I need to import JSON data from an API to MySQL database using python. I can get the json data in python script but no idea how to insert this data to a mysql database.
finally, did it. Saved the JSON file locally first, then parsed it using key values in a for loop & lastly ran a query to insert into MySQL table.
Serializing JSON to string and insert string to DB, and make it Deserializing when you want to use it. I use this method but I don't know if it is optimum

After running the mongodb docker image I created a database called MovieFlix and some collections with items inside the database.
What I want is to find a way to store all the data from the MovieFlix db in a json file to have it saved for later user for docker-compose.
Should I do it with python code using pymongo or is there a simpler way ?
Mongodb has a command line tool for exporting to json or csv. The keyword for this is dump. Hope it helps!
I have a text field in a SQLite database table that stores JSON. I want my Python script to query all rows and stuff each JSON string into a single JSON object (or string, since I'm going to send it through a ReST API).
What is the best approach for doing so? Note there will be thousands of rows.
Thanks!
I am working on flask and mongodb. I am new to mongodb, I realized that mongodb do not let me insert json file to database, the file size is greater than 16mb
Is there any other database that is similar to mongodb (JSON object based) ?
Thank You
You can make use of PostgreSQL also for json kind of data to store, based on your Application requirements.
Please refer their official documentation for more information.
Hope the below links can be useful.

If we have a json format data file which stores all of our database data content, such as table name, row, and column, etc content, how can we use DB-API object to insert/update/delete data from json file into database, such as sqlite, mysql, etc. Or please share if you have better idea to handle it. People said it is good to save database data information into json format, which will be much convenient to work with database in python.
Thanks so much! Please give advise!
There's no magic way, you'll have to write a Python program to load your JSON data in a database. SQLAlchemy is a good tool to make it easier.
I know in javascript there is the stringify command, but is there something like this in python for pyramid applications? Right now I have a view callable that takes an uploaded stl file and parses it into a format as such. data= [[[x1,x2,x3],...],[[v1,v2,v3],...]] How can I convert this into a JSON string so that it can be stored in an SQLite database? Can I insert the javascript stringify command into my views.py file? Is there an easier way to do this?
You can use the json module to do this:
import json
data_str = json.dumps(data)
There are other array representations that can be stored in a database as well (see pickle).
However, if you're actually constructing a database, you should know that's it's considered a violation of basic database principles (first normal form) to store multiple data in a single value in a relational database. What you should do is decompose the array into rows (and possibly separate tables) and store a single value in each "cell". That will allow you to query and analyze the data using SQL.
If you're not trying to build an actual database (if the array is completely opaque to your application and you'll never want to search, sort, aggregate, or report by the values inside the array) you don't need to worry so much about normal form but you may also find that you don't need the overhead of an SQL database.
you also can use cjson, it is faster than json library.
import cjson
json_str = cjson.encode(your_string)
