Change a decimal string into a timestamp in Impala
How do you convert a string type like
t1.updte_timestamp
2018-06-02-08.18.45.562742
2018-05-26-09.18.16.594824
into a timestamp? SHOULD RESULT IN:
2018-06-02-08.18.45
2018-05-26-09.18.16
ETC
The values had been imported from excel and are in STRING-TYPE
I tried:
SELECT
to_timestamp(cast (t1.updte_timestamp as string), 'yyyy-mm-dd hh:mm:ss') as updted_timestamp FROM OLD;
but results in NULL for all values
thank you

why don't you just take a length=19 prefix out of the timestamp?substr(value, 1, 19)

substr(value, 1, 19)– mangusta

you can substr your string and apply to_timestamp as follow
select to_timestamp(substr('2018-06-02-08.18.45.562742', 1, 19) , 'yyyy-MM-dd-HH.mm.ss');
Make sure you use MM for month and HH for hour in upper case
