ADO Field Object Attributes Property

For a Field object, the Attributes property is read-only, and its value can be the sum of any one or more of these FieldAttributeEnum values:


Value	Description
adFldMayDefer	The field is deferred; that is, the field values are not retrieved from the data source with the whole record, but only when you explicitly access them.
adFldUpdatable	The field can be written.
adFldUnknownUpdatable	The provider cannot determine if the field can be written.
adFldFixed	The field contains fixed-length data.
adFldIsNullable	The field accepts Null values.
adFldMayBeNull	You can read Null values from the field.
adFldLong	The field is a long binary field. Also indicates that you can use the ADO Field Object AppendChunk Method and ADO Field Object GetChunk Method methods.
adFldRowID	The field contains some kind of record ID (record number, unique identifier, and so forth).
adFldRowVersion	The field contains some kind of time or date stamp used to track updates.
adFldCacheDeferred	The provider caches field values and subsequent reads are done from the cache.

Attributes Property Remarks (ADO Field Object)

Use the Attributes property to set or return characteristics of Field objects.

When you set multiple attributes, you can sum the appropriate constants. If you set the property value to a sum including incompatible constants, an error occurs.
