示例

以下示例创建并 OracleDataAdapter 设置其一些属性。

Public Sub CreateOracleDataAdapter()  
    Dim myOracleConnection As OracleConnection = New OracleConnection("Data Source=Oracle8i;Integrated Security=yes")  
    Dim custDA As OracleDataAdapter = New OracleDataAdapter  
    custDA.MissingSchemaAction = MissingSchemaAction.AddWithKey  

    custDA.SelectCommand = New OracleCommand("SELECT DeptNo, DName FROM Dept", myOracleConnection)

注解

创建实例 OracleDataAdapter时，以下读/写属性将设置为其默认值，如表所示。

属性	默认值
MissingMappingAction	`MissingMappingAction.Passthrough`
MissingSchemaAction	`MissingSchemaAction.Add`

可以通过对属性的单独调用来更改其中任何属性的值。
