Writes all pending batch updates to disk.
recordset.UpdateBatch AffectRecords, PreserveStatus
Optional. An AffectEnum value that indicates how many records the UpdateBatch method will affect.
Optional. A boolean value that specifies whether or not local changes, as indicated by the Status property, should be committed. If this value is set to True, the Status property of each record remains unchanged after the update is completed.
Use the UpdateBatch method when modifying a Recordset object in batch update mode to transmit all changes made in a Recordset object to the underlying database.
If the Recordset object supports batch updating, you can cache multiple changes to one or more records locally until you call the UpdateBatch method. If you are editing the current record or adding a new record when you call the UpdateBatch method, ADO will automatically call the Update method to save any pending changes to the current record before transmitting the batched changes to the provider. You should use batch updating with either a keyset or static cursor only.
Note Specifying adAffectGroup as the value for this parameter will result in an error when there are no visible records in the current Recordset (such as a filter for which no records match).
If the attempt to transmit changes fails for any or all records because of a conflict with the underlying data (for example, a record has already been deleted by another user), the provider returns warnings to the Errors collection and a run-time error occurs. Use the Filter property (adFilterAffectedRecords) and the Status property to locate records with conflicts.
To cancel all pending batch updates, use the CancelBatch method.
If the Unique Table and Update Resync dynamic properties are set, and the Recordset is the result of executing a JOIN operation on multiple tables, then the execution of the UpdateBatch method is implicitly followed by the Resync method depending on the settings of the Update Resync property.
The order in which the individual updates of a batch are performed on the data source is not necessarily the same as the order in which they were performed on the local Recordset. Update order is dependent upon the provider. Take this into account when coding updates that are related to one another, such as foreign key constraints on an insert or update.
