How to: Create, Alter, and Remove a View in Visual Basic .NET
This section describes how to create, alter, and remove a foreign key by using Visual Basic .NET.
The code sample shows how to create a view of two tables by using an inner join. The view is created using text mode so the TextHeader property must be set.

myview = New View(db, "Test_View", "Sales")
'Set the TextHeader and TextBody property to define the view.
myview.TextHeader = "CREATE VIEW [Sales].[Test_View] AS"
myview.TextBody = "SELECT h.SalesOrderID, d.OrderQty FROM Sales.SalesOrderHeader AS h INNER JOIN Sales.SalesOrderDetail AS d ON h.SalesOrderID = d.SalesOrderID"
