| 19:07 | Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. check-in: 4f7549ff user: drh tags: trunk | |
