的Oracle SQL條件時，

-1

我需要幫助搞清楚如何定義conndition只在特定的值取決於從列的Oracle SQL條件時，

WHERE ((CUSTOMFIELDVALUE.STRINGVALUE=TO_CHAR(CUSTOMFIELDOPTION.ID)) {?} (CUSTOMFIELD.CFNAME='Type of workload') AND CUSTOMFIELDOPTION.CUSTOMVALUE='Performed')

條件(CUSTOMFIELDVALUE.STRINGVALUE=TO_CHAR(CUSTOMFIELDOPTION.ID))當CUSTOMFIELD.CFNAME是(CUSTOMFIELD.CFNAME='Type of workload')

感謝您應該只適用提前。

（1）用你正在使用的數據庫標記你的問題。（2）提供樣本數據和期望的結果。 –

據我理解你的問題：

WHERE (CUSTOMFIELDVALUE.STRINGVALUE = TO_CHAR(CUSTOMFIELDOPTION.ID) 
     AND CUSTOMFIELD.CFNAME = 'Type of workload' 
     AND CUSTOMFIELDOPTION.CUSTOMVALUE = 'Performed') 
     OR 
     ((CUSTOMFIELD.CFNAME IS NULL OR CUSTOMFIELD.CFNAME <> 'Type of workload') 
     AND CUSTOMFIELDOPTION.CUSTOMVALUE = 'Performed')

這可以被改寫：

WHERE CUSTOMFIELDOPTION.CUSTOMVALUE = 'Performed' 
     AND ((CUSTOMFIELDVALUE.STRINGVALUE = TO_CHAR(CUSTOMFIELDOPTION.ID) 
      AND CUSTOMFIELD.CFNAME = 'Type of workload' 
      ) 
      OR 
      ((CUSTOMFIELD.CFNAME IS NULL OR CUSTOMFIELD.CFNAME <> 'Type of workload'))

對不起，延遲迴復，並感謝您的建議。你重寫的查詢非常接近我所需要的，但最後我沒有正確的結果。 –

我可以爲您提供完整的查詢，我的最終目標是什麼。 –

試着用清晰的方式解釋它，並帶有示例數據（在創建表和插入示例數據後）和期望的結果請 – etsa

我會使用UNION運算符與2個不同的查詢

SELECT * FROM TABLE WHERE CUSTOMFIELD.CFNAME='Type of workload' AND CUSTOMFIELDVALUE.STRINGVALUE=TO_CHAR(CUSTOMFIELDOPTION.ID) AND AND CUSTOMFIELDOPTION.CUSTOMVALUE='Performed' 
UNION 
SELECT * FROM TABLE WHERE CUSTOMFIELD.CFNAME<>'Type of workload' AND CUSTOMFIELDOPTION.CUSTOMVALUE='Performed'

希望這幫助

這是完整的查詢，目標是在執行工作負載類型和接受解決方案（RESOLUTION = 8）時，爲特定問題提供所有可用字段的列表。

存在的問題是，其僅具有用於

條件CUSTOMVALUE = '' 進行用於CUSTOMFIELD.CFNAME = '工作量的類型' 將要使用的條件：

AND (CUSTOMFIELDVALUE.STRINGVALUE=TO_CHAR(CUSTOMFIELDOPTION.ID) AND CUSTOMFIELDOPTION.CUSTOMVALUE='Performed')

整個查詢：

SELECT DISTINCT 
    JIRAISSUE.ISSUENUM, 
    JIRAISSUE.SUMMARY, 
    PROJECT.PNAME, 
    CUSTOMFIELD.CFNAME, 
    CUSTOMFIELDVALUE.STRINGVALUE, 
    CUSTOMFIELDVALUE.ID, 
    CUSTOMFIELDVALUE.NUMBERVALUE, 
    CUSTOMFIELDOPTION.CUSTOMVALUE, 
    ISSUETYPE.PNAME 
FROM 
    JIRAISSUE, 
    PROJECT, 
    CUSTOMFIELDVALUE, 
    CUSTOMFIELD, 
    CUSTOMFIELDOPTION, 
    ISSUETYPE 
WHERE (CUSTOMFIELDVALUE.ISSUE=JIRAISSUE.ID) 
    AND (CUSTOMFIELDVALUE.CUSTOMFIELD=CUSTOMFIELD.ID) 
    AND (CUSTOMFIELD.ID=CUSTOMFIELDOPTION.CUSTOMFIELD) 
    AND (CUSTOMFIELDOPTION.CUSTOMFIELD=CUSTOMFIELDVALUE.CUSTOMFIELD) 
    AND (JIRAISSUE.ISSUETYPE=ISSUETYPE.ID ) 
    AND (PROJECT.ID=JIRAISSUE.PROJECT ) 
    AND CUSTOMFIELD.CFNAME IN ('Type of workload', 'ANA-PROG extramuros','ANA-PROG intramuros','TEC-CONS extramuros','TEC-CONS intramuros','PRO-MAN extramuros','PRO-MAN intramuros' ) 
    AND PROJECT.PNAME IN ('eNotices', 'TED Applications', 'TED Web Services', 'TED-Monitor-2012', 'eTendering' ) 
    AND (CUSTOMFIELDVALUE.STRINGVALUE=TO_CHAR(CUSTOMFIELDOPTION.ID) AND CUSTOMFIELDOPTION.CUSTOMVALUE='Performed') 
    AND JIRAISSUE.RESOLUTION=8 
ORDER by issuenum;
