Check a table's structure before writing SQL
Get the details of one table when you have a device data question and need to know what the table can support.
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
A table name alone does not tell you which columns, types, or keys are available for a useful query.
- See detailed structure for a selected table.
- Review available types and keys before query planning.
- Use optional sample data when it is appropriate and available.
Setup
Build it in a few focused steps.
- 1Connect Adafruit IO and ClickHouse once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Ask Notis to retrieve the schema for a named ClickHouse database and table, including optional sample data if useful.
- 4Pick the webhook trigger, choose a report channel, and test with one real request.
