i have a column in a database in varchar format, but the content is only numbers.
I cant change the column to int format, and need to use the varchar format.

How it possible to find the highest number?

```
Category
-------
1
2
3
4
5
6
7
8
9
10
11
12

```

if I use this

```
SELECT * FROM [Navision4].[dbo].[" & strCompany & "$eShopCategory] 
ORDER BY Category desc

```

it my output 10, but i want the output to be 12.
