+-- Allow NULL titles in notes table
+-- SQLite doesn't support ALTER COLUMN, so we need to recreate the table
+
+-- Step 1: Create new table with nullable title
+CREATE TABLE notes_new (
+    id TEXT PRIMARY KEY NOT NULL,
+    user_id TEXT NOT NULL REFERENCES users(id) ON DELETE CASCADE,
+    title TEXT,  -- Now nullable
+    content TEXT NOT NULL DEFAULT '',

+    is_pinned INTEGER NOT NULL DEFAULT 0,
+    is_archived INTEGER NOT NULL DEFAULT 0,
+    created_at TEXT NOT NULL DEFAULT (datetime('now')),
+    updated_at TEXT NOT NULL DEFAULT (datetime('now'))
+);
+
+-- Step 2: Copy data from old table
+INSERT INTO notes_new (id, user_id, title, content, color, is_pinned, is_archived, created_at, updated_at)
+SELECT id, user_id, title, content, color, is_pinned, is_archived, created_at, updated_at FROM notes;
+
+-- Step 3: Drop old table
+DROP TABLE notes;
+
+-- Step 4: Rename new table
+ALTER TABLE notes_new RENAME TO notes;
+
+-- Step 5: Recreate indexes
+CREATE INDEX idx_notes_user_id ON notes(user_id);
+CREATE INDEX idx_notes_is_pinned ON notes(is_pinned);
+CREATE INDEX idx_notes_is_archived ON notes(is_archived);
+CREATE INDEX idx_notes_updated_at ON notes(updated_at);
