| 15:40 | Add support for TRUE and FALSE keywords and for operators IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE. If there is are columns named TRUE or FALSE, then the keywords resolve to the column names, for compatibility. The behavior of the "DEFAULT true" phrase is changed to mean what it says, rather than being an alias for "DEFAULT 'true'". check-in: 9a7f02c5 user: drh tags: trunk | |
