Bug description:Mysql relative seek
Description:
------------
There is currently a function to do absolute seek in Mysql API.
When you need to to relative seek , you have to implement integer counter
to keep track of the current cursor position. Then call seek
here is a sample code:
//iterating over rows
for/while....{
mysql_fetch_xxxx(....);
$current_row++;
[...]
// call relative seek
$current_row+= $seek_offset;
mysql_data_seek($id, $current_row);
This quite simple but when the code gets complicated, it s easy to miss on
$current_row update. The only only solution is to encapsulate php mysql
function in additional abstraction layer to handle counter updates safely.
I suppose the internal counter is already available in mysql module.
What I am suggesting, is to expose this internal counter by adding a new
function to mysql API.
