Get the substring of a column in MySQL
Use the SUBSTR() method to get the substring of a column.
Let us first create a table −
mysql> create table DemoTable -> ( -> Title text -> ); Query OK, 0 rows affected (0.74 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('This is a MySQL Database');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Java is an Object Oriented Programming Language');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable ;
Output
This will produce the following output −
+-------------------------------------------------+ | Title | +-------------------------------------------------+ | This is a MySQL Database | | Java is an Object Oriented Programming Language | +-------------------------------------------------+ 2 rows in set (0.00 sec)
Here is the query to select substring of a column −
mysql> SELECT distinct(substr(Title, 1, 8)) from DemoTable;
Output
This will produce the following output −
+-----------------------+ | (substr(Title, 1, 8)) | +-----------------------+ | This is | | Java is | +-----------------------+ 2 rows in set (0.00 sec)
