/*
exec [les_AllowPaging] 15,100,' select * from sys.sysobjects '
exec [les_AllowPaging] 15,100,' select top 100 percent * from sys.sysobjects order by id'
ORDER BY 需要 percent
传入语句中存在分号需要先把传入语句格式化.
C# 例
string SqlStr = " select * from sys.sysobjects where name like ''"；
SqlStr=SqlStr.Replace("'", "$")；
