        username = name.Text
 
        Query = "SELECT [username] FROM [customer] where [username] = '" & username & "' "
        dr = db.executeQuery(Query)
        If dr.Read = True Then
            e.Cancel = True
 
            errmsg.Text = "<h5 style='color:#270000;'> The User Name you have entered is already exists.Please enter another  User Name.</h5>"

A view is, in essence, a virtual table which is based on SQL SELECT query. It does not physically exist. A view is an object that can derive data from one or more tables. For Eg Suppose there is a Users Table named customer which has some 100 columns and your wish to create a view with just the userName column

 Help with Code Tags 
 sql Syntax (Toggle Plain Text) 
CREATE VIEW view_UserNames AS
SELECT UserName
FROM customer
CREATE VIEW view_UserNames AS
SELECT UserName
FROM customer

Now rather than using the customer table you can use the view 'view_UserNames' in you code.
