find number in json array value with regex - arrays

Question

i want match string in json string that like:
"ids":[44,53,1,3,12,45]
i want run query in sqlite send only one digit as id and match one of the above id in sql statement
i write this regex "ids":[\[] for matching start of key
but i don't have any idea to match middle id and escape starting id
example:
i have calc_method table like this:
CREATE TABLE "calc_method" (
"calc_method_id" INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT,
"calc_method_name" TEXT NOT NULL,
"calc_method_value" TEXT NOT NULL
);
in calc_method_value column i store calcMethod class which convert to json using Gson
class calcMethod{
var memberCafeIds:ArrayList<Long>,
var memberBarIds:ArrayList<Long>
}
after i convert calcMethod to json i have output like below and this value store in calc_method_value column:
{"memberCafeIds":[1,2,14,5,44],"memberBarIds":[23,1,5,78]}
now i want select row that match to my regex pattern like if calc_method_value column have memberBarIds with id 1
SELECT * FROM calc_method WHERE calc_method_value REGEXP '"memberCafeIds":\[[:paramId]'
:paramId is method parameter

In Sqlite, use JSON1 functions to work with JSON, not regular expressions. In particular, json_each() to turn the JSON array into a table you can query:
sqlite> CREATE TABLE ex(json);
sqlite> INSERT INTO ex VALUES ('{"ids":[44,53,1,3,12,45]}');
sqlite> SELECT * FROM ex WHERE 1 IN (SELECT value FROM json_each(ex.json, '$.ids'));
json
-------------------------
{"ids":[44,53,1,3,12,45]}
sqlite> SELECT * FROM ex WHERE 50 IN (SELECT value FROM json_each(ex.json, '$.ids'));
sqlite>
