SQL使用替換技術更新各種行

Question

我需要在我有的表中解決SQL中的問題。

我有一個表有不同的列（也有各種行）有一個路線。 I.E.

E：\ file.xml

我需要做的是，檢查至少10列是何其相似，並搜索爲E開頭的單詞：\並替換爲C吧：

是否有一個查詢可以幫助我做到這一點？或者我將不得不一一編輯（因爲我不認爲這是最聰明的方式）。

UPDATE： 表結構

如果要更新，實際上具有任何價值至極每列隨e開頭：

UPDATE [CCARD_corporatives] 
SET pathCFD = CASE 
      WHEN pathCFD LIKE 'e:\%' 
      THEN REPLACE(pathCFD,'e:\','c:\') 
      ELSE pathCFD 
      END, 
     pathCertificateCFD = CASE 
         WHEN pathCertificateCFD LIKE 'e:\%' 
         THEN REPLACE(pathCertificateCFD,'e:\','c:\') 
         ELSE pathCertificateCFD 
        END, 
     pathPrivateKeyCFD = CASE 
         WHEN pathPrivateKeyCFD LIKE 'e:\%' 
         THEN REPLACE(pathPrivateKeyCFD,'e:\','c:\') 
         ELSE pathPrivateKeyCFD 
        END;
