| 14:54 | Back out the "--raw" option on ".read" in the command-line shell. Instead, fix the command-line shell so that if EOF is reached without seeing a final semicolon, it goes ahead and passes the accumulated SQL text to SQLite. (check-in: f98c8ac8c4 user: drh tags: trunk) | |
| 09:51 | Add extra tests for the xBestIndex() virtual table method. (check-in: 642a8fba91 user: dan tags: trunk) | |
