查询以从 Cosmos DB 获取详细信息

Question

I need to fetch the list of persons from an array(Ex: String[] getPersons ) as input. I can't figure out how to compare and fetch data from Cosmos DB using a LINQ expression. I experimented with GetItemLinqQueryable , but I don't know if it's the right way to use it.

var db = Client.GetDatabase(databaseId);

var container = db.GetContainer(containerId);

var q = container.GetItemLinqQueryable<Person>();

var iterator = q.Where(p => p.Name == getPersons[0]).ToFeedIterator();

var results = await iterator.ReadNextAsync();

If I am using the above one, I could only able to get only the first person result but I need to get the other persons in the array as well.

Answer 1

You can use Contains. It is equivalent to ARRAY_CONTAINS in Cosmos DB Array functions.

You can try this code:

var iterator = q.Where(p => getPersons.Contains(p.Name)).ToFeedIterator();
