-- ============================================
-- SOLUTION: Recreate Foreign Keys with New Names
-- This allows us to drop the old ones
-- ============================================

-- STEP 1: Try to drop foreign keys with common names
-- Run these one by one (some will fail, that's fine):
ALTER TABLE `bids` DROP FOREIGN KEY `bids_ibfk_1`;
ALTER TABLE `bids` DROP FOREIGN KEY `bids_ibfk_2`;
ALTER TABLE `bids` DROP FOREIGN KEY `bids_inquiryId_fk`;
ALTER TABLE `bids` DROP FOREIGN KEY `bids_supplierId_fk`;

-- STEP 2: Now try dropping the unique index
ALTER TABLE `bids` DROP INDEX `bids_inquiry_id_supplier_id`;

-- STEP 3: Recreate foreign keys with explicit names
ALTER TABLE `bids` 
  ADD CONSTRAINT `bids_inquiryId_fk` FOREIGN KEY (`inquiryId`) REFERENCES `inquiries` (`id`) ON DELETE CASCADE;

ALTER TABLE `bids` 
  ADD CONSTRAINT `bids_supplierId_fk` FOREIGN KEY (`supplierId`) REFERENCES `suppliers` (`id`) ON DELETE CASCADE;

-- STEP 4: Create non-unique index
CREATE INDEX `idx_bids_inquiry_supplier` ON `bids` (`inquiryId`, `supplierId`);

-- STEP 5: Verify
SHOW INDEX FROM `bids` WHERE Column_name IN ('inquiryId', 'supplierId`);
