TableDef.RefreshLink method (DAO)
Applies to: Access 2013, Office 2013
Updates the connection information for a linked table (Microsoft Access workspaces only).
expression A variable that represents a TableDef object.
To change the connection information for a linked table, reset the Connect property of the corresponding TableDef object and then use the RefreshLink method to update the information. Using RefreshLink method doesn't change the linked table's properties and Relation objects.
For this connection information to exist in all collections associated with the TableDef object that represents the linked table, you must use the Refresh method on each collection.
This example uses the RefreshLink method to refresh the data in a linked table after its connection has been changed from one data source to another. The RefreshLinkOutput procedure is required for this procedure to run.

Set dbsCurrent = OpenDatabase("DB1.mdb") ' Create a linked table that points to a Microsoft ' SQL Server database.
