# Complex values

As always, you can provide a callback to the `set` method to get access
to an expression builder:

import {
  Playground,
  exampleSetup,
} from '../../../src/components/Playground'

import {
  complexValues
} from './0020-complex-values'

<div style={{ marginBottom: '1em' }}>
  <Playground code={complexValues} setupCode={exampleSetup} />
</div>

The API documentation is packed with examples. The API docs are hosted [here](https://kysely-org.github.io/kysely-apidoc/),
but you can access the same documentation by hovering over functions/methods/classes in your IDE. The examples are always
just one hover away!

For example, check out these sections:
 - [set method](https://kysely-org.github.io/kysely-apidoc/classes/UpdateQueryBuilder.html#set)
 - [returning method](https://kysely-org.github.io/kysely-apidoc/classes/UpdateQueryBuilder.html#returning)
 - [updateTable method](https://kysely-org.github.io/kysely-apidoc/classes/Kysely.html#updateTable)
