how to select data from hive with specific partition?

Question

everyone. here are the interactions with the hive:

hive> show partitions TABLENAME
pt=2012.07.28.08/is_complete=1
pt=2012.07.28.09/is_complete=1
pt=2012.07.28.10/is_complete=1
pt=2012.07.28.11/is_complete=1
hive> select * from TABLENAME where pt='2012.07.28.10/is_complete=1' limit 1;
OK

hive> select * from TABLENAME where pt='2012.07.28.10' limit 1;
OK

Time taken: 3.8 seconds
hive>

My question is that why the first select can't get the data?

Answer 1

"is_complete" is a column just like "pt" so the correct query is:

select * from TABLENAME where pt='2012.07.28.10' and is_complete='1' limit 1;
