My question is how can I take the value 30 from a configuration table? Let's say I have a query like select value from config_table where property = 'job_interval' that returns the number 30. How can I set this value to be the repeat interval for my job?

I have one page with an interactive report (Page 10) and another with a form to update each entry (Page 20).
The table that these pages refer to have a column called MY_INTERVAL_COL of type INTERVAL DAYS TO SECONDS.
I can successfully display the contents of MY_INTERVAL_COL by extracting DAYS, MINUTES, and SECONDS on Page 10:
TO_CHAR(EXTRACT(DAY FROM MY_INTERVAL_COL)) AS MY_DAYS,
TO_CHAR(EXTRACT(HOUR FROM MY_INTERVAL_COL)) AS MY_HOURS,
TO_CHAR(EXTRACT(MINUTE FROM MY_INTERVAL_COL)) AS MY_MINUTES,
However, the Automated Row Fetch process appears to ignore columns of type INTERVAL DAYS TO SECONDS on Page 20.
:P20_INTERVAL (database column MY_INTERVAL_COL is used)
:P20_DAYS (trying to convert :P20_INTERVAL using TO_CHAR(EXTRACT(DAY...
:P20_HOURS (and so on...)
:P20_MINUTES
Does Automated Row Fetch ignore columns of type INTERVAL DAYS TO SECONDS?

Other than the obvious to me, where interval partitioning creates partitions as needed. Is there any performance benefit from using interval partitions vs date range partitions.
One draw back for me is that developers do access the partition name in some of their queries, so if I use date range partitioning this will not break their code. I could not find a way to assign a name to a partition when using intervals, is this always system generated or can this be over-ridden.
I am running Oracle 11.1.0.7 soon to be running on 11.2.0.0

We have a table like below.
Create table Item_max
(
CCN varchar2(10),
Run_date date,
Item varchar2(10),
status varchar2(1)
[code].....
Currently we are inserting the cycle data for all Items every day into above table for all the CCN's.Currently there are 100k Items in our DB and gets inserted every day into above table with Different Rundates for all CCN's.
We need the above data for 6months and we would like to purge the data based on the RunDates.
We thought of creating a Partition on CCN and Interval Subpartition on Run_date with Interval of every 1 day but I could get any materials on the net to have List-Interval partitioning in Oracle 11G.
Also List - Range partitioning doesnt work here as the Dynamic partition used(using Maxused) will contain the data for all Run_dates instead of particular rundate.

I have this requirement to pull the ACTIVE days that a participant holds true in a given month for a specific position he/she holds.The three date ranges here are: LOA dates(leave of absence), XFER dates(TRANSFER in/out of the position),Quality compliance(QUAL start/end dates).So,
INACTIVE DAYS = [(LOA + XFER + WW) - OVERLAPPING DAYS OF (LOA+XFER+QUAL)]
CREATE TABLE PAYEES
(
RUN_PERIOD DATE NOT NULL,
PAYEEID VARCHAR2(20 BYTE) NOT NULL,
LOA_START_DATE DATE,
LOA_END_DATE DATE,
[code]....
I am able to pull out the no of days on a individual basis(count of days for Xfer/LOA/Qual) but I am really not sure as to how should i go about determining the overlapping days between 3 date ranges to determine the ACTIVE/INactive days.

Let's say I have this table:
create table TEST
(
CF VARCHAR2(16),
START_DATE DATE,
END_DATE DATE
)
with
insert into test (CF, START_DATE, END_DATE)
values ('ME', to_date('01-01-2011', 'dd-mm-yyyy'), to_date('31-12-2010', 'dd-mm-yyyy'));
I need make a select where I get n rows, where n is the number of trimesters that compose the date interval in the table. Each of the returned rows must have as start_date/end_date the boundaries of that trimester.(ALL start dates are the first day of a month, and all end dates are the last day of a month)
In this case I need to get:
ME - 01/01/2010 - 31/03/2010
ME - 01/04/2010 - 30/06/2010
ME - 01/07/2010 - 30/09/2010
ME - 01/10/2010 - 31/12/2010

When I connect to a Oracle database(remote) using TOAD client, because of the settings of timeout done at the server end(in Oracle), the TOAD session gets time out in 5 minutes.
I want to know how I can increase the timeout interval or if I can keep on pinging the database server so that the TOAD connection does not gets timeout?
PS: When we connect to a unix server using putty, we can keep on pining the server at regular timeout interval by going to Change Settings->Connection->Set KeepAlive
Is there a similar way for TOAD?
