-- Drop the `favorite` column from the `ciphers` table, using the 12-step
-- procedure from <https://www.sqlite.org/lang_altertable.html#altertabrename>.
-- Note that some steps aren't applicable and are omitted.
-- 1. If foreign key constraints are enabled, disable them using PRAGMA foreign_keys=OFF.
--
-- Diesel runs each migration in its own transaction. `PRAGMA foreign_keys`
-- is a no-op within a transaction, so this step must be done outside of this
-- file, before starting the Diesel migrations.
-- 2. Start a transaction.
--
-- Diesel already runs each migration in its own transaction.
-- 4. Use CREATE TABLE to construct a new table "new_X" that is in the
-- desired revised format of table X. Make sure that the name "new_X" does
-- not collide with any existing table name, of course.
CREATE TABLE new_ciphers(

organization_uuid TEXT REFERENCES organizations(uuid),
atype INTEGER NOT NULL,
name TEXT NOT NULL,
notes TEXT,
fields TEXT,
data TEXT NOT NULL,
password_history TEXT,

-- 5. Transfer content from X into new_X using a statement like:
-- INSERT INTO new_X SELECT ... FROM X.
INSERT INTO new_ciphers(uuid, created_at, updated_at, user_uuid, organization_uuid, atype,
name, notes, fields, data, password_history, deleted_at)
SELECT uuid, created_at, updated_at, user_uuid, organization_uuid, atype,
name, notes, fields, data, password_history, deleted_at
FROM ciphers;
-- 6. Drop the old table X: DROP TABLE X.
DROP TABLE ciphers;
-- 7. Change the name of new_X to X using: ALTER TABLE new_X RENAME TO X.
ALTER TABLE new_ciphers RENAME TO ciphers;
-- 11. Commit the transaction started in step 2.
-- 12. If foreign keys constraints were originally enabled, reenable them now.
--
-- `PRAGMA foreign_keys` is scoped to a database connection, and Diesel
-- migrations are run in a separate database connection that is closed once
-- the migrations finish.
