Question

我在SAP HANA中创建了这个sql触发器，无法找出如何引用最后插入的行，这里是触发器的代码：

    CREATE TRIGGER MY_TRIGGER 
    AFTER INSERT ON TARGET_TABLE 
    FOR EACH ROW
    BEGIN
        CALL SOME_PROCEDURE(:NEWROW.id);
    END;

我尝试了REFERENCING NEW ROW语法，但INSERT AFTER触发器似乎不支持。

帮助！

 CREATE TRIGGER TEST_TRIGGER_VAR_UPDATE                   
 AFTER UPDATE ON TARGET                                   
 REFERENCING NEW ROW mynewrow, OLD ROW myoldrow          
 FOR EACH ROW                                             
 BEGIN                                                    
  INSERT INTO SAMPLE_new VALUES(:mynewrow.a, :mynewrow.b); 
  INSERT INTO SAMPLE_old VALUES(:myoldrow.a, :myoldrow.b);
  INSERT INTO SAMPLE VALUES(0, 'trigger');
 END;

如何在sap hana sql触发器中获取最后一行？
