sql2000数据库同步，写的存储过程循环不运行。请高手帮忙看看!!!
一个数据库是HWATT，从HWATT数据库把用户导入到kaoqin数据库中。
CREATE PROCEDURE INSERTUSER  AS
begin
declare @userid int
declare @username int
declare @count int
declare @userkaoname varchar
declare @sqlstr varchar
set @count = 0
select @count = count(*) from HWATT.dbo.KQZ_Employee where Birthday between dateadd(wk,datediff(wk,0,getdate()),0) and getdate()
while @count>0
begin
select @sqlstr = 'select top('+convert(varchar,@count)+')  '+convert(varchar,@userid)+' = EmployeeCode, '+convert(varchar,@userkaoname)+' = EmployeeName from HWATT.dbo.KQZ_Employee where Birthday between dateadd(wk,datediff(wk,0,getdate()),0) and getdate()'
exec (@sqlstr)
select @username = userid from userinfo where BADGENUMBER = @userid
if(@username<0)
begin
insert into USERINFO(BADGENUMBER,NAME,DEFAULTDEPTID,ATT,INLATE,OUTEARLY,OVERTIME,SEP,HOLIDAY,LUNCHDURATION,privilege,InheritDeptSch,InheritDeptSchClass,AutoSchPlan,MinAutoSchInterval,RegisterOT,InheritDeptRule,EMPRIVILEGE) VALUES(@userid,@userkaoname,'1','1','1','1','1','1','1','1','0','1','1','1','24','1','1','0')
set @count = convert(int,@count)-1
end
set @count = convert(int,@count)-1
end

	inner join userinfo b on a.EmployeeCode=b.BADGENUMBER  -->一定要用inner join 连接

		and not exists (select 1 from USERINFO c where a.EmployeeCode=c.BADGENUMBER)  -->加这一么判断过滤掉重复 

	select '运行成功'

end try

begin catch

	select '运行失败'

end catch
