+-- Fix appointments table schema: Add start_time/end_time if missing
+-- This handles the case where init_db.php created the table with appointment_date instead of start_time
+
+-- Add start_time if it doesn't exist
+-- Note: MySQL/MariaDB < 10.2 don't support ADD COLUMN IF NOT EXISTS easily, so we use a stored procedure or just suppress errors in apply_migrations.php
+-- Assuming MariaDB 10.2+ or suppression in apply_migrations.php for "Duplicate column"

+ALTER TABLE appointments ADD COLUMN end_time DATETIME NULL;
+
+-- Migrate data if appointment_date exists
+-- Check if appointment_date exists first? SQL doesn't have conditional logic outside procedures easily.
+-- We'll try to update, if column doesn't exist it will fail but that's fine if start_time is already populated.
+-- Wait, if appointment_date doesn't exist, this query will fail and might stop migration script if not handled.
+-- But apply_migrations.php continues on error? No, it catches exceptions per statement.
+
+-- We can wrap in a procedure to be safe, but apply_migrations.php splits by ';'.
+-- So let's just try the update. If appointment_date doesn't exist, it fails harmlessly.
+
+UPDATE appointments SET start_time = appointment_date WHERE start_time IS NULL;
+UPDATE appointments SET end_time = DATE_ADD(start_time, INTERVAL 30 MINUTE) WHERE end_time IS NULL AND start_time IS NOT NULL;

+ALTER TABLE appointments MODIFY COLUMN start_time DATETIME NOT NULL;
+ALTER TABLE appointments MODIFY COLUMN end_time DATETIME NOT NULL;

+-- Drop appointment_date if it exists (optional cleanup)
