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.

Change is inevitable... Change for the better is not.
