Using SQL Compact Edition?
Dec 3, 2011
Im looking for some advice on the deployment of an application using SQL Compact Edition.My application will only be used by two people on two separate desktops with file sharing enabled.My goal is to deploy the application and have the .sdf file located on one of the desktops in a shared folder. So the other person using the app can connect to that database too.What is the best way to setup the deployment of this so that I can place the DB in lets say c:DBMyDB.sdf

I am trying to do multiple joins within a single query in SQL Server CE. I know that SQL Server CE doesn't support multiple SELECTs but I can't find any information on multiple INNER JOINs. I keep getting token errors on ProjectItemMaster (after the FROM) and the first INNER JOIN. Warning this is a big ugly query used to generate reports.
[Code]...
If I can't uses multiple INNER JOINs I can I break the query down into a number of different queries but I would prefer not to. So it is easier to maintain a SQL Server CE and an SQL Server version of the program.

I have an application that is currently using DAO and would like to move it to ADO.Net. The problem I'm having is that when I do, I cannot do any queries that take variables if the database is Access or SQL Server Compact Edition. For example: SELECT RecipeName FROM tblMasterRecipe WHERE CategoryID = iCategoryID..The database is a local standalone database. Of course if I use the Standard SQL Server I can add parameters just fine using the TableAdapter Query Configuration Wizard. How do I do something similar for Access or SQL Server Compact Edition? The Create new stored procedure radio button is greayed out when the database is Access or SQL Server Compact Edition.

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

I am trying to compact a Access 97 MDB file. I have found and tried the following code
Private Sub CompactDB()
Dim jro As JRO.JetEngine
jro = New JRO.JetEngine()
jro.CompactDatabase("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>", _
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>;")
MsgBox("Finished Compacting Database!")
End Sub
This codes works and seems to compact the file and it appears in the destination folder but when i try to open the new file i get an error "Unrecognized database format 'DATAPATH'"Is there something i am doing incorrect? the database file sizes range from 5Mb to 100Mb+

In Visual Basic 2008 Express with SQL Server Compact 3.5 and the Usual DataSet / TableAdapters, My Query is too long:Changing the names, it is a query like this:
SELECT Table1.*, Table3.*
FROM Table1
INNER JOIN Table2
ON Table1.ID = Table2.T1ID
[code].....
Problem is, Table1 and Table3 have around 10 and 5 columns each, with rather descriptive names, and The Table adapter is insistent on writing all the columns out and therefore hacks off my command. (It won't take * 's, it always says it can't find the column Table1.* )
Is there a way around this?

I have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.
