how to delete duplicate rows in a table if that tables has no primary key
|
|
|
|
|
The quickest method is to add a primary key to that table. You can always remove it after you've deduped the table.

From the Connection string i gave you. Apply the IP Address of the Server, it will work, as Sitting here am accessing the SQL Database and i used VB.net to my Application to a SQl Server not in my building, its Far in another City. try it and tell me the Errors that you encounter
Dont bother where ever the server may reside in your connection string you just change datasource(server) field
datasource=IP of the server if you are using internet
or
datasource=server name iof you are using local server
connection never changes but make sure that user id and password are correct

hi Vuyiswa,
i already try datasource as u specify. it work well for local server but not for remote server.
i get following error
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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
i don't know where i m wrong ?
is this related to proxy ?
thanks

Your code is Correct there are two or more reason why you Got that Error
Its Eather you Dont have the Correct Credentials to Log in meaning username and password, or you have no permission to the database or table you want to Access. or You hae supplied the Wrong server, or your Server is Down. please send me the code that you wrote and let me see your connection string.

The Code is Correct, make sure you are using the correct IP for the SQL Server,you might find out that, you have been provided with the wrong IP for SQL Server, Make sure the username:havenbar have right to Access the Database you want to counterbar1. But all the rest is Correct.

Welcome,let me ask you. is the SQL server at your client a Dedicated or non Dedicated? , if its non Dedicated he might have gave you the wrong IP,

Have you ever resolved this? If not then I have to ask.....can you telnet to the SQL server from the internet? Also is the router forwarding all packets on 1433 to the SQL server or is this server on the internet with no router at all?

So there's this guy I know and he wants me to teach him data modeling in a nutshell. He asked me to just give him a fast run-down on Primary Keys, Foreign Keys (the difference) and normalization. He's pretty smart so a link to something brief but technical is fine.
...
...
Okay! I'm lying! The guy is me and I haven't done data modeling in years. I'm trying to remember this simple thing. If I have a table called Sequences as an example and I have a table called OrderProcessing and 6 other tables that use Sequences.SequenceId (or a number representing that number in the Sequences table). Do I just make all of them FK's to the Sequences.SequenceId PK?
Does that make sense? I totally need a drug test and I know that...

Father to a murdered process, husband to a murdered thread. And I will have my affinity, in this life or the next. - Gladiator. (Okay, not quite Gladiator but close.)
I work to live. I do not live to work. My clients do not seem capable of grasping this fact.
