This may be helpful if you have 2 enviroments and on each one of them
the object (db, table, stored-procedure) are diffrent,
so you can check whether this is the specific db and perform actions...
Check is Database exists:
if db_id('dbname') is not null
Check is Table exists:
if object_id('object_name', 'U') is not null -- for table
Check is Store-Procedure exists:
if object_id('object_name', 'P') is not null -- for SP
hope this is helps...
