- Base cases:
- 1. ast is null => null
- 2. ast is aggregate_function(table.column) => add aggregate_function(table.column) to inner select expressions,
- generate alias, return aggregate_function(cube.alias). Memoize the mapping
- aggregate_function(table.column) => aggregate_function(cube.alias)
- Assumption is aggregate_function is transitive i.e. f(a,b,c,d) = f(f(a,b), f(c,d)). SUM, MAX, MIN etc
- are transitive, while AVG, COUNT etc are not. For non-transitive aggregate functions, the re-written
- query will be incorrect.
- 3. ast has aggregates - iterate over children and add the non aggregate nodes as is and recursively get outer ast
- for aggregate.
- 4. If no aggregates, simply select its alias in outer ast.
- 5. If given ast is memorized as mentioned in the above cases, return the mapping.
