ANSWER: - check the connection string. If there are any escape chars then make sure you have them correct for the language you are using.
VB "Server=mycomputer\myinstance"
C# "Server=mycomputer\\myinstance"
C# @"Server=mycomputer\myinstance"

I have an excel file.The data is in range B5:L618 and range has head.The sheet name is sheet1.I do the following to get columns info.
DataTable dt = new DataTable();
dt = myConn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,
new object[] {null, null, tblName, "TABLE"});
I set the tblName to [sheet1$B5:L618]
When I bind dt to DataGrid,DataGrid is empty.
I think the problem is tblName doesn't exist.How should I do?

Hello All,
I took the backup of a database in SQL-Server 2000.
The machine just got shut down because of lack of power supply.
After that when I tried to restore the database, then the following message came:Microsoft SQL-DMO (ODBC SQLState: 42000). An internal consistency error occurred. Contact technical support for assistance. Restore database is terminating abnormally.
I gave the path of database-backup file correctly and I also gave the RESTORE Command properly.
Can anyone suggest me how to fix this error.
Thanks,

Does anyone know how I can put a constrain on a temporary table? I put a constraint on it just fine, but a problem occurs when two users call the proc at the same time it tells me that the object already exists in the database.
***Edit
I forgot to mention its SQL Server 2003.

Hi there,
I am trying to create a DDL trigger here is the code.
CREATE TRIGGER DDLTRIGGER ON DATABASE
FOR DDL_DATABASE_LEVEL_EVENTS
AS
DECLARE @eventData XML
SET @eventData = EventData()
INSERT DDLEVENTLOG
(EVENTTYPE
)
VALUES
(
CONVERT (NVARCHAR(100), @eventData.Query('data(//EventType)'))
)
But its throwing an error when i would run this query.
Here is the error
Msg 227, Level 15, State 1, Procedure DDLTRIGGER, Line 6
"Query" is not a valid function, property, or field.

SELECT A.SRNO, COALESCE(A.STATUS, B.STATUS)
FROM A
INNER JOIN B ON A.SRNO = B.SRNO
COALESCE will return the first non-NULL from its parameters.

Hello,
I have no idea anymore 
Has someone an idea how I can create a backup of my database in SQL Server Express 2005?
I don't know - there is no tool which provide this function. I also haven't the Enterprise Manager.
Is there someone who can recommend a Backuptool?
Thanks for helping...;)

Microsoft makes a graphical management tool available, SQL Server Management Studio Express[^]. I believe you should be able to make a backup from there. This is currently a Community Technology Preview release; there should be a final supported release available soon.
Otherwise the built-in solution is the BACKUP DATABASE command.
Stability. What an interesting concept. -- Chris Maunder

Hello,
Like Mike said about SQL Server Management Studio Express, you right click on the database you'd like to backup, click on Tasks, and then select Backup. At this point you'll see the backup dialog that is similar to Enterprise Manager.
Hope this helps,
Paul

Hi
Dim Command1 As SqlCommand = New SqlCommand("Select Sum (DocSize) AS myDocSize From Document")<br />
Dim MyDocSize As Integer<br />
<br />
Command1.CommandType = CommandType.Text<br />
Command1.Connection = SQLConnection1<br />
myDataSet = New DataSet("myDataSet")<br />
SQLAdapter1.SelectCommand = Command1
This Query returns a value but I am having real trouble working out how to get that figure into a text field in a Label1.Text
The Table has several values that I add up and want the result to be in the Text Label.
New to VB.Net Newer to SQL
Please Help...

As your SQL command only returns a single value, there is no need to attempt to get the value into a DataSet.
IDBCommand, which is the interface implemented by SQLCommand, contains a method called ExecuteScalar[^]- this will return the first value in a select list typed as a generic object. Now, as we know your value will be numeric its just a case of casting the return to the correct type. Say your DocSize is int, the SUM value will also be as such.
Dim Command1 As SqlCommand = New SqlCommand("Select Sum (DocSize) AS myDocSize From Document")<br />
Command1.CommandType = CommandType.Text<br />
Command1.Connection = SQLConnection1<br />
SQLConnection1.Open()<br />
Dim MyDocSize As Integer = CType(ommand1.ExecuteScalar(),Integer)<br />
SQLCOnnection1.Close()<br />

SQL is a declarative language for issuing commands to relational database systems (RDBMS). Though different brands of RDBMS implement their own flavors of SQL, they typically support a standardized usage of a set of commands for retrieving and modifying data.
There are many tools available for dynamically constructing charts from data, be it retrieved from an SQL query or otherwise. For desktop use, there's always Microsoft Excel. If you're making a WinForms or Web application, there are numerous controls out there that perform charting. Google will help you find a bunch.

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
how to make the sql server setting allow the remote connection?

Hi All
New to .Net even newer to SQL.
I need to count a column in a table and add up number of times a value appears.
e.g.
Cat
Cat
Cat
Dog
Dog
Cow
Cat = 3
Dog = 2
Cow = 1
I am writing in VB.Net a reporting tool to query the DB. With this query I want to list each unique value (Cat,Dog,Cow) in a ListView with the corresponding value next to it.
I hope this makes sense....
Thanks

You can use GROUP BY to group your result based on the animal, and use COUNT to get the number of animals of the same type, e.g.:
SELECT animal, COUNT(*)<br />
FROM animaltable<br />
GROUP BY animal
It will return something like:
Cat 1
Dog 2
Cow 3

Try this
suppose table name is 'table' and column name is 'animal'
select animal,count(animal) from table group by animal
hope yours problem will be solved.

I need to run a SQL statement in a C# Windows Forms program using SQLDataFillAdapter. I am binding a SQL statement to a DataGrid. I would like to give the user the ability to click a button to kill the SQL statement if it runs to long. I can't figure out how to do it.
If I run the SQL in a separate Thread, the SQL Thread never blocks (i.e. never returns control back to the Main Thread) in order to allow a button click. So this doesn't seem to be the solution.
Has anyone accomplished what I am trying to do or have any advice?
Thanks,
Mark Mokris

Hi Everybody,
I have read that ADO.net uses disconnected architecture.i.e it gets disconnected from database and gets connected only while updating and retrieving data. If it is true then y do we require to close connection using cn.close.
2) and what is the difference between ASP.net with VB.net and ASP.net with c#. Why is the later one so popular.
Thanking you and waiting for some kind replies.
Bye
Amit

You don't require to, but it is good practice in my opinion.
Amit R wrote: and what is the difference between ASP.net with VB.net and ASP.net with c#. Why is the later one so popular.
Your second question is off topic for this forum, but anyway.... ASP.NET has no differences between C# and VB.NET. It is the same framework regardless of language. You could write it in Fujitsu COBOL (as it now targets the .NET Framework) if you really wanted to. The only differences are in the languages themselves and on the whole those are relatively minor.
As to why C# appears to be more popular? I can't say I'd noticed. They seem to be fairly evenly matched to me.
