Random Number
Apr 15, 2002Generates a true random number from xxx to zzz. Uses a table variable so it all depends on the boundaries you specify how long it will take.
create procedure random_number
@lower int = 0,
@upper int = 256,
@number int = null output
as
set nocount on
declare @numbers table (number_id int identity(1,1), value int)
if @lower > @upper
begin
set @number = @lower
set @lower = @upper
set @upper = @number
end
set @number = rand((datepart(mm, getdate()) * 100000) + (datepart(ss, getdate()) * 1000) + datepart(ms, getdate()))
while (select count(*)
from @numbers) < (@upper - @lower + 1)
begin
insert into @numbers (value)
select (@upper - @lower + 1) * rand() + @lower
end
select @number = value
from @numbers
order by newid()
go
Random Number
Oct 8, 2005I need to update an integer column in my table with a random number. Here's what I've done so far (with the table name and column names changed):
UPDATE dbo.MyTable
SET Column1 = RAND() * 1000000
My question is, how come the values in my column all have the same value? I thought the RAND function gives out a random number? How can I update my table to generate random numbers?
Thanks in advance.
Update To A Random Number?
Nov 27, 2004Hi,
How can I update my users table and set the password field to a random number or string.
eg.
update tbl_users set password='a way to generate a random number say between 2000 and 100000 for example'
even better would be a randomly generated alphanumeric string.
All help much appreciated.
Cheers,

Random Number Generator
Sep 28, 2007In a Name table, I need to generate unique 6 digit random numbers in a field called UniqueID for all records that have the ID field populated.
I will need to run this script periodically. It is critical that any prevoiusly assigned UniqueIDs do not change and only fields that have an empty UniqueID field are updated. I need to preserve the historical mapping of the existing IDs to the ongoing assignment of UniqueIDs.

Generate Random And Unique Number Within Sql ?
Dec 11, 2007I need to generate a random 10 digit alphanumeric string that is also unique within a table. My application will be calling a stored procedure to insert this number into the table. This number will be associated with a id from another table. Is it better to generate the random number within sql (and perform the lookup at the same time), then just pass the number back to the calling application ?
If the calling application generates the number, it will also need to make a call to check if its unique. So im thinking it would be best to simply have sql generate this random number, check the number against the table and then insert the new record.
thoughts ?
Transact SQL :: Set Unique Random Number
Dec 1, 2015Lets say we have a table (tblProducts)
ID  Item           RandomNumber
-------------------------------------------
1Â Â Â JEANSÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 1234567
2Â Â Â SHIRTÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 72813550
3Â Â Â HOODÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Null
4Â Â Â TROUSERÂ Â Â Â Â Â Â Â Â Â Â Â Â 72191839
5Â Â Â BLAZERÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 0
I want to perform a query so that SQL should look for RandomNumber Values and set a Unique Random Number Where RandomNumber Value is Null or 0.So I have got a solution as one of the MSDN Member shared the below query
select id,item,RandomNumber=Case when RandomNumber=0 then (select floor(rand()*100000000-1))
when RandomNumber is null then (select floor(rand()*100000000-1))
else RandomNumber end from tblProducts
So, can you all confirm me, that performing this query ensures that if a Value is assigned to one of the Item in RandomNumber Column, that value will not be assignend to any other Item in RandoNumberColumn.
Random Number Procedure Problems!
Sep 7, 2006Hey Guys, I have a quick stored
procedure question for you. I created a procedure that returns a randomly
generated number.
I know there is a built in
Rand() function but I need to be able to
specify the range. Anyways, it€™s returning multiple numbers (1 for each row in
the tempTable)
But I just want one number returned.
I tried using MAX( ) but that€™s not a good way of doing it.
My question is, how do I return just
one record or number?
Thanks

Returning Random Records And NOT Similar (random Questions)
Jul 20, 2005Hi,I need to extract randomly 5 records from the table "Questions". Now I useSELECT TOP 5 FROM Questions ORDERBY NEWID()And it works. The problem is that I need an additional thing: if SQLextracts record with ID=4, then it should not extract record with ID=9,because they are similar. I mean, I'd like something to tell SQL that if itextracts some questions, then it SHOULD NOT extract other ones.How can I do it?Thanks!Luke

Limitations In Term Of Number Of Tasks And Number Of Columns
Jun 5, 2007Hi,
I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.
To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow.
I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.
Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.
Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?
If not, then do you have any idea why it's so slow ?
Thanks in advance for any answer.

DTS Bug? (or Random Feature?)
Jul 16, 1999Has anyone noticed that if you created DTS package and try to
change connection properties (i.e. change DSN or redirect
DTS to different server or Database), as soon you click OK
it does not save new password and hence does not work
anymore. In my case to move Database from Development to
Production server I would have to recreate all DTS packages.
Is there any way around it?
Any ideas greatly appreciated.
Random Numbers.
Jun 22, 2001I am trying to get random numbers to have a unique value for different processes, then I can identify each process. What happens is that I use rand() function without seed, so I got my random numbers, but after shutting down SQLServer and try to get again another random number after booting up, the same series of random numbers is given again and again. So if anyone knows how I can get unique values,even though reseting the server, and using random function or any other method which automatically provides unique values,I'll really appreciate it if you let me know it.
This is the function: select rand()
