在Azure表存储中，是否可以使用.NET Core查询属性的子字符串？

Question

In my Azure Table I have a string property called "Labels" that looks something like this (A Json serialization of List):

["value1","value2","value3","value4"]

Is it possible to query the table for all the entries that contain the substring "value3" in the Labels property?

Answer 1

If you are looking for something like wildcard search eg message like '%SysFn%' , it is not feasible at this moment, You can find all the supported operations below

https://docs.microsoft.com/en-us/rest/api/storageservices/Querying-Tables-and-Entities?redirectedfrom=MSDN

Yes, you can filter by any attribute. However please keep in mind that only PartitionKey and RowKey are indexed so any query operation which doesn't include at least PartitionKey will result in full table scan. This will become an issue if your table contains lots of entities.

Hope it helps.
