1173049178 PR_kwDOCGYnMM5F609a 519 closed 0 Fixes breaking DEFAULT values 13819005 Fixes #509, Fixes #336 Thanks for the great library! 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 ); ``` <!-- readthedocs-preview sqlite-utils start --> ---- :books: Documentation preview :books:: https://sqlite-utils--519.org.readthedocs.build/en/519/ <!-- readthedocs-preview sqlite-utils end --> 2022-12-21T01:27:52Z 2023-05-08T21:13:37Z 2023-05-08T21:13:37Z 2023-05-08T21:13:37Z 6500fed8b2085869b9714ce3a08c30f61dc829ad     0 5e5c262fab69eb3c470afa57fc52d3d7d8beee7a fc221f9b62ed8624b1d2098e564f525c84497969 CONTRIBUTOR 140912432 https://github.com/simonw/sqlite-utils/pull/519
