SQL：从我的SQL查询的日期值中减去1天

Question

I have this query:

SELECT * FROM booking WHERE '$year/$month/$day' BETWEEN arrivalDate AND departureDate

Where arrivalDate and departureDate are date values in my tables columns.

How can I check for the day before departureDate?

IE: departureDate - 1 day

Answer 1

You're almost there, there is - INTERVAL 1 DAY for this:

SELECT * FROM booking WHERE '$year/$month/$day' BETWEEN arrivalDate AND departureDate - INTERVAL 1 DAY
