> 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.
