Then an ADODB.Recordset object rs is created and the SQL query is executed using the Open method, storing the query result in the Recordset. Next, a Do While loop is used to iterate through each record in the Recordset, retrieving the field values of each record using the Fields property. For each record, processing can be done as needed. After processing a record, the MoveNext method is used to move the Recordset to the next record until rs.EOF is True, indicating that the entire Recordset has been traversed. Finally, the Recordset and database connection are closed to release resources.<\/p>\n<p>Please note that the above examples assume the use of a Microsoft Access database (.mdb file), if using a different type of database, the connection string needs to be modified. Additionally, the SQL query and code for retrieving field values need to be adjusted according to your table structure and field names.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In VB, you can use loops to iterate through ADODB.Recordset objects to retrieve information from a table.
