And what about

ClickHouse/src/Functions/in.cpp

Lines 125 to 126 in d5fd0c4

	auto set = column_set->getData();
	auto set_types = set->getDataTypes();

ClickHouse/src/Interpreters/ExpressionActions.cpp

Lines 943 to 944 in d5fd0c4

	if (column_set->getData()->isCreated() && column_set->getData()->getTotalRowCount() == 0)
	return true;

do we need to check also there or at any other similar places were getData is used?

[davenger]

Yes.
I've added the checks
