Azure 逻辑应用在 SQL 连接上失败

Question

我正在尝试调用 Azure 逻辑应用程序中的存储过程。但是，每当我尝试连接到 DB & select 过程或执行应用程序时，我都会收到以下错误。

`

{
  "status": 400,
  "message": "Can not add property StartTime to Newtonsoft.Json.Linq.JObject. Property with the same name already exists on object.\r\nclientRequestId: 99825289-bbe8-4b91-8323-075e8cacd09c",
  "source": "sql-logic-cp-centralindia.logic-ase-centralindia.p.azurewebsites.net"
}

`

如果尝试执行 SQL select 查询而不是存储过程，我会遇到同样的错误。

这是逻辑应用程序的代码。有什么建议么？

}

Answer 1

好吧，这是一个棘手的错误。经过一番斗争，我能够弄清楚这个问题。在我的 select 查询中，我有两个同名的字段。这导致了创建输出 JSON 的问题。

我在查询中有两个字段，如下所示

Select .. SM.StartTime,... SS.StartTime from tables .. joins

SQL 输出在 SQL 输出中有两次 StartTime。所以我添加了一个别名如下，它解决了这个问题。

Select .. SM.StartTime,... SS.StartTime as SessionStartTime from tables .. joins
