Hi all ,
i use vb.net and already fill dataset.table in form load. If i want to use sql statement to filter dataset's data using sql statement ,
select distinct[sysname] from funclib left outer join syslib on funclib.sysid = syslib.sysid , i know select database data in dataset , but
i don't know select dataset data and using sql statement to do something , how can i do, thank you ?

Private Sub FuncLib_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.SyslibTableAdapter.Fill(Me.WilsonDataSet.syslib)
Me.FunclibTableAdapter.Fill(Me.WilsonDataSet.funclib)
End Sub
