I think the given idea is fantastic to store archived chats, or chats older than 1 year or so. One of the greatest advantages of an AJAX chat application is that it avoids the connectivity issues which are common with a range of other web app development technology.
The identifier column will have two usernames separated by a colon. I can keep typing and the Text area gets larger and large for each time I click enter… What could be possibly wrong? From past six month i am trying to make a chat room. Member 10514770 9-Jan-14 14:42 I have installed this and everything seems to work the way it should except users and their posts only show up on the same computer of the user and posts from users on other computers are not showing up in the chat other than the poster's computer.
About the Author - Can someone please help me. I thought of doing a start time and and end time.
EDIT People think this question is too broad so I'm narrowing things down a bit here: I have a table with dual primary keys: roomID and userID. Here is some example data: roomID userID 1 5 1 9 1 10 1 12 2 5 2 9 2 10 3 5 3 17 Given a list of users: 5,9,10, how can I return the roomID containing ONLY those users? So in this case it should return 2. I hope this can be done within 1 SQL query. Any help would be appreicated. ORIGINAL QUESTION I am making a chat room application and need to design a database backend for it. All the rooms are created on the fly and are destroyed when the last user exits the room. Users are able to add other users to any room they are in. Currently this is my design: I have a chatroom table with two columns. The two columns are both primary keys for the table so a row is considered duplicate only when both columns are the same. The first column is the room ID. The second column is a user ID. The idea I have here is with the same room ID, there can be many users in this room so rows with same room ID but different user ID. When I need to create a new room, I simply select MAX room ID + 1 and create a new room with this ID and add the users into it. Given a list of users IDs such as 1,5,31,12 , I need to find out if a room is already created for them. In other words, I need to determine if there are rows all with the same room ID having users IDs 1,5,31,12. However, if a room is created with users 1,5,31,12,6 one or more extra users , this should not count as room already created. I will then need to create a new room for them and add the users to that. Same goes for less users than the list. Right now I'm having trouble forming the query to determine if I need to create a new room or not, and if not, retrieve the room ID of the existing room. Any help would be appreciated. Also, I think this design is quite cumbersome, you are welcome to suggest a better database design.

I am still researching around the whole idea. I am really really happy today because with your difference i create my own chat room now i just want to make in this chat room a private massage command which people can chat each other and also do private chatting. Although I will say there is probably a lot more you could do having the data in a real database. La more manageable than using your own home-grown system. Maybe you can find real world architectures that deal with the same problems you may not be the first one chat room database design, and that have already been solved. I have developed the following database schema at the moment for managing users and solo history of users. And retrieving is very fast even if you have only one server with good configuration.
