Learning SQL was one of the most valuable skills I learned while building Match. We had one of the largest instances of Microsoft SQL Server in the 90s with millions of records to keep the site running. The better we got at SQL, the better we could make the site work for our users and answers sophisticated questions about our users.

• Basic selection statements
• Joining multiple tables together

Who this course is for:

• Entrepreneurs trying to build their MVP
• Anyone needing to talk to a database
