| 20:43 | The NGQP might not find a solution if INDEXED BY constraints on the query are set wrong. If that is the case, print a "no query solution" error and abort before trying to use the non-existant solution. (check-in: 42511a7e12 user: drh tags: nextgen-query-plan-exp) | |

| 17:43 | Cut over the NGQP query planner. Remove lots of legacy code. This check-in compiles but does not work. The test suite gets incorrect answers and crashes. (check-in: 001539df4b user: drh tags: nextgen-query-plan-exp) | |
