RE: Getting mysql up and running on Mac OSX
Well the @INC is the enviroment array of perl so the perl script you're running needs DBI.pm perl module that appears not to be instaled on your box you can find more info about on http://dbi.perl.org/index.html and you can get it on http://search.cpan.org/author/TIMB/DBI-1.30/ -jose I've gotten mysql server running but am getting lots of errors when I try to run any of the scripts that come with it. for example when issuing the following command. [HDSK-Laptop:/library/mysql/sql-bench] haridass# ./run-all-tests The result I get is: Can't locate DBI.pm in @INC (@INC contains: /System/Library/Perl/darwin /System/Library/Perl /Library/Perl/darwin /Library/Perl /Library/Pe rl /Network/Library/Perl/darwin /Network/Library/Perl /Network/Library/Perl .) at ./run-all-tests line 36. it looks to me like @INC is not pointing to the correct directory. I'm a pretty decent C++ programmer but haven't done much with using the command line. Any tips on what is wrong or where to go from here. i have the SAMS teach yourself mySQL but of course it is not at all Mac specific. Any help would be appreciated. === Hari Dass S.

Select statement paramter
Hi guys, I was wondering if anyone knew of a paramter that can be put on the end of a select statement when querying a table which only pulled out one unique record based on a field. I.e If i had a drink database and in it were 10 cokes 10 fantas 10 pepsi's what select statement would i need to pull out 1 coke,1 fanta,1 pepsi .

re: Re: Lost connection to MySQL server during query
Hello Graham, Tuesday, October 15, 2002, 12:03:34 PM, you wrote: 1. replace Red Hat's rpms with MySQL binary release, download it from http://www.mysql.com/ 2. run myisamchk on all files. 3. run MySQL and enjoy the reliability since then :-) GM Why do Linux distributions ship broken MySQL packages? The newly GM released SuSE 8.1 shows similar problems, connecting from the local GM system works fine but the server crashes (and is restarted by GM safe_mysqld) as soon as a remote user attempts to connect. As has GM already been noted, after installing the official MySQL RPMs GM everything works. This is a common problem with non-MySQL builds. Why? First, because compiling MySQL is a very careful job to do, you don't have to miss a single point in instructions. Say, compiling with wrong options will give you a binary that will not be able to resolve hostnames, load data more than 2gb, work with more than a couple of hundreds of connections and so on. Second, because the only stable GNU C compiler today is gcc 2.95. It's true that MySQL cannot be compiled correctly with gcc 2.96 and 3.xx. Third, because making a correct glibc binary is very, very hard goal to accomplish. Not to speak about other binaries, but, say, MySQL works with threads, and the thread stack in glibc should be around 256k for MySQL can handle hundreds of connections. In other case, MySQL will just crash after Nth connection. By default, the stack is 2mb in glibc. This is causing crashes, too. There are a lot of many other reasons. That's (in short) why MySQL official binaries are compiled statically and works well. -- For technical support contracts, goto https://order.mysql.com/?ref=ma02-010c This email is sponsored by Ensita.net http://www.ensita.net/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Egor Egorov / /|_/ / // /\ \/ /_/ / /__ [EMAIL PROTECTED] /_/ /_/\_, /___/\___\_\___/ MySQL AB / Ensita.net ___/ www.mysql.com - 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?

re: re: High load with cleaning up status
Hello Mike, Monday, October 14, 2002, 6:48:36 PM, you wrote: MZ Recently our DB, which is running MySQL 3.23.52, started experiencing MZ intermittant load spikes, of the magnitude of 200+ load averages. Normally, MZ our high spike is about 0.90 load. When this starts happening, we notice a MZ lot of processes cleaning up within the database. Can someone clue me in MZ as to what cleaning up means, and what the possible cause of this is? Sure, we can. Please tell us: - what is the exact mysql version running (build) MZ Version string: mysqld Ver 3.23.52 for pc-linux-gnu on i686 MZ Straight off the RPMs from the MySQL download mirrors. Is it a mysql official binary or just a recompiled src.rpm? You should only use official binaries. MZ memlock - how does the table looks like (structure/type/properties) - what is the hardware MZ Dual AthlonMP 1600+, 1GB RAM, RAID-5 configuration on the DB filesystem. - what are the OS details MZ The session table would be a HEAP, but for the text field. As a compromise, MZ the MYD and MYI files are in /dev/shm. Ok. First, I would move the table to a disk. It's just my guess. I believe, memlock and MyISAM-in-memory may be a cause of a conflict. Another try is to remove memlock option but leave data in ram. Second, let's go thru variables: key_buffer_size Index blocks are buffered and are shared by all threads. key_buffer_size is the size of the buffer used for index blocks. Increase this to get better index handling (for all reads and multiple writes) to as much as you can afford; 64M on a 256M machine that mainly runs MySQL is quite common. If you, however, make this too big (for instance more than 50% of your total memory) your system may start to page and become extremely slow. Remember that because MySQL does not cache data reads, you will have to leave some room for the OS filesystem cache. You can check the performance of the key buffer by doing show status and examine the variables Key_read_requests, Key_reads, Key_write_requests, and Key_writes. So you should definitely lower the value of key_buffer_size (note the spelling change - for other variables, too). I would be suprised if that won't help. -- For technical support contracts, goto https://order.mysql.com/?ref=ma02-010c This email is sponsored by Ensita.net http://www.ensita.net/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Egor Egorov / /|_/ / // /\ \/ /_/ / /__ [EMAIL PROTECTED] /_/ /_/\_, /___/\___\_\___/ MySQL AB / Ensita.net ___/ www.mysql.com - 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?

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked agaist is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong

It is possible that mysqld could use up to
key_buffer_size + (record_buffer + sort_buffer)*max_connections = 225791 K

Hope that's ok, if not, decrease some variables in the equation

Can you use MySQL functionality without MySQL installed?
Hi everyone, Basically my problem is that I want to distribute a program that uses the MySQL C API. The functions mysql_* are available in the dll which can be packaged along with the programs exe. The database that the program uses can also be rebuilt using an sql script so it does not need to be distributed. The manual mentions how to go about connecting to the database but doesn't mention about what to do for a machine that doesn't have MySQL installed. I assume the answer to my question is probably that you have to have MySQL installed but I am just posting this here to be sure. Any information at all on this topic would be appreciated! -Tim - 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?

Dead server
Hello, After upgrading to 4.0.4 from 4.0.2 on three server we have got some mysterious problems with one of the server. Several times it appears to be dead. Connecting takes a very long time, and the CPU load goes throug the roof and beyond. The two other servers runs without problems. The only difference between the servers is that the one with problems is a master for the two others (replicating one DB), and the machine is dual CPU. All serveres run Linux. When the problem occurs I have tailed the slow-log. This crops up every time when there is a problem. I have no idea what it is! # administrator command: Statistics; # User@Host: xxx # Query_time: 31 Lock_time: 0 Rows_sent: 0 Rows_examined: 0 # administrator command: Statistics; # User@Host: xxx # Query_time: 32 Lock_time: 0 Rows_sent: 1 Rows_examined: 70 # administrator command: Statistics; # User@Host: xxx # Query_time: 33 Lock_time: 0 Rows_sent: 0 Rows_examined: 0 I think this statistics command may be what is causing the problems, so can anybody tell me what is happening?

Re: select from multiple tables
Assuming that you're joining data based on colB, you would use: select t1.colA,t2.colA,t3.colA from tblA t1 inner join tblB t2 on t1.colB = t2.colB inner join tblC t3 on t1.colB = t2.colB where... You can alias the table names, but there's really no way to get around specifying the table identifiers in the select portion. If you try selecting colA, it will throw an error because it has 3 colA available to it. Kelly --- Veysel Harun Sahin [EMAIL PROTECTED] wrote: Hello, I have a problem with select statetement.

To combat this I bypassed passwords by creating a my.cnf file. I then have deleted all records in the mysql.user table and am starting afresh. How is the best way to reconstruct this table? Can I add admin@localhost and say a webmaster with access from anywhere? I have looked everywhere for a security guide, can any one point me in the direction of good practice documents?

Re: How many columns does MySQL Support?
I'm not sure what the limit is. MySQL limits tend to be dictated by the OS that is being used. The more columns you have the larger the database file will be. You should try to avoid having many empty columns in a database design, even if you are using varchar instead of char. Try to think ahead in your design to what indexes you will create to speed up searching. You obviously don't want to create 300 indexes (don't know if you even can) and you want to avoid full database searches, which is what happens with no indexes. Going on a relevant tangent here. What could you need 300 columns for? I'd be hard pressed to think of a dataset that would have 300 unique pieces of data. Perhaps you can make your columns into records? A simple example to clarify. I see many database designs that create maybe 10 or more columns to store various phone numbers (home, work, cell, fax, beeper, other, etc.). A better design would be to make them records in a phone number database with a description field to indicate what phone number it is. This gives you the ability to store unlimited phones numbers and to easily search for a phone number (i.e. reverse lookup). Plus, you can create one index to index all you phone numbers for quick searching. I would not split your data into separate tables. If you have to, create a table with a column called field name where you can specify what type of information a record holds.

My task is to insert a new master record and several detail records within the one transaction. There is a foreign key on the detail table set to the unique key (autoinc) field of the master table. Inserting a master record, even with a special field value so that it can be quickly returned with the newly created primary key, so that I might then insert the detail records with this primary key as their foreign key, does not seem very reliable to me (as suggested a few days ago). There must be a more reliable way to do this under heavy traffic. I'm afraid I'm used to being able to grab a generator ID and using that (guaranteed to be unique) for both the primary key of the master and the foreign key of the detail records. Surely there is a good method for use with MySQL?

RE: inserting records
Ok, so I've broken down your problem into small, manageable steps. First, users are provided with a box to enter a value (e.g. pumpkin) and the 1)ability to select a ranking for pumpkin, or 2)the ability to select which old value (apefruit) the new value-pumpkin-belongs above/below (scenarios 1 and 2 are largely the same thing, just that 2 has an extra step so I'll assume 2 is your case) OR they can simply enter a new value (pumpkin) with no rank entry. Pseudocode and logic: Step 1. If the input has no rank entry, get the max value myLocalRanking = select max(colA)+1 from fruitable skip to step 4 Step 2. Find out what value the apefruit has: myLocalRanking = select colB from fruitable where colB = 'apefruit' Step 3. Increment all values in cola greater than or equal to the apefruit value: update fruitable set colA = colA+1 where colA myLocalRanking-1 Step 4. Insert the new value pumpkin with the myLocalRanking value: insert into fruitable (colA, colB) values(myLocalRanking, 'pumpkin') You mention an application so I assume that your application can handle this logic. In general, you could also do it with a stored_procedure/trigger. This solution has some problems to it with multi-user environments and corruption of the data if the process fails part way through. You should be able to mitigate the flaws in my solution by using an autoincremented value for colA (I think) but I'm not that familiar with the MySQL implementaiton of autoincrements, so I'll leave that to you. Also, you mentioned deleting, which would follow similar steps to the above except that you're decrementing everything above a certain value instead of incrementing it. And the final display I'm sure your familiar with as something like select colB from fruitable sort by colA ascending; Hope this helps, Greg sql, query -Original Message- From: kayamboo [mailto:[EMAIL PROTECTED]] I have a table with only one column and values are inserted by getting user request from my application. I want to display the column values in the order they are inserted. So only option is to go for another column with an auto increment key. eg. col Acol B 1 apple 2 orange 3 apefruit But the user should have the option to insert data in between, any two existing column values. He can also delete any record. And now I want to display the records in the new order. eg. col B apple orange jack apefruit - 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?

RE: Inserting Master and Details records
Hi insert_id returns the key value. I use php, and the mysql_insert_id is the last insert_id on that connection, so even if other processes have added new records in the time the script runs the insert_id is the correct one. You can then use that as the key in the detail records.

I've compiled and installed this on my Solaris8/Intel box a few times without a hitch.. I don't recall seeing what version of Solaris you're running.. ? I also compiled with just ./configure - I didn't bother with the other options.. although that might be asking for trouble under certain circumstances... I don't have the source in front of me to check but I seem to recall being able to compile specifically withOUT curses support? Is your ncurses library up to date? Changing which curses libs to use won't affect this issue - the issue is a header/include problem, not a library problem.

Solved the local-infile and related problems
I have solved my problem with MySQL and MySQLdb. The problem was:
I have installed mysql-3.23.52 as part of the Gentoo Linux
distribution. I am accessing MySQL via mysql-python AKA MySQLdb
which calls the MySQL C API. During testing I start MySQL using
safe_mysqld and shutdown MySQL using mysqladmin -u root
--password= shutdown.
When I do a LOAD DATA LOCAL INFILE via MySQLdb, I get the
well-known error message 1148: The used command is not allowed
with this MySQL version.
1. Add to mysql-3.23.52.ebuild the line
myconf=${myconf} --enable-local-infile
It goes in the src_compile() section. Do an emerge dev-db/mysql to rebuild
MySQL.
2. Recompile mysql-python (which contains MySQLdb). I suspect the segfaults
I was having were due to library mismatches. Therefore build MySQLdb after
MySQL.
3. Add local-infile to /etc/mysql/my.cnf in the groups [safe_mysql],
[mysqld], and [mysql]. Do not add it to the group [client].
4. At some point the MySQL GRANT system was changed. Now
GRANT FILE ON my_database.* TO abcdefgh@localhost IDENTIFIED BY '';
does not work. One must use:
GRANT FILE ON *.* TO abcdefgh@localhost IDENTIFIED BY '';
Note that now abcdefgh can access any file on any database. I wish I could
use LOAD DATA LOCAL INFILE is a more secure manner.

load problems on mysql 3.23.52 with and without Max
I'm managing two database servers, one 3.23.52 and one 3.23.52-Max (using innodb tables on that one). They are both running along fine until they suddently start to accumulate a lot of treads (a lot ~= 200-300), the state of these threads is mostly closing and opening tables. This drives up the load to amazing numbers and I'm forced to shut the mysql-server down. Since I'm running these servers in a shared environment I got a lot of users using these servers, and so far I haven't got any grip on whats causing these problems. I got these problems on both servers (one with max and one without), both servers got diffrent users. I've ruled out hardware problems since I get exactly the same behaviour on two independent servers. It would be great if sombody knows the answer to my questions bellow: - is there any know problems with mysql on linux? or with 3.23.52 that should cause this behaviour - what should I do to find the error, my logs shows nothing pecuilar.

one table frozen, rest is okey...
I'm using mysql Ver 11.16 Distrib 3.23.49, for slackware-linux-gnu (i386). Everything was just fine for months, but yeasterday I started to use one of the tables by connecting to it with MS Access 2000. The table has ~10 records. And the strange thing: it was working for few hours (queries, updates, etc.. everything from Access through myODBC 2.50), and then suddenly it frozen! So I checked the server - every table on the server worked just fine. Describe problematic_table also ok. But select * from problematic_table limit 10 : freeze. Select * from another_table : OK. I have no idea why only one table stoped working. I shutdowned the server and brought it up and it is ok now. But what was the reason for freezing the table ? -- ./ premax ./ [EMAIL PROTECTED] - 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?

I use queries like this :

Have you tried building a seperate table of titles for the sake of
having a smaller table to scan through?
SELECT * FROM MyTable LEFT JOIN Titles ON TitleID = Titles.ID WHERE
(MATCH (Titles.Name) AGAINST ('a word')) LIMIT 10;
... I've found this type of optimization helps on large (disk-size)
tables. It helps even more if you make the table like:
CREATE TABLE Titles (
ID int unsigned not null auto_increment,
Name CHAR(150),
PRIMARY KEY (ID),
FULLTEXT (Name),
INDEX NameIdx(Name)
);
(Try both types of index to see if either is faster ... )
Also try putting your 'Autx' fields in a seperate table, for the sake of
good design, then create a cross-linked table to join it to the main table.

RE: about use Dev-cpp and C++
sql, query
But it would be so nice to write:
MySQLConn DB = new MySQLConn ('host', 'port');
DB.Login('user', 'pass');
MySQLTransaction X = new MySQLQuery(DB);
// STL-derived slist:
MySQLResults Results = X.Query(...);
// STL map:
map Row;
while (Results.NextRow(Row)) {
cout ID: Row[ID] , Value: Row[Value] endl;
}
... PS, anyone seen such an API? :)
How about:
OpenDatabase(host, database, user, pass);
OpenRecordset(select * from blah);
while(RecordsetEOF() != EOF)
{
printf(ID: %d Value: %s\n, GetField(ID), GetField(Value));
MoveNext();
}
CloseRecordset();
}
Look for MyC on mysql.com - if you can't find it, email me directly. The most recent
version supports nested SQL, too. The

I had the same problem with 4.0.4, I downgraded to 3.23.52 because I thought it was something with the unstable version. Is 4.0.4 also built against the same static glibc? regards /Lars This problem is due to the glibc used by mysql AB for building binary ... Have a look to mysql 3.23.53 change log : We've hopefully fixed the problem with spurious load spikes on Linux systems when accessing the Database via TCP/IP.

I need to be able to specify the start and end points (i.e. start at 59 and end at 605000) Or do I have to put the query in a for_next loop and let the webserver churn away on it? Thanks.

Re: How many columns does MySQL Support?
From: Andrew Kuebler [EMAIL PROTECTED] 2) Is it just as fast with Mysql to access 10 fields in a table with 10 columns as it would be to access those same 10 fields among let's say 90 other fields in a 100 column table? Are you certain that performance should be your primary concern here? I prefer to design databases with separate tables of tightly coupled information, then LEFT JOIN them as needed. This makes maintenance much easier, and may also be a performance plus, due to locality of reference issues. Only when I'm certain that this form (4NF? I forget) is negatively impacting performance do I bother optimizing to 3NF by permanently joining tables.

Re: Normalization sql
Ooops! You just threw a new wrench into the works! A video may have multiple titles. In this case you must distinguish the original from its presumably foreign-translations (or whatever). In other words, you might store the master as La Cage aux Folles and the English subtitled version as something else, which implies another 1:M table, residing above Titles in the hierarchy. For simplicity let's call it Videos, and then rename Titles to VideoTitles, giving it a foreign key referencing Videos. Thus in the Videos table we have entry 12345, La Cage Aux Folles and in the VideoTitles table we have an entry The Cage of Fools or whatever, with an FK referencing 12345. A title search would then require interrogation of two tables, which in itself isn't terrible since one could UNION the titles from both tables, but possibly this is not the best model. Perhaps the Videos table should contain no Title info, and all that data should be exported to the Titles table. I'd have to give that some thought before deciding. How do I create a junction table? Example, between Genres and Titles, how do I add the to PK fields to TitleGenres? Do I just create the TitleGenres table and add the TitleID GenreID field and does the database know they are linked? The database knows nothing except what is permitted. (Hope Dostoevsky didn't design the database:-) You front end application should anticipate this and present pretty controls for the user. The table TitleGenres implies a reference to both Titles and Genres, so each of these could be presented as a dropdown list, or in a web app you could pass in the PK from the Titles table and have your insert code write the received parameter into the table. (By sticking to Titles rather than shifting the relationship to Videos, you could account for the strange belief in France that Jerry Lewis is funny :-) Creating a junction table is simple. Just add the columns you need and declare them as foreign keys, specifying their reference-tables (InnoDB). If you're using MyISAM tables the responsibility falls entirely on your front end. You may want to modify the Stars table to reference Videos rather than Titles, since the stars remain the same even if you translate the film into Russian or Swahili. hth, Arthur - Original Message - From: John Chang [EMAIL PROTECTED] To: Arthur Fuller [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, October 14, 2002 7:26 PM Subject: Re: Normalization sql Studios (StudioName, StudioID) Genres (GenreName, GenreID) Titles (VideoTitle, Details, StudioID, GenreID, BitRateID, TitleID) Actors (F_Name, L_Name, ActorID) Stars (TitleID, ActorID) TitleGenres (TitleID, GenreID) So, if I just use theses tables I will be OK if the video has multiple titles, multiple actors, multiple genres?

I would suggest for simplicity though that you change the names of your PKs to reflect their table, i.e. Title (VideoTitle, Details, TitleID). Otherwise once you do multi-table queries joins you will have to specify the table names every time. A studio makes zero or more titles (videos). A film belongs to zero or more genres (your answer may be that a film belongs to precisely one genre) A title stars one or more actors (you may plan on storing only one, but how will you decide in a case such as Eight Women?) I would say you need a junction table between Titles and Actors so you can handle multiple stars. I'm not sure what BitRate means but I guess it is an attribute of the Title. Studios (StudioName, StudioID) Genres (GenreName, GenreID) Titles (VideoTitle, Details, StudioID, GenreID, BitRateID, TitleID) Actors (F_Name, L_Name, ActorID) Stars (TitleID, ActorID) If you decide that a Title can belong to more than one Genre, then you need a junction table there too: TitleGenres (TitleID, GenreID) This change would involve removing the GenreID from the Titles table. This design lets you easily find all the titles made by a studio, all the titles featuring a given actor (even if she is the co-star rather than the star), all the titles in a genre and even compound queries such as all the MGM thrillers featuring actor XYZ. hth, Arthur - Original Message - From: John Chang [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, October 14, 2002 8:49 AM Subject: Normalization sql I've read a bunch about normalization in MySQL and still can't do it very well.

Re: Problem with UPDATE table ... can u help plz?
You need to include the field names along with the table name. UPDATE table1 INNER JOIN Table1 ON Table2.FieldID = Table1.FieldID Set Table1.Field1=Table2.Field1, Table1.Field2=Table2.Field2, ...

Hi from Dresden, Germany! I have a littlebig problem: I want to UPDATE table1.fields with data from table2.fields WHERE the id (in this case a product number) is the same in both tables. OK, I did this: UPDATE table1 SET table1.field1 = table2.field1, table1.field2 = table2.field2,... WHERE table1.id = table2.id; The answer from MySQL is: Unknown table 'table2' in WHERE clause . Heading to MySQL.com the docs tell me nothing than there is a INSERT ... SELECT. In my case this would be an UPDATE ... SELECT coz I don't want a new table, just updating records of an existing with data from another. I'm sure I just miss the right topic to look at. Point me please. Second try: I used UPDATE table1, table2 SET table1.field1 = table2.field1, table1.field2 = table2.field2,... WHERE table1.id = table2.id; It still gives me an error, now in the SQL Syntax when I set the table1.field2 value. It doesn't find the second tables name [You have an error... near ... table(2.field2 should be here)]. Could someone give me the right direction? TIA!
