If you look forward to being a data scientist or want to refresh your mind of SQL, or just want to practice SQL databases, then I made this course for you. This is not a theoretical course; this is a very practical course

In this course, you will learn how to create a table, insert values into it, use and understand some data types, use SELECT statements, UPDATE records, use some aggregate functions like COUNT(), MIN(), SUM(), use WHERE clause, remove a character from a string, cast a string to numeric values, write subquery, retrieve the top and bottom candidates, add a column, do a for loop, and make a histogram.
