MySQL query to fetch specific records matched from an array (comma separated values)
To fetch records from comma separated values, use MySQL FIND_IN_SET(). Let us first create a table −
mysql> create table DemoTable1548 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20), -> ArrayListOfMarks varchar(100) -> ); Query OK, 0 rows affected (0.88 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1548(StudentName,ArrayListOfMarks) values('Chris','56,78,90,87');
Query OK, 1 row affected (0.29 sec)
mysql> insert into DemoTable1548(StudentName,ArrayListOfMarks) values('Bob','90,78,65');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1548(StudentName,ArrayListOfMarks) values('David','91,34,56,78,87');
Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1548;
This will produce the following output −
+-----------+-------------+------------------+ | StudentId | StudentName | ArrayListOfMarks | +-----------+-------------+------------------+ | 1 | Chris | 56,78,90,87 | | 2 | Bob | 90,78,65 | | 3 | David | 91,34,56,78,87 | +-----------+-------------+------------------+ 3 rows in set (0.00 sec)
Here is the query to fetch specific records matching from comma separated values −
mysql> select * from DemoTable1548 where find_in_set('87',ArrayListOfMarks);
This will produce the following output −
+-----------+-------------+------------------+ | StudentId | StudentName | ArrayListOfMarks | +-----------+-------------+------------------+ | 1 | Chris | 56,78,90,87 | | 3 | David | 91,34,56,78,87 | +-----------+-------------+------------------+ 2 rows in set (0.00 sec)
