/**
|
||||
* Creates a `select` query builder for the given table or tables.
|
||||
*
|
||||
* The tables passed to this method are built as the query's `from` clause.
|
||||
*
|
||||
* ### Examples
|
||||
*
|
||||
* Create a select query for one table:
|
||||
*
|
||||
* ```ts
|
||||
* db.selectFrom('person').selectAll()
|
||||
* ```
|
||||
*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|
||||
* ```sql
|
||||
* select * from "person"
|
||||
* ```
|
||||
*
|
||||
* Create a select query for one table with an alias:
|
||||
*
|
||||
* ```ts
|
||||
* const persons = await db.selectFrom('person as p')
|
||||
* .select(['p.id', 'first_name'])
|
||||
* .execute()
|
||||
*
|
||||
* console.log(persons[0].id)
|
||||
* ```
|
||||
*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|
||||
* ```sql
|
||||
* select "p"."id", "first_name" from "person" as "p"
|
||||
* ```
|
||||
*
|
||||
* Create a select query from a subquery:
|
||||
*
|
||||
* ```ts
|
||||
* const persons = await db.selectFrom(
|
||||
* (eb) => eb.selectFrom('person').select('person.id as identifier').as('p')
|
||||
* )
|
||||
* .select('p.identifier')
|
||||
* .execute()
|
||||
*
|
||||
* console.log(persons[0].identifier)
|
||||
* ```
|
||||
*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|
||||
* ```sql
|
||||
* select "p"."identifier",
|
||||
* from (
|
||||
* select "person"."id" as "identifier" from "person"
|
||||
* ) as p
|
||||
* ```
|
||||
*
|
||||
* Create a select query from raw sql:
|
||||
*
|
||||
* ```ts
|
||||
* import { sql } from 'kysely'
|
||||
*
|
||||
* const items = await db
|
||||
* .selectFrom(sql<{ one: number }>`(select 1 as one)`.as('q'))
|
||||
* .select('q.one')
|
||||
* .execute()
|
||||
*
|
||||
* console.log(items[0].one)
|
||||
* ```
|
||||
*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|
||||
* ```sql
|
||||
* select "q"."one",
|
||||
* from (
|
||||
* select 1 as one
|
||||
* ) as q
|
||||
* ```
|
||||
*
|
||||
* When you use the `sql` tag you need to also provide the result type of the
|
||||
* raw snippet / query so that Kysely can figure out what columns are
|
||||
* available for the rest of the query.
|
||||
*
|
||||
* The `selectFrom` method also accepts an array for multiple tables. All
|
||||
* the above examples can also be used in an array.
|
||||
*
|
||||
* ```ts
|
||||
* import { sql } from 'kysely'
|
||||
*
|
||||
* const items = await db.selectFrom([
|
||||
* 'person as p',
|
||||
* db.selectFrom('pet').select('pet.species').as('a'),
|
||||
* sql<{ one: number }>`(select 1 as one)`.as('q')
|
||||
* ])
|
||||
* .select(['p.id', 'a.species', 'q.one'])
|
||||
* .execute()
|
||||
* ```
|
||||
*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|
||||
* ```sql
|
||||
* select "p".id, "a"."species", "q"."one"
|
||||
* from
|
||||
* "person" as "p",
|
||||
* (select "pet"."species" from "pet") as a,
|
||||
* (select 1 as one) as "q"
|
||||
* ```

* ### Examples
|
||||
*
|
||||
* <!-- siteExample("cte", "Simple selects", 10) -->
|
||||
*
|
||||
* Common table expressions (CTE) are a great way to modularize complex queries.
|
||||
* Essentially they allow you to run multiple separate queries within a
|
||||
* single roundtrip to the DB.
|
||||
*
|
||||
* Since CTEs are a part of the main query, query optimizers inside DB
|
||||
* engines are able to optimize the overall query. For example, postgres
|
||||
* is able to inline the CTEs inside the using queries if it decides it's
|
||||
* faster.
|
||||
*
|
||||
* ```ts
|
||||
* const result = await db
|
||||
* // Create a CTE called `jennifers` that selects all
|
||||
* // persons named 'Jennifer'.
|
||||
* .with('jennifers', (db) => db
|
||||
* .selectFrom('person')
|
||||
* .where('first_name', '=', 'Jennifer')
|
||||
* .select(['id', 'age'])
|
||||
* )
|
||||
* // Select all rows from the `jennifers` CTE and
|
||||
* // further filter it.
|
||||
* .with('adult_jennifers', (db) => db
|
||||
* .selectFrom('jennifers')
|
||||
* .where('age', '>', 18)
|
||||
* .select(['id', 'age'])
|
||||
* )
|
||||
* // Finally select all adult jennifers that are
|
||||
* // also younger than 60.
|
||||
* .selectFrom('adult_jennifers')
|
||||
* .where('age', '<', 60)
|
||||
* .selectAll()
|
||||
* .execute()
|
||||
* ```
|
||||
*
|
||||
* <!-- siteExample("cte", "Inserts, updates and deletions", 20) -->
|
||||
*
|
||||
* Some databases like postgres also allow you to run other queries than selects
|
||||
* in CTEs. On these databases CTEs are extremely powerful:
|
||||
*
|
||||
* ```ts
|
||||
* const result = await db
|
||||
* .with('new_person', (db) => db
|
||||
* .insertInto('person')
|
||||
* .values({
|
||||
* first_name: 'Jennifer',
|
||||
* age: 35,
|
||||
* })
|
||||
* .returning('id')
|
||||
* )
|
||||
* .with('new_pet', (db) => db
|
||||
* .insertInto('pet')
|
||||
* .values({
|
||||
* name: 'Doggo',
|
||||
* species: 'dog',
|
||||
* is_favorite: true,
|

|

* await db
|

* .with('jennifers(id, age)', (db) => db

|
||||
* .where('first_name', '=', 'Jennifer')
|
||||
* // This is ok since we return columns with the same
|
||||
* // names as specified by `jennifers(id, age)`.
|
||||
* .select(['id', 'age'])
|
||||
* )

|

* .selectAll()
|

* .execute()
|

* ```
|
||||
*
|
||||
* The first argument can also be a callback. The callback is passed
|
||||
* a `CTEBuilder` instance that can be used to configure the CTE:
|
||||
*
|
||||
* ```ts
|
||||
* await db

*
|
||||
* The generated SQL (PostgreSQL):
|
||||
*
|

* ```sql
|

* select * from "mammals"."pet"

* inner join "public"."person"

*
|
||||
* `withSchema` is smart enough to not add schema for aliases,
|
||||
* common table expressions or other places where the schema
|
||||
* doesn't belong to:
|

*
|

* ```
