* Add the SQLITE_INDEX_SCAN_HEX bit to the sqlite3_index_info.idxFlags bitmask.drh2024-08-22
| | | | | | When set, this bit causes the EXPLAIN QUERY PLAN output to show the idxNum value in hex rather than in decimal. This is purely a debugging aid. FossilOrigin-Name: 6c00e88ebdb41d6317bb8758825521614dedc2e6e6289ff415c5f0406eed815b
