Question

ADO.NET DataTable Select Row if Found Get ID

Asked by: sainavya1215

hi,

TBL_Values

ID        value1      value2           value3
==========================
1          10             29                 1
2          30             32                 3
3          34             45                 5

When User passes a value like for eg :   24  (program should check in what range it lies ie value1= value2  and output the corresponding value of value3

considering 24  it lies inbetween 10-29 (value1-value2) so it should show value3 value which is 1

for this I had written code which returns a dataTable. But I am not able to figure out how we can return the value3 value  using DataTable.select
statement

Here is the code

Dim cnn As New SqlClient.SqlConnection

          dim x as integer = 24  'hardcoded to test
        Dim dt As New DataTable

        Dim strsql As String

        cnn.ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;database=test;server=LOGO"
        cnn.Open()
     
        Dim SQLAdapter As SqlClient.SqlDataAdapter = New SqlClient.SqlDataAdapter("select * from tbl_values", cnn)
        SQLAdapter.Fill(dt)

        Dim dr As DataRow()
           
           dr = dt.select("value1<=x  and x<=value2)  
 

       IF FOUND WE need to get the corresponding value in value3 column / If not found just display message.
