Parameterized queries allow you to create reusable SQL templates with configurable values. Instead of writing multiple similar queries, you can define parameters that can be changed each time you run the query.

​
How to Use Parameters

Replace any value in your query with {{param_name}} to create a parameter. The query editor will automatically detect these parameters and provide input fields for them.
1

Write a Query with Parameters

Use double curly braces to define parameters in your SQL query:
-- DEX USD volume for a configurable chain and time period
select
  date(block_timestamp) as date,
  chain,
  sum(usd_amount) as usd_volume
from crosschain.dex.trades
where
  block_timestamp >= current_timestamp - interval '{{last_n_days}} days'
  and chain = '{{chain}}'
group by all
order by date asc;

Set Parameter Values

The query editor automatically detects parameters and displays input fields. Enter your desired values:
  • last_n_days: 3
  • chain: solana

Run and Iterate

Click Run to execute the query with your parameter values. You can modify the parameters and re-run the query to analyze different chains, time periods, or other variables without rewriting the SQL.

Advanced Parameter Techniques

Parameters become even more powerful when using the Explorer API to run queries programmatically. You can dynamically set parameter values in your API requests to create flexible data pipelines and applications.This enables:
  • Automated data pulls with variable filters
  • User-driven dashboards and reports
  • Dynamic data exports based on business logic
