Question

I am using visual studio 2008 with my database in sql server 2005.
I have created a chat online app. Once the user is online he/she can chat and his/her chat data will go in my message database which has this schema.

1. MessageID(pk)
2. RoomID
3. UserID
4. ToUserID
5. Text

After the chatter finishes chat he log’s out and
the messages sent by the “UserID” or say chat data in message table of that USerID must be deleted.

So
I want to delete multiple rows from the database at once.

Answer 1

Something like the following should help:

DELETE FROM [YOUR TABLENAME] WHERE UserId = [UserID]

Note: You can have a where clause in your delete statement using which you can specify the delete criteria.
