Forms :: How To Retrieve Values From The Database
Jun 7, 2012i 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.

Compare Values In Datagridview With Values In Database Before Inserting Into Database
Dec 15, 2010I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

Query Table Retrieve Filtered Values?
May 24, 2011I am trying to Query a table with data from another table and return a filtered result
Dim i As Integer = 0
For Each lrow In dtlist.Rows()
Dim lat As Double = dtlist.Rows(i)("Latitude") 'CDbl(Me.SubjLat_txt.Text)
Dim lon As Double = dtlist.Rows(i)("Longitude") 'CDbl(Me.SubjLon_txt.Text)
[code]....
Obviously doesnt work but the idea is thats the Value i need to put in the Value Column of dtlist In short the project, loops through one table(dtlist) of address's and gets the distances of it from the address's in the second table(dtsold) then gets the higest value from dtsold within a certain distance?

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.
