Define SQL Azure View Columns

Use the SQL Azure View Editor to specify the view columns in a SQL Azure physical model. You can create view column references to any table column or view column in your model. By default, the view column name reflects the column name that the view references, but you can change a view column name. You can also reorder view columns, and create and manage view expressions, which are user-defined expressions that are stored as a view column.

To define SQL Azure view columns

1. Click Views on the Model menu.

   The SQL Azure View Editor opens.

2. Select the view in the Navigation Grid for which you want to define a view column.
3. Click the Select tab and work with the following options:

   Available Tables and Views

   Displays the tables or views and associated columns that can be used to define the view column. Click the tables or views that you want and use the arrow buttons to move the selected items from this list over to the Columns list.

   Note: You control the tables and views that display in the Available Tables and Views list using the options in the From tab.

   Columns

   Select Type

   Lets you select a view type that automatically eliminates duplicate rows.

   Restriction Type

   Note: This option is available only if the selected view column is a user-defined expression.
