-------------------------------------
Summary: Hive2: float value need to be single quoted inside where
clause to return rows when it doesn't have to be
Key: HIVE-13928
URL: https://issues.apache.org/jira/browse/HIVE-13928
Project: Hive
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Takahiko Saito
The below select where with float value does not return any row:
{noformat}
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> drop table test;
No rows affected (0.212 seconds)
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> create table test (f float);
No rows affected (1.131 seconds)
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> insert into table test values
(-35664.76),(29497.34);
No rows affected (2.482 seconds)
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test;
+------------+--+
| test.f |
+------------+--+
| -35664.76 |
| 29497.34 |
+------------+--+
2 rows selected (0.142 seconds)
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test where f =
-35664.76;
+---------+--+
| test.f |
+---------+--+
+---------+--+
{noformat}
The workaround is to single quote float value:
{noformat}
0: jdbc:hive2://os-r7-mvjkcu-hiveserver2-11-4> select * from test where f =
'-35664.76';
+------------+--+
| test.f |
+------------+--+
| -35664.76 |
+------------+--+
1 row selected (0.163 seconds)
{noformat}
