The operators limit
and skip
are used for pagination.
limit
specifies the number of rows to retain from the result set and skip
determines the number of objects to skip (i.e. the offset of the result)
The following are examples of different pagination scenarios:
Example: Fetch the first 5 trainers from the list of all trainers:
query {
trainers(
limit: 5
) @mongo {
_id
name
}
}
const { status, data } = await db.get("trainers")
.limit(5)
.apply()
By default, if you don’t specify a limit
clause in your query, Space Cloud enforces a limit of 1000
rows.
This default limit value can be configured easily in the database config. Head over to the Settings
tab in the Database
section of the Mission Control and scroll to the Default limit clause
section. Change the value for the default limit and hit Save
.
Example: Fetch 5 trainers from the list of all trainers starting from the 6th one:
query {
trainers(
skip: 5,
limit: 5
) @mongo {
_id
name
}
}
const { status, data } = await db.get("trainers")
.skip(5)
.limit(5)
.apply()
Example: Fetch first 3 trainers and 2 pokemons of each trainer starting from the 6th one:
query {
trainers(
limit: 3
) @mongo {
_id
name
pokemons(
skip: 5,
limit: 2
) @mongo {
name
}
}
}
