Question

I’m trying to implement a query for one of my Azure Tables, the query should retrieve all files that contain the input string.

I’ve tried using string.contains() but this isn’t supported by Azure, I’ve also tried string.startswith() this also isn’t supported.

What I’m wondering is if there is a way to do this in Azure Tables. I’m storing file information in the tables and the partition key is the virtual path of the item stored.

e.g. Images_Jpg_Image1.jpg would be a partition key for one of the files, i’ve used ‘_’ because Azure won’t allow ‘/’ in partition keys.

I’d like to be able to compare the above partition key with

Ideally the following strings would return that partition key

Images_
Images_Jpg
Jpg_
Image1.jpg

I have all the tables set up and all of the other queries, its just this one query that I can’t figure out.

Thanks in advance for any help,

Matt

Answer 1

Table Storage does support the CompareTo method which can be used like a StartsWith. But it still might not work for you based on the types of searching you’re trying to do.

MyTable.Where(t => t.PartitionKey.CompareTo("image") >= 0).ToList();
