sql server常用语句
1. sqlserver查看实例级别的信息，使用SERVERPROPERTY函数select
SERVERPROPERTY ('propertyname')2. 查看实例级别的某个参数XX的配置
select *
from
sys.configurations
where
name='XX' 3. 更改实例级别的某个参数XX的值
sp_configure 'XX' ,'0' RECONFIGURE WITH OVERRIDE
sp_configure显示或更改当前服务器的全局配置设置。
RECONFIGURE表示SQL Server不用重新启动就立即生效 。
使用sp_configure更改设置时，请使用RECONFIGURE语句使更改立即生效，否则更改将在SQL Server重新启动后生效。RECONFIGURE后面加WITH OVERRIDE表示不管这个值是不是符合要求都会生效，比如recovery interval的范围值是10--60对应sys.configurations.minimum是10、sys.configurations.maximum是60，如果sp_configure 'recovery interval', 75设置为75，超过了这个10--60规范，但是要让75生效，则必须加上WITH OVERRIDE。
4. sqlserver没有系统表可以查询所有数据库下面对象，以下只能在当前数据库下面查
select *
from
sys.all_objects
--查询当前数据库的所有架构范围的对象
select * from sys.sysobjects
--查询当前数据库的所有对象
--sys.all_objects、sys.sysobjects 这种的视图，在每个数据库的系统视图下面都有
select *
from
sys.databases
--在当前数据库下可以查询到所有数据库信息，包含是否on状态select * from sys.sysdatabases
--在当前数据库下可以查询到所有数据库信息，不包含是否on状态，这个系统视图会在后续的版本中删除
--sys.databases、sys.sysdatabases这种的视图，在每个数据库的系统视图下面都有sys.processes
--没有这个视图select * from sys.sysprocesses
--在当前数据库下可以查询所有正在SQL Server 实例上运行的进程的相关信息，也就是所有数据库上的线程，这个系统视图会在后续的版本中删除
5. 全局系统视图、单个数据库系统视图 sys.database_files --每个存储在数据库本身中的数据库文件在表中占用一行。这是一个基于每个数据库的视图。sys.master_files --master 数据库中的每个文件对应一行。这是一个系统范围视图。--sys.database_files、sys.master_files这种的视图，在每个数据库的系统视图下面都有
6. 一些只存在msdb的系统表，而非系统视图 dbo.backupsetdbo.log_shipping_secondarydbo.restorehistorydbo.sysjobsdbo.sysjobhistory--这些系统表只存在msdb数据库，使用的时候必须加上msdb前缀
7. sp_lock、sp_who、sp_who2、sp_helptext等一些系统存储过程存在于每个数据库中
8. 报告有关锁的信息，会显示实例里面的所有数据库的锁信息、堵塞信息 sp_lock
9. 提供有关当前用户、 会话和进程的实例中的信息，可以看到会话的状态running、SUSPENDED、sleeping、rollback，sp_who2通过CPUTime、DiskIO可以判断对应的transaction是否很大sp_whosp_who2sp_who2 active (可选参数LoginName, 或active代表活动会话数)CPUTime (进程占用的总CPU时间)DiskIO (进程对磁盘读的总次数)LastBatch (客户最后一次调用存储过程或者执行查询的时间)ProgramName (用来初始化连接的应用程序名称，或者主机名)
10. 查看某个存储过程的内容 sp_helptext pro_name
11.显示某个线程号发送到sqlserver数据库的最后一个语句 DBCC INPUTBUFFER
12.假设查询到249被锁给堵塞了，查询被堵塞的SQL语句 DBCC INPUTBUFFER (249)
13. 查看某个数据库中是否存在活动事务，有活动事务就一定会写日志 DBCC OPENTRAN (dbname)
14. 监视日志空间 DBCC SQLPERF (LOGSPACE)
15. 查找无法重用日志中的空间的原因(日志无法截断导致日志文件越来越大，但是可用空间很小，无法收缩)
select
name
, log_reuse_wait_desc
from
sys.databases
16. 查看虚拟日志文件信息 DBCC LOGINFO 结果有多少行，代表有多少虚拟日志文件，活动的虚拟日志文件的状态(status)为2
17. 修复msdb数据库，比如ssms页面sql server agent丢失或看不了job view history等功能，说明msdb坏了，需要修复 dbcc checkdb (msdb);
18. 在您当前连接到的 SQL Server 数据库中生成一个手动检查点 CHECKPOINT [ checkpoint_duration ]--checkpoint_duration表示以秒为单位指定手动检查点完成所需的时间，一般不使用这个参数，让数据库自己控制
19. 查看数据库各种设置
select
name
, State
, user_access
, is_read_only
, recovery_model
from
sys.databases
20. 查看某个数据库中是否存在会话

DB_NAME(dbid)
