日期格式问题，ORACLE

Question

I am writing this query, to find data between two dates. The time format I have is exactly like the one I am using in the query

    select TO_CHAR(REC_NO),(FIRSTNAME ||' '|| LASTNAME) as NAME,
           LOC_NAME,TO_CHAR(START_TIME,'yyyy/mm/dd/HH:MI:SS'),
           TO_CHAR(END_TIME,'yyyy/mm/dd/HH:MI:SS'),
           TT_NO,CUST_ID,CUST_MOB,MAC_ADDR,EMAIL_ID,s.STATUS 
     from vw_rtb_visit_assn v 
left join vu_issue_status@jiradb s on v.TT_NO = s.TICKETNUMBER  and TT_NO = '123' 
      and v.ASSN_TIME between to_date('Tue Dec 16 00:00:00 PKT 2014','yyyy/mm/dd')
      and to_date('Wed Dec 17 00:00:00 PKT 2014','yyyy/mm/dd')

My query doesn't execute and gives me a format exception.

Answer 1

your date are not in actual format of that particular character you pass in where condition

to_date('Tue Dec 16 00:00:00 PKT 2014','yyyy/mm/dd')

it should be

to_date('Tue Dec 16 00:00:00 PKT 2014','DY MON DD HH24:MI:SS TZD YYYY')

Answer 2

the format of DATE_IN_CHAR and FORMAT in to_date('DATE_IN_CHAR','FORMAT') should match.

kindly try the below

  and v.ASSN_TIME between to_date('2014/12/16','yyyy/mm/dd')
  and to_date('2014/12/17','yyyy/mm/dd')

Answer 3

Dates do not have formats. Formats are used for parsing strings as dates or generating strings from dates. You don't have to do any of these, you simply need to specify the interval as a date literal, as described in the documentation , eg:

  and v.ASSN_TIME between DATE '2014-12-16' AND DATE '2014-12-17'

Date literals are actual date values, not strings that have to be parsed using a specific format.

You can also specify TIMESTAMP literals with

TIMESTAMP '1997-01-31 09:26:50.124'

or

TIMESTAMP '1997-01-31 09:26:56.66 +02:00'

for a TIMESTAMP WITH TIMEZONE.
