NoSQL databases lack consistency across products and typically require more work to query data, particular as query complexity increases.

Is it better to learn SQL or NoSQL?

If your data is very structured and ACID compliance is a must, SQL is a great choice. On the other hand, if your data requirements aren't clear or if your data is unstructured, NoSQL may be your best bet. The data you store in a NoSQL database does not need a predefined schema like you do for a SQL database.

What should I learn first SQL or NoSQL?

It is only when a traditional SQL database doesn't meet my needs that I consider a NoSQL database. With that said, I would say learn SQL first. You will learn a lot about database design, normalization and you'll learn the importance of ACID-compliance. Then go learn NoSQL if you think you really need to.
