How do I use a LIKE clause in a PDO prepared statement?

Question

I have a sql query like this:

SELECT * FROM tbl_name WHERE title Like "%:needle%"

When I query the MySQL db manually with this statement it works. But when I use it with PDO and with the same values for :needle as I queried manually It just returns an empty result set.

Does utf8 encoding affects the behavior of it?

Answer 1

With PDO, this can be done like:

$stmt = $db->prepare("SELECT * FROM tbl_name WHERE title LIKE :needle");
$needle = '%somestring%';
$stmt->bindValue(':needle', $needle, PDO::PARAM_STR);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

Answer 2

try like

$sql = 'SELECT * FROM tbl_name WHERE title Like ":needle"';

$prep = $dbh->prepare($sql);

$ret = $prep->execute(array(':needle' => '%'.$somestring.'%'));

Answer 3

The '%' needs to be in the variable, not the statement. Put the '%' in the variable, and you should be fine.

'SELECT * FROM tbl_name WHERE title Like ":needle"'

$needle = "%$needle%"; 

Answer 4

This worked for me:

$sql = $conn->prepare("select * from itens where nome LIKE :nome");
$nome = "%".$item->getName()."%";  
$sql->bindParam("nome",$nome);
