web data entry problem
I hope someone might be willing to help out. I'm trying [still] to learn MySQL and php - to create some simply web based database. I have installed quite a few php/MySQL web database apps from books, however, none of them will get data entered into my database. When I create the database exactly as instructed, everything works great, but when I create the form to send/add a new record to my db then look at the db the new data is not there. This happens repeatedly with every example I build. I can add records using a terminal or phpMyAdmin. I'm running MySQL 4.0.14, Mac OS X 10.3, PHP 4.3.2. I installed 'tasks' - http://www.versiontracker.com/dyn/moreinfo/macosx/17996 and it works just fine! but it is too big for me to use to compare to my very simple scripts. Here is one I have recently installed whose data will not enter: http://hotwired.lycos.com/webmonkey/99/21/index3a_page4.html? tw=programming I believe my db connection is being made (I may be wrong), after all my phpMyAdmin app also works fine. I would be very grateful is there might be a kind soul who would work with me to help me to find out what is wrong? I have had dbs before that worked fine, I don't understand this problem at all.

I need to drop the rows returned that have the same part_description field,
like the DISTINCT clause does for rows, i need the same thing for a field

If I've got you right you need:
SELECT .. GROUP BY part_description

Access rules for users from specific hosts
Hi there, I'm seeing some problems with the way I've granted access to different users. I've setup the server to allow access only from certain clients. For example, the backup user is only allowed access from some machines: GRANT SELECT ON testdb.* TO [EMAIL PROTECTED] The problem is that when connecting I must supply a -h option to match the grant e.g. [EMAIL PROTECTED] mm1]$ mysql -u backup ERROR 1045: Access denied for user: '[EMAIL PROTECTED]' (Using password: NO) [EMAIL PROTECTED] mm1]$ mysql -u backup -h 127.0.0.1 Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 32 to server version: 4.0.15-standard-log Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql Is there an option to get the MySQL server to resolve localhost to 127.0.0.1 automatically? Or do I just have to use the -h option everywhere? It's not a big problem for me, but somewhat of an annoyance :( Many Thanks, Mike -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Is your MySQL server on the same machine as the WWW server? I assume that you have included your MySQL username/password in your PHP script, but do the access rights on the MySQL server allow access for your MySQL account from the WWW server?

Column Definition Column?
Does MySQL have a description column avialable for columns within table definitions? What I mean is when you do and explain TABLE_NAME can you get a column that as a description for each field? This would of course be especially useful for documentation purposes. Thanks for your help. Chris Streeter Bethlehem, PA, USA

Big difference in MyISAM and InnoDB SELECT speed
Hello, I am trying to optimize MySQL (3.23.49 from Debian stable) setup for ASPseek application. I decided to try InnoDB in order to be able to update tables while performing time consuming selects.

RE: Error 1045: Acess denied for user: 'ODBC@localhost' (Using password: YES)
ike, Well, there are quite a few wierdnessess that I have experienced. One, for instance, is if you are working in the GUI editor interface, and are mucking around with the User priveleges I have actually had the GUI wipe the passwords to null for all rows. I'm sure its just because I'm not aware of the assumptions being made by the Control Center. Something like, I will change everything with the prefix XYZ when you press this button. Anyway, I probably created a new user for a specific database or something for my standard user login (but for a different machine host maybe) ( I use explicit definitions for all hosts.) And forgot to put in the password and that updated ALL the passwords for that login in the User table...on ALL hosts?... which rapidly halted all working applications. So I suggest logging into you mySQL server as root, and look at the user table and the user privileges, use a specific SQL request, otherwise you'll get an unreadable table in the Command Prompt viewer. (Don't forget to set the database to the master mysql database.) Select Host, User, Password from User ( The conclusion is that I believe you have all the passwords for your given login will be ) Use the Update User set Password = PASSWORD(mypasshere) where User = someone; Don't forget to FLUSH PRIVILEGES; when you're done mucking around, or none of you changes will take effect and you will quietly go crazy and or bald.

Janusz, Now the question is: how should I set up (and maintain?) my MySQL server to prevent it from using indexes inefficiently? Quite a good question, no idea. But if the query select url_id from urlword where deleted=?? and status=??? and origin=?; is a query that you will use very often, I still think that creating an index on (origin,status,deleted) is the good answer.

Re: Inefficient use of index (was: Big difference in MyISAM and InnoDB SELECT speed)
Hi, You are not using any indicies, because there aren't any that could be used in this query. Try adding an index on (status,deleted) I wonder: how many possible different values would such an index return? If this is a (very) low value, won't the index make things slower (if it's being used) compared to a full table scan?

Re: Inquery from Varian Medical Systems
Hi Robert, I did not see any suggestions to you. So here is one. If you want a guarantee simple brute force dump the entire DB with mysqldump and recreate of the slave. For Exmaple mysqldump --opt mydb | mysql -umyuser -pmypwd -hremotehost myremotedb You can run this through an ssh tunnel for security or compress and forward or do it in multiple steps. But if it completes without errors all data will be present on the remote system.

Re: web data entry problem
There could be a number of things going on. It would help troubleshoot your problem if your script check for errors and print them if there are any.

Re: Help recovering db
From MySQL Manual: If you want to change the number or the size of your InnoDB log files, you have to shut down MySQL and make sure that it shuts down without errors. Then copy the old log files into a safe place just in case something went wrong in the shutdown and you will need them to recover the database. Delete then the old log files from the log file directory, edit `my.cnf', and start MySQL again. InnoDB will tell you at the startup that it is creating new log files. I hope it can help you.

When you do a mysqld -? it will say: Default options are read from the following files in the given order: /etc/my.cnf /var/lib/mysql/my.cnf~/.my.cnf So that's the reason you can not start it anymore.

protect data integrity??
Hello, mysql Gurus, I am wondering if there is any data integrity protection can be done if I allow uses to update database from mysql Control Center or Excel and any other applications that is connected to mysql thru mysql ODBC. I need to reject the action if it makes violation of the data integrity (like sth not in enum values, or some relations between tables that foreign key constraint can't protect). At this moment I have a script that takes a sql command file that intends to update the database, checks each command to see if the result of executing it would violate data integrity. The script is executed at command line. But if the update comes from windows applications, I am not sure how I can get my script working in between mysql server/client and the application. Has anyone been in the same situation as I am? Any suggestion would be very welcome. The version of mysql is 4.0.16 running on Linux redhat.

maybe one more particle of information is that enums are actually strings, not numbers, so you may have to do a conversion somewhere. this is a pain for us, so we use tiny ints. jeff Mike [tmw] wrote: I always gone with ENUMs b/c TINYINT(1) still allows you to insert a '2' into the field and the last idiot at my current job actually used '0' for 'true' in a some fields in some tables.

You could try something vaguely like this:
# mkdir -p cd /tmp/mysqluninst
# cd /tmp/mysqluninst
# tar xvzf path-to-mysql-bin.tar.gz
# find . -exec rm /{} \;
DO NOT RUN THIS if you do not understand how it functions. It may
contain bugs, and I won't be responsible if you blindly run it and it
eats your filesystem. Even if you think you know how it functions, you
should probably replace the 'rm' part of the last command with something
harmless so you can ensure that it does the right thing before
re-issuing the command with 'rm' instead.
If you don't understand what I have done above and you are unwilling to
learn, just disable the mysql server and don't bother erasing its files.
It's probably only a few megs of disk space anyway.

No, it's perfectly possible. I have dozens of versions installed on my main machine.

create own auto increment number
I have a request to create an auto increment field that increments like so: 1-112403 2-112403 3-112403 4-112503 etc... Is that possible???

There could be a number of things going on.
It would help troubleshoot your problem if your
script check for errors and print them if there are any. You cant
just assume a connection is being made just because phpmyadmin
connects.
Your web app has to make its own connection.
So how about showing us one of your scripts. I bet it is something
simple youre overlooking in your setup.

The best way to learn is by taking a script (I used a message board written in php/mysql) and hacking it, then running it on your webserver, breaking it, and fixing it again. Just make tiny changes at first, play with logic, then work on bigger things. As for a book, I recommend the one on PHP and mySQL web development by Luke Willing and Laura Thompson. Good luck!

Which Linux....
I'm building up a new MySQL server. The box specs are: 2U, Dual 3Ghz Xeon processors, 6 Gigs ram, 500 gigs of Raid 5 storage. I'll have the hardware in my hands tomorrow. I've used RedHat on all my previous linux servers. I'm planning on going with Red Hat Enterprise Linux ES. But, I've heard that the new threading code in the latest linux kernal (2.6) really improves MySQL performance. The RedHat site says that Enterprise is based on the 2.4 Kernal, with numerous additions from the Linux 2.5/2.6 kernal. And I just spotted another place where it mentions Native Posix Thread Library: A new high-performance multi-threading capability provides improved performance for multi-threaded applications. So, am I assuming correctly that RedHat Enterprise does offer the new threading code? Anyone know any problems using the new RedHat Enterprise for MySQL? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Problem with merging tables
I am getting the following error when I try to access a merged table:
This:
Select * from subjects_2; or insert into subjects_2 (subj_id) values('10');
Returns:
ERROR 1017: Can't find file: 'subjects_2.MRG' (errno: 2)
Any Ideas what this means and how I can correct it. I can access the two
tables merged by this table, just not the merged table itself.
Merging tables are new to me so take it easy on my novice self...

InnoDB caused crash and left me a log entry...
InnoDB seems to have crashed on us, and put the errors below into the log files... It took several crashes and some time but I was able to isolate the extremely simple query involved. Server is OSX 10.3 running on a Dual 200MHZ G5 with 4Gigs ram. MySQL is 4.0.16. The original queries to crash were a little longer in that they also updated the field description with a large block of text as well as the field name. The following Queries repeatedly caused a crash when executed from the mysql command line directly to mysqld with no other client connections open: update jiveForum set name='Technical Questions: SDK' where forumID=4; update jiveForum set name=Technical Questions: SDK where forumID=4; update jiveForum set name='Technical Questions - SDK' where forumID=4; update jiveForum set name='Technical Questions' where forumID=4; These queries did not cause the crash: update jiveForum set name='Technical' where forumID=4; update jiveForum set name='SDK Questions' where forumID=4; I eventually moved the table out of InnoDB, made the changes, and moved it back to InnoDB again without experiencing further problems. In order to restore client services I did not try again to reproduce the problem, instant Database server crash is not an attractive experience, especially in our production environment.

strings of variables, php, mysql
Would appreciate in anyone can help me. Let's say I do a query in php, eg. $query = select shed from structure; With the mysql_fetch_array function and a loop I could see all the values stored in the column, shed, using the command: echo $shed; Let's say now that I am carrying over a variable from a form called $form where $form = shed. I can still say $query = select $form from structure; because $form = shed. The problem I have now is with the strings and how do I see my column values. Using echo $$value; or echo $($value) or echo \$$value or echo $$value does not give me the values stored in the column shed. Help anyone? thanks __ Do you Yahoo!?

Re: SHOW TABLE STATUS without LIKE
Hi! Please reply to the list, not to me personally, so that others can follow this discussion. Thanks. Sorry, At 13:21 +0200 11/21/03, Jozsa Boti wrote: Hi! How an i get the last Check-time of a specific table without using LIKE statements? There isn't another way. There's the SHOW TABLE STATUS command, but if there are many tables in a database this command is very slow, even if a specific table name is after the LIKE statment. Slow? How many tables are we talking about? I'm talking about nearly 20 000 tables in a database. In this case a SHOW TABLE STATUS commande takes about 20-30 seconds. Hm, that is pretty slow. How long does an ls command in the database directory take? About 1-2 seconds.

The PHP mailing list is a good place to go when your stuck, as well as this mailing list when you need to solve a MySQL problem (after you've googled and searched the archives that is ;).

RE: How To Learn php and mysql.

The best way to learn is by taking a script (I used a message board written in php/mysql) and hacking it, then running it on your webserver, breaking it, and fixing it again. Just make tiny changes at first, play with logic, then work on bigger things. As for a book, I recommend the one on PHP and mySQL web development by Luke Willing and Laura Thompson. Good luck!

RE: Compare dates
Hi Manisha I have used the same thing in a pretty different way. Basicallyi have stored the date in string format say 'MMDD' and then done simple comparison say 2003112520031029 by converting it into Long format in my local code (note::this will specially work in case of MMDD format as future date will always be greater than past date in Long Format) Though this may not solve your problem completely but i hope this gives you some pointers. regards Kams -Original Message- From: Manisha Sathe [mailto:[EMAIL PROTECTED] Sent: Monday, November 24, 2003 6:50 PM To: [EMAIL PROTECTED] Subject: Compare dates I have a table with start_date (date), end_date (date), rate(float) as 3 fields, I want to compare today's date with start and end date if it is inside this range then pick up the corresponding rate.
