Learning SQL and becoming involved in the technical community can be difficult if you do not know where to look. A fantastic event that encourages people of all ability levels is through PASS. PASS is an independent, not-for-profit organization run by and for the community.
One event that they offer for each of their communities is SQL Saturday. This event takes an entire Saturday for free training sessions that varies in topics. The sessions are offered once a year per area and have a variety of locations around the work. They can include technical sessions lead by many local speakers. I encourage checking out the calendar to see when it is offered in your area. Sessions are available all around the world.
If you are interested in becoming a DBA, please consider attending an event near you and supporting your community.
