Multiple filtering on one column
What if we are interested only in two models: let it be A4 and A5?
Of course, we could write WHERE model = 'A4' OR model = 'A5'. But is there a point in writing two conditions for the same column? This problem is also solved in SQL by using IN statement. To check if a value from a column is one of acceptable use WHERE column IN ('value1', 'value2', ...) syntax. For example,
123SELECT * FROM audi_cars WHERE model IN ('A4', 'A5')
WHERE column IN ('value1', 'value2')is equvivalent toWHERE column = 'value1' OR column = 'value2'. It also works for numeric values.

From audi_cars extract cars with engine size (enginesize column) 1.5 and 2.9 using IN statement.
