I'm building an application where it is asking the user for SQL Credentials to make Schema Updates. The credentials can be either and SQL User & Password or Trusted Connection (ie the currently logged on windows user).

Now, if the user uses Trusted Connection, the application created a connection string and connects. But how can it be sure that the user is an SQL Admin before the Schema Update starts?

Thanks

IS_MEMBER function checks whether the current user is a member of the specified windows or sql database role. And to check specifically for object level permissions, see PERMISSIONS function.

Although it's not exactly what I needed, I found the Function Is_SrvRoleMember('SysAdmin') from it's help page.

Testing for sysadmin is not really the right thing to do in this case. Best practice is to use the lowest possible permissions needed to complete a task.

The permission needed is ALTER ANY CREDENTIAL and you should test for this. It is possible to grant this permission to any user, so you do not need to be a Sysadmin in order to create a credential.

My feeling is that if an application has any more than (at the most) read/write privs, then the application is incorrectly written. The application should be calling on prived stored procedures to do the job safely.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
