That requires your application to be vulnerable to two types of exploit in order to pull off RCE - if you are vulnerable to SQLi there are likely a whole raft of other issues which would give you a remote shell.
As a standalone issue I agree with the GP comment - this bug is not a RCE issue, it's privilege escalation.
