Data sharing with dynamic tables

Dynamic tables are shareable objects. To share a dynamic table, data sharing providers grant privileges on a dynamic table to a share, which in turn can be used by data sharing consumers.

How data is shared with dynamic tables

To share a dynamic table with other Snowflake accounts, you can add dynamic tables to a share or to an application package.

  • To share a dynamic table with accounts in your region, you can use a Direct Share. For more information, see Data sharing and collaboration in Snowflake.
  • To share a dynamic table with accounts in other regions, add the share or application package to a listing as a data product and set up Cross-Cloud Auto-Fulfillment. For more information, see Create and publish a listing.

A data sharing provider can choose to grant the SELECT privilege on a single dynamic table or grant the SELECT privilege on all dynamic tables in a database, as shown in the following examples.

GRANT SELECT ON ALL DYNAMIC TABLES IN SCHEMA mydb.public TO SHARE share1;

GRANT SELECT ON DYNAMIC TABLE mydb.public TO SHARE share1;

For more details, see GRANT <privilege> … TO SHARE.

Create a dynamic table to ingest shared data

When you use a dynamic table to ingest shared data, the query can’t select from a shared dynamic table or a shared secure view that references an upstream dynamic table.

To create a dynamic table to ingest shared data, do the following:

  1. Ensure that you have the right privileges, and create a database from a share and grant privileges on it.

    CREATE DATABASE my_shared_db FROM SHARE provider_account.share1;

  2. Grant privileges to the shared database.

  3. Create a shared dynamic table.

CREATE OR REPLACE DYNAMIC TABLE my_dynamic_table
  TARGET_LAG = '1 day'
  WAREHOUSE = mywh
  AS
    SELECT * FROM my_shared_db.public.mydb;

Note

Change tracking must be enabled on all underlying objects used by a dynamic table. To use a dynamic table to ingest shared data, the data sharing provider needs to enable change_tracking on the shared object. For more information, see Enable change tracking.
