訊息 8134，級別 16，狀態 1，第 1 行 遇到以零作除數錯誤
這兩天遇到一個非常奇怪的問題，給人的感覺有點匪夷所思，如下所示，在更新一個表的統計資訊時，會遇到“遇到以零作除數錯誤”，本來這個錯誤是屬於數學錯誤，但是居然出現在更新統計資訊的SQL語句裡面
UPDATE STATISTICS [dbo].[FIInspectFabric] SAMPLE 20 PERCENT;
訊息 8134，級別 16，狀態 1，第 1 行
遇到以零作除數錯誤。
UPDATE STATISTICS [dbo].[FIInspectFabric] WITH FULLSCAN;
訊息 8134，級別 16，狀態 1，第 1 行
遇到以零作除數錯誤。
如果我更新統計資訊的SQL語句不帶引數，則會執行成功。如下所示
UPDATE STATISTICS [dbo].[FIInspectFabric];
DBCC CHECKTABLE('FIInspectFabric')也沒有發現任何問題，Google、Bing搜尋了很久也沒有查到相關資料。
問題出在哪裡？一直沒有答案。直到我檢查這個表的索引時，發現在表FIInspectFabric的欄位A、B上建立了主鍵索引、然後不知道那個程式設計師又在欄位A上建立了兩個索引（嚴重鄙視之），於是刪除了這兩個索引後，重新執行上面語句OK,問題消失了，於是我建立了測試表，想重現這個錯誤，很奇怪，怎麼也重現不了這個錯誤。

今天又出現了這個錯誤，重建索引後，問題依然存在，在檢查這個表的統計資訊時，發現除了索引對應的統計資訊外，還有大量額外的統計資訊，於是我將這些統計資訊全部刪除（系統會根據需要自動建立）。然後去跟新統計資訊，問題解決。

今天同事反饋在SELECT這個表的時候也遇到了這個錯誤，我立馬想到了可能是有計算列的問題，檢查了一下表結構，發現有一個欄位確實是用其它列計算，終於解開了這個案例的謎底！ 只是在這種機緣巧合的情況下，總有點怪怪的感覺，試想，如果當時檢查一下表結構，也許就能解開真相了！
[HundredYard_Points] AS (case when [Quantity]=(0) then (0) else floor(((isnull([Total_Def_Point_SendedYorn],[Total_Def_Point])*(3600))/(isnull([Width],(1))*(isnull([Quantity],(1))-isnull([Allow_Quantity],(0)))))*(100))/(100) end)
