MySQL compare DATE string with string from DATETIME field

Question

I have a question: Is it possible to select from a MySQL database by comparing one DATE string \"2010-04-29\" against strings that are stored as DATETIME (2010-04-29 10:00)?

Answer 1

SELECT * FROM `calendar` WHERE DATE_FORMAT(startTime, "%Y-%m-%d") = '2010-04-29'"

OR

SELECT * FROM `calendar` WHERE DATE(startTime) = '2010-04-29'
