Sql query = "false"

[Chill_user]

Hello to all,

I have next query which gives "false" result, but data exists in the table.

$search_param = "test";
$query = 'SELECT *
        FROM `'._DB_PREFIX_.'test` 
        WHERE `link_rewrite` = '.$search_param;
$result = Db::getInstance()->ExecuteS($query);

If I make "Select *" from table = all is working.

Whats the problem with showed before code?

 

Thanks a lot!

$search_param = "'%".test."%'";
$query = 'SELECT *
        FROM `'._DB_PREFIX_.'test` 
        WHERE `link_rewrite` LIKE '.$search_param;
$result = Db::getInstance()->ExecuteS($query);

or

$search_param = "'".test."'";
$query = 'SELECT *
        FROM `'._DB_PREFIX_.'test` 
        WHERE `link_rewrite` = '.$search_param;
$result = Db::getInstance()->ExecuteS($query);

or

$search_param = 'test';
$query = "SELECT COUNT(`link_rewrite`) AS count
        FROM `"._DB_PREFIX_."test` 
        WHERE `link_rewrite` = ".$search_param;
$result = Db::getInstance()->getValue($query);

if ($result['count'] == '0') {
        echo 'URL rewrite: '.$search_param.' not exists';
    } else {
        echo 'URL rewrite: '.$search_param.' exists in databse. Count: '.$result['count'];
    }
