Search Tables in a Dataset OLEDB Data Source

The DataSet contains DataTableCollection and their DataRelationCollection. The DataTableCollection contains zero or more DataTable objects. The data inside Table is in the form of Rows and Columns . The OleDbDataAdapter object allows us to populate DataTables in a DataSet.

In some situations we have to find how many tables inside the Dataset Object contains . The following VB.NET source code shows how to find the tables inside the Dataset.




Imports System.Data.OleDb
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim connection As OleDbConnection
        Dim oledbAdapter As OleDbDataAdapter
        Dim ds As New DataSet
        Dim sql As String
        Dim i As Integer

        connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
        sql = "Your SQL Statement Here"

        connection = New OleDbConnection(connetionString)
        Try
            connection.Open()
            oledbAdapter = New OleDbDataAdapter(sql, connection)
            oledbAdapter.Fill(ds, "OLEDB Temp Table")
            oledbAdapter.Dispose()
            connection.Close()

            For i = 0 To ds.Tables.Count - 1
                MsgBox(ds.Tables(i).TableName)
            Next

        Catch ex As Exception
            MsgBox("Can not open connection ! ")
        End Try
    End Sub
End Class

connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
sql = "Your SQL Statement Here"

You have to replace the string with your real time variables.
