Is it possible to add a set of elements in one cell with MySQL?

To add a set of elements in a single cell, use the concept of JSON. Let us first create a table −

mysql> create table DemoTable1828      (      EmployeeId int,      EmployeeRecords JSON      ); Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1828 values(1,'[{"EmployeeName":"Chris","EmployeeAge":29},{"EmployeeName":"David","EmployeeAge":27}]'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1828 values(2,'[{"EmployeeName":"John","EmployeeAge":36},{"EmployeeName":"Mike","EmployeeAge":32}]'); Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1828; 

This will produce the following output −

+------------+----------------------------------------------------------------------------------------------+ | EmployeeId | EmployeeRecords                                                                              | +------------+----------------------------------------------------------------------------------------------+ |          1 | [{"EmployeeAge": 29, "EmployeeName": "Chris"}, {"EmployeeAge": 27, "EmployeeName": "David"}] | |          2 | [{"EmployeeAge": 36, "EmployeeName": "John"}, {"EmployeeAge": 32, "EmployeeName": "Mike"}]   | +------------+----------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)
