Where is sysxlogins in Management Studio?

During the script processing I have this error:

"Supplied parameter s开发者_如何学运维id is in use."

I've heard that all logins and passwords are stored in sysxlogins table, where can I find it?

If you are asking about ms sql server then its in master database. Actually its not table but view and its calles sys.syslogins

Have a look at sys.sql_logins and sys.server_principals.
