一個儲存過程的問題！

儲存過程
我想實現是自動生成一個加Data時間為編號的列，然後把後邊的欄位插到表裡，大家給看下這個過程有什麼問題， 我這邊顯示的錯誤是說什麼varchar轉int是錯誤！
CREATE PROCEDURE insertTest

@name varchar(20),
@regist varchar(10),
@age int,
@password varchar(20),
@weiyibiaoshi varchar(50)=''

OUTPUT
AS
begin
declare

@num int,
@strNum varchar(6),

@Y varchar(4),
@M varchar(3),
@D varchar(3),
@YMD varchar(8),
@Date smalldatetime
set @Date=getdate()
set @Y=Cast(Year(@Date) as varchar(4))
set @Y=right(@Y,4)
set @M=cast(month(@Date) as varchar(3))
set @M='0'+@M
set @M=right(@M,2)
set @D=cast(day(@Date) as varchar(3))
set @D='0'+@D
set @D=right(@D,2)
set @YMD=@Y+@M+@D

begin transaction
set @num=cast(right(@regist,4) as int)
set @regist=SUBSTRING(@regist,1,8)

if @YMD=@regist
begin
set @num=@num+1
set @strNum=cast(@num as varchar(4))
set @strNum='000'+@strNum
set @strNum=right(@strNum,4)
set @weiyibiaoshi=@YMD+@strNum+''
end
else
begin
set @weiyibiaoshi=@YMD+'0001'
end

insert into test(regist_id,weiyibiaoshi,names,age,passwords) VALUES(@regist,@weiyibiaoshi,@name,@age,@password);


if @@error <> 0
begin
rollback transaction
return 0
end
else
begin
commit transaction
end
end
GO


{call insertTest('google','3','admin')}

有一張test表 欄位為：regist_id vachar,主鍵,weiyibiaoshi varchar,names varchar,age int,passwords varchar
