I'm trying to understand the terminology a bit.
A left or right join can only exist for an outer join. For an inner
join, the terminology would be out of context because inner joins are
symmetrical (whereas outer joins are asymmetrical).
Would this be a correct understanding? Anything to add
Hi,
Okay, ill remove the extra log then.
The problem isnt that the socket doesn't get created, its that it randomly
disappears when mysql has been running for weeks already. So, /tmp's
permissions are correct, and everything works for a undecided amount of
time, then it just disappears and mysql
I have just installed MySQL 5. The server is running, but I'm not able to
connect to the server as root.
I have not set any root password, since I have not found any way to do this in
version 5 (it was rather good documented in version 4).
I have tried this solution to set the root password,

That sounds like the technical answer. I prefer an analogy a 5th
grader could understand. If you have 2 overlapping circles, and inner
join is the area that overlaps. A left/outer join is the all of the
left circle plus the content of the right circle that overlaps. A
right/outer join is
Somewhat tangential, but for whatever it is worth I agree with the
view expressed at
http://weblogs.sqlteam.com/jeffs/archive/2008/02/13/on-right-outer-joins.aspx:
Right joins should be avoided (IMHO).
Anything to add or correct, please?

I have a directed graph (nodes and edges) that I want to store
efficiently: given two nodes, I want to quickly find the shortest
path between them. The graph is NOT acyclic (it's not a tree), is
fairly sparse (about 1 edges for 2500 nodes), and changes
occasionally.

Kelly,
I'm not married to using SQL: are there other efficient solutions to
store directed graphs? Could I hack something up in Perl or Ruby and
then serialize my in-memory graph to a file (for efficient
saving/reloading)?
Did you look at Dijkstra's algorithm?

In my PHP environment, I have Magic Quotes turned off, and I use the
mysql_real_escape_string() function clean strings of SQL syntax before
inserting them into my database.
So the data stored in my database does not have escape characters in it.
