Final answer:
The statement is false; joins between tables are primarily specified in the From clause using JOIN keywords, not the Where clause. The Where clause is used to filter data based on criteria after the join has been performed.
Step-by-step explanation:
The statement that either the From clause or the Where clause can be used to join tables together is false. In SQL, joins between tables are typically specified in the From clause of a select statement. The Where clause, on the other hand, is used primarily to filter data based on certain criteria, though in some cases it can be used to specify joins, but not in the standard, modern way of writing SQL.
To perform a join, you would typically use the From clause along with JOIN keywords such as INNER JOIN, LEFT JOIN, RIGHT JOIN, or FULL JOIN, specifying the tables you are joining along with the condition for the join. The Where clause would then be used to further filter the results of the joined tables based on specific conditions.
For example, consider two tables, Students and Classes, to demonstrate the use of the From clause in a join:
SELECT Students.Name, Classes.ClassName
FROM Students
INNER JOIN Classes ON Students.ClassID = Classes.ID;
This query uses the From clause to join the Students table with the Classes table based on a common field that relates records from one table to the other.
