------------------------------------
Summary: Parser allows MERGE with mismatched parentheses
Key: CALCITE-5206
URL: https://issues.apache.org/jira/browse/CALCITE-5206
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
The SQL parser allows invalid MERGE statements with mismatched parentheses. For
example, the following invalid statement is treated as valid but is missing a
trailing ')':
{code}
merge into emps as e
using temps as t on e.empno = t.empno
when not matched
then insert (a, b) (values (1, 2);
{code}
And the following invalid statement is treated as valid but has an unmatched

{code}
