Hi!

May be someone can help me, Im facing the following problem.

Im trying to pull some information from the field nrm_connect_time, I tried almost all the date/timestamp functions, but all of them failed.

Finally, I decided to CAST as STRING, and see what happends...

If I do a SELECT DISTINCT .. then I have the correct information, if I dont include the DISTINCT what I see has nonsense...

sql>SELECT nrm_connect_time, LEFT(CAST(nrm_connect_time AS STRING),10) FROM NRM_20170609 LIMIT 5;

+----------------------+-----------------------+

The "nrm_connect_time"  is defined as TIMESTAMP(0).

Let me show you a differente example:

sql>SELECT DISTINCT nrm_connect_time, LEFT(CAST(nrm_connect_time AS STRING),10), timestamp_to_str(nrm_connect_time, '%Y') FROM NRM_20170609 LIMIT 5;

+----------------------+------------+------+

| nrm_connect_time     | L2         | L3   |

+======================+============+======+

| 2017-06-09 00:05:00  | 2017-06-09 | 2017 |

| 2017-06-09 00:05:01  | 2017-06-09 | 2017 |

| 2017-06-09 00:05:03  | 2017-06-09 | 2017 |

| 2017-06-09 00:05:04  | 2017-06-09 | 2017 |

| 2017-06-09 00:05:05  | 2017-06-09 | 2017 |

+----------------------+------------+------+

5 tuples (707.217ms)

sql>SELECT  nrm_connect_time, LEFT(CAST(nrm_connect_time AS STRING),10), timestamp_to_str(nrm_connect_time, '%Y') FROM NRM_20170609 LIMIT 5;

TypeException:user.s16_55[123]:'mtime.timestamp_to_str' undefined in:     mtime.timestamp_to_str(X_196:oid,A1:str);

program contains errors
