How can I replace & with an ampersand in my MySQL database?
To replace & with an ampersand, use MySQL REPLACE(). Let us first create a table −
mysql> create table DemoTable( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Value varchar(100) ); Query OK, 0 rows affected (1.06 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(Value) values('@amp'); Query OK, 1 row affected (0.33 sec) mysql> insert into DemoTable(Value) values('&'); Query OK, 1 row affected (1.09 sec) mysql> insert into DemoTable(Value) values('#amp'); Query OK, 1 row affected (0.28 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+-------+ | Id | Value | +----+-------+ | 1 | @amp | | 2 | & | | 3 | #amp | +----+-------+ 3 rows in set (0.00 sec)
Following is the query to replace & with ampersand −
mysql> update DemoTable set Value=replace(Value,'&','&'); Query OK, 1 row affected (0.56 sec) Rows matched: 3 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+----+-------+ | Id | Value | +----+-------+ | 1 | @amp | | 2 | & | | 3 | #amp | +----+-------+ 3 rows in set (0.00 sec)
