I fixed a bug that `sqlite-utils transform` breaks DEFAULT values. All tests already present passed with no changes, and I added some tests for this PR. In #509 case, fixed here. ```shell $ sqlite3 test.db << EOF CREATE TABLE mytable ( col1 TEXT DEFAULT 'foo', col2 TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) ) EOF $ sqlite3 test.db ""SELECT sql FROM sqlite_master WHERE name = 'mytable';"" CREATE TABLE mytable ( col1 TEXT DEFAULT 'foo', col2 TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) ) $ sqlite3 test.db ""INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;"" foo|2022-12-21 01:15:39.669 $ sqlite-utils transform test.db mytable --rename col1 renamedcol1 $ sqlite3 test.db ""SELECT sql FROM sqlite_master WHERE name = 'mytable';"" CREATE TABLE ""mytable"" ( [renamedcol1] TEXT DEFAULT 'foo', [col2] TEXT DEFAULT (STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW')) # ← Non-String Value ) $ sqlite3 test.db ""INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;"" foo|2022-12-21 01:15:39.669 foo|2022-12-21 01:15:56.432 ``` And #336 case also fixed. Special values are described [here](https://www.sqlite.org/lang_createtable.html). > 3.2. The DEFAULT clause > ... A default value may also be one of the special case-independent keywords CURRENT_TIME, CURRENT_DATE or CURRENT_TIMESTAMP. ```shell $ echo 'create table bar (baz text, created_at timestamp default CURRENT_TIMESTAMP)' | sqlite3 foo.db $ sqlite3 foo.db SQLite version 3.39.5 2022-10-14 20:58:05 Enter "".help"" for usage hints. sqlite> .schema bar CREATE TABLE bar (baz text, created_at timestamp default CURRENT_TIMESTAMP); sqlite> .exit $ sqlite-utils transform foo.db bar --column-order baz $ sqlite3 foo.db SQLite version 3.39.5 2022-10-14 20:58:05 Enter "".help"" for usage hints. sqlite> .schema bar CREATE TABLE IF NOT EXISTS ""bar"" ( [baz] TEXT, [created_at] FLOAT DEFAULT CURRENT_TIMESTAMP ); sqlite> .exit $ sqlite-utils transform foo.db bar --column-order baz $ sqlite3 foo.db SQLite version 3.39.5 2022-10-14 20:58:05 Enter "".help"" for usage hints. sqlite> .schema bar CREATE TABLE IF NOT EXISTS ""bar"" ( [baz] TEXT, [created_at] FLOAT DEFAULT CURRENT_TIMESTAMP # ← Non-String Value ); ``` ---- :books: Documentation preview :books:: https://sqlite-utils--519.org.readthedocs.build/en/519/ ",140912432,pull,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/519/reactions"", ""total_count"": 3, ""+1"": 3, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0,
