Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Code varchar(100)
   -> );
Query OK, 0 rows affected (1.07 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('/101/102/106');
Query OK, 1 row affected (0.14 sec)

mysql> insert into DemoTable values('/110/111/101');
Query OK, 1 row affected (0.14 sec)

mysql> insert into DemoTable values('/111/114/201');
Query OK, 1 row affected (0.47 sec)

mysql> insert into DemoTable values('/111/118');
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 −

+--------------+
| Code         |
+--------------+
| /101/102/106 |
| /110/111/101 |
| /111/114/201 |
| /111/118     |
+--------------+
4 rows in set (0.00 sec)

Here is the query to get part of a string in based on a character −

mysql> select SUBSTRING_INDEX(SUBSTRING_INDEX(Code,'/',3),'/',-1) from DemoTable;

This will produce the following output −

+-----------------------------------------------------+
| SUBSTRING_INDEX(SUBSTRING_INDEX(Code,'/',3),'/',-1) |
+-----------------------------------------------------+
| 102                                                 |
| 111                                                 |
| 114                                                 |
| 118                                                 |
+-----------------------------------------------------+
