错误(8,1):PLS-00103:遇到符号"SET"
Error(8,1): PLS-00103: Encountered the symbol "SET"
我正在尝试使用 oracle 创建一个函数,它应该可以正常工作,但我不断收到以下错误:
Error(8,1): PLS-00103: Encountered the symbol "SET"
here is my Function:
CREATE OR REPLACE FUNCTION CountViewers(nameofPlay plays.play%TYPE) RETURN NUMBER AS
NUM NUMBER;
BEGIN
SELECT SUM(registerd) INTO num1 FROM plays WHERE play=nameofPlay;
return num;
END;
SET SERVEROUT ON;
DECLARE
inc integer;
res NUMBER;
invalid_status EXCEPTION;
CURSOR clients2 IS SELECT * FROM plays;
name_of_play plays.play%ROWTYPE;
play_name plays%TYPE;
BEGIN
inc:=0;
name_of_play := '&Play';
OPEN clients2;
LOOP
FETCH clients2 INTO play_name;
IF name_of_play != play_name.play and clients2%rowcount>i THEN
inc:=inc+1;
ELSIF name_of_play = play_name.play THEN
EXIT WHEN clients2%found;
ELSE
RAISE invalid_status;
--like throw error
END IF;
EXIT WHEN clients2%notfound;
END LOOP;
res:=CountViewers(name_of_play);
DBMS_OUTPUT.PUT_LINE(name_of_play ||' | '|| res);
EXCEPTION
WHEN invalid_status THEN DBMS_OUTPUT.PUT_LINE('The name of play is not found');
END;
问题是你把这个命令放在哪里:SET SERVEROUT ON;
因为它在函数声明里面。
你应该尝试把它放在函数之外:
SET SERVEROUT ON;
