Laravael4 db raw query using ON DUPLICATE KEY UPDATE drops error - mysql

Question

I'm really fighting with a laravel ON DUPLICATE KEY UPDATE query I can't get it to work, so the query basically looks like
foreach ($queries as $query) {
$update_time = array('update_time' => date('Y-m-d H:i:s'));
$query = array_merge($update_time, $query);
$keysString = implode(", ", array_keys($query));
$indexes = "";
$values = "";
$updates = "";
foreach ($query as $i=>$v){
$values .= ':'.$v.',';
$updates .= $i.'="'.$v.'",';
}
//$holder = rtrim(str_repeat('?,', count($query)),',');
$updates = rtrim($updates,',');
DB::statement("INSERT INTO products ({$keysString}) VALUES ({rtrim($values,',')}) ON DUPLICATE KEY UPDATE {rtrim($updates,',')}")
}
but I get
SQLSTATE[HY093]: Invalid parameter number: mixed named and positional parameters
How do I make a prepared statement in laravel4 for raw queries?

Answer 1

By default Laravel binds its data using ? and you are binding your data with :foo, meaning there is a mixture of the two approaches and PDO is getting sad about it.
PDO: Invalid parameter number: mixed named and positional parameters
Something like this should get you going in the right direction:
foreach ($queries as $query) {
// Add the update time without merging stuff
$query['update_time'] = date('Y-m-d H:i:s');
// How many bits of data do we have
$bindingCount = count($query);
// Same as before, just get the keys
$keyString = implode(", ", array_keys($query));
// Start off a bindings array with just the values
$bindings = array_values($query);
$updates = [];
foreach ($query as $field => $value){
$updates[] = "{$field} = ?";
$bindings[] = $value;
}
$valueString = implode(',', array_fill(0, $bindingCount, '?'));
$updateString = implode(',', $updates);
DB::statement("INSERT INTO products ({$keyString}) VALUES ({$valueString}) ON DUPLICATE KEY UPDATE {$updateString}", $bindings);
}
