             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 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}
