Question

We’ve got a database that was imported from another domain and when importing the bak file, the group from their domain was imported as well. And now I need to change this to the group that we have in our own domain. While preserving the permissions that are set.

I can see this when I right click the database and go to Properties and select Permissions. It says domain\groupname and I need to change this to ourdomain\groupname instead, while preserving the permissions that are set.

DECLARE @principal_id SMALLINT , @sql NVARCHAR(MAX) = N''

SELECT @principal_id = principal_id FROM sys.database_principals WHERE name = 'domain\groupnameOLD'

SELECT @sql  = @sql + state_desc+N' '+permission_name+N' ON ['+s.name+N'].['+o.name+N'] TO [domain\groupnameNEW];'+Nchar(13)+NCHAR(10)
FROM sys.database_permissions p
JOIN sys.objects o
    ON p.major_id = o.object_id
JOIN sys.schemas s
    ON o.schema_id = s.schema_id
WHERE 
    class = 1
AND grantee_principal_id = @principal_id
AND minor_id = 0
AND major_id > 0

PRINT @sql

you know what to do after
