Check a ClickHouse table before querying campaign data
Know what a table contains before building a query, with its available columns and types summarized in plain language.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Table Schema
Gets the schema and column details for a table.
Why this helps
Guessing column names or data types can slow down campaign analysis and produce queries that need repeated correction.
- Inspect a specific table before constructing a SQL query.
- Summarize column definitions, types, keys, and sample data when available.
- Avoid assumptions by surfacing missing database or table details.
Setup
Build it in a few focused steps.
- 1Connect Abyssale and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to retrieve the schema for the database and table named in each request and summarize the structure.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real database and table name and review the returned schema details.
Questions about this workflow
What details should be in the request?
Provide the ClickHouse database and table names, plus the question the schema needs to support.
Does this action execute SQL?
No. It retrieves table schema information. Use Execute ClickHouse Query for a SQL query.
Are sample rows always included?
Sample data is optional in the action description, so availability depends on how the action is invoked and what it returns.
