How to remove all instances of a specific character from a column in MySQL?
Let us first create a table −
mysql> create table DemoTable -> ( -> FirstName varchar(100) -> ); Query OK, 0 rows affected (0.41 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Adam^^^');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('^^^^^^^^Carol');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('Robert^^^^^^');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+---------------+ | FirstName | +---------------+ | Adam^^^ | | ^^^^^^^^Carol | | Robert^^^^^^ | +---------------+ 3 rows in set (0.00 sec)
Following is the query to remove all instances of a specific character from a column in MySQL. Here, we are removing all the instances of the special character ^ −
mysql> update DemoTable set FirstName=replace(FirstName,'^',''); Query OK, 3 rows affected (0.20 sec) Rows matched: 3 Changed: 3 Warnings: 0
