Dear Fellows,

You can create declare connection string in web.config file. You can do so by

<add name="Connection_Name" connectionString="server=(local);database=database_name;uid=sa;pwd=sa" providerName="System.Data.SqlClient"/>

Now you can call this connection in any .aspx page by this command.

NOTE: I am getting connection string in a string variable named "Path"

string path = System.Configuration.ConfigurationManager.ConnectionStrings["Connection_Name"].ConnectionString;

See how simple is this. In the same way you can use this connection string in all your .aspx pages.

Take Care and Enjoy...............

ORA-38104: Columns referenced in the ON Clause cannot be updated

In my case, this error pertains to Oracle Merge query. After 30 minutes of time wastage and a lot of hunting on different forums, I come to know that where and why was my merge query throwing exception.

I hope that this will also works for you.
