0.15.1

Fix a bug in returningAll return type when using ColumnType.

0.15.0

• New ColumnType and Generated interfaces for defining separate interfaces for select, insert and update operations. See the example in the readme for more info.

Breaking changes

• The db.migrate module has been removed. You now need to create an instance of Migrator instead.
• The new Generated interface removes the need for db.generated which has now been removed. Simply mark your db-generated columns with Generated<T> in the table interface and remove db.generated.

Before:

interface Person {
  id: number,
  first_name: string
}
await db.insertInto('person').values({
  id: db.generated,
  first_name: 'Jennifer'
})

Now:

interface PersonTable {
  id: Generated<number>,
  first_name: string
}
type Person = Selectable<PersonTable>
await db.insertInto('person').values({
  first_name: 'Jennifer'
})

0.14.1

Removed a magical UnionToIntersection type that made it difficult to write generic helpers.

0.14.0

• Kysely now supports all the features of SQLite on conflict clause (almost all features of the PostgreSQL on conflict clause)

Breaking changes

• All expression methods in the schema module previously took a raw SQL string. Those all now take a db.raw instance instead for consistency.

// Before
db.schema
  .alterTable('person')
  .addCheckConstraint('some_constraint', 'a < b')

// Now
db.schema
  .alterTable('person')
  .addCheckConstraint('some_constraint', db.raw('a < b'))

• onConflictDoNothing and onConflictUpdate methods have been replaced by a single onConflict method.

// Before
db.insertInto('pet').values(pet).onConflictUpdate('name', updates)

// Now
db.insertInto('pet').values(pet).onConflict(
  // Also see the `columns` and `constraint` methods.
  (oc) => oc.column('name').doUpdateSet(updates)
)

// Before
db.insertInto('pet').values(pet).onConflictDoNothing('name')

// Now
db.insertInto('pet').values(pet).onConflict(
  (oc) => oc.column('name').doNothing()
)

0.13.0

• Added migrateTo, migrateUp and migrateDown methods.
• Added unsigned method for creating unsigned integer columns on MySQL.

Breaking changes

• migrateToLatest no longer throws. The error is returned instead. See the return value type documentation for more info.

0.12.2

• Added withRecursive for recursive common table expressions.
• Support node 14. Kysely will support the last two LTS versions from now on.

0.12.1

Make jsdoc comments better accessible by copying them from the interfaces to the implementing classes. This is done automatically as a build step.

0.12.0

• Added support for temporary tables
• Added support for insert into select from queries

Breaking changes

• Renamed the subQuery method to selectFrom.
• Created separate query builders for select, insert, update and delete queries. This is only a breaking change if you have used the QueryBuilder type explicitly.

0.11.4

Support callback subqueries and raw expressions in insert queries:

db.with('jennifer', (db) => db
  .selectFrom('person')
  .where('first_name', '=', 'Jennifer')
  .select(['id', 'first_name'])
  .limit(1)
).insertInto('pet').values({
  id: db.generated,
  owner_id: (eb) => eb.subQuery('jennifer').select('id'),
  name: (eb) => eb.subQuery('jennifer').select('first_name'),
  species: 'cat',
})

0.11.3

Support custom log function:

const db = new Kysely<Database>({
  dialect: new PostgresDialect(postgresConfig),
  log(event) {
    if (event.level === 'query') {
      console.log(event.query.sql)
      console.log(event.query.parameters)
    }
  }
})
