这句取的是当前返回记录的总数，当然跟@PageSize一样啦。其实这段存储过程是改编自：
http://www.cnblogs.com/tintown/archive/2005/04/24/144276.html
原来的代码中含有
@doCount bit = 0, -- 返回记录总数, 非 0 值则返回
这个输入参数，可以控制是否计算总数。if @doCount != 0
begin
if @strWhere !=''''
set @strSQL = "select count(*) as Total from [" + @tblName + "] where "+@strWhere
else
set @strSQL = "select count(*) as Total from [" + @tblName + "]"
end
--以上代码的意思是如果@doCount传递过来的不是0，就执行总数统计。最后计算总数输出为Total，在返回记录集中把total取出就行了。
