Athena does not recognize date functions

Question

Hi,  
  
I have date in one of the table columns in the format "8/14/2017". I get an error when I use the function from_unixtime to convert it into ISO time date.  
  
The query I am  using is  
--------------------------  
select TO_DATE(from_unixtime(UNIX_TIMESTAMP('07/03/2013', 'yyyy-mm-dd')))  
-------------------------  
The following is the error:: Can you please take a look at this  
---------  
Your query has the following error(s):  
SYNTAX_ERROR: line 1:30: Function unix_timestamp not registered  
  
thanks,  
sharu

Answer

Not sure if these just renamed since you tried but unix_timestamp is not listed on the date functions in Presto - https://prestodb.io/docs/current/functions/datetime.html - you could do to_unixtime though but it takes a timestamp. Given the original query the unixtime stuff looks unnecessary, you could just use date_parse e.g. date_parse('07/03/2013', 'yyyy-mm-dd')

I have this same problem. Does anybody have an answer?
