Example 1 with Insert

use of com.facebook.presto.sql.tree.Insert in project presto by prestodb.

the class LogicalPlanner method createInsertPlan.

private RelationPlan createInsertPlan(Analysis analysis, Insert insertStatement) {
    Analysis.Insert insert = analysis.getInsert().get();
    TableMetadata tableMetadata = metadata.getTableMetadata(session, insert.getTarget());
    List<ColumnMetadata> visibleTableColumns = tableMetadata.getColumns().stream().filter(column -> !column.isHidden()).collect(toImmutableList());
    List<String> visibleTableColumnNames = visibleTableColumns.stream().map(ColumnMetadata::getName).collect(toImmutableList());
    RelationPlan plan = createRelationPlan(analysis, insertStatement.getQuery());
    Map<String, ColumnHandle> columns = metadata.getColumnHandles(session, insert.getTarget());
    Assignments.Builder assignments = Assignments.builder();
    for (ColumnMetadata column : tableMetadata.getColumns()) {
        if (column.isHidden()) {
            continue;
        }
        Symbol output = symbolAllocator.newSymbol(column.getName(), column.getType());
        int index = insert.getColumns().indexOf(columns.get(column.getName()));
        if (index < 0) {
            assignments.put(output, new NullLiteral());
        } else {
            Symbol input = plan.getSymbol(index);
            Type tableType = column.getType();
            Type queryType = symbolAllocator.getTypes().get(input);
            if (queryType.equals(tableType) || metadata.getTypeManager().isTypeOnlyCoercion(queryType, tableType)) {
                assignments.put(output, input.toSymbolReference());

                Expression cast = new Cast(input.toSymbolReference(), tableType.getTypeSignature().toString());
                assignments.put(output, cast);
            }
        }
    }
    ProjectNode projectNode = new ProjectNode(idAllocator.getNextId(), plan.getRoot(), assignments.build());
    List<Field> fields = visibleTableColumns.stream().map(column -> Field.newUnqualified(column.getName(), column.getType())).collect(toImmutableList());
    Scope scope = Scope.builder().withRelationType(new RelationType(fields)).build();

Example 2 with Insert

use of com.facebook.presto.sql.tree.Insert in project presto by prestodb.

    Query query = simpleQuery(selectList(new AllColumns()), table(QualifiedName.of("t")));
    assertStatement("INSERT INTO a SELECT * FROM t", new Insert(table, Optional.empty(), query));
    assertStatement("INSERT INTO a (c1, c2) SELECT * FROM t", new Insert(table, Optional.of(ImmutableList.of("c1", "c2")), query));
