更正 DB2 存储过程错误

Question

我正在我的 DB2 数据库中创建一个存储过程，这是我的存储过程代码：

    CREATE OR REPLACE PROCEDURE PWDCHANGE (UNAME IN VARCHAR(32), 
                                           OLDPWD IN VARCHAR(32), 
                                           NEWPWD IN VARCHAR(32)) 
    AS
    BEGIN
      IF LOGINTABLE.USERNAME = UNAME AND LOGINTABLE.PASSWORD = OLDPWD THEN
      UPDATE LOGINTABLE SET PASSWORD = NEWPWD;
      DBMS_OUTPUT.PUT_LINE('Password Changed Successfully!');
      ELSE DBMS_OUTPUT.PUT_LINE('Incorrect Old Password Input');
    END IF;
    END;

但是当我在我的 IBM Data Studio 中部署它时，它会显示一条错误消息：

    Deploy SENJOBLADE.PWDCHANGE(VARCHAR(32), VARCHAR(32), VARCHAR(32))

    Running
    SENJOBLADE.PWDCHANGE - Deploy started.
    Create stored procedure returns SQLCODE: -104, SQLSTATE: 42601.
    SENJOBLADE.PWDCHANGE: 1: An unexpected token "VARCHAR" was found following "PWDCHANGE (UNAME IN".  Expected tokens may include:  ",".. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.13.111
    An unexpected token "VARCHAR" was found following "PWDCHANGE (UNAME IN".  Expected tokens may include:  ",".. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.13.111
    SENJOBLADE.PWDCHANGE - Deploy failed.
    SENJOBLADE.PWDCHANGE - Roll back completed successfully.

我不知道为什么 VARCHAR 是一个意外令牌，我不知道要更改什么才能部署我的存储过程。此存储过程的功能是接受 3 个用于更改密码的输入、用户名、当前密码和替换密码，这就是我有 3 个 IN 值的原因。

SENJOBLADE 是我的模式名称，LOGINTABLE 是表名，它有两列，USERNAME 和 PASSWORD 列

我尝试删除 VARCHAR 并显示此错误：

    Deploy SENJOBLADE.PWDCHANGE(IN, IN, IN)

    Running
    SENJOBLADE.PWDCHANGE - Deploy started.
    Create stored procedure returns SQLCODE: -104, SQLSTATE: 42601.
    SENJOBLADE.PWDCHANGE: 2: An unexpected token "BEGIN" was found following "PWD IN) 
            AS
    ".  Expected tokens may include:  ":".. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.13.111

    An unexpected token "BEGIN" was found following "PWD IN) 
            AS
    ".  Expected tokens may include:  ":".. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.13.111

    SENJOBLADE.PWDCHANGE - Deploy failed.
    SENJOBLADE.PWDCHANGE - Roll back completed successfully.

请帮忙，我还在学习存储过程，所以还不习惯。任何帮助将不胜感激，谢谢！

试试Deploy SENJOBLADE.PWDCHANGE(UNAME, OLDPWD, NEWPWD)
