| 14:05 | Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly. These changes are already in the rowvalue branch but are added here since they are technically unrelated to rowvalue. (check-in: 4d43c469 user: drh tags: trunk) | |
