May 04, 2026: CREATE OR ALTER SEMANTIC VIEW support (Preview)¶

You can now use CREATE OR ALTER SEMANTIC VIEW to create a semantic view if it doesn’t exist, or alter an existing semantic view to match the definition in the statement. This provides a declarative way to manage semantic view definitions that’s safe to re-run without having to replace the view and re-grant privileges.

CREATE OR ALTER SEMANTIC VIEW supports modifying tables, relationships, facts, dimensions, metrics, comments, AI instructions, and verified queries. Adding or changing tags isn’t supported. Existing tags are preserved.
