Default non-NULL values copied from a column that was added using "ALTER TABLE ... ADD COLUMN ... DEFAULT ..." are inserted into another table as NULLs when copied using "INSERT INTO ... SELECT * FROM ..."
However, the same values are propagated correctly when "CREATE TABLE ... AS SELECT * FROM ..." is executed. See example below: $ sqlite3 SQLite version 3.8.4.3 2014-04-03 16:53:12 Enter ".help" for usage hints. Connected to a transient in-memory database.
