| 15:41 | Continuing incremental enhancements of SELECT code generation: Remove the Select.affinity field. Use SelectDest.affSdst instead. (check-in: cf40b7b5eb user: drh tags: trunk) | |
| 14:26 | Refactoring of DISTINCT code. Change the name of the local variable "distinct" to "distinctTab". Generate cleaner code w/o unnecessary P4 and P5 values on the OP_Null for WHERE_DISTINCT_ORDERED. (check-in: 0cda241a2b user: drh tags: trunk) | |

| 13:29 | Factor out the code that generates a co-routine for evaluating the SELECT on the RHS of an INSERT statement so that the same code can potentially be reused in other places. (check-in: a93ee09cdc user: drh tags: trunk) | |
