CREATE PROCEDURE p_GenerateRandomPassword(@PWD AS VARCHAR(15) OUTPUT)
AS

SET NOCOUNT ON
DECLARE @Count AS TINYINT

SET @Count = 0
SET @PWD = ''

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- Randomize the first 3 letters in uppercase
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
WHILE @Count <= 2
BEGIN
SET @PWD = @PWD + CHAR(ROUND(((90 - 65 -1) * RAND() + 65), 0))
SET @Count = @Count + 1
END

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- Randomize the next 2 letters in lowercase
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SET @Count = 0
WHILE @Count <= 1
BEGIN
SET @PWD = @PWD + LOWER(CHAR(ROUND(((90 - 65 -1) * RAND() + 65), 0)))
SET @Count = @Count + 1
END

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- Randomize add a number

SET @PWD = @PWD + CAST(ROUND(((25 - 1 -1) * RAND() + 9), 0) AS VARCHAR(3))
