How to join three tables in SQL query – MySQL Example

Three table JOIN Example SQL
Joining three tables in single SQL query can be very tricky if you are not good with the concept of SQL Join. SQL Joins have always been tricky not only for new programmers but for many others,  who are in programming and SQL for more than 2 to 3 years. There are enough to confuse someone on SQL JOIN ranging from various types of SQL JOIN like INNER and OUTER join, LEFT and RIGHT outer join, CROSS join etc. Between all of these fundamentals, What is most important about Join is, combining multiple tables. If you need data from multiple tables in one SELECT query you need to use either subquery or JOIN. Most of the times we only join two tables like Employee and Department but sometimes you may require joining more than two tables and a popular case is joining three tables in SQL.
