遇到符号？

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;

我收到此错误：

Answer 1

您的函数中有多个错误。

sys-ryfcursor

我是SYS_REFCURSOR。

声明

您不需要DECLARE 关键字。删除它。

建议，始终编译您的代码并在 SQL*Plus 或类似客户端中使用 SHOW ERRORS 来查看完整错误堆栈。

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;
 12      /
