Dim cmd As New SQLCommand
Dim ld As DataTable
cmd.C
cmd.CommandText = "查询 Distinct  {销售单}.物料编号 AS 物料编号 From {销售单} "
ld = cmd.ExecuteScalar()

如何将外部表查询结果转化为文本集合，结构{"ABZ001","ABZ002","ABZ003","ABZ004","ABZ005"}
可以在另外的内部查询表中使用  “查询 Distinct  {销售表}.物料编号 AS 物料编号 From {销售表}  where {销售表}.物料编号 in ("& ld &")”

Dim cmd As New SQLCommand
Dim ld As DataTable
cmd.C
cmd.CommandText = "select Distinct 物料编号 From {销售单} "
ld = cmd.ExecuteReader()
Dim lst As List(of String) = ld.GetValues("物料编号")

dim sql as string = “select  Distinct   物料编号 From {销售表}  where 物料编号 in (\'" & String.Join("\',\'",l st.ToArray) & "\')”
