{noformat}
however, the calcite std array constructor and spark array, it shows like below:
{noformat}
0: jdbc:calcite:model=src/test/resources/mode> select array[row(1,2), null];
+----------------+
| EXPR$0 |
+----------------+
| [{1, 2}, null] |
+----------------+
{noformat}
{noformat}
spark-sql (default)> select array((1,2), null);
[{"col1":1,"col2":2},null]
{noformat}
They supported row and null literal to coexist(the generated component type is
nullable row/struct).
The reason is because of current SameOperandTypeChecker of spark array will
call *SqlTypeUtil.isComparable* like below:
{noformat}
if (type1.isStruct() != type2.isStruct()) {return false;}
{noformat}
It will reject row(struct) type and NULL, then throw exception. It seems we
should write a more general OperandTypeChecker
was:
when we run
{noformat}
array(row(1,2), null)
{noformat}
It will give 'Parameters must be of the same type' exception.
{noformat}
