标题：请问这样写代码对吗?

Dim jb As New SQLJoinTableBuilder("查询表1","入库单")
jb.AddTable("入库单","入库单号","入库单明细","入库单号")
jb.AddCols("{入库单}.*")
Dim jd As New SQLJoinTableBuilder("查询表","销售订单")
jd.AddTable("销售订单","订单号","销售订单明细","订单号")
jd.AddCols("{入库单}.*")
Dim jf As New SQLJoinTableBuilder("查询表2","jb")
jf.AddTable("jb","订单号","jd","订单号")
jf.AddCols("{*}.*")

jf.build
MainTable = Tables("查询表1")

想请教一下,能不能用这样的格式,,,我的代码要求

Dim jb As new SQLJoinTableBuilder

Dim cb As new CrossTableBuilder

各用二次
