MySQL 如何查找和替换具有文件路径的列

因此，使用MySQL REPLACE()。让我们首先创建一个表 −

mysql> create table DemoTable
(
   FolderLocation text
);
Query OK, 0 rows affected (0.80 sec)

使用插入命令在表中插入一些记录 −

mysql> insert into DemoTable values('C/ProgramFiles/AllMySQLProgram');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('C/ProgramFiles/JavaChatApplication');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('C/ProgramFiles/Main/Image.png');
Query OK, 1 row affected (0.18 sec)

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');
Query OK, 3 rows affected (0.14 sec)
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)
