Rpt-files do not function anymore after deploying to a different database

Question

first: I use CR. 10.2.3600.0 and Asp.NET with Visual Studio 2005
I developed my reports against a Develepment-Database and everything worked fine.
Then, I published my Website with the reports.
Also I made a backup of my Develepment-Database to become the Productive-Database.
All pages of my website function well (database-queries etc.), but when I try to call one of my reports a queerish error message occurs:
"This field name is not known. Error in File C:\WINDOWS\TEMP\...\{...}.rpt: Error in formula. '{xyz.ds_id} = {?@ds_id} and '."
I mean, the database is the "same" as before?!?
(BTW: the logon to the database is set at runtime and is ok.)
Why do the reports not function anymore?
The only workaround I found is to open the report in Visual Studio 2005 again and select  "Crystal Reports/Databases/Check Database" against the Productive-Database.
After that the report works! BUT THIS COULD NOT BE THE SOLUTION, this means that I cannot publish my website to a different database on a customers network!!!

Answer 1

I tried this:
Private Sub SetDBLogonForReport(ByVal myConnectionInfo As ConnectionInfo, ByVal myReportDocument As ReportDocument)
        Dim myTables As Tables = myReportDocument.Database.Tables
        ' Get Location of Database from web.config
        Dim Location As String = String.Empty
        Try
            For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In myTables
                Dim myTableLogonInfo As TableLogOnInfo = myTable.LogOnInfo
                myTableLogonInfo.ConnectionInfo = myConnectionInfo
                myTable.Location = myConnectionInfo.DatabaseName & ".dbo." & myTable.Location.Substring(myTable.Location.LastIndexOf(".") + 1)
                myTable.ApplyLogOnInfo(myTableLogonInfo)
            Next
        Catch ex As Exception
            Me.LabelError.Text = "(SetDBLogonForReport) " + ex.Message
        End Try
    End Sub
and get the error:
ex.Message     "Fehler beim Laden der Datenbankinformationen.
Details: Die Datenbank-DLL 'crdb_query.dll' konnte nicht geladen werden.
Fehler in der Datei C:\DOKUME~1\MSCHAE~1\LOKALE~1\Temp\RzpReport {748C95B6-70EC-45B9-953D-64DA215BD9DC}.rpt:
Fehler beim Laden der Datenbankinformationen"
which means in english:
ex.Message     "Error while loading database information.
Details: the databse-dll 'crdb_query.dll' could not be loaded.
Error in file C:\DOKUME~1\MSCHAE~1\LOKALE~1\Temp\RzpReport {748C95B6-70EC-45B9-953D-64DA215BD9DC}.rpt:
Error while loading database information"
I debugged the code and recognized that the error appears while setting the .Location property...?!?
My DatabaseName is "Rezepturverwaltung".
Example 1 with a command:
Befor setting the Location of mytable the value of the prpperty is e.g. "command".
After setting the value like in code above the value changes to "Rezepturverwaltung.dbo.command"
Example 2 with a stored procedure:
Befor setting the Location of mytable the value of the prpperty is e.g. "sp_GetData".
After setting the value like in code above the value changes to "Rezepturverwaltung.dbo.sp_GetData"
What`s going wrong furthermore???
