Reference documentation and code samples for the Cloud Firestore V1beta1 Client class StructuredQuery.

A Firestore query.

Generated from protobuf message google.firestore.v1beta1.StructuredQuery

Namespace

Google \ Cloud \ Firestore \ V1beta1

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ select	StructuredQuery\Projection The projection to return.
↳ from	array<StructuredQuery\CollectionSelector> The collections to query.
↳ where	StructuredQuery\Filter The filter to apply.
↳ order_by	array<StructuredQuery\Order> The order to apply to the query results. Firestore guarantees a stable ordering through the following rules: * * Any field required to appear in order_by, that is not already specified in order_by, is appended to the order in field name order by default. * * 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: * * SELECT * FROM Foo ORDER BY A becomes SELECT * FROM Foo ORDER BY A, __name__ * * SELECT * FROM Foo ORDER BY A DESC becomes SELECT * FROM Foo ORDER BY A DESC, __name__ DESC * * SELECT * FROM Foo WHERE A > 1 becomes SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__
↳ start_at	Cursor A starting point for the query results.
↳ end_at	Cursor A end point for the query results.
↳ offset	int The number of results to skip. Applies before limit, but after all other constraints. Must be >= 0 if specified.
↳ limit	Google\Protobuf\Int32Value The maximum number of results to return. Applies after all other constraints. Must be >= 0 if specified.

getSelect

• SELECT * FROM Foo ORDER BY A becomes SELECT * FROM Foo ORDER BY A, __name__
• SELECT * FROM Foo ORDER BY A DESC becomes SELECT * FROM Foo ORDER BY A DESC, __name__ DESC
• SELECT * FROM Foo WHERE A > 1 becomes SELECT * FROM Foo WHERE A > 1 ORDER BY A, __name__
