A dynaset can be updated if the file is not locked or opened for ReadOnly.
What is DAO Recordset in VBA?
Remarks. You use Recordset objects to manipulate data in a database at the record level. When you use DAO objects, you manipulate data almost entirely using Recordset objects. A dynaset-type Recordset object can contain fields from one or more tables in a database. This type corresponds to an ODBC keyset cursor.
What is a dynaset type Recordset?
A dynaset-type Recordset object is a dynamic set of records that you can use to add, change, or delete records from an underlying database table or tables. A dynaset-type Recordset object can contain fields from one or more tables in a database. This type corresponds to an ODBC keyset cursor.

Like the table-type Recordset object, a dynaset retrieves the full record only when it’s needed for editing or display purposes. To create a dynaset-type Recordset object, use the OpenRecordset method on an open database, against another dynaset- or snapshot-type Recordset object, on a QueryDef object, or on a TableDef object.
How are recordset objects created in Microsoft Access?
When creating a Recordset object using a non-linked TableDef object in a Microsoft Access workspace, table-type Recordset objects are created. Only dynaset-type or snapshot-type Recordset objects can be created with linked tables or tables in Microsoft Access database engine-connected ODBC databases.
What are snapshots and dynasets in MS Access?
When working with forms in Microsoft Access, you have the option to create a snapshot link or a dynaset link. Snapshots and dynasets are the two types of Recordset objects from which forms can be based. The recordset type of a form can be determined by viewing the form’s Recordset Type property.
What does the recordsettypeenum constant mean in Microsoft Access?
