Symptom
• Unable to drop alias when no login record exists
• A check of the sysalternates table and user names shows that some orphaned aliases exist in the
database:
1> select suser_name(suid), * from sysalternates
2> go
suid altsuid
------------------------------ ----------- ----------myuser 7 1
NULL 366 1
• Attempt to remove the orphaned alias fails:
1> sp_dropalias NULL
2> go
Msg 17231, Level 16, State 1:
Server 'SYBASE', Procedure 'sp_dropalias', Line 176:
No login with the specified name exists.
Environment
SAP Adaptive Server Enterprise (ASE) 15.7
Cause
Discrepancies between the sysalternates table in a user database and the syslogins table in the master
database can occur when a user database is loaded from backups from a different ASE with varying values
in syslogins. In order to remove an alias from a user database, there must be a corresponding login account
for the suid in sysalternates.
Resolution
The supported method for cleaning up orphaned aliases in sysalternates is as follows:
1. Create a login account for the orphaned suid in sysalternates:

use master
go
create login dropme with password <xxx> suid 366
go
2. Drop the corresponding alias from the user database:
use mydb
go
sp_dropalias dropme
go
3. Drop the login account created in Step 1:
use master
go
drop login dropme with override
go
Note: In versions prior to ASE 15.7, use the system procedures sp_addlogin and sp_droplogin
instead of the CREATE/DROP LOGIN commands.
