Question

I am new to .Net and I am working on one task. Below is my scenario.

I have 2 tables:

• Table 1: Students

  StudentID   StudentDetail
      1         StudentName
      2        StudentGrade
  

• Table 2: Student_data

  StudentDetail  StudentRecords
   StudentName   John (Default)
   StudentName      Jacob
   StudentName      Smith
   StudentGrade            A    (default)
   StudentGrade            B
   StudentGrade            C
  

Question: When window form loads (run time) I need to display StudentRecords in combo box with StudentName = "John" and StudentGrade = "A" as default followed by other values.

StudentName and StudentRecords are in Labels and values are in a ComboBox.

I am using VB.Net and VS 2010 with SQL 2008r2.

I would appreciate any step by step help. Apologies If my request is simple.

Answer 1

I think you should think to start rethinking your data model. Some like this will be enough:

This way you can have:

• Student

  id       name       [   oGrade    ]
  

  ---

   1       John       [      1      ]
   2       Paco       [      1      ]
   3       Jacinto    [      2      ]
  

• Grade

  id       grade      [   aoStudent    ]
  

  ---

   1         A        [   John, Paco   ]
   2         B        [   Jacinto      ]
   3         C        [   Nothing      ]
  

Anyway, this way you only can have a Grade per Student. So, it’s not much helpful. Something more complex is needed if you want to keep a track of the students grades for each subject and several tests per subject. Here you have another model a little more complex having that into account:

Again, you need to stop and think about your problem.
