| 22:24 | Fix the sqlite3_table_column_metadata() routine so that it gives the correct answer for the "rowid" column in a WITHOUT ROWID table. Enhance it so that it can be used to check for the existence of a table by setting the column name parameter to NULL. The routine is now included in the build by default, even without the SQLITE_ENABLE_COLUMN_METADATA compile-time option. check-in: cf9be419 user: drh tags: trunk | |
