SUMMARY
The following query cannot be parsed by
sqlparse
, even though it's valid:This happens because
sqlparse
treatsrows
as a reserved word, even though the query is valid in Presto.Our users have been overcoming the problem by quoting
rows
. This preventssqlparse
from treating it as a reserved word. But it's confusing to users, because the underlying engine (Presto) doesn't require it.Instead, I fixed it by following Postel's Law, and being liberal about user input.
TEST PLAN
I added a unit test that covers the bug, and another basic one.
