1. sqlserver檢視例項級別的資訊，使用SERVERPROPERTY函式

select SERVERPROPERTY ('propertyname')

2. 檢視例項級別的某個引數XX的配置

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

3. 更改例項級別的某個引數XX的值

sp_configure 'XX','0'

RECONFIGURE WITH OVERRIDE

sp_configure顯示或更改當前伺服器的全域性配置設定。

RECONFIGURE表示SQL Server不用重新啟動就立即生效 。

使用sp_configure更改設定時，請使用RECONFIGURE語句使更改立即生效，否則更改將在SQL Server重新啟動後生效。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設定為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資料庫下面物件，以下只能在當前資料庫下面查

select * from sys.all_objects --查詢當前資料庫的所有架構範圍的物件

select * from sys.sysobjects --查詢當前資料庫的所有物件

--sys.all_objects、sys.sysobjects 這種的檢視，在每個資料庫的系統檢視下面都有

select * from sys.databases --在當前資料庫下可以查詢到所有資料庫資訊，包含是否on狀態

select * from sys.sysdatabases --在當前資料庫下可以查詢到所有資料庫資訊，不包含是否on狀態，這個系統檢視會在後續的版本中刪除

--sys.databases、sys.sysdatabases這種的檢視，在每個資料庫的系統檢視下面都有

sys.processes --沒有這個檢視

select * from sys.sysprocesses --在當前資料庫下可以查詢所有正在SQL Server 例項上執行的程序的相關資訊，也就是所有資料庫上的執行緒，這個系統檢視會在後續的版本中刪除

5. 全域性系統檢視、單個數據庫系統檢視

sys.database_files --每個儲存在資料庫本身中的資料庫檔案在表中佔用一行。這是一個基於每個資料庫的檢視。

sys.master_files --master 資料庫中的每個檔案對應一行。這是一個系統範圍檢視。

--sys.database_files、sys.master_files這種的檢視，在每個資料庫的系統檢視下面都有

6. 一些只存在msdb的系統表，而非系統檢視

dbo.backupset

dbo.log_shipping_secondary

dbo.restorehistory

dbo.sysjobs

dbo.sysjobhistory

--這些系統表只存在msdb資料庫，使用的時候必須加上msdb字首

7. sp_lock、sp_who、sp_who2、sp_helptext等一些系統儲存過程存在於每個資料庫中

8. 報告有關鎖的資訊，會顯示例項裡面的所有資料庫的鎖資訊、堵塞資訊

sp_lock

9. 提供有關當前使用者、 會話和程序的例項中的資訊，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 (可選引數LoginName, 或active代表活動會話數)

CPUTime (程序佔用的總CPU時間)

DiskIO (程序對磁碟讀的總次數)

LastBatch (客戶最後一次呼叫儲存過程或者執行查詢的時間)

ProgramName (用來初始化連線的應用程式名稱，或者主機名)

10. 檢視某個儲存過程的內容

sp_helptext pro_name

11.顯示某個執行緒號傳送到sqlserver資料庫的最後一個語句

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. 檢視某個資料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. 查詢無法重用日誌中的空間的原因(日誌無法截斷導致日誌檔案越來越大，但是可用空間很小，無法收縮)

select name,log_reuse_wait_desc from sys.databases

16. 檢視虛擬日誌檔案資訊

DBCC LOGINFO

結果有多少行，代表有多少虛擬日誌檔案，活動的虛擬日誌檔案的狀態(status)為2

17. 修復msdb資料庫，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. 在您當前連線到的 SQL Server 資料庫中生成一個手動檢查點

CHECKPOINT [ checkpoint_duration ]

--checkpoint_duration表示以秒為單位指定手動檢查點完成所需的時間，一般不使用這個引數，讓資料庫自己控制

19. 檢視資料庫各種設定

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

20. 檢視某個資料庫中是否存在會話

69. 查詢分割槽函式

select * from sys.partition_functions

70. 檢視分割槽架構

select * from sys.partition_schemes

71. 查詢ssis包的資訊

select * from msdb.dbo.sysssispackages

72. 查詢某張表裡的索引的大小,如下示例表為dbo.table1

SELECT

i.name AS IndexName,

SUM(page_count * 8) AS IndexSizeKB

FROM sys.dm_db_index_physical_stats(

db_id(), object_id('dbo.table1'), NULL, NULL, 'DETAILED') AS s

JOIN sys.indexes AS i

ON s.[object_id] = i.[object_id] AND s.index_id = i.index_id

GROUP BY i.name

ORDER BY i.name

73. 重建表上的所有索引

alter index all on table_name rebuild with (online=on)

重建表上的某個索引

alter index index_name on table_name rebuild with (online=on)

重新組織表上的所有索引

alter index all on table_name reorganize

74. 檢視資料檔案可收縮空間，結果見Availabesize_MB欄位值

select name ,size*8/1024 as Totalsize_MB ,CAST(FILEPROPERTY(name,'SpaceUsed') AS int)*8/1024 as Usedsize_MB,

size*8/1024 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS int)*8/1024 AS Availabesize_MB

from sys.master_files where database_id=db_id(N'DBNAME')

75. 查詢某個表中的全部索引的資訊

declare @tableName varchar(50) = 'LbaListAlertDetail'

FROM sys.indexes IX

INNER JOIN sys.dm_db_index_usage_stats IXUS ON IXUS.index_id = IX.index_id AND IXUS.OBJECT_ID = IX.OBJECT_ID

INNER JOIN sys.dm_db_partition_stats PS on PS.object_id=IX.object_id

WHERE OBJECTPROPERTY(IX.OBJECT_ID,'IsUserTable') = 1

and IX.OBJECT_ID = @tableId

GROUP BY OBJECT_NAME(IX.OBJECT_ID) ,IX.name ,IX.type_desc ,IXUS.user_seeks ,IXUS.user_scans ,IXUS.user_lookups,IXUS.user_updates ,IXUS.last_user_seek ,IXUS.last_user_scan ,IXUS.last_user_lookup ,IXUS.last_user_update

sqlserver中類似oracle的dba_source的檢視是sys.sql_modules

76. 查詢某個資料庫下的表資料佔用磁碟容量最大的10張表

use XX

if exists(select 1 from tempdb..sysobjects where id=object_id('tempdb..#tabName') and xtype='u')

drop table #tabName

go

create table #tabName(

table_name varchar(100),

rowsNum varchar(100),

reserved_size varchar(100),

data_size varchar(100),

index_size varchar(100),

unused_size varchar(100)

)

declare @name varchar(100)

declare cur cursor for

select name from sysobjects where xtype='u' order by name

open cur

fetch next from cur into @name

while @@fetch_status=0

begin

insert into #tabName

exec sp_spaceused @name

fetch next from cur into @name

end

close cur

deallocate cur

select top 10 table_name, data_size,rowsNum ,index_size,unused_size ,reserved_size,convert(int,SUBSTRING(data_size,0,LEN(data_size)-2)) size

from #tabName ORDER BY size desc

或

select top 10 a.tablename,a.SCHEMANAME,sum(a.TotalSpaceMB) TotalSpaceMB,sum(a.RowCounts) RowCounts

from (

SELECT

t.NAME AS TableName,

s.Name AS SchemaName,

p.rows AS RowCounts,

SUM(a.total_pages) * 8 AS TotalSpaceKB,

CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB,

SUM(a.used_pages) * 8 AS UsedSpaceKB,

CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB,

(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB,

CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB

FROM

sys.tables t

INNER JOIN

sys.indexes i ON t.OBJECT_ID = i.object_id

INNER JOIN

sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id

INNER JOIN

sys.allocation_units a ON p.partition_id = a.container_id

LEFT OUTER JOIN

sys.schemas s ON t.schema_id = s.schema_id

WHERE

t.NAME NOT LIKE 'dt%'

AND t.is_ms_shipped = 0

AND i.OBJECT_ID > 255

GROUP BY

t.Name, s.Name, p.Rows) a

GROUP BY a.tablename,a.SCHEMANAME

order by sum(a.TotalSpaceMB) desc

--這個比上一個專業

77. 查詢某個資料庫中是否有create index '+name+ CHAR(10)

select 'use '+name+ CHAR(10) +'select DB_NAME(),OBJECT_NAME(OBJECT_ID),definition from '+name+'.sys.sql_modules

WHERE objectproperty(OBJECT_ID, ''IsProcedure'') = 1

AND definition like ''%online%=%on%'' and definition like ''%index%''' from sys.databases;

78. 根據id號查詢某個資料庫名

SELECT DB_NAME(18)

根據id號查詢某個物件名

SELECT OBJECT_NAME(1769220894)

79. 檢視收縮的進度100%，此語句要到指定的資料庫下執行

SELECT DB_NAME(database_id) AS Exec_DB

,percent_complete

,CASE WHEN estimated_completion_time < 36000000

THEN '0' ELSE '' END + RTRIM(estimated_completion_time/1000/3600)

+ ':' + RIGHT('0' + RTRIM((estimated_completion_time/1000)%3600/60), 2)

+ ':' + RIGHT('0' + RTRIM((estimated_completion_time/1000)%60), 2) AS [Time Remaining]

,b.text as tsql

,*

FROM SYS.DM_EXEC_REQUESTS

cross apply sys.dm_exec_sql_text(sql_handle) as b

WHERE command LIKE 'DbccFilesCompact%' --and database_id=db_id('cardorder')

ORDER BY 2 DESC

80. 檢視重新組織索引的100%進度

SELECT DB_NAME(database_id) AS Exec_DB

,percent_complete

,CASE WHEN estimated_completion_time < 36000000

THEN '0' ELSE '' END + RTRIM(estimated_completion_time/1000/3600)

+ ':' + RIGHT('0' + RTRIM((estimated_completion_time/1000)%3600/60), 2)

+ ':' + RIGHT('0' + RTRIM((estimated_completion_time/1000)%60), 2) AS [Time Remaining]

,b.text as tsql

,*

FROM SYS.DM_EXEC_REQUESTS

cross apply sys.dm_exec_sql_text(sql_handle) as b

WHERE command LIKE '%REORGANIZE%' --and database_id=db_id('cardorder')

ORDER BY 2 DESC

81. 檢視儲存過程的執行計劃

SELECT

d.object_id ,

DB_NAME(d.database_id) DBName ,

OBJECT_NAME(object_id, database_id) 'SPName' ,

d.cached_time ,

d.last_execution_time ,

d.total_elapsed_time/1000000 AS total_elapsed_time,

d.total_elapsed_time / d.execution_count/1000000

AS [avg_elapsed_time] ,

d.last_elapsed_time/1000000 AS last_elapsed_time,

d.execution_count ,

d.total_physical_reads ,

d.last_physical_reads ,

d.total_logical_writes ,

d.last_logical_reads ,

et.text SQLText ,

eqp.query_plan executionplan

FROM sys.dm_exec_procedure_stats AS d

CROSS APPLY sys.dm_exec_sql_text(d.sql_handle) et

CROSS APPLY sys.dm_exec_query_plan(d.plan_handle) eqp

WHERE OBJECT_NAME(object_id, database_id) = 'xxxx'

ORDER BY [total_worker_time] DESC;

82. 檢視當前使用者

select system_user

83. 查詢ddl修改操作的記錄

-執行如下找到trace檔案的目錄和名稱

select * from Sys.traces

-使用sqlserver profiler工具開啟trace檔案，就可以查到相關記錄
