node.js - Cosmos DB 通过部分文档更新进行增量

Question

https://learn.microsoft.com/en-us/azure/cosmos-db/partial-document-update#supported-operations说我可以使用“increment”来增加数据库中的值，但是这段代码

const operations =
          [
              { op: 'increment', path: '/public/inventory/irradish', value:  irradish},
              { op: 'increment', path: '/public/inventory/sunmelon', value:  sunmelon},
              { op: 'set', path: '/map/garden/lastUse', value:  time}
          ];
          const { resource: updated } = await container
          .item(
              id = email, 
              partitionKeyValue = email
          )

抛出此错误:

错误:消息:{“错误”:[“补丁请求中的补丁操作'op'属性值无效:'增量'”]}ActivityId:f1bb8b88-ab68-4f2b-b244-8b021b0d9021，...

如何增加？

Answer 1

您需要使用上面回答的“incr”。

但是对于文档来说，增量只是一个操作。 Node SDK中的样本存储库说明了如何进行增量操作，

const multipleOperations: PatchOperation[] = [
      {
        op: "add",
        path: "/aka",
        value: "MeFamily",
      },
      {
        op: "replace",
        path: "/lastName",
        value: "Jose",
      },
      {
        op: "remove",
        path: "/parents",
      },
      {
        op: "set",
        path: "/address/zip",
        value: 90211,
      },
      {
        op: "incr",
        path: "/address/zip",
        value: 5,
      },
    ];
    const { resource: patchSource2 } = await container.item(patchId!).patch(multipleOperations);
    if (patchSource2) {
      console.log(`Patched ${JSON.stringify(patchSource)} to new ${JSON.stringify(patchSource2)}.`);
    }
