Execution support for aggregation, cross joins #25

Closed mattdutson closed 5 years ago

mattdutson commented 5 years ago

Aggregate functions currently supported:

SUM
COUNT

These work end-to-end (cli through execution). GROUP BY clauses are not yet supported.

The execution engine can run queries such as SELECT a, w FROM T JOIN A. However, it appears that the optimizer requires all joins to have an ON clause, so these don't make it through the whole pipeline.

@johnchronis What's the command used by Travis to build and run tests? Build is failing on one of the execution tests.

johnchronis commented 5 years ago

In the buil folder you can use ctest --output-on-failure to run all the tests.

That is what Travis uses

LGTM. Merging.
