date compare syntax

[ionnnnutz]

<?php
$actDate=date("d.m.Y");
echo $actDate;

$activitate_zilnica2=("SELECT comp_notesid,date_format(comp_note_entry_date, '%d.%m.%Y') AS entry_date,comp_note_message FROM comp_pnote WHERE entry_date = '".$actDate."'");
$activitate_zilnica=mysql_query($activitate_zilnica2);
while($activitate_zi=mysql_fetch_array($activitate_zilnica))
{
echo "<div><span>", $activitate_zi['entry_date'], "</span><br><span>", $activitate_zi['comp_note_message'], "</span></div><br>";
}

?>

$activitate_zilnica2=("SELECT comp_notesid,date_format(comp_note_entry_date, '%d.%m.%Y') AS entry_date,comp_note_message FROM comp_pnote WHERE entry_date = '".$actDate."'");

i wonder if that is the right syntax to compare 2 dates! Could somebody help me?

Typically you store your dates as unix timestamps.  Then get all of the records for one day by using a range of seconds (midnight one day to midnight the next).  This is relatively convenient and also the most efficient query.

Ditto. That way you don't have to deal with the different date formatting issues. (1/1/07 vs 01/01/07 vs 01/01/2007 vs 01-01/07 vs 07-1-1 , etc.)

but how should look the mysql query?

[veridicus]

Looks like you just want everything after midnight today (based on your code), so assuming comp_note_entry_date is a unix timestamp, you'll want something like...

 

<?php
$actDate=date("d.m.Y");
echo $actDate;

$beginning_of_day = time() - (time() % 86400);

$activitate_zilnica2=("SELECT comp_notesid,date_format(comp_note_entry_date, '%d.%m.%Y') AS entry_date,comp_note_message FROM comp_pnote WHERE comp_note_entry_date >= ".$beginning_of_day);
$activitate_zilnica=mysql_query($activitate_zilnica2);
while($activitate_zi=mysql_fetch_array($activitate_zilnica))
{
echo "<div><span>", $activitate_zi['entry_date'], "</span><br><span>", $activitate_zi['comp_note_message'], "</span></div><br>";
}

?>

mysql stores dates as YYYY-MM-DD

Actually, you should store your dates and DATE/DATETIME columns -- let mysql deal with storage.
