Im trying to write a statement that only selects one of the possible rows that could be given.
For example:
Car ID: Colours Available:
1 Blue
1 Green
1 Black
I want the statement to return:
Car ID: Colours Available:
1 Blue(Random Selection)
Is this possible?
Thanks

View 5 Replies View RelatedI have three tables that are joined together to retrieve a piece of data.Table One has the columns pid1(PK), idTable Two has the columns pid1, qid1, idTable three has columns qid1, question, answerHere is my sql statement:SELECT Table1.pid1, Table2.qid1, Table3.Question FROM Table1 JOIN Table2 ON Table1.pid1=Table2.pid1 JOIN Table3 ON Table2.qid1=Table3.qid1 WHERE Table1.pid=...(N)I put an elipsis because I'm stuck on how to proceed from here. See I need to randomly select a value from column pid1 in table1 then use this value to replace N in the sql statement, then have the statement run and randomly return exactly one piece of data instead.Is this possible? How can you randomly get one piece of data from joining three table without a WHERE CLAUSE.

I need to select a random record from TABLE. It might look easy with using RAND() function, but the tricky part is that ID's which are the PRIMARY KEY, were assigned as a random number.
So right now ID's in that TABLE look some thing like that: -18745, 45809, 129, -5890023, 487910943, -209, etc...
If any one have any ideas please respond.
Thanks in advance.

SELECT * FROM QuestionMaster.
I tried to use the following statement to get the random records but I can't get the value in the variable out of this statement that I can use in my above select statement. Please HELP.
SELECT Convert(int,RAND()*97)
Thanks in a million.

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
View 1 Replies View RelatedI'm using ASP and SQL Serv 2000. What I need to get from 2 tables (company & customers) is random 10 customers from random 20 comp.
Anyone got an idea how to do this??? I've spent 2 days trying to get stored proc. or T-SQL to work, but nothing good came out of it. I can get 1 comp and 10 cust, but not a grouped list of 20 comp. w/ 10 cust. each.
Help is greatly appreciated.
I've got a big problem that I'm trying to figure out:
I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like:
[AddressID] [int]
[LocationID] [int]
[Type] [nvarchar](10)
[Address] [varchar](50)
[City] [varchar](50)
[State] [char](2)
[Zip] [varchar](5)
[AddDate] [datetime]
[EditDate] [datetime]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table.
So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
Thank you in advance for any and all replies...

FROM mytable
ORDER BY recrand
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.
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
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.

How can I have display random value for field varchar(10).
View 5 Replies View RelatedI 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

How Can I select a Random set of records from a database table?
View 3 Replies View RelatedI 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

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.

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
