Currently I am using the following to take an integer and create a 6 character number with leading 0's but really need a shorter method/function.
REPLICATE(0, 6-len(CONVERT(varchar(6), integerfield1))) + CONVERT(Varchar(6), integerfield1)
to create a character field of
000001 for the value of 1 and
000010 for the value of 10 and so on...
Is there a shorter method/function for creating these results.
I absolutely need it to be a left justified number with leading zeroes because i and concatenating a string, number, sting and comparing it to a given string.

How about this, not sure how short you want it

DECLARE @Int AS INT

SET @Int = 1

SELECT RIGHT(REPLICATE('0', 6) + CAST(@Int AS VARCHAR(6)), 6)

Even shorter:

DECLARE @Int AS INT

SET @Int = 1

SELECT RIGHT('00000' + CAST(@Int AS VARCHAR(6)), 6)

Nice.. I almost did it without the REPLICATE() function. Always felt it was more typing than needed.

There is something wrong with a convenience function to make duplicates of a sinlge character that takes 12 extra characters to do it. For anything less than 13 copies of a character, you might as well just type it in as a literal.

Short? You guys need to try harder. :satisfied:

select

NewNum = right(1000000+MyNum,6)

from

( --Test Data

select MyNum=1union all

select 10union all

select 100union all

select 1000union all

select 10000union all

select 100000union all

select 999999 ) a

Results:

NewNum

------

000001

000010

000100

001000

010000

100000

999999

HA! Short indeed.. but the post asked for a character based result. But koodos if the string data type is not really needed.

Thank you for that. I am using a 4GL language and they only allow me 300 characters for my part of the query. So when i have 3-5 selection criterias i usually have to decide which ones to leave out. This will help tremendously....

Can you write stored procedures and/or functions on the database?

We can write functions/stored procedures but the problem comes from the 4GL Language.

THEY issue a query command (SELECT ..... WHERE... ) and we are only allowed to add to the where clause. Plus I am limited to just 300 characters. Most of my selection criteria is for ranges of values. strings, dates, integers. But on some of the selection routines it involves 3 fields in multiple tables

F1 Char(4), F2 Integer, F3 Integer. through our programs we limit F2 to max size of 6 digits (999999) and F3 to 2 digits (99). So wen i put those into my where clause with the big replicate command i pretty much ate up the 300 characters.

F1+F2(6)+F3(2) in (select F1+F2(6)+F3(2) from Table2 where F4 = ...) or

F1+F2(6)+F3(2) >= '{programed start value (string)}' and F1+F2(6)+F3(2) <= '{programmed end value (string)}'

So any thing i could do to shorten it helps.

You do realize that the RIGHT function returns a string?

My code simply takes advantage of the fact that the integer expression is automatically cast to a character string.

From SQL Server 2000 Books Online:

[font="Arial Narrow"]RIGHT

Returns the part of a character string starting a specified number of integer_expression characters from the right.

Syntax

RIGHT ( character_expression , integer_expression )[/font]

CAST Integer to Character with leading zeroes
