Can we use str_replace in MySQL?
The str_replace version in MySQL is the replace() function. Let us first create a table to understand the function −
mysql> create table StringReplaceDemo −> ( −> Id int, −> URL varchar(200) −> ); Query OK, 0 rows affected (0.38 sec)
Insert some records in the table with the help of insert command. The query is as follows −
mysql> insert into StringReplaceDemo values(1001,'https://www.google.co.in'); Query OK, 1 row affected (0.09 sec) mysql> insert into StringReplaceDemo values(1002,'https://www.facebook.com'); Query OK, 1 row affected (0.11 sec) mysql> insert into StringReplaceDemo values(1003,'https://mail.google.com'); Query OK, 1 row affected (0.12 sec)
Display all records from the table using the following query −
mysql> select *from StringReplaceDemo;
The following is the output −
+------+--------------------------+ | Id | URL | +------+--------------------------+ | 1001 | https://www.google.co.in | | 1002 | https://www.facebook.com | | 1003 | https://mail.google.com | +------+--------------------------+ 3 rows in set (0.00 sec)
Look at the above sample output. We will now replace the word ‘mail’ with ‘www’. The query is as follows −
mysql> update StringReplaceDemo set URL = replace(URL,'mail','www') where URL like '%mail%'; Query OK, 1 row affected (0.15 sec) Rows matched: 1 Changed: 1 Warnings: 0
Now let us check the word mail is replaced or not. The query is as follows −
mysql> select *from StringReplaceDemo;
The following is the output displaying that we have successfully performed replace −
+------+--------------------------+ | Id | URL | +------+--------------------------+ | 1001 | https://www.google.co.in | | 1002 | https://www.facebook.com | | 1003 | https://www.google.com | +------+--------------------------+ 3 rows in set (0.00 sec)
