Alexander Pivovarov updated HIVE-9528:
--------------------------------------
Description:
When running the following query:
{code}
SELECT if( COUNT(*) = 0, 'true', 'false' ) as RESULT FROM ( select * from sim
a join sim2 b on a.simstr=b.simstr) app
Error: Error while compiling statement: FAILED: SemanticException [Error
10007]: Ambiguous column reference simstr in app (state=42000,code=10007)
{code}
This query works fine in hive 0.10
In the apache trunk, following workaround will work:
{code}
SELECT if(COUNT(*) = 0, 'true', 'false') as RESULT FROM (select a.* from sim a
join sim2 b on a.simstr=b.simstr) app;
{code}
