| 20:35 | [6d817c28a8] part of check-in [5822feec43] The number of declared columns in an index is limited to SQLITE_LIMIT_COLUMN. But the actual number of columns in the implementation might need to be twice as much to account for the primary key at the end. Ensure that the code is able to deal with this. This is a correction to check-in [d7729dbbf231d57c]. (check-in: [5822feec43] user: drh branch: trunk, size: 7334) | |
| 17:03 | [b963c1e8c4] part of check-in [d7729dbbf2] Detect when a UNIQUE or PRIMARY KEY on a WITHOUT ROWID table would need to use more than SQLITE_LIMIT_COLUMN columns and raise an error. Also include some unrelated compiler warning fixes. (check-in: [d7729dbbf2] user: drh branch: trunk, size: 7014) | |
