| 20:59 | Make sure that the KeyInfo.nXField value of ephermeral tables used for ORDER BY and GROUP BY is set correctly, so that the correct comparison function can be choosen by sqlite3VdbeFindCompare(). check-in: c16bae5e user: drh tags: tkt-f97c4637 | |

| 19:48 | An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters. check-in: bf744b49 user: drh tags: tkt-f97c4637 | |
