-----------------------------------
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)}}.
