A SQL Join statement is used to combine data or rows from two or more tables based on a common field between them.
Different types of Joins are:
1. INNER JOIN
Select records that have matching values in both tables.
2. LEFT JOIN
Select records from the first (left-most) table with matching right table records.
3. RIGHT JOIN
Select records from the second (right-most) table with matching left table records.
4. FULL JOIN
Selects all records that match either left or right table records.
