Question

我在这里做错了什么？

创建一个接受部门编号的程序，计算该部门的基本工资总额，并显示部门编号和基本工资总额。

CREATE OR REPLACE PROCEDURE DEPT_TOTAL_SALARY AS 
BEGIN
   SELECT DEPARTMENTS.DEPARTMENTS_ID, SUM(SALARY) AS TOTAL_SALARIES
   FROM EMPLOYEES, DEPARTMENTS
   WHERE EMPLOYEES.DEPARTMENT_ID = DEPARTMENTS.DEPARTMENT_ID
   DBMS_OUTPUT.PUT_LINE (‘*** TOTAL SALARY CALCULATED ***’);
END;
/

第6行出错：PL / SQL：ORA-00933：SQL命令未正确结束


来自员工，部门

WHERE EMPLOYEES.DEPARTMENT_ID = DEPARTMENTS.DEPARTMENT_ID

DBMS_OUTPUT.PUT_LINE（' *总计计算* '）;

END;

如果DeptNum为30，下面的查询代码会执行以下操作吗？如果没有，我如何根据上面的EMPLOYEES表编写代码来计算每个部门的所有工资？

 DeptNum    Total_Salary
--------    ------------
      30     34,200.00

CREATE OR REPLACE PROCEDURE Dept_Total_Salary (deptNum NUMBER)
        AS
          total_salary NUMBER(12, 2);
        BEGIN
          SELECT SUM(Salary)
            INTO total_salary
            FROM Employees
            WHERE Department_ID = deptNum;
          DBMS_OUTPUT.PUT_LINE('Department ' || deptNum || ' salary is ' || total_salary);
        END;

Answer 1

薪水和部门编号都在EMPLOYEES表中，因此无需在查询中包含DEPARTMENTS表。

您的查询中的错误是：

您不接受部门编号作为存储过程的参数。
当您不需要时，您将包含DEPARTMENTS表。
您没有使用WHERE条款按部门编号进行过滤。
您需要在变量中选择总薪水才能打印出来。
SELECT查询后您需要一个分号。

尝试这样的事情：

CREATE OR REPLACE PROCEDURE Dept_Total_Salary (deptNum NUMBER)
AS
  total_salary NUMBER(12, 2);
BEGIN
  SELECT SUM(Salary)
    INTO total_salary
    FROM Employees
    WHERE Department_ID = deptNum;
  DBMS_OUTPUT.PUT_LINE('Department ' || deptNum || ' salary is ' || total_salary);
END;

编辑：在END之后忘记了分号，在我指出你错过了分号之后 - 哎哟！

Answer 2

接受部门编号

你做错的第一件事就是忽略了这方面的要求。您需要编写一个带有部门编号的过程，并使用where子句来限制从表中检索的内容。

Answer 3

这是我解决这个问题的方式。

CREATE TABLE proTable -- create new table to store sum of sal for each dept
    (deptno NUMBER,
    sumSal NUMBER);

CREATE OR REPLACE PROCEDURE display_dept_sal_sum (v_deptno NUMBER)
AS 
BEGIN
        INSERT INTO proTable (deptno,SumSal)
        SELECT v_deptno,SUM(sal) 
        FROM employees 
        WHERE deptno = v_deptno;
END;

EXECUTE  display_dept_sal_sum(40);
SELECT * FROM proTable;

创建一个存储过程，接受并计算该部门的总工资，并显示部门＃＆amp;总薪水
