如何在 PL/SQL 中使用包内的过程

Question

如何创建一个包含过程的包？程序将指定和激励作为输入，并通过添加给定指定的激励来更新员工工资。显示已更新的员工记录数，例如“更新了 3 条员工记录”。 我有一个表 EMPLOYEE，包含 EMP_ID、EMP_NAME、SALARY 和 DESIGNATION。 给定的功能要求是：

Package name as  EMP_DESIGNATION, and
Procedure signature:
EMP_DETAILS(design employee.designation%TYPE, incentive number);

我尝试的代码是-

set serveroutput on;
CREATE OR REPLACE PACKAGE EMP_DESIGNATION AS
 PROCEDURE EMP_DETAILS(
design employee.designation%TYPE,
incentive NUMBER) IS
BEGIN
UPDATE employee SET employee.salary = employee.salary + incentive
WHERE employee.designation = design;
dbms_output.put_line(SQL%ROWCOUNT || ' employee record(s) are updated');
END EMP_DESIGNATION;
END;
/

输出是-

Warning: Package Body created with compilation errors.
BEGIN
*
ERROR at line 1:
ORA-04063: package body "P10017.EMP_DESIGNATION" has errors
ORA-06508: PL/SQL: could not find program unit being called:
"P10017.EMP_DESIGNATION"
ORA-06512: at line 2

如何解决这个错误？请帮忙。先感谢您。 PL/SQL：语句被忽略

你必须先创建一个包规范，然后是它的body。像这样的：

SQL> CREATE OR REPLACE PACKAGE emp_designation
  2  AS
  3     PROCEDURE emp_details (design employee.designation%TYPE, incentive NUMBER);
  4  END emp_designation;
  5  /

Package created.

SQL> CREATE OR REPLACE PACKAGE BODY emp_designation
  2  AS
  3     PROCEDURE emp_details (design employee.designation%TYPE, incentive NUMBER)
  4     IS
  5     BEGIN
  6        UPDATE employee
  7           SET employee.salary = employee.salary + incentive
  8         WHERE employee.designation = design;
  9
 10        DBMS_OUTPUT.put_line (
 11           SQL%ROWCOUNT || ' employee record(s) are updated');
 12     END emp_details;
 13  END emp_designation;
 14  /

Package body created.
