18:20 | Fix a problem causing an INDEXED BY specifying an unusable partial index to be mishandled. (check-in: 292a04086a user: dan tags: trunk) | |
16:54 | Add the --trace option to the sqlite3_checker utility program. (check-in: dc217b7cfe user: drh tags: trunk) | |
16:23 | Enhance the checkindex.c virtual table so that it will output the index_name and after_key parameters. Also add a new diagnostic output column named scanner_sql which shows the SQL statement used to implement the current index scan. (check-in: 32e2520ce9 user: drh tags: trunk) | |
