执行包时出错

2021-12-24 00:00:00 syntax-error oracle stored-procedures plsql

表格结构:

Name       Null Type         
---------- ---- ------------ 
DPT_NO          NUMBER       
SALARY          NUMBER(10)   
PERIOD          VARCHAR2(10) 
START_DATE      DATE         
END_DATE        DATE

包装:

CREATE OR REPLACE package body salary_sal AS
   PROCEDURE find_sal(c_dpt_no salary.dpt_no%TYPE) IS
   c_sal salary.salary%TYPE;
   BEGIN
      SELECT salary INTO c_sal
      FROM salary
      WHERE c_dpt_no= 108;
      dbms_output.put_line('Salary: '|| c_sal);
   END find_sal;
END salary_sal;

在上面执行时出现以下错误

while executing above I'm getting following error

Error: PL/SQL: Compilation unit analysis terminated
Error(1,14): PLS-00201: identifier 'SALARY_SAL' must be declared
Error(1,14): PLS-00304: cannot compile body of 'SALARY_SAL' without its specification.

推荐答案

您缺少包的声明.这个想法是将包的声明(标题"，如果你愿意的话)分开，以便其他包/过程/函数可以从主体(实现)中针对它进行编译.

You're missing the declaration of the package. The idea is to separate the declaration of the package ("the header", if you will), so other packages/procedures/functions can compile against it from the body (the implementation).

在你的情况下，你需要这样的东西:

In your case, you'd need something like:

CREATE OR REPLACE package salary_sal AS
   PROCEDURE find_sal(c_dpt_no salary.dpt_no%TYPE);
END salary_sal;

现在，一旦包被声明，你就可以创建它的主体:

Now, once the package is declared, you can create its body:

CREATE OR REPLACE package body salary_sal AS
   PROCEDURE find_sal(c_dpt_no salary.dpt_no%TYPE) IS
   c_sal salary.salary%TYPE;
   BEGIN
      SELECT salary INTO c_sal
      FROM salary
      WHERE c_dpt_no= 108;
      dbms_output.put_line('Salary: '|| c_sal);
   END find_sal;
END salary_sal;
