Subject [jira] [Commented] (HIVE-8960) ParsingException in the WHERE statement with a Sub Query
Date Sat, 20 Aug 2016 10:12:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-8960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15429315#comment-15429315
] 

Vikash Pareek commented on HIVE-8960:
-------------------------------------

I am trying following query, it is working in Impala but not in Hive. 

SELECT t1.col1 FROM table1 t1 LEFT OUTER JOIN table2 t2 ON (t1.col2 = t2.col2 AND t1.col3
= t2.col3) 
WHERE t2.col4 = (SELECT MAX(t22.col4) FROM table2 t22 WHERE t22.col4 <= t1.col4);

Is there any alternative for this in Hive?

> Comparison with a Sub query in a WHERE statement does not work.
> Given that id_chargement is an integer:
> USE db1;
> SELECT * FROM tbl1 a WHERE a.id_chargement > (SELECT MAX(b.id_chargement) FROM tbl2
b);
> or
> SELECT * FROM tbl1 a WHERE a.id_chargement > (SELECT b.id_chargement FROM tbl2 b LIMIT
1);
> Both return the following parsing error:
> Error: Error while compiling statement: FAILED: ParseException line 1:88 cannot recognize
input near 'SELECT' 'b' '.' in expression specification (state=42000,code=40000)
