LEFT JOIN in SQL

LEFT JOIN/LEFT OUTER JOINย clause select all the records from left table(table1) and the matching records from the right table(table2).

Syntax of LEFT JOIN in SQL-

SELECTย <column_name(s)>

FROMย <table1>

LEFT JOIN<table2>

ONย <table1.column_name=table2.column_name>

WHERE<condition>;

Example of LEFT JOIN in SQL-

SELECTย Customers.CustomerName, Orders.OrderID

FROMย Customers

LEFT JOINย Orders

ONย Orders.CustomerID = Customers.CustomerID;

LEFT JOIN returns all records from the left table (Customers), even if there are no matches in the right table (Orders). In the above example, SQL statement will select all customers and their orders.
