编辑中、订单编号是字符列?
Dim t As Table = Tables("出货主表")
Dim cmd As New SQLCommand
cmd.C
Dim exp As String = "编辑中 is null And [订单编号] = '" & t.Current("订单编号") & "'"
MessageBox.Show(t.Current("订单编号"))
cmd.CommandText = "Update {出货主表} Set 编辑中 = '" & t.Current("订单编号") & "' Where " & exp
Dim Count As Integer = cmd.ExecuteNonQuery()
Messagebox.Show( "总共修改" & Count & "行!")
