Getting last value in MySQL group concat?
To get last value in group concat, use SUBSTRING_INDEX(). Let us first create a table −
mysql> create table DemoTable1525 -> ( -> ListOfSubjects text -> ); Query OK, 0 rows affected (1.13 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1525 values('MongoDB,C');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1525 values('Java,C++,MySQL');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable1525 values('Python,C++,C,Java');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1525;
This will produce the following output −
+-------------------+ | ListOfSubjects | +-------------------+ | MongoDB,C | | Java,C++,MySQL | | Python,C++,C,Java | +-------------------+ 3 rows in set (0.00 sec)
Here is the query to get last value in group_concat() −
mysql> select substring_index(ListOfSubjects,',',-1) as LastValue from DemoTable1525;
This will produce the following output −
+-----------+ | LastValue | +-----------+ | C | | MySQL | | Java | +-----------+ 3 rows in set (0.00 sec)
