Examples with Params jakarta.nosql.Params used on opensource projects

Example 1 with Params

use of jakarta.nosql.Params in project jnosql-diana by eclipse.

the class SelectQueryParser method apply.

@Override
public ColumnQueryParams apply(SelectQuery selectQuery, ColumnObserverParser observer) {
    Objects.requireNonNull(selectQuery, "selectQuery is required");
    Objects.requireNonNull(observer, "observer is required");
    Params params = Params.newParams();
    ColumnQuery columnQuery = getColumnQuery(params, selectQuery, observer);
    return new DefaultColumnQueryParams(columnQuery, params);
}

Example 2 with Params

use of jakarta.nosql.Params in project jnosql-diana by eclipse.

the class Values method get.

static Object get(QueryValue<?> value, Params parameters) {
    ValueType type = value.getType();
    switch(type) {
        case NUMBER:
        case STRING:
            return value.get();
        case PARAMETER:
            return parameters.add(ParamQueryValue.class.cast(value).get());
        case ARRAY:
            return Stream.of(ArrayQueryValue.class.cast(value).get()).map(v -> get(v, parameters)).collect(toList());
        case FUNCTION:
            Function function = FunctionQueryValue.class.cast(value).get();
            String name = function.getName();
            Object[] params = function.getParams();
            if ("convert".equals(name)) {
                return jakarta.nosql.Value.of(get(QueryValue.class.cast(params[0]), parameters)).get((Class<?>) params[1]);
            }
            String message = String.format("There is not support to the function: %s with parameters %s", name, Arrays.toString(params));
            throw new QueryException(message);
        case JSON:
            return JsonObjects.getColumns(JSONQueryValue.class.cast(value).get());
        case CONDITION:
        default:
            throw new QueryException("There is not support to the value: " + type);
    }
}

Example 3 with Params

use of jakarta.nosql.Params in project jnosql-diana by eclipse.

the class UpdateQueryParser method prepare.

ColumnPreparedStatement prepare(String query, ColumnFamilyManager manager, ColumnObserverParser observer) {
    Params params = Params.newParams();
    UpdateQuery updateQuery = updateQueryProvider.apply(query);
    ColumnEntity entity = getEntity(params, updateQuery, observer);
    return DefaultColumnPreparedStatement.update(entity, params, query, manager);
}

Example 4 with Params

use of jakarta.nosql.Params in project jnosql-diana by eclipse.

the class DeleteQueryParser method getQuery.

private ColumnDeleteQuery getQuery(Params params, ColumnObserverParser observer, DeleteQuery deleteQuery) {
    String columnFamily = observer.fireEntity(deleteQuery.getEntity());
    List<String> columns = deleteQuery.getFields().stream().map(f -> observer.fireField(columnFamily, f)).collect(Collectors.toList());
    ColumnCondition condition = null;
    if (deleteQuery.getWhere().isPresent()) {
        condition = deleteQuery.getWhere().map(c -> Conditions.getCondition(c, params, observer, columnFamily)).get();
    }
    return new DefaultColumnDeleteQuery(columnFamily, condition, columns);
}

Example 5 with Params

use of jakarta.nosql.Params in project jnosql-diana by eclipse.

the class DeleteQueryParser method getQuery.

private ColumnDeleteQuery getQuery(String query, ColumnObserverParser observer) {
    DeleteQuery deleteQuery = deleteQueryProvider.apply(query);
    String columnFamily = observer.fireEntity(deleteQuery.getEntity());
    List<String> columns = deleteQuery.getFields().stream().map(f -> observer.fireField(columnFamily, f)).collect(Collectors.toList());
    ColumnCondition condition = null;
    Params params = Params.newParams();
    if (deleteQuery.getWhere().isPresent()) {
        condition = deleteQuery.getWhere().map(c -> Conditions.getCondition(c, params, observer, columnFamily)).get();
    }
    if (params.isNotEmpty()) {
        throw new QueryException("To run a query with a parameter use a PrepareStatement instead.");
    }
    return new DefaultColumnDeleteQuery(columnFamily, condition, columns);
