mssql 2000 运行存贮过程时出错，请帮助看一下，谢谢！
----在sqlquery 中运行结果：提示“从字符串转换为 datetime 时发生语法错误。
感到奇怪的是定义参数中没有日期类型的呀！

exec user_info_ADD '1','2','3','4','5','6','7','8','9','10'
出错提示：
服务器: 消息 241，级别 16，状态 1，过程 User_info_ADD，行 20
从字符串转换为 datetime 时发生语法错误。

------存贮过程如下
create PROCEDURE User_info_ADD
@userno varchar(10),
@username varchar(50),
@userpwd varchar(6),
@Empname varchar(50),
@userrole varchar(50),
@usersts varchar(10),
@startdate varchar(8),
@enddate varchar(8),
@regioncode nchar(10),
@deptno nchar(10)

AS

INSERT INTO [gy_User_info](
[userno],[username],[userpwd],[Empname],[userrole],[usersts],[startdate],[regioncode],[deptno],[enddate]
)VALUES(@userno,@username,@userpwd,@Empname,@userrole,@usersts,@startdate,@regioncode,@deptno,@enddate
)

------解决方案--------------------
