I'm working on a iOS application and I use Flask(a Python framework) to build my backend.
I store my data in
I don't quiet know the situation you meet , But it's not recommended to store multi records in one column , It's more normalised to build a relation map between
ID owner and
For example , you can create a new table called 'IDs' with schema like that :
id int auto increment , idbla varchar(<Your ID Length>) owner int not null
When you are trying to get all
idbla of some user
x you can use
SELECT * idbla from IDs where owner = x
You can use
nosql (non relational database) to store your data , It's document like and fit your situation pretty well .
