You may retrieve multiple entities by utilizing LINQ with Storage Consumer Library and specifying a question with a where by clause. In order to avoid a table scan, you'll want to constantly involve the PartitionKey benefit from the exactly where clause, and if possible the RowKey value in order to avoid table and partition scans. The table service supports a minimal set of comparison operators (increased than, greater than or equivalent, below, a lot less than or equivalent, equal, and never equivalent) to work with from the exactly where clause.
com') For those who question for An array of employee entities, you can specify a variety sorted in employee id purchase, or a spread sorted in electronic mail deal with order by querying for entities with the right prefix in the RowKey.

This visit this web-site segment focuses on tips on how to translate several of the widespread connection varieties located in area designs to layouts for your Table assistance.
For more information about working with many entity styles you can try here in precisely the same table in consumer code, see the part Working with heterogeneous entity forms later On this guide. This presents examples of how to acknowledge the entity type in shopper code. Table Structure Patterns
Observe that to retrieve other Houses you must make use of the TryGetValue approach to the Houses property in the DynamicTableEntity course.
