Sets or returns a value that indicates one or more characteristics of a Field object.
For a Field object, the value specifies characteristics of the field and can be a sum of any one or more of these FieldAttributeEnum values:
| Constant | Value | Description |
|---|---|---|
| adFldUpdatable | 4 | Indicates that you can write to the field. |
| adFldFixed | 16 | Indicates that the field contains fixed-length data. |
| adFldIsNullable | 32 | Indicates that the field accepts Null values. |
| adFldMayBeNull | 64 | Indicates that you can read Null values from the field. |
| adFldLong | 128 | Indicates that the field is a long binary field. |
In ADO, the following values are always returned: adFldIsNullable, adFldMayBeNull. Other values are determined based on the actual field (adFldLong, adFldFixed) or how the recordset was opened (adFldUpdatable).
