Hi there, I have recently upgraded from mysql 4.0 to 4.1.x Now I am facing an error while issuing this delete command: # delete report images in db $stmt= " DELETE FROM $DB.$T21 USING $DB.$T21 AS rp, $DB.$T13 AS r WHERE r.ID = rp.recommendations_id AND r.user_recommending = '$user_id' "; Error: 1109 Unknown table 'the_table_name' in MULTI DELETE Has there something changed in the syntax?

Mysql takes server down
Hi everybody, I am running a LAMP installation with mysql 3.x installed. Since a few hours the szstem load goes up till the server crashes. I have to reboot it, and then 60 minutes later it is gone again! Server is running now for over 2 years. I do have the impession that mysql is the reason for it. Since I have disabled the webapp, but as soon as I start mysql the system starts going down. has anybody an idea what is going wrong?

Performance - one integrated LAMP vs. seperate web, DB Server
Hi there, I do have a LAMP app that currently does run on a 1GB i686 Prozessor. The system is getting slower since traffic is raising. So I ordered another dedicated root server with an Opteron 4GB Raid System. I intended to run the second box as a pure DB Server and do the PHP and Weberserving stuff do the old machine. Here is the problem: After the system is setup, I noticed that I have to configure mysql with SSL, do some other restrictions and that latency might become a problem since I do not really know where the boxes are located within my provider (same one). Which version do you think will be the faster and/or smarter way to go: 1. Put all on the new box and let it handle mysql via socket without SSL between web/db 2. Put on seperate boxes, go over SSL (MySQL4.1.22), without static compile option (does not work with SSL), connected through internet. Option one would also be 100 Euro cheaper per month. Server load is currently between 1.5 and sometimes 5. Thank you for any help on this triky question.

Default root password not blank?
Hi there, I just compiled mysql4.1.22 on a suse 9.3 machine. All went fine, but when I try to change the password I get prompted for one. So I hit return as it is supposed to be blank, right? But it seems to be not: /usr/local/mysql/bin # ./mysqladmin -u root -p password testpw Enter password: ./mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' if I do the command without -p I get: ./mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' Is there a special command for "blank"? As I noted using password NO for hitting return.

Query to slow after inserting another table
Hi there, I am using mysql 4.0.18 and do want to do the following: There is one table with classifieds that contains the title and the text. Another one contains tags associated with the classifieds. Each classified row can have multiple tags inside the tag table. The tag table contains the ad_id which is the ID of the classified table. Without querying the tag table the query takes just 0.000x seconds, but with the tag table it takes over 0.3. Indexes are set properly, as far as I can see. This is my query (involves some other tables as well, but they the performance problem lies with the tags table. SELECT cp . * , UNIX_TIMESTAMP( cl.timestamp ) AS date, cl . * , MATCH ( cl.text, cl.title ) AGAINST ( 'anzug' IN boolean MODE ) AS relevance, ar.area_name, ar.area_name_secure, cs.name_safe AS sub_ns FROM classifieds cl, de_cat_sub cs LEFT JOIN classifieds_pix AS cp ON cl.ID = cp.classified_id LEFT JOIN area_names AS ar ON cl.area_id = ar.ID LEFT JOIN tags AS ta ON ta.ad_id = cl.ID WHERE cl.confirmed =1 AND cl.country = 'de' AND ( ( MATCH ( cl.text, cl.title ) AGAINST ( 'anzug' IN BOOLEAN MODE ) ) OR ta.tag = 'anzug' ) AND ( 1 ) AND cl.cat_id = cs.ID GROUP BY cl.ID ORDER BY relevance DESC , cl.timestamp DESC LIMIT 0 , 20 Doing an explain brings up: table type possible_keys key key_len ref rows Extra cs ALL PRIMARY NULL NULL NULL 53 Using temporary; Using filesort cl ref cat_id,country cat_id 2 cs.ID 85 Using where cp ref album_id album_id 3 cl.ID 1 ar eq_ref PRIMARY PRIMARY 2 cl.area_id 1 ta ref ad_id ad_id 3 cl.ID 2 Using where I am completly lost here. I assume that there is a much better way to include the tags table into the search. Any ideas? Thank you for any help on that.

Re: updates during database dump
Hi, I think there is another usable method to backup databases in MySQL. And that is using a slave server, (that can be running in the same server), and when backuping up the databases you do (in the slave): STOP SLAVE; -- This will stop the replication -- Now you backup the databases (using mysqldump or anything you prefer) from the slave server START SLAVE; -- This will restart the replication This way you have a consistent snapshot of your database, without stop the main database, that is being used to whatever aplication you need.

fulltext search on words inside words
Hi there, I am wondering if it is possible to find words inside words with the help of fulltext search. For example: Search for: "Antenne" Schould also find "Stabantenne" Is this possible? Google does that, so somehow there should be a way. Another thing is, how do I exclude popular words like "and" "for" and similar from the search? Is there a MySQL setting for this.

deleting unwanted rows
Hi there, I just discovered, that I do have some old rows I do not need anymore. A result from forgeting to empty the table before starting to go into production :-) However, I do try to find the rows which are not asociated with another table in order to delete them. I have 2 tables: table1 and table2 table1 has the key: "ID" table2 has the subkey "table1_id" Now I would like to delete all rows in table1 which are not listed in table2 with an id. I tried: SELECT t1.* FROM table1 as t1, table2 as t2 WHERE t1.ID != t2.table1_id But this returns hundreds of thousends of results. I also tryed to group by t1.ID, but it did not help Does anybody have a good idea how to get rid of those rows? Thanx, Merlin PS: Thanx for the answer for the question with full text search!

oix ppl, thanks a lot for the answers, but if it was this simple I wouldn't ask... Yes, I am Core Certificate, and yes I did read the show-table-status page. BUT, that don't satisfy my needs. The sugestion to use data_length divided by the number of rows is good if all rows have a fixed length, that don't happen if there is one or more text/blob field in the table, in which case the row size is diferent depending in that field(s) content.

Hi, Tihs looks to me as too few information. What is in your tables (the information)? What does the query return (a empty set)?

stressing mysql - configuration advice
Hi there, I just installed the newest mysql 4.x server on a suse9.0 system with apache 1.x and php4.x The system is a p4 2.4G with 1GB of RAM. It serves one LAMP application. Now I am trying to configure the server for huge load. To stress test it, I installed the Microsoft stress test tool which simulates 300 threads in this case. I configureed the server with following settings: key_buffer = 348M max_allowed_packet = 1M table_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M myisam_sort_buffer_size = 64M thread_cache = 8 query_cache_size= 16M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8 Problem is: The server can't satisfy each query request once more than 200 threads are issued. Result is that the application does not respond anymore. I have a php script which redirects users if the db does not respond to a query. This is the only site they get with the current settings. Is it possible to increase the number of users? I think this might be the main problem in my case. Any advice is apreciated. I am just starting to understand how to configure mysql server.

Re: Decrypt MYSQL Password
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Ben, From the MySQL man online @ http://www.mysql.com/doc/en/Miscellaneous_functions.html#IDX1330 : PASSWORD() encryption is non-reversible. To create a forgot your password page, the best method is to generate a net password and send that new password. To make it easier to your users to remember their passwords, the best way is to set that password as a temporary one, that only allows them to set the original password. (maybe using a diferent field, so they can keep the original password if someone else goes to your site and request the password, just because he was bored.

Hi Toby,
Two points:
First, I presume you're quotting ($dbh->quote(...)) your data between
the
cgi retrieve and that your insert. if you aren't, you should.
Second... well it depends on the browser you're using on your testes.
Some
browser with check boxes like yours (with no value) send only the field with
no value (an http parameter like this ...&news_letter_subs=&...) and other
send an ON value on checked checkbox fields with no value (an http parameter
like this ...&news_letter_subs=ON&...) - In this last ones your wuery should
work at all if as i presume your field is numeric.
I presume that your field is a numeric, so mysql uses the '' value as a 0.
What you must do is one of two things. Depending on the way you parse/the
module you use to parse your query string, you must check if your parameter
news_letter_subs is defined. And if it is defined your checkbox was checked,
since unchecked checkbox fields are not sent.
Or, the simplest way, just change your HTML to this
sign me up fo weekly news
letter and updates
And this way, the value you get if the field is checked is allways 1.
