| 23:52 | When the left table of a RIGHT JOIN is used inside an aggregate function and the left table employs an index on expressions, then make sure the expressions evaluate to NULL for the cases where the left table should be NULL. Fix for forum post 9b491e1deb. (check-in: ffe23af7 user: drh tags: trunk) | |
| 23:40 | Add usage detection to the NULL value generator for the left table of a RIGHT JOIN inside of an aggregate. (Closed-Leaf check-in: 4d05a009 user: drh tags: rightjoin-agg-idxexpr) | |

| 21:01 | When the left table of a RIGHT JOIN is used inside an aggregate function and the left table employs an index on expressions, then make sure the expressions evaluate to NULL for the cases where the left table should be NULL. Proposed fix for forum post 9b491e1deb. More testing an analysis needed - there is a FIXME in this check-in. (check-in: 3572b40a user: drh tags: rightjoin-agg-idxexpr) | |
| 19:46 | In the byte-code generator, when the result of an expression needs to be in a particular register, always use the sqlite3ExprCode() routine because it has the smarts to know whether to use OP_Copy or OP_SCopy. Do not try to OP_SCopy inline because an OP_Copy might be required. (check-in: 2d439ccc user: drh tags: branch-3.41) | |
