declare @P1 int, --P1是游标的id
@rowcount int
exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output
select ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页
set @currentpage=(@currentpage-1)*@pagesize+1
exec sp_cursorfetch @P1,16,@currentpage,@pagesize
exec sp_cursorclose @
