I am somewhat of a novice, so please forgive me if the phrasing of this question isn't clear.
I am working with an SSEE 2005 db and have imported the first of many tables into my Visual C# 2008 EE data sources. I have based a control on this datasource and everything works great.
The table in the db has, along with a primary key, a unique index. I went into the IDE and updated the proper field's Unique property to True and once again it works great. I get a message when I try to duplicate a value in that field.
My question, though, is how do I change the message? Basically I'm looking the for the event code that fires when a DataSet validation rule is broken. Are they all the same (meaning the same event no matter what the error) or is there a unique error event that happens when a Unique constraint is broken? Also, is it handled by the individual tables or from the master dataset?
Any help would be much appreciated.

You mean something like "violation of index idx_unq_foo cannot insert duplicate key" you want to change that? Its a global you can find by running SELECT * FROM master.dbo.sysmessages WHERE description like '%error%'
The best method to make a customized message is the use a try catch in c# and catch SQLException. customize the message based on the exception type.

I am creating a new record in the database.
The key is an identity field and the database is set to not allow inserts of assigned values.
I need to return the results of the INSERT to the user.
Is there anything I can do in my SQL that will let me return that key value? Is there something like a @PrimaryKey?
Thanks

Hi,
I need to work with SSRS & SSIS. Thinking that this will be available along with Visual Studio .Net 2008, I have installed the same. But to my surprise, I couldn't find SSRS or SSIS under Reporting Services other than Crystal Reports. How can I install the same? Is it available along with VS 2008 or coming seperately? Please provide any help.
Thanks in advance

This is not the right forum to ask this question. Post it in ASP.Net forum
In Asp.Net, just declare a integer variable and then increment it with 1 , like
int i = 0; i++.
In sql server, you can use the Identity columns for increasing automatically. By default it will increment by 1.

hello all,
I'm getting this error when connecting to my sql server 2005 with asp.net 2.0
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)

if your database service running and you can use it on local machine that could be wrong connection string(user/pass/server) or sql ports being blocked by firewall on server.

If you are using SQL Server (you haven't said) then
if not exists (select 1 from sysobjects where xtype = 'U' and name = 'table2')
begin
create table table2.......
end
will do it. There are several other ways too.

Another way to do it is (just replace your object names in the carrots):
If Object_Id('<database>.<schema>.<table>') Is Not Null
Begin
Create Table...
End
Which is pretty much the same as posted above, it's just using a system function. It can also work with temp tables:
--Assuming that #table is the temp table name.
If Object_Id('tempdb..#table') Is Not Null
...

Hi,
I have a c# (.Net 2) program that connects to access mdb file.
I use strong typed dataset to do this.
Now I have searched the web and found ms sql connection string
I replaced what was generated by the wizard with the new one and
now I can successfully connect to MS SQL server (with the same table).
The problem starts when I try to delete rows from the table.
In access it works great obviously, But with MS SQL I get exception when calling udpate (Wrong syntax near '.').
Is it possible at all to use strong typed datasets to connect to both MS SQL and ACESS. If yes how?
Thanks,
Yaniv

The SQL syntax is different between Access  and SQL server. You are not going to be able to just change connection strings - you will need to duplicate some/all your SQL statements to conform with the TSQL syntax.

Hi,
Thanks for your reply.
I ran the sql query: DELETE FROM table1 WHERE id = 1
on both access and ms sql and it worked fine.
But I don't create the queries manually, It is created by the adapter (I think) of my strong typed database ( so I don't know whats really going there).
Is there a way I can view the query created by it?
Sincerely yours
Y.R.

This where you have a problem. You are using the MS built in tools and therefore have only limited knowledge and understanding of the mechanics of the database and the DAL.
I suggest you completely reengineer your application to use a proper data access layer where you have control and understanding of the DAL and database operations.

I have absolutely no idea (but would expect it to be there somewhere) as I have only used the built in stuff enough to identify what a disaster it can be.
BTW this is not a rant against you, everyone has to start somewhere and you have asked intelligent questions and shown a willingness to learn. Do some reasearch into DALs, there are plenty of examples around.

Before we started the project we checked and found strong typed datasets the most fitting solution, Though some people strongly advised against it.
I works fine in a different area of my project (With mysql), So I don't know why people dislike it so much, But I have little experience with databases so I guess you have your reasons.
Anyway, For my specific problem I will do as you suggested and further my research in to the DALs.
Thank you very much you really helped me.
Sincerely yours
Y.R.

can u explain the meaning of multivalued dependency and functional dependency with an example .
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Functional dependency example: a Human Readable Code (like the hex value CFADE) created based on an Internal ID (850654) of a record (the Internal ID precisely determmine the hex value )
(One)Internal ID -> (One)Human Readable Code
Multivalued dependency example:
(One)Internal ID -> (One)Human Readable Code -> (Multiple)Account Number
You can find some examples here:

Hi all,
How do I connect to a MS-access data base which is present in localhost from an application runnig on web server. I want to send data from DB Server (sqlserver 2000) which is on remote machine to Ms-Access DB present in localhost.
After googling I found the following
Open connection to Access database located on a remote server:
"Provider=MS Remote; Remote Server=http://Your-Remote-Server-IP; Remote Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\App1\Your_Database_Name.mdb"
But, here my localhost IP varies depending on the client's system on which the web application is running. So, how do I set the clients' IP value or is there any other way to acheive this.
Thank U all,
Kiran
