IDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?
Jan 17, 2011I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.

View 4 RepliesRetrieve All Parents From The Database?
Nov 17, 2011I am using MVC3 and EF 4.1 (Oracle DB). Let's suppose I have:
Public Class Parent
Public Property Id As Integer
Public Property Name As String
[code]....
I want to retrieve all parents from the database and for each parent I can access its children.I want to do the following:
Dim firstParent = (From q In db.Parents Select q).First()
For Each child In firstParent.Children
'Do something
Next
The problem is that I would like to enumerate the children from the youngest to the oldest. Is it possible without the client-side sorting? If yes then how can I achieve that? I know how I could achieve what I want with an SQL query, but I cannot make it work with LINQ...
EDIT:Since this seems not to have a solution in my case and sorting everytime I request data is not an option, maybe there is something I can do when I insert the data to the database? I do not have a control on which order EF saves items to the database when I call db.Save(), but maybe there is some syntax I could use to require ordering based on some property.
