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 ?

How To Generate Random Number For The Value In Th
Aug 2, 2007How to create random number for the value in other colum. Please help and urgent
I have a table with 4 column ( ID, Ori_Quantity, Rand_Quantity, Location)
If Ori_quantity < 5000 then
Rand_quanty as qty = I want Random number within 100
Else If Ori_quantity = 0 or < 10 then
Rand_quanty as qty = I want Random number within 7
End if
From tblname where Location = 'DAS'
I have around 2500 field. So when I run the query I expect the result should be
like below
Ori_Quantity, Rand_Quantity

2500 89

Transact SQL :: Set Unique Random Number
Dec 1, 2015Lets 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.

Datepart (to Get 2 Digit Number For The Month)
Apr 28, 2008I want to build a string that contains today's date (without the time).
For example, if select GETDATE() returns 2008-04-28 14:18:34.180, I want to end up with either
(1) 2008-04-28
or
(2) 20080428. (I always want the month to be represented by a 2 digit number)
Is there a datepart parameter that will give me (1) in one shot? I don't think so, since datepart returns an integer and (1) is not in the form of an integer.
So, I was trying to build (2) by using the yyyy, mm, and dd parameters to extract out the appropriate parts and casting them to a string and contatentating them. However, when I do the month portion, (using mm) it gives me the integer that represents the month, and this number can be 1 or 2 digits depending on the month. I always want it to be a 2 digit number. For example, if I'm in Apr, I want to end up with "04", not "4". This would also apply to the day portion. (although the date that I'm writing this post is on the 28th so I'm not certain what GETDATE() will return on dates that are 1 digit.)
The only way I can get the single digit month to write out as a 2 digit month is by doing a LEN() function on the string and if it is a length 1, then concatenate a "0" in front of it. I started doing this and the expression became too crazy, so I wanted to first check to see if someone can come up with something cleaner.
Thanks for looking.
Transact SQL :: 4 Digit Number To Add To Table
Oct 15, 2015I am currently working on an app and have an issue with a table in the database. The table has 10,000 records in it and a column is added that is to use a 4 digit in sequence. The datatype for the new column is varchar since no math will ever be done on the added column. If necessary, I can change the datatype but would prefer not to. The 4 digit would start with 0000 at ID 1 and go to 9999 at ID 10000. I'm thinking some type of update statement since it is updating each record but how would it be done sequentially?

Help!!!!to Generate Random Data....
Jul 8, 2007Dear All,
I have some problems with the assignment from my professor.
Suppose there are two tables storing first names and last names, one table with column of first name and gender, the other with last name.
how to write stored procedures to get a random first name + random last name for Males or Female. like you got a list of all M & F first name and last name, then you try to match first name with any other last name (I believe this is random).
and the task is to write a script so each time when a female or male full name is need, it will return a random name for the requested gender.
I am totally struck and no idea how to deal with it, in fact I am just a beginning in SQL server, and I know there is a stored procedure to generate random number, however, I can't see the use of it here,,,,:eek:
Could anyone help me out ? thanks very much !!!:beer:

May 4, 2006I 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.

How To Generate Random Default Value For A Field Under Sql Table?
Oct 13, 2005hi
I have a field call: password, I want to generates some random chars as
default password for users (so user got something to login, and update
later).
Current Solution I have:
I made myself a trigger and it does generate password on insert, but
the problem with that is I have to allow NULL on that field. I
don't want NULL to be allowed, and if I don't allow null... sql server
won't allow me to insert a record (when leaving password field empty).
Reason i don't wanna allow NULL on that field, is because there may be
more applicaions using the same field from the same database.
Just in case if the other developer gets sloopy, I don't want other
application(s) allow user put to enter a null or leave it blank on my
password field.
My question is:
1) can I put a function or some sort at the "Default" field under "Design Table", if so...how?
2) any suggestions for a better implementation?
3) if (1) doesn't work, what other options would you suggest other then the current trigger i'm using?
TIA
Create A Unique Random Integer

Generate Unique Code Help
Nov 6, 2007Hi Guys,
I am trying to insert a unique code, like a voucher code, into a table in MSSQL, 10 numbers (0-9) which obviously needs to be unique.
I can code this in ASP, but I think the process could be a bit long winded, i.e. create a key - run a stored procedure to see if it is free if not loop and check again. Surely there would be a way to do this in a stored procedure in one?
So the code would look like 3928492834.
1. Generate Key in SQL
2. Check if not used in column 'kcode' if it is, regenerate and check again.
Any advice would be greatly appreciated, I know how to do this in ASP but bit of a SQL newbie!
Thanks
