如何將新老對象引用到存儲過程中？

Question

我有一個觸發器，它看起來象下面這樣：

create trigger theTrig 
insert on table_A referencing new as n 
for each row(
    execute procedure proc_A(); 
); 

我可以知道我可以通過新/舊參考對象爲存儲過程的觸發器內？

Answer 1

CREATE TRIGGER theTrig 
    INSERT ON table_A REFERENCING NEW AS n 
    FOR EACH ROW 
    (
     EXECUTE PROCEDURE proc_A(n.col2, n.col3, n.col5, n.col7, n.col11); 
    ); 

我平時寫 'REFERENCING NEW AS NEW' 和/或 'REFERENCING OLD老' 和Informix是很高興的同義反復規範效勞。
