DatabaseInfo.UserNames limited to about 1024 bytes?

Post by upscene » Fri 28 Oct 2011 12:20


I noticed that when trying to get the users connected to a database, there's a maximum number of users I get returned, a customer reported 63 at first, but I've seen 168 and 65 as well.

Closer inspection of this issue revealed the maximum number of usernames seems to be related to the resulting string size, somewhere up to 1024 bytes.

Is this a known problem? Can this be fixed at the client side or is this a Firebird issue?

With regards,
