Apostrophe replacement in MySQL query?

To replace apostrophe, you can use replace(). Following is the syntax −

update yourTableName set yourColumnName=replace(yourColumnName,'\'','');

Let us first create a table −

mysql> create table DemoTable    (    Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,    Sentence varchar(100)    ); Query OK, 0 rows affected (0.17 sec)

Insert some records in the table using insert command. Apostrophe is added for the sentence −

mysql> insert into DemoTable(Sentence) values('Chris\'s Father'); Query OK, 1 row affected (0.07 sec) mysql> insert into DemoTable(Sentence) values('Larry\'s Mother'); Query OK, 1 row affected (0.06 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+----------------+ | Id | Sentence | +----+----------------+ | 1 | Chris's Father | | 2 | Larry's Mother | +----+----------------+ 2 rows in set (0.00 sec)

Following is the query to replace apostrophe −

mysql> update DemoTable set Sentence=replace(Sentence,'\'',''); Query OK, 2 rows affected (0.07 sec) Rows matched: 2 Changed: 2 Warnings: 0

Let us display records from the table to check apostrophe have been replaced or not.

mysql> select *from DemoTable;

This will produce the following output −

+----+---------------+ | Id | Sentence | +----+---------------+ | 1 | Chriss Father | | 2 | Larrys Mother | +----+---------------+ 2 rows in set (0.00 sec)
