boolean - How to query mysql without a table? -

i wonder if can simple boolean check mysql. mean can like

select date(`2013-03-25 01:22:26`) = curdate() 

to return true or false?

or php equivalent of case work, want learn this. using mysql such goal unnecessary ?

just remove where clause , use single quote around date.

select date('2013-03-25 01:22:26') = curdate()
