Is this good enough for database connection?

[MySQL_Narb]

Will this code (not including XSS) prevent all malicious changes/deleting in a database, such as SQL Injection? I just want to be sure this code is the best I can make it.

 

/*
     * @METHOD  processInsertQuery
     * @DESC    prepares a query for use, then runs it
     */
    
    
    
    public function processQuery($query, array $binds, $fetch)
    {
        $query_handle = $this->dbc->prepare($query);
        if(!$query_handle->execute($binds))
        {
            $error = $query_handle->errorInfo();
            echo $error[2];
}
        
        //update insertId var
        $this->insertId = $this->dbc->lastInsertId();
        
        //incase we ever want to get the number of rows affected
        //we set our row_count variable to the number of rows
        //affected
        $this->row_count = $query_handle->rowCount();
        
        if($fetch == true)
        {
            return $query_handle->fetchAll();
        }
    }
