| 18:50 | [284e1199] part of check-in [2978b65e] Always disallow the use of non-deterministic functions in CHECK constraints, even date/time functions that use the 'now' or similar keywords. Provide improved error messages when this requirement is not met. Ticket [830277d9db6c3ba1] (check-in: [2978b65e] user: drh branch: trunk, size: 16947) | |

2019-09-02
| ||
| 00:58 | [fb56f0b9] part of check-in [0658c16e] When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression. Ticket [57af00b6642ecd68]. (check-in: [0658c16e] user: drh branch: trunk, size: 16900) | |

2018-02-01
| ||
| 01:13 | [63526119] part of check-in [88e2ce91] When an index is based on a text representation of a numeric column in the original table, make sure the indexed value uses the canonical text representation of the numeric value in the table.

2015-09-05
| ||
| 22:36 | [4feec154] part of check-in [7ab0b258] Omit all use of Expr nodes for TK_AS, as those nodes no longer served a useful purpose and in fact interferred with the query planner. (check-in: [7ab0b258] user: drh branch: trunk, size: 8041) | |
