Computed

When an extended attribute is computed, it is calculated from other values using Get and/or Set VBScript methods.

The computed extended attribute can have the following access types:

Read/Write (Get+Set methods): The read and write access to the extended attribute value is defined by a VBScript Get method and a VBScript Set method.
Read only (Get method): The read only access to the extended attribute value is defined by a VBScript Get method.

Note that a Set method cannot be defined without a Get method.

The computed extended attribute is not saved in the model. When selected, this checkbox triggers the display of the following additional property pages:

Additional tab	Description
Get Method Script	Specifies the body of the Get method, which returns the value of the extended attribute.
Set Method Script	Specifies the body of the Set method, which sets the value of the extended attribute.
Global Script	Specifies functions and static attributes that may be reused among different functions.

Example

In the following script, the FileGroup computed extended attribute gets and sets its value from the physical options of the table object:

Function %Get%(obj)
%Get% = obj.GetPhysicalOptionValue("on/<filegroup>")
End Function

Sub %Set%(obj, value)
obj.SetPhysicalOptionValue "on/<filegroup>", value
End Sub
