C# - Using LINQ To SQL To Search Entire Database?

Jul 7, 2010

Is it possible with LINQ to SQL to search the entire database (obviously only the parts that are mapped in the .dbml file) for a string match? I'm trying to write a function that will take a string of "Search Term" and search all mapped entities and return a List(Of Object) that can contain a mixture of entities i.e. if I have a table "Foo" and table "Bar" and search for "wibble", if there is a row in "Foo" and one in "Bar" that contain "wibble" i would like to return a List(Of Object) that contains a "Foo" object and a "Bar" object.

IDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?

Jan 17, 2011

I 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.

Could Not Retrieve Schema From Database

Jul 27, 2011

I am using microsoft access 2003 and visualbasic.net. I am trying desperately to add a database using the wizard, and it lets me go through with it, testing the connection is good, but when I try to finish it gives me an error: "<customers>Could not retrieve schema information for table or view customers." What am I doing wrong? I've added databases in the past without this problem using the same Access.

Retrieve All Parents From The Database?

Nov 17, 2011

I 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.

Forms :: How To Retrieve Values From The Database

Jun 7, 2012

i am new to vb.net and dont have any idea about using datareader.i am right now doing a project on vb.net and am facing an issue.i have a form, where in i have to select the matching records from the database and show it in various textfields. as far as the query execution is concerned, i have successfully completed it, but i am facing an issue now. Suppose, i have an Id of a student, and he has registered for 3 courses, when i give the query something like select students.studentid,courseid,midtermmarks,finalterm marks from marks,students where students.studentid=course.studentid;it gives me multiple records.my doubt is, when i get multiple records, and which is true(in the case a student has registered for multiple courses), how can i traverse through the resultset and fetch the values in the respective textfields.
