Auto-generate A Column Value?
Oct 1, 2014
I have a table called dbo.test. This table is built with two columns, namely; col_id and col_name.. Now, I want col_id to be auto-populated when a new col_name is added. But the col_id - should be of formulae xyyyy
where x = 2
and yyyy = will be incremental
Therefore, the first 3 records will be like ;
col_id Col_name
20001 A
20002 B
20003 C
......
......
and so on
Now, is there a way SQL can auto-populate teh col_id whenever a col_name is added?

Hello, I have a table (publication) that has a primary key pubID which is an identity specification. This ID already has relationships to other tables.
I am having problems trying to make one of the other columns in the same table to auto generate. This column (bibNumber) is not related to any other table. All i want to do is when i create a new record in the table, auto generate a number for this column bibNumber.
How can i do this?
I am using sql server express 2005
Regards

Is there an easy way to generate the parameters code for calling stored procedures?
Is there an easy way to generate stored procedure code without having to manually type it in? I've seen 3rd party tools, but I was wondering if there's anything within Sql Server to do it.
I'm using c#, visual studio 2005, sql server 2005.
Thanks,
John

Hi, in Access, I can use an Auto-Increment number for my primary key field. May I know how do I do that in SQL Express?
In addition, is there any tutorial on how to use SQL Express to generate customised unique numbers (such as membership number, Customer ID such as A001 where A is based on the customer's name while 001 is due to the fact that the customer is the first among those with names starting with A)?
Thanks a lot.

Dear everyone,
I would like to create auto-generated "string" ID for any new record inserted in SQL Server 2000.
I have found some SQL Server 2000 book. But it does not cover how to create procedure or trigger to generate auto ID in the string format.
Could anyone know how to do that?? Thanks!!
From,
Roy

Hey all,
1) I have a report with many parameters that I want users to be able to pick from. Allow them to pick 1, many or all to build their report dynamically. I'm all set on the TSQL side, but on the Reporting Services side I have to allow each parameter to be null with a default of NULL. In by doing this, the report will auto run, which I do not want to happen. The only resolution I've found thus far was by adding a parameter that does nothing, with a NULL default value. Yet It sticks out like a sore thumb on the report and I want to get rid of it. If I check in "Hidden" in the parameter options, my report errors out stating that the parameter requires a value.
2) Is it possible to have a parameter that has available values from a dataset have a NULL checkbox like those of parameters that do not have available values?
3) Is it possible to add back/forward buttons inside of a report instead of just at the report header by default?
Thanks!

Hello,
I have a column that is not auto-incremented. I would like to make it auto-incremented. For the moment, the only solution I found is to delete my column and to add a new auto-incremented column. The problem is I cannot delete it without deleting dependencies on it... So is there a solution to make an existing column auto-incremented or is it necessary to a create a new column ?
Thank you in advance for your help.

Here is my objective:
As part of auditing of our application, I want to write the values of all column in one row out to an audit table both before and after an update to see what the changes were.
I know I can SELECT * FROM tableName FOR XML AUTO to generate a single XML 'column', but I cannot figure out how to capture that output and store it.
According to MS, you cannot use FOR XML in a subselect, or fill a TEXT variable with the results of such (which, IMHO really diminishes the usefulness).
I want to stream out the results of one entire row and store that in ONE column of an audit table. XML seems like the easiest way if not for this limitation.
A better way?
Thanks.

Hi,
I have an auto incrementing int column setup which serves as my unique primary key. Just wondering what happens when the auto increment reaches the limit? Will it recycle numbers from the begining (who's rows have obviously been deleted by this stage)?

Hi,
I have the following two tables:
Code:
create table RECORD
(
ID int not null,
Issue_descr varchar(256) not null,
Priority varchar(5) not null,
Status varchar(12) not null,
Date_add varchar(10) not null,
Date_due varchar(10) not null,
Date_complete varchar(10),
PName varchar(32),
primary key(ID),
foreign key(PName) references PROJECT(PName)
);
and
Code:
create table STEPS
(
ID int not null,
Num int not null,
Descr varchar(256),
Date_due varchar(10) not null,
Date_complete varchar(10),
Status varchar(12),
primary key(ID, Num),
foreign key(ID) references RECORD(ID)
);
I have set PK "ID" in table RECORD to auto identity(1,1). I have done the same for PK "num" in table STEPS.
However I am seeking this behavior in STEPS:
ID num
-- ----
19 1
19 2
19 3
20 1
20 2
21 1
but what I'm getting is PK num doesn't "reseed" or reset to 1 as "ID" changes. PK num just auto-increments regardless of ID. Is there a workaround?
Thanks.

I'm a bit new to SQL Server, but here is the problem I am trying to getaround:1. I have lets say an Employee table where the emp_id is an identitycolumn that is auto assigned by the db.2. I wish to insert values into the tables, but sometimes I may wish touse the value of the emp_id that i supply while inserting (andsometimes not).Is there any way in MS SQL to do this? For e.g. is it setup like aconstraint that I can temporarily drop. I do not want to alter thetable, so that option is ruled out.Any other ways to do this (I know bcp is one of them that allows me todo this, but looking for ways in the db itself using SQL if possible)Thanks,Bharat

I am migrating a web application I wrote from ASP to ASP.Net, and fromAccess to MS SQL server.In the Access version, I did not use the auto number for creatinginvoices and other documents, because I heard somewhere (perhapsincorrectly) that if the db was ever compacted or otherwise changed,it could change the values of the auto-numbers. Not a good thing.So I wrote a routine that, just before creating a new record, wouldlook for the highest value in the table and create the new record withthe next number.So my question is, am I safe in assuming that in MS SQL that I can seta starting number for the next, let's say, invoice and that newnumbers will be issued in sequence, and that these numbers will neverchange? What happens if an invoice is deleted? is the number goneforever? Just wondering how others deal with these issues...thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake. It's Chinatown."

We are having xml data in a column. Is it possible to write a trigger to generate a mail if particular value get inserted in a tag.
For ex:
<File AF="910" PTO="ATN_P76035_PSQO" NNO="54545465" KTNNN="AX2" KL="" AD="99" PrqnT="AX2" Stab="21545" KE="45454" TE="65465" Rsaa="BBBB" AK="54544.AX2.POEAX2.546546546.NONTP.NONTP" AK2="">
In the above xml data if we have the value 21545 in Stab the trigger needs to be executed and mail needs to be sent to a distribution list.
The Trigger should not be initiated if value other than 21545 is updated...

I've data as below
account period01 period02 period03 period04
1111 null null null null
1112 782 null null null
1113 null null null 345
1114 765 882 67 321
What I want to achieve is to get values from period1 till period04 and used the lasted value to code the value of accoutperiod, if value is from period1 then code it as 01, period2 as 02, period03 as 03 and period04 as 04. So the output should be like this
account period01 period02 period03 period04 accoutPeriod
1111 null null null null null
1112 782 null null null 01
1113 null null null 345 04
1114 765 882 67 321 04

I have a RS Matrix element where I am attempting to genrate an expression that uses a value from a previous column. I have had no luck so far...
Here's a brief example of the matrix that I am using:
=Fields!MonthName (my one and only Column Group)
=Fields!ProductName =Sum(Fields!Count) =DifferenceExpressionInQuestion
I gotta use a Matrix since the number of months is dynamic.
In my test, I have 12 month columns. Under each Month column is a subordinate Count and a Difference column. In the Difference column, I want to calculate the difference in the Count columns relative to the previous month (if the Count for Jan is 15 and the Count for Feb is 27, then Feb's Difference column should be 12).
So, I am stuck trying to generate an expression for the Difference column. This expression needs to refer to the Count of the previous month.
RS's Previous() function cannot be used in a Matrix (because that's the compiler error that I get when I try to use it).
Does anybody know how to do this???
Do I have to use custom code to do this???
If I can't do this calculation in a matrix, then what good is it???
TIA!!!

Good day gentleman,
Is it possible to pad columns of Int data type with zeros?
I currently have a primary key column of data type Int which is auto-incremented by 1. My problem is I need to pad the auto-incremented ID's with ten zeros so, 0000000009 instead of 9.
I can pad the ID's in the c# dataaccess layer, but i need to generate/store them padded in the database to allow direct reporting.
I am using Enterprise Manager and i can see a Formula field when the table is in design view, can i use this? i am just guessing here.
Any comments or pointers would be a big help.
