SQL & PL/SQL :: Summation Of Time Field?
Sep 18, 2012
I have a table with 2 columns storing information on start time and end time and i want to find out the time difference between them and i want a total for this , how can i get the summation on this calculated duration field.
create table ot_job (jh_no number,jh_start_01 date ,jh_end_dt date,jh_st_time varchar2(30),jh_end_time varchar2(30));
insert into ot_job values (1,'01-SEP-2012','01-SEP-2012','11:30','11:50');
insert into ot_job values (2,'01-SEP-2012','01-SEP-2012','08:15','14:00');
insrt into ot_job values (3,'01-SEP-2012','02-SEP-2012','23:00','23:00');
SQL> SELECT jh_no, jh_end_time, jh_st_time,
2 (TRUNC ( ( TO_DATE (SUBSTR (jh_end_time, 1, 5), 'HH24:MI')
3 - TO_DATE (SUBSTR (jh_st_time, 1, 5), 'HH24:MI')
4 )* 24 )
[code]...

i am facing a very challenging situation and i am not able to write a query. consider the following data
SELECT 16 num, 17 num2 , 3 num3, 22 num4, 10 num5 FROM dual
UNION ALL
SELECT 9 num, 15 num2 , 21 num3, 2 num4, 24 num5 FROM dual
UNION ALL
[Code]....
[URL]..... i am trying to write a query that given two values it will give you summation of the values within a particular bucket. for example, please see attachments, highlight in yellow.
if value 15 and 19 is given, i want to find the total sum of all values yellow (capture.jpg).
if value 8 and 21 is given, i want to find the total sum of all values in yellow (capture2.jpg)
if value 8 and 14 is given, i want to find the total sum all of values in yellow (capture3.jpg)
basically, when given two values, i draw a square or rectangle from starting number(first number) to end number and sum up all the values
write a query for such scenario. i heard it can be done with analytic functions but dont know how to use it. im using oracle 10g and 11g

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 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 varchar field and user will enter the time in that field as per the format HH:MI HOURS:MINUTES.Actually there is no control on this field and user is making mistakes like instead of HH:MI he is entering HH;MI.

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
Example
SELECT Sector.Date, Sector.RNC, Sector.Site, Sector.Cell,Sector.PSC
FROM Sector
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

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.
BEGIN
GO_BLOCK('item_trans');
FIRST_RECORD;
LOOP
IF :M_END_YN = 'Y' THEN
[code]......

I am New to Apex. Im using Apex Version 4.2.
I have a tab named APPROPRIATIONS it has 10 fields. Among which is PROJECT NUMBER, AUTHORIZAION DATE (CALENDER TYPE POPUP), And FUNDS CHECK FLAG.
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.

When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data:
<?xml version="1.0"?>
<RECORD>
<REGTIMESTAMP>20120601130010</REGTIMESTAMP>
</RECORD>
PL/SQL Extract:
CURSOR c_xml_record
IS
SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP,
FROM t_xml_data x,

I have a table which stores apointment start times and appointment end times. For the sake of this thread I will call them appt.start_time and appt.end_time. I then have a check in time and a check out time for the customer. The only thing is they ONLY way to distinguish between a check in time and a check out time is which one has the earlier time and which one has the later time. Obviously the earlier time will be the check and the later time will be the check out.
This is fine, however sometimes they may forget to check a person in or out and I need to determine whether the time should be insert into the check_in column or the check_out column. To do this I was thinking of comparing the time with the appointment start and end time and if it was closer to the appointment start time put it into the check_in column and if its closer to the appointment end time put it into the check_out column. But I was wondering how I would go about doing this.
The time I will want to compare against the appointment start and end time I will store in a variable called v_time and have this as part of my query, im just unsure of what way to write the query so as to check if the time is closer to the start or end time.

. I have this query:
select asl1.agentsessionid, asl1.endtime, asl2.starttime, 127 as agentstatus
from
(
select asl1.agentsessionid as sessionid1, min(asl2.agentsessionid) as sessionid2
from cti.agentsessionlog asl1
[code]...
As you can see from my where statement I want to compare the endtime with the startime. This query returns zero results. Is there a way to write the where statement different so I can have results?

I have an application in which time is show as . But, in the table in Oracle it is showing as 13:00. The application is taking the time from OS. OS time is 18:30 IST. Time in SYSDATE is also showing as 18:30. DBTIMEZONE is '+5:30'. what is the problem in Database and how that can be rectified to show the time as same as OS time.

We have a Oracle 10g database with RAC and Dataguard. When we look at the AWR report, the wait time shown by Oracle for this database is very high.
Service Time : 15.36%
Wait Time : 84.64%
This would imply Oracle is waiting for resources 85% of the time and only processing SQL queries during 15% of its non-idle time. However when we check the OS (RHEL), the iowait is only about 10% and the CPU is 80% idle. This means that that processing horsepower is available.
As such, the results between the OS and Oracle database (AWR report) seems contradictory. OS says we have CPU/IO capacity, however Oracle says we don't.

I have bills and payments for a customer, a customer may make many payments against 1 bill. I want to figure out the time taken from bill issue date to the time the balance of the customer falls to less then 10% of the most recent bill.I have managed to compute the running balance for the customer
So something like:
DATE AMT BILL_AMT BILL_DATE BALANCE
6-Oct-11 38533 38533 6-Oct-11 38533
20-Sep-12 -6000 0
6-Dec-11 78552 78552 6-Dec-11 78552
[code]....
But I need to know when the running balance falls beneath 10% of the previous bill.
I thought a way to do this would be to keep the same bill amount in the BILL_AMT column until the BILL_AMT is not null which means that a new bill has been issued.
I can't use LAG because the number of records I am going back by increases by 1 for each row where the BILL_AMT is null.I also can't use a running total because I don't want the total for all of the records for the customer, just the total (i.e. the bill amount and all intervening nulls (which would be the bill amount)) since the last bill?
i.e. how can I keep the same value in a field as long as the values in that field are null and then adopt a new value when there is a non-null value?

Trying my best to follow the posting guidelines.
There are two tables.
orderheader and orderdetails. orderheader is a master table and orderdetails is a detail table. So for every one record in orderheader table, there are many records in orderdetails table. I want to update a field in orderdetails table from a orderheader table using inner join.
update orderdetails
set orderdetails.conversion_dt =
(select orderheader.conversion_dt
from orderheader, orderdetails
where orderheader.number= orderdetails.number )
I get the following error:
Error report: SQL Error: ORA-01427: single-row subquery returns more than one row 01427. 00000 - "single-row subquery returns more than one row"
