mysql get first letter of a column from a table

Let’s say you have a store table in your database and you want to get the first letter of each store’s name. So you can create a menu by first letter of each store name and not having a letter that contains no stores.

$stores = $this->Store->find('all',array(    'order'=>'name ASC',
'fields'=>'DISTINCT(UPPER(LEFT(name,1))) AS letter',
'conditions'=>array("UPPER(LEFT(name,1)) REGEXP '[A-Z]'")));

excel to mysql import script

Sometimes a client requires you to import some data from an excel sheet to mysql. You can do it by hand if there are only a few records. However, if there are a few hundred records, you need some kind of script to do this. I had this same problem. So i wrote something in autoit and thought i might share it. The script itself it very simple and very easy to modify.
You need to download and install autoit before you can run this. I could just give you the executable, but no one would download it and no one should. Besides the script is very specific and is meant to be modified to suit your need.

here the file in case wordpress butchers my script.
