Indicates the name of the provider for a Connection object.
Settings and Return Values
Sets or returns a String value that indicates the provider name.
Use the Provider property to set or return the name of the provider for a connection. This property can also be set by the contents of the ConnectionString property or the ConnectionString argument of the Open method; however, specifying a provider in more than one place while calling the Open method can have unpredictable results. If no provider is specified, the property will default to MSDASQL (Microsoft OLE DB Provider for ODBC).
The Provider property is read/write when the connection is closed and read-only when it is open. The setting does not take effect until you either open the Connection object or access the Properties collection of the Connection object. If the setting is not valid, an error occurs.
