![]() ![]() Use the following command to create a PostgreSQL table to use JSON data type with its field: CREATE TABLE product ( Use JSON Data Type in Table - How to Use JSON Operators in Postgres? - How to Use JSON Functions in Postgres? This post will demonstrate the following concepts regarding JSON functions and Operators: Postgres support various built-in functions and operators to fetch data using queries from JSON columns. JSON Functions and Operators in PostgreSQL This guide will explain the process of using JSON functions and operators in PostgreSQL. To query JSON data various operators and functions are utilized in Postgres. JSON is a type of data in PostgreSQL that is more useful and efficient in storing data in the PostgreSQL database.

To start we need to execute that code to create a table called test containing a single record, with a serial number in id and a JSONB payload in the json_data column. The cheatsheet includes a small JSON dataset (at the top left) that allows us to explore the functions. Otherwise, copy the Service URI, as highlighted, and use the tool of your choice. If the chosen tool is psql, we can get the necessary command line, complete with connection details, by clicking on Quick connect. Once the service status is Running we can use our favourite tool to connect. Let's go for pg-jsonb-cheatsheet so we can immediately understand why we created the PostgreSQL instance.Īfter clicking on Create service, we need just a couple minutes of patience for the service to come up. Service name: used to identify the service uniquely, we can either accept the default or write a more accurate name. ![]() For our testing purposes the Hobbyist plan would be enough. Service plan: various options are available, from hobbyist to premium plans, covering all the scenarios from test to highly available production system. ![]() Please note that you don't need to create a cloud account with the chosen provider, Aiven will handle everything for you.
