Join causing Error?
Can anyone tell me why this:
Line 282mysql_select_db("centraldb",$db);
Line 283$qorder++;
Line 284$result = mysql_query("SELECT q.questid, q.question, q.answer, q.qorder,
q.depart, q.catid,
q.active, q.global, q.adate, q.author, q.authoremail, q.askemail,
c.catid, c.category, c.under,
c.corder, c.active FROM central_groupfaqq q, central_groupfaqcat c
WHERE q.active = '1' AND
q.global = '1' AND c.active = '1' ORDER BY c.under, c.order,
q.qorder",$db);
Line 285while ($myrow = mysql_fetch_row($result))
Would cause this error:
Warning: Supplied argument is not a valid MySQL result resource in faqbody.php3 on
line 285
When changing the same SELECT statement to:
Line 284$result = mysql_query("SELECT * FROM central_groupfaqq WHERE active =
'1' ORDER BY
qorder",$db);
Works perfectly?

Re: Index Usage weirdness
I got to wondering about that after your question about how many rows were there. I was just playing with a test copy of the db, preparing to set the log options on the production one, and noticed that. I rummaged around in the .pdf version of the manual for over an hour before posting the question. Obviously, I missed it. Maybe I should've gone to bed earlier instead. It certainly makes sense for MySQL not to use the index in that case, of course. As for me, it's another situation of: If you're gonna train a dog, it helps to be smarter than the dog. Thanks!

ROLLBACK not working in Red Hat Linux 7 but does in RedHat Linux 6.2 (MySQL3.23.33)
Hi all, has anyone also seen problems with ROLLBACK not working when installing MySQL on Red Hat Linux 7.0? On Red Hat Linux 7.0, ROLLBACK does nothing (though it doesn't generate an error either, and the table is listed as a BDB in show table status, and locking works as expected with a BDB table). Is there a known problem with RH7? I am using an all-defaults Red Hat server installation. On a stock Red Hat Linux 6.2 server installation, it works. I found a number of people mentioning they had problems with RH7 and ROLLBACK on the mailing lists, but with beta versions, not the stable code. I am installing from tarball source using the following configuration: shell ./configure --prefix=/usr/local/mysql shell make shell make install shell scripts/mysql_install_db shell chown -R mysql /usr/local/mysql shell chgrp -R mysql /usr/local/mysql shell /usr/local/mysql/bin/safe_mysqld --user=mysql And this is my BDB test: create table bdbtest (pk int primary key, name varchar(20)) type=bdb; begin; insert into bdbtest values (1, 'tim'); rollback; select * from bdbtest; (I see the row but should not) set autocommit=0; begin update bdbtest set name='tim2' where pk=1; rollback; select * from bdbtest; (the row was updated but should not have been) All these commands complete OK without errors. In Red Hat 6.2, the changes are indeed rolled back. This testing in part of a review I'm doing for eWEEK on this release of MySQL.

Re: What index is needed to speed up query?

Re: Table joining/setup advise?
Sir, you are trying to construct a many-to-many join. (One list has many members, one member subscribes to many lists.) This is done with a join table. join_lists_members(list_id, member_id) To get all the e-mail addresses for a given list name, use SELECT m.email FROM (lists AS l INNER JOIN join_lists_member AS j ON l.id = j.list_id) INNER JOIN members AS m ON j.member_id = m.id WHERE l.name = some list name; This is a little complicated, but it is the standard way of doing it, and it doesn't limit either lists or members. Bob Hall Hi, I`m setting up a email system, the same type of system as Yahoh Groups, Topica etc.. I`m just in need of some advise as to how best to handle my tables. At the moment I have the following tables setup.. Lists - Stores info about the list ListOwners - Stores all List Owners info Members - Stores all member info Archive - Stores all messages sent to the lists I am trying to figure out the best way to associate Members with Lists that they have signed up to, at the moment I can only think of 2 methods both of which wouldn`t be very good. First being to have a couple of fields in the Members table which would store the title of the list they signed up to, the problem with this is that they would be limited to how many lists they sign up to. Second method would to store in the Lists table the members ID but again this would be limited to however many rows I create. Another method I have just thought of would be to create a table called Subscribe and store the List name, Member ID and email address. But that might slow it down a bit when searching for the email address`s to send the actual message out. Any one else offer any thoughts on this.

Re: [PHP-DB] Join causing Error?
Sir, I don't see anything wrong with the syntax in your query. If I
haven't over looked something, and if you haven't misspelled
anything, then you have a data problem. Since your first query
returns a Cartesian product, you should get something if the WHERE
clause returns = 1 row for each table. So either there are no rows
in q that meet the conditions
q.active = '1' AND q.global = '1'
or there are no rows in c that meet the condition
c.active = '1'
Run the first query with only the first WHERE condition. If you get
rows, add the second condition. If that works, add the third. The
point at which the query stops returning rows is the point at which a
subset of your WHERE conditions aren't met by the any of the rows in
one of the tables.
BTW, why are you putting quotes around numbers? I'm assuming that's
not the problem, since you say you did it in the query that worked,
but I don't see the point.

Re: Problem installing MySQL php
I had pretty much the same problem. I was unhappy with the RH v7.0 distro of MySQL and downloaded the MySQL rpm's (v3.23.33). It installed and ran with _no_ problems! My problem was the RH distro of php did not recognize that MySQL was there. I decided to upgrade to php 4.0.4. I downloaded the rpms from RH, but when it came time to install php-mysql, it said MySQL was not there. I was very reluctant to uninstall php and try to install and compile the tarball. What I did instead is... rpm -ivh php-my*.rpm --nodeps This installed mysql-php without checking for dependencies. After a reboot, I can connect to MySQL databases with php.

RE: XML support under mySQL
Glorious Sunday morning greetings to you Jan, No, XML is a format for 2 different applications, usually 2 totally separate applications, to be able to exchange data. It is not an appropriate choice for storing large amounts of data that will have to be queried. Nor is it an appropriate choice of language for talking to an RDBMS. Outside of the fact that it can be extremely verbose, we already have a perfectly good language for that, SQL. SQL is a language for committing data to a storage mechanism and retrieving the data back. It is superior to XML in those tasks. Again, if you have need to talk to your RDBMS via XML then a thin wrapper written in the language of your choice is the proper way to go. This allows you to do your job without bloating my application with unnecessary code. And I also disagree with your statement that there is no difference between metadata and data. there most certainly is. But that's a discussion for another thread. humbly, Cal http://www.calevans.com p.s. another reason not to include it is NOBODY wants to distract the MySQL coders from getting 4.0 frozen and out the door! :) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jan Dvorak Sent: Sunday, February 25, 2001 10:13 AM To: Ed Carp Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: XML support under mySQL Ed Carp wrote: Gorjan Todorovski ([EMAIL PROTECTED]) writes: Since XML is a way to exchange data...and it is protocol/platform indepdnent there is a very good reason to have XML docuemts going in and out the No, it's not.

missing library libz.so

I've found that file online and copied it into all myysql directories but still it can't load the file. I propably should copy the file to the /local/lib directorie or something, but I can't acces those directories. So is it possible to disable the use of this lib or can I specify the path to it?

Setting access rights
Hi everyone,
I have problem with Database inteded for setting access rights.
The problem is that IP addresses set in table 'db' dont affect access rights.

INSERT INTO user VALUES
('localhost','root','passwd','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y'
,'Y');
#
# Dumping data for table 'db'
#
INSERT INTO db VALUES
('localhost','XXX','YYY','Y','Y','Y','Y','N','N','N','N','N','N');
INSERT INTO db VALUES

Re: Redhat 7 newbie.....
Hi: Make sure MySQL is started when your system boots up. Run 'setup' as root and go to 'System Services' and make sure mysqld is checked.

Random record
Does anyone have any good ideas on how to pull a random record? I've been using PHP's random function to create a random number to pull, but the problem is that if I delete a record, it could still try to pull it. Is there a better way? I'd really like to be able to just pull it in the SQL statement instead of pulling a bunch of records then sorting throught that. Thanks, JOE

Dear Sir/Madam,
I'm a Visual FoxPro programmer. I want to use MySQL database for my
programs. However, I cannot update MySQL database with my Visual FoxPro
programs through ODBC (but I can view the record of table). My commands
are as follow:
CREATE CONNECTION conn1 DATASOURCE "MySQL" USERID "users" DATABASE
"tempdata"
STORE SQLSTRINGCONNECT('dsn=MySQL; uid=root; pwd=') TO
xConnHandle //return of 'xConnHandle' is positive that means
connection is successful//
=SQLSETPROP(xConnHandle,'Transactions',2) //this return is
negative that means there is an error on connection level//
I don't know why I can view the table but I cannot update the table
through ODBC. Would you help me to solve this problem? Thank you!

Edith

Re: Random record
Instead of pulling using equals, ie "select * from table where id = $php_random_variable" you can do this instead "select * from table where id = $php_random_variable LIMIT 1"... As long is there is atleast one row in the table you will get back a result.

RE: XML support under mySQL
At 10:37 AM -0600 2/25/01, Cal Evans wrote: Glorious Sunday morning greetings to you Jan, No, XML is a format for 2 different applications, usually 2 totally separate applications, to be able to exchange data. It is not an appropriate choice for storing large amounts of data that will have to be queried. Nor is it an appropriate choice of language for talking to an RDBMS. Outside of the fact that it can be extremely verbose, we already have a perfectly good language for that, SQL. SQL is a language for committing data to a storage mechanism and retrieving the data back. It is superior to XML in those tasks. Is anybody on this thread really rationally suggesting using XML instead of SQL? I hope not. It would no longer be an SQL database. Of course SQL is the language for committing data to the storage mechanism. What the data consists of is another matter. If some of my data is a paragraph of text of which some of the words may be bold, others italics and so on, then I will want to make this formatting information part of my data by using XML, RTF or some other tagged structure. If anyone is suggesting that I shouldn't ever do this, but only use raw data, then they are nuts. On the other hand if its being argued that the formatting information should be separated from the raw data because you may want to look at it in both forms, I can buy that, but the formatting information is still data, still stored in the database, maybe just in a separate field if you like. If anyone is arguing that the formatting information should be stored in some other database, they are also nuts.

Max_allowed_packet variable ??
Hi, This is how I set the variables in the my.cnf file. [mysqld] set-variable = key_buffer_size=16M set-variable = max_allowed_packet=16M I can only insert 8M at any one time using SQLPutData. Even if I insert 1024K more, the SQLPutData will return a "Function sequence error". Does max_allowed_packet means half of what is stated? Coz I tried setting the max_allowed_packet=2M, and eventually I can only insert 1M at any one time. I'm not sure whether I have to set any other variables as well. Please advise. Thanks, Li Sze

I'm assuming this is on Solaris. One workaround that you may be able to do is to set you LD_LIBRARY_PATH to the path where libz.so is. I've seen this problem with other products and it turned out to be a Solaris install issue. I had to back rev to 2.7 in order to get it to work.

Can't drop tables
I just installed mysql 3.23 and then ran a script to create a database I had previously been using in an older version. I have a couple questions. First, how can I make a drop database statement not fail if the database doesn't exist. A book I was using seemed to say: drop database dbname if exists; Would work, but I get an error with this. What is the correct syntax? Second, on this newest installation, I can't drop a database. I get the error "failed to rmdir ./dbname, errno 21" or something similar. If I su to my mysql user, and cd to the data directory, an rmdir dbname works successfully, so I'm not sure why this is failing. The actual data files in the database are all gone after the drop statement. Only the empty directory sticks around. Any help would be appreciated.

Server Tuning
Hi I am running Mysql on a Machine with two PIII-600, and 1 GB of RAM. The disks are connected via U2W-SCSI. I tried tuning mysql for maximal performance the last days, but I'm not exactly sure which parameters I should increase, und to what value. Our web application is quite slow at the moment, and often the server is slower in doing the queries than they are created by the users, which steadily increases the number of running mysql-processes until they reach max_connection (which is 100 at the moment). Our Application searches through about 1.000.000 Records, and does heavy grouping, sometimes over 100.000 records. Is there any chance, that we can keep doing this queries on the fly, or will we have to cache them somehow? (which has a _lot_ of downsides, since the data changes quite frequently, about once every 1/2 hour). Which server parameters should we increase to make things faster? Since a lot of users "do the same thing" on this website, we often have the very _same_ query running 5 to 10 times, one started within 5 seconds or so after the other. Is there a way the prevent mysql from doing the query twice, and instead just wait for the first to be finished and then return the result to both clients? If not, I will code this feature in PHP, using shared memory unless anyone has already done this and is willing to share the code.

Coz I tried setting the max_allowed_packet=2M, and eventually I can only insert 1M at any one time. I'm not sure whether I have to set any other variables as well. Please advise.

Re: mysql is really a slow rdbms
It is not that mysql it slow, its your database design and the fact you have 2.5 million records in the table. It is not clear from your description of the problem what you are trying to do, so giving advice is that much harder. If you are creating an index on the column hari, it will take a long time. However this time is negligable because you only do it once, and never again. But if you are talking about a query that uses the column hari going slow, making it a key in the table will speed up your query considerably. Hope this helps. This table contains more than 2.5 million records. I created index on column hari. It needs more than 3797 secs, and have not finished yet.

Re: XML support under mySQL
Michael, Is anybody on this thread really rationally suggesting using XML instead of SQL? I hope not. It would no longer be an SQL database. Of course SQL is the language for committing data to the storage mechanism. What the data consists of is another matter. I'm suggesting there is a good reason for allowing access to a database in XML in parallel to SQL. I don't care it wouldn't be an SQL database. Please, read on. If some of my data is a paragraph of text of which some of the words may be bold, others italics and so on, then I will want to make this formatting information part of my data by using XML, RTF or some other tagged structure. If anyone is suggesting that I shouldn't ever do this, but only use raw data, then they are nuts. On the other hand if its being argued that the formatting information should be separated from the raw data because you may want to look at it in both forms, I can buy that, but the formatting information is still data, still stored in the database, maybe just in a separate field if you like. If anyone is arguing that the formatting information should be stored in some other database, they are also nuts. You shouldn't forget that formatting markup is just one use of XML. The other one, perhaps the by far the most progressive one, being semantics markup. To see the difference, let's take the example of an invoice. If it's represented in a formatting-driven markup, it goes like: h1Invoice no. 1/2001/h1 p iCustomer:/ibr / MathAn Praha, Ltd.br / Dlazdena 4br / Prahabr / CZ-11000br / Czech Republicbr / Europe /p table tr thItem #/th thItem description/th thQuantity/th thUnit price/th thAmount/th /tr tr td1/td tdMySQL license/td td1/td td200 USD/td td200 USD/td /tr tr td2/td tdMySQL e-mail support/td td1 year/td td170 EURO/year/td tdEURO 170/td /tr tr th colspan="4"Total/th tdb342.45 USD/b/td /tr /table That was HTML, purely presentation. But machines will also need to understand invoices. The same invoice could be written as: invoice id="invoice:1/2001" customer party company-nameMathAn Praha, Ltd./company-name address type="street" site="HQ" address-linestreetDlazdena/street house-number4/house-number/address-line address-linezip-codeCZ-11000/zip-code cityPraha/city/address-line address-linecountryCzech Republic/country, continentEurope/continent/address-line /address /party customer invoice-lines invoice-line order="1" item code="124897435" description xml:lang="en"MySQL license/description description xml:lang="cs"Licence MySQL/description /item quantity units="piece"1/quantity unit-price units="USD/piece"200/unit-price amount units="USD"200/amount /invoice-line invoice-line order="2" item code="124897439" description xml:lang="en"MySQL basic e-mail support/description description xml:lang="cs"Zakladni e-mailova podpora MySQL/description /item quantity units="piece/year"1/quantity unit-price units="EUR/piece*year"170/unit-price amount units="EUR"170/amount /invoice-line /invoice-lines invoice-total total units="USD"342.654/total /invoice-total /invoice O.k., a real invoice will have a bit more information in it, but that's not important here. Now, take the data-oriented markup. To represent the same information in a relational database, you'll need several tables: Invoice, InvoiceLine, Item, ItemDescription, Language(a look-up table), Unit (another look-up table), Party, and Address. You can parse the document and isolate every XML element value and every XML attribute and insert them into appropriate columns of the tables. Probably a glue script to do this is the best choice today. Likewise, you can take the data stored in the tables of the RDBMS and run "a few" selects on them and combine the results in such a way that the XML document for the invoice comes to existence. Again, a glue script is a clear candidate to do the job. Now, I'm claiming that in a future that's not at all distant, the need to do these conversions more and more often will lead to the following consequences: 1. The XML - RDBMS translation will be understood theoretically and a formal language to describe the mapping will arise. 2. DBMS's will be incorporating the translation functionality, for efficiency and ease-of-use of the XML side of a DBMS will get focus. The XML interface will call the internal storage API of the DBMS, not any SQL tier. 3. With XML becoming more and more popular, data structures we'll be getting from a DBMS will move from linear tables to trees. Even internally, the database engines will start storing data in something else than tables. 4. The SQL interface will continue to exist and work, but it will not be the only interface to the data in the database. Alternative interfaces will rise, some of which may be based on XML. Michael, admit that an XML interface to database would give additional
Re: mysql is really a slow rdbms
Just simple question.. why u designed it such a way that differentiate the 'thn','bln' and 'hari' field when you can do it just using one field and using DATE type field instead of integer. and when you query u can use your SQL sorting to speed up searching.

Re: XML support under mySQL
Cal, Cal Evans wrote: Glorious Sunday morning greetings to you Jan, No, XML is a format for 2 different applications, usually 2 totally separate applications, to be able to exchange data. It is not an appropriate choice for storing large amounts of data that will have to be queried. But the XML markup is just a manifestation of a deeper structure: trees. Trees are more general than tuples, a piece of XML can convey more information than a piece of a relational table. Nor is it an appropriate choice of language for talking to an RDBMS. Outside of the fact that it can be extremely verbose, ...it compresses magnificiently... we already have a perfectly good language for that, SQL. SQL is a language for committing data to a storage mechanism and retrieving the data back. It is superior to XML in those tasks. No. SQL is limited by the linear structure of tables. If you need to retrieve/store more complex information, you need to place several SELECTs/INSERTs in a row. Compare this to the rich structure of trees XML is based on. I know I can represent a Request for Quote in one XML document, but the same thing would take me five tables of a relational database. I know I can represent a Quote - which is a result of the Request for Quote query - with just one XML document, while the same thing would take me at least four relational tables. Again, if you have need to talk to your RDBMS via XML then a thin wrapper written in the language of your choice is the proper way to go. This allows you to do your job without bloating my application with unnecessary code. I'm already tired of thin wrappers. Plus they are not exactly efficient; the two overheads are in place and hogging: 1. The client/server communication overhead, even if we go locally thru a socket; 2. The SQL overhead of having to parse, understand and optimize a query can kill you on thousands of queries. As a rule, new functionalities in MySQL are optional. You don't have to enable them. And I also disagree with your statement that there is no difference between metadata and data. there most certainly is. But that's a discussion for another thread. It's always data. You call it metadata if it describes some other data. But on its own, it's data in the first place. humbly, Cal http://www.calevans.com Yours, Jan p.s. another reason not to include it is NOBODY wants to distract the MySQL coders from getting 4.0 frozen and out the door! :) Hey, eventually a good reason against XML in MySQL! -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jan Dvorak Sent: Sunday, February 25, 2001 10:13 AM To: Ed Carp Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: XML support under mySQL Ed Carp wrote: Gorjan Todorovski ([EMAIL PROTECTED]) writes: Since XML is a way to exchange data...and it is protocol/platform indepdnent there is a very good reason to have XML docuemts going in and out the No, it's not.
