Creates a new Field object (Microsoft Jet workspaces only).
Syntax
Set field = object.CreateField (name, type, size)
The CreateField method syntax has these parts.
Part |
Description |
field |
An object variable that represents the Field object you want to create. |
object |
An object variable that represents the Index, Relation, or TableDef object for which you want to create the new Field object. |
name |
Optional. A Variant (String subtype) that uniquely names the new Field object. See the Name property for details on valid Field names. |
type |
Optional. A constant that determines the data type of the new Field object. See the Type property for valid data types. |
size |
Optional. A Variant (Integer subtype) that indicates the maximum size, in bytes, of a Field object that contains text. See the Size property for valid size values. This argument is ignored for numeric and fixed-width fields. |
Remarks
You can use the CreateField method to create a new field, as well as specify the name, data type, and size of the field. If you omit one or more of the optional parts when you use CreateField, you can use an appropriate assignment statement to set or reset the corresponding property before you append the new object to a collection. After you append the new object, you can alter some but not all of its property settings. See the individual property topics for more details.
The type and size arguments apply only to Field objects in a TableDef object. These arguments are ignored when a Field object is associated with an Index or Relation object.
If name refers to an object that is already a member of the collection, a run-time error occurs when you use the Append method.
To remove a Field object from a Fields collection, use the Delete method on the collection. You can't delete a Field object from a TableDef object's Fields collection after you create an index that references the field.
