Hi is it possible to fill a list box from two SQL tables

firstname lastname

thanks

M

Thanks for the reply I have tried using

SELECT tenant.firstName, tenant.lastName FROM tenant JOIN Name ON tenant.firstName = firstName.lastName",

I get an error invalid object name Name I thought Name was a temp table?

I should have said fill a list box from two columns in a table

SELECT column_name(s) FROM table_name1
UNION ALL
SELECT column_name(s) FROM table_name2

Edited 5 Years Ago by aldeene: n/a

Ur not using the join in proper way. Do u have Any relation between the two tables?
Primary key and foreign key constraints?

SELECT tenant.firstName, tenant.lastName FROM tenant JOIN Name ON tenant.firstName = firstName.lastName",

You could create a view by joining both tables and then fill up your listbox from the saved VIEW

I used this to achieve what I wanted

Public Class Tenant
        Private _t_id As String
        Private _firstName As String
        Private _lastName As String
        Private _existing As Boolean

        Public Property ID() As String
            Get
                Return _t_id
            End Get
            Set(ByVal value As String)
                _t_id = value
            End Set
        End Property

        Public Property FirstName() As String
            Get
                Return _firstName
            End Get
            Set(ByVal value As String)
                _firstName = value
            End Set
        End Property


        Public Property LastName() As String
            Get
                Return _lastName
            End Get
            Set(ByVal value As String)
                _lastName = value
            End Set
        End Property

        Public ReadOnly Property Name() As String
            Get
                Return LastName & ", " & FirstName
            End Get
        End Property

        Public Property Existing() As Boolean
            Get
                Return _existing
            End Get
            Set(ByVal value As Boolean)
                _existing = value
            End Set
        End Property

    End Class
    Private tenants As New List(Of Tenant)
    Private Sub editTennant_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles editTennant.Click
        RadPanelEdit.Show()
        RadPanelAddTennant.Hide()

        Dim connString As String = My.Settings.strConn
        Dim conn As New SqlConnection(connString)
        Dim reader As IDataReader
        Dim cmd As New SqlCommand
        cmd.CommandText = "SELECT t_id, firstName, lastName, existing FROM tenant"
        cmd.Connection = conn

        Try
            conn.Open()
            reader = cmd.ExecuteReader()

            Do While reader.Read()
                Dim person As New Tenant()
                With person
                    .ID = reader(0)
                    .FirstName = reader(1)
                    .LastName = reader(2)
                    .Existing = reader(3)
                End With
                tenants.Add(person)
            Loop

        Catch ex As Exception
            MsgBox(ex.Message)
        Finally
            conn.Close()
            conn.Dispose()
            cmd.Dispose()
        End Try

    End Sub

 

    Private Sub lstAdvocates_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadListControl1.SelectedIndexChanged
        If RadListControl1.SelectedIndex > -1 Then
            Dim tenants As Tenant = RadListControl1.SelectedItem

            RadTextBox5.Text = tenants.ID
            RadTextBox6.Text = tenants.FirstName
            RadTextBox7.Text = tenants.Existing
            RadTextBox8.Text = tenants.LastName

        End If
    End Sub

    Private Sub RadButtonUpdateT_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub

    Private Sub RadButton1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click
        Dim tempList As New BindingList(Of Tenant)(tenants)
        Dim bsource As New BindingSource
        bsource.DataSource = tempList
        RadListControl1.DataSource = bsource.DataSource
        RadListControl1.DisplayMember = "Name"
        RadListControl1.ValueMember = "ID"
    End Sub
