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，它会显示一个错误，上面写着：
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。这个存储过程的功能是接受 3 个用于更改密码的输入、一个用户名、一个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 & 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.

请帮忙，我还在学习存储过程，所以我还不习惯。任何帮助将不胜感激，谢谢！
