Question

我在cosmo db中定义了一个函数，定义如下。在编辑器中，查询有效，但是当我运行该函数时，它返回 500 Internal Server Error 。

在编辑器中查询没问题：

SELECT * FROM Trip c where ARRAY_CONTAINS(c.deliveries, {"currentDev": "1", "email": "punto1@mail.it"}, true)

在function.json中查询不起作用：

{
  "bindings": [
    {
      "authLevel": "function",
      "name": "req",
      "type": "httpTrigger",
      "direction": "in",
      "methods": [
        "get",
        "post"
      ],
      "route": "getRoutes/{emailpar}"
    },
    {
      "name": "$return",
      "type": "http",
      "direction": "out"
    },
    {
      "type": "cosmosDB",
      "name": "inDocuments",
      "databaseName": "cdb-01",
      "collectionName": "myCollection",
      "connectionStringSetting": "mpn_COSMOSDB",
      "direction": "in",
      "sqlQuery": "SELECT * FROM Trip c where ARRAY_CONTAINS(c.deliveries, {currentDev: '1', email: {emailpar}}, true)"
    }
  ]
}

我认为通过括号{}定义数组中要搜索的参数和对象是语法问题。

您需要对sql查询字符串的非参数字符串插值对象进行转义。您可以通过在每个引用中添加一个大括号来做到这一点。

这意味着您的查询字符串必须为：

SELECT * FROM Trip c where ARRAY_CONTAINS(c.deliveries, {{currentDev: '1', email: {emailpar}}}, true)

Azure函数ARRAY_CONTAINS中的SqlQuery不起作用
