T-SQL Format integer to 2-digit string - tsql

Question

I can't find a simple way to do this in T-SQL.
I have for example a column (SortExport_CSV) that returns an integer '2' thru 90.
If the stored number is a single digit, I need it to convert to a 2 digit string that begins with a 0.
I have tried to use CAST but I get stuck on how to display the style in the preferred format (0#)
Of course it is easy to do this on the front end (SSRS, MSAccess, Excel, etc) but in this instance I have no front end and must supply the raw dataset with the already formatted 2 digit string.

Answer 1

select right ('00'+ltrim(str( <number> )),2 )

Answer 2

You can use T-SQL's built in format function:
declare #number int = 1
select format (#number, '0#')

Answer 3

SELECT RIGHT('0' + CAST(sortexport_csv AS VARCHAR), 2)
FROM your_table

Answer 4

You're all doing too much work:
right(str(100+#x),2)
-- for a function, same idea:
--
create function zeroPad( #yourNum int, #wid int)
as
begin
return right( 1000000+#yourNum), #wid)
end

Answer 5

Convert the value to a string, add a zero in front of it (so that it's two or tree characters), and get the last to characters:
right('0'+convert(varchar(2),Sort_Export_CSV),2)

Answer 6

DECLARE #Number int = 1;
SELECT RIGHT('0'+ CONVERT(VARCHAR, #Number), 2)
--OR
SELECT RIGHT(CONVERT(VARCHAR, 100 + #Number), 2)
GO

Answer 7

Here is tiny function that left pad value with a given padding char
You can specify how many characters to be padded to left..
Create function fsPadLeft(#var varchar(200),#padChar char(1)='0',#len int)
returns varchar(300)
as
Begin
return replicate(#PadChar,#len-Len(#var))+#var
end
To call :
declare #value int; set #value =2
select dbo.fsPadLeft(#value,'0',2)

Answer 8

You could try this
SELECT RIGHT( '0' + convert( varchar(2) , '0' ), 2 ) -- OUTPUTS : 00
SELECT RIGHT( '0' + convert( varchar(2) , '8' ), 2 ) -- OUTPUTS : 08
SELECT RIGHT( '0' + convert( varchar(2) , '9' ), 2 ) -- OUTPUTS : 09
SELECT RIGHT( '0' + convert( varchar(2) , '10' ), 2 ) -- OUTPUTS : 10
SELECT RIGHT( '0' + convert( varchar(2) , '11' ), 2 ) -- OUTPUTS : 11
this should help

Answer 9

here you go
select RIGHT(REPLICATE('0', 2) + CAST(2 AS VARCHAR(2)), 2)
should return 02

Answer 10

try
right('0' + convert(varchar(2), #number),2)

Answer 11

Another example:
select
case when teamId < 10 then '0' + cast(teamId as char(1))
else cast(teamId as char(2)) end
as 'pretty id',
* from team

Answer 12

Try this
--Generate number from 2 to 90
;with numcte as(
select 2 as rn
union all
select rn+1 from numcte where rn<90)
--Program that formats the number based on length
select case when LEN(rn) = 1 then '00'+CAST(rn as varchar(10)) else CAST(rn as varchar(10)) end number
from numcte
Partial Output:
number
002
003
004
005
006
007
008
009
10
11
12
13
14
15
16
17
18
19
20

Answer 13

SELECT
replace(str(month(DATEADD(month, -1, '2012-02-29')), 2),' ' , '0')

Answer 14

You can create a function like this:
CREATE FUNCTION [dbo].[f_convert_int_to_2_digits](#input int)
RETURNS varchar(10)
AS
BEGIN
--return value
DECLARE #return varchar(10)
if #input < 10
begin
set #return = '0' + convert(varchar(1), #valor)
end
else
begin
set #return = convert(varchar(10), #input)
end
-- return result
RETURN #return
END
and then use it everywhere:
select [dbo].[f_convert_int_to_2_digits](<some int>)

Answer 15

Example for converting one digit number to two digit by adding 0 :
DECLARE #int INT = 9
SELECT CASE WHEN #int < 10
THEN FORMAT(CAST(#int AS INT),'0#')
ELSE
FORMAT(CAST(#int AS INT),'0')
END

Answer 16

DECLARE #Number int = 1;
SELECT RIGHT('0'+ CONVERT(VARCHAR, #Number), 2)
--OR
SELECT RIGHT(CONVERT(VARCHAR, 100 + #Number), 2)
GO

Answer 17

The simplest way is:
declare
#len int = 10,
#number int = 122222,
#prefix char = '0'
select replicate(#prefix, #len - len(#number)) + CAST(#number AS VARCHAR)
result:
0000122222
