Have you installed a named instance? If so, then you need to specify the name as well as the machine.

Hi Colin Angus Mackay,
I used default instance (MSSQLSERVER) when installing the server. I think there's no problem with TCP port or remote connections(no firewall,my computer and server are in the Wide area network).
The server is also running in SQL authentication mode. That's why I gave username sa and password when adding new registration.
Following are all the complicated steps I must do to add new registration:
Ping SERVERNAME to check connection
Add new registration, using SA and SApassword
The previous step failed, then run windows explorer (\\SERVERNAME)
Put windows logon info: SERVERNAME\trunghd & mypassword
Add new registration again and it's successful
If I add registration from some server that I've already entered windows logon info once, it's successful too.
The question is why I have to give Windows logon information to the server when it's running in SQL authentication mode. I found no relation between my Windows username in this server with the installed SQL server in it.
Thank you very much for your answer.

HI All,
I have a frustrating problem with continual login failures with SQLExpress 2005.
I have an application that behaved until yesterday when I started adding some extra Crystal reports.
I get either of two errors:
1. "Cannot open user default database. login failed for TECRA\Nigel"
Or
2. some big long system error (32) saying the file is in use.
When first entering VS, I can either create a dataset or open server explorer, but after that trying to do either throw the error(s).
To clear the error i have to close down VS, restart SQL server manager and reset IIS, but it is back next time I try to do anything with the DB.
Folder permissions are OK for both ASP.NET and NETWORK SERVICE. I have even resorted to deleting the new reports and datasets but now I get the errors regardless.
I am sure I must have done something to the DB, or maybe there is a dud connection somewhere, but I have limited knowledge of SQL Server Manager Express so don't know where to look to stop the errors.
Connection string is:
<add name="cs_BigShakti" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\SHAKTI.MDF;Integrated Security=True;User Instance=True; Connect Timeout=30;Initial Catalog=SHAKTI" providerName="System.Data.SqlClient"/>
Many thanks in advance,
Nigel

Hi,
How can I create a DTS Package using Sql-DMO in a Stored Procedure. I am
using Sql Server 2000.
Saswat.

1-To connect to the distribution database and provide published data to the DTS package (source connection), a special OLE DB provider, the Microsoft SQL Server Replication OLE DB Provider for DTS is used. When you create a transformable subscription, this provider is installed automatically on the
DTS package, and cannot be changed. This provider can be used only with transformable subscriptions.
The connection from the DTS package to the Subscriber (destination connection) does not use the Microsoft SQL Server Replication OLE DB Provider for DTS; it uses whatever OLE DB provider is required to connect to the Subscriber. For example, you would use the Microsoft OLE DB Provider for SQL Server to send transformed data to a Microsoft® SQL Server™ 2000 Subscriber.
2-Only SQL Server (the Microsoft OLE DB Provider for SQL Server) Subscribers and other OLE DB Subscribers can use transformable subscriptions; ODBC Subscribers will not work with transformable subscriptions.

I'm writing an ASP .NET 2.0 application, and I have the following code:
Public Function GetRow(ByVal Id As Guid) As DataRow
Return Me.mDataSet.Table(0).Rows.Find(Id)
End Function
But an exception is thrown at the line: Return Me.mDataSet.Table(0).Rows.Find(Id). I copy the exception details bellow:
Error de servidor en la aplicación '/Proyecto03'.
--------------------------------------------------------------------------------
Se esperaban los valores 2 para la clave indizada, pero se han recibido valores 1.
Descripción: Excepción no controlada al ejecutar la solicitud Web actual. Revise el seguimiento de la pila para obtener más información acerca del error y dónde se originó en el código.
Detalles de la excepción: System.ArgumentException: Values 2 expected, but instead values 1 were received
This is anoying, because the Find method has two overloaded versions: one accepts an Object as parameter and the other accepts an array of Object, so a Guid object should pass without problems. The only thing that comes to my mind is this: There is a special way to make it with the Guid type, but I can't find anything neither the MSDN Library, nor the internet.
Please, help!!!
Bye

To tell you the truth I dont understand any of that!
but as far as ur error is concerned I think what ur doin is that you're passing a single object of GUID type to Find and if you see its discription it says that the method takes the primary key value. I think your primary key must be something else and its datatype is not GUID hence the error... (I can be wrong too coz its an assumption)

Have you installed the MySQL provider libraries on the server? .NET does not support MySQL out-of-the-box, as far as I know.

I'm having to store the Year-End associated with accounts. While there is a static list of 12 dates that have been provided for me, the final day of each month, I wondering about what year value to use when I store these values into a database with a datetime type. I will be using the value to initialise other datetime types for specifying date ranges for subsequent query operations. For example, consider an account that is define to have a year-end of May 31. If I have to provide quarterly information on this account, then going forward I will be generating date ranges such as June 1 2007 to August 31 2007, September 1 2007 to November 30 2007 and December 1 2007 to February 29 2008. I now how I'm going to be generating these date ranges, but just wondering if there is a best practice for stroing year end dates where you ignore or don't care about the year value? Thanks.

You may want to look at AdventureWorksDW DimTime table. Its a OLAP concept where you use a DayTimeKey to refer to a lookup table DimTime for actual date and other pre-aggregated data.
You might be able to insert just one date for every day with FiscalYear and then use
SELECT [FiscalYear]
FROM [dbo].[DimTime]dt
INNER JOIN MyTable t1 ON CONVERT(varchar(23), t1.DateColumn, 101) = dt.[FullDateAlternateKey]
CREATE TABLE [dbo].[DimTime]
(
[DayTimeKey] [bigint] IDENTITY(1,1) PRIMARY KEY NOT NULL,
[FullDateAlternateKey] [datetime] NULL,
[DayNumberOfWeek] AS (datepart(weekday,[FullDateAlternateKey])),
[DayNameOfWeek] AS (datename(weekday,[FullDateAlternateKey])),
[DayNumberOfMonth] AS (datepart(day,[FullDateAlternateKey])),
[CalendarYear] AS (datepart(year,[FullDateAlternateKey])),
[MonthName] AS (datename(month,[FullDateAlternateKey])),
[MonthNumberOfYear] AS (DATEPART(mm, [FullDateAlternateKey])),
[CalendarQuarter] [tinyint] NULL,
[CalendarYear] [char](4) NULL,
[CalendarSemester] [tinyint] NULL,
[FiscalQuarter] [tinyint] NULL,
[FiscalYear] [char](4) NULL,
[FiscalSemester] [tinyint] NULL
)

Thanks for the comment, Dave. That looks to be a little more than what I'm after, but it has given me an idea of using a separate table to contain all of the date ranges I may every use and then have an identifer map to the date range.

Hi.
How can I select some (5 for example) random record from a table?
i.e I want to select 5 records in random from a table ?
Best wishes
|
|
|
|

Use the function NEWID() to calculate a GUID for each row and sort by that.
SELECT TOP 5 *
FROM [MyTable]
ORDER BY NEWID()

I do something similar; I have a table with two columns, one for IDs and one for random numbers.
The benefits are:
A) I don't have to add a column to the main (Employee) table
B) I can weight the selection process; that is, some records (employees) may have multiple entries
in the "hat", or none at all
The table is normally empty, but when it's time to select (Employee) records, I populate it, and make my selections (after an employee is selected I remove all the entries for that employee).
Then I clear the table again when selecting is complete.
One could also add a column to indicate that that ID has already been selected, and after selections delete the non-selected rows, leaving a table with the selected IDs which can then be used in a join.
|
|
|
|
|
My idea is to get the max and min ID's from that Table.
Then use the Math.Random Function and give the limits in that range taken in previous step.
Select 5 Random ID's this way
Then select those records using this kindof construct in your where clause
ID IN(rand1,rand2,rand3,rand4,rand5)
Hope that's helpful for u

That'll work; unless IDs have been removed or deactivated or something.
Maybe select ten random numbers in the range and use TOP 5.
Or loop until you have five.

Sure I can, done it many times, but not on a steep ladder.

Hi,
I have a table with column named EmpID, EmpName, Salary,
I want to find out second highest salary.
Thanks![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
|
|
|
|

SELECT MAX(Salary)
FROM [EmployeeTable]
WHERE Salary < (SELECT MAX(Salary) FROM [EmployeeTable])
|
|
|
|
|
thanks for your help.
Now I have a query that if I want find 3rd highest or 4th highest salary then how to write query?
thanks!
|
|
|
|
|
select TOP 5 salary,empID
FROM EMP
Order by Salary DESC
Use this to find whatever number of top salaried personeel u want. Use a Cursor to fetch the records one by one. In this way u can ignore the records you dont want. Like for finding the 4th highest salary you can ignore the 1st 3 records and get the fourth one.

No need to use a cursor. Here is a query to get the fifth salary.
SELECT TOP 1 Salary, EmpId
FROM
(SELECT TOP 5 Salary, empID
FROM EMP
Order by Salary DESC) AS TopSalary
ORDER BY Salary ASC

I have an ntext column in a table. I wanted this column value to be uploaded to a text file. I was using some code of my own, but it is not working out.Does anybody has any pointers on this? Any simple method to do this programmatically would be highly appreciated. I need to pull this code in one of my button click event on a windows page.
Thanks in Advance!

I am trying to create a reporting system which will give me the "Customer ID", "Number of Messages sent", "Is Message a part of a thread or Distinct", Message Status (i.e. New, Under Review, Cancelled or Resolved) within a given period. I honestly do not see no need for a curso in here but I believe one can be used but I do not understand the benefit of using one. The search is working fine except for the last "Select" prior to dropping the table is not providing Distinct User's. Users with multiple messages/Threads are being pulled up as many time as the amount of records found for them. It is the result set from the Last select that is displayed in the GUI.
Any assistance given will be appreciated.

)
Insert into #MS_MessagesFromCustomer(CustomerID, NumOfMessages, Period, ThreadID, MessageStatus)
Select MSM.SenderID, count(MSM.MessageID)Messages, Convert(varchar, MSM.SentDate, 101) [Sent Date],MSM.ThreadID,MST.CurrentStatusID [Current Status]
