plsql中除數是否等於零？

-1

SELECT pstartdate, 
     opbal, 
     joined, 
     resign, 
     (opbal + joined - resign) clbal 
     , 
     (Round(((resign * 100)/(opbal + joined))/100, 2) * 100 
     ) attriation 
FROM (SELECT pstartdate, 
       penddate, 
       Getopempbal(pstartdate)   OpBal, 
       Getempjn(pstartdate, penddate) Joined, 
       Getempres(pstartdate, penddate) Resign 
     FROM (SELECT Add_months(:startdate, LEVEL - 1) pstartdate, 
         Add_months(:startdate, LEVEL) - 1 penddate 
       FROM dual 
       CONNECT BY LEVEL <= Months_between(:enddate, :startdate) + 1)) 
ORDER BY To_number(1)

當我執行此查詢錯誤來plsql中除數是否等於零？

除數爲零。

我認爲錯誤這個地方

(round(((resign*100)/(opbal+joined))/100,2)*100) attriation

錯誤是說你不能被0分割。那意味着opbal + joined = 0 – SaggingRufus

你使用的是MySQL，MS SQL Server還是Oracle？不要標記不涉及的產品。 – jarlh

格式正確。編輯時，標記代碼並點擊'{}'。 – jarlh

使用nullif獲取答案 –

問題 - 如錯誤所述 - 與除數一起使用，而不是divdend。你有錯誤的表達你的nullif。 –

我建議你在做除法時使用nullif()功能：

select . . . 
     (Round(((resign * 100)/nullif(opbal + joined, 0))/100, 2) * 100 
     ) attriation

這將返回NULL如果分母爲零。
