-- Allow `kind = 'set_price'` on discount_codes (added at the daemon
|
|
-- level in v0.1.0:26 but the migration that created the CHECK constraint
|
|
-- in 0004 didn't include it, so existing instances reject the new kind
|
|
-- with "CHECK constraint failed").
|
|
--
|
|
-- SQLite doesn't support ALTER TABLE ... DROP CONSTRAINT, so we rebuild
|
|
-- the table: copy → drop old → rename. sqlx-migrate already wraps each
|
|
-- .sql file in a transaction, so we DON'T do BEGIN/COMMIT here (nested
|
|
-- transactions are not supported in SQLite).
|
|
--
|
|
-- `PRAGMA defer_foreign_keys = 1` is the transaction-local equivalent
|
|
-- of `foreign_keys = OFF`: it postpones FK constraint checks until
|
|
-- COMMIT time. This lets us drop the old discount_codes table without
|
|
-- the immediate FK check from discount_redemptions.code_id failing.
|
|
-- The IDs are preserved across the rebuild, so when the FK check runs
|
|
-- at COMMIT, every referencing row still resolves cleanly.
