Methods

addAllFrom(Iterable<? extends StructuredQuery.CollectionSelector> values)

public StructuredQuery.Builder addAllFrom(Iterable<? extends StructuredQuery.CollectionSelector> values)

The collections to query.

Parameter
Name Description
values Iterable<? extends com.google.firestore.v1.StructuredQuery.CollectionSelector>
Returns
Type Description
StructuredQuery.Builder

addAllOrderBy(Iterable<? extends StructuredQuery.Order> values)

public StructuredQuery.Builder addAllOrderBy(Iterable<? extends StructuredQuery.Order> values)

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 ASC

  • ORDER BY a DESC becomes ORDER BY a DESC, name DESC
  • WHERE a > 1 becomes WHERE a > 1 ORDER BY a ASC, name ASC
  • WHERE name > ... AND a > 1 becomes WHERE name > ... AND a > 1 ORDER BY a ASC, name ASC

clearSelect()

public StructuredQuery.Builder clearSelect()

Optional sub-set of the fields to return.

Returns
Type Description
StructuredQuery.Builder

clearStartAt()

public StructuredQuery.Builder clearStartAt()

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.

    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.

    setSelect(StructuredQuery.Projection.Builder builderForValue)

    public StructuredQuery.Builder setSelect(StructuredQuery.Projection.Builder builderForValue)

    Optional sub-set of the fields to return.

    This acts as a DocumentMask over the documents returned from a query. When not set, assumes that the caller wants all fields returned.

    .google.firestore.v1.StructuredQuery.Projection select = 1;

    builderForValue StructuredQuery.Projection.Builder
    Returns

    setStartAt(Cursor value)

    public StructuredQuery.Builder setStartAt(Cursor value)

    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;
