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

Hi, I have the lovely task of overhauling some of our SQL-based systems. I've found many tables that don't have unique identifying numbers that really should have them. I've searched around and people keep mentioning the Identity field as being similar to Autonumber in Access. The only examples I could find involved setting up a new table... but I need to add (and populate) an identity column to an existing database table. Does anyone know the command for this?
Example... my table is called PACountyTown. It currently has 3 columns: County, Town, and Area. I wish to call the identity-ish field RecordID.
Thanks in advance!

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:

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 ?

If you run this script you always get result between 1 and 4
SELECT dbo.Func_Rand(4, NEWID())
BUT, in this script sometimes have no result !!!!!!! why??
SELECT 'aa'
WHERE dbo.Func_Rand(4, NEWID()) IN ( 1, 2, 3, 4 )

I am doing a shopping basket type demo.I have difficulties going from table with fields like (Name,ProductCode) to table(Name, ProductCode, NumberOfItems). One way could be adding just Name and ProductCode fields and let NumberOfItems come automatically. It could have some common value like 1. How should I do this with VB.

I have a datatable : Data_Table and a look up table: Lk_table. Myfield that I
use in Inner Join is defined in both the
data and look table.
So I build my query like this:
SELECT * FROM dbo. Data_Table INNER JOIN
dbo. Lk_table ON dbo.Data_Table.MyField = dbo.Lk_table.Myfield
The pb, sometimes I
have myfield still with its default null value in the datatable: Data_Table.
So, I end up getting 0 record when I execute the query shown above.
How do I turn that around so that even if myfield in Data_Table
is Null, I still get the records from Data_Table. (I don t want a set of
records including all possible values from the look up table: Lk_Table)

Hi All,
I need to create a new field on a table and have that field default to another field value in that same table. Is there a way to do this w/ a default constraint rather than adding a trigger to the table? If i can't use a default constraint does anyone have a template trigger i could use? Below is an example of what i'm trying to do (Field_C is the new field and i want it to use Field_A value if no other value is specified on insert). Any help would be greatly appreciated.
alter table FOO add Field_C varchar(50) not null constraint FOO_default DEFAULT Field_A
thanks,
Dave

I am building a simple table, populated by ASP form, where every record should be assigned a unique ID. When working with Access I used `autonumber` datatype to keep track of every record. Can something like this be done with MS SQL server, if not what do you think is a good way to solve the problem ??
Thanks,

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

I'm copying MyDbTable to TempdbTable. There are 12 fields and I'm ignoring 11 of them when copying the one table to another with DTSWizard.
Once the TempdbTable is there, I'm adding 2 fields along with the one that is there already.
1) field1 int, Nullable, Default value ((3))
2) field2 tinyint, Nullable, Default value ((1))
The reason why I'm creating these two fields and giving them a value so they will match up when I import TempdbTable to MyDb2ndTable.
The problem I'm having is... field1 and field2 have a Null value intead of the value I'm giving them.
I'm new at this, so maybe the cause of the problem is obvious, but if anyone can help me I'd really appreciate it.
Thanks,
Bill

In SQL Server 2000 / Asp.Net I am trying to use default values for all fields; hoping to eliminate nulls.
For number and character fields, the default is pretty obvious, but is there any empty value for a date field? I think a null there might be better than putting in a bogus date, at least it can be tested for.
Are there any more developend ideas on this question?
Many thanks

I am creating a new filed in SQL Server 2005, and I want the field to have the default of '0'
I select the data type as numeric and save my changes, I then visit our front end database to see if the default value is just '0' but it appears as '0.00'
SO i thought about changing the default value to int (im thinking this means integer?) and changing it to '3' but it still displays the decimal point and two 0's
Am I doing something wrong here? I just want it to display '0'
Thanks

Hello.
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.
