How to split string in MySQL using SUBSTRING_INDEX?

Let us first create a table −

mysql> create table DemoTable1465
   -> (
   -> Name varchar(40)
   -> );
Query OK, 0 rows affected (0.54 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1465 values('Chris Brown');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1465 values('David Miller');
Query OK, 1 row affected (0.26 sec)
mysql> insert into DemoTable1465 values('John Doe');
Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1465;

This will produce the following output −

+--------------+
| Name         |
+--------------+
| Chris Brown  |
| David Miller |
| John Doe     |
+--------------+
3 rows in set (0.00 sec)

Following is the query to split string in MySQL using SUBSTRING_INDEX(). Here, we are splitting first and last name strings −

mysql> select
   -> substring_index(substring_index(Name, ' ', 1), ' ', -1) as StudentFirstName,
   ->   substring_index(substring_index(Name, ' ', 3), ' ', -1) AS StudentLastName
   -> from DemoTable1465;

This will produce the following output −

+------------------+-----------------+
| StudentFirstName | StudentLastName |
+------------------+-----------------+
| Chris            |           Brown |
| David            |          Miller |
| John             |             Doe |
+------------------+-----------------+
