Redshift Extract Function issue

2019-07-19 00:41发布

While using this query:

 SELECT date_time 
 FROM test_table 
 where EXTRACT('epoch' FROM CONVERT_TIMEZONE(replace(timezone, '+', '-'),date_time::timestamp)) >= 1513036800 
   and EXTRACT('epoch' FROM CONVERT_TIMEZONE(replace(timezone, '+', '-'),date_time::timestamp)) <= 1513555200 
 limit 10

I am getting this error:

An error occurred when executing the SQL command:

[Amazon](500310) Invalid operation: Invalid data
Details: 
 -----------------------------------------------
  error:  Invalid data
  code:      8001
  context:   Invalid format or data given: 0000-00-00 00:00:00
  query:     1909217
  location:  funcs_timestamp.cpp:219
  process:   query1_59 [pid=25572]
  -----------------------------------------------;
1 statement failed.

Execution time: 0.63s

I am unable to use "Extract" function two times in a single query. I have tried to use "Between" as well. but that did not work.

If I remove one of any extract query from the date range. Then it would work.
