Let us first create a table −
mysql> create table DemoTable828( CustomerName varchar(100), InterestRate varchar(100) ); Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable828 values('Chris','10%'); Query OK, 1 row affected (0.60 sec) mysql> insert into DemoTable828 values('Robert','11.5%'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable828 values('David','15.90%'); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable828 values('Bob','20%'); Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable828;
This will produce the following output −
+--------------+--------------+ | CustomerName | InterestRate | +--------------+--------------+ | Chris | 10% | | Robert | 11.5% | | David | 15.90% | | Bob | 20% | +--------------+--------------+ 4 rows in set (0.00 sec)
Following is the query to remove percentage sign from values in MySQL table −
mysql> update DemoTable828 set InterestRate=replace(InterestRate,'%',''); Query OK, 4 rows affected (0.18 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable828;
This will produce the following output −
+--------------+--------------+ | CustomerName | InterestRate | +--------------+--------------+ | Chris | 10 | | Robert | 11.5 | | David | 15.90 | | Bob | 20 | +--------------+--------------+ 4 rows in set (0.00 sec)
