in reply to (OT) parsing time in mysql

I think, 
SELECT * from `your_table_name` WHERE DAY(time) = DAY(NOW())

[download]
 
SELECT * from `your_table_name` WHERE 
  YEAR(time) = YEAR(NOW()),
  DAYOFYEAR(time) = DAYOFYEAR(NOW())

[download]
etc. will work.

MySQL has corresponding WEEK, YEAR and MONTH functions, too.

I assumed that you are using MySQL 4.1.1 or above. It not, use DATE_FORMAT with corresponding formatstring instead.

UPD:I wanted to give a quick and dirty answer, but this answer was TOO dirty :) Bug is now corrected.

    I was really looking for a more PERLish way to do this. I tried this solution and I had odd results. It brought back results from other months that occured on the same day. Today was the 11th, it showed data on the 11th over the past few months.

    Anyway around this?

      I posted wrong request :( But it can be easily extended to become right: 
      -- today
SELECT * from `your_table_name` WHERE 
  YEAR(time) = YEAR(NOW()),
  DAYOFYEAR(time) = DAYOFYEAR(NOW())

--this month
SELECT * from `your_table_name` WHERE 
  YEAR(time) = YEAR(NOW()),
  MONTH(time) = MONTH(NOW())

--this week (USA) (simple solution with WEEK() 
--won't work at the beginning of the year
SELECT * from `your_table_name` WHERE 
  YEARWEEK(time, 0) = YEARWEEK(NOW(), 0)

      Rewriting of the request to use DATE_FORMAT can be performed according to the docs.

      I don't know if it's a Perlish way, but it's a RIGHT way. SELECT must select only the data you want, and it's faster and cleaner to perform all heavy-weight data filtering on the database side.

        It almost hurts me to ask this, but what do you mean 'more Perlish'? MySQL isn't very perlish at all, unfortunately.
        However... you might try heavy use of wild-carding. That's sort of perlish. 
        select * from mytable where date like curdate.'%' ;

        Or something.
