Random Values
Mar 8, 2005
I have a table with 3 fields SiteID (PK), SiteCode, SiteName.
For each SiteCode I have several rows with different SiteName.
For example: 1 327 a
2 327 b
3 327 c
4 328 aa
5 328 bb......
I need to retrieve each time SiteCode with random SiteName.
For example: 327 b , 327 a , 327 c
328 aa 328 bb 328 aa.
I need it very urgent, so any ideas will be very helpful. Thanks to all,

Is there a way to write an SQL statement to choose random values from a particular select statement..for example:
select * from address
I was thinking, if there was a way to use an include statement for it like:
select * from address where id IN ('generates some random values')
thanks in advance

Hi,I like to have a SQL script which could update a table to set one attributeto a random value picked from a given list. The prototyping code is asbelow:select @value_list = ('John', 'David', 'Mathew', 'Paul')....update EMP set emp_name = @random_namewhere ...where random name is randomly got from the given list. Of course there willbe a cursor so that different row may have different random name but notnecessary unique. Also the attribute and the list could be any valid commonSQL data typesThanks!Ximing

For a new project. I need to create random alphanumeric characters as primary key values when inserting a record.
eg: cmSbXsFE3l8
It can start from 4 digit characters and can grow to 6, 7 as required
The database will involve more than 10000 concurrent users.
I don't want to use guid or auto increment integer or sequence.

Hi,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

Has 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.

I 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()
Alberto.

So i've got to generate these queries that go from the first of a one month to the last day of a month. the user provides the starting and ending months.
What I was wondering was is there an easy way to set the last day of the month in sql without having to go in and hard code which months end on the 30 and which ones end on the 31.

I once came across a database in which when ever a row was inserted, a unique random code was also inserted in a column. This code generated was similar to format like {8A5FE5F1-6BDA-476C-A4DB584A7710FBF91121054625}. I was told that SQL2000 has some inbuilt functionality for this.
Any idea on how to do this using SQL2000 or coding.
I feel this is much better than Identity Column as using autonumbers in quesrystring is too much risky as they easily readable.
Please help.
Thanks

I have a customer that wants to be able to generate a random list...
-----------------------
The list is case numbers, and I can get those easy enough by saying
SELECT
dbo.table_case.id_number
FROM
dbo.table_case
Now, what I want to do is take that list and extract 1 out of every 1000, picking out random id_numbers to display.
Is this something I can do via a SQL query?
Thanks,
Dan

Generates 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

I used this to generate a random password. You can change what it returns to up to an 8000 character password if you feel brave. You will need this function (http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=14924) to generate the random numbers. For some reason, occassionaly a NULL (CHAR(0)) character would get in there and mess things up so I had to remove those. You could change this to even include the non alpha numeric characters.
create procedure random_password
@length smallint,
@password nvarchar(256) = null output
as
set nocount on
declare @number int
declare @lower int
declare @upper int
declare @part tinyint
if @length > 256 set @length = 256
set @password = ''
while len(@password) < @length
begin
exec random_number 0, 3, @part output
if @part = 0
select @lower = ascii('a'),
@upper = ascii('z')
else if @part = 1
select @lower = ascii('A'),
@upper = ascii('Z')
else if @part = 2
select @lower = ascii('0'),
@upper = ascii('9')
set @part = null
set @number = null
exec random_number @lower, @upper, @number output
set @password = @password + ltrim(char(@number))
if substring(@password, len(@password), 1) = char(0) set @password = left(@password, len(@password) - 1)
end
go

I 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.

I am new to TSQL and any help on the following would be appreciated.
I have a table that looks like this
security Message
2345 Good
2346 Good
uoas Bad
fsaf More
sdad More
asdd More
ndgs More
I have to pull in a list of distinct messages with a count and any 3 cusips that belong to the message.
I have written, something like this
SELECT MESSAGE_TEXT, COUNT(*) AS Expr1, MIN(security) AS Expr2, MAX(SECURITY) AS Expr3
FROM dbo.DerivedSIACDataMessages
GROUP BY MESSAGE_TEXT
ORDER BY COUNT(*) DESC
However, this lets me pull only 2 securities per message and I want to pull in 4 cusips.
Any help would be apprecioated
Thanks.

Hi all!
I have a table with three columns: Identity, DateTime (current_timestamp) and one which I want to fill with random values always depending on the value in the same column one row above.
Since I want it to be a stored procedure I have to pass three parameters - an initial value, the range within the random number is higher or lower than the number in the preceding row and the number of rows which should be inserted. This means that as soon as a new row is inserted there is also a new seed for the random value for the next line.
My problem now is that I would always get out the same number. Maybe you know a solution for my problem.
Many thanks and greetings from Austria
