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 [link
