## New Features
|
|
|
|
### 🎉 `$onUpdate` functionality for PostgreSQL, MySQL and SQLite
|
|
|
|
Adds a dynamic update value to the column.
|
|
The function will be called when the row is updated, and the returned value will be used as the column value if none is provided.
|
|
If no `default` (or `$defaultFn`) value is provided, the function will be called when the row is inserted as well, and the returned value will be used as the column value.
|
|
|
|
> Note: This value does not affect the `drizzle-kit` behavior, it is only used at runtime in `drizzle-orm`.
|
|
|
|
```ts
|
|
const usersOnUpdate = pgTable('users_on_update', {
|
|
id: serial('id').primaryKey(),
|
|
name: text('name').notNull(),
|
|
updateCounter: integer('update_counter').default(sql`1`).$onUpdateFn(() => sql`update_counter + 1`),
|
|
updatedAt: timestamp('updated_at', { mode: 'date', precision: 3 }).$onUpdate(() => new Date()),
|
|
alwaysNull: text('always_null').$type<string | null>().$onUpdate(() => null),
|
|
});
|
|
```
|
|
|
|
