mysqlbetween

What's mysql's "BETWEEN" performance over..?

Is there any better performance when querying in (particularly) mysql of the following:

SELECT * FROM `table` WHERE `unix_date` BETWEEN 1291736700 AND 1291737300

over:

SELECT * FROM `table` WHERE `unix_date` >= 1291736700 AND `unix_date` <= 1291737300

or BETWEEN syntax is just being substituted with the second sql?

Solution

  • As I recall, there's no difference. But see for yourself if: 

    explain plan for 
SELECT * FROM `table` WHERE `unix_date` BETWEEN 1291736700 AND 1291737300

    and:

    explain plan for
SELECT * FROM `table` WHERE `unix_date` >= 1291736700 AND `unix_date` <= 1291737300

    produce the same plans.
