Hello,
I would like to learn SQL online, does anyone have any suggestions on a good
online course? I googled and found many but am not sure which one is good.
I have some CS background but don't know SQL well.
Thanks!

I am using Teradata, but if there is a good course on similar DB, that will be also very helpful.

distribution key), the fastest join performed on teradata is hash-join based
