C#

Do you understand JOIN, grouping, and aggregate functions in SQL?

Have you been involved in database and system design? At what level?

There is a table Clients and a table Orders, which can be linked through the ClientId field. What JOINs should be written to obtain the following results? a. Records of all clients and orders, regardless of whether clients have orders select * from Clients left join Orders on Clients.ClientId = Orders.ClientId d. Records only about those clients and orders if clients have orders select * from Clients inner join Orders on Clients.ClientId = Orders.ClientId

What approaches and principles have you applied when working with code?

Are you more of a backend developer or a frontend developer?

d. Records only about clients and orders if clients have orders select * from Clients inner join Orders on Clients.ClientId = Orders.ClientId g. Clients with more than 10 orders select * from Clients inner join Orders on Clients.ClientId = Orders.ClientId
