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)
