SQL Server 常用SQL語句（收藏版）

1. sqlserver查看實例級別的信息，使用SERVERPROPERTY函數

select SERVERPROPERTY ('propertyname')

2. 查看實例級別的某個參數XX的配置

select * from sys.configurations where name='XX'

3. 更改實例級別的某個參數XX的值

sp_configure 'XX','0' 
RECONFIGURE WITH OVERRIDE

sp_configure顯示或更改當前服務器的全局配置設置。

RECONFIGURE表示SQL Server不用重新啓動就立即生效 。

使用sp_configure更改設置時，請使用RECONFIGURE語句使更改立即生效，否則更改將在SQL Server重新啓動後生效。RECONFIGURE後面加WITH OVERRIDE表示不管這個值是不是符合要求都會生效，比如recovery interval的範圍值是10--60對應
sys.configurations.minimum是10、
sys.configurations.maximum是60，如果sp_configure 'recovery interval', 75設置爲75，超過了這個10--60規範，但是要讓75生效，則必須加上WITH OVERRIDE。

4. sqlserver沒有系統表可以查詢所有數據庫下面對象，以下只能在當前數據庫下面查

select * from sys.all_objects --查詢當前數據庫的所有架構範圍的對象
select * from sys.sysobjects --查詢當前數據庫的所有對象
--sys.all_objects、sys.sysobjects 這種的視圖，在每個數據庫的系統視圖下面都有
select * from sys.databases --在當前數據庫下可以查詢到所有數據庫信息，包含是否on狀態
select * from sys.sysdatabases --在當前數據庫下可以查詢到所有數據庫信息，不包含是否on狀態，這個系統視圖會在後續的版本中刪除
--sys.databases、sys.sysdatabases這種的視圖，在每個數據庫的系統視圖下面都有
sys.processes --沒有這個視圖
select * from sys.sysprocesses --在當前數據庫下可以查詢所有正在SQL Server 實例上運行的進程的相關信息，也就是所有數據庫上的線程，這個系統視圖會在後續的版本中刪除

5. 全局系統視圖、單個數據庫系統視圖

sys.database_files --每個存儲在數據庫本身中的數據庫文件在表中佔用一行。這是一個基於每個數據庫的視圖。
sys.master_files --master 數據庫中的每個文件對應一行。這是一個系統範圍視圖。
--sys.database_files、sys.master_files這種的視圖，在每個數據庫的系統視圖下面都有

6. 一些只存在msdb的系統表，而非系統視圖

dbo.backupset
dbo.log_shipping_secondary
dbo.restorehistory
dbo.sysjobs
dbo.sysjobhistory
--這些系統表只存在msdb數據庫，使用的時候必須加上msdb前綴

7. sp_lock、sp_who、sp_who2、sp_helptext等一些系統存儲過程存在於每個數據庫中

8. 報告有關鎖的信息，會顯示實例裏面的所有數據庫的鎖信息、堵塞信息

sp_lock

9. 提供有關當前用戶、 會話和進程的實例中的信息，可以看到會話的狀態running、SUSPENDED、sleeping、rollback，sp_who2通過CPUTime、DiskIO可以判斷對應的transaction是否很大

sp_who 
sp_who2 
sp_who2 active (可選參數LoginName, 或active代表活動會話數) 
CPUTime (進程佔用的總CPU時間) 
DiskIO (進程對磁盤讀的總次數) 
LastBatch (客戶最後一次調用存儲過程或者執行查詢的時間) 
ProgramName (用來初始化連接的應用程序名稱，或者主機名)

10. 查看某個存儲過程的內容

sp_helptext pro_name

11.顯示某個線程號發送到sqlserver數據庫的最後一個語句

DBCC INPUTBUFFER

12.假設查詢到249被鎖給堵塞了，查詢被堵塞的SQL語句

DBCC INPUTBUFFER (249)

13. 查看某個數據庫中是否存在活動事務，有活動事務就一定會寫日誌

DBCC OPENTRAN (dbname)

14. 監視日誌空間

DBCC SQLPERF (LOGSPACE)

15. 查找無法重用日誌中的空間的原因(日誌無法截斷導致日誌文件越來越大，但是可用空間很小，無法收縮)

select name,log_reuse_wait_desc from sys.databases

16. 查看虛擬日誌文件信息

DBCC LOGINFO

結果有多少行，代表有多少虛擬日誌文件，活動的虛擬日誌文件的狀態(status)爲2

17. 修復msdb數據庫，比如ssms頁面sql server agent丟失或看不了job view history等功能，說明msdb壞了，需要修復

dbcc checkdb (msdb);

18. 在您當前連接到的 SQL Server 數據庫中生成一個手動檢查點

CHECKPOINT [ checkpoint_duration ]
--checkpoint_duration表示以秒爲單位指定手動檢查點完成所需的時間，一般不使用這個參數，讓數據庫自己控制

19. 查看數據庫各種設置

select name,State,user_access,is_read_only,recovery_model from sys.databases

20. 查看某個數據庫中是否存在會話

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

21. 查詢當前阻塞的所有請求

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

( 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),

FROM sys.dm_exec_requests er
INNER JOIN sys.sysprocesses sp ON er.session_id = sp.spid

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 中正在執行的每個請求的信息

22. 查看哪些表被鎖了，以及這些表被哪個進程鎖了

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. 查詢某個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%'
--把第一個語句查詢到的job_id代入第二個語句的program_name

24. 檢查SQL Agent是否開啓

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

25. 查看活動線程執行的sql語句,並生成批量殺掉的語句
