Thomas Rebele commented on CALCITE-5686:
----------------------------------------
Sorry, I've used a workaround, which was better suited to the problem at the
end. I hope I'll find some time soon to work on the remaining Calcite tickets
that are assigned to me.

> Key: CALCITE-5686
> URL: https://issues.apache.org/jira/browse/CALCITE-5686
> Project: Calcite
> Issue Type: Improvement
> Reporter: Thomas Rebele
> Assignee: Thomas Rebele
> Priority: Minor
>
> The following block in org.apache.calcite.linq4j.tree.Shuttle prevents
> replacing constants with other expressions:
> {code:java}
> public ConstantExpression visit(ConstantExpression constantExpression) {
> return constantExpression;
> } {code}
> The return type of the corresponding accept function is more general:
> {code:java}
> @Override public Expression accept(Shuttle shuttle) {
> return shuttle.visit(this);
> } {code}
