Based on the provided solution, I will rewrite it in a more readable format with added comments and explanations. Solution The solution is similar to your earlier Check Hall Booking status question. We need to find any matches of your input against the booking information. Not directly from the Bookings table but the exploded, taking into consideration of the combinedIds. We have three unions to cover the following scenarios: Direct bookings without combined halls.
