You can even try this

declare @tblcustomer table(customerid int,customername varchar(50))
insert into @tblcustomer
select 12,'Jone' union all select 25,'Mark' union all
select 25,'Marc' union all select 10,'AJ'

select x.customerid
		,x.customername
		from
		(
	select 
		ROW_NUMBER() over (partition by customerid order by customerid) as rn
		,customerid
		,customername
	from @tblcustomer)X(rn,customerid,customername)
	where rn = 1

Output:

customerid	customername
10	          AJ
12	          Jone
25	           Mark

How do you know which is the first CustomerName? Is the 'first' name always the correct one?

I recommend that you BACKUP the database instead of copying the MDF.

I was trying to backup the database file by copying it from one folder to another, but it is throwing error that file is in use. So I thought of detach it first and then copy.
So How to do this?

The file is in use because the (SQL) server is using it - always. There are some excellent examples of how to take a backup correctly[^] right here on CP

Use this :

BACKUP DATABASE [DataBaseName] 
TO  DISK = N'D:\DataBases\BackupDB.bak' WITH 
NOFORMAT, 
NOINIT,  
NAME = N'DataBaseBackup-Name', 
SKIP, 
NOREWIND, 
NOUNLOAD,  
STATS = 10

Create an object of SqlCommand and pass this as CommandText.
Run this in master Database (I mean the connection object should point to master database)

Use ExecuteNonQuery to take backup to Disk location mentioned.

Can't Create database

Hi

I am trying to create a database using T-SQL and i am getting the following error message.

Msg 5133, Level 16, State 1, Line 1
Directory lookup for the file "C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\saledat.mdf" failed with the operating system error 3(The system cannot find the path specified.).
Msg 1802, Level 16, State 1, Line 1
CREATE DATABASE failed. Some file names listed could not be created. Check related errors.

I am using SQL server express 2005 which I recently installed on a new desktop.

The script I am using to create the database is as follows.

USE master;
GO
CREATE DATABASE Sales
ON
( NAME = Sales_dat,
FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\saledat.mdf',
SIZE = 10,
MAXSIZE = 50,
FILEGROWTH = 5 )
LOG ON
( NAME = Sales_log,
FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\salelog.ldf',
SIZE = 5MB,
MAXSIZE = 25MB,
FILEGROWTH = 5MB ) ;
GO

I don't know what could be causing this error, and I would appreciate any help granted.

Thanks in advance

If you are creating this on a server then make sure that path exists ON THE SERVER.

On my system the path for SQL Express 2005 is:

I ran the script and it created a Sql Server 2008 database in the specified folders. The path the op is using is definitely for 2008, and if he was using a 2005 instance then the default path should have been what you posted - notice no comments from the op for over 4 hours.

Update Master Database Daily comparing with old one

Hi,

We are working with one of the client
We recieve daily updated database from client
We have to compare the old database and the newly records should be updated

Guide me how can we implement this logic in .net or any solution

I'm a bit confused. Confused | :confused:

If you receive an updated database from your client on a daily basis, why don't you just replace the old database with the new one ?

Otherwise, you will need to create a reconciliation program that considers the following:
1) New records
2) Deleted records
3) Update records

You could apply this logic on a table by table basis, but the problem arises when there are constraints among dependent tables. If you try to insert a record in a table and the foreign key does not exist yet in the parent table you will get an insert error.

One method around this is to drop all constraints when performing this reconcilliation and re-apply the constraints when the process is complete.

Not an easy task.
Best of luck.

Assuming that your Database is MS SQL Server and that it is >= 2005, this[^] may be of interest to you.

You send whole database or part of the database means only those items which are updated or changed.

So whats the problem highlighting the XML in management studio right click>Save as...?

Failing that, have a look at SqlCmd from a command prompt. It allows you to execute a query, and output the results to a file.

You can use bcp to create xml in shared folder with Everyone rights and then can use FILE class to move to C:\ drive
