Examples

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

Public Sub CreateOracleParameter()  
   Dim parameter As New OracleParameter("pDName", OracleType.VarChar)  
   parameter.IsNullable = True  
   parameter.SourceColumn = "Description"  
   parameter.SourceVersion = DataRowVersion.Current  
   parameter.Direction = ParameterDirection.Output  
End Sub  
public void CreateOracleParameter()   
{  
   OracleParameter parameter = new OracleParameter("pDName", OracleType.VarChar);  
   parameter.IsNullable = true;  
   parameter.SourceColumn = "Description";  
   parameter.SourceVersion = DataRowVersion.Current;  
   parameter.Direction = ParameterDirection.Output;  
}  

Remarks

This property is used by the UpdateCommand during the DbDataAdapter.Update to determine whether the original or current value is used for a parameter value. This lets primary keys be updated. This property is set to the version of the DataRow used by the DataRow.Item[String, DataRowVersion] property (DataRow indexer), or the DataRow.GetChildRows method of the DataRow object.
