SqlServerCe VISUAL STUDIO 2005 VISUAL BASIC help needed.
From an application I get SqlServerCe DATA TABLE with multiple occurrences of the same records. I need VISUAL STUDIO 2005 VISUAL BASIC code to DELETE the records that are written more than once.

Would you not be better just doing the delete in SQL?

Thanks for your reply. I can not do that because the table is the result of a program and is created many times. As many as the program is used. I can not change the program so I need to change the table every time is ceated. Thats why I need to write code in visual studio visual basic to correct the table and eliminate the additional records. I assume there is not a SQL command to do that.

An error has occured 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
|
|
|
|
|
- Open the SQL-Configuration Manager via 'Start->Programs->Microsoft SQL Server 2005->Configuration Tools->SQL Server Configuration Manager'
- Browse to 'SQL Server 2005 Network Configuration->Protocols for MSSQLSERVER' and enable the required protocols (e.g. the TCP/IP-Protocol)
This should solve your problem. If not, you can check the properties of the Server (Right-Click on the registered server in the SQL Management Studio). In the 'Connections' -Tab, check the option
'Allow remote connections to this server'.

Hi
try this query
Select A.id,B.Name,C.Calc From A,B,C Where A.id = B.id And A.id = C.Id
Or
Select A.Id, Name, Calc From A
Inner Join B On B.Id = A.Id
Inner Join C On C.Id = A.Id
Hope this will work but there should be relation between these tables

You need to create a database first. Then you can create the table in the database.

Use the SQL Server Management Studio.

If you wish to become a great dba or even a good one then write your own scripts. To do this effectively you have to use "SQL SERVER BOOKS ONLINE" which are installed with SQLserver 2005. Learn or look at one new command a day and get feel for the commands.
First look up command : CREATE DATABASE
THEN look up command : CREATE TABLE
Have fun you have a good journey ahead of you.

You can eliminate 'Set' and 'exec (@str)' statements by having the select query alone which will get the records of the appropriate user.
select AstID from userTable where userid = @userid and password = @password

I am trying to run a bulk update on a table by picking up the IDs that I've populated onto a table variable based on some criteria.
The update just works fine if the number of records in the table variable are < = 1000.
When this number increases to 5000, the update does'nt work. When I try to debug my code, I get the message box stating "Error while executing 'A Batch Cmd' at line 0; Sql Error: 0 "The statement has been terminated."
On catching this execption I get the message "Timeout expired.The Timeout period elasped prior to completion of the operation of the operation or the server is not responding.\r\n The statement has been terminated."
When I try to run the stored proc from the query analyzer, it keeps processing for a long time and that I've to manually stop the execution.
On trying to run the queries that I have in the stored proc individually did'nt yield me positive results either.
I've ensured that my stored proc meets the specifications listed here[^]
Can anyone throw some light on what can be tried to fix this?
Environment: VS 2005 Pro, Sql Server 2000

Can you post some of the code up here so we can take a look?

Yes,sure. The following lists the logic and flow of my proc.
.... Proc declarations go here ....
Begin Transaction
Declare @tblCategory Table (CategoryID BigInt)
Insert into @tblCategory(CategoryID)
Select A.CategoryID from Shop A Where ProductName = @pProdName
If exists(select categoryId from @tblCategory)
begin
Declare @tblLocalities Table(CategoryID BigInt, LocalityID int)
Insert into @tblLocalities (categoryid,localityid)
select B.CategoryID, B.localityId from ShopGroup B, Shop A
where A.CategoryID = B.CategoryID and A.ProductName = @pProdName
If @@rowcount > 0
begin
Update Shop Set Ranking = 2 where categoryID in
(select t.CategoryID from @tblLocalities t)
end
end
If @@error > 0
Begin
rollback transaction
end
else
begin
commmit transaction
end

I'm trying to understand what your code is trying to achieve. As far as I can work out, the following would do the same:
UPDATE Shop SET Ranking = 2
WHERE CategoryID in (
SELECT B.CategoryID
FROM Shop A
INNER JOIN ShopGroup B
ON A.CategoryID = B.CategoryID
WHERE A.ProductName = @pProdName
)
Is this any faster? How many rows does it update? What is the purpose of linking to "ShopGroup"?
The next step would probably to look at the indexes.
Regards
Andy

Yes, inserting or updating a lot of records will take a lot of time, particularly if running other queries concurrently against the same records (which may temporarily block your updates due to locks). ADO.NET stops your application from being blocked forever by imposing a configurable command timeout, which you set in the SqlCommand's CommandTimeout property. It defaults to 30 seconds, so if your command takes more than 30 seconds to execute you get a SqlException.
Management Studio assumes you're more interested in the results than in a speedy response and doesn't time out.
