@viirya Hi Simon, many thanks for finding this. Instead of adding the
compensation code in the resolve logic for in-subquery expression can we
consider to move the semantic checking of comparing the count of arguments in
either side of in-subquery expression to checkAnalysis instead ? We do several
other checks in checkAnalysis for subquery expression. I just feel this may be
a little cleaner ?
For your reference, i quickly tried it
