Question

在我的表中，对于重复的“行号”，我有不同的“承包商”，如下所示。

LINE NO     CONTRACTOR

L-0001      C-1000
L-0001      C-2000
L-0003      C-6000
L-0003      C-8000
L-0003      C-9000
L-0004      C-5000

现在我想查询如下所示的转置值：

LINE NO     CONTRACTOR1     CONTRACTOR2         CONTRACTOR3

L-0001      C-1000          C-2000
L-0003      C-6000          C-8000              C-9000
L-0004      C-5000

请帮助我如何进行此查询？

我做了一个查询，对我的表格数据进行排名如下：

  SELECT A.[line no], A.contractor, Count(*) AS ranking, "contractor" & [ranking] AS   contractor_rank
     FROM Table2 AS A INNER JOIN Table2 AS B ON (A.contractor>=B.contractor) AND (A.[line no] = B.[line no])
    GROUP BY A.[line no], A.contractor;

然后对顶部查询进行了交叉表查询，如下所示：

    TRANSFORM First(Query4.contractor) AS FirstOfcontractor
    SELECT Query4.[line no]
  FROM Query4
  GROUP BY Query4.[line no]
  PIVOT Query4.contractor_rank;

现在可行。
