Indexes

Indexes( [database] )

Indexes( [database] )

indexes( [database] )
Indexes( [database] )

Description

The Indexes function, when executed with Paginate, returns an array of References for all indexes in the specified child database. If a child database is not specified, the returned index references all belong to the current database.

When a child database is specified, an admin key must be used to call Indexes (server or client keys, or ABAC tokens, cannot be used to access a child database).

Parameters

Argument Type Definition and Requirements

database

Reference

Optional - A reference to a child database. If not specified, the current database is used.

Returns

A Set reference for the available indexes in the specified child database (or the current database if database is not specified).

Examples

The following query gets the references to all indexes in the current database:

client.Query(
    Paginate(Indexes())
);
ObjectV(data: Arr(RefV(id = "spells_by_element", collection = RefV(id = "indexes")), RefV(id = "spellbooks_by_owner", collection = RefV(id = "indexes")), RefV(id = "spells_by_spellbook", collection = RefV(id = "indexes")), RefV(id = "spells_by_element_and_name", collection = RefV(id = "indexes")), RefV(id = "elements_of_spells", collection = RefV(id = "indexes")), RefV(id = "letters", collection = RefV(id = "indexes")), RefV(id = "people_by_age_first", collection = RefV(id = "indexes")), RefV(id = "people_by_last_first", collection = RefV(id = "indexes")), RefV(id = "users_by_email", collection = RefV(id = "indexes"))))
result, err := client.Query(
	f.Paginate(f.Indexes()))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[data:[{spells_by_element 0xc00008e240 0xc00008e240 <nil>} {spellbooks_by_owner 0xc00008e330 0xc00008e330 <nil>} {spells_by_spellbook 0xc00008e420 0xc00008e420 <nil>} {spells_by_element_and_name 0xc00008e510 0xc00008e510 <nil>} {elements_of_spells 0xc00008e600 0xc00008e600 <nil>} {letters 0xc00008e6f0 0xc00008e6f0 <nil>} {people_by_age_first 0xc0000bf1d0 0xc0000bf1d0 <nil>} {people_by_last_first 0xc0000bf2c0 0xc0000bf2c0 <nil>} {users_by_email 0xc0000bf3b0 0xc0000bf3b0 <nil>}]]
System.out.println(
    client.query(
        Paginate(Indexes())
    ).get());
{data: [ref(id = "spells_by_element", collection = ref(id = "indexes")), ref(id = "spellbooks_by_owner", collection = ref(id = "indexes")), ref(id = "spells_by_spellbook", collection = ref(id = "indexes")), ref(id = "spells_by_element_and_name", collection = ref(id = "indexes")), ref(id = "elements_of_spells", collection = ref(id = "indexes")), ref(id = "letters", collection = ref(id = "indexes")), ref(id = "people_by_age_first", collection = ref(id = "indexes")), ref(id = "people_by_last_first", collection = ref(id = "indexes")), ref(id = "users_by_email", collection = ref(id = "indexes"))]}
client.query(
  q.Paginate(q.Indexes())
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))
{
  data: [
    Index("spells_by_element"),
    Index("spellbooks_by_owner"),
    Index("spells_by_spellbook"),
    Index("spells_by_element_and_name"),
    Index("elements_of_spells"),
    Index("letters"),
    Index("people_by_age_first"),
    Index("people_by_last_first"),
    Index("users_by_email")
  ]
}
result = client.query(
  q.paginate(q.indexes())
)
print(result)
{'data': [Ref(id=spells_by_element, collection=Ref(id=indexes)), Ref(id=spellbooks_by_owner, collection=Ref(id=indexes)), Ref(id=spells_by_spellbook, collection=Ref(id=indexes)), Ref(id=spells_by_element_and_name, collection=Ref(id=indexes)), Ref(id=elements_of_spells, collection=Ref(id=indexes)), Ref(id=letters, collection=Ref(id=indexes)), Ref(id=people_by_age_first, collection=Ref(id=indexes)), Ref(id=people_by_last_first, collection=Ref(id=indexes)), Ref(id=users_by_email, collection=Ref(id=indexes))]}
client.query(Paginate(Indexes()))
{data: [ref(id = "spells_by_element", collection = ref(id = "indexes")), ref(id = "spellbooks_by_owner", collection = ref(id = "indexes")), ref(id = "spells_by_spellbook", collection = ref(id = "indexes")), ref(id = "spells_by_element_and_name", collection = ref(id = "indexes")), ref(id = "elements_of_spells", collection = ref(id = "indexes")), ref(id = "letters", collection = ref(id = "indexes")), ref(id = "people_by_age_first", collection = ref(id = "indexes")), ref(id = "people_by_last_first", collection = ref(id = "indexes")), ref(id = "users_by_email", collection = ref(id = "indexes"))]}

The following query demonstrates what happens when no indexes exist:

Value result = await client.Query(
    Paginate(Indexes())
);
ObjectV(data: Arr())
result, err := client.Query(
	f.Paginate(f.Indexes()))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[data:[]]
System.out.println(
    client.query(
        Paginate(Indexes())
    ).get());
{data: []}
client.query(
  q.Paginate(q.Indexes())
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))
{ data: [] }
result = client.query(
  q.paginate(q.indexes())
)
print(result)
{'data': []}
println(Await.result(
  client.query(
    Paginate(Indexes())
  ),
  5.seconds
))
{data: []}
