Supabase RLS lets PostgreSQL enforce row-level access rules. Use policies with grants to control what anonymous and signed-in users can read or change.

Last updated

Syntax

CREATE POLICY policy_name ON table_name FOR { SELECT | INSERT | UPDATE | DELETE } TO role_name USING (condition) WITH CHECK (condition);
