I'm having some friction when it comes to showplan permission security.
Say there are 5 databases on a server. And each one has a test/ production split (so 10 total).
There is one sysadmin.
There is another person (non-sysadmin) who is responsible for the data, queries, tables, views, design, structure, indices, etc on DB Number #1. And that alone.
Do you grant SHOWPLAN/ View Server State permissions on DB Number #1 to the person responsible for its design, query optimization, etc? Or does that present an unacceptable security risks to a non sys-admin?
Perhaps it's a bit subjective or a gray area, but I wasn't sure. Are there specific patches/ procedures that can be put in place to mitigate these risks?
Are there any alternatives to SHOWPLAN when optimizing queries and query run time? What about sys.sql_expression_dependencies, also a related View Server State permission, correct?
Some may argue that you have a a DB_Development, DB_Test, and DB_Production split. Perhaps ideally, but when you only have the resources to implement a Test/ Production split, maybe access on Test alone is sufficient risk mitigation?
