…able_compression
The Oracle ANTLR grammar's table_compression rule was missing support for
Oracle 12c+ ROW STORE and COLUMN STORE compression syntax, causing
"Syntax error ... ROW STORE" when parsing valid CREATE TABLE DDL.
Add ROW STORE COMPRESS [BASIC | ADVANCED] and
COLUMN STORE COMPRESS [FOR {QUERY | ARCHIVE} [LOW | HIGH]] [[NO] ROW LEVEL LOCKING]
as alternatives in the table_compression rule.
