Our team found sqlite-utils through @simonw's [comment on the "Simple declarative schema migration for SQLite" article](https://news.ycombinator.com/item?id=31249823), and we were excited to use it, but unfortunately `sqlite-utils transform` seems to break our DB. Running `sqlite-utils transform` to modify a column mangles their DEFAULT values: - Default string values are wrapped in extra single quotes - Function expressions such as [`STRFTIME()`](https://www.sqlite.org/lang_datefunc.html) are turned into strings! ------ Here are steps to reproduce: **Original database** ``` $ 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')) ) ``` **Modified database after sqlite-utils** ``` $ sqlite3 test.db "INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;" foo|2022-11-02 02:26:58.038 $ 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'')' ) $ sqlite3 test.db "INSERT INTO mytable DEFAULT VALUES; SELECT * FROM mytable;" foo|2022-11-02 02:26:58.038 'foo'|STRFTIME('%Y-%m-%d %H:%M:%f', 'NOW') ``` (Related: #336) | 140912432 | issue | { "url": "https://api.github.com/repos/simonw/sqlite-utils/issues/509/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |
