Let’s get started.
What are MySQL Joins?
MySQL joins are an essential element in relational database management systems such as MySQL. They enable you to merge data from two or more tables based on a shared column.
Joins allow you to get information that is dispersed across different tables, making it easier to analyse and alter data. They are required for complicated searches and obtaining significant insights from a database.
Types of MySQL Joins
As per the documentation we have following types of joins available –
- Inner Join
- Left Join
- Right Join
- Cross Join
Inner Join
This join brings the data on the basis of a common value condition between two or more than two tables. According to matched condition it will bring all data what we expected for. It remove those rows from result set which has no matched condition.

Left Join
Left join works same the matched condition between two or more than two tables. But in this case we also get the rows of left table which doesn’t match with the condition with the right hand sided table. Means we get all rows of left table including values of matched with right table.

Right Join
Right join works same the matched condition between two or more than two tables. But in this case we also get the rows of right table which doesn’t match with the condition with the left hand sided table. Means we get all rows of right table including values of matched with left table.
Cross Join
Cross joins generate a Cartesian product between the first table and the joined table.
