+-- Add user_id columns to existing tables
+-- Since we're adding NOT NULL columns to potentially existing data,
+-- we need to handle this carefully
+
+-- First, add the columns as nullable
+ALTER TABLE `categories` ADD `user_id` text REFERENCES user(id);
+ALTER TABLE `todos` ADD `user_id` text REFERENCES user(id);
+
+-- Note: In a production environment, you would need to:
+-- 1. Populate these columns with appropriate user IDs for existing data
+-- 2. Then make them NOT NULL in a separate migration
+-- For development, you might want to clear existing data or assign a default user
+
+-- For now, we'll leave them nullable and handle the constraint in application code
+-- until existing data is properly migrated
