# Query a Table in a Storage Tables

●

Published 2022-12-03

This tutorial explains how we can query a Storage Table in Azure.

Azure Table storage stores large amounts of structured data. The service is a NoSQL datastore which accepts authenticated calls from inside and outside the Azure cloud. Azure tables are ideal for storing structured, non-relational data.

A table is a collection of entities. Tables don't enforce a schema on entities, which means a single table can contain entities that have different sets of properties.

An entity is a set of properties, similar to a database row. An entity in Azure Storage can be up to 1MB in size. An entity in Azure Cosmos DB can be up to 2MB in size.

A property is a name-value pair. Each entity can include up to 252 properties to store data. Each entity also has three system properties that specify a partition key, a row key, and a timestamp. Entities with the same partition key can be queried more quickly, and inserted/updated in atomic operations. An entity's row key is its unique identifier within a partition.

Here is what we have :

a storage account named storageaccount90011 and a table named MyAzureTable2:
a Shared Access Signature (SAS) created for the tables in this Storage Account:

Now we need to query the "MyAzureTable2" table from Postman.

Here are the steps:

Take the Table service SAS URL from a SAS

https://storageaccount90011.table.core.windows.net/?sv=2021-06-08&ss=t&srt=s&sp=rwdlacu&se=2023-02-15T08:14:50Z&st=2023-02-13T23:14:50Z&spr=https&sig=ewX7nzKPlKOj7t8n%2BQEb4jerlprU5uXXy6BInEJ%2Bb5M%3D

Add the table name in Table service SAS URL The table name must be added between "/" and "?" signs, and we will obtain:

https://storageaccount90011.table.core.windows.net/MyAzureTable2?sv=2021-06-08&ss=t&srt=s&sp=rwdlacu&se=2023-02-15T08:14:50Z&st=2023-02-13T23:14:50Z&spr=https&sig=ewX7nzKPlKOj7t8n%2BQEb4jerlprU5uXXy6BInEJ%2Bb5M%3D

Copy in Postman the command above
Run the request as a GET request

And you will receive a response body like this:

<?xml version="1.0" encoding="utf-8"?>

        <content type="application/xml">
            <m:properties>
                <d:PartitionKey>mypartitionkey1</d:PartitionKey>
                <d:RowKey>myrowkey1</d:RowKey>
                <d:Timestamp m:type="Edm.DateTime">2023-02-14T18:18:15.9990469Z</d:Timestamp>

            </m:properties>
        </content>
    </entry>
</feed>

As you can see there is only one entity in this table.
