1. sql SERVER 2008 R2 怎麼輸入序列號
選擇開始菜單,在 Microsoft SQL Server 2008 R2 菜單下,選擇 配置工具 , 選擇 SQL Server 安裝中心(64位)。打開安裝中心後,在左邊菜單選擇 維護 , 然後選擇第一項 版本升級, 然後根據向導,在輸入序列號頁面輸入新的序列號,根據向導下一步,選擇升級的實例,就可以完成更改序列號的過程了。
在安裝的過程中,有一個界面,要求輸入序列號的。如果整個安裝過程沒有要求,可能你的軟體授權是不需要輸入序列號的那種。
2. SQL Server 2008怎樣添加自增列實現自增序號
Altertabletablename
addrec_idintIDENTITY(1,1)NOTFORREPLICATIONNOTNULL
上面是SQL Server 2008的新增語句
tablename 表名
rec_id 新增列名
IDENTITY(1,1) 自增序號從1開始,每次加1
解釋的應該很清楚了吧
3. sql server 2008 請教怎樣生成序列號
你這是什麼資料庫? SQL Server 的話,你可以把CID設為自增加1,這樣就可以實現在插入的時候自動生成CID的值了; 如果是oracle,你可以在oracle資料庫里建個sequense,通過 select sequense.next() from al 得到自增的序列號;
4. sql 2008和sql 2012的區別
sql 2008和sql 2012的區別為:版本不同、數據壓縮不同、加密不同。
一、版本不同
1、sql 2008:sql 2008包含企業版(Enterprise)、標准版(Standard)、專業版(Developer)。
2、sql 2012:sql 2012包含企業版(Enterprise)、標准版(Standard)、專業版(Developer)、商業智能版(Business Intelligence)。
二、數據壓縮不同
1、sql 2008:sql 2008沒有數據壓縮,基於策略的管理和集成全文檢索功能。。
2、sql 2012:sql 2012具有數據壓縮,基於策略的管理和集成全文檢索功能。
三、加密不同
1、sql 2008:sql 2008需要改動應用程序對整個資料庫、數據文件和日誌文件進行加密。
2、sql 2012:sql 2012可以對整個資料庫、數據文件和日誌文件進行加密,而不需要改動應用程序。
5. sqlserver2008不支持json
sql server2008支持json函數
1。json 轉化成數據集合

2.舉例
Select * from parseJSON('{
"聯系人":
{
"姓名": "huang",
"網名": "HTL",
"AGE": 05,
"男人":true,
"PhoneNumbers":
{
"mobile":"135123100514",
"phone":"0251-123456789"
}
}
}
')

二、sql轉化成json、xml等方法

三、sqlserver2016支持json
請看:https://msdn.microsoft.com/en-us/library/dn921897.aspx
SELECT Name, Surname,
JSON_VALUE(jsonCol, '$.info.address.PostCode') as PostCode,
JSON_VALUE(jsonCol, '$.info.address."Address Line 1"') + ' ' + JSON_VALUE(jsonCol, '$.info.address."Address Line 2"') AS Address,
JSON_QUERY(jsonCol, '$.info.skills') as Skills
FROM PeopleCollection
WHERE ISJSON(jsonCol) > 0
AND JSON_VALUE(jsonCol, '$.info.address.town') = 'Belgrade'
AND Status = 'Active'
ORDER BY JSON_VALUE(@jsonInfo, '$.info.address.PostCode')
