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

Use the following:

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

Just for reference I have a 2 million record table, I ran a similar query. Salils answer took 4.48 seconds, the above took 2.25 seconds.

So if the table is BIG I would suggest this rather.
