关于sqlserver中触发器的问题

想写一个触发器，在userinfo表里新增数据，当新增数量为10时，再把这10条数据批量插入temp表中，请问怎么实现，我写的这个实现不了
create trigger trigger_mq
on userInfo

for insert

as
if ((select count(*) as num from inserted)=10)
begin
insert into temp(name,age) select name,age from inserted
end
go

create trigger trigger_mq
on userInfo
for insert
as 
    begin
        declare @param int 
        set @param=select count(*) from inserted
        if (@param=10)
        begin
            insert into temp(name,age) select name,age from inserted
        end
    end
go
