[−][src]Struct google_datastore1::Query
A query for entities.
This type is not used in any activity, and only used as part of another schema.
Fields
start_cursor: Option<String>
A starting point for the query results. Query cursors are returned in query result batches and can only be used to continue the same query.
kind: Option<Vec<KindExpression>>
The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified.
projection: Option<Vec<Projection>>
The projection to return. Defaults to returning all properties.
distinct_on: Option<Vec<PropertyReference>>
The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned).
filter: Option<Filter>
The filter to apply.
limit: Option<i32>
The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.
offset: Option<i32>
The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.
end_cursor: Option<String>
An ending point for the query results. Query cursors are returned in query result batches and can only be used to limit the same query.
order: Option<Vec<PropertyOrder>>
The order to apply to the query results (if empty, order is unspecified).
