Keep a frequently used table easy to understand
A regular table reference can save time when you return to the same analytics question after a busy week.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
Why this helps
Returning to analytics after interruptions often means spending time rediscovering table columns and keys.
- Reduce repeated schema lookups.
- Make returning to a data task less effortful.
- Keep table details ready for recurring analysis.
Setup
Build it in a few focused steps.
- 1Connect ClickHouse to Notis once.
- 2Create an automation in the portal or ask Notis to create it in plain language.
- 3Write one instruction to retrieve detailed schema for the ClickHouse table used in your recurring analysis.
- 4Select a weekly cron trigger and choose a channel for reports.
- 5Test the run and confirm the returned table details match your needs.
Questions about this workflow
What details does the table schema include?
It can include column definitions, types, keys, and optionally sample data.
Can it cover a different table later?
Update the instruction to describe the table you want the recurring reference to cover.

Supported Triggers and Actions
Notis builds workflows that link Notion to ClickHouse. A trigger fires from one place; an action lands in another.
Notion triggers
ClickHouse actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Execute ClickHouse Query
Execute a sql query in clickhouse and return the results. this is the primary action for querying data from clickhouse databases.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Get Database Schema
Get comprehensive schema overview of an entire database including all tables and optionally their column definitions. essential for ai agents to understand the complete database structure in a single call.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Get Table Schema
Get detailed schema information for a specific table including column definitions, types, keys, and optionally sample data. this is essential for ai agents to understand table structure before constructing queries.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
List ClickHouse Databases
List all databases in the clickhouse instance. useful for discovering available databases before querying tables.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
List ClickHouse Tables
List tables in clickhouse databases. returns information about tables including their engine, size, and row count.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
