-- Verify that multiple bids are now allowed
-- Run this to check:

SHOW INDEX FROM `bids` WHERE Column_name IN ('inquiryId', 'supplierId');

-- You should see:
-- - idx_bids_inquiry_supplier with Non_unique = 1 (allows duplicates)
-- - NO index with Non_unique = 0 (no unique constraint)

-- Test: Try to insert two bids from the same supplier for the same inquiry
-- This should now work without errors!
