Select first word in a MySQL query?
To select first word in MySQL query, you can use SUBSTRING_INDEX().
Following is the syntax −
select substring_index(yourColumnName,' ',1) as anyAliasName from yourTableName;
Let us first create a table −
mysql> create table DemoTable ( StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, StudentFullName varchar(40) ); Query OK, 0 rows affected (0.61 sec)
Insert records in the table using insert command −
mysql> insert into DemoTable(StudentFullName) values('John Smith');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable(StudentFullName) values('Carol Taylor');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable(StudentFullName) values('Bob Williams');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(StudentFullName) values('David Miller');
Query OK, 1 row affected (0.16 sec)Display records from the table using select command −
mysql> select *from DemoTable;
This will produce the following output −
+-----------+-----------------+ | StudentId | StudentFullName | +-----------+-----------------+ | 1 | John Smith | | 2 | Carol Taylor | | 3 | Bob Williams | | 4 | David Miller | +-----------+-----------------+ 4 rows in set (0.00 sec)
Following is the query to select first word in MySQL query −
mysql> select substring_index(StudentFullName,' ',1) as FirstWord from DemoTable;
This will produce the following output displaying the first word −
+-----------+ | FirstWord | +-----------+ | John | | Carol | | Bob | | David | +-----------+ 4 rows in set (0.00 sec)
