Web Forms :: Generate A Unique Identifier Or Reference Number Based On A Format?

Jan 22, 2010

I need to generate a Unique Reference number that has 7 digits.

It should be formatted in the following way:

1st: B (Ball), G (Gift), C (Cat)

2nd: represents year of booking A(2010), B(2011),C(2012), etc

3rd: represents the month of booking J(Jan),F(Feb),M(Mar),A(Apr),Y(May), U(Jun), L(Jul),G(Aug), S(Sep),O(Oct),N(Nov),D(Dec)

4th: days of booking A(1st) - Z(26th), 1(27th) - 5(31st)

5,6,7th: These are counters for the number issues each day. Each can be A-Z,0-9 giving a total of 46,656 combinations. So 0 is first, then 1, 2, 3, 4, 5, 6, 7, 8, 9, A-Z, then 00 to 0Z, then 10 to 1Z, then 20 to 2Z, etc

Now , the 1st Digit is a Character that I generate based on a condition and that shouldn't be a problem.

C# - How To Generate A Transaction Number

Dec 9, 2010

I was thinking of formatting it like this

(1 character + 19 digits)


T is type
YYYY is year
MM is month
DD is day
N is sequencial number
X is check digit

The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not.

EDIT can I have the sequencial number resets itself after 1 day (24hours).

P201012080000000001X <-- first
transaction of 2010/12/08
P2010120810000000002X <--- second
transaction of 2010/12/08
P201012090000000001X <--- First
transaction of 2010/12/09
(X is the check digit)
