query problem

[pixeltrace]

guys,

i need help, i dont know how to do this.
how will you set your sql query in such a way that i will just show the
last 5 data by date.
lets say, today is march 7, it will just show the 5 data from march 7 onwards
and once the date has expired or when there is no more data to show it
will print a comment saying "no current events"

need help.
thanks!

[code]

# First step: Receiving your 5 last data

$query = "SELECT * FROM ... WHERE ... ORDER BY date DESC LIMIT 5";

$result = mysql_query($query, $databaseconnection);

while (@$row = mysql_fetch_array($result)) {

        # Do something with your received data

} // while


# Second step: What is the highest date in db?

$query = "SELECT MAX(date) AS max  FROM ... ";

$result = mysql_query($query, $databaseconnection);

$row = mysql_fetch_array($result);

# date - format in db is datetime?
if ($row[max] < date("Y-m-d H:i:s")) {

      echo "no new updates";

} // if


[/code]

Code is written without deeper thinking and testing ... sorry, no time ! ;-)

[code]$query = "SELECT * FROM ... WHERE date = $dateToCheck ORDER BY date DESC LIMIT 5";

$result=mysql_query($query);
if (mysql_num_rows($result == 0)) die ("no results found for " . $dateToCheck);
[/code]

Make sense?!
