I want to find data from a database which is close to the value of an inserted number by the user in text-box. When a user wants to insert number in text-box, if the number not matched whit the value of any data in the database it should not display empty, the database should display a close data for inserted number by a user in text-box.

What I have tried:

<pre> Private Sub BtnSearch_Click(sender As Object, e As EventArgs) Handles BtnSearch.Click
        If cmbtenstion.Text = "UltimateTensileStrength" Then
            Me.Table1BindingSource.Filter = "TensileStrength='" & txtTensile.Text & "'"
        ElseIf cmbDensity.Text = "Density" Then
            Me.Table1BindingSource.Filter = "Density='" & txtDensity.Text & "'"
        ElseIf cmbYield.Text = "YieldStrength" Then
            Me.Table1BindingSource.Filter = "YieldStrength='" & txtYeild.Text & "'"
        ElseIf cmbMoE.Text = "ModulusofElasticity" Then
            Me.Table1BindingSource.Filter = "ModulusofElasticity='" & txtMoE.Text & "'"
        ElseIf cmbCost.Text = "Cost" Then
            Me.Table1BindingSource.Filter = "Cost='" & txtCost.Text & "'"

        End If
    End Sub

Solution 1

There is nothing standard the provides for a "close match to a number" filter - you will have to sort the items by the absolute value of the difference between the desired number and the actual stored value.

Not simple, not at all.

Not an elegant solution, but you could do something like this:

SELECT TOP 1 * FROM Customers ORDER BY ABS( CustomerId - @myvalue ) ;
