Question

I have a windows app which has MySQL backend. I have wampserver installed on my machine which bundles a certain version of phpmyadmin along with MySQL version 5.0.51a. But in client machines they have MySQL version 5.1. In short development is on 5.0, while deployment is on 5.1. This is creating a bit of issues for us, since those two versions behave slightly different. So I got a standalone setup of vesion 5.1 and installed on my (development) machine.

Now when I run my app, it needs either wamp services (version 5.0) turned on, or it needs MySQL 5.1 (standalone installation installed in Program Files>MySQL>…) Both ways work.

Question1: Am I right to assume my app is relying on MySQL 5.0 if only wamp service is turned on and on MySQL 5.1 if only original MySQL service is turned on? Yes I suppose.

Question2 (main question): The app works if I have both services turned on aswell. In that case how can I know which MySQL version is my app running on? All I have is a connectionstring which looks like:

 MySqlConnection con = new MySqlConnection("SERVER=localhost; DATABASE=wow; 
                                           UID=root;PASSWORD=; Min Pool Size = 0; 
                                           Max Pool Size=200");

Tool runs on C#.

Answer 1

You can always use SELECT VERSION(). That will answer both of your questions.
