Function to Add Leading 0's (Zeros) to an INT

By Joshua A. Walker,

Copy the code. Run the create and there is test script in the comments section you can use for testing.

There is a line commmented out that will limit the maximum size to 100 characters.

 

EX: SELECT dbo.DBA_fnAddLeadingZeros(1234,6)

will return '001234' for a TOTAL length of 6 characters.

 

This is especially helpful in data warehousing where you want to force all numbers to a fixed length such as day = '01' instead of 1... etc...

 

SELECT dbo.DBA_fnAddLeadingZeros(DATEPART(MONTH,GETDATE()),2) [MONTH]
, dbo.DBA_fnAddLeadingZeros(DATEPART(DAY,GETDATE()),2) [DAY]
, DATEPART(YEAR,GETDATE()) [YEAR]
, dbo.DBA_fnAddLeadingZeros(DATEPART(MONTH,GETDATE()),2) [HOUR]
, dbo.DBA_fnAddLeadingZeros(DATEPART(MINUTE,GETDATE()),2) [MINUTE]
, dbo.DBA_fnAddLeadingZeros(DATEPART(SECOND,GETDATE()),2) [SECOND]
