AddNew Method (ADO)
Creates a new record for an updatable Recordset object.
After you call the AddNew method, the new record becomes the current record and remains current after you call the Update method. Since the new record is appended to the Recordset, a call to MoveNext following the Update will move past the end of the Recordset, making EOF True. If the Recordset object does not support bookmarks, you may not be able to access the new record once you move to another record. Depending on your cursor type, you may need to call the Requery method to make the new record accessible.
If you call AddNew while editing the current record or while adding a new record, ADO calls the Update method to save any changes and then creates the new record.
The behavior of the AddNew method depends on the updating mode of the Recordset object and whether you pass the Fieldlist and Values arguments.
In immediate update mode (in which the provider writes changes to the underlying data source once you call the Update method), calling the AddNew method without arguments sets the EditMode property to adEditAdd (an EditModeEnum value). The provider caches any field value changes locally. Calling the Update method posts the new record to the database and resets the EditMode property to adEditNone (an EditModeEnum value). If you pass the Fieldlist and Values arguments, ADO immediately posts the new record to the database (no Update call is necessary); the EditMode property value does not change (adEditNone).
In batch update mode (in which the provider caches multiple changes and writes them to the underlying data source only when you call the UpdateBatch method), calling the AddNew method without arguments sets the EditMode property to adEditAdd. The provider caches any field value changes locally. Calling the Update method adds the new record to the current Recordset, but the provider does not post the changes to the underlying database, or reset the EditMode to adEditNone, until you call the UpdateBatch method. If you pass the Fieldlist and Values arguments, ADO sends the new record to the provider for storage in a cache and sets the EditMode to adEditAdd; you need to call the UpdateBatch method to post the new record to the underlying database.
The following example shows how to use the AddNew method with the field list and value list included, to see how to include the field list and value list as arrays.
create table aa1 (intf int, charf char(10)) insert into aa1 values (2, 'aa') Dim cn As New adodb.Connection Dim rs As New adodb.Recordset Dim cmd As New adodb.Command cn.ConnectionString = "Provider=SQLOLEDB;Data Source=alexverb2;uid=sa;pwd=foo$bar00;" cn.Open rs.Open "select * from xxx..aa1", cn, adOpenKeyset, adLockOptimistic Dim fieldsArray(1) As Variant fieldsArray(0) = "intf" fieldsArray(1) = "charf" Dim values(1) As Variant values(0) = 4 values(1) = "as" rs.AddNew fieldsArray, values rs.Update
