Understand a table before querying it
When you know the table to inspect, use a webhook to fetch its structure and make the next query easier to shape.
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
Writing SQL against unfamiliar columns creates avoidable backtracking and failed query attempts.
- Review column names and types before querying.
- Check keys and optional sample data when returned.
- Prepare a more informed follow-up query.
Setup
Build it in a few focused steps.
- 1Connect Anthropic administrator and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Tell Notis to retrieve the detailed schema for the ClickHouse table relevant to the requested Anthropic workspace analysis.
- 4Pick the notis_webhook trigger and choose where run reports go.
- 5Test with one real example and verify the requested table exists.
Questions about this workflow
Does the automation choose a table automatically?
The automation can use the table context supplied in your instruction or request. It cannot inspect an unspecified table through this action.
Does the lookup return sample records?
The action supports optional sample data, but availability depends on the request and the returned result.
