Question

I am using a phpdao for my database operation.
When I run this code there is a error

function queryByContentAndCreatedBy($city,$min,$max){
    $sql = "SELECT id FROM users WHERE city=? LIMIT ?,? ";
    $sqlQuery = new SqlQuery($sql);
    $sqlQuery->setString($city);
    $sqlQuery->setNumber($min);
    $sqlQuery->setNumber($max);
    return $this->executeUpdate($sqlQuery);
} 

public static function executeUpdate($sqlQuery){
    $transaction = Transaction::getCurrentTransaction();
    if(!$transaction){
        $connection = new Connection();
    }else{
        $connection = $transaction->getConnection();
    }       
    $query = $sqlQuery->getQuery();
    $result = $connection->executeQuery($query);
    if(!$result){
        throw new Exception(mysql_error());
    }
    return mysql_affected_rows();       
}

Connection.php

public function executeQuery($sql){
    return mysql_query($sql, $this->connection);
}

Then there is a error :

You have an error in your SQL syntax ... near ('Pu\'m','d\'Artagnan','s\dsd') at line 1

Similar error is for this query

 $sql = "SELECT id FROM users WHERE city IN (?,?)";

In PDO this is a solution : see details

$dbh->setAttribute( PDO::ATTR_EMULATE_PREPARES, false ); 

Whats is a equivalent solution for this for my dao ?

Answer 1

you are doing it wrong.
and solution from the linked question won’t help you.

if your “phpdao” doesn’t have a setArray() method, you have to create the query manually.

1. Create a string that looks like (?,?,?,?,?,?) where number of ?s is equal to the number of members of your array.
2. add this string into your query
3. bind your array members in a loop.
