Overview

The query editor allows you to query blockchain data using DuneSQL.

Writing Queries

The Data Explorer allows you to search for blockchain and other data to use in your Queries. Here's how it works.

Finding Tables

Parameters allow you to implement variables in certain parts of your Query. This is useful if you want to create a Query that you can reuse with different parameters.

Using Parameters

Learn how to leverage the power of query scheduling for a more reliable and up-to-date dashboard display!

Scheduling Queries

Queries have a version history, where you can compare and revert to previous query versions.

Version History

Charts are good for condensing data points into a Visualization.

Create Graphs

Counters give you a way to display a single number prominently.

When and how do queries on Dune get executed?

Executions

The "Query View" feature in DuneSQL allows you to use an existing query as a view in another query. This powerful functionality enables you to create reusable queries, build complex queries, and take advantage of existing queries as views.

Query Views

Materialized tables are a way to store the results of a query in a table that can be queried like any other table. This is useful when you have a query that takes a long time to run, or when you want to use the results of a query in another query.
