> The method {{projectNonColumnEquiConditions}} in HiveCalciteUtil will assign
> the type wrongly for newly created conditions. The problem is in this block:
> {noformat}
> RexNode cond = rexBuilder.makeCall(SqlStdOperatorTable.EQUALS,
> rexBuilder.makeInputRef(newLeftFields.get(i).getType(),
> newLeftOffset + i),
> rexBuilder.makeInputRef(newLeftFields.get(i).getType(),
> newRightOffset + i));
> {noformat}
> It looks like a code copy-paste mistake. In addition, index {{i}} is
> incorrect, as newLeftFields contains all the fields, not only the ones of the
> new condition.
