IsComputed Property
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The IsComputed property reports whether the Column object references a computed Microsoft SQL Server column.
Syntax

.IsComputed [=value]
Parts

An expression that evaluates to an object in the Applies To list
- value

Read/write before column creation. Read-only if referencing an existing column.

Hinweise
If TRUE, the referenced column is, or will be created as, a computed column. When creating a computed column, set IsComputed to TRUE and set the ComputedText property to define the column's computed expression.
If FALSE, the Column object references a column that can contain literal values.
