How many tables may be included with a join?
AnswerClick to flip back
A
all of the above
💡 Explanation:
SQL joins can theoretically involve any number of tables. While 2-table joins are most common (inner, left, right, full joins), you can join 3, 4, or more tables in a single query by chaining join conditions. The 'all of the above' option correctly captures that 1, 2, 3, or more tables are all possible.
