Hive query compare timestamp with unix_timestamp() and received error:ParseException missing ' at '>' near '<EOF>'

Question

I try to get the data in the past 3 second by compare the _timestamp and unix_timestamp() but got the error:

Error while compiling statement: FAILED: ParseException line 16:15 missing ' at '>' near '' line 17:16 missing ' at '<' near ''

select myInfo
from my_table
where _timestamp > unix_timestamp() * 1000 - 3000
and _timestamp  < unix_timestamp() * 1000

_timestamp looks like this "1674169604292" and it is epoch time in millisecond format. I know unix_timestamp() gives you epoch time in second format, that is why * 1000.

I have no clue what is missing based on the error message. Can anyone share some insight? Thank you.

Answer 1

You have to enclose _timestamp with backtick(`). Its not an issue with epoch timestamp.
Use below SQL -

select myInfo
from my_table
where `_timestamp` > unix_timestamp() * 1000 - 3000
and `_timestamp`  < unix_timestamp() * 1000
