Why this helps
It is easy to lose time guessing which columns exist when campaign data lives in unfamiliar tables.
- See column names and types before writing a query.
- Use a table reference supplied in the request.
- Reduce trial and error when exploring unfamiliar analytics data.
Setup
Build it in a few focused steps.
- 1Connect ActiveTrail and ClickHouse once in the Notis portal.
- 2Create an automation from Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to retrieve the schema for the ClickHouse table named in the request and explain its columns.
- 4Choose a webhook trigger and the channel for run reports.
- 5Test with one real request that names an existing table.
Questions about this workflow
Can this inspect any table automatically?
It retrieves schema for the specific table named in the request. The table must exist and be accessible in the connected ClickHouse instance.
Does this start from an ActiveTrail event?
No. ActiveTrail has no listed trigger events. The automation starts when an external tool or custom backend sends a webhook request.
