Is it possible to delete everything after a 'space' in a MySQL field?
In order to delete everything after a space, you need to use SUBSTRING_INDEX().
The syntax is as follows
select substring_index(yourColumnName,' ',1) as anyAliasName from yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows
mysql> create table deleteAfterSpaceDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(100) -> ); Query OK, 0 rows affected (0.55 sec)
Insert some records in the table using insert command.
The query is as follows
mysql> insert into deleteAfterSpaceDemo(StudentName) values('John Smith');
Query OK, 1 row affected (0.15 sec)
mysql> insert into deleteAfterSpaceDemo(StudentName) values('Adam Smith');
Query OK, 1 row affected (0.14 sec)
mysql> insert into deleteAfterSpaceDemo(StudentName) values('Carol Taylor');
Query OK, 1 row affected (0.18 sec)
mysql> insert into deleteAfterSpaceDemo(StudentName) values('Chris Brown');
Query OK, 1 row affected (0.14 sec)
mysql> insert into deleteAfterSpaceDemo(StudentName) values('David Miller');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement.
The query is as follows
mysql> select *from deleteAfterSpaceDemo;
The following is the output
+----+--------------+ | Id | StudentName | +----+--------------+ | 1 | John Smith | | 2 | Adam Smith | | 3 | Carol Taylor | | 4 | Chris Brown | | 5 | David Miller | +----+--------------+ 5 rows in set (0.00 sec)
Here is the query to delete everything after a space
mysql> select substring_index(StudentName,' ',1) as deleteAllAfterSpace from deleteAfterSpaceDemo;
The following is the output
+---------------------+ | deleteAllAfterSpace | +---------------------+ | John | | Adam | | Carol | | Chris | | David | +---------------------+ 5 rows in set (0.04 sec)
