Database is Recovery Pending in sql server

If the Database LOG file is  missing in SQL Server then Database is going to be RECOVERY PENDING mode.

First run the sql statement below check to find the name of the database with status

ALTER DATABASE [AdventureWorks] SET MULTI_USER

Msg 5120, Level 16, State 101, Line 24

Unable to open the physical file "D:\MSSQL\DATA\AdventureWorks_log.ldf". Operating system error 2: "2(The system cannot find the file specified.)".

Msg 5181, Level 16, State 5, Line 24

Could not restart database "AdventureWorks". Reverting to the previous status.

Msg 5069, Level 16, State 1, Line 24

ALTER DATABASE statement failed.

-- Database LOG file is  missing

AdventureWorks_log D:\MSSQL\DATA\AdventureWorks_log.ldf

Use master

go

ALTER DATABASE [AdventureWorks] REBUILD LOG ON(

NAME ='AdventureWorks_log' ,

FILENAME='D:\MSSQL\DATA\AdventureWorks_log.LDF' )

Warning: The log for database 'AdventureWorks' has been rebuilt. Transactional consistency has been lost. The RESTORE chain was broken, and the server no longer has context on the previous log files, so you will need to know what they were. You should run DBCC CHECKDB to validate physical consistency. The database has been put in dbo-only mode. When you are ready to make the database available for use, you will need to reset database options and delete any extra log files.

-- Now Database is in Restricted_user mode change to Multiuser

ALTER DATABASE [AdventureWorks] SET MULTI_USER

Database Security is most important to every organisation with any elevated access should be disabled to product the database. 

Below script is quick check to understand the User and its database roles in specific database. Make sure to grant or revoke  appropriate database level access to end users/Group. Keep checking/auditing the role regularly.

USE [Your Database];

SELECT u.[name] AS [UserName], r.[name] AS RoleName 

FROM sys.database_principals u 

JOIN sys.database_role_members drm ON u.principal_id = drm.member_principal_id 

JOIN sys.database_principals r ON drm.role_principal_id = r.principal_id

where  u.[name] = 'dbo'  OR  u.[name] = 'db_owner'

Data Read Access to All the users in the specific database after refresh

 After you refresh database from Production to UAT environments make sure to run below scripts to drop production users first then grant data read access to UAT users.

use [Database_Name]
go

select  'DROP USER' , '['+ name+']'  

from dbo.sysusers

where name LIKE '%PRD-%' 

GO

use [Database_Name]
go
select 'EXEC sys.sp_addrolemember '   ,   ''' db_datareader '''   ,   '['+ name+']'
