Returns a value that indicates whether the data in the field represented by a Field object is updatable.
Return Values
The return value is a Boolean data type that returns True if the data in the field is updatable.
Remarks
Use this property to determine whether you can change the Value property setting of a Field object. This property is always False on a Field object whose Attributes property is dbAutoIncrField.
You can use the DataUpdatable property on Field objects that are appended to the Fields collection of QueryDef, Recordset, and Relation objects, but not the Fields collection of Index or TableDef objects.
