Hi everybody,
I'm getting this error.
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Contract_ContractType". The conflict occurred in database "ContractDB", table "dbo.ContractType", column 'ContractTypeId'. The statement has been terminated.
I understand that this is because I'm not sending the exact ContracatTypeId to table. I'm doing this deliberately because I want to store Null as well for some reason.
Please could any body tell me how can I remove/drop this constraint from database (please bare in mind I have no table diagram).
any help will be much appreciated.

just goto your detail table where your Foreign Key exists , open the table and click on your field which is Foreign Key and right click and click on Relationships , select the specific relationship and on the right side Grid in table designer Set the value for 'Enforce Foregin Key Constraint' to 'No'

Just go to your table and Rename the table fields in Design View , if you want to do it script then you can click on Generate Change Script and it will Create Script for your

As the others said, plus you may want to use a third and temporary name to avoid a "Field name already used" error (like when swapping two variables).

Hello every body!
I am writing a C# application using SQL Server as a database. I run transactions on some tables of my database. I want to write something like a trigger for example, that if a transaction rollbacks, for whatever reason, the database itself tries it one more time and then send the response to the application. Is it possible or not? If yes, how can I do this?
Thanks in advance

Well any transaction is role backed by the database not by the Front end application because data within transaction does not full fill the criteria , Thats why is role backed.
It will not Commit the transaction unless and until it fulfills the criteria set whether you send this from front end or from back end

Hi,
I have a table of product movements between places,
Table Movements
{fromId, toId, date, productId, status, firmware, etc}
And a table of all the products
Table Products
{productId, name, status, firmware, etc}
My question is if its OK this design, in particular the bolded things.
In each movement some properties of the product will change (status and firmware), but the one that is really active and prevailing is the one in the Products table..
So if I want to know the prevailing status I'll ask the Products table.. and if i want to know the status that some product had last tuesday I'll ask the Movements table.
Another solution could be to have a table
Table ProductProperties
{productPropertiesId, status, firmware}
and the other two would be like:
Table Movements
{fromId, toId, date, productId, productPropertiesId}
Table Products
{productId, name, currentPropertiesId}
Any comments?

It's a little confusing...
At what point does the Product table get updated to reflect its new status/firmware etc? Why does moving something from one place to another change these? Can a product exist that never moves?
|
|
|
|
|
The last movement associated to some product determines its status/firmware.
But yes, there might be products that havent been moved ever yet.

This is definitely the best solution.
The other solution would only create one extra table you would need to query, making your queries needlessly complicated.

I probably wouldn't have status and firmware in the Product table. When a new Product created I'd create the first Movement (created, bought, whatever) record for that Product.
|
|
|
|
|
Oh thats a nice solution..
Though the movements are used in other parts of the software.. so this "dummy" movements would have to have different properties.. like "from = to"
|
|

|
|
You might instead have a dummy location for the from value, e.g. "thin air".

1. What type of database?
2. If using SQLServer, consider the following:
select count(*) from security_data
where charindex('Test',Resource_Desc) > 0
The table and column represent my data, but you should be able to modify it to your needs.

Hi tim
Thank your for your reply yes am using SQL2000

Hi Tim
select count(*) from CustomerDetails where charindex('@',EmailAddress) > 0
Here its showing total record count, i wish to get the count of emails with @gmail.com @yahoo.com, but i cannot hard code this cause the list is so big that it has to run a loop by itself
Kind regards
James

Using a different table on my end...
select distinct substring(email_distribution,charindex('@',email_distribution),len(email_distribution)), count(*)
from bow_reports
where charindex('@',email_distribution) > 0
group by substring(email_distribution,charindex('@',email_distribution),len(email_distribution))
Again, customize to your use.
email_distribution should be equivalent to your emailaddress
bow_reports should be equivalent to your customerdetails
