row-number

I've read many articles regarding how to use a row number in SQLite but none of them gave me the answer I need. I know how to select row number using this query: SELECT (SELECT COUNT() FROM table WHERE title < t.title OR (title = t.title AND id<t.id)) as rowIndex, t.title FROM table AS t ORDER BY t.title; but if I add COLLATE NOCASE (which I need) at the end of the query then the result is completely different. Fabian Your query contains an error: the alias "ja" is not defined. Try it like this: SELECT ( SELECT COUNT(*) + 1 FROM "table" WHERE title < t.title OR (title = t.title AND id<t.id) )

I have an application in which I need to display "pages" of data in a list. The basic idea is fairly common. The display shows a list of items and at the bottom of the display are some kind of controls that allow you to go to the next "page" of data. All well and good. I have this working. Following is the SQL in a view I am using to support the "next" behavior. CREATE VIEW CampaignParticipants AS SELECT row_number() OVER (ORDER BY TPT.LastName, TPT.FirstName, TPT.DoB) AS RowNumber ,CGP.* ,TPT.* FROM tblCampaignGEDPush CGP JOIN tblParticipants TPT ON CGP.PartID = TPT.PartID Here is how I use

I need help in writing a query in Oracle for the following data. The data is sorted by Person and Day fields. Person Day Flag ------ --- ---- person1 day1 Y person1 day2 Y person1 day3 Y person1 day4 N person1 day5 N person1 day6 Y person1 day7 Y person1 day8 Y I need to have a Group_Number column that gets incremented whenever the Flag value changes. My result should look as below Person Day Flag Group_Number ------ --- ---- ------------ person1 day1 Y 1 person1 day2 Y 1 person1 day3 Y 1 person1 day4 N 2 person1 day5 N 2 person1 day6 Y 3 person1 day7 Y 3 person1 day8 Y 3 I think there is way

given a query in the form of an ICriteria object, I would like to use NHibernate (by means of a projection?) to find an element's order, in a manner equivalent to using SELECT ROW_NUMBER() OVER (...) to find a specific item's index in the query. (I need this for a "jump to page" functionality in paging) any suggestions? NOTE: I don't want to go to a page given it's number yet - I know how to do that - I want to get the item's INDEX so I can divide it by page size and get the page index. Christoffer Lette After looking at the sources for NHibernate, I'm fairly sure that there exists no such

What is the difference between ROWNUM and ROW_NUMBER ? ROWNUM is a "pseudocolumn" that assigns a number to each row returned by a query: SQL> select rownum, ename, deptno 2 from emp; ROWNUM ENAME DEPTNO ---------- ---------- ---------- 1 SMITH 99 2 ALLEN 30 3 WARD 30 4 JONES 20 5 MARTIN 30 6 BLAKE 30 7 CLARK 10 8 SCOTT 20 9 KING 10 10 TURNER 30 11 FORD 20 12 MILLER 10 ROW_NUMBER is an analytic function that assigns a number to each row according to its ordering within a group of rows: SQL> select ename, deptno, row_number() over (partition by deptno order by ename) rn 2 from emp; ENAME DEPTNO

Until Office 2007, Excel has a maximum of 65,000 rows. Office 2007 bumped that up to a max of 1 million rows, which is nicer of course; but I'm curious -- why is there a limit at all? Obviously, performance will slow down exponetially as you increase the spreadsheet size; but it shouldn't be very hard to have Excel optimize for that by starting with a small sheet and dynamically "re-sizing" it only as needed. Given how much work it must have been to increase the limit from 65K to 1 million, why didn't they go all the way so it's limited only by the amount of available memory and disk space?
