Well, I have tried the following code:

Private Sub Query3_PreprocessQuery(ByRef query As System.Linq.IQueryable(Of LightSwitchApplication.Stock))
query = From n In query _
Group n By n.Order_Date.year, n.Order_Date.month, n.Product_Name Into g=Group _
Select year,month,Product_Name,Quantity = g.sum(Function(n) n.Quantity)
End Sub

My code causes the screen based on Query3 not to load any data...

Please help me, I need to get each product quantites (grouped per month and per product name).

Thanks is advance

ok, I have also SQL 2012 installed with server already created named SQLserver12
would you please tell me how should be the right connection string?

OK, now I downloaded SQL Server 2014 and I followed the next steps:

1- I made a SQL Server Instance named: MYSQLserver

2- I Created a database called: MyDatabase attached to MYSQLserver

3- and already I attached a new LightSwitch project to that database as an external data source, and the connection string was:

"Data Source=EHABELNAHAS-PC\MYSQLserver;Initial Catalog=MyDatabase;Integrated Security=True"

4- Everything is ok, now I'm trying to publish the application, now what is the "How do you want to publish the default database?" for?? and what should I choose from the two options?

5- Second this is Visual Studio 2013 LightSwitch Publish wizard now asks me for three connection strings:
•Is the Attached Data Sources connection string
•Is the User connection string
•Is the Publish database Schema

I put the same connection string in all connection strings "PC\MYSQLserver;Initial Catalog=MyDatabase;Integrated Security=True" but it always give the error "An exception occurred when deploying the database for the application. Couldn't deploy package"

and when double click on it, it takes me to:

<

Target Name="DeploySchema"

Condition=" '$(ExecuteSchemaDeploy)' == 'true' ">

<

DeploySchema ConnectionString="$(PublishConnectionString)"

IncludeSecurityDBObjects="true"

ServerArtifactsFolder="$(_ServerArtifactsFolder)"

Collation="$(DatabaseCollation)"

IntrinsicDacPackageFilePath="$(_IntrinsicDacPackageFilePath)"

DatabaseProject="@(_DatabaseProjectItem)"

Inputs="@(ServerMetadataFiles)"

ProjectPath="$(MSBuildProjectFullPath)"/>

Please Help

EHABELNAHAS-PC\SQLEXPRESS always gives an error no connection established to EHABELNAHAS-PC\SQLEXPRESS

ehabelnahas 31-Aug-14 15:54pm View

I'm afraid I couldn't achieve that...
I have now SQL server 2012 installed and I tried many instances of connection strings without success!!
I couldn't publish the application at all using connection string referring to a pc on my network.

Data Source=EHABELNAHAS-PC\SQLEXPRESS;Initial Catalog=Application2aPP;Integrated Security=True;Pooling=True;Connect Timeout=30;User Instance=False

I need 1st to be able to publish the application :(

Many thanks, I will try that and feed you back,

well, If that works, do you mean that I have to install SQL server in the pc having the database only? or it will be also necessary that SQL being installed in all pcs?
