Spark : Giving NULL result
0: jdbc:hive2://10.18.19.208:23040/default> select * from emp12;
+-----+---------+
| id | name |
+-----+---------+
| 20 | test |
| 10 | number |
+-----+---------+
2 rows selected (3.683 seconds)
0: jdbc:hive2://10.18.19.208:23040/default> select id as ID, id+name as address from emp12;
+-----+----------+
| ID | address |
+-----+----------+
| 20 | NULL |
| 10 | NULL |
+-----+----------+
2 rows selected (0.649 seconds)
0: jdbc:hive2://10.18.19.208:23040/default> select id as ID, id+name as address from emp12;
+-----+----------+
| ID | address |
+-----+----------+
| 20 | NULL |
| 10 | NULL |
+-----+----------+

0: jdbc:hive2://10.18.19.208:23040/default> select id as ID, id+','+name as address from emp12;
+-----+----------+
| ID | address |
+-----+----------+
| 20 | NULL |
| 10 | NULL |
+-----+----------+
PostgreSQL: Saying throwing Error saying not supported
create table emp12(id int,name varchar(255));
insert into emp12 values(10,'number');
insert into emp12 values(20,'test');
select id as ID, id+','+name as address from emp12;
output: invalid input syntax for integer: ","
create table emp12(id int,name varchar(255));
insert into emp12 values(10,'number');
insert into emp12 values(20,'test');
select id as ID, id+name as address from emp12;
Output: 42883: operator does not exist: integer + character varying
It should throw Error in Spark if it is not supported.
