這個演示程序向你展示了如何計算列表預(yù)覽控件欄的總數(shù)。 - You can add a named calculation , which is a sql expression that is represented as a calculated column , to a table in a data source view
可以向數(shù)據(jù)源視圖的表中添加命名計算，命名計算是一個表示為計算列的sql表達式。 - You can also change the friendly names of columns , define calculated columns , and join tables or views in the data source view to increase their user - friendliness
此外，還可以更改列的友好名稱，定義計算列，以及聯(lián)接數(shù)據(jù)源視圖中的表或視圖以提高其用戶友好特性。 - Can contain relationships , primary keys , object names , calculated columns , and queries that are not present in an underlying data source and which exist separate from the underlying data sources
