@sebastienroul could you please add tests?

[sebastienroul]

@kibertoad Hi, yes sure, but can you give me pointer to the test written for the select statement please, I cant find them (µI'd like to use them as template). For your info PR is working like a charm on 10 of our projects :)

@kibertoad : Finally, unit test + integration test are there.
I clear my first attempt to modify all dialect, and focus only on MYSQL. Everything is green... let pull :)
