This is my stored procedure..here i have a parameter of variable @MaxLength where i pass the value like 2 or 3 or 4 and depends upon the need.
if i pass 2, the @DecNumber would start from 10 and gets incremented(SET @DecNumber = @DecNumber + 1) up to the total row count
so obviously if the row count exceeds 99, it would go to 3 digit values like 100,101,102 and so on...
my problem is if the @maxLength is 2, at any cost it should maintain distinct two digit values in a sequence...like 0 to 99 and instead of 100 it could be A1 ,A2,A3.....A9, B1....B9,C1..C9 and so on...
i am not asking that i really want this kinda sequence..it may be any kinda sequence only with 2 digits...
I know this question may look odd..but this is my situation..so please help me friends...
Thanks,
Charmer

The first problem is that @DecNumber is a BIGINT. You cannot store characters in BIGINT. First you need to change this to CHAR(2) or something that applies. Does the sequence matter? Can it start at AZ and then go to YD? Or are you eventually going to order this?

ok i will change the data type...sequence is not important....maintaining with unique 2 digit values or 3 digit depends upon the need...it must fit for some large row counts(maximum 2000)...

Can you create a tally table with these values (if maximum is 2000, I would create 3000 just in case)?

sorry friend,What is a tally table? i don't have much knowledge with SQL... if you give me an example , i would try to create that one...

Something similar to this:

CREATE TABLE decNumber (decNumberCount tinyint, decNumber VARCHAR(3))

INSERT INTO decNumber

SELECT 2, '99'

UNION ALL

SELECT 2, 'A0'

UNION ALL

SELECT 2, 'A1'

UNION ALL

SELECT 3, '001'

UNION ALL

SELECT 3, '999'

UNION ALL

SELECT 3, 'A00'

UNION ALL

SELECT 3, 'A01'

In this case, decNumberCount = number of characters and decNumber will be what you will assign. Obviously this needs more rows inserted, but you should get the general idea.

Careful with using tinyint here in this case...it doesn't go up to 3000! ::-D

🙂 but this is indicating hw long the decNumber is. The requirement says that it can be 2 or 3 characters.

The easiest and most elegant way to achieve what you ask is to implement 36-based encoding. I have no time today to show how it can be done in T-SQL, may be tomorrow, or just google implementing n-based encoding you might find something on it.

But it will not work exactly as you want it will not go like:

18

19

20

21

...

99

0A

But like that:

18

19

1A

1B

...

1Z

20

21

...

99

9A

9B

...

ZZ

100

101

...

And so on...

See the following article. If you study it until you understand it, it will change your life insofar as T-SQL goes especially if you can see the possibilities beyond what is in the article.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

here i have a parameter of variable @MaxLength where i pass the value like 2 or 3 or 4 and depends upon the need.

You give an example of "like 2 or 3 or 4"... Can that number be larger depending "upon the need"?

yes ..it may be anything between 1 to 9

if it is 1 then it must be unique 1 digit or 1 char value to the total number of rows...

if 2 = 2 digit or 2 char values, 3 = 3 digit or 3 char values and so on....

i don't want in a sequence order...i just want unique values...maintaining unique 1 digit or 1 char value if length is specified as 1 to the total count...and 2 digit or 2 char values if length is specified as 2 and so on...
