SELECT parser can fail to parse subselects or multistatement SELECTs
--------------------------------------------------------------------
Key: SEQUOIA-846
URL: https://forge.continuent.org/jira/browse/SEQUOIA-846
Project: Sequoia
Type: Bug
Components: Core
Versions: Sequoia 3.0 beta1, Sequoia 2.10.2
Reporter: Emmanuel Cecchet
Assigned to: Emmanuel Cecchet
Fix For: Sequoia 2.10.3, Sequoia 3.0
SELECT request parser tries to look for subselects to extract all table names.
If subselect parsing fails, the fallback mechanism in the catch block returns
an unaliased list of tables which will cause a ClassCastException later on.
Note that in Sequoia 3.0, the SemanticManager is not set on the subselect
request which will cause subselect parsing to systematically fail.
Additionally the Sequoia SQL console tries to send multistatement SELECTs
through executeQuery (which is not correct) but cause the parser to fail (try
statement.executeQuery("SELECT * from foo ; SELECT * FROM foo").
