> Key: IGNITE-16905
> URL: https://issues.apache.org/jira/browse/IGNITE-16905
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Konstantin Orlov
> Assignee: Pavel Pereslegin

> The problem appears to be caused by an inconsistency of RelReader and RexBuilder: RelReader diserializes every integer value as a value of type Integer, but the RexBuilder assumes that for TIMESTAMP literal a value of type Long will be passed, and make the explicit cast:
> {code:java}
> // RexBuilder#clean(Object, RelDataType)
> case TIMESTAMP:
> if (o instanceof TimestampString) {
> return o;
> } else if (o instanceof Calendar) {
> if (!((Calendar) o).getTimeZone().equals(DateTimeUtils.UTC_ZONE)) {
> throw new AssertionError();
> }
> return TimestampString.fromCalendarFields((Calendar) o);
> } else {
> return TimestampString.fromMillisSinceEpoch((Long) o);
> } {code}
>
> Here is a stack trace:
> {noformat}
> Caused by: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.Long (java.lang.Integer and java.lang.Long are in module java.base of loader 'bootstrap')
