Notice that the new column, "Date Of Birth", is of type date and is going to hold a date.

Summary: in this tutorial, we will introduce you another kind of joins called SQL LEFT JOIN that allows you to retrieve data from multiple tables.
In the previous tutorial, you learned about the inner join that returns rows if there is, at least, one row in both tables that matches the join condition. When we join table A with table B, all the rows in table A (the left table) are included in the result set whether there is a matching row in the table B or not.
Inner join is used to select rows from multiple tables based on a matching column in one or more tables.
It compares each row value of a table with each row value of another table to find equal values.
