-------------------------------------------------------------------
I would like to complete information given in the description of the ticket :
I'm using Hive 1.2.1000.2.6.0.3-8.
I think this bug could come from the patch of this ticket
https://issues.apache.org/jira/browse/HIVE-15970 and more particulary the
snippet of code below :
{code:java}
throw new IllegalStateException("Expected '" + getMatchedText(curNode) + "' to
be in sub-query or set operation.");
{code}
[https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/Context.java]
{code:java}
/**
* The suffix is always relative to a given ASTNode
*/
public DestClausePrefix getDestNamePrefix(ASTNode curNode) {
assert curNode != null : "must supply curNode";

//select statement
assert curNode.getType() == HiveParser.TOK_DESTINATION;
if(operation == Operation.OTHER) {
//not an 'interesting' op
return DestClausePrefix.INSERT;
}
//if it is an 'interesting' op but it's a select it must be a sub-query

> Project: Hive
> Issue Type: Bug
> Reporter: Frédéric ESCANDELL
> Priority: Blocker
>
> Hi,
> I based my DDL on this exemple
> https://fr.hortonworks.com/tutorial/using-hive-acid-transactions-to-insert-update-and-delete-data/.
> In a delete request, the use of a view in a subquery throw an exception :
> FAILED: IllegalStateException Expected 'insert into table default.mydim
> select ROW__ID from default.mydim sort by ROW__ID' to be in sub-query or set
> operation.
> {code}
> {code:sql}
> drop table if exists mydim;
> create table mydim (key int, name string, zip string, is_current boolean)
> clustered by(key) into 3 buckets
> stored as orc tblproperties ('transactional'='true');
> insert into mydim values
> (1, 'bob', '95136', true),
> (2, 'joe', '70068', true),
> (3, 'steve', '22150', true);
> drop table if exists updates_staging_table;
> create table updates_staging_table (key int, newzip string);
> insert into updates_staging_table values (1, 87102), (3, 45220);
> drop view if exists updates_staging_view;
> create view updates_staging_view (key, newzip) as select key, newzip from
> updates_staging_table;
> delete from mydim
> where mydim.key in (select key from updates_staging_view);
> FAILED: IllegalStateException Expected 'insert into table default.mydim
