Snowflake createView

Last updated: March 26, 2026

Last updated: March 25, 2026

Creates a Snowflake view with optional row access policy for row-level security. Views are virtual tables that present query results as a table. The secure option hides the view definition from unauthorized users.

Note: Automatic rollback drops the view.

Known limitation: Snowflake snapshots created with Liquibase Secure 5.1 are incompatible with earlier versions due to enhanced object type detection for TABLES and VIEWS. Regenerate all snapshots with 5.1 after upgrading to avoid false differences in diff and diff-changelog operations.
