RAND和兩人之間的數字

Question

我需要創建一些隨機數據，它是所有順順當當，直到我notiched我蘭德職能的結果帶回0，是有變化的100 * RAND（）不包括的一種方式0和3 * RAND（）不包括0或者，我需要的是1至100（包括100）和另一個之間，以隨機化編號1和2。

DECLARE @OrderNumber varchar (30) 
DECLARE @OrderDate int 
DECLARE @OrderLineNumber varchar(50) 
DECLARE @CustomerSkey int 
DECLARE @ProductSkey int 
DECLARE @OrderMethodSkey int 

SET @OrderNumber = 1 
SET @OrderDate = 0 
SET @OrderLineNumber = 1 
SET @CustomerSkey = 1 
SET @ProductSkey = 1 
SET @OrderMethodSkey = 1 

WHILE @OrderNumber <= 100 
WHILE @OrderDate <= 100 
WHILE @OrderLineNumber <= 100 
WHILE @CustomerSkey <= 100 
WHILE @ProductSkey <= 100 
WHILE @OrderMethodSkey <= 100 



BEGIN 
INSERT INTO Orders 
(OrderNumber 
, OrderDate 
, OrderLineNumber 
, CustomerSkey 
, ProductSkey 
, OrderMethodSkey) 

SELECT 
'ORD' + Right ('000000' + CAST (@OrderNumber AS varchar (30)), 6) 
,DATEADD (day, CAST (RAND() * 1500 as int), '2008-1-1') 
,(Right ('0' + CAST (@OrderLineNumber AS varchar (30)), 6)) 
,100*RAND() 
,100*RAND() 
,2*RAND() 

SET @OrderNumber = @OrderNumber + 1 
SET @OrderDate = @OrderDate + 1 
SET @OrderLineNumber = @OrderLineNumber + 1 
SET @CustomerSkey = @CustomerSkey + 1 
SET @ProductSkey = @ProductSkey + 1 
SET @OrderMethodSkey = @OrderMethodSkey + 1 

END 

Answer 1

由1只是減少乘法器和加1算賬：

(99 * RAND()) + 1 

和

(2 * RAND()) + 1
