SQL & PL/SQL :: Calculation On A Time Field?
Jul 5, 2012
I have time fields that have been converted from a 12hr clock to a 24hr clock and these fields hold only the time...no date.
I need to be able to determine the difference between column A and B eg.
Column A: Column B:
11:00 14:00
I can remove the ':' by using the replace command, but as I need to run on a actual 24hr clock I am not sure how to tackle the calculation as it is not the full oracle datetime format.

I want to display Week No as the heading.So, I have these:
define week_no=number
column week_col new_value week_no
select to_number(to_char(sysdate, 'ww')) week_col from dual;
I have tested it and it is working as the way I expected: select 'to display week no as column' "Week &week_no" from dual;
The output:
Week 16
----------------------------
to display week no as column ...So how do I display Week 15, Week 17 etc based on the calculation of &week_no e.g. &week_no+1?

SELECT FROM_TZ(CAST(TO_DATE('1999-12-01 11:00:00',
'YYYY-MM-DD HH:MI:SS') AS TIMESTAMP), 'gmt')
AT TIME ZONE '+05:30' "Time at Time zone"
FROM DUAL;
Time at Time zone
01-DEC-99 04.30.00.000000 PM +05:30
My requirement is that
I want to add 2 hours to DateTime i get here i.e. add two hours in result and display the resultant date and tine in time zone '+05:30'. I also want to check that the resultant time falls in business hours (9 am to 6 pm).

Currently I am working on payroll system where I have to calculate employees working hours/late coming hours/early going hours against its roster which is defined in the beginning of every month/week.
In roster form user define shift of every employee like
Code Name Shift
7 Saad Nafees A - 09:00 17:00
492 Muhammad Nasir Shahzad B - 17:00 01:00
243 Muhammad Tahir C - 01:00 09:00
Roster table structure
code varchar2
name varchar2
Shift date
Remarks varchar2
shift table structure
code varchar2
timein date
timeout date
latetime date
Hdaytime date
Oracle stores both date and time information in date data type, suppose today user change shift timings from 17:00 to 17:30 or user change timein/timeout in attendance form then oracle will store current date with user define timings.
Now this is the main problem which I am facing because whenever you calculate difference between timein and timeout or compare with its roster then output comes wrong because oracle returns total no of hours whenever you minus two dates.

T1 = 06-Jun-2011 4:00PM
T2 = 10-Jun-2011 11:AM
Calculation is Required.
If at the end of Day Hours of T1 > 6 hours then it should calculate 1 Day.
same with T2. hours of T2(from begining of Day till end Time (11AM), it should again caculate if >6 hours then 1 Day.
remaining will be date calculation. this is how T2 - T1 should give us 5 Days.
Detail
06-Jun-2011 4:00PM to 06-Jun-2011 12:00AM (8 hours > 6 = 1 Day)
06-Jun-2011 12:00AM to 07-Jun-2011 12:00AM = (1 Day)
07-Jun-2011 12:00AM to 08-Jun-2011 12:00AM = (1 Day)
08-Jun-2011 12:00AM to 09-Jun-2011 12:00AM = (1 Day)
09-Jun-2011 12:00AM to 10-Jun-2011 12:00AM = (1 Day)
10-Jun-2011 12:00AM to 10-Jun-2011 11:00AM (11 hrs > 6 = 1 Day)
this is how 5Days calculation is required.

Till statspack we had
elapsed time = time spent on waits + time CPU was used
Total time during snaps = Elapsed time + (may be) time waited for CPU...In AWR is it possible to draw such equation? I can see that the AWR report has following elements
1) End Snap time - Begin Snap time
2) DB time - as mentioned at the top of AWR report
3) DB CPU - in "Top 5 Timed Foreground Events" (I assume this is 'CPU used by sesson timing' in statspack)
4) Total of time for all Statistics in "Time Model Statistics"
5) BUSY_TIME + IDLE_TIME - "Operating System Statistics"
Time between 2 snapshots? or what else? Also for which seconds to multiply to 'DB Time(s)' per second and 'DB CPU(s)' per second in Load Profile to get the db time and CPU time?

calculating values of A & B
(both these fields a_std and a_time are coming as varchar from the parent table in a cursor.(basically they are time period and actual arrival time respectively)
i was juggling with the attempt to make varchar to timestamp or date..but caught with Round up /Round down)
Formula ->
A = Round down [A_TIME - A_STD]
B = Round up [A_TIME) - 10 minute + A_STD]
where
A_TIME VARCHAR2(8) N Time (Format" HH:MM AM/PM") eg "3:50 PM"
A_STD VARCHAR2(5) N Standard time (Format" HH:MM") eg "1:00"
Allowed values for A & B after round up/down = multiple of 10 ( 11:00,11:10,11:20 etc.)

I have a field (called Date_Time) which displays for example 1/31/2005 12:00:00 AM. I would like to run a query that converts that value to '200501' in a created field.
I tried the following below but I keep having problems.
select Account_Number, Date_Time,
concat(year(Date_Time), month(Date_Time)) as Date_Time_Modified
from table
where Account_Number = xxxx

I have a display item form field. The field's data type is date. It is also a database field that corresponds to a date field in the table.
I have set the format mask on the form field to
MM/DD/YYYY HH24:MI:SS
I can populate that field with sysdate in when-new-form-instance.
However, if I try to get the date and the time in the field, it just populates the date with the time of 00:00:00.
(02/16/2010 00:00:00 for example).
I have tried several to_char and to_date variations but can't seem to get the current time into that field.

When working in MS Access, I can build parametric queries, where I can input the date field for example at run-time. How can I do something similar in SQL Oracle

WHERE Sector.Date=[Enter Date];

I am having problems with the XMLTable function. I cant get it to see the entire date/time value in a date field. This wont work
select x1.* from XMLTABLE('/DOCUMENT' passing xmltype('<DOCUMENT><STR>abc def ghi</STR><NUM>1234</NUM><DT>2013-02-17T04:24:02</DT></DOCUMENT>') columns STR varchar2(25), NUM number, DT date) x1;
However if I change the DT tag to just the date only "2013-02-17" it works. Why wont Oracle see the entire date/time format even if its ISO 8601 compliant?
Oracle DB: 11.2.0.3.0

Is it possible to calculate cumulatively in oracle sql queries, i.e. using the results of the last row for calculating the values in the current row?For example I want my query to return the following:
Month col1 _ col2 _ col3
jan 1 _ 100 _ 100 * 1
feb 2 _ 200 _ 100 * 2 + 200
mar 3 _ 300 _ 400 * 3 + 300
apr 4 _ 400 _ 1500 * 4 + 400
may 5 _ 500 _ 6400 * 5 + 500
In col3 above, for feb I want to use the result returned for jan ((100 * 1)*2+200), for mar I am using the result returned for feb((100 * 2 + 200) * 3 + 300) and so on.
i.e. I want to use the previous value of column3 to derive the current value of column3. Like using the LAG function but on the analytically derived column itself.

for making the query for following data,when we give start and end date then query need to calculate number of years.
if less than one year then return 0
if exact one year then return 1
if exact 1.5 years (18 months) then return 2

We want to calculate Annual leave the scenerio is as follows
1. Employee service more the one year
2. if joining date is 07-04-2008 than on 07-04-2009 completed one year and on 07-04-2010 completed two years and so on. day and month of date must be the same.
so we need YEAR*14. e.g. if 1 year completed then 1*14 if two years completed then 2*14 and so on. by this we will get the opening of Annual leaves.
We have another table where we entered the leave day by day in whole year, if he avail 10 leaves in first year then 4 will be remaining and we can say it is the closing of first year and opening of second year. so on second year he will entitled 14 more leaves so 14 + 4 = 18 should be opening of next year.In year Caclulation Day and Month must be the same for example 07 day, 04 month for every year. 14 Annual leaves are fix for each year
following are columns for output.
empid, ename, date of joining, sysdate, leave opening, leave avail, closing balance,
1, jone, 29-05-2009, 29-05-2012
2, herry,29-05-2008, 29-05-2012
3, bell, 29-05-2006, 29-05-2012
between two dates (date of joining and system date)

I got 4 fields:
event_date (01/01/1900 hh:mm:ss)
team_count (number)
interview_count (number)
duration (01/01/1900 hh:mm:ss) - duration of each interview
The calculation is:
(interview_count * team_count * duration(hh:mm)) + event_date
i.e.:
(3 * 2 * 02:30) + 01/01/1900 08:00:00
= 15:00:00 + 01/01/1900 08:00:00
= 01/01/1900 23:00:00.
all I care about is the hh:mm in the result.How can I preform this calculation in pl/sql?

I want to write a sql qeuery to get result similar to expected average column as shown in sheet.
Record can be uniquely identified by columns ID, PRODUCT and OFFICE. I want to calculate average for each date considering the same record does not exists earlier i.e. I want to consider the latest vote while calculating average. E.g.
Average till date 1/1/2011 is Avg (2, 4, 3) = 3 (as no repeating vote value exists)
Average till date 2/1/2011 is Avg (4, 3, 5, 3) = 3.75 (excluding vote value 2 as 122_UK_LONDON was provided his vote earlier, so considered latest vote value i.e. 5)
Average till date 3/1/2011 is Avg (3, 5, 3, 6, 5, 8 ) = 5 (excluding vote value 2 for 122_UK_LONDON and vote value 4 for 967_Europe_London)

I'm getting trouble in getting the sum of all the product's prize present in the form fields of invoice form. For example, I user bought 2 products so I want to get there prize sum in the total box. I first want that I've QUANTITY, DISCOUNT and SELLING PRIZE.
If I multiply Quantity with Selling Prize then I gets the result in Product and Quantity Total Box. However, Now I want to add discount option in it. Means if user is providing 10% discount to his/her customer then Quantity * Selling Prize - Discount% becomes a result in product's solution final prize box.
Here is the pic..
Look...Now here..I've added 22 in quantity.. now if I'll insert 10% in discount then the total will comes in Amount Display Box.
I'm currently using this coding on on Prize Box..
:SP_PRODUCT_PTOTAL := NVL(:SP_PRODUCT_QUANTITY,0) * NVL(:SP_PRODUCT_PRIZE,0) * NVL(:SP_PRODUCT_DST,0) / 100;

I have a table where i need to update one field values based on another field of the same table , simply as it is.I have done this using one select all check box , on clicking that all check boxes of item_trans table will get selected , then i will un select some of check box and then using one button, i will update the value of the fields which are checked only.
I have put the sample code but when i am updating its taking long time and hanging.I am also attaching the form based on the test case provided.
--tables with insert statement
create table item_trans (trans_item varchar2(12),trans_qty number,trans_act_qty number)
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE1',40,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE2',20,NULL);
insert into item_trans(TRANS_ITEM,TRANS_QTY,TRANS_ACT_QTY) VALUES ('TREE3',20,NULL);
--i want to set the value of trans_Act_qty as trans_qty
--i create one dummy or test block to keep the select all check box. for that table test script is
CREATE TABLE TEST
(
C VARCHAR2(2000 BYTE),
B NUMBER,
A NUMBER
);
insert into test (C,B,A) values ('A',1,1);
--code written in select all check box which is created on test.block.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
:M_END_YN := :M_END_ALL;
[code].......
--code written in M_END_YN ( actual check boxes where i will uncheck).
IF :M_END_YN = 'N' THEN
:M_END_ALL := 'N';
END IF;
--code written on button to update those values which are checked.

The Scenario is depending upon PROJECT NUMBER the Fields are Populated including FUNDS CHECK FLAG .
But the AUTHORIZAION DATE is a MANDATORY field has to be filled by User
The Requirement is to make AUTHORIZAION DATE as MANDATORY only when the FUNDS CHECK FLAG is *"BLANK "* or *“Y”*
If the FUNDS CHECK FLAG is *“N”* then the AUTHORIZAION DATE to be made OPTIONAL.
