Re: go back machine
An example, which use a subquery (available from MySQL 4.1): select eqid, paramid, lastmodified, value from eq_deltalist param1 where lastmodified = (SELECT max(lastmodified) FROM eq_deltalist WHERE paramid = param1.paramid AND eqid = param1.eqid AND lastmodified = now()) You would probably want to join the outer of the two queries with eq and eq_params also Regards /Karlsson Niklas Karlsson wrote: I'd like to setup an application to store equipment configuration data in a MySql database. The basic setup is that each equipment has a certain number of parameters which may change over time. I'd like to track these changes over time and want to be able to create queries which determine the status a certain date. I guess the easiest approach is to have one column per parameter and simply store the value of all parameters whenever I read up the configuration data using the Equipment Id and Date as keys. However, I'd like to store only the delta information, I.e. data changed between different dates. To give an idea, I need to be able to track around 100 parameters for roughly 1 different equipments so performance is an issue. Assuming now I create the following tables; CREATE TABLE `eq` ( `eqid` int(11) NOT NULL auto_increment, `eqname` char(10) default NULL, PRIMARY KEY (`eqid`) ) CREATE TABLE `eq_params` ( `paramid` int(4) NOT NULL default '0', `paramname` char(10) default NULL, PRIMARY KEY (`paramid`) ) CREATE TABLE `eq_deltalist` ( `eqid` int(4) NOT NULL default '0', `paramid` int(11) NOT NULL default '0', `lastmodified` datetime NOT NULL default '-00-00 00:00:00', `value` double(15,3) default NULL, PRIMARY KEY (`eqid`,`paramid`,`lastmodified`) ) If I define my equipments in eq, the different parameters in eq_params and each change of given parameter in eq_deltalist, how do I query for the valid parameters a certain date (i.e. when the lastmodified date is closest to the date in question) ??

Re: why aren't my PRIMARY KEYs being used?
I disagree with your LEFT JOIN/RIGHT JOIN results. SELECT activenodes.name,lrsrc.lid,activelayers.rsrcc,lrsrc.rsrc,nrsrc.rsrc FROM activelayers LEFT JOIN lrsrc ON lrsrc.id=activelayers.id AND lrsrc.lid=activelayers.lid RIGHT JOIN nrsrc ON lrsrc.rsrc=nrsrc.rsrc RIGHT JOIN activenodes ON nrsrc.id=activenodes.id ORDER BY activelayers.lid DESC; Since you RIGHT JOINed nrsrc and activenodes to your query, neither your 1st nor your 5th columns should contain any null values. So, the columns that could contain null values are the 2nd, 3rd, and 4th (as both activelayers and lrsrc are optional tables However, only your 2nd and 4th columns contain nulls. So, where are the optional (non-matching) rows for column 3? Where are those null values? There should be nulls there for everywhere you have a null in columns 2 and 4, right? ...OR... Are the tables activelayers, nrsrc, and activenodes participating in a Cartesian product and only lrsrc is actually optional? Which method of looking at this query is correct? Can you be certain that the same style query will respond with the same decisions about which tables are optional and which ones aren't (because of the mix of LEFT and RIGHT joins in the same query)? The only way to avoid this kind of order-of-operations dilemma is to use parentheses to group (nest) your joins so that they evaluate in the correct order. However, last time I checked, that is still on the TODO list to fix. http://dev.mysql.com/doc/mysql/en/TODO_sometime.html (see third from last) So to get back to the original issue. To recap: from http://lists.mysql.com/mysql/174702 snip Conceptually, here's what I'm trying to do: I've got a set of tasks to execute (frames). The frames which are ready to execute are in wait mode. These frames are associated with layers (in the table layers), and these layers have 0 or more layer resource requirements (in the table lrsrc). I also have a table of compute nodes (nodes). Each of these nodes has 0 or more node resources (in the table nrsrc). If a layer requires linux and perl resources, frames in that layer will only run on compute nodes which have linux and perl resources. snip What was the question are you trying to answer? I know it was something about matching layers and nodes but I am not perfectly clear on what results you wanted. I really do want to help and I don't want to argue over what I think is a bug (or an under-developed section) in the program. You may have received the results you wanted this time but I am not confident that this query is correct for the question you are asking nor am I confident that it will continue to return correct results in the future.

Note, I know this could be easily accomplished in the program instead of MySQL, but it's always a challenge to see how much I can stuff into a single query. -- Ryan Sommers [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Disincluding columns when using load data
I've checked through the archives a documentation but cannot find an
answer to my problem. I'm attempting to load data from a text file
that has a column that is not present in my database table.
Table
B C D
File
A B C D
I've been trying to find a way to ignore the first column of the text
file by specifiing columns like:
(Null,B,C,D) or ('',B,C,D) but mysql doesn't understand these
commands. Is there a way to ignore columns with load data?

Updating rows from a query
I am using the C API with MySQL 4.0.17 on QNX 6.2.1b.
I want to update the rows that are returned as I get them. Is this
possible. Here's a simplified version of what I am trying to do:
query = select seqNo, priority from packet where timestamp now() -
interval 15 second order by priority desc, timestamp;
mysql_query(mysql, query);
result = mysql_use_result(mysql);
while (row = mysql_fetch_row(result))
{
seqNo = atoi(row[0]);
priority = atoi(row[1]);
sprintf(updateStr, update packet set timestamp = now() where
seqNo = %d, seqNo);
mysql_query(mysql, updateStr);
}
However, when I do this, I get:
Commands out of sync; You can't run this command now
Anyone have any ideas on how to to accomplish this?

Of course, maybe that's what you were saying in your original posting. Try checking the permissions of /var/lib/mysql or wherever it said that the socket should be in that error message. ls -l /var/lib/mysql It should show that the owner of that directory is mysql.

Utf8 collations
All of the unicode collations listed in the reference manual except the binary collations are not sensitive to diacritical marks. That is, if I do the following: create table t ( filename varchar(260) ) type=InnoDB CHARACTER SET utf8 collate utf8_unicode_ci; -- insert an e-acute insert into t values ( x'c3a9' ); mysql select * from t where filename = 'e'; +--+ | f| +--+ | é| +--+ The problem is that e really isn't the same as e-acute for the file system. Ideally, what I want is a collation that is case insensitive, but is sensitive to diacritical symbols, but a case sensitive collation would be okay if it were sensitive to diacritical symbols? Is there none available for utf8 as the manual indicates? If not, how difficult would it be to develop one? I am using 4.1.3 on Mac OS X. Brooks R.

I hope there's a solution for this. -- For technical support contracts, goto https://order.mysql.com/?ref=ensita This email is sponsored by Ensita.NET http://www.ensita.net/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Gleb Paharenko / /|_/ / // /\ \/ /_/ / /__ [EMAIL PROTECTED] /_/ /_/\_, /___/\___\_\___/ MySQL AB / Ensita.NET ___/ www.mysql.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: How can I store Images in the MySQL Database
Hi Nikhil, Have a look at www.hotscripts.com for either a script that dose this or a tutorial to show you how to do it. But in general you DO NOT store the image in a MySql table you just store its location name i.e. 'images/image1.png' and then with a select statement use the result in a 'img src' string for your script. Here is another place to start for a PHP example but there a loads for other scripting languages. http://www.zend.com/zend/tut/photogallery.php I hope that helps Dave Carrera -- UK Web Hosting @ http://www.ephgroup.com -Original Message- From: Mulley, Nikhil [mailto:[EMAIL PROTECTED] Sent: 02 November 2004 05:05 To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: How can I store Images in the MySQL Database Hi Lists , My Query is How Can I store Images in the MySQL Database , and how to Index them , can anybosy help me on this please I am starting out a Online Photo Gallery and want to share them , and I want to make the search available, Does anybody has already done on this ?
