If a system procedure is executed in a database other than sybsystemprocs, it operates on the system tables in the database in which it was executed. For example, if the Database Owner of pubs2 runs sp_adduser in pubs2, the new user is added to pubs2..sysusers.
To run a system procedure in a specific database, either:
Open that database with the use command and execute the procedure, or
Qualify the procedure name with the database name.
For example, the user-defined system procedure sp_foo, which executes the db_name system function, returns the name of the database in which it is executed. When executed in the pubs2 database, it returns the value “pubs2”:
exec pubs2..sp_foo
------------------------------ pubs2
(1 row affected, return status = 0)
When executed in sybsystemprocs, it returns the value “sybsystemprocs”:
exec sybsystemprocs..sp_foo
------------------------------ sybsystemprocs
(1 row affected, return status = 0)
