These properties make JSON an ideal data-interchange language Notice how data-interchange appears twice? Personally I think traditional relational tables should be the default choice for data storage.

Taking JSON input and it storing as-is in your database should be the last resort. Or 32,767 bytes if you have enabled extended data types.And huge kudos to to Iudith for taking the top spot for the second year in a row!And, once again, a massive thanks to Elic, our quiz-reviewer supreme.In this post you'll learn how to: Store JSON in a database table Query a table for rows storing particular values within a JSON document Create indexes to find these rows efficiently Generate JSON from relational rows and columns Let's get started!How to Store JSON in Your Database JSON documents are just text.So to create a table that will store "large" JSON documents, run: create table departments_json ( department_id integer not null primary key, department_data blob not null ); Regardless of which data type you use, you'll want to verify that you're storing real JSON. To do this, add the IS JSON check constraint, like so: alter table departments_json add constraint dept_data_json check ( department_data is json ); Now you've got the table, it's time to start adding documents!
