Xiao Meng created DRILL-1029:
--------------------------------
Summary: select column from a `select *` sub-query fails for
schema-less file
Key: DRILL-1029
URL: https://issues.apache.org/jira/browse/DRILL-1029
Project: Apache Drill
Issue Type: Bug
Reporter: Xiao Meng
Priority: Critical
The following query is generated by Tableau to import data from custom SQL.
{code}
SELECT `TableauSQL`.`address` AS `address`,
`TableauSQL`.`br` AS `br`,
`TableauSQL`.`first_visit` AS `first_visit`,
`TableauSQL`.`gender` AS `gender`,
`TableauSQL`.`id` AS `id`,
`TableauSQL`.`la` AS `la`,
`TableauSQL`.`name` AS `name`,
`TableauSQL`.`os` AS `os`,
`TableauSQL`.`st` AS `st`,
`TableauSQL`.`user_category` AS `user_category`
FROM (
select * from dfs.`default`.`/opt/drill/raw-files/click1.json`
) `TableauSQL`
{code}
But the query will failed.
Similarly, it will happen in other schema-less file types.
For example,
{code}
0: jdbc:drill:local=localhost:31010> select L_ORDERKEY from
cp.`tpch/lineitem.parquet` limit 1;
+------------+
| L_ORDERKEY |
+------------+
| 1 |
+------------+
1 row selected (0.835 seconds)
0: jdbc:drill:local=localhost:31010> select L_ORDERKEY from (select * from
cp.`tpch/lineitem.parquet` limit 1);
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while
running query.[error_id: "3a387934-9cca-4f3a-8f37-74cdca365113"
endpoint {
address: "localhost"
user_port: 31010
control_port: 31011
data_port: 31012
}
error_type: 0
message: "Failure while parsing sql. < ValidationException:[
org.eigenbase.util.EigenbaseContextException: From line 1, column 8 to line 1,
column 17 ] < EigenbaseContextException:[ From line 1, column 8 to line 1,
column 17 ] < SqlValidatorException:[ Column 'L_ORDERKEY' not found in any
table ]"
]
Error: exception while executing query (state=,code=0)
{code}
This will block using custom SQL for schema-less file in Tableau.
