+     * Access an element of a JSON array in a specific location.
+     *
+     * Since there's no guarantee an element exists in the given array location, the
+     * resulting type is always nullable. If you're sure the element exists, you
+     * should use {@link SelectQueryBuilder.$assertType} to narrow the type safely.
+     *
+     * See also {@link key} to access properties of JSON objects.
+     *
+     * ### Examples
+     *
+     * ```ts
+     * await db.selectFrom('person')
+     *   .select(eb =>
+     *     eb.ref('nicknames', '->').at(0).as('primary_nickname')
+     *   )
+     *   .execute()
+     * ```
+     *
+     * The generated SQL (PostgreSQL):
+     *
+     * ```sql
+     * select "nicknames"->0 as "primary_nickname" from "person"
+     *```
+     *
+     * Combined with {@link key}:
+     *
+     * ```ts
+     * db.selectFrom('person').select(eb =>
+     *   eb.ref('experience', '->').at(0).key('role').as('first_role')
+     * )
+     * ```
+     *
+     * The generated SQL (PostgreSQL):
+     *
+     * ```sql
+     * select "experience"->0->'role' as "first_role" from "person"
+     * ```
+     *
+     * You can use `'last'` to access the last element of the array in MySQL:
+     *
+     * ```ts
+     * db.selectFrom('person').select(eb =>
+     *   eb.ref('nicknames', '->$').at('last').as('last_nickname')
+     * )
+     * ```
+     *
+     * The generated SQL (MySQL):
+     *
+     * ```sql
+     * select `nicknames`->'$[last]' as `last_nickname` from `person`
+     * ```
+     *
+     * Or `'#-1'` in SQLite:
+     *
+     * ```ts
+     * db.selectFrom('person').select(eb =>
+     *   eb.ref('nicknames', '->>$').at('#-1').as('last_nickname')
+     * )
+     * ```
+     *
+     * The generated SQL (SQLite):
+     *
+     * ```sql
+     * select "nicknames"->>'$[#-1]' as `last_nickname` from `person`
+     * ```

+     *
+     * See also {@link at} to access elements of JSON arrays.
+     *
+     * ### Examples
+     *
+     * ```ts

+     *   eb.ref('address', '->').key('city').as('city')

+     * ```

+     * ```

+     * )
+     * ```
+     *
+     * The generated SQL (MySQL):
+     *
+     * ```sql
+     * select `profile`->'$.website.url' as `website_url` from `person`
+     * ```
+     *
+     * Combined with {@link at}:
