Hi,
I have testcycl table which holds the results of tests for each testid and the status with execution date and time as below:
TESTCYCL
TESTID STATUS TEST_EXEC_DATE TEST_EXEC_TIME
1234 Passed
01/12/2014 00:00:00 9:00
1234 Failed
01/14/2014 00:00:00 11:00

Please help me abt this. Thanks in advance

Please try the following.
;with TESTCYCL as
SELECT 1234 AS TESTID, 'Passed' AS [STATUS], CONVERT(DATE,'01/12/2014 00:00:00') AS TEST_EXEC_DATE , CONVERT(TIME,'9:00') AS TEST_EXEC_TIME
union all
SELECT 1234 AS TESTID, 'Failed' AS [STATUS], CONVERT(DATE,'01/14/2014 00:00:00') AS TEST_EXEC_DATE , CONVERT(TIME,'11:00') AS TEST_EXEC_TIME
union all
SELECT 1234 AS TESTID, 'Passed' AS [STATUS], CONVERT(DATE,'01/14/2014 00:00:00') AS TEST_EXEC_DATE , CONVERT(TIME,'22:00') AS TEST_EXEC_TIME

How to find out the latest Record in per_all_people_f and per_all_assignme

Hi ,
How to find out the latest Record in per_all_people_f and per_all_assignments_f
Requirement : Need to find out the latest record in per_all_people_f and per_all_assignments_f to update the attribute column with pre defined value . Its not possible to track only with person_id / assignment_id and effective end date
SELECT pp_id
FROM (SELECT app.person_id pp_id,
asf.*
FROM apps.per_all_people_f app,
apps.per_all_assignments_f asf
WHERE --app.person_id=123568 and
asf.person_id = app.person_id AND
app.effective_end_date = to_date('31-dec-4712') AND
asf.effective_end_date = to_date('31-dec-4712')
GROUP BY app.person_id)
HAVING COUNT(pp_id) > 1
GROUP BY pp_id
This query also returns more than 1 value for person_id .
It would be great if you put comment on this .. Thanks in advance ,

Formula to get the latest record

Hi,
I looking to have only the last record logged displayed on my report, can any one help me with the formula ?
Sorry,
Actually to be more precise I'm looking to the latest record for each equipment (where there are many records for the equipment during the day).
Many thanks,
Andreia

Hi,
You could use a SQL Expression field. The following example uses the Northwind database (SQL Server) as an example.
Type the following query in the SQL Expression editor
(SELECT MAX("Orders"."OrderDate")
FROM Orders
WHERE CustomerID = Customers.CustomerID)
Then create a record selection formula:
{Orders.OrderDate} = {%datum}
{%datum} is the sql expression
When you run the report, you will see only the last order for each customer

Select the one record with the latest record

I have the following table called tblSales:
SKU   TransDate   Color
===   ====== ====
123   1/1/2015    Red
123   1/2/2015    Red
123   1/5/2015    Red
123   1/1/2015    White
123   1/2/2015    White
123   1/3/2015    White
123   1/1/2015    Blue
123   1/2/2015    Blue
123   1/5/2015    Blue
I need to create a query along the lines "SELECT the latest record FROM tblSales WHERE Color = 'White''
In this example, the record dated 1/3/2015 would be the result. I know that MAX(TransDate) is used here, but not sure how.
Thanks.
Ken

Karl,
I had already tried that. It returns all 3 records having SKU = 123 and Color = White.
Worst case scenario is I can always search for White 123s using a query with TransDate DESC and then get the first record. I was just hoping for something a bit more elegant.
Thanks for your help though.

Fetching the latest drawing No. after changing Sampling Drawing Procedure

Hi QM Masters,
I have 1 Report in that I fetch Drawing No. against Inspection Lot.
When I create a Inspection Lot at that time Drawing No. will generated in the system. Sampling Drawing procedure is assigned to the Lot. But the problem is that When I change the sampling procedure New Drawing No. is generated against the same lot.
Both Drawing No. are updated in QPRS table against the same lot. That's why It is difficult to fetch the latest Drawing no.
How I fetch the latest drawing no. after changing the SDP?
Gives me the Expert logic to fetch the data.

Hi can you check the fields ENTDATUM and ENTZEIT for sample drawing date and time or this date is different for you in the same table QPRS

How to get only the latest record in a folder

Hi all,
We have an OA SIT that is not a "standard" SIT in that it does not have the traditional Begin and End date. It only has an Effective date. Is there some way I can filter this table to only give me the latest record in the series? I know how to do this in SQL, but don't see how it would be possible in the EUL.
We're trying to avoid creating database views, but at this point, I'm thinking it may be the easiest way to address this. Any other suggestions?
Thanks in advance,
Jewell

Jewell.
Of course I'm not going to mention that I have no idea what a 'standard' SIT is compared to your basic 'non-standard' SIT ... and I have to watch my spelling of such ... but however ...
As you're most likely aware, in SQL you would get all the 'standard' SIT records first by going through the table. Then you'd go back through them all and find the most recent one.
Because of this 2 table pass, I agree that just putting the SQL code in a custom folder (as you're not using views) would make the most sense.

Problem in fetching the latest updated record.

Hello ,
I have a program in which i am creating a BDC session and submit the same in program rsbdcsub, now the problem is that i need to capture the Field Qstate from the table APQI, its not updated instantaneously, so i am not able to get the latest value of QSTATE from updated APQI table,
I have used commit work, commit work and wait , SET UPDATE TASK LOCAL, nothing is working, only if i put wait up to '1.5' seconds before fetching the value from table APQI i get the updated Qstate, but this will create a performance issue so please suggest.
Can any one please help me resolve this problem.
Regards,
Abhinav

it's quite normal that status is updated after the job is modified
and you cannot know beforehand how much time it will take to do it (even the start time is not sure because it could be delayed !)
you could select the value until it is one of a list that you expect (for example, finished or cancelled)

Need to fetch the last record/row from a table

Hi,
I have a requirement like fetching the closing balance of the last record of the table and inserting the same into the opening balance of the immediatetly created next record.
In simple words, I need to fetch a value from the last row of the record.
For example, I use the below query,
select rownum, empno, ename from emp
where rownum = (select count(rownum) from emp);
But, the above query does not return any of the record.
Hence, need help on this.
Regards,

Rows in a table are inherently unordered. In order to introduce the concept of "first" and "last", you would need to specify how to order the rows which would require that there was one or more columns in the table that you could order by in order to determine the "last" record.
In your closing balance example, if we assume that there is something like a BALANCE_DATE column,
SELECT account_number, balance_amount, balance_date
FROM (
    SELECT account_number,
           balance_amount,
           balance_date,
           rank() over (partition by account_number order by balance_date desc) rnk
      FROM table_of_balances )
WHERE rnk = 1Justin

Cursor not fetching the latest value in the loop.

Hi!
I'm facing a peculear problem. I've a procedure which will check the total number of records in a loop. It will fetch that value. If that value mathced with certain condition then the outer loop execution need to stop. Here is my script -
<<Outer Loop Script>>
declare
j number(5);
begin
j := 1;
dbms_output.enable(100000);
while j <> 3 and j <=3
loop
sel_pri(3,j);
dbms_output.put_line('J is : '||j);
end loop;
dbms_output.put_line('Executes.....');
exception
when others then
 dbms_output.put_line(sqlerrm);
end;
-- Procedure Script --
create or replace procedure sel_pri(x in number,y out number)
is
pragma autonomous_transaction;
begin
 select count(a.flg) cnt
 into y
 from (
 select flg
 from t_priority
 where flg <= x
 and flg < 4
 union
 select flg
 from t_priority
 where flg > x
 and flg < 4
 ) a;
--commit;
end; Now, the problem is -
Suppose i've two records are there in t_priority table. So, when i run my anonymous pl/sql block it won't satisfy the condition - as a result the loop will iterate untill the condition satisfiy. Now, if i insert data from a different session and commit the value in table t_priority which have only one field named flg and if count is 3. Then the process of the while loop should be stopped. But, it that is not happening. Infact it is fetching the old value. Why is it so?
Thanks in advance for your reply.
Regards.
Satyaki De.

But you see the data as they were at the moment (exactly SCN - System Change Number) of the query issue dispite they have been changed by another transaction after the cursor has been open. Hope I'm clear now.

How to fetch the data records in summary format based on previous day

drop table T1;
create table T1(Class, Fees_Collected, Submit_Date) as select
'MBA', 100000, '7/30/2012' from dual union all select
'Btech', 20000, '7/10/2012' from DUAL union all select
'MBA', 45000, '8/1/2012' from dual union all select
'Btech', 55550, '7/31/2012' from DUAL union all select
'BBA', 250660, '7/30/2012' from dual union all select
'MBBS', 44556000, '7/31/2012' from DUAL union all select
'BDS', 420050, '8/1/2012' from DUAL union all select
'BBA', 30450, '7/30/2012' from DUAL union all select
'MBBS', 120450, '7/31/2012' from DUAL union all select
'BDS', 45950, '7/30/2012' from DUAL union all select
'MBA', 252450, '8/1/2012' from DUAL;My requirment is to fetch the records based on summary format to display the data with following columns -
Class |Prev Day Traded Value |Prev Day % of Total |Prev Day % MBA
Note - Previous Day definiton (Buisness Day) = calendar days - (weekends + US Holidays)
Kindly help me, as i want to keep it customized so that without specifying the hard coded dates ( Previous Day) it runs through and provide me the resultset....
All of your help and time is highly appericated.

You mean business days I guess ?
I use a function (I had to write it myself) <tt> next_business_day(p_start_date in date,p_days_count in number) return date </tt>
where I loop forward/backward from p_start_date according to the sign of p_days_count the required number of steps skipping weekends and holidays as the absolute value of p_days_count is mostly under 30 for the rest (at least around here) Oracle's <tt> add_months </tt> gets it done.

Year till date: <tt> your_date between trunc(sysdate,'year') and sysdate </tt> is it ? http://en.wikipedia.org/wiki/Year-to-date ?

NOT TESTED!
function next_business_date(p_start_date in date,p_count_days in number) return date is
steps number := abs(p_count_days);
retval date := p_start_date;
begin
if p_start_date is null or p_count_days is null then
 return to_date(null);
end if;
while steps > 0
loop
/* skipping weekends and (yet to be implemented) holidays */
 while to_char(retval,'dy') in ('sat','sun') /* or is_holiday(retval) */
 loop
 retval = retval + sign(p_count_days);
 end loop;
/* retval contains a business day now */
 retval = retval + sign(p_count_days);
 step := step - 1;
end_loop
return retval;
end;

How can I fetch the first row into the cache?
I checked the documentation & it says i should call the required API to put the record into the cache & then retry the operation, so what is this API? what should i do?
Thanks alot for any help
best regards

I'd recommend processing the records inside a custom method on your application module. This is a best practice whever you can do it, and it makes your application easier to maintain and test.
I'd also recommend using Immediate Mode instead of Batch Mode. Please see this article on the subject:

Getting the Latest Record.

Consider 2 tables TestCases and TestRun
a test Case can have multiple test runs ie. TestCaseId from the Test Case Table will map into N number of Rows in TestRuns table.
I want to do a count of all the test runs which are pass, but as there are multiple entries in TestRun against the testcaseid all the test runs are counted.
what we require is to add up Results against the latest test run.
*The TestRun table has a Run Date field.

Play around with the RANK function:
SELECT RANK("D0 Time"."T00 Calendar Date") saw_0, "D0 Time"."T00 Calendar Date" saw_1, "F2 Units"."2-01 Billed Qty (Sum All)" saw_2 FROM "Sample Sales" WHERE RANK("D0 Time"."T00 Calendar Date") = 1 ORDER BY saw_1 DESC
