How to remove partial text from value in MySQL?

In order to remove partial text from value, you can use REPLACE() from MySQL. Following is the syntax −

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

Let us first create a table −

mysql> create table removePartialTextDemo    -> (    -> JavaVersionDetails varchar(100)    -> ); Query OK, 0 rows affected (0.51 sec)

Following is the query to insert some records in the table using insert command −

mysql> insert into removePartialTextDemo values('Java Version 1.0'); Query OK, 1 row affected (0.50 sec) mysql> insert into removePartialTextDemo values('Java Version 1.1'); Query OK, 1 row affected (0.23 sec) mysql> insert into removePartialTextDemo values('Java Version 1.2'); Query OK, 1 row affected (0.16 sec) mysql> insert into removePartialTextDemo values('Java Version 1.3'); Query OK, 1 row affected (0.27 sec) mysql> insert into removePartialTextDemo values('Java Version 1.4'); Query OK, 1 row affected (0.15 sec) mysql> insert into removePartialTextDemo values('Java Version 7'); Query OK, 1 row affected (0.11 sec)

Following is the query to display all records from the table using select statement −

mysql> select * from removePartialTextDemo;

This will produce the following output −

+--------------------+ | JavaVersionDetails | +--------------------+ | Java Version 1.0   | | Java Version 1.1   | | Java Version 1.2   | | Java Version 1.3   | | Java Version 1.4   | | Java Version 7     | +--------------------+ 6 rows in set (0.00 sec)

Here is the query to remove partial text from value. We are separating the version number here −

mysql> update removePartialTextDemo set JavaVersionDetails = replace(JavaVersionDetails,'Java Version ',''); Query OK, 6 rows affected (0.09 sec) Rows matched: 6 Changed: 6 Warnings: 0

Let us display all records from the table to check the partial text have been removed −

mysql> select * from removePartialTextDemo;

This will produce the following output −

+--------------------+ | JavaVersionDetails | +--------------------+ | 1.0                | | 1.1                | | 1.2                | | 1.3 | | 1.4 | | 7 | +--------------------+ 6 rows in set (0.00 sec)
