sql中的游标

declare @id varchar(10)
declare @nm varchar(10)
declare @table as table(emp varchar(10),empname varchar(10))
declare CurEmp cursor for select top 6 empid,empname from employee

open CurEmp
fetch next from CurEmp into @id,@nm
While @@fetch_status=0
 begin
  insert @table(emp,empname) values(@id,@nm)
  fetch next from CurEmp into @id,@nm
 end
close CurEmp
deallocate CurEmp

select * from @table

 

如果需要从某一结果集中逐一地读取一条记录，可以用游标实现，上面是个简单的例子
