Sorting a Nullable Biginit is returning wrong sorted data

Question

I have a column inside my sql server 2008 R2 of type Biginit that allow nulls named “Serial”. It has values such as :-:-

**Serial**
100200
100202
100375
100376
100377

Now inside my asp.net mvc web application, I have the following linq query inside the entity framework :-

var records = repository.AllFind(withOutSpace).OrderBy(a => a.Technology.Serial).ToPagedList(page, pagesize);

so I am ordering the the records ascending based on the Serial number , but the result was that I got the following order

100375
100376
100377
100200
100202

So it assumed that 100200 is grater than 100377 !!, any idea what might be causing this issue ? Thanks

Answer 1

If it is taking 100200 as bigger than 100377 then, he is sorting lexicographically, like if the elements were string.

Lexicographycally, 100200 is greater than 100377, and maybe this is the reason.
