            Reporter: jibiyr


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 title|https://issues.apache.org/jira/browse/FLINK-19670?focusedCommentId=17297877&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17297877]
