Question

我在ArcGIS的arcpy模块中使用python函数，名为“MakeQueryTable”。

http://pro.arcgis.com/en/pro-app/tool-reference/data-management/make-query-table.htm

基本上，它利用Oracle sql查询来构建表。我已经构建了一个脚本，我收到以下错误：

[ORA-00907：缺少右括号]

首先，我已经排队了，但似乎没有任何缺失的括号。再次，在换行并注释掉每一行并执行脚本以查看问题首次出现之后，似乎在我取消注释group by语句并删除LISTAGG语句之后发生。因此，当我删除group by语句并将LISAGG函数的行更改为["MTA.MTA_WORK_TYPE_ITEM_CODE.DESCRIPTION, ''Work_Type_Items']时，脚本将运行。当我允许group by语句时，脚本会抛出此错误。

不幸的是，我需要group by语句来生成我需要的表。 LISTAGG功能还依赖于分组才能正常运行。如果我要在Oracle SQL Developer中构建相同的查询，它将运行。我只是觉得我来这里看看有没有更好的SQL背景的人能否提出为什么会出现这个错误。

这是脚本：

tableList = ["MTA_SPATIAL.MTA_ACQUIRED_TENURE_SVW", "MTA.MTA_TENURE_EVENT_XREF", "MTA.MTA_EVENT", "MTA.MTA_SOW_EVENT", "MTA.MTA_SOW_WORK_TYPE_XREF", "MTA.MTA_WORK_TYPE_CODE", "MTA.MTA_WORK_TYPE_ITEM_CODE"]

fieldList = [["MTA_SPATIAL.MTA_ACQUIRED_TENURE_SVW.TENURE_NUMBER_ID", 'Tenure_Number'],
             ["MTA.MTA_EVENT.EVENT_NUMBER_ID", 'Event_Number'],
