[2008] Binary To Hexadecimal (String)?

So the server I am running has a database of players equipment, I am trying to write a program to see if they are hacking by comparing the item requirement with the stats the player has, to do this I need to convert the varbinary(512) column from the SQL Database too a Hexadecimal string, then from that string remove certain parts of it.

Example:This is the hexadecimal code for an item:

0x440047000028000000000000896B4685

the part I need is "4400" numbers (Position 3,4,5,6 from start) I then need to flip these backwards so it reads "0044". I then will compare this itemIDX with a list of items I have set aside that people mainly use this hack for.

So the main things I need help with, are converting varbinary(512) to hexadecimal and then making my program bring a list of accountID's up who are using the hack, here is how the databases are set out:

Account:
Contains account data ONLY
Game:
Contains the Character and Equipment DB

i need to compare the equipmentDB, then return the CharacterID from the equipmentID, compare that ID with the CharacterID in CharacterDB, then extract the accountID then return the account name from the accountDB I don't know how the binary is split up from item too item, although I would imagine, it isn't, i would have thought it just goes onto the next item when the item ends.Although, all the items start with hex string "0x" so this may be the separator!
