How to split a column in MySQL?
To split a column, you need to use SUBSTRING_INDEX() in MySQL. Let us first create a table −
mysql> create table DemoTable -> ( -> Name varchar(40) -> ); Query OK, 0 rows affected (1.80 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John_Smith');
Query OK, 1 row affected (0.36 sec)
mysql> insert into DemoTable values('Carol_Taylor');
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable values('David_Miller');
Query OK, 1 row affected (0.54 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+--------------+ | Name | +--------------+ | John_Smith | | Carol_Taylor | | David_Miller | +--------------+ 3 rows in set (0.00 sec)
Following is the query to split a column in MySQL −
mysql> select if(locate('_',Name)=0,'',substring_index(Name, '_', 1)) from DemoTable;
This will produce the following output:
+---------------------------------------------------------+
| if(locate('_',Name)=0,'',substring_index(Name, '_', 1)) |
+---------------------------------------------------------+
| John |
| Carol |
| David |
+---------------------------------------------------------+
3 rows in set (0.00 sec)
