getOrderBy(int index)
public StructuredQuery.Order getOrderBy(int index)
The order to apply to the query results.
Firestore allows callers to provide a full ordering, a partial ordering, or
no ordering at all. In all cases, Firestore guarantees a stable ordering
through the following rules:
- The
order_by is required to reference all fields used with an
inequality filter.
- All fields that are required to be in the
order_by but are not already
present are appended in lexicographical ordering of the field name.
- If an order on
name is not specified, it is appended by default.
Fields are appended with the same sort direction as the last order
specified, or 'ASCENDING' if no order was specified. For example:
ORDER BY a becomes ORDER BY a ASC, name ASCORDER BY a DESC becomes ORDER BY a DESC, name DESCWHERE a > 1 becomes WHERE a > 1 ORDER BY a ASC, name ASCWHERE name > ... AND a > 1 becomes
WHERE name > ... AND a > 1 ORDER BY a ASC, name ASC

getStartAt()
public Cursor getStartAt()
A potential prefix of a position in the result set to start the query at.
The ordering of the result set is based on the ORDER BY clause of the
original query.
`
SELECT * FROM k WHERE a = 1 AND b > 2 ORDER BY b ASC, name ASC;
This query's results are ordered by (b ASC, name ASC).
Cursors can reference either the full ordering or a prefix of the location,
though it cannot reference more fields than what are in the provided
ORDER BY.
Continuing off the example above, attaching the following start cursors
will have varying impact:
START BEFORE (2, /k/123)
: start the query right before a = 1 AND
b > 2 AND
name > /k/123
.
START AFTER (10)
: start the query right after a = 1 AND b > 10
.
Unlike OFFSET
which requires scanning over the first N results to skip,
a start cursor allows the query to begin at a logical position. This
position is not required to match an actual result, it will scan forward
from this position to find the next document.
Requires:
The number of values cannot be greater than the number of fields
specified in the ORDER BY` clause.
.google.firestore.v1.Cursor start_at = 7;
| Returns |
|---|
| Type | Description |
Cursor | The startAt.
