  • SQL Join | Definition , Types
    and Examples

    SQL Join combines rows from two or more tables.

    • When data from more than one table in the database is required, a join condition is used.
    • Rows in one table can be joined to rows in another table according to common values existing in corresponding columns, that is, usually primary and foreign key columns.
    • To display data from two or more tables, we can write a simple join condition in the WHERE clause.

    Syntax:

    FROM table1
    JOIN_TYPE table2
    ON JOIN_CONDITION

    Example:

    Select * from Employee 
    INNER JOIN Department
    ON Employee.departmentID= Department.departmentID
