Recordset.Updatable Property (DAO)

  • 아티클

Returns a value that indicates whether you can change a DAO object. Read-only Boolean.

Syntax

expression .Updatable

expression A variable that represents a Recordset object.

Remarks

Snapshot- and forward-only–type Recordset objects always return False.

Many types of objects can contain fields that can't be updated. For example, you can create a dynaset-type Recordset object in which only some fields can be changed. These fields can be fixed or contain data that increments automatically, or the dynaset can result from a query that combines updatable and nonupdatable tables.

If the object contains only read-only fields, the value of the Updatable property is False. When one or more fields are updatable, the property's value is True. You can edit only the updatable fields. A trappable error occurs if you try to assign a new value to a read-only field.

Because an updatable object can contain read-only fields, check the DataUpdatable property of each field in the Fields collection of a Recordset object before you edit a record.
