Different approaches to represent a structure in the projection part of a
SELECT.
**BigQuery syntax:**
`STRUCT('Bob' AS name, 38 AS age) AS users`
`STRUCT<name string, age integer>('Bob', 50) as user // syntax to
specify explicitly the type of each field`
**Spark syntax:**
`NAMED_STRUCT('name', 'Bob', 'age', 50) as users`
**Postgres and Athena syntax:**
`CAST(ROW('Bob', 38) AS ROW(name VARCHAR, age INTEGER)) AS users`
**Snowflake syntax:**
`OBJECT_CONSTRUCT('name', 'Bob'::VARCHAR, 'age', 50::INTEGER)`
