If you've haven't installed the pup HTML parsing tool, or any other tool which required you to edit your ~/.bashrc's' PATH and create the ~/bin_compciv directory, then follow the instructions here: Installing programs for your personal Stanford account. You can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text. Jq is a program described as " sed for JSON data":

JSON stands for JavaScript Object Notation and is nearly ubiquitous as a data format, for its lightweight nature and (relatively) ease of human-readability.
#JSON QUERY TUTORIAL HOW TO#
Most of the popular API and data services use the JSON data format, so we'll learn how it's used to serialize interesting information, and how to use the jq to parse it at the command-line. jq is a command-line tool for parsing JSON. Here you will use JSON.JSON is a lightweight format that is nearly ubiquitous for data-exchange. Format the results of Transact-SQL queries in JSON format. Run any Transact-SQL query on the converted JSON objects. Transform arrays of JSON objects into table format. For existing keys, when the entire path exists, the value that it contains is replaced with the JSON value. By using SQL Server built-in functions and operators, you can do the following things with JSON text: Parse JSON text and read or modify values. For new Redis keys the path must be the root, so you will use “.” path in the example below. You will have to use the JSON.SET command to set the JSON value. Under RedisJSON, a key can contain any valid JSON value. Let’s go ahead and test drive some JSON-specific operations for setting and retrieving a Redis key with a JSON value: Before using RedisJSON, you should familiarize yourself with its commands and syntax as detailed in the documentation: RedisJSON Commands. To interact with RedisJSON, you will most often use the JSON.SET and JSON.GET commands. You can run them from the Redis command-line interface (redis-cli) or use the CLI available in RedisInsight. The following steps use some basic RedisJSON commands. Verify the database under RedisInsight dashboard Enter Redis Enterprise Cloud details Īdd the Redis Enterprise cloud database endpoint, port and password.

It makes it easy to discover cloud databases and configure connection details with a single click. It works with any cloud provider as long as you run it on a host with network access to your cloud-based Redis server. It is a fully-featured pure Desktop GUI client that provides capabilities to design, develop and optimize your Redis application. Query functions evaluate SQL/JSON path language expressions against JSON. RedisInsight is a visual tool that lets you do both GUI- and CLI-based interactions with your Redis database, and so much more when developing your Redis based application. Consider this document as a tutorial, the reference guide is available as a. You will be provided with Public endpoint URL and "Redis Stack" as the type of database with the list of modules that comes by default.
