> hi,community. now calcite support SqlSnapshot.
> when a sql like _*SELECT orders.order_id, products.pro_id,
> products.product_name*_
> _*FROM default_catalog.default_database.orders AS orders*_
> _*LEFT JOIN default_catalog.default_database.products FOR SYSTEM_TIME AS OF
> orders.proctime AS products ON orders.product_id = products.pro_id .*_
>
> _*default_catalog.default_database.products FOR SYSTEM_TIME AS OF
> orders.proctime AS products*_ parse to SqlSnapshot .however, when unparse.
> it is _*default_catalog.default_database.products AS products FOR SYSTEM_TIME
> AS OF orders.proctime.*_ which can not be parsed again.
>
> if we should consider this condition.
> the same problem when I found in FLINK-19670.
