備註
當您建立的 OracleDataAdapter實例時,下列讀取/寫入屬性會設定為其預設值,如數據表所示。
屬性 | 預設值 |
---|---|
MissingMappingAction | MissingMappingAction.Passthrough |
MissingSchemaAction | MissingSchemaAction.Add |
您可以透過個別呼叫 屬性來變更這些屬性的值。

備註
這個建構函式的實作 OracleDataAdapter 會將 SelectCommand 屬性設定為 參數中指定的 selectCommand
值。
當您建立的 OracleDataAdapter實例時,下列讀取/寫入屬性會設定為其預設值,如數據表所示。
屬性 | 初始值 |
---|---|
MissingMappingAction | MissingMappingAction.Passthrough |
MissingSchemaAction | MissingSchemaAction.Add |
您可以透過個別呼叫 屬性來變更這些屬性的值。
