無法刪除作業，約束衝突，解決方案：
--開啟SQL查詢，
use msdb
select * from sysmaintplan_plans --檢視作業ID
delete from dbo.sysmaintplan_log where plan_id = 'C0A996D6-3A11-4E6C-A814-BB91B0ACBDAF'
delete from sysmaintplan_subplans where plan_id = 'C0A996D6-3A11-4E6C-A814-BB91B0ACBDAF'
DELETE FROM sysmaintplan_plans WHERE [ID]= 'C0A996D6-3A11-4E6C-A814-BB91B0ACBDAF'
--然後再到SQL SERVER 代理-----作業----即可刪除

建立查詢 , 提示目錄名無效

在目錄:C:\Documents and Settings\Administrator\Local Settings\Temp 下, 建立目錄名稱為1, 如果1存在建立目錄名稱為2.

MSSQL從TXT或CSV源還原資料

1、使用查詢語句獲取資料，例“SELECT * FROM [InformationSrv].[dbo].[Tb_PriceList] where PriceDate>='2021-08-01'”，查詢結果儲存成txt或csv格式檔案。
2、還原：DB-右鍵-匯入資料-選擇平面檔案源（高階-寬度500要選足夠）-選擇目標db-選擇源表和源檢視（編輯對映-勾選啟用標識插入）-開始執行

===============================================================

查詢附加資料庫的進度

EXEC sp_who2; #檢視程序相應的PID

SELECT

FROM sys.dm_exec_requests WHERE session_id=56
（最後的session_id修改成查詢到的PID，執行後process_percent、percent_complete值為進度百分比）

======================================================================

檢視被鎖表：
select request_session_id spid,OBJECT_NAME(resource_associated_entity_id) tableName
from sys.dm_tran_locks where resource_type='OBJECT'
(註釋：spid 鎖表程序 ，tableName 被鎖表名）

解鎖：
declare @spid int
Set @spid = 244 --鎖表程序spid
declare @sql varchar(1000)
set @sql='kill '+cast(@spid as varchar)
exec(@sql)

查詢程序資訊SPID等：
EXEC sp_who2;
========================================================================

檢視最慢的sql：
SELECT TOP 5 total_worker_time, last_worker_time,
max_worker_time, min_worker_time,
SUBSTRING(st.text, (qs.statement_start_offset/2) + 1,
((CASE statement_end_offset
WHEN -1 THEN DATALENGTH(st.text)
ELSE qs.statement_end_offset END
- qs.statement_start_offset)/2) + 1) as statement_text
FROM sys.dm_exec_query_stats as qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) as st
ORDER BY max_worker_time DESC
