为此，请使用MySQLREPLACE()。让我们首先创建一个表-

mysql> create table DemoTable
(
   FolderLocation text
);

使用插入命令在表中插入一些记录-

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语句显示表中的所有记录-

mysql> select *from DemoTable;

这将产生以下输出-

+------------------------------------+
| FolderLocation                     |
+------------------------------------+
| C/ProgramFiles/AllMySQLProgram     |
| C/ProgramFiles/JavaChatApplication |
| C/ProgramFiles/Main/Image.png      |
+------------------------------------+
3 rows in set (0.00 sec)

以下是在MySQL中执行查找和替换的查询-

mysql> update DemoTable
   set FolderLocation=replace(FolderLocation,'C/ProgramFiles','E/MyFolder/Details');
Rows matched: 3 Changed : 3 Warnings : 0

让我们再次检查表记录-

mysql> select *from DemoTable;

这将产生以下输出-

+----------------------------------------+
| FolderLocation                         |
+----------------------------------------+
| E/MyFolder/Details/AllMySQLProgram     |
| E/MyFolder/Details/JavaChatApplication |
| E/MyFolder/Details/Main/Image.png      |
+----------------------------------------+
3 rows in set (0.00 sec)
