How can I find and replace in MySQL in a column with file path?
For thus, use MySQL REPLACE(). Let us first create a table −
mysql> create table DemoTable
(
FolderLocation text
);
Query OK, 0 rows affected (0.80 sec)
Insert some records in the table using insert command −
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)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------------------------------+
| FolderLocation |
+------------------------------------+
| C/ProgramFiles/AllMySQLProgram |
| C/ProgramFiles/JavaChatApplication |
| C/ProgramFiles/Main/Image.png |
+------------------------------------+
3 rows in set (0.00 sec)
Following is the query to perform find and replace in MySQL −
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
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+----------------------------------------+
| FolderLocation |
+----------------------------------------+
| E/MyFolder/Details/AllMySQLProgram |
| E/MyFolder/Details/JavaChatApplication |
| E/MyFolder/Details/Main/Image.png |
+----------------------------------------+
3 rows in set (0.00 sec)
