You use Recordset objects to manipulate data from a provider. When you use ADO, you manipulate data almost entirely using Recordset objects. All Recordset objects consist of records rows and fields columns. Depending on the functionality supported by the provider, some Recordset methods or properties may not be available. Recordset is the ProgID that should be used to create a Recordset object. Existing applications that reference the outdated ADOR. Dynamic cursor Allows you to view additions, changes, and deletions by other users; allows all types of movement through the Recordset that doesn't rely on bookmarks; and allows bookmarks if the provider supports them.

In this web page I will only use the With Only dynaset-type or snapshot-type Recordset objects can be created with linked tables or tables in Microsoft Access database engine-connected ODBC databases. You can do that in the second argument of the method. Dynaset-type Recordset— the result of a query that can have updatable records. In this blog post you will learn inner join using lambda queries. There are five types of Recordset objects:. The Type property indicates the type of Recordset object created, and the Updatable property indicates whether you can change the object's records.

Un objeto Recordset representa los registros de una tabla base o los registros que son el resultado de ejecutar una consulta.

Usually done by creating a small array of recordsets CompareBookmarks Method Compares two bookmarks CursorLocation Property Sets or returns the location of the cursor CursorType Property Sets or returns the cursor type of the recordset object Data Member Property Sets or returns the name of the data member that will be retieved from the object referenced by the DataSource property DataSource Property Specifies an onject containing data to be represented as a Recordset object Delete EditMode Property Returns the editing status of the current record EOF Property Returns True if the current record position is after the last record, otehrwise False Exceute Fields Filter Property allows you to restrict the records viewed in a reocrdset GetRows Method Retrieve a specified number of rows from a recordset and returns a Variant array. Filter sets the recordpointer in the first record of the filtered records. Sets or returns a value that specifies the type of locking when editing a recordset object. ActiveX Data Objects
