Help with SQL Query (Join)

Hi Experts,

I have two tables
1> Amenity
AmenityId (Int,PK)
Amenity (varchar(200)

2> HotelDetails
HotelId (int,PK)
HotelName (varchar(250)
AmenityId (varchar(200))


As you can see in hotelDetails amenity Ids are stored as CSV.
Like
2,4,7,8

Now I want to display Amenities of Hotels.
How to join these tables?

Ideally the Hotel Details table should have one row per amenity for an easy table join.

I think you can try something like this. Please excuse my concatantion syntax if I have it wrong for SQL Server

SELECT *
FROM HotelDetail H
          JOIN Amenity A
          ON ',' || H.AmenityID || ',' like '%,' || CAST(A.AmenityId as varchar(10)) || ',%'

Open in new window

Agreed but can't change the table definition.

The query given by you is not working in SQL server

Try this one. The || were invalid in SQL Server. I changed them to +

SELECT *
FROM HotelDetail H
          JOIN Amenity A
          ON ',' + H.AmenityID + ',' like '%,' + CAST(A.AmenityId as varchar(10)) + ',%'
