Question : Slash between values question

Hello experts!

I have 10 columns in my database called table_nightclub_1, table_nightclub_2, table_nightclub_3, table_nightclub_4 and so on. Datatype = enum('Y', 'N', '').

Y if the table is booked - N if not.

How can I echo '1 / 2 / 3' if table 1, 2 and 3 are booked? And only '1' if table 1 is booked? '8 / 9' if table 8 and 9 are booked.

I can't find a smart way to make a slash between the values:-/ Hope someone can help me!

Thanks in advance!
