这是我在Oracle 10g上执行的查询。这对我来说是一种奇怪的行为。当我使用任一连接执行select查询时，它可以正常工作，但是对于两个必需的连接，它都显示为ora-01861 literal does not match format string。

Error report:
SQL Error: ORA-01861: literal does not match format string
01861. 00000 -  "literal does not match format string"
*Cause:    Literals in the input must be the same length as literals in
           the format string (with the exception of leading whitespace).  If the
           "FX" modifier has been toggled on, the literal must match exactly,
           with no extra whitespace.
*Action:   Correct the format string to match the literal.

Answer 1

这似乎是数据库中的一个错误。无论如何，尝试将'1-JUL-'替换为'01 -JUL-'等等。你的select在ELSE子句中使用隐式格式转换to_char（contract.ANNOUNCEMENT_DATE），这也可能是一个问题。

我会重写select以尽可能避免转换，比如

select contract.contract_id
from 
  (select contract_id, customer_company_id, vendor_company_id,
          nvl(ANNOUNCEMENT_DATE, 
              add_months(trunc(to_date(ANNOUNCEMENT_YEAR,'yyyy'),'yyyy'),
                 case when contract.ANNOUNCEMENT_QUARTER='Q1' then 0
                      when contract.ANNOUNCEMENT_QUARTER='Q1' then 3
                      when contract.ANNOUNCEMENT_QUARTER='Q1' then 6
                      when contract.ANNOUNCEMENT_QUARTER='Q1' then 9
                 end)) quarter_start
     from swcd.scd_contract) contract
left join SCD.COMPANY_TIMELINE_VIEW customer on
  (customer.company_id=contract.customer_company_id and
   contract.quarter_start between  nvl(trunc(customer.EVENT_START_DATE), to_date('01-JAN-1901', 'DD-Mon-YYYY')) AND
                                   nvl(trunc(customer.EVENT_END_DATE, to_date('01-JAN-2101', 'DD-Mon-YYYY')))) 
left join SCD.COMPANY_TIMELINE_VIEW vendor on
  (vendor.company_id=contract.vendor_company_id and
   contract.quarter_start between  nvl(trunc(vendor.EVENT_START_DATE), to_date('01-JAN-1901', 'DD-Mon-YYYY')) AND
                                   nvl(trunc(vendor.EVENT_END_DATE, to_date('01-JAN-2101', 'DD-Mon-YYYY'))));

select contract.contract_id

left join SCD.COMPANY_TIMELINE_VIEW customer on (customer.company_id=contract.customer_company_id and to_char(to_date(case when contract.ANNOUNCEMENT_DATE is null then case when contract.ANNOUNCEMENT_QUARTER='Q1' then '01-JAN-' when contract.ANNOUNCEMENT_QUARTER='Q2' then '01-APR-'

trunc(customer.EVENT_END_DATE) END) 
and contract.customer_company_id is not null)

left join SCD.COMPANY_TIMELINE_VIEW vendor on (vendor.company_id=contract.vendor_company_id and to_char(to_date(case when contract.ANNOUNCEMENT_DATE is null then case when contract.ANNOUNCEMENT_QUARTER='Q1' then '01-JAN-' when contract.ANNOUNCEMENT_QUARTER='Q2' then '01-APR-'

trunc(vendor.EVENT_START_DATE) END) AND to_char(to_date(case when contract.ANNOUNCEMENT_DATE is null then case when contract.ANNOUNCEMENT_QUARTER='Q1' then '01-JAN-' when contract.ANNOUNCEMENT_QUARTER='Q2' then '01-APR-'
when contract.ANNOUNCEMENT_QUARTER='Q3' then '01-JUL-' when contract.ANNOUNCEMENT_QUARTER='Q4' then '01-OCT-' end || contract.ANNOUNCEMENT_YEAR else to_char(contract.ANNOUNCEMENT_DATE) end),'dd-MON-YYYY') <= (CASE WHEN vendor.EVENT_END_DATE is null THEN to_date('01-JAN-2101', 'DD-Mon-YYYY') else 
trunc(vendor.EVENT_END_DATE) END) 
and contract.vendor_company_id is not null);

加入条款中的工作正常，id列面临null比较问题。所以在is not null子句中添加了join，现在效果很好。
