Hi there.
I've been having this problem when retrieving rows from a table
using mysql_fetch_row(). The problem is that sometimes it returns
null when I know that there are more records available. The behaviour
is intermittent too so its really difficult to track down.
I've tried it with MySQL

Hello.
Are you sure that mysqld uses /etc/mysql/my.cnf? See:
http://dev.mysql.com/doc/mysql/en/option-files.html
I suggest you to use official binaries and perform installation
according to the following:

Hello.
Not enough information to make a conclusion. What version of
MySQL do you use? Usually debugging of replication problems
begins from researching of binary logs with mysqlbinlog. See:

Hello.
You should solve the issue with server crashes. I'm not familiar with JDBC,

with JDBC, probably somebody clever on the list could help you. You may

are grouping on history.person_id, so it makes no sense to select any

Indeed, other systems wouldn't even allow selecting non-grouped columns

implement at the application code level. Basically whenever you insert

Hi,
i think you must normalize your table to more than one table.
Users/Groups : N:1
Groups/Groups : N:1
Table Users :
User_id
Host
Group_id
Table Groups :
Group_id
Group_parent_id- is a another group_id
No data redondancy and robust implementation.
see for example /etc/passwd and
IF GroupID, HostID and UserID are unique between the three sets then your
GroupMember table will work although I would still be tempted to add a
MemberType in the GroupMember table.
Isn't MemberID the Foreign Key to UserID/HostID/GroupID althugh I don't know
