説明
CREATE STABLE IF NOT EXISTS point_data (
time timestamp,
val BINARY(64)
) TAGS (point_id bigint);
CREATE STREAM stream1
INTO point_data subtable('p10')
as
SELECT p1.time, p1.val+p2.val
FROM p1, p2 WHERE p1.time=p2.time;
例如这样，想要实时计算两个子表的和，存在另一个子表里，tdengine支持吗？ 应该怎么写？ 现在的写法报错：DB error: Unsupported stream query
