Random Number Procedure Problems!

Sep 7, 2006

Hey 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
Fellas,

Chris


ALTER PROCEDURE
dbo.spx_GetRandomNum

AS

DECLARE @Start_Num int

DECLARE @End_Num int

DECLARE @ReturnValue
int
DECLARE @RecNum
int
DECLARE @CurrentRec
int
DECLARE @MyCount
int

SET @Start_Num=1

SET
@End_Num=100


CREATE TABLE #tblTemp (CurrentRecNo
int IDENTITY(1,1), RandomNumber int null)

SET @MyCount = ( @End_Num -
@Start_Num ) + 1
SET @CurrentRec = 1


WHILE @CurrentRec <= @MyCount


BEGIN
SET @RecNum
= CAST((RAND() * @MyCount) AS int) + @Start_Num

INSERT INTO
#tblTemp (RandomNumber) VALUES (@RecNum)
SET
@CurrentRec = @CurrentRec + 1

END

SET
@ReturnValue = (SELECT RandomNumber FROM
#tblTemp)

DROP TABLE #tblTemp


RETURN

Random Number

Apr 15, 2002

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

Random Number

Oct 8, 2005

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.

Random Number Generator

Sep 28, 2007

In 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.

Regards,

Generate Random And Unique Number Within Sql ?

Dec 11, 2007

I 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, 2015

Lets say we have a table (tblProducts)

ID   Item             RandomNumber
-------------------------------------------
1    JEANS                      1234567
2    SHIRT                    72813550
3    HOOD                             Null
4    TROUSER               72191839
5    BLAZER                              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.

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

Variable Number Of Where Clauses In A Stored Procedure

Jun 20, 2001

I have a web page which passes back parameters to a stored procedure.
From the web page the user selects different clauses for the 'where' criteria.
Based upon the number of clause items in the parameters sent back, a select statement is built and executed.
In the stored procedure I have many if statements to chose the correct sql statement.
As the no of clauses in the where statement can vary, it can become messy script.
Has anyone dealt with this scenario. What is the best strategy ?

A simple illustation of this is as follows
A statement with two clauses :-

Select * from Sales where
user = 'John' and country = 'England'
A statement with three clauses :-
Select * from Sales where
user = 'John' and country = 'England' and County = 'Staffordshire'

The stored procedure would except three parameters and would build a string based on the number of actual where clases sent back

Variable Number Of Arguments In A Stored Procedure

May 5, 2008

Can a Sql Server SP have variable number of arguments??? If yes, can somebody point me to a resource demonstrating that??? I need to send variable number of arguments to some of my SPs & iterate them with either foreach or traditional for loop. Any support would be greatly appreciated.

If variable number of arguments are not feasible, then can I pass them as an array to the SP (again a Sample code would be desirable)???

Limit The Number Of Records Returned In Stored Procedure.

Aug 17, 2007

In my ASP page, when I select an option from the drop down list, it has to get the records from the database stored procedure. There are around 60,000 records to be fetched. It throws an exception when I select this option. I think the application times out due to the large number of records. Could some tell me how to limit the number of rows to be returned to avoid this problem. Thanks.

Stored Procedure - Variable Number Of Parameters For Search

Dec 4, 2003

Hi,
I have a repeater control which I populate with search results from SQL Server.

But I can't figure out how to cope with users who submit multiple search items and still use my stored procedure. Is this possible or do you have to build the query with a StringBuilder and execute it manually?

I'm using a stored procedure with parameters:

input parameters <-- PageSize & CurrentPage
output parameter --> TotalRecords

Am using a temporary table to store all records before Select-ing those required for the particular page.

If I compose the query manually then I can't figure out how to get TotalRecords back as a return parameter. Would appreciate help on this one.

Am hoping that stored procedures can cope with an unknown number of parameters.

Passing In Variable Number Of Parameters To A Stored Procedure

Jul 9, 2006

I am fairly new to MSSQL. Looking for a answer to a simple question.

I have a application which passes in lot of stuff from the UI into a stored procedure that has to be inserted into a MSSQL 2005 database. All the information that is passed will be spilt into 4 inserts hitting 4 seperate tables. All 4 inserts will be part of a stored procedure that have to be in one TRANSACTION. All but one insert are straight forward.

The structure of this table is something like

PKID
customerID
email address
.....

customerID is not unique and can have n email addresses passed in. Each entry into this table when inserted into, will be passed n addresses (The number of email addresses passed is controlled by the user. It can be from 1..n). Constructing dynamic SQL is not an option. The SP to insert all the data is already in place. Typically I would just create the SP with IN parameters that I will use to insert into tables. In this case I can't do that since the number of email addresses passed is dynamic. My question is what's the best way to design this SP, where n email addresses are passed and each of them will have to be passed into a seperate insert statement? I can think of two ways to this...

Is there a way to create a variable length array as a IN parameter to capture the n email addresses coming in and use them to construct multiple insert statements?

Is it possible to get all the n email addresses as a comma seperated string? I know this is possible, but I am not sure how to parse this string and capture the n email addresses into variables before I construct them into insert statements.

Any other ways to do this? Thanks

I matched my parameters to my procedure to what I define as the parameters list, but somehow I keep getting a too many parameters specified.

If I had control over it in C# it would be easy to select which params are actually being sent, but I would like to give a procedure name to call and I can log the parameters sent somewhere.how to do.

Transact SQL :: Using Number Of Days As Stored Procedure Parameter

Aug 7, 2015

We have a stored procedure which currently accepts the following parameter: exec dbo.PurgeOldData <'yyyy-mm-dd'...We want to schedule this sp to run once a (first day of the month) going back to say today's date (or the date when this sp is called to run) minus 365 or purging 12 months data. Basically, the function should convert the today's date minus xxx number of days to yyyy-mm-dd so that the sp accept it as the correct parameter and purges the data successfully. So, if the sp is run on 2015-08-06, it will purge data going back to 2014-08-06 or earlier with the following parameter:

exec dbo.PurgeOldData <'2014-08-06'>

which means, all the data prior to the above date will be purged. Even the sp was run on 2015-08-06, the converted value of 2014-08-06' is entered as the sp parameter.
