Support map_entries function #1916
Description
Describe the bug
The test has a query -
sql(
"select optional_array[0], " +
"array_of_struct[0].field1, " +
"array_of_struct[0].optional_nested_array, " +
"optional_map.key, " +
"optional_map.value, " +
"map_keys(complex_map), " +
"map_values(complex_map) " +
"from complex_types")
which could be
sql(
"select optional_array[0], " +
"array_of_struct[0].field1, " +
"array_of_struct[0].optional_nested_array, " +
"optional_map.key, " +
"optional_map.value, " +
"map_entries(complex_map), " +
"map_keys(complex_map), " +
"map_values(complex_map) " +
"from complex_types")
to ensure map_entries are also read correctly.
