             Summary: Fix the casting problem for function TIMESTAMPADD in Table
                 Key: FLINK-10009
                 URL: https://issues.apache.org/jira/browse/FLINK-10009
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
            Reporter: Xingcan Cui


There seems to be a bug in {{TIMESTAMPADD}} function. For example, {{TIMESTAMPADD(MINUTE, 1, DATE '2016-06-15')}} throws a {{ClassCastException}} ( java.lang.Integer cannot be cast to java.lang.Long). Actually, it tries to cast an integer date to a long timestamp in RexBuilder.java:1524 - {{return TimestampString.fromMillisSinceEpoch((Long) o)}}.
