Why this helps
A query built on assumed column names can waste time and produce unusable results.
- Inspect a table before query planning.
- Use actual column types and keys as query context.
- Reduce avoidable query retries.
Setup
Build it in a few focused steps.
- 1Connect Agiled and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis the goal in plain language.
- 3In one instruction, specify the database and table, then request schema details for query planning.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real request and check the returned table details.
Questions about this workflow
Does this run the query too?
No. This workflow retrieves the schema for a specific table. Use a separate query action to execute SQL.
What if I do not know the table name?
First use the table listing action to discover available tables, then run this schema lookup for the table you need.
