刪除大量資料作法

Method 1

若刪除完成之後留下的資料較多的話(例如要刪除1/3的資料)，就用WHILE DELETE top語法來刪除

 declare @n int
 while 1=1
 begin
 DELETE top(2000)
 FROM dbo.BigTable
 WHERE time <= '2013-09-03 22:00:00.000'
 OPTION(MAXDOP 1) -- 可考慮是否只使用一個CPU來執行刪除動作
 set @n=@@ROWCOUNT
 if @n<2000
 break
 end

Method 2
若留下的資料比較少(例如要刪除2/3的資料或更多的資料)，就可以考慮INSERT INTO再TRUNCATE或INSERT INTO再RENAME

• INSERT INTO and TRUNCATE

1.將要保留的資料INSERT INTO到dbo.Temp_BigTable

SELECT * INTO dbo.Temp_BigTable
 FROM dbo.Temp_BigTable
 WHERE Date < '2015/1/1';

2.清空dbo.Temp_BigTable
 TRUNCATE TABLE dbo.Temp_BigTable;

3.INSERT INTO dbo.BigTable from dbo.Temp_BigTable
 INSERT INTO dbo.BigTable
 SELECT * FROM dbo.Temp_BigTable;

可以參考這篇 SQL Server: Delete a Huge Amount of Data from a Table

• INSERT INTO再RENAME

1.將要保留的資料INSERT INTO到dbo.Temp_BigTable
2.DROP TABLE dbo.Temp_BigTable
3.RENAME dbo.Temp_BigTable to dbo.BigTable

注意:
因為原Table會被刪除，所以需事先調查與保存與重新設定以下項目
1.權限
2.Trigger
3.Index

PS.以下狀況無法直接DROP TABLE
1.被Foreign Key或view with SCHEMABINDING reference的資料表
2.複寫發行資料表
3.啟用CDC的資料表

若有view with schemabinding

CREATE VIEW v_Table_2
WITH SCHEMABINDING

DROP TABLE會出現以下錯誤

Msg 3729, Level 16, State 1, Line 2
Cannot DROP TABLE ‘dbo.Table_1’ because it is being referenced by object ‘v_Table_2’.

若有Foreign key reference

DROP TABLE會出現以下錯誤

Msg 3726, Level 16, State 1, Line 2
Could not drop object ‘dbo.Table_1’ because it is referenced by a FOREIGN KEY constraint.

Rowset trace(Rowset Provider)

Server-Side Trace with file provider(File Provider)
如果是Server-Side Trace則是使用file provider

 select * from sys.traces where is_rowset = 0 and path is not NULL

PS. The file provider is designed with a guarantee that no event data will be lost.

Rowset Trace(Rowset Provider)
SQL Server Profiler連線到SQL Server啟動的就是Rowset Trace (使用rowset provider)

select * from sys.traces where is_rowset = 1 and path is NULL

PS. The rowset provider, on the other hand, is not designed to make any data loss guarantees.
If data is not being consumed quickly enough and its internal buffers fill, it waits up to 20 seconds before it begins jettisoning events in order to free buffers to get things moving. The SQL Server Profiler client tool will send a special error message if events are getting dropped, but you can also find out if you’re headed in that direction by monitoring SQL Server’s TRACEWRITE wait type, which is incremented as threads are waiting for buffers to free up.
SQL Server Profiler pulls these events from the rowset provider via a call to sp_trace_getdata and performs a “pivot” to produce the human-readable output we’re used to seeing. This is yet another reason that the rowset provider can be less efficient than the file provider—sending so many rows can produce a huge amount of network traffic.
If you do require rowset provider-like behavior for your monitoring needs, you luckily will not need to figure out how to manipulate this data. SQL Server 2005 ships with a series of managed classes in the Microsoft.SqlServer.Management.Trace namespace, designed to help with setting up and consuming rowset traces. The use of these classes is beyond the scope of this chapter, but they are well documented in the SQL Server TechCenter on TechNet, and readers should have no trouble figuring out how to exploit what they offer.

1.資料庫相容性層級影響基數估計(Cardinality Estimation)
提升資料庫相容性層級就可以改善效能

The New and Improved Cardinality Estimator in SQL Server 2014
https://blogs.technet.microsoft.com/dataplatforminsider/2014/03/17/the-new-and-improved-cardinality-estimator-in-sql-server-2014/
Cardinality Estimation (SQL Server)
https://msdn.microsoft.com/en-us/library/dn600374.aspx
CE(Cardinality Estimation)會預測您的查詢可能傳回的資料列數目。 查詢最佳化工具使用基數預測，來產生最佳查詢計劃。 CE 愈精確，查詢計劃通常愈理想。
In 1998, a major update of the CE was part of Microsoft SQL Server 7.0, for which the compatibility level was 70. Subsequent updates came with SQL Server 2014 and SQL Server 2016, meaning compatibility levels 120 and 130. The CE updates for levels 120 and 130 incorporate assumptions and algorithms that work well on modern data warehousing workloads and on OLTP (online transaction processing).
新版(層級 120 和 130 )的基數估計更新了合併假設與演算法，增強並適用於新式資料倉儲工作負載和 OLTP (線上交易處理)。

改善了以下的問題
Your application system could possibly have an important query whose plan is changed to a slower plan due to the new CE. Such a query might be like one of the following:

• An OLTP query that runs so frequently that multiple instance of it often run concurrently.
• A SELECT with substantial aggregation that runs during your OLTP business hours.

Database Corruption Challenge – Steve Stedman
Presented by Steve Stedman
https://www.youtube.com/watch?v=5oBA5nL0uRc&feature=youtu.be&a

1.備份資料庫，還原至測試機來進行修復工作(確保還原程序遭遇問題時，可以重頭再來修復一次)
2.如果決定用allow data loss，嘗試先找出可能遺失的資料並事先嘗試SELECT INTO保留下來
3.執行之前尋求是否有其他人的意見

定期執行

osql -E -Q"DBCC CHECKDB (AdventureWorks) WITH ALL_ERRORMSGS, NO_INFOMSGS" -oC:\outputfile.txt
sqlcmd -E -Q"DBCC CHECKDB (AdventureWorks) WITH ALL_ERRORMSGS, NO_INFOMSGS" -o C:\outputfile.txt

PS.WITH NO_INFOMSGS只顯示錯誤訊息，一般的information不顯示

基本流程

1.將有損毀的資料庫備份檔還原到測試機，切換成single_user mode。

ATLER DATABASE AdventureWorks SET SINGLE_USER WITH ROLLBACK_IMMEDIATELY;

2.取得錯誤訊

USE [master];
GO
DBCC CHECKDB (AdventureWorks) WITH NO_INFOMSGS;
GO

DBCC CHECKTABLE ('HumanResources.Employee') WITH NO_INFOMSGS;
GO

2.取回損毀的資料

(1)如果原資料表還能查詢的狀況

A.透過DBCC CHECKTABLE找出哪一筆或哪幾筆資料損毀

page(1, 280) ->page 280

DBCC TRACEON(3604)
DBCC PAGE(dbname, 1, 280,2) with no_infomsgs;
從結果找出m_type
m_type=1 ->data page
slotcount =27 -> number of rows in this page
所以如果執行allow data loss則會出現27然後修復完成(損毀的地方)

B.透過select with non-clustered Index取回一些資料。

select col1, col2 from table with (index=clusted_index1);

利用彙總函數，比對clustered index與non-clustered index資料是否有不同

PS.數值與日期欄位可用SUM(column)，文字欄位可用 SUM(LEN(column))

若查出來值不同(例如col4不同)，表示其中一個欄位有損毀

使用OUTER ALL JOIN 同一個TABLE 找出哪一筆的col4是NULL

因無法直接update or delete那一筆損毀的資料，若執行會出現錯誤

所以從non-cluster index SELECT資料到table_save暫存資料表

D.嘗試修復

DBCC CHECKTABLE(tableName, REPAIR_REBUILD)

通常無法修復

DBCC CHECKTABLE(tableName, REPAIR_ALLOW_DATA_LOSS)

出現找到錯誤，並已經修復
但執行select * from table發現只剩一半的資料，其他消失

E.將資料從table_save補回原資料表

接下就INSERT table select * from table_save
where table.id not in (select id from table)

(2)如果原資料表不能查詢的狀況

A.先透過select with non-clustered Index取回一些資料。(如果後面的步驟無法取得完整資料，最少還有這些)

B.嘗試透過DBCC IND, DBCC PAGE來取回損毀資料表(clustered index)的完整資料

C.再用TRUNCATE TABLE來移除損毀

D.INSERT SELECT from救回資料的資料表

3.修復資料庫並回存資料

truncate table Table_1
insert into Table_1 select * from Table_copy

PS C:\Temp>.\myPS.ps1

C:\Temp\myPS.ps1 檔案無法載入，因為這個系統上已停用指令碼執行。如需詳細資訊，請參閱 “get-help about_signing”。

SQL Server Physical Join (Nested Loops joins, Merge joins, Hash joins)

Advanced Query Tuning Concepts
https://technet.microsoft.com/en-us/library/ms191426(v=sql.105).aspx

SQL Server employs three types of join operations:

• Nested loops joins
• Merge joins
• Hash joins

Nest Loops Joins

If one join input is small (fewer than 10 rows) and the other join input is fairly large and indexed on its join columns, an index nested loops join is the fastest join operation because they require the least I/O and the fewest comparisons. For more information about nested loops, see Understanding Nested Loops Joins.

Merge Joins

If the two join inputs are not small but are sorted on their join column (for example, if they were obtained by scanning sorted indexes), a merge join is the fastest join operation. If both join inputs are large and the two inputs are of similar sizes, a merge join with prior sorting and a hash join offer similar performance. However, hash join operations are often much faster if the two input sizes differ significantly from each other. For more information, see Understanding Merge Joins.

Hash Joins

Hash joins can efficiently process large, unsorted, nonindexed inputs. They are useful for intermediate results in complex queries because:

• Intermediate results are not indexed (unless explicitly saved to disk and then indexed) and often are not suitably sorted for the next operation in the query plan.
• Query optimizers estimate only intermediate result sizes. Because estimates can be very inaccurate for complex queries, algorithms to process intermediate results not only must be efficient, but also must degrade gracefully if an intermediate result turns out to be much larger than anticipated.

The hash join allows reductions in the use of denormalization. Denormalization is typically used to achieve better performance by reducing join operations, in spite of the dangers of redundancy, such as inconsistent updates. Hash joins reduce the need to denormalize. Hash joins allow vertical partitioning (representing groups of columns from a single table in separate files or indexes) to become a viable option for physical database design. For more information, see Understanding Hash Joins.

How to reset forgotten sa password

如何重設sa密碼  或 忘記sa密碼的情況下加入一個SQL管理員帳戶

如果忘記sa密碼，有2個方法解決

方法一

不需要重啟SQL Server服務，但Login裡面必須要原本就有NT AUTHORITY\SYSTEM帳戶，且此帳戶要有sysadmin Role

1.下載Sysinternals的psexec.exe工具

https://technet.microsoft.com/en-us/sysinternals/bb897553.aspx

2.啟動命令提示字元，用psexec.exe來啟動SSMS，就可以用NT SERVICE\SYSTEM身分Windows驗證登入

PsExec.exe -s -i "C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe"

SQL Server Managment Studio default locations

方法二

處理過程會有downtime，因為需重新啟動SQL Server服務。

1.停止SQL Server服務

2.啟動第1個命令提示字元，以Single user mode啟動SQL Server

Start the SQL Server instance using single user mode (or minimal configuration which will also put SQL Server in single user mode)

SQLServr.Exe –m (or SQLServr.exe –f)

for exsample:

3.在SQL Server本機，啟動第2個命令提示字元，使用sqlcmd用Windows驗證直接登入

SQLCMD –S <Server_Name\Instance_Name>

4.建立一個新Login並給予sysadmin role

create a new account or add an existing login to SYSADMIN server role

CREATE LOGIN [dbasa] with
PASSWORD= N'dbasa_P@ssw0rd',
CHECK_POLICY = OFF
GO
sp_addsrvrolemember 'dbasa', 'SYSADMIN'
GO

5.使用Ctrl+C來第1個命令提示字元的sql server

6.正常啟動SQL Server，就可以用剛剛建立的dbasa管理員帳戶登入，接下來如果需要，就去改掉sa密碼。
