為此，請使用MySQL REPLACE()。讓我們首先創建一個表-mysql>?create?table?DemoTable

(

FolderLocation?text

);

使用插入命令在表中插入一些記錄-mysql>?insert?into?DemoTable?values('C/ProgramFiles/AllMySQLProgram');

mysql>?insert?into?DemoTable?values('C/ProgramFiles/JavaChatApplication');

mysql>?insert?into?DemoTable?values('C/ProgramFiles/Main/Image.png');

使用select語句顯示表中的所有記錄-mysql>?select?*from?DemoTable;

這將產生以下輸出-+------------------------------------+

|?FolderLocation?????????????????????|

+------------------------------------+

|?C/ProgramFiles/AllMySQLProgram?????|

|?C/ProgramFiles/JavaChatApplication?|

|?C/ProgramFiles/Main/Image.png??????|

+------------------------------------+

3?rows?in?set?(0.00?sec)

以下是在MySQL中執行查找和替換的查詢-mysql>?update?DemoTable

set?FolderLocation=replace(FolderLocation,'C/ProgramFiles','E/MyFolder/Details');

Rows?matched:?3?Changed?:?3?Warnings?:?0

讓我們再次檢查表記錄-mysql>?select?*from?DemoTable;

這將產生以下輸出-+----------------------------------------+

|?FolderLocation?????????????????????????|

+----------------------------------------+

|?E/MyFolder/Details/AllMySQLProgram?????|

|?E/MyFolder/Details/JavaChatApplication?|

|?E/MyFolder/Details/Main/Image.png??????|

+----------------------------------------+

3?rows?in?set?(0.00?sec)
