Last month it decided not to work, with exactly the same kind of problems the first one had: the end of the wire near the charger box seemed to be broken.

Instead of go out and buy another charger I’ve decided to open it and try to solve the issue. You can view a full photo reportage in my flickr gallery.

The solution was quite simple and after one month and a couple of days it’s still working with no problems.

Imagine you have a field named price and it’s type is VARCHAR (it doesn’t matter why it’s not INT or FLOAT) and you want to use ORDER BY clause so you can list table rows ordered by price value.

It won’t work, since the prices will be listed alphabetically, you may read here how to fix this issue.

If you have a table labeled products, a field labeled price (typed as VARCHAR) and the following values: 1, 2, 3, 7, 8, 53, 47, 32, 99 and 327.

And you perform a query similar to the one below:

SELECT price FROM products ORDER BY price;

The result will be:

1, 2, 3, 32, 327,47, 53, 7, 8, 99

As you can see the product prices are ordered alphabetically to fix this you should add + 0 to the query (see example below):

SELECT price FROM products ORDER BY price + 0;

The result will be:

1, 2, 3, 7, 8, 32, 47, 53, 99, 327

Problem solved, now your rows will be sorted by price correctly.
