Re: MySQL Administrator Cron Errors
Hello. There are numerous bugs in MySQL Administrator (but mostly closed) where the key word is 'profile'. If necessary, you can access the source repository and build the latest available version, including the bugfix, yourself. More information about accessing the source trees is available at http://www.mysql.com/doc/en/Installing_source_tree.html Rich wrote: Hi folks. Downloaded the new Admin for OS X. I set a weekly cron and for some reason, it's emailing my terminal Mail app saying it couldn't load a profile. It's not the address I told it to send it to, and I don't quite get why it can't load a profile. Having just tried to back up my tables twice directly from the application, it crashed twice. Is this thing buggy?

Thanks, Jeff http://dev.mysql.com/doc/mysql/en/adding-users.html The security system wisely treats local users and remote users differently. For a truly secure server, someone must be physically at the machine in order to make a localhost login attempt. This presumes that some level of physical security also protects that machine. If an administrator had only one account, it wouldn't make a difference from where they logged in. That would be a hole in the security plan as you now have exposed admin rights beyond the server's physical security perimeter. Think about it in terms of James Bond or Mission Impossible. They wouldn't need to break into the vault containing the database computer if an administrative account could do what they wanted from outside, would they? With the two-tier system, an administrator could have limited privileges when not physically at the console and full privileges while at the console. Of course, logging in to the server through SSH, telnet, or some other remote terminal software defeats this kind of security check as the user now appears to be at the local terminal. Oh, well. It is not perfect but it is better than nothing at all! Shawn Green Database Administrator Unimin Corporation - Spruce Pine
automatic backups not working MySql Admin
I've downloaded the MySQL Admin 1.1 freeware tool to backup a mysql database. It works fine except that the timer doesn't work. When I set a time in the 'time' field, lets say 8:00, the backup never kicks off. Is this because this free software doesn't supply this functionality? Or could it be a bug? Is there another answer?

RE: Database user Permissions
Shawn, Thanks again for responding :o) All understood, it seems to me though that this is achieved when you create the user by specifying where the specific user can login from. So granting permissions to user@'%' means from anywhere while [EMAIL PROTECTED] means only when they access from that server. I guess that could be easily spoofed though. In any event, thanks for a thorough answer, at least I know the behavior is truly by design.

For a truly secure server, someone must be physically at the machine in order to make a localhost login attempt. This presumes that some level of physical security also protects that machine. If an administrator had only one account, it wouldn't make a difference from where they logged in. That would be a hole in the security plan as you now have exposed admin rights beyond the server's physical security perimeter. Think about it in terms of James Bond or Mission Impossible. They wouldn't need to break into the vault containing the database computer if an administrative account could do what they wanted from outside, would they? With the two-tier system, an administrator could have limited privileges when not physically at the console and full privileges while at the console. Of course, logging in to the server through SSH, telnet, or some other remote terminal software defeats this kind of security check as the user now appears to be at the local terminal. Oh, well. It is not perfect but it is better than nothing at all!

MySql and AOP?
Hi: I was visiting the Aspect Oriented Software Development (AOSD) -Europe Workshop 2005 website, (http://www.aosd-europe.net/workshop-web/discussions.html) especially the discusion area. There, I read the following: What is the state of application of AOSD especially in industry? The exact extent of where AOSD tools and techniques are used is difficult to evaluate, in particular, because of its hidden nature as an enabling technology in applications. There are not many open-source projects that clearly feature AOSD techniques, notable exceptions being MySQL and AJ Hotdraw. Furthermore, eight commercial IBM products currently include AOSD libraries. Is MySql implemented using AOSD technology? How they are related? I wasn´t aware of this.

How to use logrotate to manage binary logs
Hi all, This may be a simple solution that I'm just not seeing. logrotate has trouble with binlogs since the extension keeps changing, so instead of actually rotating logs out, I just get a dir filled with binlog.001.1 binlog.002.1 binlog.003.1 binlog.004.1 binlog.005.1 binlog.006.1 and on to inifinity. The manual says If you supply an extension in the log name (for example, |--log-bin=/|file_name.extension|/|), the extension is silently removed and ignored, so it appears I'm stuck. Does anyone have some pointer for me to set up auto-rotation?

Two solutions: 1) sort the rows to be inserted on the key 'email' before inserting. 2) Or: http://dev.mysql.com/doc/mysql/en/innodb-tuning.html If you have UNIQUE constraints on secondary keys, starting from MySQL 3.23.52 and 4.0.3, you can speed up table imports by temporarily turning off the uniqueness checks during the import session: SET UNIQUE_CHECKS=0; For big tables, this saves a lot of disk I/O because InnoDB can use its insert buffer to write secondary index records in a batch. But make sure you do not have any duplicates in the rows! After sending my mail, I discovered SET UNIQUE_CHECKS=0, and subsequent to that it also occurred to me to try putting the data in in sorted order. Unfortunately, doing UNIQUE_CHECKS=0 did not work, and even the combination of both did not work. First chunk (3.4m rows) was ~1.5 minutes, second was ~5 minutes... At this point I'm inclined to believe that there is something very wrong with the disk subsystem because of this and other problems (doing a large cp from the datapool filesystem to another filesystem brought the database to a near-halt, among other things). As a stop-gap solution, I created the table with no indexes, and loaded all the data (loaded in linear time), and plan on doing a CREATE UNIQUE INDEX on the table. Will this happen in linear time, or near-linear time? *sigh* -JF -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Downgrade privileges on connect
You are correct in that each mysql user account only has one set of permissions. Your application talks to the database and it may only need one login. One login = one set of permissions. When I am designing a web-based application, I always create at least two accounts. One will be read-only, the other read-write. All of the pages that do nothing but query the database (no inserts, updates, or deletes) use the read-only login. Those pages that must somehow affect the data use the other one. Neither of my application's mysql accounts will have full admin rights to the entire server. Each user authenticates with the application. It's your application that must downgrade the user's privileges to use the application's features. Your application will still need access to the data it gets from MySQL so changing your MySQL permissions doesn't make any sense, does it. It's your application that needs to say no to the user. You don't want MySQL saying no to your application. Do you?

What I'd like to be able to do is create one database user account for a database application with read and write privileges to the tables, but if an application user logs in who only has read access, then to downgrade the permission's on the SQL server for the database user to select only for that connection. I want to be able to give an added level of assurance that the user will not be able to write to the database even if the application controls are circumvented. As it is now, I have to create multiple database users and choose which one to connect to the database with based on the application users authorization level. So are you saying that you would rather have each user share a direct database login with other users (granting them certain common rights) or do you want each of your users to have their own separate database login? I really don't think you want either. As you describe it, your application is in charge of authenticating each user (not the database). That means that each user only gets the privileges that the application lets them have. If your application's security structure is not set up to deny privileges based on their login, then your application is poorly designed. Your application's users should not have ANY direct access to the database on the backend unless you give them a database login to connect with AND they have the ability to connect directly to the database. The account your users use to connect to your application should not be a mysql user account. That should be something setup as a separate table in a separate database. Having at least two logins for each application is a wise precaution. One login can have read-only privileges while the other can have read-write privileges. Those would be mysql logins. The users should not have access to that information. Your security model should look something vaguely like this: ||| ||| database ||| application ||| user server ||| ||| ^^ mysql login application login That way the user never talks directly to the database. All user interaction with data is filtered and controlled by the application. The user should only have the ability to do things in the application that the user has been given privileges to do. It's the application's responsibility to act like a firewall between the user and the database. Now, don't do something dumb and put mysql logins and passwords as plain text into an application that you install on the user's system. It is SO easy to read through a compiled file and get all of the plain-text strings and try them out. What would be better is if your user's never even had access to the code that talks to the database (not even as a file on their system). Please write back if any part of this

Re: Downgrade privileges on connect
[EMAIL PROTECTED] wrote on 10/12/2005 10:46:46 AM: You are correct in that each mysql user account only has one set of permissions. Your application talks to the database and it may only need one login. One login = one set of permissions. When I am designing a web-based application, I always create at least two accounts. One will be read-only, the other read-write. All of the pages that do nothing but query the database (no inserts, updates, or deletes) use the read-only login. Those pages that must somehow affect the data use the other one. Neither of my application's mysql accounts will have full admin rights to the entire server. Yes, and that is how the application is coded, as that has always been the only way to do it. Each user authenticates with the application. It's your application that must downgrade the user's privileges to use the application's features. Your application will still need access to the data it gets from MySQL so changing your MySQL permissions doesn't make any sense, does it. It's your application that needs to say no to the user. You don't want MySQL saying no to your application. Do you? Again, my concern is not normal operations, but the 'what if a user fuzzes the data in a way that is completely new and unexpected in an attempt to circumvent the controls of the application?' For example, I have a database table editor, with some users having read access to see the data, and some users having write access to add, modify and delete the data. They use the same application, but users who are not allowed to write do not get access to those functions, and the server code verifies that a user has write access again before actually making any changes in case of a modified post query, or other malicious activity. It should be bulletproof, but I believe in security in depth and so for read-only users I connect to the database with a SQL user that only has the select privilege, and for read/write users I connect to the database with a user with select,insert,update,delete privileges. This all works fine, the only reason to change it would be to reduce the number of SQL users an application requires. Then I could create one user with select,insert,update,delete, for example, but when the connection is established a SQL command could be issued requesting a downgrade of privileges to select only. It all comes down to having fewer application passwords to change on a regular basis to stay current with security requirements. I realize that there is probably no way to do that with the current MySQL API, but perhaps it could be a feature request for future releases.

James,
Both ...
SELECT ...
FROM a, b LEFT JOIN c ON a.x=c.y
and
SELECT ...
FROM a
LEFT JOIN B USING (x )
LEFT JOIN c ON a.x=c.y
work up to and including version 5.0.10, not in 5.0.11, 12 or 13.
http://bugs.mysql.com/bug.php?id=13832 reports...
"The two statements below are quite different from one another:
1) SELECT * FROM t1, t2 LEFT JOIN t3 ON t1.a=t3.c
2) SELECT * FROM t1 JOIN t2 LEFT JOIN t3 ON t1.a=t3.c
"Statement (1) above will likely continue to give an "Unknown column
't1.a' in
'on clause'" error, while statement (2) will likely function correctly
at some
point in the future.
"This bug report is in reference to statements like statement (2), and
no bug
reports that use a statement like statement (1) are duplicates of this
bug."
The behaviour of (1) above is also verified
(http://bugs.mysql.com/bug.php?id=13551), and that page explains...
"This is a change that was made in 5.0.15 [sic] to make MySQL more
compliant with the standard. According to the SQL:2003
from clause ::= FROM table reference list
table reference list ::=
table reference [ { comma table reference }... ]
table reference ::=
table factor
| joined table
joined table ::=
cross join
| qualified join
| natural join
...
"Thus when you write
... FROM t1 , t2 LEFT JOIN t3 ON (expr)
it is parsed as
(1) ... FROM t1 , (t2 LEFT JOIN t3 ON (expr))
and not as
(2) ... FROM (t1 , t2) LEFT JOIN t3 ON (expr)
so, from expr you can only refer to columns of t2 and t3 - operands of
the join. Workaround - to put parentheses explicitly as in (2). Then
you can refer to t1 columns from expr.
Unfortunately, this change is not properly documented in the manual, it
will be fixed."
