MSSQL數據庫遷移之用戶名問題
添加時間：2014-3-9 17:35:21
添加：
思海網絡
用戶A存在于數據庫A中，而新的MSSQL中雖然能創建用戶A，但無法把權限賦于用戶A。新創建一個用戶B吧，用戶A創建的表和其它信息就又無法訪問。在這里找到了解決方法：
在源 SQL Server 上運行以下腳本。此腳本可在 master 數據庫中創建名為 sp_hexadecimal 和 sp_help_revlogin 的兩個存儲過程。請在完成過程的創建之后繼續執行第 2 步。
注意：下面的過程取決于 SQL Server 系統表。這些表的結構在 SQL Server 的不同版本之間可能會有變化，請不要直接從系統表中選擇。
----- Begin , Create sp_help_revlogin procedure -----

2. 在創建 sp_help_revlogin 存儲過程后，請從源服務器上的查詢分析器中運行 sp_help_revlogin 過程。sp_help_revlogin 存儲過程可同時用于 SQL Server 7.0 和 SQL Server 2000。sp_help_revlogin 存儲過程的輸出是登錄腳本，該腳本可創建帶有原始 SID 和密碼的登錄。保存輸出，然后將其粘貼到目標 SQL Server 上的查詢分析器中，并運行它。例如：EXEC master..sp_help_revlogin
第1步后，在源服務器上運行sp_help_revlogin后，會產生創建用戶數據的SQL，例如：
/* sp_help_revlogin
** Generated 06 24 2009 1:40PM on WORKGROU-B1XTVC */
DECLARE @pwd sysname
-- Login: hxtest
SET @pwd = CONVERT (varbinary(256), 0x0100CF4E7D342B359438E4BCCA72E6C83F44FCCF30C8016286DE2B359438E4BCCA72E6C83F44FCCF30C8016286DE)
EXEC master..sp_addlogin '520web', @pwd, @sid = 0x1738BB6AD0CD24498F67FB5589E8EDCB, @encryptopt = 'skip_encryption'

把這段直接在新服務器上運行，或者找到相應的用戶名創建，就可以解決這個問題了!
