遇到符號？

Question

CREATE OR REPLACE FUNCTION F5 
    (tstg IN stage.numerostage%type) 
    return sys-ryfcursor 
DECLARE 
BEGIN 
    OPEN list for 
     SELECT count(*) as nbrmodule,sess.* 
    from session sess natural join enseigne 
    where numerostage=tstg; 
    RETURN list;   
END; 

我得到這個錯誤：

encountered the symbol

Answer 1

有多種錯誤在功能。

sys-ryfcursor

這是SYS_REFCURSOR。

DECLARE

您不需要DECLARE關鍵字。去掉它。

的建議，總是編譯你的代碼，並使用SHOW錯誤在的SQL * Plus或類似的客戶端看到完整的錯誤堆棧。如果您發佈它的完整版

例如，

SQL> CREATE OR REPLACE 
    2 FUNCTION F5(
    3  tstg IN stage.numerostage%type) 
    4  RETURN SYS-ryfcursor 
    5  DECLARE 
    6  BEGIN 
    7  OPEN list FOR SELECT COUNT(*) 
    8  AS 
    9  nbrmodule,sess.* FROM session sess NATURAL JOIN enseigne WHERE numerostage=tstg; 
10  RETURN list; 
11  END;
