galvin Posted December 22, 2014 Share Posted December 22, 2014 I have these two tables... schedule (gameid, homeid, awayid, weekno, seasonno) teams (teamid, location, nickname) This mysql query below gets me schedule info for ALL 32 teams in an array... $sql = "SELECT h.nickname AS home, a.nickname AS away, h.teamid AS homeid, a.teamid AS awayid, s.weekno FROM schedule s INNER JOIN teams h ON s.homeid = h.teamid LEFT JOIN teams a ON s.awayid = a.teamid WHERE s.seasonno =2014"; $schedule= mysqli_query($connection, $sql); if (!$schedule) { die("Database query failed: " . mysqli_error($connection)); } else { // Placeholder for data $data = array(); while($row = mysqli_fetch_assoc($schedule)) { if ($row['away'] == "") {$row['away']="BYE";} $data[$row['homeid']][$row['weekno']] = $row['away']; $data[$row['awayid']][$row['weekno']] = '@ '.$row['home']; } } However, I only want to get info for one specific team, which is stored in the $teamid variable. This should be very easy, right? I have tried multiple things, including this one below (where I added an AND statement of "AND (h.teamid=$teamid OR a.teamid=$teamid)"), but this one still outputs too much... $sql = "SELECT h.nickname AS home, a.nickname AS away, h.teamid AS homeid, a.teamid AS awayid, s.weekno FROM schedule s INNER JOIN teams h ON s.homeid = h.teamid LEFT JOIN teams a ON s.awayid = a.teamid WHERE s.seasonno =2014 AND (h.teamid=$teamid OR a.teamid=$teamid)"; $schedule= mysqli_query($connection, $sql); if (!$schedule) { die("Database query failed: " . mysqli_error($connection)); } else { // Placeholder for data $data = array(); while($row = mysqli_fetch_assoc($schedule)) { if ($row['away'] == "") {$row['away']="BYE";} $data[$row['homeid']][$row['weekno']] = $row['away']; $data[$row['awayid']][$row['weekno']] = '@ '.$row['home']; } } Below is the array that the above outputs. In a nutshell, all I want is that 1st array ([1]) which has, in this example, the Eagles full schedule. It's not giving me too much else and I guess I could live with it and just ignore the other stuff, but I'd rather be as efficient as possible and only get what I need... Array ( [1] => Array ( [1] => Jaguars [2] => @ Colts [3] => Redskins [4] => @ 49ers [5] => Rams [6] => Giants [7] => BYE [8] => @ Cardinals [9] => @ Texans [10] => Panthers [11] => @ Packers [12] => Titans [13] => @ Cowboys [14] => Seahawks [15] => Cowboys [16] => @ Redskins [17] => @ Giants ) [27] => Array ( [1] => @ Eagles ) [28] => Array ( [2] => Eagles ) [4] => Array ( [3] => @ Eagles [16] => Eagles ) [14] => Array ( [4] => Eagles ) [15] => Array ( [5] => @ Eagles ) [3] => Array ( [6] => @ Eagles [17] => Eagles ) [] => Array ( [7] => @ Eagles ) [16] => Array ( [8] => Eagles ) [25] => Array ( [9] => Eagles ) [11] => Array ( [10] => @ Eagles ) [7] => Array ( [11] => Eagles ) [26] => Array ( [12] => @ Eagles ) [2] => Array ( [13] => Eagles [15] => @ Eagles ) [13] => Array ( [14] => @ Eagles ) ) Link to comment https://forums.phpfreaks.com/topic/293224-trying-to-limit-data-that-comes-back-from-mysql-query-into-array/ Share on other sites More sharing options...
Barand Posted December 22, 2014 Share Posted December 22, 2014 One suggestion that I would make is to change the WHERE condition. You are doing a left join on table a so there may not be a matching record so use the schedule table ids in the where clause. I.E. change AND (h.teamid=$teamid OR a.teamid=$teamid) to AND (s.homeid=$teamid OR s.awayid=$teamid) or you could use this alternative AND $teamid IN (s.homeid, s.awayid) Link to comment https://forums.phpfreaks.com/topic/293224-trying-to-limit-data-that-comes-back-from-mysql-query-into-array/#findComment-1500345 Share on other sites More sharing options...
