Query code:
$query = $this->db->query(
'SELECT course.*, AVG(course_review.`rating`) AS `avg_rating`
FROM course
LEFT JOIN course_review ON `course`.`id` = `course_review`.`course_id`
WHERE `course`.`course_category`= ' . $id . '
AND `course`.`approved`= 3
AND `course`.`delete_course` != 1
AND `course`.`unpublish_course` != 1
GROUP BY `course`.`id`
ORDER BY avg_rating DESC');
return $query->result()
Thanks
You can try this Query for your problem :
Query:-
$query = $this->db->query('SELECT
course.id,
AVG(course_review.rating) AS avg_rating
FROM course
LEFT JOIN course_review
ON course.id = course_review.course_id
WHERE course.course_category = ' . $id . '
AND course.approved = 3
AND course.delete_course != 1
AND course.unpublish_course != 1
GROUP BY course.id
ORDER BY avg_rating DESC');
return $query->result();

I'm using Slim with PDO with MySql for return a specific list of matches available in my database. My query is this:
SELECT m.*,
t.name AS home_team_name,
t2.name AS away_team_name
FROM `match` m
LEFT JOIN team t ON m.home_team_id = t.id
LEFT JOIN team t2 ON m.away_team_id = t2.id
WHERE (home_team_id = 117 OR away_team_id = 117) AND round_id = 488
if I execute this query I'll get a list of matches:
but inside the API developed with Slim I get an empty array. This is the method structure:
$app->get('/match/get_matches_by_team/{round_id}/{team_id}/{type}', function (Request $request, Response $response, array $args)
{
$query = "SELECT m.*,
t.name AS home_team_name,
t2.name AS away_team_name
FROM `match` m
LEFT JOIN team t ON m.home_team_id = t.id
LEFT JOIN team t2 ON m.away_team_id = t2.id
WHERE ";
switch($args["type"])
{
case "home":
$query .= "home_team_id = :team_id AND ";
break;
case "away":
$query .= "away_team_id = :team_id AND ";
break;
default:
$query .= "(home_team_id = :team_id OR away_team_id = :team_id) AND ";
break;
}
$query .= "round_id = :round_id";
$sql = $this->db->prepare($query);
$sql->bindParam("team_id", $args["team_id"]);
$sql->bindParam("round_id", $args["round_id"]);
$sql->execute();
$result = $sql->fetchAll();
return $response->withJson($result);
});
what I did wrong?
Thanks in advance for any help.
UPDATE
If I do echo $query; return; I'll get:
SELECT m.*,
t.name AS home_team_name,
t2.name AS away_team_name
FROM `match` m
LEFT JOIN team t ON m.home_team_id = t.id
LEFT JOIN team t2 ON m.away_team_id = t2.id
WHERE away_team_id = :team_id AND round_id = :round_id
supposing to pass away, if instead I pass all I'll get:
SELECT m.*,
t.name AS home_team_name,
t2.name AS away_team_name
FROM `match` m
LEFT JOIN team t ON m.home_team_id = t.id
LEFT JOIN team t2 ON m.away_team_id = t2.id
WHERE (home_team_id = :team_id OR away_team_id = :team_id) AND round_id = :round_id
UPDATE 2
Method updated with proposed hints
$app->get('/match/get_matches_by_team
/{round_id}/{team_id}/{type}', function (Request $request, Response $response, array $args)
{
$query = "SELECT m.*,
t.name AS home_team_name,
t2.name AS away_team_name
FROM `match` m
LEFT JOIN team t ON m.home_team_id = t.id
LEFT JOIN team t2 ON m.away_team_id = t2.id
WHERE ";
switch($args["type"])
{
case "home":
$query .= "home_team_id = :home_team_id
AND ";
break;
case "away":
$query .= "away_team_id = :away_team_id AND ";
break;
default:
$query .= "(home_team_id = :home_team_id OR away_team_id = :away_team_id) AND ";
break;
}
$query .= "round_id = :round_id";
$sql = $this->db->prepare($query);
$sql->bindParam("home_team_id", $args["team_id"]);
$sql->bindParam("away_team_id", $args["team_id"]);
$sql->bindParam("round_id", $args["round_id"]);
$sql->execute();
$result = $sql->fetchAll();
return $response->withJson($result);
});
yours:
$sql->bindParam("team_id", $args["team_id"]);
$sql->bindParam("round_id", $args["round_id"]);
try this, the params might be needed to be formatted differently
$sql->bindParam(":team_id", $args["team_id"], PDO::PARAM_INT);
$sql->bindParam(":round_id", $args["round_id"], PDO::PARAM_INT);
or
$sql->bindParam(":team_id", $args["team_id"]);
$sql->bindParam(":round_id", $args["round_id"]);
When the default switch is selected, you are trying to bind a value with the same parameter marker (in your case :team_id) twice. In order for this to work you have to turn on emulation mode in PDO.
http://www.php.net/manual/en/pdo.prepare.php
You must include a unique parameter marker for each value you wish to pass in to the statement when you call PDOStatement::execute(). You cannot use a named parameter marker of the same name more than once in a prepared statement, unless emulation mode is on.
I got
for($i = $start_date;$start_date <= $end_date;$i->modify('+1 day')) {
$i->format('Y-m-d').'<br />';
$dates = $i->format('Y-m-d');
echo $query = "
SELECT md.dish_id
, md.daydate
, d.id
, d.dish_name
, d.weight
, d.price

LEFT
JOIN menu_details md
ON d.id = md.dish_id
WHERE md.daydate = '$dates'
";
$result = mysql_query($query);
}
while($row = mysql_fetch_array($result)) {
echo 'Date: '.$row['daydate'].'Name: '.$row['dish_name'].'<br />';
}
how can i row 'dish_name' for every date on a new row.In the database there are more then 1 row with same date=
You should try to avoid running queries in loops...
Try:
$query = "SELECT md.dish_id, md.daydate, d.id, d.dish_name, d.weight, d.price
FROM dishes d
LEFT JOIN menu_details md ON (d.id = md.dish_id)
WHERE md.daydate BETWEEN '$start_date' AND '$end_date'
GROUP BY md.daydate ";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)) {
echo 'Date: '.$row['daydate'].'Name: '.$row['dish_name'].'<br />';
}
What is the group by for? I think it may cause you to lose some of the results...
I have two separate SQL queries that I would like to combine to a single one if possible.
Query #1 yields all entries from a table in random order
Query #2 will afterwards check whether or not the result can be used
How can I achieve this in a single step directly in SQL?
Code:
// start with a query for all of the photos, returned in random order
$query = "
SELECT DISTINCT m.mediaID
, m.description
, m.path
, m.alwayson
, m.usecollfolder
, m.mediatypeID
FROM $media_table m
WHERE m.mediatypeID = 'photos'
ORDER BY RAND();
";
$result = mysql_query($query) or die ("$text[cannotexecutequery]: $query");
while( $imgrow = mysql_fetch_assoc( $result ) ) {
// if the picture is alwayson or we are allowing living to be displayed,
// we don't need to bother
// with any further checking
if ($imgrow[alwayson] || $allow_living_db ) {
break;
// otherwise, let's check for living
} else {
// this query will return rows of personIDs on the photo that are living
$query = "
SELECT l.personID
FROM $medialinks_table l
JOIN $people_table p ON l.personID = p.personID
WHERE l.mediaID = $imgrow[mediaID]
AND p.living = 1
";
$presult = mysql_query($query) or die ("$text[cannotexecutequery]: $query");
$rows = mysql_num_rows( $presult );
mysql_free_result( $presult );
// if no rows are returned, there are no living on the photo, so let's display it
if ($rows == 0) {
break;
}
}
SELECT DISTINCT m.mediaID
, m.description
, m.path
, m.alwayson
, m.usecollfolder
, m.mediatypeID
, l.personID
FROM $media_table m
JOIN $medialinks_table l
ON l.mediaID = m.mediaID
JOIN $people_table p
ON l.personID = p.personID
WHERE m.mediatypeID = 'photos'
AND p.living = 1
ORDER

Could you please change this query so that it returns all records in table while using WHERE clause so that I could search a particular record if needed. At the moment it does not return anything:
select *, sum(price+shipping+paypalfee+storefee) as totalcost
from tblsales
group by orderno
where " . $where . "
order by $sort $order
limit $offset,$rows
Try this
select *,sum(totalcost)
FROM (select *, price+shipping+paypalfee+storefee as totalcost from tblsales) x
group by orderno
where " . $where . "
order by $sort $order
limit $offset,$rows
I want to display news, for example from yesterday. Here's what my query looks like. Is there any magical line of code which would do that?
$query = '
SELECT a.*,
CASE WHEN CHAR_LENGTH(a.alias) THEN CONCAT_WS(":", a.id, a.alias)
ELSE a.id END as slug,
CASE WHEN CHAR_LENGTH(b.alias) THEN CONCAT_WS(":", b.id, b.alias)
ELSE b.id END as catslug,
b.title as category_title,
b.alias as categoryalias,
b.params as categoryparams,
u.name AS author
FROM #__content as a
LEFT JOIN #__categories as b ON a.catid = b.id
LEFT JOIN #__users AS u ON u.id = a.created_by
WHERE ' . $where. '
ORDER BY ' . $orderby. '
LIMIT ' . $limit;
The "magical" line of code should be in your WHERE clause.
e.g. if you date is only YYYY-MM-DD
$query .= 'WHERE b.created_date = '.$db->quote( date('Y-m-d', strtotime('-1 day')) ).'
e.g. if your date column is YYYY-MM-DD H:i:s
$query .= 'WHERE DATE_FORMAT(b.created_date,"%Y-%m-%d") = '.$db->quote( date('Y-m-d', strtotime('-1 day')) ).'
