Random Number Generation in SQL Server

Question

I Need to generate a random number between two numbers for each row.

For Eg:

select ColName, (Random nos between 1500 to 2000) from TableName

Thanks in advance

Answer 1

Random number formula is

RANDOM DECIMAL RANGE

SELECT RAND()*(b-a)+a;

Example

SELECT RAND()*(25-10)+10; // Random between 10 to 25 

RANDOM INTEGER RANGE

SELECT FLOOR(RAND()*(b-a)+a);

Example

SELECT FLOOR(RAND()*(25-10)+10);

Answer 2

DECLARE @start INT
DECLARE @end INT

SET @start = 1500
SET @end = 2000

SELECT  Round(( ( @end - @start - 1 ) * Rand() + @start ), 0)

Update : To get random number for each row.

select ABS(Checksum(NewID()) % (@end-@start)) + @start

Answer 3

a little change required, by replacing the following code it will respond.

 Round(( ( @end - @start - 1 ) * Rand(checksum(newid())) + @start ), 0)

Eg:

Generate Same Value :

select top 10 ROUND(((2000 - 1500 -1) * RAND() + 1500), 0) from sysobjects

Generate Different Value :

select top 10 ROUND(((2000 - 1500 -1) * Rand(checksum(newid()))+ 1500), 0) from sysobjects

Answer 4

SELECT ROUND(((2000 - 1500 -1) * RAND() + 1500), 0)
