ORACLE中用rownum分页并排序的SQL语句
第一种：
select b.* from
( select a.*, rownum row_num from
(select t.* from A05_ORGANIZATION t order by org_name_en asc) a
) b
where b.row_num between 1 and 5 order by b.row_num asc
第二种（更高效）：
select b.* from
( select a.*, rownum row_num from
(select t.* from A05_ORGANIZATION t order by org_name_en asc) a
where rownum <=5
) b
where b.row_num >=1 order by b.row_num asc

SQl Xml和C# Xml数据的一点操作总结
在此申明Xml是InfoSet数据不是字符串，所以在此强烈反对用string拼接xml。数据库可以存放xml类型数据，那么该数据的具体操作又如何了。
1.首先建立一张含有xml数据类型的表
CREATE TABLE [dbo].[TestXml](
[ID] [bigint] IDENTITY(1,1) NOT NULL,
[Message] [xml] NULL ......
前面有TX留言问分页的sql是怎么样的，看完这篇你也就知道了。 组件可以输出执行的sql，方便查看sql生成的语句是否有问题。 通过注册事件来输出sql DbSession.Default.RegisterSqlLogger(database_OnLog);
private string sql;
void database_OnLog(string logMsg)
{
//保存执行的DbCommand (sql语 ......
