In #SQL it is possible to retrieve all data from a data store by telling the query engine to select *, where * is shorthand for everything. This is harmful not just because it slows down processing compared to selecting exactly what you need, but also because some query engines fail to update dependencies automatically. So if your greedy query depends on a specific one which then removes a field, yours will fail to run until you recreate it.
