drh	bd462bcc10	Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows ... a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output.

drh	fa16f5d9d6	Enhance EXPLAIN QUERY PLAN to report the generation of constant rows using ... VALUES or just a SELECT without FROM. FossilOrigin-Name: c75eee69fa8a9b56ee58a4cc539e80cc982f43390dc3a357344d58479dd89a41	2018-05-03 01:37:13 +00:00
drh	b3f0276b9e	Fix test cases so that they work with the new EXPLAIN QUERY PLAN output ... format. Only some of the cases have been fixed. This is an incremental check-in. FossilOrigin-Name: 5f0e803e33aa557865d5fc830d9202d628de9a94c9757058ca48f1a560702cd3	2018-05-02 18:00:17 +00:00
