• If I can suggest something.

    Have a look at the SQL server MS exams to get to MCSA for SQL server. I think it's 70 461,462,463.

    Have a look at the skills measured break this down into a matrix. Then start going through each one till you are happy with it. Then take the exams. Then you have created a formal training program for yourself and got certified.

    There are plenty of you tube clips on the various subjects and if you get stuck people will give you pointers.

    Best of luck
