Hello,
for instance, there is a query
$update_timestamp_query = "update $register
set $register_table_iteration_timestamp_field_name = now()
where $register_table_id_field_name in (" . implode(',', $identifiers) . ");";
Calling
$update_timestamp_query = $db->prepare($update_timestamp_query);
and executing the query
$db->query($update_timestamp_query)
yields MySQL error since there're \n symbols in the SQL query output.
