Clears the current Recordset object and returns the next Recordset by advancing through a series of commands.
Set recordset2 = recordset1.NextRecordset( RecordsAffected )
Returns a Recordset object. In the syntax model, recordset1 and recordset2 can be the same Recordset object, or you can use separate objects. When using separate Recordset objects, resetting the ActiveConnection property on the original Recordset (recordset1) after NextRecordset has been called will generate an error.
Note This parameter only returns the number of records affected by an operation; it does not return a count of records from a select statement used to generate the Recordset.
Use the NextRecordset method to return the results of the next command in a compound command statement or of a stored procedure that returns multiple results. If you open a Recordset object based on a compound command statement (for example, "SELECT * FROM table1;SELECT * FROM table2") using the Execute method on a Command or the Open method on a Recordset, ADO executes only the first command and returns the results to recordset. To access the results of subsequent commands in the statement, call the NextRecordset method.
As long as there are additional results and the Recordset containing the compound statements is not disconnected or marshaled across process boundaries, the NextRecordset method will continue to return Recordset objects. If a row-returning command executes successfully but returns no records, the returned Recordset object will be open but empty. Test for this case by verifying that the BOF and EOF properties are both True. If a non–row-returning command executes successfully, the returned Recordset object will be closed, which you can verify by testing the State property on the Recordset. When there are no more results, recordset will be set to Nothing.
The NextRecordset method is not available on a disconnected Recordset object, where ActiveConnection has been set to Nothing (in Microsoft Visual Basic) or NULL (in other languages).
If an edit is in progress while in immediate update mode, calling the NextRecordset method generates an error; call the Update or CancelUpdate method first.
To pass parameters for more than one command in the compound statement by filling the Parameters collection, or by passing an array with the original Open or Execute call, the parameters must be in the same order in the collection or array as their respective commands in the command series. You must finish reading all the results before reading output parameter values.
Your OLE DB provider determines when each command command in a compound statement is executed. The Microsoft OLE DB Provider for SQL Server, for example, executes all commands in a batch upon receiving the compound statement. The resulting Recordsets are simply returned when you call NextRecordset.
However, other providers may execute the next command in a statement only after NextRecordset is called. For these providers, if you explicitly close the Recordset object before stepping through the entire command statement, ADO never executes the remaining commands.
