Final answer:
The statement is FALSE; the ON clause can be used even if the columns do not have the same name, as long as they represent comparable data for the join condition.
Step-by-step explanation:
The statement that the ON clause can only be used if the tables being joined have a common column with the same name is FALSE. The ON clause is used in SQL to specify the conditions for joining tables, and indeed, it often utilizes columns that the tables have in common. However, the names of the columns do not have to be the same in both tables.
The key requirement is that the columns on either side of the join condition are able to be compared. For instance, one table may have a column named 'customer_id' while another table has a 'client_id' that refers to the same data. The ON clause can still be used to join these tables with a condition like ON table1.customer_id = table2.client_id.
