JSON_TABLE processing

[DK Singh]

SET @json_data = '{"PhCity":["Houston","Brooklyn","New york","Memphis","Hytxsville"]}';

SET @phcity_list = (
SELECT GROUP_CONCAT(CONCAT("'", value, "'"))
FROM JSON_TABLE(@json_data, '$.PhCity[*]' COLUMNS (value TEXT PATH '$')) AS jt
);
select @phcity_list;

this is my json and want to get @phcity_list output in 'Houston','Brooklyn','Memphis' so that I can use it in my query like 'select * from MyTable where City in(@phcity_list ) limit 100'. But currently select @phcity_list; returns me result like '\'HOUSTON\',\'FAR ROCKAWAY\',\'WAUSAU\',\'KINGSTREE\',\'ORANGE CITY\'' so, due to '\' no result(s) able to get. Looking a genuine solution for the same. Can't use table variable because it gives error that table variable can't be reopen. There are several uses of this json in a single stored procedure
