The data as it's recorded in the SQL table looks like this:
IDbatchdate_timecompany_namesymbolscore
4670713/11/14 9:30 AMJ.C. PENNEY COMPANY INC.JCP97
4670813/11/14 9:30 AMZOGENIX INCZGNX97
4670913/11/14 9:30 AMEXCO RESOURCES INCXCO93
4671013/11/14 9:30 AMMARVELL TECHNOLOGY GROUP LTDMRVL91
4671113/11/14 9:30 AMCABOT OIL & GAS CORPCOG90
[code]....
Basically what I'm after, I need to pull only the top 3 records based on score in descending order BUT these should be grouped by batch. For example, I need to select the top 3 records which have the highest score from batch 1, 2, 3, etc. where there could be any number of records in a batch and any number of batches.

I'm trying not to use a temp table, but i may have to do so..
I'm using sql2005 for this case.
i have a derived table that makes the following results:
ID Status Name
2 1 "A"
2 2 "B"
I want to get the following:
ID Name1 Name2
2 "A" "B"
but like I said before, I can't repeat the query that gets the first 2 rows, as it's pretty invovled. a temp table is the best route I see right now, but I just wanted to be sure I'm not missing something. If I've aliased it as 'results', is there a way to alias results again as something else? or maybe a trick with CTEs? I will try that! It seems promising.

Hi,
We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.
If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.
Thanks,
Sarah
The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.
This is running on a Websphere Application Server v6.1.
Code snippet - getting the record thru JDBC:
DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();
// wsCon.setAutoCommit(false); //have tried with and without this flag - same results
Statements stmt = wsCon.createStatement();
String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);
if(rs.next()){
System.out.println(rs.getString("lastName"));
}
if (rs != null){
rs.close();
}
if (stmt != null) {
stmt.close();
}
if (wsCon != null) {
wsCon.close();
}

I have a list that is grouped by Department inside it I have a table with two columns: name and hours. For example:
Department A
Name Houres
Mike 1
Department B
Name Houres
Mike 1
Steve 1
Department C
Name Houres
Mike 1
Steve 1
Outside the list I have another table that has a column for total hours for all departments:
Which in this case is 5. Everything work fine, but I have problem with displaying the total hours for all departments. In other words this will be my output
5
5
5
5
5
5
5
5
5
5
5
5
It will be repeated multiple times. I believe I have to add group to the table that contains the column (total hours for all departments.) but I can€™t do that b/c It is the total for all departments. Also I tried to hide duplicate wich works, but the problem with that when I export it to pdf it will print empty pages.
Any thoughts!
Thanks

This is actually not asp.net, but I'm hoping someone can help me. I have a report that is pulling from a couple of different tables. I am trying to add a meal choice to the report. Let's say they have the option of choosing chicken, beef or fish. They check the checkbox next to the choice. My report is pulling the infor, but it is putting 3 rows for each person not taking into consideration what choice they chose. The checkbox's all write to the same column - ses. Here is the code for the stored procedure:
CREATE PROCEDURE [dbo].[spGetCourseEmailList1]( @Code1 char(9)) AS SELECT DISTINCT dbo.[names].lname as LastName, dbo.[names].fname as FirstName,dbo.[evser].ses as MealChoice,dbo.[evldg].paid as AmountPaid, dbo.[names].gp as PreferredAddress, dbo.[names].mi as MiddleInitial, dbo.[names].nname as NickName, dbo.[names].xname as Suffix, dbo.[names].hphone as HomePhone, dbo.[names].email as EmailAddress, dbo.[names].addr1 as HomeAddress1, dbo.[names].addr2 as HomeAddress2, dbo.[names].city as City, dbo.[names].st as State, dbo.[names].zip as ZipCode, dbo.[firms].fname1 as FirmName1, dbo.[firms].fname2 as FirmName2, dbo.[firms].faddr1 as FirmAddress1, dbo.[firms].faddr2 as FirmAddress2, dbo.[firms].fcity as FirmCity, dbo.[firms].fst as FirmState, dbo.[firms].fzip as FirmZip, dbo.[firms].fphone as FirmPhone, dbo.[names].udflist1 FROM dbo.[firms] INNER JOIN dbo.[names] ON dbo.[firms].firm = dbo.[names].firm
INNER JOIN dbo.evldgON dbo.[names].id = dbo.[evldg].id
INNER JOIN dbo.evregON dbo.[evldg].id = dbo.[evreg].id
Full OUTER JOIN dbo.evserON dbo.[evreg].code1 = dbo.[evser].code1
WHERE dbo.[evldg].code1 = @Code1 AND dbo.[evreg].code1 = @Code1 AND dbo.[evser].code1 = @Code1 AND dbo.[names].xwebflag <> 'Y'ORDER BY dbo.[names].lname, dbo.[names].fnameGO
The items in bold are what I added.

When using Access - you had to be careful about the autoincrement feature. If you delete a record from a table ( autoincrement id=1000) -then compact/repair - then add a new record to that table - the autoincrement field will say 1000 - if that autoincrement value was used to uniquely identify something - it is no longer unique. This is all background for my question...
Does SQL 2000 do this also ? I must have read somewhere that it doesn't - since I have code that moves records around ( delete from one table - insert into other), but the other night, I was awakened by the thought that SQL2000 does the same as Access - i.e. repeating identity after compact/repair
Do I need to worry ?

Hi everybody!
I've got this little problem.
I need to insert data from a table to another table.
The scenario looks as follows:
I've got 'Company' table (no duplicated records there) and 'Contacts' table (one to many relation: for one company there can be more than one contact).
The following statement retrieves the data but it shows me everything, including all contacts and therefore I get duplicating values, e.g. company name.
Is there any way of changing the following query so it works?
INSERT Projects(
CompanyID,
ContactID,
CustomerName,
EntryTime,
SetupFee,
ForecastRevValue06_07,
ClosureProbabilityID,
ExpectedClosingDate,
TechnologyID,
Service_ProvidedID,
Dropped,
AgreementTerm,
AgreementTermDisplayOnly,
ForecastStartDate,
ForecastEndDate,
LongTerm,
UserID
)
SELECT Distinct
CI.CompanyID,
CC.ContactID,
--CC.FirstName + ' ' +CC.LastName,
getDate(),
0,
0,
5,
DateAdd(month,2,getDate()),
2,
1,
0,
2,
'2 month(s)',
DateAdd(month,2,getDate()),
DateAdd(month,4,getDate()),
0,
2
FROM
CompanyInfo CI
left outer JOIN CompanyContacts CC ON
CC.CompanyID = CI.CompanyID

I am a developer who works with MS SQL Server a lot, but I'm far froman expert. I am revamping an appointment scheduling system thatallows for appointments to reoccur daily, weekly, monthly and yearly.Currently, I am saving the appointment date as the initial appointmentdate. Then when I want to check for appointments, my stored proc doesdoes a select on the appropriate records fitting certain critieria(like only appointments for this doctor, at this location, etc). OnceI have these records I cycle through them calling the DateAdd() andDateDiff() functions to see if the appointment is reoccuring duringthe dates I'm looking for.Here's is a mock up of what I'm doing. I know cursors are a huge hitperformance-wise (especially how they are used in this scenario) andwant to get a way from this, but I can't figure out how to getreoccuring appointments to work. Any help is appreciated. Thanks.sp_GetAppointments(@StartDate, @EndDate)set @DateToCheck = @StartApptDatewhile @DateToCheck <= @EndApptDatebegin--Start a cursorDECLARE RepeatCursor CURSORFORWARD_ONLY STATIC FORselect ApptDate from ApptTable where DoctorID = 1 and--Check if it repeats daily((repeat = 1 andDateAdd(d,DateDiff(d,ApptDate,@DateToCheck),ApptDa te) =@DateToCheckand DateDiff(d,ApptDate,@DateToCheck) >0)--Check if it repeats weeklyor (repeat = 2 andDateAdd(wk,DateDiff(wk,ApptDate,@DateToCheck),Appt Date) =@DateToCheckand DateDiff(d,ApptDate,@DateToCheck) >0)CLOSE RepeatCursorDEALLOCATE RepeatCursorset @DateToCheck = DateAdd(d,1,@DateToCheck)end

Ok, so I've been racking my brains on this one for a while now and figured it was time to ask for some help...
I have a table named tblAppInfo that looks something like this:
Code Block
user_name app_name app_ver
User1 MS Word 2000
User2 MS Word 2000
User3 MS Excel 2000
User4 MS Excel 2000
User5 MS Excel 2000
User6 MS Excel 2000
User7 MS Outlook 2000
User8 MS PowerPoint 2000
User9 Adobe Acrobat 5.0
User10 Adobe Acrobat 6.0
User11 Adobe Acrobat 7.0
What I want to do is remove any rows that repeat the app_name and app_ver more than twice. Basically in the example above, it would remove the lines that have MS Excel 2000 (as it's listed 4 times). MS Word 2000 would stay as it's only listed twice. As would Outlook and PowerPoint. All 3 Adobe's would also stay as their versions are different.
I've tried the following but it still repeats applications that occur more than twice:
Code BlockSELECT user_name, app_name, app_ver
FROM tblAppInfo
GROUP BY app_name, app_ver, user_name
having count(distinct app_name + app_ver + tblAppInfo.host_name) < 3
ORDER BY app_name, app_ver
I've also tried using nested select statements and everything else in my arsenal to no avail. I hope someone here will be able to help me out as I'm afraid I'll go bald if I try anymore!
Thanks in advance!
Tom

Hi
Pulled all my hair out now, can someone please offer some help before I go totally mad...
I have no page header, this is all in the body. I have a List with account number and job number in it at the top, called list1. In list1 I have list2, with the job details, basically a list of people who attended the job. The fields in list2 are textboxes, they're not in a table.
EG:
Acc No: 12345
Job No: 54321
Name
Fred Bloggs
Joe Bloggs
Etc
When my list2 of names goes over 1 page, I want to repeat the account number and job number on each subsequent page. In my real report I actually have 10 fields I want to repeat.
I then want to be able to export this report to a PDF.
I can't put the header in the page header and RepeatWith doesn't work when exporting to PDF, or at all depending on what mood it's in.
Does anyone have a workaround for this please?
Cheers

I have the option for repeating table headers for every page turn on as I would like the table headers repeated on every page. In the HTML report view, this works fine, however when the report is exported to pdf (a total of 80 some pages), when there is a table that contains a lot of data, the table headers are not displayed. I know this could be because the table includes a subreport and sometimes the subreport runs more than one page, but shouldn't the table header still be diplayed on the new page?
Is there something else that I need to check or should I move the table/column header information somplace else?
Thanks for any information.

I have run into a strange issue that I believe is a SQL Reporting Services issue.
I have a report laid out in landscape setting that has 4 columns of text. Two of the columns are sub-reports (due to the complexity and size, we did not flatten out the data in the stored procedure) and two of the columns are regular fields.
The 2 columns of regular fields are smaller, and normally only grow to about 1/2 the height of he page. One of the two sub-reports contains large amounts of text, and at time grows larger than the height of the page.
When the sub-report grows larger than the current page, it correctly starts up on the next page. But the 2 fields of data from the main dataset (not the sub-report columns) repeat themselves on the next page as well.
What is even more strange is the 2 fields of data from the main dataset only repeat data to grow vertically as far as the sub-report needs to grow. So if there is more data in either of these 2 fields than is needed for the sub-report to grow on the 2nd page, it will cut off the data in both of these fields.
I have tried placing the information in a group header. Turned the "Repeat on new page" both True and False, Took away the table header and footer, forced a page break after each group, tried using the "Hide Duplicates" property on the field within the details section, and nothing has seemed to fix the issue.
If anyone has run into this and found a work around, let me know.
Thank you,
T.J.

Hello,
I'm a bit new to MS-SQL so i thought maybe you could help me.
This is my prob. I have an Access application that i have upsized to a MS-SQL server. I have a query based on 3 tables: Customers, Companys and Payreminders. When i run this query, i can't add new records or make any changes.
If i only run the query with the tables: companys and payreminders i can add new records and edit them. If i run a query that's based on companys and customers, i can edit and add new records, but when i run the query based on companys and customers i can't add or edit records.
companys, payreminders: Editable
payreminders, companys: Editable
Companys, customers: Non editable
Companys, payreminders, customers: Non editable
Something must go wrong when i use the companys and customers table. Can anybody help or give a suggestion what to do.
Thanks.

Here's the scenario. Consider the following sample data.
CREATE TABLE #MyTest
(
CustomerNumber INT,
Division CHAR,
SalesRepType INT,
SalesRepNumber INT,
EnterDate DATE
[code]....
Essentially, what I’m attempting to do is for each Customer, Division, SalesRepType determine who the most recent assigned SalesRepNumber is and when (EnterDate) that person was assigned. So using the sample data, I would expect the following results.
CustomerNumberDivisionSalesRepTypeSalesRepNumberAssignedDate
10000A11002/1/2015
10000A23001/28/2015
10000B14002/1/2015
10000B26002/2/2015
I’ve tried various ways of using a CTE and ROW_NUMBER trying to get at this, but the area that is giving me the problem is in Division A, SalesRepType 1. Here is what gets me close, but I’m picking on SalesRepNumber 200 instead of 100 for Division A and
SalesRepType 1.
WITH
cteCust (RowNum, CustomerNumber, Division, SalesRepType, SalesRepNumber, BeginDate)
AS
(
SELECT

I am having problems with a SQL query.
Table has 10 fields and I need to return them all. The three most importaint, at least for the filter I need are:
id, studentid, date, canceled.
I need to return the last max(date) grater than or equal to @dateparam which is not canceled for each studentid
I have worked out some solutions but am not happy with them. Specially woried about performance when the table grows. I am expecting in full production a table growth of about 3 million records per month.
what would be grate is if there where a way of returning a the coresponding id like in:
select studentid, max(date), related(id) as ids
from tablea
where canceled=0
group by studentid
then I could do:
Select *
from tablea inner join (select studentid, max(date), related(id) as ids
from tablea a
where canceled=0
group by studentid
) b on (a.id=b.ids)
