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; +----------------------+-----------------------+ | nrm_connect_time | left_nrm_connect_time | +======================+=======================+ | 2017-06-09 00:05:00 | -1-01-01 0 | | 2017-06-09 00:05:00 | -1-01-01 0 | | 2017-06-09 00:05:01 | -1-01-01 0 | | 2017-06-09 00:05:03 | -1-01-01 0 | | 2017-06-09 00:05:03 | -1-01-01 0 | +----------------------+-----------------------+ 5 tuples (29.802ms) sql>*SELECT DISTINCT* nrm_connect_time, LEFT(CAST(nrm_connect_time AS STRING),10) FROM NRM_20170609 LIMIT 5; +----------------------+------------+ | nrm_connect_time | L2 | +======================+============+ | 2017-06-09 00:05:00 | 2017-06-09 | | 2017-06-09 00:05:01 | 2017-06-09 | | 2017-06-09 00:05:03 | 2017-06-09 | | 2017-06-09 00:05:04 | 2017-06-09 | | 2017-06-09 00:05:05 | 2017-06-09 | +----------------------+------------+ 5 tuples (424.306ms)
*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)
