ORDER BY與內部查詢，給ORA-00907缺少右括號

Question

我想測試一個查詢並得到ORA-00907錯誤。我相信這個錯誤是由於我用於RUN.RN_RUN_ID的內部查詢。
內部查詢本身工作正常，我給內部查詢的結果，外部查詢工作正常。任何洞察我做錯了什麼，將不勝感激。

編碼風格和不必要的嵌套括號使這真的很難閱讀和解釋。但它也有幫助，與一些評論相反，ORA-00907並不總是意味着括號的數量不統一，而是可能表明更常見的語法錯誤導致解析器退出。在這種情況下，它不是很有幫助。

的問題是order by子句倒數第二行，你對與in比較子查詢中：

... 
AND RUN.RN_RUN_ID in(Select max(RUN.RN_RUN_ID) From (((((((RELEASES JOIN RELEASE_CYCLES 
... 
TEST.TS_TYPE = 'LR-SCENARIO')AND TEST.TS_TEST_ID =145965 
ORDER BY TESTCYCL.TC_TESTCYCL_ID) 
ORDER BY TESTCYCL.TC_TESTCYCL_ID,STEP.ST_STEP_ORDER 

最終排序顯然是允許的，但在子查詢事實並非如此。因此，它應該結束：

... 
TEST.TS_TYPE = 'LR-SCENARIO')AND TEST.TS_TEST_ID =145965) 
ORDER BY TESTCYCL.TC_TESTCYCL_ID,STEP.ST_STEP_ORDER 

我無法測試，當我沒有你的模式，但一個簡單的演示可以幫助演示：

select d1.dummy 
from dual d1 
where d1.dummy in (
    select dummy 
    from dual d2 
    order by d2.dummy 
) 
order by d1.dummy; 

Error at Command Line : 6 Column : 3 
Error report - 
SQL Error: ORA-00907: missing right parenthesis 
00907. 00000 - "missing right parenthesis" 

通過移除內`順序：

select d1.dummy 
from dual d1 
where d1.dummy in (
    select dummy 
    from dual d2 
) 
order by d1.dummy; 

DUMMY 
----- 
X  

它期待看到)的而不是order by，所以錯誤確實讓一些感覺，一旦你知道什麼是錯誤的;但它並不能真正幫助你縮小範圍。
