if Table1 and Table 2 have the same structure, can you use a 'union' ?

tbl 1 and tbl 2 have diff structure and data.I wants to fetch data and put into dataset as set of tables

Try two Fill commands:

C#

Dim query As String = "Select * from Table1"
Using con As New System.Data.OleDb.OleDbConnection(strAccessCon)
   Using accessadp As New System.Data.OleDb.OleDbDataAdapter(query, con)
      Dim ds As New DataSet()
      accessadp.Fill(ds, "Table1 Data")
      ds.SelectComamnd.CommandText = "Select * from Table2"
      accessadp.Fill(ds, "Table2 Data")
   End Using
End Using

Two commands in one works in Sql Server, but doesn't in Access.
