sqlServer：
一次查询，数据库只返回一页的数据。而不是取出所有的数据。
pagesize：每页显示记录数
cureentpage：当前页数
select * from (   select TOP pagesize * from ( SELECT TOP pagesize*cureentpage   * from my_table   ORDER BY id ASC ) as amyTable   ORDER BY id DESC ) as bmyTable   ORDER BY id ASC
假设共有有8条记录，每页显示3条记录，id 为3，6，7，37
第一页（首页）
select * from (   select TOP 3 * from ( SELECT TOP 3*1   * from my_table   ORDER BY id ASC ) as amyTable   ORDER BY id DESC ) as bmyTable   ORDER BY id ASC
第二页
select * from (   select TOP 3 * from ( SELECT TOP 3*2 * from my_table   ORDER BY id ASC ) as amyTable   ORDER BY id DESC ) as bmyTable   ORDER BY id ASC
第三页（尾页）
select * from (   select TOP 8-2*3 * from ( SELECT TOP 8-3*2&nbs ......

    当SQLServer的系统日志过大，就会引起SQLServer服务器无法启动等一系列问题。今天我遇到了这个问题，在网上搜索了一下，解决方法是删除就可以了，可是当前的ErrorLog正在被SQL使用无法删除啊，要删除只能停止SQL服务器，难道就没有别得办法了吗？
    回答是肯定的：使用以下存储过程：EXEC sp_cycle_errorlog
注释
每次启动 SQL Server 时，当前错误日志重新命名为 errorlog.1；errorlog.1 成为 errorlog.2，errorlog.2 成为 errorlog.3，依次类推。sp_cycle_errorlog 使您得以循环错误日志文件，而不必停止而后再启动服务器。

查看是否区分大小写-执行存储过程sys.sp_server_info
exec sys.sp_server_info
查看第18行COLLATION_SEQ-collation属性
charset=cp936 collation=Chinese_PRC_CS_AS
cs为区分大小写，CI为不区分大小写
将区分大小写改为不区分大小写
alter database yourDB COLLATE Chinese_PRC_CI_AS
将不区分大小写改为区分大小写
alter database yourDB COLLATE Chinese_PRC_CS_AS ......
