也能收到ORA-00933：SQL命令不能正確地結束

Question

我想現在解決這個查詢了一段時間，我不斷收到錯誤：

ORA-00933: SQL command not properly ended

什麼我可以做錯誤的任何提示。

SELECT ACTIVITY_APPROVAL_DATE, COUNT(*)AS ACTIVITY_COUNT 
FROM ACTIVITY 
WHERE ACTIVITY_APPROVAL_DATE = CURRENT_DATE() 
GROUP BY ACTIVITY_APPROVAL_DATE; 

Answer 1

從CURRENT_DATE()

SELECT ACTIVITY_APPROVAL_DATE, COUNT(*)AS ACTIVITY_COUNT 
FROM ACTIVITY 
WHERE ACTIVITY_APPROVAL_DATE = CURRENT_DATE 
GROUP BY ACTIVITY_APPROVAL_DATE; 

Answer 2

刪除()如果這是Oracle，然後用sysdate：

SELECT ACTIVITY_APPROVAL_DATE, COUNT(*)AS ACTIVITY_COUNT 
FROM ACTIVITY 
WHERE ACTIVITY_APPROVAL_DATE = TRUNC(sysdate) 
GROUP BY ACTIVITY_APPROVAL_DATE; 

如果ACTIVITY_APPROVAL_DATE有時間組件，那麼你需要考慮到這一點：

SELECT ACTIVITY_APPROVAL_DATE, COUNT(*)AS ACTIVITY_COUNT 
FROM ACTIVITY 
WHERE ACTIVITY_APPROVAL_DATE >= TRUNC(sysdate) AND 
     ACTIVITY_APPROVAL_DATE < TRUNC(sysdate + 1) 
GROUP BY ACTIVITY_APPROVAL_DATE;
