Loading Taxi Data into Google Cloud SQL 2.5 Reviews

It seems extraordinary to deal with table defs and similar DDL on a naked CLI. Probably more people would use a SQL client. Task 2 - #13 and Task 4 #2: Parentheses around the DISTINCT columns are unnecessary and perhaps misleading in so far as they may create the impression of a function (DISTINCT is not a function). Given: select distinct(pickup_location_id) from trips; Better: SELECT DISTINCT pickup_location_id FROM trips; Even better: SELECT COUNT(DISTINCT pickup_location_id) AS distinct_ids FROM trips; (Note that AS is optional - it's helpful for people who may be new to SQL)

Zu wenig Zeit (um alle Inhalte die für einen Tag eingeplant sind zu schaffen, ist man effektiv auf 30 Minuten eingeschränkt). Das Lab reduziert sich auf Copy & Paste Aktionen, ohne dass man genaueres Verständnis erlangt, was und warum ausgerechnet so, man tut.
