Timestampdiff() function: result in millisecond

Hello,
I'm using the OBIEE timestampdiff() to calculate the difference between two timestamps, before to continue to use this function I want to check if the function can calculate the delay in second and give result like this example:
TIMESTAMPDIFF(SQL_TSI_SECOND, CAST("LOGFILE_VORDEL"."DATE_HOUR" as timestamp),CAST("LOGFILE_VORDEL_S"."DATE_HOUR" as timestamp))=19,23 sec
which mean
19 Second and 23 Millisecond.

try to make it informatica. not sure obiee can support to_date function where you can get date format in milliseconds.

TIMESTAMPDIFF function in combined analysis

Hello,
Has anyone used the timestampdiff function in a combined analysis? I have created a combined analysis with using two subject areas and tried using the timestampdiff function in the results section but its not giving me the right results. I am using timestampdiff(sql_tsi_day, saw_5, saw_3).
Any help is appreciated.
Thanks!
Sonia

I guess you can use TIMESTAMP functions in result columns. The only case where you may hit an error is when one of the columns(say saw_5) is having a null/blank value for the corresponding value in saw_3.

TIMESTAMPDIFF function in OBIEE Answers

Hi experts,
I have a Answers report, where I have included a column and changing the fx formula to find out the time diff ..
TIMESTAMPDIFF(SQL_TSI_DAY, "Bank Transactions - Payor Aging".AccountingDate, "Bank Transactions - Payor Aging".AccountingDate)
here I want the second "Bank Transactions - Payor Aging".AccountingDate to be replaces with any date like as below
TIMESTAMPDIFF(SQL_TSI_DAY, "Bank Transactions - Payor Aging".AccountingDate, '06/02/2010') for June-02-2010.
But, the above date format is working... can any suggest what format I have give here to work.
Thanks in Advance

Hi Madan...
Thanks for the quick reply...
I want to continue by next question on top of the TIMESTAMPDIFF function....
TIMESTAMPDIFF(SQL_TSI_DAY, "Bank Transactions - Payor Aging".AccountingDate, TIMESTAMP '2010-06-02 00:00:00')
how can I pass this part of the value from the Dashboard Prompt. I knew that the dashboard prompt can only be created on the presentation column. I can't put any date column in my datawarehouse datamodel as there is already one. I looking if there any other way of passing the second date value from the dashboard prompt.
Thanks in Advance

Group by Lookup function result

I have a report that uses two datasets.
The first one looks like this. It's the time members have recorded under a particular job title:
ParentId TaskName ObjectiveId MemberId JobTitle TimeSpent Status
3174ED19 TEST 3 42AA79F6 23179C0F NULL 0.00 01
3174ED19 TEST 3 42AA79F6 596CA495 JobTitle1 9.00 01
3174ED19 TEST 1 AEE18C46 23179C0F NULL 0.00 01
3174ED19 TEST 1 AEE18C46 596CA495 JobTitle2 3.00 01
3174ED19 TEST 2 AEE18C46 23179C0F NULL 0.00 01
3174ED19 TEST 2 AEE18C46 596CA495 6.00 01
I need to show the records which have JobTitle == null with a particular Job Title, the current one they have in Active Directory. So I use another dataset from a WCF service:
MemberId Name JobTitle
23179C0F Member1 JobTitle1
Then I use a lookup function to show the correct Job Title:
=IIF(IsNothing(Fields!JobTitle.Value) OR Fields!JobTitle.Value = "",lookup(Fields!MemberId.Value,Fields!MemberId.Value,Fields!JobTitle.Value,"Members"),Fields!JobTitle.Value)
This works ok. The problem is that I need the data to be grouped by several fields, including the Job Title. It seems grouping happens before the lookup function is executed, so instead of grouping the NULL values along with the fields that contains the actual
values, I end up with two groups with the same Job Title, one containing the null values and another with the actual values.
Is there any workaround for this?
Thanks.

Hi EXR88,
Per my understanding that you have add some row group in the report to group the result which include the JobTitle from the table1 and also group by the field which result comes from the lookup funtion, now the issue is the group by the Lookup function result
isn't correct, right?
I have tested on my local envoronment and can't reproduce the issue, please find the details information below to make sure you have done the correct setting:
I tried to create the two tables like below:
Table1:
Have the same recores as you provided above.
Table2:
MemberId    Name      JobTitle
23179C0F   Member1    JobTitle1
596CA495   Member1     NULL
After adding the LookUP function, i got the report like below:
I add two row group base on the JobTitle(JobTitle) and the Lookup functiuon result(Lookupfunctiongroup), the Lookupfunctiongroup row group is the child group of the JobTitle like below, please make sure you have add the expression with the lookupfunction
in the group on:
If i have some misunderstanding, please try to provide the expectted group by result you want to get and also the currectly result you have got.
Any problem, please feel free to ask.

Refering alias of a function result in an sql statement

Dear Sir,
How to refer an alias of a function result in sql statement?
eg.(new_name is the alias)
select myfunction(name) new_name
from mytable
where new_name = '#vincent#';
I can't refer new_name in the above statement coz it gives an error "invalid column name".
But I don't want to put the myfunction(name) again in the where clause which will double the job. So, how should I refer to it?
Please advise.
Thanks.
null

You can not refer to the alias like you are talking. You will have to use myfunction(name) as you have said. Or you can try creating a view with query:
select myfunction(name) new_name
from mytable
and then refer to "new_name".

Function result as an item for another function.

I have a report that has a field A(number) which is the result of a custom function. My next field B needs to sum up all these results i.e. sum of field A grouped by certain field. Another field C needs to divide field B by a calculated number etc.
Because I can't choose function result as an Item, I'd have to recalculate for field B, and again for field C etc, which degrades performance.
Any ideas on how to tackle this problem?

Dear Peter,
Does this amount appear as an amount in your GL and missing in your Asset Accounts, or vice versa.
Please, do check if there are any manual postings performed from FI, not from the depreciation program.
They will disappear from ABST2 when you reverse them from FI.

DB buffer cache vs. SQL query & PL/SQL function result cache

Hi all,
Started preparing for OCA cert. just myself using McGraw Hill's exam guide. Have a question about memory structures.
Actually, DB buffer cache is used to copy e.g. SELECT queries result data blocks, that can be reused by another session (server process).
There is also additional otion - SQL query & PL/SQL function result cache (from 11g), where also stored the results of such queries.
Do they do the same thing or nevertheless there is some difference, different purpose?
thanks in advance...

There is also additional otion - SQL query & PL/SQL function result cache (from 11g), where also stored the results of such queries.Result cache located in shared pool.So it is one component of shared pool.When server process execute query(and if you configured result cache) then result will store in shared pool.Then next execution time run time mechanism will detect and consider using result cache without executing this query(if data was not changed this is happen detection time)
Do they do the same thing or nevertheless there is some difference, different purpose?.Buffer cache and result cache are different things and purpose also,but result cache introduced to improve response time of query in 11g(but such mechanism also implemented in 10g subquery execution,in complex query).In buffer cache holds data blocks but not such results.

OBIEE timestampdiff function syntax error

Hi all,
I am getting an error while applying timestampdiff function .help me to sort it out.
TIMESTAMPDIFF(SQL_TSI_DAY,"- Sanction and Disbursment"."Value Date" , VALUEOF(NQ_SESSION.VAR_CAL_CURR_DATE))
error details
Formula syntax is invalid.
[nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 22025] Function TimestampDiff is called with an incompatible type.Please have your System Administrator look at the log for more details on this error. (HY000)
SQL Issued: SELECT TIMESTAMPDIFF(SQL_TSI_DAY,"- Sanction and Disbursment"."Value Date" , VALUEOF(NQ_SESSION.VAR_CAL_CURR_DATE)) FROM "SIDBI Master"

Aswin,
Syntax looks to be fine but before applying it here can you check if both these 2 parameters returns date in same format:
"- Sanction and Disbursment"."Value Date" = 08/21/2011 (No Timestamp)
VALUEOF(NQ_SESSION.VAR_CAL_CURR_DATE) = 08/21/2011 (No Timestamp)
Both shud have same format.
Also, try this for verification
TIMESTAMPDIFF(SQL_TSI_DAY,"- Sanction and Disbursment"."Value Date" , CURRENT_DATE)
Hope this helps

Populating a collection with function results

I am calculating some statistics and need to use a collection to store the results of several function so they can be used in a procedure. Example:
PROCEDURE PRODUCTIVITY_INSERT(p_first_of_month IN DATE)
AS
BEGIN
vc_FirstofMonth := p_first_of_month;
FOR i IN 1..3 loop
EXECUTE IMMEDIATE 'INSERT INTO RFC_BUS'||days(i)||'PRODUCTIVITY(ROUTE,PPPH)
SELECT a.route, ((sr05 / sy05)/'||counts(i)||') AS "RATIO"
FROM (SELECT route,
SUM (DECODE (TO_CHAR (pick, "MM-YYYY"),
to_char(vc_FirstofMonth, "MM-YYYY"), platform_hours, null)) AS sy05
FROM bus_platformhours
WHERE day_type ='||days(i)||' and platform_hours > 0
GROUP BY route) a,
(SELECT route,
SUM (DECODE (TO_CHAR (service_date, "mm-yyyy"),
to_char(vc_FirstofMonth, "MM-YYYY"), rides, null)) AS sr05
FROM bush_daily_rides
WHERE day_type = '||days(i)||
'GROUP BY route) b
WHERE a.route = b.route
ORDER BY a.route
VALUES(
p_route,
p_ratio
) USING days(i), counts(i)';
end loop;
Can I use collections to hold the function results (say three function out variables) while they are being looped through in the procedure? If I can do that I am presuming I use the functions name in the collection such as:
TYPE dayoneList IS TABLE OF NUMBER;
dayone dayoneList := dayoneList(wkdaysminusone(), sadaysminusone(), sudaysminusone());
thanks for any help you can give me.

Do you mean to use the functions as the elements of collection constructor ?
It's possible:
SQL> create function get_one return number is begin return 1; end;
2 /
Function created.
SQL> create function get_two return number is begin return 2; end;
2 /
Function created.
SQL> declare
2   type arr is table of number;
3   arr1 arr := arr(get_one(), get_two());
4 begin
5   for i in 1..arr1.count loop
6    dbms_output.put_line(arr1(i));

Get the Stored Function Results

If there is DML in my Stored Function ,how to Using View Objects to Select Stored Function Results?

Using ASSOCIATED on a function result

I'm having trouble using the ASSOCIATED intrinsic with the result of a function. It appears to work in Studio 12 but in 12.2 I get a segfault. The problem happens when the result of a function is set to null. It appears that the function result pointer somehow becomes undefined (but I'm not sure). For example the following sample program gives a segfault in Studio 12.2:
double precision, pointer :: input=>null()
if (associated(getY(input)) then
print*, "associated"
else
print*, "not associated"
endif
contains
function getY (y) result (yResult)
double precision, pointer :: y
double precision, pointer :: yResult
yResult => null()
if (associated(y)) then
yResult=>y
endif
end function getY
If however if first associate a new local variable with the function result (x=>getY(input)) I don't get a segfault when calling associated(x). Any ideas on why this happens or if I'm doing something wrong?

I apologize for taking so long to respond.
After modifying your code slightly so that it would compile, I was able to reproduce the problem using the Oracle Solaris Studio 12.2 release. When I compile the program with the beta compiler for release 12.3, it works correctly. The output is
not associated
I hope the problem has been resolved.

You'll get this error if the difference between the start and end date is greater that about 68 years due to the "second" DATEDIFF specification. Perhaps the dates are greater than the expected range due to a data quality issue.
Taking the advice from the error message, you could use minutes instead of seconds like the example below the version below. This could still result in the error of the difference is greater than a couple of hundred years, though. You might consider
validating the dates and returning NULL if outside expected limits.

CallableStatement, how to get function result ?

Hello all,
I know that this issue more relevant to JDBC, but it seems that their forum is more "sleepy" than that one therefor i trying my luck here with you...
I've a pl/sql function which get 2 int arguments, and return float result
I use CallableStatement in order to execute pl/sql function.
with CallableStatement.setInt i transfer argument to the function,
but i dont know how to "catch" function result (as i said earlier, function results is float)
any help here...
Thanks

that's exactly what i did, but my teacher assistant told me that it's wrong, because CallableStatement uses for stored Procedures, but I have here a function (because it returns a value...) therefor i need to use PrepareStatment/Statement...Third person accounts are always hard to judge, but what you are claiming is wrong (whether the TA said it or not.)
First a prepared statement can in fact be used to run either a proc or function. So can statement for that matter.
However callable statement is provided as a convenience to run procs and functions.
There can however be reasons why a driver doesn't allow that - I have used a driver that didn't support callable statements at all (procs or functions.)
That said the the format I gave you is specifically modeled for functions.

TimeStampDiff function ROUNDing the result. How can we avoid this?

I want to get the results in the actual decimal point and not the whole no. Is there a way that I can enable the TIMESTAMPDIFF not to ROUND by default.
Any answers will be helpful.
Thanks,

When you specify in the interval in the first argument of TIMESTAMPDIFF you are implicitly telling OBIEE the level of precision that you want. For SQL_TSI_YEAR you are going to get integer values of whole years. if yo uneed to get more granular than that you need to use SQL_TSI_MONTH or WEEK.
Also note, than when performing mathematical operations like divide an multiply, all elements of the calculation need to be a data type that can represent decimal values, or the result of the entire calc will always get converted to an integer.
