There are a number of good introductory SQL resources available for free and online. There are also some paid resources which I recommend for beginners, that are very effective, and well worth expensing in my opinion.

A couple of notes:

• I haven’t used all of these resources, but they come with strong recommendations around the web or myself/my peers.
• You absolutely don’t need to use every single resource. Find a couple that work for you, and go to town.
• You can always reach out to me if you have questions. I always paste this online when people are new to asking very technical questions – it’s not meant to be snarky – it's a gentle guide on how to compose your questions and gather necessary resources in order to best give technical people the information needed to get a quick/effective response: http://www.mikeash.com/getting_answers.html

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
