The following example creates a OracleParameter and sets some of its properties.

Public Sub CreateOracleParameter()  
   Dim parameter As New OracleParameter("DName", OracleType.VarChar, 14)  
   parameter.IsNullable = True  
   parameter.Direction = ParameterDirection.Output  
End Sub  
public void CreateOracleParameter()   
   OracleParameter parameter = new OracleParameter("DName", OracleType.VarChar, 14);  
   parameter.IsNullable = true;  
   parameter.Direction = ParameterDirection.Output;  


Null values are handled using the DBNull class.
