AW: Subselect or other way?
Thats right... But I don't want all id's with nr=123 or nr=456. I want all id's with nr=123 and nr=456 and only these id's. For Example: id nr --- 1123 1 456 1 678 2 457 2 897 2 123 3 123 3 678 3 456 Id 1 and id 3 have only both numbers. If I try your query i become id 1,2,3 and that's not that i want. I want only id 1,3 regards Micha -Ursprüngliche Nachricht- Von: Jonny Stendahl [mailto:[EMAIL PROTECTED]] Gesendet: Mittwoch, 22.

Re: MySQL InnoDB startup problem
David, did you upgrade from a very old version of MySQL to .49? The sorting order of latin1 accent characters was changed about 8 months ago, and that may cause the assertion you have encountered. You should dump and reimport your tables if you have accent characters. Anyway, the B-tree index is now corrupt. Please use the instructions of section 6.1 in http://www.innodb.com/ibman.html to force recovery. Then dump + drop + reimport.

Re: InnoDB, possible bug?
Andrei, this is probably not a bug in InnoDB. In theory, 4000 random disk seeks would use more time than scanning the whole table of 700 000 rows. The optimizer was tuned .48 (not yet in 4.0.1) to favor index searches over table scans. That may solve the problem here. On the other hand, the fact that MySQL refuses to use the index specified in the USE INDEX clause may be a bug. I have forwarded this email to MySQL developers.

Having problem installing.
Yep, I'm a n00b, or whatever you want to call it. I'm having a problem installing MySQL version 4.0.1-2 (or any other version for that matter). I'm starting a rather large project where our funds are limited and we want a high performance database, so we chose to go with MySQL. Since we need functions that are only in version 4.0.x (actually we will need functions that are only going to be in 4.1, but we can wait for most of those for now), I've been trying to install that. Originally in RedHat 7.1, then 7.2, then 7.3. None of the installs that weren't default (with the OS) have worked yet. I never actually checked the 3.x versions that installed with the OS, so they may have not worked either though. The error that I commonly get (only see errors when I try manually installing it, otherwise it gives me no errors, but it just doesn't work) involve resolveip (can't lookup localhost.localdomain with resolveip or something like that). I've followed the directions from the website, other websites and even in the "MySQL & mSQL" book by O'REILLY and no matter what directions I follow, I end up with the same problem, can't connect to the db server, even from the db server (let alone one of the other Linux boxes on the network or one of the Win* boxes on the network). Any ideas? Other than RTFM, I've done that and can't seem to find anything related to the problem that I'm having. Server setup: Dual AMD 1600+ OS: openMosix/RedHat 7.3 (currently) for AMD SMP eth0: DHCP (192.x.x.x) eth1: static (10.x.x.x) If there is anything else that you might need to know, I'll post that information also, I figure that this is probably the information that is relevant and I'm trying to keep this under my standard 'novella' that I write in e-mails.

Re: SQL query
This seems like a fairly straight forward and simple query, however you run into the max row information problem as described in the manual at http://www.mysql.com/doc/e/x/example-Maximum-column-group-row.html Finding the first part is fairly easy and straight forward, it is just getting the price at the same time as the other info where you run into that problem. Here is the query I wrote using the max-concat trick as described at the bottom. It would be simple to use the temp table one as well. select tbl1.timestamp, left(max(concat(lpad(tbl2.timestamp,8,'0'),tbl2.price)),8) as timestamp, tbl1.code, substring(max(concat(lpad(tbl2.timestamp,8,'0'),tbl2.price)),9) as price from tbl1, tbl2 where tbl1.timestamp >= tbl2.timestamp and tbl1.ordertype='N' and tbl1.code= and tbl2.code= group by tbl1.timestamp; That should give you the results you are looking for. As for speed the temp table one might be faster depending on the number of rows you have and such. You might want to do some testing to find out. The reason we don't need to use the concat trick on the tbl1.code in the select string is because that is specified in the where clause and can only be that singular value. On a different topic, does anyone know if it would faster to use the "tbl1.code = and tbl2.code = " or to use "tbl1.code = and tbl1.code=tbl2.code"? I've always assumed it was the first, but depending on how the query processor works I could see the second one being faster. If anyone knows for sure, feel free to help me out, Thanks.

RE: Evaluating a String
I think I will describe the problem in detail.
I using Container-Managed Persistence (CMP) beans in
J2EE RI 1.3. I will like to specify the SQL for one
of the finder methods to be:
SELECT * FROM table1 WHERE ( ? )
This is to faciliate me manipulating the WHERE clause
b4 sending it as a string into the finder method.
I THINK the J2EE sever will insert the string (say
table1.field1=0) into the SQL as
SELECT * FROM table1 WHERE ( "table1.field1=0" )
and NOT
SELECT * FROM table1 WHERE ( table1.field1=0 )
The latter is the correct syntax, note that there's NO
SINGEL/DOUBLE QUOTES on the string and this is what I
want to achieve. I'm wondering if there's a function
that allows you to do something like this:
SELECT * FROM table1 WHERE (
function("table1.field1=0") )
will give you
SELECT * FROM table1 WHERE ( table1.field1=0 )
TIA
Ho Keat

Re: Query help
Here is a query that will do what you want I think: SELECT count(distinct goal.id) as ours, count(distinct goalopp.id) as theirs, game.id FROM game LEFT JOIN goalopp ON game.id=goalopp.game LEFT JOIN goal ON game.id=goal.game GROUP BY game.id HAVING ours > theirs; We have to use a having statement to compare the number of goals since count() is an aggregate function. They can't be computed as part of the where clause as the where clause determines which should be counted in the function. Left Joins are needed in this case because it is possible that there might be 0 goals or goalopp for the game, in which case we still want the number (which would be 0). Hope that helps you understand some of the logic behind why the query has to be this way.

Cross-platform Deployment issue.
Hi, I have an application in Java that access MySQL databases through JDBC. The issue is that I have to be able to move the database files across different platforms (Windows, UNIX-Solaris, UNIX-IBM, UNIX-HP). If I go to the manual, MySQL says that the database files are compatible between computers with the same floating-point format. What is this about?

Well, first you've got to get the file onto the local server. In PHP, you can use fopen() together with other functions to get the file from the user's machine onto the remote server. But I'm not sure you absolutely want to store it in the database. - 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?

Cross-platform Deployment issue.
Hi, I have an application in Java that access MySQL databases through JDBC. The issue is that I have to be able to move the database files across different platforms (Windows, UNIX-Solaris, UNIX-IBM, UNIX-HP). If I go to the manual, MySQL says that the database files are compatible between computers with the same floating-point format. What is this about?

Re: my.cnf
On UNIX and Linux machines, there are a few places that MySQL will look for your my.cnf. The are detailed at: http://www.mysql.com/doc/O/p/Option_files.html However if none of these files exist, then MySQL will use the default values assigned for all neccesary settings. You can then just create the option files using your preferred text editor and next time you restart mysqld it will use those new values you specified.

Query help
I can't seem to properly wrap my brain around left joins. If anyone knows of a good tutorial somewhere, I'd appreciate it. That having been said, I was hoping someone could help with this query I'm trying to do as I've been horribly unsuccessful. 3 tables: goal (own goals), goalopp (opponent goals), game Pertinent fields: goal.id goal.game goalopp.id goalopp.game game.id One game record for each game. One goal record for each own goal, one goal record for each opponent goal, each with a unique id in their table (goal.id, goalopp.id) and a reference to the game id (goal.game, goalopp.game). What I'm trying to do is get the number of games where the goal count is greater than the goalopp count for a set of games. Of course I could just loop through an array for each game, but I was hoping to do it with a single query. So what I'm getting at is essentially select (count game) where ((count goal) > (count goalopp)) for each game where game.something='whatever' Help would be greatly appreciated.

Re: Inserting images and other blobs
There is a function called Load_File which will cause the mysqld to read the file into a field. It is designed for such things. Check out http://www.mysqldeveloper.com/faqs/index.pcgi?id=7 for more information. Keep in mind that generally it is better to use the file system to store files and the database to store data. The preferred way to do this with images is to just keep track of the name and location of the file in the database. Good luck with your application.

Re: Error 1030: error 127 (table handler)
We've been seeing this quite often at our web application company. The development machines run debian linux with kernel 2.4.x (they differ) and ReiserFS, and on local installations of the web app, which puts DB, web server, and CGIs on the same box, we see frequent table corruption. Sometimes it's on the order of a couple of times a week, which is absolutely ridiculous considering how little the DB install is stressed on developer boxes. Fortunately the DB server used for the public cluster, which gets its own debian linux 2.4.x machine, and I *think* doesn't use ReiserFS (the maintenance crew has changed its collective mind several times, much to the annoyance of the development and QA teams), does *not* exhibit this problem, or so the crew claims. (Don't even ask about the politics of communication within our company...) This is clearly a BIG BIG worry for me, but the story I am handed (from some very dubious sources) is that it's an interaction between MySQL and ReiserFS and that as long as the public servers don't user ReiserFS we'll be fine. Can anybody actually lend credence to this claim? -rob On 21/5/02 at 2:49 pm, Matthias Jaekle <[EMAIL PROTECTED]> wrote: > Hello, > > approximatly twice a week I get Error 1030: error 127 (table handler) on > one table.

Dear All, I have a table contains airline ticket prices, and I want to get the following data from this table The first 5 records of the lowest price of each airline from each city, and don't want to get a duplicated combination of (airline, city) in this result (even if I didn't see all airlines or all cities, I want to see only five records).

Re: returning top two values
Not a problem. I think the easist way to do it is SELECT * FROM families ORDER BY score DESC LIMIT 2 Of course you need your grouping statement in there but the ORDER BY section shouldntmake a difference. There are MAX and MIN functions but my understanding is that those will only return THE highest/lowest values and not say the highest two values. It would work Ibelieve if there were two families with the same highest score. Someone correct me if I'mwrong. -Nick > Hi, > I have a table containing data on a number of families. > > I want to retrieve members of each family that have the two highest > scoring values for a column. i.e the max and second max. > Is there a function similar to max() or greatest() that will return the > top 2 values when grouping by family ID? > > I can do this using perl in about three steps but would rather make > life easier for myself if I can. > > Thanks in advance > Rich > > mysql query > > > - > 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 To > unsubscribe, e-mail > Trouble > unsubscribing?

This is wrong. You can't define a variable _after_ you attempt to use
it in a function.

As you mentioned, the problem here is that he is lacking support for
mysql in his PHP build.

Error 1030: error 127 (table handler)
Hello, approximatly twice a week I get Error 1030: error 127 (table handler) on one table. This table is around 2.3 GB, the indexfile around 2.2 GB. There are around 24.000.000 records in the table. I am running mysql 4.0.1-alpha on linux with 2.4.18 kernel. But I also got this error with older mysql versions (3.23) and kernels. Sometimes restarting mysql solves the problem, sometimes I have to check the table to get back a running system (no errors found) and sometimes I had to repair the index or data file. But I can not find any schema. Checking and repairing tables take multiple hours and stops our normal work. So it is very bad. Does anybody have an idea, how to solve this problem ? Does somebody else have problems like this ? Could there be misconfiguration responsible ?

Re: MyISAM internal algorithms
Ok, so know you got me interested. What exactly are R-Trees. I know the structure of B trees, hadto program a small version of a B' tree before, but never heard of an R-Tree. Any explanation or link to where I might find some info would be appreciated. -Nick > On Mon, May 20, 2002 at 09:39:52AM -0600, Andrei Cojocaru wrote: >> >> I believe mySQL uses B-Trees (not binary trees), that's about all I >> know :) > > Right.

David, get the manual, look at the JOIN command. You have to LEFT JOIN the table to itself on the condition that t2.id = (t1.id - 1) that looks like: SELECT ANY_FUNCTION(t1.st, t2.et) FROM mytable AS t1 LEFT JOIN mytable AS t2 ON t2.id = (t1.id -1) WHERE ... This gives you access to the columns of two subsequent rows and you may process the data as you like. I did not test this, but it should work. For the first row, as expected, all columns of the right table t2 are set to NULL.

Re: Mysql Client
Do you mean, a character client for windows or the linux client?

Re: HOWTO: diffs between rows.
You could join the table against itself, matching each row against every following record and then summarizing to find the "next" one. If your table is of a fair size, you'd need to play with the optimizer to make sure you get the efficiency you need. The SQL would be along the lines of: select max(curRow.id), time_to_sec(min(matchedRow.st)) - time_to_sec(max(curRow.et)) from events as curRow, events as matchedRow where curRow.et <= matchedRow.st group by curRow.id On 21/5/02 at 10:43 am, David Shields <[EMAIL PROTECTED]> wrote: > Probably a very simple one for you guys, but I'm stuck. > Given a simple table (events): > idint > sttime not null > ettime not null > > I know I can get duration by converting st and et to secs and subtracting > (that bits easy), but how would I go about getting the gap between > successive records IN MY SQL STATEMENT (without processing the result set > in my application language (php)): i.e. > idst et > 1 09:00 10:00 > 2 10:15 10:45 > 3 11:45 12:00 > > i.e. my result wants to be (assuming data is good, and sort by st) > > idst et gap_since_last_row > 1 09:00 10:00 0 (no prev row) > 2 10:15 10:45 0:15 > 3 11:45 12:00 1:00 > > I suspect I should be using SQL variables, but docs seem a bit opaque. > > Anyone point me in right direction ? > > David. > > - > 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?
