例: 複数のANY IN TABLE句を使用した関数マッピング - Advanced SQL Engine - Teradata Database

この関数マッピング定義には、2つのANY IN TABLE句が含まれます。

関数処理中に、相関名を持たない最初の2つのON句は、2つのANY IN TABLE句に対応します。

CREATE FUNCTION MAPPING user_Attribution
   FOR attribution MAP JSON ( '{ "function_version": "1.0" }') 
   USING
      ANY IN TABLE,
      ANY IN TABLE,
      conversion IN TABLE,
      excluding IN TABLE,
      optional IN TABLE,
      model1 IN TABLE,
      model2 IN TABLE,
      EventColumn, TimestampColumn, WindowSize;

これらのテーブルは、user_Attribution関数マッピングの2つのANY IN TABLE句に対応しています。

SELECT * FROM user_ATTRIBUTION(
    ON attribution_sample_table1 PARTITION BY user_id 
                                 ORDER BY time_stamp
    ON attribution_sample_table2 PARTITION BY user_id 
                                 ORDER BY time_stamp
    ON conversion_event_table AS conversion DIMENSION
    ON excluding_event_table AS excluding DIMENSION
    ON optional_event_table AS optional DIMENSION
    ON model1_table AS model1 DIMENSION
    ON model2_table AS model2 DIMENSION
USING
    EVENT_COLUMN_NAME ('event')
    TIMESTAMP_COLUMN_NAME ('time_stamp')
    WINDOW('rows:10&seconds:20')
    ) as dt ORDER BY user_id, time_stamp;
