Question

With MySQL what is the method of doing a datetime comparison with precision? Like I want to compare two dateTime fields to see if their equal ignorming minutes and seconds, saying:

[compare with precision down to hours] 
Is 2011-05-05 14:32:49 equal to 2011-05-05 14:46:22 ?
=> TRUE

I’m not sure there is anything, and google isn’t helping (precision just brings up a bunch of results about milli and micro second junk). Maybe this type of compare is dervied from another function and there isn’t a date compare w/ precision in MySQL?

Thanks!

You could try:

DATE(dt1) = DATE(dt2) AND HOUR(dt1) = HOUR(dt2)

Take a look at MySql Date-Time functions
