getResultRow
The getResultRow
method returns an object containing the entire data of a single ResultRow
in the ResultTable
of the given query.
getResultRow(
queryId: string,
rowId: string,
): ResultRow
Type | Description | |
---|---|---|
queryId | string | The |
rowId | string | The |
returns | ResultRow | An object containing the entire data of the |
This has the same behavior as a Store
's getRow
method. For example, if the query or ResultRow
Id
is invalid, the method returns an empty object. Similarly, it returns a copy of, rather than a reference to the underlying data, so changes made to the returned object are not made to the query results themselves.
Example
This example creates a Queries
object, a single query definition, and then calls this method on it (as well as a non-existent ResultRow
Id
) to get the ResultRow
.
import {createQueries, createStore} from 'tinybase';
const store = createStore().setTable('pets', {
fido: {species: 'dog', color: 'brown'},
felix: {species: 'cat', color: 'black'},
cujo: {species: 'dog', color: 'black'},
});
const queries = createQueries(store).setQueryDefinition(
'dogColors',
'pets',
({select, where}) => {
select('color');
where('species', 'dog');
},
);
console.log(queries.getResultRow('dogColors', 'fido'));
// -> {color: 'brown'}
console.log(queries.getResultRow('dogColors', 'felix'));
// -> {}
