Question

如果有3个拒绝代码，则当前查询为一个发票返回3行，如果有多个拒绝代码和多个拒绝日期，则返回更多。我正在尝试为每个拒绝代码创建一个列，以便所有结果都可以在一行上。客户端的要求是每个拒绝都在它自己的列中，所以我无法使用listagg函数。结果应如下所示：

办公室，发票，拒绝日期，拒绝代码1，拒绝代码2，拒绝代码3，拒绝日期2，拒绝代码1 ......等等

Oracle数据库。目前的代码：

                 SELECT
                 A.OFFICE_NBR,
                 A.INV_NBR,
                 TO_DATE(A.CRTD_DT,'MM/DD/YYYY') AS CARC_DT,
                 A.CLM_ID,
                 A.CLM_LN_ID,
                 A.RSN_CD

                 FROM DENIALS A
                 WHERE A.OFFICE_NBR = '1234'
                 AND A.INV_NBR = '123456'

我猜测了一些测试数据，但这应该可以帮到你。请添加一些前后数据，这有助于了解您尝试做什么，并允许构建更现实的解决方案。

无论如何，需要注意的是，您必须提前为每个可能的拒绝代码定义DENIAL_CD_X列。我将有兴趣看看是否有人可以为denial_cd列提出动态解决方案。
