First/last in a group of
Hello!I have a table with session_ids, url, a user has visited and the time did.
I need output session_id PR.
Session ID, durtaion of the session, the first page he visted, last page, it made
I tried many things with first_value, last_value, first/last in various analytical functions, but my head can't seem to find the right solution.
(aprt of coding it in PL/SQL)
It is an example of my table:
drop table mette_interval;
create table mette_interval (session_i number, varchar2 (400) url, date of url_time);
insert into mette_interval values (1, 'start page', sysdate);
insert into mette_interval values (1, 'xxxxside z', sysdate + interval of second '5');
insert into mette_interval values (1, 'end pagexxxxxside z', sysdate + interval of second '6');
insert into mette_interval values (2, 'page xxx z', sysdate + interval of second '0');
insert into mette_interval values (2, 'yyyy z page', sysdate + interval '10' sec);
insert into mette_interval values (3, 'page some z', sysdate + interval of second '1');
Select session_i, (max (url_time) - min (url_time)) * 24 * 60 * 60 duration
of mette_interval
Session_i group;
Can you give me a hint?

Updated to 4.6 DM, and now Outlook meetings (with the participants) remains in line with harm during synchronization with my 8310. I have synced several times, and it maintains see these different between Outlook and your handheld. The ONLY difference seems to be the order of the names of participants (first, last vs. last, first).
How can I fix it? Thank you
As with most of the problems, you will need to dig a little deeper. Here's how I solved it:
(1) under Options/language there is a setting for the display name. I changed it to "First name" "Last, first".
(2) but then I've always had some problems so I examined the difference in names more in detail (by cut and paste to WORD and then comparing the documents). Here is the ROOT of the problem:
- Several of the guests at the meetings were invited by third parties in Outlook
- I have several of my names of colleagues, phone numbers and the email addresses in my phone Contact list - but not everyone in the company.
- There are several cases where people in the Outlook e-mail database name was DIFFERENT then how I was entered in their names in my phone. If (for example) Robert Jones was in my phone: Bob Jones - but the email addresses are the same of course.
- Apparently with this version of DM (and I've also updated my phone to 4.5.0.81) emails AND THE NAMES are compared and MUST BE IDENTICAL.
The solution was to compare it and then change my Outlook Contact file so that the names are the same as in the corporate e-mail system superior, including initial and same averages the number of spaces between the names!
Once I did, the problem disappeared. Thought I'd document it here, because someone else may have the same problem. This did not appear until I upgraded to 4.6 DM.

Perhaps this example might be useful for you. the code uses the same code that you published with additional analytical query to return the row grouping for the name, the NRP and columns pera. then use that line number to determine which will be placed at the first mark.

Help or advice will be greatly appreciated.
Due to the fact that Oracle does not have the lines in a particular order, it would be wrong that the first 'date' would be the first line to be processed by the query.
So, you will need to provide another column if you do not want to look at the table as ordered by date.
Any analytic function must also allows you to provide the 'to' and if that's the date, then just a simple query:

Best way to details data and show of force only last result in Group
Hi all! First, just let all the world know that it is a great place to explore and learn Oracle - I learned more here than I have in some classes. Come and explore the forums and looking for an answer lead me to the functions that I hadn't known otherwise existed.
Here's what I'm trying to do now... Let's say I have a table that contains information about the family - if two or more persons associated with a family (determined by a separate table) then it should return the person identification and then the details of the group.
For example, the following data are contained in two tables, the follow-up of current results and then the result, that I'm looking...
PERSONS TABLE ---------------------- PERSON PERSON_ID ADDRESS John Smith 101 1 Oracle Drive Jane Smith 102 1 Oracle Drive
A simple query would result in the following text:RELATIONSHIPS TABLE ----------------------------- PERSON_ID RELATEDPERSON_ID 101 102 102 101
RESULTWITH PERSONS AS ( SELECT 'John Smith' AS person, 101 AS person_id, '101 Oracle Drive' AS address FROM dual union all SELECT 'Jane Smith', 102, '101 Oracle Drive' FROM dual ) , RELATIONSHIPS AS ( SELECT 101 AS person_id, 102 AS relatedperson_id FROM dual union all SELECT 102, 101 FROM dual ) SELECT person , address FROM PERSONS p JOIN RELATIONSHIPS r ON r.person_id = p.person_id
I'm looking to produce the following result, but I do not know how... I am convinced that it is something simple.PERSON ADDRESS John Smith 101 Oracle Drive Jane Smith 101 Oracle Drive
DESIRED RESULT
Note that the address for members of the family is not displayed until the last member of the family is returned. It repeats this process for each family.PERSON ADDRESS John Smith Jane Smith 101 Oracle Drive
Thank you all for any help you can provide! 31%

Not only are you things, but the people on this forum are more likely to help you when they see you do everything you can.
If you find something that you are trying to adapt, post a link to it. Seeing the correct way to adapt it can be very instructive.essentially, if I can determine which members of the family someone is, then I can create a unique "FAMILY_ID" for them - once I have that, it would seem that I could then use the FAMILY_ID to combine their addresses and other information.
The problem I have is that if a RELATEDPERSON_ID is linked to a PERSON_ID (PERSON_ID related RELATEDPERSON_ID works very well), he attributes them a new FAMILY_ID, rather than include them in the correct family.
Here is my sql
WITH PERSONS AS ( SELECT 'John Smith' AS person, 101 AS person_id, '1 Oracle Drive' AS address FROM dual union all SELECT 'Jane Smith', 102, '1 Oracle Drive' FROM dual union all SELECT 'Jack Smith', 103, '8 Oracle Drive' FROM dual union all SELECT 'John Doe', 104, '10 Oracle Drive' FROM dual union all SELECT 'Jane Doe', 105, '10 Oracle Drive' FROM dual union all SELECT 'Pete Smith', 106, '1 Oracle Drive' FROM dual ) , RELATIONSHIPS AS ( SELECT 101 AS person_id, 102 AS relatedperson_id FROM dual union all SELECT 102, 101 FROM dual union all SELECT 104, 105 FROM dual union all SELECT 105, 104 FROM dual union all SELECT 106, 101 FROM dual ) , table_x AS ( SELECT person_id AS col1 , relatedperson_id AS col2 FROM relationships ) , got_relatives AS ( SELECT col1 , CONNECT_BY_ROOT col2 AS relative FROM table_x CONNECT BY NOCYCLE col1 = col2 OR col2 = col1 ) SELECT col1 , DENSE_RANK () OVER ( ORDER BY MIN (relative) ) AS family_id FROM got_relatives GROUP BY col1
I think the result is:
COL1 FAMILY_ID ----- ---------- 102 1 106 1 101 1 105 2 104 2
I suspect that whatever you copied originally had the FIRST keyword somewhere in the CONNECT BY clause.
Here's a way to do what you want:
WITH all_relationships AS ( SELECT person_id , relatedperson_id FROM relationships UNION SELECT relatedperson_id AS person_id , person_id AS relatedperson_id FROM relationships ) , got_relatives AS ( SELECT CONNECT_BY_ROOT person_id AS person_id , relatedperson_id FROM all_relationships CONNECT BY NOCYCLE person_id = PRIOR relatedperson_id OR relatedperson_id = PRIOR person_id ) , got_family_id AS ( SELECT person_id , MIN (relatedperson_id) AS family_id , ROW_NUMBER () OVER ( PARTITION BY MIN (relatedperson_id) ORDER BY person_id DESC ) AS r_num FROM got_relatives GROUP BY person_id ) SELECT p.person , CASE WHEN f.r_num = 1 THEN p.address END AS address , p.person_id , f.family_id FROM got_family_id f JOIN persons p ON p.person_id = f.person_id ORDER BY family_id , person_id ;
Output:
PERSON ADDRESS PERSON_ID FAMILY_ID ---------- --------------- ---------- ---------- John Smith 101 101 Jane Smith 102 101 Pete Smith 1 Oracle Drive 106 101 John Doe 104 104 Jane Doe 10 Oracle Drive 105 104
Obviously, you don't have to see all the columns, I posted above in your first post, you said you wanted only person and address. In your last message, you said you wanted only person_id and family_id. change the SELECT main clause just as you wish.
I used the lowest person_id in each family as the family_id. You can use DENSE_RANK if you really want to have families numbered 1, 2, 3,..., but I suspect that you really care what family_id, as long as all the members of the family have the same value.
Table of relationship a you certain symmetrical, such as relationships
SELECT 104, 105 FROM dual union all SELECT 105, 104 FROM dual union all
and a few asymmetric relations. For example, the only relationship involving person_id = 106 is
SELECT 106, 101 FROM dual
in other words, there is no line of mirror-image:
-- SELECT 101, 106 FROM dual union all -- THIS IS NOT IN THE SAMPLE DATA
I guess it didn't matter to that. As long as 101 and 106 appear on the same line, they are in the same family, regardless of the person_id and which is the relatedperson_id.
The first thing I did above was therefore to ensure that all lines of the mirror-image were represented. This is what all_relationships does.
The following subquery, got_relatives, is probably what you mean to adapt, but you let him operators PREREQUISITES.
Got_family_id does the grouping and also calculates r_num to determine which is the last member of the family. Address of this member of the family only will be displayed in the main query.
You could combine got_family_id and the main request; you don't need really a subquery for this. It would be a little less coding, but I wrote it that way because I think it's a little easier to understand and maintain. -
IMAQ edge tool 2 'first + last edge' - returns the position of the first border
I use 'IMAQ edge tool 2.vi' with the whole process in order to detect the 'first and last edge. It is obvious to edge coordinates the infromation seeing that it returns only a single point. Where are the coordinates of the last edge detection?
Note: it detects the edges along the long green horizontal line, so there's at least 2 edges definitevely.
Thanks for the tips.
Martin
Hey Martin,
This may sound silly, but what happens if you scroll down to the following entry in your cluster? Currently, you can view information for your benefit '0' on the front panel. What happens if you are indexing at the edge '1' of your cluster and therefore see the information on the second edge. Is the cluster of empty when you look at the 'zero' edge? If it is, perhaps, the parameters of your step edge find are too strict and the step does not come back on a second advantage.
If the problem persists, maybe post your vi sample and a sample picture will help clear things upward.
I hope this helps!

Last feature via Group Policy user logon
I understand how to turn off the last user logon feature is via group policy if I wanted users to always have to type their user name and passwords by logging into Windows XP or Windows 7 workstations.What I really want to do if I can, is to allow the possibility for the user assigned to the specific workstation to always display their username when they sign in, but if I connect the SysAdmin, I don't want them to see this.So, if I work on their workstations, then logoff or restart, I want for their username to remember and displays not only mine.Is there a way to do this?Hello

Arry.FIRST should be 4, Arry.LAST and COUNT must be 10 and 7 respectively. So how is it random values are to come.
Hello
When you create arry, its NUMBER is 0.
Then you throw in the loop (beginning on line 5) 10 times.
When the 1st time in the loop, I = 1, you add 1 + 3 = 4 points and put the 1 + 3 = a 4th.
The 2nd time in the loop, when I = 2, you add 2 + 3 = 5 points more and put the 2 + 3 = 5.
When the 3rd time in the loop, I = 3, you add 3 + 3 = 6 points more and put the 3 + 3 = 6 a.
...
The 10th time through the loop, when I = 10, you add 10 + 3 = 13 points more and set them 10 + 3 = a 13th.
The other inputs (i.e., 1-3 and 14-85) never get assigned to all values.
4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 = 85.

My address book has 106 names. I selected to sort by ascending by display name. But it will not fully sort this way; on the contrary, the names appear as lots, within each of them, sorting is (mostly) correct. When I click on the name above, sort allows to switch between ascendants and descendants, as expected, but the change occurs within each batch apparent rather than global. Also, it seems that in 1 or several lots, the display name is not what I chose, for example first, change or display.
In other words, display is a long list of names, but it's really defined names, which are treated as such. I want to be in a 'set' and properly sorted as such.
If I understand correctly, modules include different ways to add functionality to Thunderbird. They are Extensions, themes and Plugins. So, you could say that the lightning is a part of the extension of a wider selection of modules.

Problem with sound in the ProRes files on first last, CC on 10 to win
Hello, I've updated my CC Pro first to the latest version on my Windows 10 PC. Since then, I have a problem with the sound in ProRes files recorded with recorder Odyssey 7 q. My first reads the file and it detects sound only partially (in each file it our times of 2-3 seconds of silence, followed by its normal).
It happens only on my first on Windows. On my MacBook with the same version of first, everything works fine. Apart from the first, I play Prores files successfully on my windows (with sound).
You know all the solutions to this problem? I tried to reinstall codec first and Quicktime on my PC. Thanks in advance for the help.
Convergent Design and Adobe are aware of the problem and working on a fix. You need to roll back to 2015.3 for the moment.

Differences in the performance of nividia geforce gtx 860, 870, 880 first last on
Hello guys, I'm about to pass a big load of money on a new laptop and I was wondering how high the power difference of performance between geforce gtx 860 to 870 880 on the latest edition of the first's. It's really the question of the difference in price of about 800 euros, so before decide me on this matter, I would really like to know if it is worth. Once again: there will be a considerable advantage to work first with the geforce 880 or 870 as opposed to 860?
Hope someone can help me here. Thank you
See the compatibility list first. I don't see any of the three top! They CAN work, and I think that these are more recent model processors that are specifically designed for CUDA.
Don't know all about laptops, but on the desktop the other variable (which you don't mention) is the amount of RAM on the video card itself. 800 euros is a huge difference; If the RAM is the same, and all three are on the list of compatibility for playback of mercury, I don't know that you can justify the difference. If the RAM is 1 GB on the cheapest and 4 or 6 on the most expensive, it's a different calculation.
I speculate that the differences between these three cards would be more apparent to players for video editors, but that's just my opinion... what makes the difference in the first is the fact that transcode the video RAM made and perceived effect much faster as the RAM system can, and to do so effectively, it takes like RAM video as much as possible. I think it's the number you want to watch, rather than 860 vs 870 or 880.

It is possible to select more than one layer by selecting the first and the last layers?
I frequently get Illustrator files which are individual objects such as the paths on separate layers that can be grouped together to make the shorter layers. I find that I have to change click on each individual layer to select it to finally bring together them. Sometimes, I have 25 or so layers that I need to select. Is there a way to select the first and the last layer in the layers palette and have Illustrator select all the layers in the meantime?
Don't know about the selection of layers of first/last, but to select several consecutive layers in the layers palette...
Option-click on (Mac) on a layer to select it and, with the option always pressed key, drag to the bottom of the list - DO NOT slip on as logical target icons you like. When you drag to the bottom of the list of layers, the icons of the target will become selected.
Shift + Option-click allows you to ignore the layers and continue to select consecutive additional layers on the bottom of the palette.
Note: Drag slowly or some layers would not choose.
Strange, I know. It took me years to come across this.
