When we split ProtocolModificationDynamicData there were 2 values which were translated into 2 rows from 1 row. You can use values from JSON text in any part of a Transact-SQL query (including WHERE, ORDER BY, or GROUP BY clauses, window aggregates, and so on). After you restore the sample database to an instance of SQL Server, extract the samples file, and then open the JSON Sample Queries procedures views and indexes.sql file from the JSON folder. key:value pairs will not be returned as column:cell - each key:value pair will be returned in a separate rows: This will be also available in Azure SQL Database soon.
