[jira] [Commented] (CALCITE-5691) Planning error with subquery inside IN
[ https://issues.apache.org/jira/browse/CALCITE-5691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17719963#comment-17719963 ]
Soumyava Das commented on CALCITE-5691:
---------------------------------------
I have observed that in `RelOptPredicateList.java` this part of the code is creating the IndexOutOfBoundsException
{code:java}
if (SqlKind.COMPARISON.contains(e.getKind())) {
// A comparison with a (non-null) literal, such as 'ref < 10', is not null if 'ref'
// is not null.
RexCall call = (RexCall) e;
if (call.getOperands().get(1) instanceof RexLiteral
&& !((RexLiteral) call.getOperands().get(1)).isNull()) {
return isEffectivelyNotNull(call.getOperands().get(0));
}
} {code}

> I tried a query which is similar to the one I use in the sqlline component and I see the query still to fail. The query is
