Try the one I painted.

Yeah, easiest way to not have the problem is to not edit, but to add.

would you correctly resolve updating the status two completely different ways?

Yes.

But then again, we already noted that adding a record, as opposed to editing one, would solve that.

You have a customer with two different employees. Both of them call the service desk at 8:50am on Tuesday June 6th. Both want to do wildly different things to the same thing.

This means the customer has tasked them both with the same task. And that both reached wildly different outcomes with regard to what should happen.

No that doesn't seem like a scenario which is likely to occur and in fact is wildly unlikely to occur. Thus prioritizing this even to the extent of writing the requirement much less implementing it seems very unlikely.

But again that is not the point. There are valid, probable and needful reasons for adding a record versus update that have nothing to do with the highly likely scenario that you have posited.

Personally I don't consider that an audit solution, I say solution because audit is a whole lot of objects.

However that should depend on business needs. If you need to track every change in the system then something like your solution is required.

But there can be a much lower need so less of a solution might be sufficient.

Always, this is the mantra I repeat at the start of every requirements meeting, I want it tattoo'd on the foreheads of every BA, I want "it is your job to interpret their requirements CORRECTLY" tattoo'd on their buts!

I'm old I've been doing this for a bloody long time, the number of times I have had this ~~argument~~ discussion with BAs and user are innumerable. I just hate it when I have to pound it into the head of a senior dev.

Mind you I'm delighted when they (the BAs and senior devs) come up with some novel concepts especially when they work.

That's a great statement. What was the result? Did you get any error messages? What does the log file of the installer tell you?

The installer every time was telling me that the installation failed and I did not know the reason however finally I got the solution the .exe package I was trying to install seems to be not complete as I download another one from microsoft site and when I tried again it worked fine.

Your excel sheet is probably formatted with comma.

You should split out your unpivot and inspect the results of the query to try and determine the invalid data, look for blanks, character and formatting (commans)

Can not connect to my database from asp .net application

Re: Can not connect to my database from asp .net application

5-Jul-14 0:15

I have a named instance of 2008 r2 located on my windows 7 professional local machine. I have tried to get my connect string to work but I just cant. I am using machine name "HOLDORF-PC" SQL instance name "SQL_2008_R2" and the rest of the connection string. Here is my connection string:

"Data Source=HOLDORF-PC\\SQL_2008_R2;Initial Catalog=EFDataModel" providerName="System.Data.SqlClient" />

Please help

Sorry, I tried this:

"Data Source=HOLDORF-PC\\SQL_2008_R2;Initial Catalog=EFDataModel; Integrated Security=True"

and it still doesn't work. One point is that this is the connection string that coexists with my Entity Framework model.

Re: Can not connect to my database from asp .net application

OK. I think you were right on the DB connection string. Now, I'm getting this error:

An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.

Here is my Entity Framework connection string:

<add name="EFDataModelEntities2" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=HOLDORF-PC\SQL_2008_R2;initial catalog=EFDataModel;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />

And here is my Model connections:

<EntityContainer Name="EFDataModelEntities2" annotation:LazyLoadingEnabled="true">

<EntityContainerMapping StorageEntityContainer="EFDataModelModelStoreContainer" CdmEntityContainer="EFDataModelEntities2">

I don't use EF; I've no idea what it epects beyond a normal SQL-server connection string. According to MSDN[^] your string looks correct.

Where does your asp.net application run - on the same machine? If not, configure the SQL Server to accept connections from other machines.
And what about the account the IIS is running with? Does that account have sufficient access rights to the database? I suggest SQL Server authentication instead of WIndows authentication - do not forget to configure your SQL Server to allow that.

Is the double back-slash between the machine name and the instance name a typo in your question, or a mistake in copying the connection string from a C# source file to the web.config file?
