-- Get the exact foreign key names from the CREATE TABLE statement
-- Run this:

SHOW CREATE TABLE `bids`;

-- Look in the output for lines that say:
-- CONSTRAINT `something` FOREIGN KEY (`inquiryId`) REFERENCES `inquiries` (`id`)
-- CONSTRAINT `something` FOREIGN KEY (`supplierId`) REFERENCES `suppliers` (`id`)

-- The `something` is the constraint name you need to drop
-- Copy those constraint names and use them in the DROP FOREIGN KEY commands
