Todos los objetos Recordset se construyen con registros filas y campos columnas. Hay cinco tipos de objetos Recordset :. Este tipo corresponde a un cursor de conjunto de claves ODBC.

Devuelve o establece el objeto Recordset o Recordset de ADO que representa el origen del registro para el objeto especificado. La propiedad Recordset devuelve el objeto Recordset que proporciona los datos que se examinan en un formulario, informe, control de cuadro de lista o control de cuadro combinado. Si un formulario se basa en una consulta, por ejemplo, hacer referencia a la propiedad Recordset equivale a clonar un objeto Recordset mediante el uso de la misma consulta. Requery es posible que el formulario se desenlace. Por ejemplo:. El siguiente ejemplo usa la propiedad Recordset para crear una nueva copia del objeto Recordset a partir del formulario actual y posteriormente imprime los nombres de los campos en la ventana Debug. En el ejemplo siguiente se usa la propiedad Recordset y el objeto Recordset para sincronizar un conjunto de registros con el registro actual del formulario.

Every workbook, document, userform, sheet, classmodule has its own codemodule. If you use 'early binding' it can be done very densely in one line using this code in the declaration area. It always supports bookmarks and therefore allows all types of movement through the Recordset. Some other properties are only readable if the field contains some data. The Fields collection is the default member of the Recordset object. When a Recordset object is passed across processes, only the rowset values are marshalled, and the properties of the Recordset object are ignored. To execute a query without using a Command object, pass a query string to the Open method of a Recordset object. The Mode property governs access permissions. Note If you use variables to represent a Recordset object and the Database object that contains the Recordset , make sure the variables have the same scope, or lifetime. When you create a record, it immediately consists of an item with all predefined fields. This improves performance in situations where you need to make only a single pass through a Recordset.
