I need to generate random strings each of length 7 characters and update it in a table that contains employee data.For example. There is table called as Employee. It has Id, FirstName, LastName & Email as the columns. I need to mask the real names. So i have to generate random characters between a-z unique for individual records and update it in the table.

Input table

IDFirstNameLastNameEmail
1GlenJacksontest1@email.com
2ChristopherMcClaintest2@email.com
3Carol Kholertest4@email.com
4JamesDesototest5@email.com

Output table should be:

IDFirstNameLastNameEmail
1KhjkltgErstlkjtest1@email.com
2AsdlkfuAlsdkjftest2@email.com
3AlsdkflAldkjfltest4@email.com
4BasdfweAsldkfjtest5@email.com

I went through some websites for generating random characters. These provide a 7 or 8 character random letters. URL...But i do need to update 2 columns of an entire table with random characters.

Help!!!!to Generate Random Data....

Jul 8, 2007

Dear 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:

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 ?

How To Generate Random Default Value For A Field Under Sql Table?

Oct 13, 2005

hi
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

Returning Random Records And NOT Similar (random Questions)

Jul 20, 2005

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

Separate Lowercase Characters From Uppercase Characters

Mar 5, 2008


Hi everybody,
I would like to know if there is any property in sql2000 database to separate lowercase characters from uppercase characters. I mean not to take the values €˜child€™ and €˜Child€™ as to be the same. We are transferring our ingres database into sqlserver. In ingres we have these values but we consider them as different values. Can we have it in sqlserver too?

DTS Bug? (or Random Feature?)

Jul 16, 1999

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.

Random Numbers.

Jun 22, 2001

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()

Unique Random Row Id

May 4, 2006

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

Random From List

Jan 9, 2004

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
