Answer 1

The version of mysql client is not relevant. The functionality exists (or in your case does not exist) in the mysql server. Thus the only thing that's relevant is the mysql server version. And this functionality is available only in mysql server 5.7 onwards. Upgrading your client will not solve the problem, you need to upgrade your server.

Is there a work around? yes. PHP's json_decode

This can work because your query does not have a WHERE clause. You are looking at the entire table. So you can just as easily fetch all that data and json_decode and then do the processing in your PHP code. This is going to be very slow if you have a lot of data though.
