Please does one need to know any programming language before learning SQL Fundamentals?

Answer 1

Nope. SQL is not really a programming language so no prior knowledge in programming is required. Just a bit of an idea on how databases work is enough.

Answer 2

SQL goes very well with PHP although it is not necessary if you just want to learn the fundamentals. You can always learn PHP later.

Answer 3

"SQL (Structured Query Language) is a computer language aimed to store, manipulate, and query data stored in relational databases. " That means you can select data, calculate and prepare data for the future analysis or interpretation. To do this you write queries (f.e. SELECT * FROM database WHERE some rule). It has very different logic from the common iterative programming and for sure SQL is a powerful tool in data analysis.
