That version of FreeBSD has threading issues. I've found that they go away completely if you upgrade to FreeBSD 4.3. And you'll probably want to use a newer MySQL just to stay current (3.23.41 works well). Jeremy -- Jeremy D.

I don't know exactly what you mean, but if I do, I would write
some functions which do the job. For example, this function
retrieves the address of a client from the client ID:
function getAddr($id){
...
}
In these functions, you are not limited in any way except by your
skills and fantasy.

Actually, you sort of answered yourself. Since inicial can have many possible values, odds are that you'll get *fewer* rows by using it to limit the query results. Imagine a table with 1 million records and the keys are equally distributed. Using either "ok" or "sexo" columns will only eliminate about 50% of the rows. The "inicial" column will eliminate many more. Jeremy -- Jeremy D.

Elizabeth, sorry, 1 mistake: binary seems not to support mysql by default. so at least i'm not sure, maybe somebody else can clear this out.

Why can't you just make a copy? You generally save all config files
you can before doing anything in Unix. Make a backup of your entire
/etc dir now:
{ as root } cd /etc
tar czf /some_big_dir/backup/$today_etc.tgz .

Re: Encryption of Data
Elizabeth, Last conversation i recommended tools like ssh (you could also succesfully use stunnel (http://www.stunnel.org), i tried and it works well).. but.. there is an easier way. Guess that it depends on the mysql version your ISP is running, elsewise ask them to upgrade.. Also make sure you have a recent libmysql dll/so. Then use the function mysql_real_connect (see manual: http://www.mysql.com/documentation/mysql/bychapter/manual_Clients.html#mysql_real_connect ) : mysql_init(MyDB); //you must call mysql_init first mysql_real_connect(MyDB,PChar(your_isp), PChar(User), PChar(Passw), PChar(Database), 3306, nil, CLIENT_SSL); This would, if available, use a SSL layer to connect to the MySQL server. I'm not too sure since which version SSL is available, the changelog mentions you can check for 'have_ssl' with "show variables" in version 3.23.30 so at least from this version and up, but maybe functionality is there much longer. Also afaik the binary rpm is compiled with ssl. Also i'm not too sure what happens if ssl is not available (cannot test that now!), maybe it just refuses to connect (desired behavior) or maybe it just connects w/o ssl, i cannot tell. hope this helps. regards, rene On Thu, 23 Aug 2001 08:44:36 +0100 "Elizabeth Alderton" <[EMAIL PROTECTED]> wrote: > Dear Jeremy, Gregor > > Thanks and sorry for not being more specific. > > First of all we use an ISP who runs a Unix server.

data model, tips for online dictionary
Hello all, I'm planning to create an web-based glossary (actually Spanish<>English glossary of retail banking terminology, so my buddies and I can collaboratively prepare to interpret at a conference in a few months). I'll be using either Perl/DBI or PHP, the only languages I speak. Is there anyone out there who has done an online dictionary or glossary and can share some tips about the data model and techniques? I know this wheel has been invented before (yes I checked the archives; someone mentioned he's done one but that's all he says). At the very crudest, I can envision a table such as this CREATE TABLE english_terms ( id smallint(5) unsigned NOT NULL auto_increment, term varchar(255) DEFAULT '' NOT NULL, translation text DEFAULT '' NOT NULL, PRIMARY KEY (id) ); If you wanted to look up a term, your application might say SELECT translation FROM english_terms WHERE term = 'usurious' and so on. I can envision offering the user the option of searching for a term that "is", "begins with", or "contains" what they type into a textfield. But again, I wonder if anyone has any advice. TIA!

If you specify REPLACE, new rows replace existing rows that have the same unique key value. If you specify IGNORE, input rows that duplicate an existing row on a unique key value are skipped.

Looks to me like it would be impossible for fetchrow_hashref() to be
executed without execute() having first been called, because the
test in the if() requires execute() to be called before the test
can be evaluated. Do you have another fetchrow_hashref() call somewhere?
However, execute() returns undef or true for a SELECT statement, not
a row count. You seem to be using it as though it returns a row count.

Re: Changes between 3.22 and 3.23
Well, looks like I found the culprit.
Increasing thread_cache_size from 0 to 50 totally alleviated the stress
(both on the database and our clients). Recommended by the manual,
of course.
For list-archival's sake:
FreeBSD 4.3-STABLE
/etc/my.cnf:
[mysqld]
user=mysql
set-variable = wait_timeout=3600
set-variable = tmp_table_size=800
set-variable = max_connections=500
set-variable = table_cache=256
set-variable = sort_buffer=4M
set-variable = key_buffer=64M
set-variable = thread_cache_size=50
top:
CPU states: 66.3% user, 0.0% nice, 30.2% system, 3.1% interrupt, 0.4% idle
Mem: 33M Active, 92M Inact, 29M Wired, 8368K Cache, 35M Buf, 87M Free
Swap: 1024M Total, 88K Used, 1024M Free
mytop (a great utiltiy, may I add) is reassuring:
Queries Total: 129,866Avg/Sec: 450.92 Slow: 0
Threads Total: 3 Active: 1 Cached: 48
Key Efficiency: 99.73% Bytes in: 16,118,135 Bytes out: 26,368,181
Unfortunately, the application does make a new connection for every
hit, which is why thread_cache_size probably made a difference.
Out of curiousity, what was different about 3.22?
Anyway, Thanks to all who responded.

Replication advice needed...
Hi, We have a somewhat tricky problem that I need some help with. What we have is one machine (the master) that we use for database development, and two dedicated nodes (slaves) on a beowulf cluster that house the non-dev databases. What we need is to mirror the master to the slaves, but not necessarily moment to moment. Once a day or even once a week would be fine. I originally set up replication which worked just fine for a short time. But then I noticed that replication was crashing 3 or 4 times a day. Yuck! I think it had to do with the heavy development on the master- this machine is used to read in new tables from txt files, create loads of temporary tables and in general get beat to hell. It seemed that the slaves were choking on some particular line from the binary logs, and could not get going again. Speaking of which, how to start replication at the next 'good' line number? I couldn't figure out how to find that line number. Anyways, I scoured the docs, but could not find a list of what happens for example if the master loads a new table from a text file. Does this command 'read ... from infile...' go into the binary logs? What happens to the slave when it tries to read in a text file that doesnt exist? What kind of errors can the slave deal with, and which ones cause replication to fail? For a while, I just figured replication was a bad idea with a development db as the master. But then when I tried to find alternatives, I hit another brick wall. A bit off topic, but how does one take a 'snapshot' of the master db and migrate that out to the slaves? Besides the obvious and (imho clumsy) tar, gzip and scp of about 4 gigs of data, I thought of adding the entire db to cvs, but then there are inherent problems with that ( try adding a 1.2 gig table to a repository when you only have 256 megs of ram :P) Is replication the right tool for this job? If it is, what is the best model for our needs? If not, does anyone have any other suggestions?

blobs
how would i get a file such as /files/photo.jpg into a mysql table such as
create table photo ( code decimal(6,0), photo blob);
i tried insert into photo values('4142','/files/photo.jpg'); which of course
just put the file name into the 'photo' column.

Re: store and display image with java
Bin Cai schrieb am Donnerstag, 23. August 2001, 23:24:01: > could you tell me how to store image in mysql database and display on web > using java. urgently Do it like any other insert, but care for special characters. In php, you would wrap data with addSlashes() and remove them on retrieval with stripSlashes(). But... you better not insert images into a table. Yes, you can do it, but it is generally considered a bad idea. Read about it at http://www.bitbybit.dk/mysqlfaq/ - if the images have to be provided by users, use the upload functions of your system. php for example has upload support built in. Next you have to care for the appropriate write rights for those files. These can be handled safely without compromising system security. Store all data associated with the pictures in a table except the picture itself, which should be taken care of by the file sytem. rasmus on files in databases: When dealing with images, it is of course possible to insert the image data into the database as binary blobs. However, the value in doing that is questionable. Until databases provide you with cool pattern recognition tools that will let you search a blob for a picture of a rose, having the image data itself in the database isn't of much use. Every operating system comes with a finely tuned blob database. It is called your file system. So, just put the full-path filename into the database and leave the images sitting somewhere on your disk. You will save yourself much aggrevation in the long run. http://conf.php.net/pres/index.php?p=slides%2Fintro&id=or2001 Herzlich Werner -- MySQL in Deutschland: Anpassung, Unterstützung, Schulung für Sie __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Dr. Werner Stürenburg <[EMAIL PROTECTED]> / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Consultant /_/ /_/\_, /___/\___\_\___/ Bielefeld, Germany <___/ www.mysql.com +49-5224-997-407 Fax -409 - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Changes between 3.22 and 3.23
We upgraded our convergent e-business enterprise database server from mysql
3.22 to 3.23 yesterday. The upgrade process itself was smooth and
sexy.
Unfortunately, the dbms is overall slower for us. What's worse,
some maintenance scripts are losing their connections in the
middle of their runs.
I have indeed read the appropriate section in the manual for upgrading
from 3.22 to 3.23.
I have a number of hunches as to where I could start, but I was just
wondering if there is anything I should be aware of that may save
me some time ("You idiot, mysql 3.23 introduced a turbo switch. It's
just off by default").
Thanks.

mysql import problem
Hello List! I am having an extremely unusual problem with MySQL3.22.27 running on a Sun UltraII Solaris 7 (latest patches applied). This implementation of MySQL 3.22.27 has been rock solid for better than 2 years now. We have a primary/failover system here, and the primary 'syncs' itself to the secondary via mysqldump every X hours. What has been happening is, on the failover box, when importing the dump from mysqldump the db hangs. Connections are allowed, but access to the db in question freezes. I have done quite a bit of debugging, and have determined that the freeze occurs as the 'user' table is getting loaded. I recompiled mysql with debug on, and the log file for the import dies right after trying to load that table. Additionally, after a freeze, I can restart mysql, and look at all of the db, except that user is an empty set (should be about 81000 records). I have the _exact_same_ dump occuring to a different box running the same version of MySQL just fine, religiously. I have fsck'ed the drives that the mysql instance lived on (no problems). I trussed the mysql process below with no relevant output (will post to the list if requested). I have recompiled and reinstalled mysql with the same results (having first deleted in entirety the old install) Information: Command to import: bin/mysql -uroot -pblah dbname < /path/to/mysqldump User table info: bin/isamchk -d var/layoutwizard/user.ISM ISAM file: var/layoutwizard/user.ISM Data records: 81491 Deleted blocks: 0 Recordlength: 301 Record format: Packed table description: Key Start Len Index Type 1 1 4 unique long 2 9 8 multip. binary 3 5 4 multip. long 4 45255 multip. text Any help anyone can offer will be greatly appreciated. This is fairly critical, as I have no failover box, and am out of ideas for what is causing this.

How i should make a databases replication ?
Hello thanks before all, i've have a mysql 3.22.15 gamma , and 3.22.16 gamma in two Solaris on Sparc ( SunOS 5.7, 5.8 ). This mysql are in a site in "production", and i'd like to join the data bases in another data base in another machine ( solaris on Sparc ). I've installed in this third machine a mysql version 3.23.40 and i've readen about replication in mysql web. I've readen that if i want to replicate i must have minium version 3.23.33 in all machine's, and activate a log binary in all mysql's. I belive that i should "upgrade" the oldest database first, and then activate the binary-log in this , later , activate binary-log in the third data base ( 3.23.40 ), and then if i copy all databases that exists in the first two machine's ( mysqldump or copyng all data directoris ) , without stop it , and put it into the new mysql's machine , i can do it. I understand that log-binary only log update or delete's , and if i do it i'll be able to do it. The asks are , How i should upgrade of two new database's ?, install a new mysql version in another path ( for example if it was installed on "/usr/local/mysql", the new on "/usr/etc/mysql" ?, Can i install it on the same path and all the database existents will remain intact ? of course i'll do a backup before do something Can anybody help me ? thanks - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Does anyone know why fetchrow_hashref failed?
Hi,
I am using mod_perl and MySQL 3.23.38 on Red Hat Linux
6.2 and my following codes occasionally got an error.
$SQL = 'SELECT col1,col2 FROM table1'.
' WHERE keya=1 AND keyb=2';
$STH = $DBH->prepare($SQL) || die $SQL;
if ($STH->execute() >= 1) {
$rec = $STH->fetchrow_hashref;
$STH->finish();
}
The error was:
DBD::mysql::st fetchrow_hashref failed: fetch()
without execute() at program-name line .
It only happened once in a few dozen transactions. If
anyone knows the cause of this and knows the solution
for it, please let me know.
Thank you very much in advance.
Truoc Duong.

Yes, there are always many ways to do things - but before I give another, I'd really like to hear about the kind of task at hand here. For example: how often do you need that, how much data is transferred, what about the skills of the person who is in charge, can it be done manually at all, etc. I think it is good to ask about the cost of a solution in terms of time and effort and (therefore) money.

Re: Encryption of Data
Contact your ISP and ask them if they already have and/or are willing to set-up something for you. Here's an instance. One host I have used before is TierraNet. They use cron to run a CGI script, named crontask.cgi, at 3AM. You can put anything you want to in that script (Perl, C/C++, etc.) to work with MySQL. So, maybe you could see if your ISP will do something like that. If that's not the case, and if your program is not intended to be publicly distributed, you could just run the CGI script manually. Or, (just another option) if they support SSI you could create a SHTML file with some system commands to do it. And lastly, PHP works wonders. If they don't have PHP installed then you're using a bum ISP, IMHO. :o) Unfortunately from the web, the file permissions have to set to publicly read and execute. So, set-up some sort of password protection (.htacess maybe) or anyone will be able to run the CGI script.

I have experienced very little (almost no) corruption with any of my mysql tables using various versions of mysql for extended periods of time (the times the tables were corrupted it was user error). First thing I would recommend is for you upgrade to mysql 3.23.41, and then try you application again to see if the corruption continues. If it does, send a message back to this list with more information reguarding your setup (OS, hardware, mysql compile options, ect.. ). Then perhaps we can help find the cause of your problem. ryan > These are some remarks on mysql(3.23.32) with regard to > my experience > with data crash and recovery.

Column permissions bug on Win98...and workaround.
I had trouble learning column permissions on Win98 because a possible bug got in my way. I think that there is a problem with the tables_priv part of the user verification. According to mysqld, I am using "Ver 3.23.39-max-debug for Win95/Win98 on i32" of the program. I submit this bug because I didn't read about it in my hour of searching through the mysql mailing list archives. Here's how I reproduce it on a database UN where user search@localhost has usage permissions on *.*: As root, from within UN: 1. create table Test (Trial int, Trib int) 2. insert into Test values (3, 4) 3. grant select (Trial) on Test to search@"%" As a user, from within UN (in my case, search@localhost): 4. select Trial from Test That caused MySQL to tell me that I had no select permission for the table 'test'. However, if I go back to my root session... 5. update mysql.tables_priv set table_name="test" where table_name="Test" and db="UN" 6. flush privileges ...and go back to my query as [EMAIL PROTECTED] 7. select Trial from Test ...everything works fine. I can select the column "Trial", but selecting column "Trib" will correctly throw a column-select error. I have taken special care to make sure that I typed table and column names with the perfect case sensitivity, as if I was using MySQL on a *nix platform. I apologize for not using the mysqlbug script mentioned in the documentation. I've been using MySQL for only 5 days, and this problem has made my head spin a little bit. Also, I think this bug is the reason that something like 'grant select on UN.Test to search@"%"' doesn't work for me, but 'grant select on UN.* to search@"%"' does work. Michael L.

Re: Query optimization issue.
> > mysql> explain select * from dominf.domip order by ip desc; > > 'ORDER BY something DESC' does not use an index. It must > be ascending. See the manual. Also, I forgot, if you do this often and it needs to be in DESC order, you can always alter the app to create and use an extra column 'ip_desc unsigned int not null' and set it in an insert to (0x - ip) and have an index on ip_desc. (If the column was signed you would use 0x7FF - thevariable, but ip numbers need to be stored as unsigned). Sincerely, Steven Roussey http://Network54.com/?pp=e PS: I'm trying to set aside a week in September to augment the MySQL code to use an index even with DESC in these situations. MySQL AB has some unfinished code to do this that I'm working from.

Re:MySQL Bug
Chris, mysqld.exe in version .38 was accidentally compiled with __NT__ defined.

The above statement still doesn't return any result. However, if I change it to as follows, it will return results: select subject,subhead,subsubhead,data2,data3,see_also from npl_detail where (subject like '% asia %' AND subject NOT like '%winter%') OR (subhead like '% asia %' AND subhead NOT like '%winter%') OR (subsubhead like '% asia %' AND subsubhead NOT like '%winter%') OR (data2 like '% asia %' AND data2 NOT like '%winter%') OR (data3 like '% asia %' AND data3 NOT like '%winter%') OR (see_also like '% asia %' AND see_also NOT like '%winter%') ORDER BY subject, subhead, subsubhead desc limit 0, 15 Logically, there is no difference between this and the one you gave me.

master.info and my.cnf updates
I just set up a master/slave replication scheme and all is well, but through the procedure did get bit on the tail. After the setup, and after the master and slave mysql servers had been started, I got some error messages that pointed to a type in the slave's my.cnf file. I shut the slave down, fixed the typo, and restarted. Got the same error. I had a look at the master.info, and noticed it contained old information from the previous my.cnf. There were no binary log entries in it, so I shut the slave down, deleted the master.info, and restarted the slave. This fixed the problem and they're replicating fine. (A terrific feature, my thanks to the mysql team for that one.) Question is, is this behaviour by design? Seems to me if you edit my.cnf and restart the mysql slave the master.info entries corresponding to the my.cnf file should be updated. Thanks for any insight.

Redundancy within rows
Being a newbie to database design, I wonder if those more experienced could give me an opinion on what constitutes "good practice" - as opposed to what is technically possible. I know what I want to do is technically possible, but am I lining mself up for trouble by doing it? I know that it is a good database design never to have a particular datum more than once in the database, and to construct views of the database using Joins. I interpret this as a general invocation against redundancy. However, I want to used some redundancy within a row, and wonder if this is regarded as a bad idea. I have three data: start, finish, and length, and I may want to search by different combinations of them Obviously, these are redundant: length=finish - start. If I choose to store start and finish, I can obtain them in (say) length order by doing SELECT (finish-start) AS length from table ORDER BY length ; and obviously I an do the reverse calculation if I choose to store start and length. However, this involves MySQL in doing significant calculations as part of the search. Searches will obviously be faster if it doesn't have any calculations to do - I can even index by length, making the searches much faster again. But I don't have any feel for how much faster. I can easily afford the disk space for the extra column. Things that make the redundancy less dangerous are: All inserts will be done by one application (well, today) and can therefore be funnelled through one routine There are no updates (again, as of today) Is this a reasonable thing to do, or a bad idea?

mysql parsing hex to make an ip address
Hello, I am trying to convert a hex number that is stored in a mysql db into an ip address. Here is my problem: I can convert the original integer into a hex number like so: For example: mysql> select distinct HEX(ip_src) from iphdr; --- |ip_src| ---| |80B7EB99 | |-- Now, I need mysql to parse the hex number and then convert the parsed data into base 10. For example: 80B7EB99 (hex) = 128.183.235.153 to convert the hex into the ip address, we need to do this: 80 (hex) = 128 B7 (hex) = 183 EB (hex) = 235 99 (hex) = 153 so I need mysql to parse the hex number into 4 parts, convert each part from hex to base 10, and then add a "." between each base 10 number. I know how to do this in perl, but I was wondering if it was possible to do strictly in mysql. I really hope so because it would help out a lot. Any help would be greatly appreciated, -jamil Jamil D.

SELECT answer time
I´m converting an old DBF aplication to MySql an I´m having a very strange problem. When I first execute a query it takes from 12 to 30 seconds to have an answer, after that it runs in about 2 or 3 seconds. It´s a very large file (ZipCodes) and I must seek by ZipCode, by State/City/Street (where the problem occurs) or by State/Street (not so important) In a first step we are using MyODBC (the programs are still in Visual Fox) afterwards they will be converted to another language. the whole line is something like that SELECT * FROM cepect USE INDEX (cepect1) WHERE state="SP" AND city="SAO PAULO " AND LEFT(street,6) = "ESTELA" ORDER BY uf,cidade,logradouro comments : cepect ==> file name cepect1 ==> index name (ordered by uf,cidade,logradouro) we use LEFT because I need all streets with that begins whith that name we had to put the order clause because it was retriving in another order (why the output isn´t in the named index order ?) Well that´s the problem.. Other considerations : - I´m an old guy... - I´m used to control my whole file (dbf, c-tree, and so on) - I´m from the time that develloper´s had to knew what they wanted and mastered the whole file The old program used a grid and the pointer just skip to the first record that matched the desired key, so the user could look around and choose the desired record (In that case it´s really a good feature) The question is don´t you have direct acess routines where I could : - "find" or select a record passing a key (an old find/seek command) - "skip" records (on both sides using the actual index of course) - retrieve records these records Or in one line : - direct access and control to files for productivity programs in another line : - may I skip SQL processor... If you can explain me the first problem I´ll be pleased, the job is for a courier and this query is one of the main ones (and more used) The other questions are just ..., well probably there are other developers that know exactly with record must be updated and need speed...

RE: Installing on Linuxppc???
Hiya, Yes, when you install from an rpm you just get the server, so you need to download the client programs binary in a seperate rpm and install them too. Also, the rpm decides where to install everything so you don't actually end up with a base install dir for MySQL.

Installing on Linuxppc???
Hi all, Brand new to this list. I have MySQL running happily on my NT laptop. I decided it was time to migrate to Linux so I have set up an old Mac (nubus) with Linux-PPC-2000Q4 and have tried to install MySQL with varying degrees of difficulty. After some very futile attempts at a source compilation due to mising headers I have downloaded the version 3.23.27 ppc.rpm and rpm -i'd it. I now see that the daemon is indeed running but I have no control over it. There is no mysql folder outside the /var/bin/ folder so I cannot set up passwords or create databases etc. Can I just add a client to do this for me (if so where do I get it and how do I install over the daemon?) or is there another package which I should install to replace the one which is running (how do I stop it without any control?)

Solaris JDBC
Sir, I was able to successfully use the JDBC driver to connect from a Linux computer to a mysql database resident on another computer running Linux. The Linux computers are running Java Version 1.1. I am now trying to use the same JDBC driver to connect from a Sun Solaris 8 to a Linux computer containing mysql. The Sun computer is running Java Version 1.2.2. I get the error 'No suitable driver'. What is the problem? I created the CLASSPATH as before and placed the driver in /usr/local/mysql/mm.mysql-2.0.4-bin.jar. Any help will be greatly appreciated.

experiences with table corruption-should this be in a faq?
These are some remarks on mysql(3.23.32) with regard to my experience with data crash and recovery. It is not meant to be negative in any sense and I am actually very thankful there is a database like Mysql around. On the other hand, if these experiences are not due to some mistake on my part and if my workarounds are reasonable, it might be worth including them in some documentation of faqs. First, it is fairly EASY to get table corruption . I am using a perl/DBI script to parse some data files and store them in Mysql tables. It looks like it is a little safer to close the Database handle before attempting say a mysqldump. To optimize queries I am storing the data in tables according to some attribute. For example if this were a grocery shop inventory, the tables would looks like: Table: Bananas item_no quantity price Table: Oranges item_no quantity price etc.. This is because I have a lot of data and I am mostly interested in issuing queries on each species separately. Needless to say, this creates a very large number of tables(more than ls or rm can handle at a time and of course also more than what myisamchk can repair in a shot) I have found that if DBI dies for some reason, then there is an almost certainity that at least some tables are corrupted. In most cases myisamchk is able to only recover part of the records (from 50 to 80-90%) For recovery,the perl script uses a system call to mysqldump every N files that are parsed. Unfortunately, this gives some problems too. Sometimes mysqldump does not complete and sometimes even though it completes, one cannot subsequently recover all data because mysql ... http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

Just create an "unique index" on these fields (arena, time, date, sid).
See 'alter table' command in MySQL manual.

Re: 4 fields to form key
I am not sure about the primary key.
You can create a UNIQUE index on (field1, field2, field3, field4)...
(I have done this)
This will prevent any duplicate rows from being inserted.
Hope it Helps,

4 fields to form key
Hi
Is it possible to use 2 or more fields to become the primary key. I have a
table
CREATE TABLE tmptraining (
rowid int(10) unsigned NOT NULL auto_increment,
sid char(32) NOT NULL default '',
expiry date NOT NULL default '-00-00',
arenaid tinyint(1) unsigned NOT NULL default '0',
time time NOT NULL default '00:00:00',
date date NOT NULL default '-00-00',
equip enum('Y','N') NOT NULL default 'N',
PRIMARY KEY (rowid)
)
and I want to constrain the information on four fields; arena, time, date
and sid. That way if someone clicks the refresh or reload button it will
not add another row, if all FOUR of the fields have the same value as
another row. Is there a way to do this?
Thanks
Tim
