--------------------------------
Summary: union and set operations have wrong exception infomation
Key: SPARK-32131
URL: https://issues.apache.org/jira/browse/SPARK-32131
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.0.0
Reporter: philipse
Union and set operations can only be performed on tables with the compatible
column types,while when we have more than two column, the warning messages will
have wrong column index.Steps to reproduce.
Step1:prepare test data
{code:java}
drop table if exists test1;
drop table if exists test2;
drop table if exists test3;
create table if not exists test1(id int, age int, name timestamp);
create table if not exists test2(id int, age timestamp, name timestamp);
create table if not exists test3(id int, age int, name int);
insert into test1 select 1,2,'2020-01-01 01:01:01';
insert into test2 select 1,'2020-01-01 01:01:01','2020-01-01 01:01:01';
insert into test3 select 1,3,4;
{code}
Step2:do query:
{code:java}
Query1:
select * from test1 except select * from test2;
Result1:
Error: org.apache.spark.sql.AnalysisException: Except can only be performed on
tables with the compatible column types. timestamp <> int at the second column
of the second table;; 'Except false :- Project [id#620, age#621, name#622] : +-
SubqueryAlias `default`.`test1` : +- HiveTableRelation `default`.`test1`,
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#620, age#621, name#622]
+- Project [id#623, age#624, name#625] +- SubqueryAlias `default`.`test2` +-
HiveTableRelation `default`.`test2`,
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#623, age#624, name#625]
(state=,code=0)
Query2:
select * from test1 except select * from test3;
Result2:
Error: org.apache.spark.sql.AnalysisException: Except can only be performed on
tables with the compatible column types. int <> timestamp at the 2th column of
the second table;; 'Except false :- Project [id#632, age#633, name#634] : +-
SubqueryAlias `default`.`test1` : +- HiveTableRelation `default`.`test1`,
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#632, age#633, name#634]
+- Project [id#635, age#636, name#637] +- SubqueryAlias `default`.`test3` +-
HiveTableRelation `default`.`test3`,
org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [id#635, age#636, name#637]
(state=,code=0)
{code}
the result of query1 is correct, while query2 have the wrong errors,it should
be the third column
