ORA-00984 在 PL/SQL 过程中不允许列答案

【问题标题】：ORA-00984 column not allowed here in PL/SQL procedureORA-00984 在 PL/SQL 过程中不允许列
【发布时间】：2013-11-15 13:04:41
【问题描述】：

create or replace procedure pro_enroll(sname_in IN varchar, cname_in IN varchar)
as
sno STUDENT.snum%type;
begin
    SELECT snum INTO sno FROM STUDENT WHERE sname=sname_in;
    --dbms_output.put_line(sno || chr(9) || sname_in || chr(9) || cname_in);
    INSERT INTO ENROLLED(snum, cname) VALUES(sno, c_name_in);
end pro_enroll;
/

SELECT * FROM ENROLLED;

begin
pro_enroll('M.Lee', 'CS448');
pro_enroll('A.Smith', 'ENG320');
end;
/

SELECT * FROM ENROLLED;

为什么我会收到“ORA-00984 column not allowed here”？在已注册：

CREATE TABLE ENROLLED
(
snum INTEGER NOT NULL,
cname VARCHAR(30) NOT NULL,
PRIMARY KEY (snum, cname),
FOREIGN KEY (snum) REFERENCES STUDENT(snum),
FOREIGN KEY (cname) REFERENCES CLASS(cname) 
);

【解决方案1】：

您在INSERT 中使用了c_name_in 参数名称，但是，您的过程参数的实际名称是cname_in，在c 和name 之间没有_ 符号，这作品：

create or replace procedure pro_enroll(sname_in IN varchar, cname_in IN varchar)
as
sno STUDENT.snum%type;
begin
    SELECT snum INTO sno FROM STUDENT WHERE sname=sname_in;
    --dbms_output.put_line(sno || chr(9) || sname_in || chr(9) || cname_in);
    INSERT INTO ENROLLED(snum, cname) VALUES(sno, cname_in);
end pro_enroll;
/
