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)
