Example 1 with Mapping

use of com.hazelcast.sql.impl.schema.Mapping in project hazelcast by hazelcast.

the class MappingColumnsTable method rows.

    for (Mapping mapping : mappings) {
        List<MappingField> fields = mapping.fields();
        for (int i = 0; i < fields.size(); i++) {
            MappingField field = fields.get(i);
            Object[] row = new Object[] { catalog(), schema, mapping.name(), field.name(), field.externalName(), i + 1, String.valueOf(true), field.type().getTypeFamily().name() };
            rows.add(row);
        }
    }
    for (View view : views) {
        for (int i = 0; i < view.viewColumnNames().size(); i++) {
            Object[] row = new Object[] { catalog(), schema, view.name(), view.viewColumnNames().get(i), null, i + 1, String.valueOf(true), view.viewColumnTypes().get(i).getTypeFamily().name() };
            rows.add(row);
        }
    }
    return rows;
}

Example 2 with Mapping

use of com.hazelcast.sql.impl.schema.Mapping in project hazelcast by hazelcast.

the class TableResolverImpl method createMapping.

// region mapping
public void createMapping(Mapping mapping, boolean replace, boolean ifNotExists) {
    Mapping resolved = resolveMapping(mapping);
    String name = resolved.name();
    if (ifNotExists) {
        tableStorage.putIfAbsent(name, resolved);
    } else if (replace) {
        tableStorage.put(name, resolved);
        listeners.forEach(TableListener::onTableChanged);

    Collection<View> views = objects.stream().filter(o -> o instanceof View).map(v -> (View) v).collect(Collectors.toList());
    tables.add(new TablesTable(CATALOG, SCHEMA_NAME_INFORMATION_SCHEMA, SCHEMA_NAME_PUBLIC, mappings, views));
    tables.add(new MappingsTable(CATALOG, SCHEMA_NAME_INFORMATION_SCHEMA, SCHEMA_NAME_PUBLIC, mappings));
