From: drh Date: Fri, 17 Feb 2017 13:38:15 +0000 (+0000) Subject: Enhance the Index and Table objects so that they remember if their stats come X-Git-Tag: version-3.18.0~81^2~15 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=33bec3f5e89787125b56243ab7de2fe9353b8b8a;p=thirdparty%2Fsqlite.git Enhance the Index and Table objects so that they remember if their stats come from the sqlite_stat1 table. Make the "PRAGMA stats" an SQLITE_DEBUG only pragma. Add the flags column to "PRAGMA stats". These are all preliminary steps toward a "PRAGMA analyze_ifneeded;" feature.
