Answer 1

DECLARE @number1 INT, @number2 INT

SET @number1 = 1

SET @number2 = 867

-- Without the 'RTRIM', the value returned is 3__ !!!

SELECT RIGHT('000' + RTRIM(CAST(@number1 AS NCHAR(3)), 3 )) AS NUMBER_CONVERTED

-- Without the 'RTRIM', the value returned is 867___ !!!

SELECT RIGHT('000000' + RTRIM(CAST(@number2 AS NCHAR(6)), 6 )) AS NUMBER_CONVERTED
