This method clears all the roles in the roles collection.

Declaration

// C#
public void clear();

Exceptions

InvalidOperationException - It is thrown when the connection is already open.

Remarks

This method only clears entries from the OracleRoleCollection object associated with the OracleConnection object. After clearing the roles and then opening a connection, ODP.NET does not enable nor disable any session roles due to the empty OracleRoleCollection object. For a session to have no roles enabled, add NONE to the OracleRoleCollection object.
