Hi all,
Currently I see tablesample substitute('medium') in calcite's parser.jj
file and some single tests, but I looked at the tablesample documentation
for Postgresql and some other databases, Not seeing this SQL syntax, I was
wondering what exactly tablesample substitute('medium') means?
At the same time,consider the following SQL:
select * from product TABLESAMPLE SUBSTITUTE('medium') After the SqlNode to
RelNode, it also loses the TABLESAMPLE SUBSTITUTE('medium') information.
Best, LakeShen
