Is there any way to use values from a JSON object in a MySQL Select statement?\n
Yes, you can use json_extract(). Let us first create a table −
mysql> create table DemoTable -> ( -> Data json -> ); Query OK, 0 rows affected (0.63 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('{"Name": "John", "CountryName": "US"}'); Query OK, 1 row affected (0.33 sec) mysql> insert into DemoTable values('{"Name": "Chris", "CountryName": "UK"}'); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+----------------------------------------+ | Data | +----------------------------------------+ | {"Name": "John", "CountryName": "US"} | | {"Name": "Chris", "CountryName": "UK"} | +----------------------------------------+ 2 rows in set (0.01 sec)
Following is the query to use values from a JSON object in a MySQL Select statement −
mysql> SELECT *from DemoTable WHERE json_extract(Data, '$.CountryName') like '%US%';
Output
+---------------------------------------+ | Data | +---------------------------------------+ | {"Name": "John", "CountryName": "US"} | +---------------------------------------+ 1 row in set (0.00 sec)
