I have a query that i need to get only the rows that are for the current year.

The column that has the unix time is referrals.entered

here is the current query:

SELECT referrals.*, to_person.fname as to_fname, to_person.lname as to_lname, from_person.fname as from_fname, from_person.lname as from_lname FROM referrals LEFT JOIN person as from_person ON (from_person.ID = referrals.from_ID) LEFT JOIN person as to_person ON (to_person.ID = referrals.to_ID) LEFT JOIN chapter_relation as from_relation ON (from_person.ID = from_relation.person_ID) LEFT JOIN chapter_relation as to_relation ON (to_person.ID = to_relation.person_ID) WHERE from_relation.chapter_ID = to_relation.chapter_ID AND from_relation.chapter_ID = '$chapterid' ORDER BY referrals.entered DESC

There is nothing in your query where you filter on year so

WHERE
....
YEAR(referrals.entered)=2014
....

Or did you mean for this to be a generic sql for whatever the current year is?

WHERE
....
YEAR(referrals.entered)=YEAR(CURDATE())
....

Well maybe i answered my own question... but i just did it this way unless you think it could be better:

$currentyear = date('Y');
$startyear = strtotime("01 January ".$currentyear);
$endyear = strtotime("31 December ".$currentyear);

$numberreferrals = mysqli_query($mysqliglobal,"SELECT referrals.*, to_person.fname as to_fname, to_person.lname as to_lname, from_person.fname as from_fname, from_person.lname as from_lname FROM referrals LEFT JOIN person as from_person ON (from_person.ID = referrals.from_ID) LEFT JOIN person as to_person ON (to_person.ID = referrals.to_ID) LEFT JOIN chapter_relation as from_relation ON (from_person.ID = from_relation.person_ID) LEFT JOIN chapter_relation as to_relation ON (to_person.ID = to_relation.person_ID) WHERE from_relation.chapter_ID = to_relation.chapter_ID AND from_relation.chapter_ID = '$chapterid' AND referrals.entered > $startyear AND referrals.entered < $endyear ORDER BY referrals.entered DESC");

I think it's easier going the sql route, and just pass in the year from php using
$year = date("Y");
...
WHERE
....
YEAR(referrals.entered)=$year
....

Open in new window



Doing a date > and date < is just wasted code.
Plus the way you have it it would be
year > 2014 and year < 2014 = nothing

Ahh true - thought you were querying against the year, still it would be easier and less code to just query on the year as exampled here http:#a40512263

edit.
Your code is still > than the 1st of Jan and < 31st Dec which means the 2nd Jan til the 30th Dec
Should >= and <=

Just a reminder: use >= and <= otherwise you'll miss the data from the first and the last day of the year!
