Question

When I try to install tSQLt onto an existing database i get the following error:

The database owner SID recorded in the master database differs from
the database owner SID recorded in database ”. You should correct
this situation by resetting the owner of database ” using the ALTER
AUTHORIZATION statement.

Answer 1

This problem can arise when a database restored from a backup and the SID of the database owner does not match the owners SID listed in the master database. Here is a solution that uses the “ALTER AUTHORIZATION” statement recommended in the error message:

DECLARE @Command VARCHAR(MAX) = 'ALTER AUTHORIZATION ON DATABASE::[<<DatabaseName>>] TO 
[<<LoginName>>]' 

SELECT @Command = REPLACE(REPLACE(@Command 
            , '<<DatabaseName>>', SD.Name)
            , '<<LoginName>>', SL.Name)
FROM master..sysdatabases SD 
JOIN master..syslogins SL ON  SD.SID = SL.SID
WHERE  SD.Name = DB_NAME()

PRINT @Command
EXEC(@Command)
