Mysql update all columns starting with same Name

Question

I have a dynamic table named 'products' with multiple Languages. The table columns looks like this:

id, product_id, store_de, store_en, store_fr, store_es... etc

The languages can be more or less.

Now I want to update this table and set all columns beginning with "store_" to value 1.

I tried the following:

$stmt = $dbh->prepare( "UPDATE products SET `store_%` = ? WHERE product_id = ?" );

$stmt->execute( array( 1, $lastID ) );

I get following error message:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'store%' in 'field list'

Is there a way to update all columns beginning with 'store_' or do I have to list all the columns?

Based on the answer from jekaby here is the full solution that worked for me:

$get_stores = $dbh->prepare("SHOW COLUMNS FROM products_active WHERE field REGEXP '^store'");
    $get_stores->execute();
    $stores = $get_stores->fetchAll();

    $update_string = "";
    $first_store = true;
    foreach($stores as $store) {
        if(!$first_store) {

            $update_string .= ", ";

        } else {

            $first_store = false;

        }
        $update_string .= $store['Field']." = '".$status."'";

    }

    $update_activity = $dbh->prepare("UPDATE products_active SET $update_string WHERE product_id = ?");
    $update_activity->execute(array($product_id));

You can not do like this store_% - it is nonexistent column in table as it is written in your error.

You should get all colums with names like /^store_/ (regexp). And than update all this fields having listed them.

mysql> SHOW COLUMNS FROM products where field REGEXP '^store_'

Than collect all fields from 'Field'... You can read more how to get all columns here.
