How do I add wildcards % to the "specifications.sn" ?
SELECT `products2`.`type`,
`products2`.`sn`,
`products2`.`lap`,
`specifications`.`year`
FROM `products2`
INNER JOIN `specifications`
ON `products2`.`sn` LIKE `specifications`.`sn`
WHERE `products2`.`id` = ? LIMIT 1
EDIT:
Added current query
Added your CONCAT
SELECT products2.type, products2.sn, products2.lap, specifications.year FROM products2 INNER JOIN specifications ON products2.sn LIKE CONCAT('%', specifications.sn, '%') WHERE products2.id = ? LIMIT 1
Alternative query - Same error like code above
Added LIKE in WHERE statement
SELECT products2.type, products2.sn, products2.lap, specifications.year FROM products2, specifications WHERE products2.id = ? AND products2.sn LIKE '%' + specifications.sn + '%' LIMIT 1
EDIT2
PHP code
if ($stmt = $mysqli->prepare('SELECT products2.type,
products2.sn,
products2.lap,
specifications.year
FROM products2
INNER JOIN specifications
ON products2.sn LIKE CONCAT('%', specifications.sn, '%')
WHERE products2.id = ? LIMIT 1')) {
$stmt->bind_param('i', $id);
$id = $_GET['id'];
$stmt->execute();
$stmt->bind_result($type, $sn, $lap, $year);
$stmt->fetch();
echo $type . '<br/>';
echo $sn . '<br/>';
echo $lap . '<br/>';
echo $year . '<br/>';
$stmt->close();
} else {
echo $mysqli->error;
}
SELECT `products2`.`type`,
`products2`.`sn`,
`products2`.`lap`, `specifications`.`year`
FROM `products2`
INNER JOIN `specifications`
ON `products2`.`sn` LIKE
CONCAT(`specifications`.`sn`, '%')
WHERE `products2`.`id` = ? LIMIT 1
Please note the following:
CONCAT(NULL, 'ADADSA')
returns NULL
, therefore you have to take care of this special use case if you think specifications
. sn
might be NULL. Cheers.
