oracle11g - 创建包 sqlplus

Question

我正在尝试通过以下过程创建一个包

CREATE OR REPLACE PROCEDURE insert_rows
(pl_deptno dept.deptno%TYPE, pl_dname dept.dname%TYPE, pl_loc dept.loc%TYPE
) AS
BEGIN
INSERT INTO dept 
(deptno,dname,loc) 
values ( pl_deptno,pl_dname,pl_loc);
commit;
end insert_rows;
/

到目前为止，这是我的包秒，创建得很好

create or replace package fpf 
is
procedure insert_rows
   (p_deptno IN dept.deptno%TYPE,
    p_dname IN dept.dname%TYPE,
    p_loc IN dept.loc%TYPE);
end fpf;
/

但是，当我创建包体时，出现编译错误，有什么想法吗？

create or replace package body fpf
as
procedure insert_rows
   (p_deptno IN dept.deptno%TYPE,
    p_dname IN dept.dname%TYPE,
    p_loc IN dept.loc%TYPE)
as
BEGIN
INSERT INTO dept 
(deptno,dname,loc) 
values ( pl_deptno,pl_dname,pl_loc);
end insert_rows;
end fpf;
/

当您遇到编译错误时，您需要查看收到的错误。在 SQL*Plus 中，您可以使用命令 showerrors

来做到这一点

SQL> create or replace package body fpf
  2  as
  3  procedure insert_rows
  4     (p_deptno IN dept.deptno%TYPE,
  5      p_dname IN dept.dname%TYPE,
  6      p_loc IN dept.loc%TYPE)
  7  as
  8  BEGIN
  9  INSERT INTO dept
 10  (deptno,dname,loc)
 11  values ( pl_deptno,pl_dname,pl_loc);
 12  end insert_rows;
 13  end fpf;
 14  /

Warning: Package Body created with compilation errors.

SQL> sho err
Errors for PACKAGE BODY FPF:

LINE/COL ERROR
-------- -----------------------------------------------------------------
9/1      PL/SQL: SQL Statement ignored
11/29    PL/SQL: ORA-00984: column not allowed here

这些错误告诉您编译器认为第 11 行第 29 列处的关键字是列名称，并且代码中此时不允许使用列名称。第 11 行第 29 列是 pl_loc 标识符。据推测，您并不打算将其作为对列名称的引用。据推测，您希望将其作为参数的名称。但 Oracle 不将该标识符识别为参数。这是因为您的参数名为 p_loc 而不是 pl_loc(请注意额外的 l)。

如果您更正所有三个参数的名称，代码就会编译

  2  as
  3  procedure insert_rows
  4     (p_deptno IN dept.deptno%TYPE,
  5      p_dname IN dept.dname%TYPE,
  6      p_loc IN dept.loc%TYPE)
  7  as
  8  BEGIN
  9  INSERT INTO dept
 10  (deptno,dname,loc)
 11  values ( p_deptno,p_dname,p_loc);
 12  end insert_rows;
