Explanation / Answer
1. To join three tables using the SQL, I will need (x) equations in the WHERE statement.
Answer: Zero or more
Example:
SELECT *
FROM table1 AS t1
INNER JOIN table2 AS t2
ON t1.column1 = t2.column1
INNER JOIN table3 AS t3
ON t2.column2 = t3.column1;
From the above example. There is no where statement. So, answer is zero or more
