Automatically Generating Values For PK
Aug 8, 2007
Hi,
I am new to SQl Server, i have created a logical model for a database that i am creating for a project. Is there a way i can assign automatic values to my Primary Key (PK) Column other than using an identity?
For example i have a table called indicator for which the Primary Key (PK) is indicator_identifier; i want the primary key values to be
ind_0001
ind_0002
ind_0003
Please note that i may be populating the tables from a VB.NET form
Please can anybody help me?

hi,
i am a newcomer and a freshman in asp.net. i am now writing a web-based system for SME as my final year project. i am going to use sql server and asp.net in C# to perform my final year project.
as asp.net is new for me, i would have some simple problems to ask.
1. in the project, i would like the system can automatically generate the enquiry number for each new order input to the system. for example today is 05 July 2006, the enquiry number would like 2006211xxxx, where 2006 is year, 211 is the day count start from 1 Jan and xxxx is the random number/ ordered number. how can i implement this? i even don't know how to generate the ordered number. could anyone help me
2. if there is an unknown test sample in each order input. as the sample number for each order is different, how can i set a flexible table that can have different number of rows for user to input the test result.
thanks
Rgds, universe

I've got some records like this:
ID_________Jan Feb...........................Dec
0000030257 0 0 0 0 0 0 1 1 1 1 1 0
where each month field has a 0 or 1, depending on if the person was enrolled that month.
I'm being asked to generate a table like this:
ID_________ Start_Date End_Date
0000030257 July 1, 2014 Nov 30, 2014
Is there some slam dunk way to do this without a bunch of If/Then statements?
The editor compressed all my space fields, so the column headers are off in some places.

BEGINNER QUESTIONI have a table which has a compound primary key consisting of two columns.One of these columns is a foreign key which is generated in another table byan identity.I want to be able to generate the other primary key column valueautomatically when an insert occurs but assume that I cannot use an identitybecause it would have to be unique for this table.There will be potentially more than one user accessing this table so I wantto avoid generating the key on the client side.How can I do this? Will it require some hardcore T-SQL?I hope this is clear (I suspect it isn't) I'd be happy to supply more info.I would be extremely grateful for any help!Mark.

I am building code to look into the database and create "CRUD" stored procedure scripts automatically for each table.
I am in the finishing stages as my procedures take into consideration all necessary parameters and keys wheter they are natural or identity. It also takes into consideration User Defined Types.
I am working on the section which defines the parameters and their default values. ie.
CREATE PROCEDURE [dbo].[TransactionHistoryInsertOne]
(
@ProductID Int = 0,
@ReferenceOrderID Int = 0,
@ReferenceOrderLineID Int = 0,
@TransactionDate DateTime = '1/1/1900', <-- Possibly arbitrary
@TransactionType nchar(1) = '?' <---- How to get this.
@Quantity Int = 0,
@ActualCost Money = 0,
@ModifiedDate DateTime = '1/1/1900'
)
AS...
I have three problems remaining.
1. Using the AdventureWorks database as a data model, I run into the TransactionType field in the TransactionHistory table, a non-nullable nchar(1). How do I determine and use any default values that may be defined for this object?
2. Do UDTs have default values already defined?
3. How do I make sure I am not arbitrarily setting the default values?
Here i my select statement into the system tables:
SELECT C.*, T.name as xtypename, U.name as xutypename, S.*, so.*
FROM syscolumns C
left join systypes T on (C.xtype = T.xtype) and (T.xtype = T.xusertype)
left join systypes U on C.xusertype = U.xusertype
left join sys.all_columns S on (C.id = S.object_id) and (C.name = S.name)
left join sysobjects so on S.default_object_id = so.id
WHERE (C.id = [TableId])";
Thanks for any help

I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.

I have created a report, and am setting default values for the parameters. Once the default parameters is set, the report automatically generates. Is there a way to make it not automatically generate the report? We are setting the parameters with values that will get the end user the most recent data, but alot of times, they will want to pull older data as well. We don't want them to have to wait for the report to automatically generate before they can change the parameter values

If all the parameters for a report have default values, the report runs automatically as soon as you open it. Is there a way to prevent this?

Is there a way that I can do this at the table level to automatically handle the rounding of seconds, etc. down to the minute automatically without having to use a trigger?
Here is a very basic example of what I am trying to do:
--example: '09-22-2007 15:07:18.850' this is the value inserted into the table by the code
select getdate()
--example: '2007-09-22 15:07:00.000' this is the value I want to store in the table
select dateadd(mi, datediff(mi, 0, getdate()), 0)

A common partitioning scenario is when the partition column has the same value for every record in the partition, as opposed to a range of values. Am I the only person who wonders why there isn't an option to automatically partition a table based on the unique values of the partition column? Instead of defining a partition function with constants, you ought to be able to just give it the column and be done. This would be particularly valuable for tables partitioned on a weekly or monthly date; when new data is added it could simply create a new partition if one doesn't already exist.

hi,
I am developing a ASP.NET application using SQL Server as my database.
I want to create a number that is unique.
The number will have 8 digits.
first 2 digits correspond to year. ex:04 or 03
the next 6 digits start with 000001 and it should get added for each new entry of data.
i am not able to generate number in the way i said. I am relatively new to SQL. so any suggestions as how to go about solving the problem???. Are there any samples/codes available for this.
Any help would be highly appreciated.
thanks,

Hi all,
I have generated an SQL script such that when it is run, it will automatically create tables if not existing or drop the existing tables. The problem I have is that, is there any way I can also make the script create not only the tables but also transfer the data from the old database to the new database?
I would really appreciate if any of you could point me to any existing programs, scripts etc that can do that. Thanks in advance
Regards,
Celia

Is there a way to generate SQL Scripts from a stored procedure?
For disaster recovery and documenation reasons, we'd like to create scripts of our databases periodically. I, being somewhat lazy, would like to automate this so I really don't have to remember to run this every so often.
Any help would be appreciated.

THEN SUBSTRING(ISNULL(max(seed),'00000'),7,12)
ELSE '000000'
END AS SEED

Hi,
we would like to generate SSIS packages(connections, data flow tasks, etc..) programatically using C#. Is it possible to do so?
At present we are creating packages by dragging and dropping required componets from toolbox and configuring them manually. We have a requirement of creating around 300 packages every week. Manual creation of packages is really a nightmare.
I heard from one of friends that using c# we can create packages. is it true? if so, can we view/edit the packages generated using c# using VS 2005 IDE(if required) ?

I'm having problems generating the primary key for a sql server table. I use a slowly changing dimension to discriminate modified and new records. The primary key in the SQL Server table is a combo number/letter incremental (ex. 0000A, 0001A...9999A, 0000B...). I tried creating Instead of insert and For insert trigger for a table but this doesn't seem to do the work.
What are my other options? How can I generate a primary key for every new row?
Any advice is appreciated.

Hello all,
I have a few questions relating to scripts and I'm looking for some help, or at least a point in the right direction.
1) I'm generating CREATE scripts to move a number of tables/procedures/functions from my testing database to my production database. The issue I have is the script doesn't seem to be generated in a particular order, so I'm getting errors when a table/procedure/function is created that references something that hasn't been created yet. Is there a setting available to create the script in a specific order to prevent these errors?
2) This is somewhat related to the first question. I need to drop all the tables/procedures/functions before I re-create them. Can I set all the DROPs at the beginning of the script, and then run all the CREATEs?
3) Eventually the database will be ready for production and in use. And eventually I'll be asked to make changes, without erasing existing data. Can I accomplish this using the generate scripts feature? What topics should I be investigating when looking into conducting these types of updates? "Updating database" is too general and I'm not sure the technical term. I've done very simple DB-related tasks so I'm trying to figure out what I'm looking for so I can educate myself. Basically, I don't know what I don't know.
Any help is appreciated. Thanks.

Hi all,
I have a question about generating membership numbers on the fly when someone registers to my website.
Rather than using the auto increment field as a membership number, I would rather keep it as just as the ID for the record and I would like to have a seperate membership number that looks something similar to this...
SR357324J
This will then stay with them for the lifetime of their membership and be on their printed loyalty card.
My questions are...
1) Is there a 'good practice' for membership number format and generation?
2) If this was used as a unique field, is there a degradation in performance when looking up records due to it being alphanumeric.
I may be well off base here, however these are my thoughts so far and your opinion/help is greatly appreciated.
Thanks for your contribution.

Hi, I'm looking for a way to take an XML feed and basically do what this article describes: http://msdn.microsoft.com/msdnmag/issues/03/05/MetaDataServices/
(In short, take in XML, generate a database generation script, creating that database, then load the XML data into said database.)
But, the above article involves user interaction and I would like this all automated, ie: in .NET 2.0/C#
Does anyone know how to do this?
Cheers,
