Example 1 with ValidityDateNode

use of com.bakdata.conquery.models.query.queryplan.specific.ValidityDateNode in project conquery by bakdata.

the class CQConcept method createQueryPlan.

        final List<Aggregator<?>> connectorAggregators = createAggregators(plan, table.getSelects());

        // They also don't need aggregation as they simply imitate their reference.
        List<ExistsAggregator> existsAggregators = connectorAggregators.stream().filter(ExistsAggregator.class::isInstance).map(ExistsAggregator.class::cast).collect(Collectors.toList());

        final boolean hasSelectedSecondaryId = Arrays.stream(table.getConnector().getTable().getColumns()).map(Column::getSecondaryId).filter(Objects::nonNull).anyMatch(o -> Objects.equals(context.getSelectedSecondaryId(), o));
        final Column validityDateColumn = selectValidityDateColumn(table);
        final ConceptNode node = new ConceptNode(// TODO Don't set validity node, when no validity column exists. See workaround for this and remove it: https://github.com/bakdata/conquery/pull/1362
        new ValidityDateNode(validityDateColumn, filtersNode), elements, table, // if the node is excluded, don't pass it into the Node.
        !excludeFromSecondaryId && hasSelectedSecondaryId ? context.getSelectedSecondaryId() : null);
        tableNodes.add(node);

    // We always merge on concept level
    final QPNode outNode = OrNode.of(tableNodes, aggregateEventDates ? DateAggregationAction.MERGE : DateAggregationAction.BLOCK);
    // Link concept-level Exists-select to outer node.
    conceptAggregators.stream().filter(aggregator -> aggregator instanceof ExistsAggregator).forEach(aggregator -> ((ExistsAggregator) aggregator).setReference(outNode));
    return outNode;
}

Example 2 with ValidityDateNode

use of com.bakdata.conquery.models.query.queryplan.specific.ValidityDateNode in project conquery by bakdata.

the class CQDateRestriction method createQueryPlan.

@Override
public QPNode createQueryPlan(QueryPlanContext context, ConceptQueryPlan plan) {
    QPNode childAgg = child.createQueryPlan(context.withDateRestriction(CDateRange.of(dateRange)), plan);
    // insert behind every ValidityDateNode
    Queue<QPNode> openList = new ArrayDeque<>();
    openList.add(childAgg);
    while (!openList.isEmpty()) {
        QPNode current = openList.poll();
        if (current instanceof ValidityDateNode) {
            ValidityDateNode validityDateNode = (ValidityDateNode) current;
            validityDateNode.setChild(new DateRestrictingNode(CDateSet.create(Collections.singleton(CDateRange.of(dateRange))), validityDateNode.getChild()));
        } else if (current instanceof NegatingNode) {
        // we can't push date restrictions past negations
        } else {
            openList.addAll(current.getChildren());
