Student Score Position
StudentA 56 4

I need to create the positions based on the scores of the ctudents.
I will appreciate any assistance.

Hello,
I am having an issue with a SQL query I wrote in SQL 2000. I am almost there but am lacking in one area, hoping a better programmer than me and a fresh set of eyes can pick off my mistake.
The goal is very straight forward, order and rank the following fields:
R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference
The issue lies in my sub query in the AND / OR joins... This query will work if I sort and rank on two fields, but if I try three or more it does not work properly.
Here is my entire query:
SELECT
TOP 100 PERCENT
R1.AutoPoolID,
R1.PoolType,
R1.Week,
R1.Username,
R1.TieBreakerTotal,
R1.Wins,
R1.Losses,
R1.Ties,
R1.TBActual,
R1.TBDifference,
R1.WinPercentage,
R1.Points_Thursday,
R1.Points_Saturday,
R1.Points_Sunday,
R1.Points_Monday,
R1.Points_Total,
(
SELECT COUNT(*)
FROM tblWeeklyStandings_All R2
WHERE R2.AutoPoolID = R1.AutoPoolID AND R2.Week = R1.Week AND
(
R2.PSWins > R1.PSWins OR
R2.PSWins = R1.PSWins AND
R2.PSPoints_Total > R1.PSPoints_Total OR
R2.PSPoints_Total = R1.PSPoints_Total AND R2.PSTBDifference < R1.PSTBDifference
)
) + 1 AS Rank
FROM dbo.tblWeeklyStandings_All R1 INNER JOIN
dbo.qryUsers_SDR ON R1.AutoPoolID = dbo.qryUsers_SDR.AutoPoolID AND R1.PoolID = dbo.qryUsers_SDR.PoolID
WHERE
(R1.PoolType = '2007' OR R1.PoolType = '2008') AND
(dbo.qryUsers_SDR.OrderBy1 = '6') AND
(dbo.qryUsers_SDR.PointSpread = 1)
ORDER BY R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference
At this point I am ready to buy SQL 2005 because I think this gets easier, hoping a 2000 wiz can help me correct my error, or missing "(", or something!
Here are the results:
Rank Username Wins Points TB Difference
1. test 0618084 16 50 0
4. test 0618083 16 50 66
3. test 0618081 15 50 55
4. test 0618082 14 50 55
5. admin 2 0 0
As you can see the ranking is not correct. It should be the following:
Rank Username Wins Points TB Difference
1. test 0618084 16 50 0
2. test 0618083 16 50 66
3. test 0618081 15 50 55
4. test 0618082 14 50 55
5. admin 2 0 0
Sometimes it works sometimes it does not, frustrating!
In different scenerios, I am ranking the following way when ties occur. My code sometimes does this correctly but as you can see above it fails in certain areas, like it forgets R1.PSWins DESC, R1.PSPoints_Total DESC, R1.PSTBDifference....
Rank
1 Tied
1 Tied
3
4
5 Tied
5 Tied
5 Tied
8
etc...
The most frustrating thing is the sort order is correct, it is the rank sub query that fails under certain scenerious...
Hello-
I was wondering if someone could help me out. What would be the best way for me to go about determining the sale number from the following table:
applicantID calltime result
1 1/5/05 no sale
1 1/15/05 no sale
1 1/25/05 sale
1 1/26/05 no sale
12 1/5/05 no sale
12 1/15/05 no sale
12 1/16/05 no sale
12 1/25/05 sale
12 1/26/05 no sale
the resulting query would provide:
applicantID saleattempt
1 3
12 4
etc. Ultimately, I am trying to figure out how many attempts needed to make a sale.
Thank you...

Hi all,
I am writing an application that is required to create specific Databases on the fly.
I am coding with PHP and have no troubles in creating DB's, example code as follows:
//Create new DB
$create_db = "CREATE DATABASE " . $_POST['name'] . "
ON
( NAME = " . $_POST['name'] . "_dat, FILENAME = 'c:program filesmicrosoft sql servermssqldata\" . $_POST['name'] . ".mdf SIZE = 10,MAXSIZE = 50,FILEGROWTH = 5 )
LOG ON
( NAME = " . $_POST['name'] . "_log, FILENAME = 'c:program filesmicrosoft sql servermssqldata\" . $_POST['name'] . ".ldf',
SIZE = 5MB,MAXSIZE = 25MB,FILEGROWTH = 5MB )";
The problem occurs when I try to view the database through a third party application (MSSQL Manager), it wont appear until its registered.
Therein lies my problem, how to register the database via code or scripts.
Am I even on the right track here?

I have created a view in MS SQL2000 as followed:
Select order_NO, shiptoname, Shiptoaddress, Shiptocity,shiptostate, shiptozip,
EMAILaddress

View 2 Replies View RelatedHaving problem completing this query. I have a list of items. Some items need to be grouped by a list, some by a range. I was thinking of useing two tables, one for the items, and one for the groups. The groups would have something like groupid, title, listnumbers, rangelow, and rangehigh. The tables are in sql database. For example:
The list of items numbers are 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20. In the group table, it would be listed like this:
G1, Group1, 1,,
G1, Group1, 6,,
G2, Group2, ,2,5
G3, Group3,6,18,20
G3, Group3,7,15,17
G3, Group3,8,14,16
G3, Group3,9,11,13
In this example, Group1 is a list, group2 is a range, and group3 is a list of ranges. I can make a query that pulls all the items just in the groups:
SELECT ECC_ITEMS.NBR, Group.Group_Name, Group.Title, ECC_ITEMS.DESCR, ECC_ITEMS.REG_PRC
FROM Group, ECC_ITEMS
WHERE ECC_ITEMS.NBR Between Group.RangeLow And Group.RangeHigh Or ECC_ITEMS.NBR=Group.GroupItems
Now, I am not sure how to put the rest of the items (the ones that aren't in a group) in that query. I was thinking on making a union and the second query being a unmatched query. Not sure how to make it were that query is "unmatched" with a table in the same query. And ideas on how to make the second part of the union query?
I was wondering what kind of SQL statement I would need to do the following:For example I have a table that has an ID (vID) column, product id (vPID) and a timestamp (vTime). What I essentially want to do is go through this table and find the top 10 instances of any vPID. I will illsutrate it below.- vID vPID vTime 1 25 101012323 2 25 101012323 3 09 101012323 4 25 101012323 5 25 101012323 6 11 101012323 7 25 101012323 8 10 101012323 9 10 101012323 10 25 101012323 11 25 101012323 12 25 101012323 13 25 101012323 14 11 101012323 15 25 101012323Now what I want to do is return the top vPID instances from highest to lowest so my output should return 25, 11, 10 etc.I hope what I'm asking made sense to you guys, basically im just looking for the top 10 instances of a any product id (vPID) Thanks.

I have a sales report showing Customer, tons shipped, and sales amount with two parameters: year and month. I want to show the ranking by month by both tons and sales. It is easy enough to sort the results by one of the measures and compute a line number but I can't seem to get the rank function to work to compute the ranking by two different measures.
Any ideas?
Thanks.
I have a table that has several dozen account numbers. In the same table, each account number has several thousand control numbers (apparently the person who designed the DB never heard of Dr. Codd).
Anyway, I want to get the last five created control numbers for each account number. I have a "CreatedDateTime" field that I can use to order the control numbers by creation. I can use the Top and Rank functions to get the last five for an individual account number but I cannot seem to produce a solution with the last five for each account number.
Anyone have any ideas?
Thanks.
in mysql, we can have

Code:
Select id from tbl_account in Game_User DB
id is binary data
USE Billing
INSERT INTO tblUser (userId,cpId,userTypeId,userStatusId,gameServiceId) VALUES ('test','1','1','9','6') where userId = id from tbl_account
and
INSERT INTO tblUserInfo (userNumber,userId,cpId,userTypeId,userStatusId,gameServiceId) VALUES ('123','test','1','1','9','6') where userNumber = userNumber and userId = userId from tblUser
Im new when it comes to making SQL queries, so i need help badly.
Basically what i need the query to do is call from a DB "User" id where the id is in Binary data. from that i need it to insert into 2 other tables in the Billing DB.
the UserId needs to be the same in all areas, and when it inserts into tblUserInfo it has to pull from userNumber from tblUser after the rows are entered so that the userNumber in tblUser and tblUserInfo are the same.
Hopefully you can help. if any further information is needed please just ask and ill try to give as much as i know.
Thanks

I have this database running (ignore that that was done in Access, this is being made in Microsoft SQL Server 2005).
What I need to do is if you look at the tbl_events table and the tbl_timekeeperDetails table I need to make a query that:
Lists the names of all timekeepers (whether they are booked for a meeting or not), and the meetings at which they are timekeeping.
The tricky part of this is getting the query to show the timekeepers who aren't assigned to an event.
I have two seperate querys so far, but I'm presuming there must be a way of merging them or something.
I have this code so far:
select timekeeperTitle,timekeeperNameFirst,timekeeperNameLast,eventID

It would be very much appreciated.
I'm building a standard search function for this project im working on and I wanted to know how could I do the following; Basically want I am using the standard "LIKE" function to search keywords but I also want to rank the returns based on how many matches. For example if someone uses the keywords "dog run park fast" and I have a couple of records that have certain amount combinations with these words, how would I return the one that has the most combinations to the least. If one record had "dog, run,park", another has "dog run" and the last would have "fast". How would I being those results in that order.Thanks for any help.

Here is the origonal post:
"I have a table containing 100 stores, 5000 customers, and the distance between each store and each customer. I am trying to build a query that simply lists each customer and which store is closest and its distance.
Right now it looks like this:
Customer1|store1|33
Customer1|store2|15
Customer1|store3|28
Customer1|store4|35
Customer2|store1|35
Customer2|store2|95
Customer2|store3|28
Customer2|store4|76
I want to get it like this:
Customer1|store2|15
Customer2|store3|28"
Here is the solution:
Code:
SELECT CustomerPost, StorePost, StoreName, Distance
FROM Customer_Store_Distance2 as T
WHERE (Distance =
(SELECT MIN(Distance)
FROM Customer_Store_Distance2
WHERE CustomerPost = T.CustomerPost))
I have query that calculate percentage. i need to rank it to nearest 2 decimal places
query like
SELECT distinct [table a]/[table b] *100 as percentage
from blabla
results
.........
2.7777
20.125
..
want to get result
3
20
how I could achieve a ranking number, where I have some grouping involved.I want to have the groups in sets of 4, but if I get to a new person the ranking increases, even if I haven't filled the group. For example:
Name Year Sales Ranking
-------------------- ----------- ----------- --------------------
John Smith 2009 1296 1
John Smith 2010 1296 1
John Smith 2011 1296 1
John Smith 2012 1296 1
John Smith 2013 1296 2
[code]....
So, when I get to John's 5 year, the Rank increased. I then only had two more rows before I get to Nina, but the Rank number goes up, as the details are for a different person from the prior user.
Select *, DENSE_RANK() over (Order by Name) + ((RANK() over (Partition by Name Order by Year) - 1) /4) as Ranking
from #Test
Order by Name, Year
Drop Table #TestThis works for John, but Nina then has a Ranking of 2 for her only year, where as she should be 3. Steve also then has a value one too low for all of his ranks.
I have a rank column and a column with percents. The higher the percent the better the rank. How would I do this?
