Projection

selects all of the variables that are in-scope at that point in the query. It excludes variables only used in FILTER, in the right-hand side of MINUS, and takes account of subqueries.

-

Use of SELECT * is only permitted when the query does not have a - GROUP BY clause.

+

Use of SELECT * is only permitted when the query does not use grouping + (either through the use of a GROUP BY clause, or due to the presence of aggregates + in HAVING or ORDER BY clauses).
