SQL Server数据库常用近百条SQL语句分享

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.backupset
dbo.log_shipping_secondary
dbo.restorehistory
dbo.sysjobs
dbo.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_who 
sp_who2 
sp_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

select DB_NAME(dbid),* from sys.sysprocesses where dbid=db_id(\'dbname\')

21. 查询当前阻塞的所有请求

select * from sys.sysprocesses where blocked>0
或
SELECT t1.resource_type,db_name(t1.resource_database_id),t1.resource_associated_entity_id,t1.request_mode,
t1.request_session_id,t2.blocking_session_id,t2.wait_duration_ms
FROM sys.dm_tran_locks as t1
INNER JOIN sys.dm_os_waiting_tasks as t2
ON t1.lock_owner_address = t2.resource_address;
或
select A.SPID as 被阻塞进程,a.CMD AS 正在执行的操作,b.spid AS 阻塞进程号,b.cmd AS 阻塞进程正在执行的操作
from master..sysprocesses a,master..sysprocesses b
where a.blocked<>0 and a.blocked= b.spid
或
SELECT session_Id,spid,ecid,DB_NAME (sp.dbid),nt_username,er.status,wait_type,
[Individual Query] =SUBSTRING (qt.text,er.statement_start_offset / 2,
( CASE
WHEN er.statement_end_offset = -1
THEN
LEN (CONVERT (NVARCHAR (MAX), qt.text)) * 2
ELSE
er.statement_end_offset
END
- er.statement_start_offset)
/ 2),
qt.text,program_name,Hostname,nt_domain,start_time
FROM sys.dm_exec_requests er
INNER JOIN sys.sysprocesses sp ON er.session_id = sp.spid
CROSS APPLY sys.dm_exec_sql_text (er.sql_handle) AS qt
WHERE session_Id > 50 /* Ignore system spids.*/
AND sp.blocked>0 AND session_Id NOT IN (@@SPID)
或
SELECT session_id ,status ,blocking_session_id
,wait_type ,wait_time ,wait_resource
,transaction_id
FROM sys.dm_exec_requests
WHERE status = N\'suspended\';
--sys.dm_exec_requests返回SQL Server 中正在执行的每个请求的信息

22. 查看哪些表被锁了，以及这些表被哪个进程锁了

select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks where resource_type=\'OBJECT\' ORDER BY request_session_id ASC

23. 查询某个job是否被堵塞

select * from msdb.dbo.sysjobs where name=\'jobname\'
select a.program_name,a.* from master..sysprocesses a where a.program_name like \'%0D1CE57E8AC5%\'
--把第一个语句查询到的job_id代入第二个语句的program_name

24. 检查SQL Agent是否开启

IF EXISTS (
SELECT TOP 1 1
FROM sys.sysprocesses
WHERE program_name = \'SQLAgent - Generic Refresher\'
)
SELECT \'Running\'
ELSE
SELECT \'Not Running\'

25. 查看活动线程执行的sql语句,并生成批量杀掉的语句

select \'KILL \' CAST(a.spid AS NVARCHAR(100)) AS KillCmd,REPLACE(hostname,\' \',\'\') as hostname ,replace(program_name,\' \',\'\') as program_name
