JavaScript: Fetch data

Perform a SELECT query on the table or view.

• By default, Supabase projects return a maximum of 1,000 rows. This setting can be changed in your project's API settings. It's recommended that you keep it low to limit the payload size of accidental or malicious requests. You can use range() queries to paginate through your data.
• select() can be combined with Filters
• select() can be combined with Modifiers
• apikey is a reserved keyword if you're using the Supabase Platform and should be avoided as a column name.

Parameters

• columns

  (Optional)

  The columns to retrieve, separated by commas. Columns can be renamed when returned with `customName:columnName`

• options

  (Required)

  Named parameters

Examples

Getting your data

const \{ data, error \} = await supabase
  .from('countries')
  .select()

Selecting specific columns

const \{ data, error \} = await supabase
  .from('countries')
  .select('name')

Query referenced tables

const \{ data, error \} = await supabase
  .from('countries')
  .select(`
    name,
    cities (
      name
    )
  `)

Query referenced tables through a join table

const \{ data, error \} = await supabase
  .from('users')
  .select(`
    name,
    teams (
      name
    )
  `)

Query the same referenced table multiple times

const \{ data, error \} = await supabase
  .from('messages')
  .select(`
    content,
    from:sender_id(name),
    to:receiver_id(name)
  `)

// To infer types, use the name of the table (in this case `users`) and
// the name of the foreign key constraint.
const \{ data, error \} = await supabase
  .from('messages')
  .select(`
    content,
    from:users!messages_sender_id_fkey(name),
    to:users!messages_receiver_id_fkey(name)
  `)

Filtering through referenced tables

const \{ data, error \} = await supabase
  .from('cities')
  .select('name, countries(*)')
  .eq('countries.name', 'Estonia')

Querying referenced table with count

const \{ data, error \} = await supabase
  .from('countries')
  .select(`*, cities(count)`)

Querying with count option

const \{ count, error \} = await supabase
  .from('countries')
  .select('*', \{ count: 'exact', head: true \})

Querying JSON data

const \{ data, error \} = await supabase
  .from('users')
  .select(`
    id, name,
    address->city
  `)

Querying referenced table with inner join

const \{ data, error \} = await supabase
  .from('cities')
  .select('name, countries!inner(name)')
  .eq('countries.name', 'Indonesia')

Switching schemas per query

const \{ data, error \} = await supabase
  .schema('myschema')
  .from('mytable')
  .select()
