How does Looker Work?

Looker is basically used for creating SQL queries and then passing them into the database connection. Hence, looker produces the SQL queries which are based on the project called LookML, describing the relationship between the tables and their columns present in the database. Let us understand the working of the looker in the section below:

1. Viewing the query:

A user can simply use the SQL tab present in the Looker’s data section and know what all is Looker sending into the database for getting the data. The user can even use the bottom links for viewing the query present in the SQL runner.
Let us refer to the image below for a better understanding:

2. The canonical form of a Looker Query:

The dimensions, views, measures, explores and references, etc are all defined in the LookML project. Let us refer to the image below:

3. Running raw SQL in Looker’s SQL Runner:

The Looker consists of a feature called SQL runner that helps in running the SQL against DB connections the user has set up inside the Looker. The raw queries present in the SQL are executed in the SQL Runner producing an identical outcome. The SQL runner also helps in highlighting the errors present in the SQL command along with the position of the error in the message in case the SQL gets any kind of errors.

Looker Blocks

The looker blocks are defined as the pre-built pre-built models of data that are used for accelerating the sources of data and their analytics patterns. These are also called the entry points used for flexible, easy, and quick analytics. 

Let us have a look at a few looker blocks and discuss their usage:

Source Blocks: These are the data sources for the analytics, working as a third party. 
Analytic Blocks: Helps in various types of analysis of the design patterns
Data Tools: They have multiple data analytic techniques.
Data Blocks: They have public data which is pre-modeled.
Viz Blocks: Represents the output of the query of the type custom visualization
