Hi Experts,

I have a situation where I need to check where the two different entities M & S have the same range. If they have the same range then I need to draw a diagram on the both M & S. If they do not match up then i need to just draw a diagram on M. How to check and search through the data in sql server?  Thanks

So two different rows in the database? Or are you trying to compare two tables?

Here is an example
Note that I used dummy names such as EntityName, EntityValue which you will need to replace with your actual column names.

Dim dbadp As New System.Data.SqlClient.SqlDataAdapter("Select * From tablename Where EntityName In ('M', 'S')", "Your connectionstring here")
Dim dTable As New System.Data.DataTable
dbadp.Fill(dTable)
dbadp.Dispose

if dTable.Rows.Count = 2 Then
   If dTable.Rows(0).Item("EntityValue") = dTable.Rows(1).Item("EntityValue") Then
      'Same value
   Else
      'Different value
   End If
End If
