Gets or sets the DataRowVersion to use when you load Value.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public override DataRowVersion SourceVersion { get; set; }

Property Value

Type: System.Data.DataRowVersion
One of the DataRowVersion values. The default is Current.

Implements

IDataParameter.SourceVersion

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 property (DataRow indexer), or the DataRow.GetChildRows method of the DataRow object.

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

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