After creating a new database, I ran:
update user set password = 'SomeJunk' where user = 'root';
This inserts the string 'SomeJunk' literally into the database,

lockout (not to mention the security breach of having the clear
password stored in a file.
I got the smart idea to assign a root password like this from the
Bugzilla-Guide.txt file that comes with Bugzilla.
I just opened Bugzilla-Guide.txt and it says:
mysql UPDATE user SET Password=PASSWORD ('new_password') WHERE
user='root'; mysql FLUSH PRIVILEGES;
note the PASSWORD('new_password') instead of just 'new_password'
If there is a better way to assign passwords, please let me know.
I tried
grant all on mysql.* to foo identified by bar;
Seems to work for creating new accounts.
Try
GRANT ALL PRIVILEGES ON table.* TO user@localhost IDENTIFIED BY
'password';
Since in most cases (web server and mysql on same box) you don't need to
allow users to connect from anywhere. If you want to include a hostname or
wildcard, put it in '' (like '%.host.com' or just '%')
Also, the user table looks like:
mysql select host, user, password from user;
+---+-+--+
| host | user | password |
+---+-+--+
| localhost | root| 7d30d6e5796d165e |
| nomis | root| 7d30d6e5796d165e |
| localhost | | |
| nomis | | |
| localhost | ShimonR | 7d30d6e5796d165e |
+---+-+--+
5 rows in set (0.00 sec)
Does this mean that any user from localhost or from nomis can connect?
Don't know, but unless they have corresponding rows in another table to
actually give them privileges, they can't do anything.
I don't have rows like that in my user table so they should be safe to
delete.

Re: Shortest route between 2 cities
Here is the text of an email that I googled (eeek! its a verb!) The algorithm you need is called single-source, shortest path, also known as Dijkstra's algorithm. Here's one way to implement it, in pseudo-code. Shortest route on graph of locations in Inform -- For each location, we keep two properties: V (the visited flag) and C (initial step). We are given the values SOURCE (i.e., parent(NPC)) and DEST, the destination. N is a global variable. S and T are queues or stacks. 1. (Initialise) Let SOURCE.V = 1 and SOURCE.C = 0. Let N = 0 and S and T be empty. Push SOURCE onto S. 2. (Take one step) For each location I in S consider each possible location J which is reachable in one step from I and has J.V = 0 (i.e., hasn't been visited yet). Let J.V = 1. If N = 0, let J.C = J; otherwise J.C = I.C. If J = DEST, go to step 4. Otherwise, push J onto T. 3. (Repeat) If T is non-empty, let S = T, T be empty, N = N + 1 and go back to step 2. Otherwise, go to step 4. 4. (Done) If DEST.V = 0, then destination cannot be reached. Otherwise DEST.C is the initial step on the shortest path from SOURCE to DEST. N is the distance from SOURCE to DEST.

Re: mysql and php - Can't Connect To MySQL Server warning
Is it 'exactly' once every 10 times ??

innodb admin questions
My application needs to insert between 200-500k rows about once a day... When using MyISAM tables I determined the best way to get this done (while still allowing users to perform select statements from the table) was to use mysqlimport with --low-priority. This way all the inserts get bundled up into large groups, and the low-proriorty allows select statements to continue. However I switched the table type to Innodb now and I am not sure what the best way to insert these rows would be. There is: a) continue using mysqlimport (without low-priority??)... the question about this is will mysqlimport group the inserts into one large begin/commit block, or will each insert have its own block? b) create the begin/insert/commit statements myself What way would be the fastest and least abrasive on the server? Another question I have is reguarding memory usage... Will innobase use any of the key-buffer memory Mysql is using for MyISAM tables or is the only memory innobase uses defined with innodb_buffer_pool_size?

password('mypass') is a legal expression. It returns a non-empty string,
which probably evaluates to true. The statement is therefore equivalent

Hi Paul,
Sorry bout that. Yes it doesn't return any rows despite the fact that the
correct username and password are entered.
The user/pass was entered with the following query:
PHP4 $result = mysql_query(insert into user values ('$username',
password('$password'), '$email'));
The statement is therefore equivalent to:
select * from user where username='myname'
Oh. I'm trying to implement authentication. So I guess this is quite bad
:)
I'm still not sure why my original query (with passwd = ) isn't returning
any rows. Is there something wrong with the syntax?

Looks correct to me. Try running this query from the mysql program
to verify that you're really matching the password of some entry:
mysql SELECT *, password('mypass') FROM user;
Hi guys,
I've solved the problem, but it was something related to the password
function.
In my user table, my passwd field was only set to 12 characters. It appears
that password(blah), generates a password that is 16 characters long.
Since I was saving only the first 12 characters of the 16 char password, my
queury's passwd = password('blah') did not match.
What a bugger :)
