What is a join? Explain the different types of mysql joins.
The SQL statement that is used to make a connection between two or more tables based on the matching columns is called a join. It is mainly used for complex queries.
Different types of SQL joins are mentioned below:
Inner Join: It is a default join. It returns records when the values match in the joining tables.
Left Outer Join: It returns all the records from the left table based on the matched records from the right table.
Right Outer Join: It returns all the records from the right table based on the matched records from the left table.
Full Outer Join: It returns all the records that match from the left or right table.
