How to extract different json elements from the same table in SQL query?

Question

I am querying from a table with the following format:

id|provider|score
--------------------------------
1 |  att     | '{"attscore":300}'
1 |  verizon | '{"verizonscore":299}'
2 |   att    | '{"attscore":200}'
3 |  verizon | '{"verizonscore":155}'

I am trying to get a table that looks like the following:

id|attscore|verizonscore
-------------------------
1  |  300   |    299
2  |  200   |    null
3  |  null  |    155

Note that used to json in sql

Answer 1

 CREATE TABLE table1 ( `id` INTEGER, `provider` VARCHAR(7), `score` VARCHAR(22) ); INSERT INTO table1 (`id`, `provider`, `score`) VALUES ('1', 'att', '{"attscore":300}'), ('1', 'verizon', '{"verizonscore":299}'), ('2', 'att', '{"attscore":200}'), ('3', 'verizon', '{"verizonscore":155}');

 SELECT id, GROUP_CONCAT(CASE WHEN provider = 'att' THEN `score`->"$.attscore" ELSe NULL END) attscore,GROUP_CONCAT(CASE WHEN provider = 'verizon' THEN `score`->"$.verizonscore" ELSe NULL END) verizonscore FROM table1 GROUP BY id

 id | attscore | verizonscore -: |:------- |:----------- 1 |  300 |  299 2 |  200 |  null 3 |  null |  155

This works with a fixed number of column quite well, if you have much more of these you need to do something like this
