Using FIRST and LAST

Hi everyone,
I'm extracing some Sales Volumes per Account out of our database.
I need to calculate the total Volume per Account, except the FIRST volume in the set...if I use the FIRST() SQL function in the column formula though, I get an error. Is it possible to use it in OBIEE?
Regards,
Alberto

Ciao Vino,
thanks a lot for your suggestion...unfortunately I think the FIRST function is not supported on our server...look @ the error I get:
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 16001] ODBC error state: 37000 code: 8180 message: [Microsoft][SQL Server Native Client 10.0][SQL Server]Statement(s) could not be prepared.. [nQSError: 16001] ODBC error state: 37000 code: 195 message: [Microsoft][SQL Server Native Client 10.0][SQL Server]'FIRST' is not a recognized built-in function name.. [nQSError: 16002] Cannot obtain number of columns for the query result. (HY000)
Do you confirm?

Finding first and last members of a group set

Is there any example how to use 'first' and 'last' functions in an sql query ?
I have tried to execute a query like this on the scott.emp table :
select deptno,min(sal),max(sal),first(sal) from emp group by deptno;
but I always get this message:

Syarif,
The FIRST and LAST functions, which became available with 9i, are used to find the first or last member of a ranked set. I'm not sure exactly what you are trying to do, but I can show you a query that should work (I don't have 9i handy at the moment). This query should give you the departments with the highest (first) and lowest (last) aggregate salaries:
select deptno,
min(deptno)
keep (dense_rank first order by sum(sal) desc) highest_sal,
min(deptno)
keep (dense_rank last order by sum(sal) desc) lowest_sal
from emp
group by deptno

Edited by: davide gislon on 08-Jan-2009 07:19Your query does nothing you say it does. TO_DATE('&year','YYYY') returns first day of the current month for year &year. And the only reason it returns January 1, &year is that we are currently in January:
SQL> select TO_DATE('&year','YYYY') from dual

How can I display the first and last name using a paramater as employee ID?

Hi SAP,
I have a parameter that is called {? Employee ID}. What I want to do is display the first and last name based on the employee ID value entered in {? Employee ID} in the page header of the report. Right now, when I put the following formula in the page header only some pages get the right result while other pages dont....
if table.employeeid = {? Employee ID} then
table.firstname" "table.lastname
It appears as though if the first record in the details section on the beginning of each page happens to be the employee under {? Employee ID} then it prints it correctly, if it isn't I get a null value in the page header.
Anyone have any ideas?
Z

Hi Try this,
Whileprintingrecords;
if ={?EmpID} then
Also check the option "Default values for null" in the formula editor.

Vinay

Can only see first and last frame of clip in the timeline HELP PLEASE

Hi, my first time and I did look for an answer, but can't find one. I have premiere elements 4 and I am trying out ver. 9. In ver. 4 the clips in the timelin shows all the frames, but in ver. 9 it only shows the first and last frame of the clips. Is there any way to make all the frames show. By "all the frames", I mean the clips fill with frames.I liked to see all the frames in the timeline, it is easier for me to select and trim the bits out.
My specs are Core 2 Duo 6750, Nvidia 8600GTS, 4G Ram, Vista Home Premium. 3 HDD 3TB.
Thank you for answering

As for the GUI, PrE had one more like PrPro (the early versions), up through PrE 3. With PrE 4, they streamlined the GUI (and some of the operation), and went with the "dark look." PrPro went in that direction starting with CS3, and now, the two programs' GUI looks more alike - darker. Personally, I like PrPro 2.0's brighter GUI. Now, one can alter the brightness, but the contrast can work against doing much of that - give me the lighter GUI....
The look of PrE 4 thru PrE 9 is very similar, though things have moved about some. Still the look is similar. Same for PrPro CS 3 through CS 5.5.
As for the trial, things have changed in PrPro, as of CS 5.5. Once, the PrPro trial was very crippled, but had no watermark. No more. No crippling, and still no watermark. The trial for PrE is far less crippled, but does have the watermark. We do not know what changes might be coming with the trial of PrE10. We will just have to wait and see. One great option that Adobe offers is the 30-day, money-back guarantee. If you buy Premiere (either flavor), and use it for 29 days, but do not like it, then you return it for your money back. This is the full-paid version (both flavors) with nothing crippled, and no watermark. Not that many companies make such an offer. Basically, on can use the trial for 30 days, to see some of the powers of the program, and then buy it, and try it fully for another 29 days. If not completely satisfied, they get their money back - essentially a 59 day trial.
Were I doing AVCHD, I would definitely look at buying PrE 9, and giving it a 29 day shakedown. The only caveat is that AVCHD requires a lot of computer "horsepower," and not all computers (especially if more than a year, or so old) are up to that task. I find it amazing that a consumer format, like AVCHD, requires more computer power to process, than most professional formats, until one gets up to, say RED 2K/4K. However, that is the nature of the H.264 CODEC, and by that, I mean all H.264, not just the AVCHD version.
Good luck and happy editing,

How to find first and last day of last month?.

Hello,
I am using Crystal Report XI.
Reports will be generated on first of every month for
previous month. I want to find start and end date of previous month
dynamic.
For august, Start date is July 1st and End date July 31st.
For September, start date is Aug 1st and Aug 31st.
How can i get first of previous month as start date and last
day of the previous month as end date?.
Same kind of thing I want to do for future report ..find next
month start date and end date.
Thanks

Adomacro,
you could do a function, like this
<cffunction name="getReportdates" returntype="struct"
hint="Given an arbitrary month and year, the function returns a
structure containing the first and last day of the previous
month">

<cfargument name="mnth" type="string" required="No"
default="#monthAsString(month(now()))#">
<cfargument name="yr" type="numeric" required="No"
default="#year(now())#">
<cfset firstDayOfGivenMonth = parseDateTime("1 " &
arguments.mnth & " #arguments.yr#")>
<cfset lastDayOfPreviousMonth =
dateAdd("d",-1,firstDayOfGivenMonth)>
<cfset numberOfDaysOfPreviousMonth =
daysInMonth(lastDayOfPreviousMonth)>
<cfset firstDayOfPreviousMonth =
dateAdd("d",-#numberOfDaysOfPreviousMonth#,firstDayOfGivenMonth)>
<cfset reportDates = structNew()>
<cfset reportDates.firstDayOfPreviousMonth =
firstDayOfPreviousMonth>
<cfset reportDates.lastDayOfPreviousMonth =
lastDayOfPreviousMonth>
<cfreturn reportDates>
</cffunction>


Given month: March
2004 
begin date:
<cfoutput>#dateFormat(getReportdates('March',2004).firstDayOfPreviousMonth,"d
mmm yyyy")#</cfoutput> 
end date:
<cfoutput>#dateFormat(getReportdates('March',2004).lastDayOfPreviousMonth,"d
mmm yyyy")#</cfoutput> 


Given month: August
2007 
begin date:
<cfoutput>#dateFormat(getReportdates('August',2007).firstDayOfPreviousMonth,"d
mmm yyyy")#</cfoutput> 
end date:
<cfoutput>#dateFormat(getReportdates('August',2007).lastDayOfPreviousMonth,"d

Get First and last day of Month..

Hi Friends,
I am trying to fetch First and Last day of a month and would like to implement that in the following code:
SELECT COALESCE(Date_A, Date_B, Date_C)
FROM dual
Here Date A and B are in Format of MM DD YYYY (March 14, 2008)
and Date C is like MM YYYY (March 2008)
How can I get the Date_C as March 1, 2008 OR March 31, 2008 format if Date A and B are NULL ?
Thanks!

Hi,
In my earlier message, I thought that you were starting with strings like '03 12 2009' and that you wanted to display them as 'March 12 2009'. If what you have is just the reverse, then just reverse the format strings in my first message. Add a comma, if you want one, in the appropriate format string.
I believe this is what you want:
COALESCE ( TO_CHAR ( TO_DATE ( Date_A, 'fmMonth DD YYYY'), 'MM DD YYYY')
         , TO_CHAR ( TO_DATE ( Date_B, 'fmMonth DD YYYY'), 'MM DD YYYY')
         , TO_CHAR ( TO_DATE ( Date_C, 'fmMonth YYYY'),    'MM DD YYYY')
         )Notice how, on the 3rd line, TO_DATE is called without DD in the format string:
TO_DATE ( Date_C, 'fmMonth YYYY')When you do this, the day defaults to the 1st of the month, so this is all you have to do to convert the VARCHAR2 'March 2009' to the DATE 01-Mar-2009.
If you want the last day of the month, not the first, when Date_C is chosen, then use LAST_DAY:
COALESCE ( TO_CHAR ( TO_DATE ( Date_A, 'fmMonth DD YYYY'), 'MM DD YYYY')
         , TO_CHAR ( TO_DATE ( Date_B, 'fmMonth DD YYYY'), 'MM DD YYYY')
         , TO_CHAR ( LAST_DAY ( TO_DATE ( Date_C
                                          , 'fmMonth YYYY'
             , 'MM DD YYYY'
         )

Query : first and last 25 records of a table

Hi @ll,
i am going to write a query for a report. Therefor i need the first and last 25 records of a table. Does anyone got an idea for a solution ? I was trying to achieve this by using a WHERE clause. Here is a part of the query :
SELECT
TOP 10 T1.[ItemCode], DATEPART(mm, T1.[DocDate]) [.....]
FROM FROM INV1 T1
Where T1.[DocDate] >= Cast('2009 [......] AND
T1.ItemCode = (
SELECT TOP 10 T40.[ItemCode]
FROM DBO.OINM
WHERE Where T40.[DocDate] >= Cast('2009-04-01 00:00:00' AS datetime)
AND T40.[DocDate] <= Cast('2009-04-30 00:00:00' AS datetime)
GROUP BY T1.[ItemCode], DATEPART(mm, T40.[DocDate])
ORDER BY SUM(T1.[TotalSumSy]) ASC)
The where part i would use twice, once for ascending the other one for descending. But it does not work.
Any ideas ?
Regards Steffen

Hi,
Union was the keyword, that i was searching for. It is a nice way, but not practible.
We are using coresuite for generating reports, and there were a nice possibility to connect diffrent queries.
Thanks for your suggestion.

Is it possible to select multiple layers by selecting first and last layers?

I frequently get Illustrator files in that have individual objects such as paths on individual layers that could be grouped to make the layers more concise. I find that I have to shift click each individual layer to select it to eventually group it. At times, I have 25 or so layers that I need to select. Is there a way to select the first and last layer in the layers palette, and have Illustrator select all layers in between?

Katrina,
And I guess it's the way I work. 1) I routinely select objects by selecting them from the layers palette, and not the canvas, so that I can't accidentally move an object that is the clients artwork. I prefer to work this way, as I consider it "safer". (I lock layers I'm not using) I routinely run into artists work that for instance, converted fonts to outline, and now each compound layer that is an individual letter is an object on it's own layer. 2) I need things grouped together and titled so that if I need to come back to this file and quickly fix something on press, I can tell what layer holds what object.
3) Therefore, I frequently need to select objects in a two mile long (slight exaggeration ) list of layers/sublayers and group them, retaining them in their same layers in the event an effect has been applied at the top hiearchy of that layer.
It would be great if a key, or combination of keys, would allow me to select the top object, scroll down and select the last object, and have Illustrator select all between those two.
If you create and use selections as suggested in post #12, you do have to select individual objects when they share layers with other objects (but you can select whole layers as well) in exactly the way you are used to (1), but you only have to do it once instead of having to repeat it (3), and you have them collected with a title so you can find them again (2).
At least it is part of the way.

Thank you for useful post , How to change Culturinfo as a Turkish Month name ?
your's code is work if I use English month name But it was get error when use the turkish month name
If you are running your application on a Turkish Windows you could use the System.Globalization.CultureInfo.CurrentCulture:
int month = DateTime.ParseExact(monthName, "MMMM", System.Globalization.CultureInfo.CurrentCulture).Month;
Or you could use create an explicit culture object like this:
System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("tr-TR");
int month = DateTime.ParseExact(monthName, "MMMM", ci).Month;

Jbo:DataScroller - how to ensure 'First' and 'Last' action links appear

I'm working in JDeveloper 10.1.3.5.0.
I'd like to know if there's a way to ensure that the action links 'First' and 'Last' will appear, in addition to the 'Next' and 'Previous' ones (that is, assuming we're not already at the first or last range position).
It seems as if the thing that determines whether or not they appear is the number of total range positions. I can't be certain, but it seems like the magic number is 1000. If there are fewer, then 'First' and 'Last' will appear, and if there are more, then they will not. It'd be great to be able to have control of this, though. Is it possible?
Thanks

Encore is being phased out? I would be surprised if Adobe did not offer some kind of DVD authoring solution in it's place. I have not heard about this yet myself.
I have a menu size issue because, despite my reported file size being under 4.7G, Encore continues to report a menu size problem. Of course it doesn't say which menu or by how much it is exceeded. When I build it to DVD it waits several hours before reporting that there is a space issue. See below.
There is a file called woodstock-1.mp4. I can find no use of this clip at this point and it's not part of a timeline, yet Encore won't let it be deleted. Encore reports it's still in use. Surely there should be some way to track down any dependencies quickly.

Displaying current user's first and last name on a report.

I would like to dispay the current user's name on a report. I've tried using User() and NQ_SESSION current user .
These two options display the User ID (i.e. User name is Jon Smith. there ID is COMP/JSMITH.
Using the two methods above the ID (COMP/JSMITH) is displayed. Is there a way I could display Jon Smith?
I thought their might be a way to use Full Name or First and Last Name.
