This article is a case study on writing a complex query on an SQL database. We start with a set of database tables, populated with data. We then have a requirement to show some data by writing a query. We’ll write the query step-by-step and get to our final result. You’ll see...
Example See medications found in the MedicationStatement resource type The following example query shows you how to organize the nested JSON imported into Athena using SQL.

If you copy the formula to another worksheet, it is best to do this via the edit bar. Then you have to adjust the worksheet names and cell C29 once. That was just an example. So adjust the C29 by the cell in which the formula is located. If you use it in C1, you must rep...
Complex types can be projected from a query. For example, selecting just the shipping address from an order: Copy var shippingAddress = await context.Orders .Where(e => e.Id == orderId) .Select(e => e.ShippingAddress) .SingleAsync(); This translates to the following when using SQL Ser...
In the following example, an open connection to the AdventureWorks2022 sample database is passed in to the function, a complex statement is constructed that combines a stored procedure call with a SQL statement, the statements are run, and then adoloop is used to process all the result sets ...
