How to separate last name and first names in single column into two new columns in MySQL?
For this, use SUBSTRING_INDEX() and REPLACE(). Let us first create a table −
mysql> create table DemoTable (Name varchar(100));
Query OK, 0 rows affected (0.53 sec)
Insert some records in the table using insert command. Here, we have inserted last name and first names −
mysql> insert into DemoTable values('Chris | Bob Brown');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable values('Carol | Robert Taylor');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable values('Sam | David Miller');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-----------------------+
| Name |
+-----------------------+
| Chris | Bob Brown |
| Carol | Robert Taylor |
| Sam | David Miller |
+-----------------------+
3 rows in set (0.00 sec)
Following is the query to separate last name and first names into two new columns in MySQL −
mysql> SELECT REPLACE(Name, SUBSTRING_INDEX(Name, ' ', -1),'')
AS FirstName, SUBSTRING_INDEX(Name, ' ', -1) AS LastName from DemoTable;
This will produce the following output −
+-----------------+----------+
| FirstName | LastName |
+-----------------+----------+
| Chris | Bob | Brown |
| Carol | Robert | Taylor |
| Sam | David | Miller |
+-----------------+----------+
3 rows in set (0.00 sec)
