I'm stuck. I have a table that I want to pull some info from that I don''t know how to.
There are two colomuns, one is the call_id column which is not unique and the other is the call_status column which again is not unique. The call_status column can have several values, they are ('1 NEW','3 3RD RESPONDED','7 3RD RESOLVED','6 PENDING','3 SEC RESPONDED','7 SEC RESOLVED').
i.e example, this is the existing data.
Call_id Call_Status
555555 3 3RD RESPONDED
235252 7 SEC RESOLVED
555555 7 3RD RESOLVED
325252 6 PENDING
555555 6 PENDING
325235 3 SEC RESPONDED
555555 1 NEW
This is the data I want...
Call_id Call_Status
555555 3 3RD RESPONDED
555555 6 PENDING
555555 7 3RD RESOLVED
The call_id could be any number, I only want the 6 PENDING rows where there are other rows for that call_id which have either 3 3RD RESPONDED or 7 3RD RESOLVED. If someone knows how it would be a great help.
Cheers,
Chris

Hello,
Does anyone know how to select rows by their position in a table. I need to be able to e.g return the 2,000th - 2,200th rows as a set. I will have many concurrent clients connecting to this table so I do not want to use cursors. The table is 800,000 in length.
Any ideas people?
Thanks,
Alan

Hi,
I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

I have two tables a stock table and a price table and I want to select the correct price for the Stock Date.
Problem is sometimes there is a promotion date in the price table between the live dates so the rows double up. Below is my sql but I get over 17,000 rows when it should be about 16,964.
I will post up the table and data.
SELECT a.[Company]
,a.[ProductID]
,a.[ColourSize]
,a.[StockDate]
,a.[Quantity]
,b.[Ticket Price]
FROM[Stock_Ledger] a
LEFT OUTER JOIN [Product_Prices] b
ON a.[Company] = b.[Company]
AND a.[ProductID] = b.[ProductID]
AND a.[ColourSize] = b.[ColourSize]
AND a.[StockDate] BETWEEN b.[StartDate] AND b.[EndDate]
ORDER BY a.[StockDate],a.[ProductID],a.[ColourSize]

Mike writes "Hi,
I am a beginner with TSQL and I hope this is not a silly question :-)
Lets say I have a table with 2 columns, 1 a primary key identity field with increment 1 and the other a char.
EG:
ID ANIMAL
---------
1 CAT
2 DOG
3 PIG
4 RAT
5 PIG
6 DOG
7 DOG
.
.
And so on with many entries
How do I return a selection of rows that have the contents of the ANIMAL field matching 1 or more times
EG:
From above table I want to return rows 2,6 & 7 and 3 & 5 ONLY and not 1(CAT) and 4(RAT) because they only occur once.
In my real life situation I have unknown numeric data in field 2 but the principal is the same.
How do I do this?
Thanks in Advance

Is it posible on a query ordered by employee name, for exemple, that MSSQL gives me a position of which employee is contained on the recordset?
that's my query (simplified)
SELECT name, payment, category FROM employee_payments ORDER BY name
John, 1000, sallary
Peter, 1500, sallary
Peter, 500, other
Zeus, 1000, sallary
I want to add another field giving me the position of the employee on the recordset:
John, 1000, sallary, 1
Peter, 1500, sallary, 2
Peter, 500, other, 2
Zeus, 1000, sallary, 3
Is it posible?

I got the following query:SELECT TOP (8) ext.extID, ext.Quote, ext.sourceTitle, ext.extRating, gf_game.gameID, gf_game.catID, gf_game.URL, gf_game.TitleFROM gf_game_ext AS ext INNER JOIN gf_game ON gf_game.gameID = ext.gameIDWHERE (ext.Approved = 1)ORDER BY ext.extID DESC which is e.g. producing this output: 6000 -some text- Title 90 1960 2 tom-cl tom cl5999 -some text- title 90 1960 2 tom-clcl asdf5998 -some text- title 90 1959 2 tom-cl-cl asdfWhat I'd like to do now is to filter out the duplicate GameIDs (= 1960) so that just one unique row with the gameid 1960 is remaining. If I put in a SELECT DINSTINCT TOP(8) it just counts for the table ext, but I need it to count for gf_game.gameID - is that possible?Thanks a lot!

Hi all -
is there a way to process a file x records at a time?
We have a table that I need to append to an existing table. The date columns are currently in char but must be converted to datetime for the existing table. The problem is I have bad data. There are 3 million rows where the date field isn't valid for SQL's datetime format. Since this is the data I have, I have to work with it. I would like for SQL to just insert a null if it comes upon a bad date. Currently when it encounters a field that isn't valid, it stops the process with an error.
I have tried to go around it below, but there is still something "hanging" I would like to be able just to insert one million rows at a time and if it errors, then I can look at the next million, find the error, fix it and continue on.
Any suggestions? Or if you have a better idea all together I would love to see it.
SQL Server 7.0, SP2
,CASE
when
(substring(check_date,1,4) not between '1997' and '2000' or
substring(check_date,5,2) not between '01' and '12' or
substring(check_date,7,2) not between '01' and '31') THEN null
ELSE cast(check_date as datetime)
END AS check_date
Thanks,
Michelle

Is there someone out there who has a hint for me???

Here's my current SQL:
SELECT
RN_TEST_ID AS 'Test ID',
MAX(RN_EXECUTION_DATE) AS 'Last Execution Date',
MAX(RN_EXECUTION_TIME) AS 'Execution Time',
RN_DURATION AS 'Run Duration'
FROM RUN
[code]....
Here's a sample of data returned:
Test IDLast Execution DateExecution TimeRun Duration
86722/9/2015 0:0012:08:16180
86822/9/2015 0:0011:29:06181
86842/9/2015 0:0008:29:17119
105252/3/2015 0:0019:03:4089
105252/3/2015 0:0019:10:13305
106682/3/2015 0:0018:55:43103
106682/6/2015 0:0018:10:50123
114572/3/2015 0:0011:40:0726
What I need are two things:
1. The query should only return one record for each test id
2. The record returned should be the most recent. By most recent I mean the RN_EXECUTION_DATE and RN_EXECUTION_TIME of the returned row should be the most recent in time.
For example, in the sample data there are multiple rows with the same test id (for example 10668 and 10525. The 10525 is even more problematic since its execution date is the same for both rows returned - the execution times differ. Again, I want one record per test id and that record should be the most recent in time.

Hi All,
I'm a beginner in SQL and would like some help with writing a query that needs to:
a) Return the latest time that an event happened (along with the event), and also
b) Determine if this event occurred more than 30mins ago.
For example, Table EVENT consists of the following data:
EVENT DateTime,
A 16/1/08, 14:03:55
B 16/1/08, 14:30:27
A 16/1/08, 17:42:18
I would like the results for the first part of query to be:
EVENT DateTime,
A 16/1/08, 17:42:18
B 16/1/08, 14:30:27
I have tried creating a query based off this thread, but for some reason it kept complaining that the EVENT column in Table EVENT didn't exist.
For the part b), I have no clue as to what I should do apart from that I would need to use NOW().
Any help would be appreciated.

Hi guys,
Just trying to select a set of Articles from a SQL Server Database. The Articles all have a Category ID which is stored in another table (as an Article could be in more than one Category). I want to select the Top 3 Articles in a Category. At the moment I have as my SQL;
"SELECT TOP 3 f.ArticleID, f.Heading, f.Summary, f.WrittenDate, f.ArticleURL FROM feedTable f LEFT JOIN Categories c ON f.ArticleID = c.ArticleID WHERE c.CategoryID=" + CategoryID + " AND c.ArticleID<>" + id + " ORDER BY c.CategoryID"
Which seems to work to an extent in that I do get three articles in the same Category appearing. However, there are sometimes duplicates appearing, so I need to incorporate a DISTINCT clause to the above. I'm not sure where to put this in though. Any ideas?
Thanks.

You are given say a pricelist of books. And you have to find out
all possible sets of books, each of them having total sum of book
prices equal to a given number.
set nocount on

if object_id('tempdb..#tt')>0 drop table #tt
create table #t (n int, price int)
insert into #t -- note asc order of book prices
select 1, 1 union all
select 2, 3 union all
select 3, 4 union all
select 4, 5 union all
select 5, 7 union all
select 6, 7 union all

set @s=@s+(select price from #t where n=@n)
insert into #tt select n, price from #t where n=@n
if @s=@sum select * from #tt --- outputting
end
end
set @n=(select min(n) from #tt)
set @s=@s-(select price from #tt where n=@n)
delete from #tt where n=@n
if @s=0 and (select sum(price) from #t where n<@n)<@sum break

I would like to select rows 1 through 100000 from a specific table in one query then 100001 through 200000 in a second query and 200001 through 300000 in a third and so on until I have gone through all rows. There happens to be 424000 in the table I'm working on.
Any help is appreciated.

Hello i currently have a website that has an SQL server 2005 dbs that stores appointments. I would like to do a select statement in my sqldatasource that selects all the records that have an 'appointmentDate' more than 2 weeks after the current date (ie the system date). I am stuck on the SQL statement i need to produce to achieve this. I was thinking along the lines of
SELECT * FROM appointments WHERE appointmentDate > System.Date + 14; However this is clearly not the right SQL statement. Any help would be appreciated.
Many thanks,
James.
