Richard Newman	74f188df9b	Part 5b: rename also/instead to add_intersection and add_alternate.	2017-03-30 19:13:20 -07:00
Richard Newman	9e5c735460	Part 5: split cc.rs into a 'clauses' module. ... mod.rs defines the module and ConjoiningClauses itself, complete with methods to record facts and ask it questions. pattern.rs, predicate.rs, resolve.rs, and or.rs include particular functionality around accumulating certain kinds of patterns. Only `or.rs` includes significant new code; the rest is just split.	2017-03-30 19:13:20 -07:00

Richard Newman	997df0b776	Part 1: introduce ColumnIntersection and ColumnAlternation. ... This provides a limited form of OR and AND for column constraints, allowing simple 'or-join' queries to be expressed on a single table alias.	2017-03-30 19:13:19 -07:00
