For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Select records from March

Posted by bschultz (bschultz), 30 April 2008
I'm trying to select only records from the month of March.

I've tried...

$sql = "SELECT date, title, text FROM table ORDER by date DESC WHERE `date` = DATE_SUB(CURDATE(),INTERVAL -2 month)";

and this...

$sql = "SELECT date, title, text FROM brian ORDER by date DESC WHERE `date` BETWEEN DATE_SUB(CURDATE( ) ,INTERVAL -2 MONTH) AND CURDATE( )";


Neither are working.  Can anyone help, please?

The first thing I notice is that you have quotes around date - you have written 'date' when I think it should be date.  With quotes you are looking to match exactly the letters d-a-t-e and not the contents of a field called date ...

Didn't work...I still get

Quote:
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /path/to/script.php on line 88

There are no news items for this month


I should add that "date" is set as timestamp (NOW) in the DB.  

I have also tried this code

Code:
$sql = "SELECT date(2008-03-00), title, text FROM brian ORDER by date DESC";


Which does display the proper results, but the dates are messed up.

2008-03-28 reads Wednesday, December 31, 1969 - 6:00 pm with this code

Code:
echo "<div class='calendarText'>".date('l, F j, Y - g:i a', strtotime($row['date']))."</div>";

this code works

Code:
$sql = "SELECT date_col, title, text FROM brian WHERE date_col BETWEEN '2008-03-01' AND '2008-04-01' order by date_col desc";


Thanks, Graham!
