Re: TIMESTAMP field is updated unintentionally
Marco, mysql update T_ORDH set STATUS=2 where PK_ID=26272; ERSTELL_DATUM is set to the current date. I know that a timestamp takes the current time, if set it to NULL, but since I'm not touching it, it shouldn't change, should it? A quick workaround is mysql update T_ORDH set STATUS=2, ERSTELL_DATUM=ERSTELL_DATUM - where PK_ID=26272; The big question: Is it a bug or a feature? The small answer is: It's a feature, and it's documented as well: Automatic updating of the first TIMESTAMP column occurs under any of the following conditions: The column is not specified explicitly in an INSERT or LOAD DATA INFILE statement. The column is not specified explicitly in an UPDATE statement and some other column changes value. (Note that an UPDATE that sets a column to the value it already has will not cause the TIMESTAMP column to be updated, because if you set a column to its current value, MySQL ignores the update for efficiency.) You explicitly set the TIMESTAMP column to NULL. http://www.mysql.com/doc/en/DATETIME.html BTW: In tables like yours I always have _two_ timestamp columns, like: letzteAenderung TIMESTAMP erstellDatumTIMESTAMP On INSERT, I set erstellDatum to now(). letzteAenderung will automatically be set to the same value. On UPDATE, erstellDatum will be left untouched (because it's not the first TIMESTAMP column), and letzteAenderung will be set to NOW() without me having to think of it.

I was wondering how persons in this community handles changes to the database when your application that uses the database needs some new tables, columns, etc... Do you have an application with a sort of upgrade functionallity that when started checks the database for incosistency and when it finds some updates the database? (ie compares the structure of the table in the database to some template stored in the application or as datafiles/scripts) Or do you use some version system where the application instead of looking for inconsistency just look at the version number of the database, compares it to some internal version, and updates the database accordingly? (ie manually creating all the needed updatescripts that needs to run the application and have the application select between these) Or perhaps you do this update of the database manually when intalling a new version? For me, version 1 would be preferable, but unfourtunally this does not work in every scenario, but i guess that it normally could take care of about 90% off all my changes... the second system would be able to take care of all type of changes, but it requires more labour... so, how do you all manage this? /Christian Andersson - 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?

Batch mode and stored procedures ?
Hi all: I am running MySQL 4.0.9 on Red Hat 7.2 Also using MyODBC to connect to a Win 2K system running a RADIUS server (Steel Belted Radius) I have a MySQL database that tracks usage information coming from the RADIUS server. Everything is working, but the problem is that the RADIUS server can only send a single SQL statement, this is not sufficient for the processing I need to perform. The RADIUS server can call a SQL stored procedure and pass parameters with each call...this is what I need. The MySQL documentation talks about batch files, however I see no mention of how to pass parameters to the batch file. Can a MySQL batch file receieve input parameters? If so, how? Or do I need to wait until stored procedures are implemented in a future version of MySQL? (I understand this is being worked on). Thanks in advance, Bill Brownrigg Project Manager DSL Holdings, Inc.

You compiled apache with ./configure --prefix=/usr/local/apache --enable-module=so so i think your DocumentRoot directive in httpd.conf is DocumentRoot /usr/local/apache/htdocs (i'm not shure, but something like that) and that's why you didn't find a www directory other than /var/www...

Re: Re: Writing a database program in GNU C++ using MySQL.
Hi. Accessing MySQL is equally easy in any of the languages (C++, Perl, PHP, Java). So if that is the main point and it's correct that you, Prabu, are already comfortable with C++, stick with it. A reason a lot of people use Perl, PHP or Java is that many use MySQL in conjunction with web pages and these languages come with built-in support or ready packages for writing CGI for creating web pages. So if you do not write CGIs - and it doesn't sound like this - or you already have appropriate C++ libs for CGI and templates, then the question of which, C++ or Perl is better, boils down to a simple language comparison. In other words, since MySQL is easily accessible in both, put that point out of the requirements list and decide on the remaining factors, whatever they may be for you. HTH, Benjamin.

Both slaves does the replication very fine. Every insert, update or delete is replicated very fine, even with binary data in blob stored. But If I try to stop the slaves with stop slave it takes a very long time until the shell comes back? Any ideas about that? Next Questions: The connection to asia is very slow.

RE: What is faster?..
: The fastest way would be to use C. : But the reason for using a DB would be. : 1. Access to data. You could use PhPMyAdmin or some thing you : put together : to update the policy so making managing the data easy (possibly so non : tickers should make changes). : 2. If the data you are getting needs to be retrieved relationally. : It depends on the complexity of the policy too. If its has several sections, and each section needs to stand out, you will either have to use some markup (doesn't have to be HTML) to tell those sections apart, or store each section as a different raw of a table using a little more complex DB design. This also requires a little more complex SQL query to retrive them. I would probably use some minimum markup to mark the sections, and store the whole policy in a single cell.

Yes. How about simply trying out beforehand?
The O'Reilly Managing Using MySQL show on page 288 a table been created
with two options ...)AUTO_INCREMENT = 1, TYPE=InnoDB;
But the MySQL manual says or:-
table_options:
TYPE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }
orAUTO_INCREMENT = #
.
As it does for create_definition, but that does not mean that you
can only define either a column or a key. The fact that matters is
that one is presented as a list [(create_definition,...)] in the
CREATE TABLE statement, the other is not.
So, yes, the manual is incomplete (especially, because it gives no
indication that you have to seperate the options by comma).
HTH,
Benjamin.

The comma should be omitted. You can specify multiple table options, but
you simply list them one after the other, separated by whitespace.
...) AUTO_INCREMENT = 1 TYPE = InnoDB;
(Note that this particular combination of options is a little strange.
You cannot set the initial AUTO_INCREMENT value explicitly for an InnoDB

the AUTO_INCREMENT option in the example.)

PROBLEM with your JDBC driver - mysql connector.
PROBLEM with your JDBC driver - mysql connector.
I am developing using jdk1.4.1 on Mac OS X. I am using the mysql
driver - mysql connector java 2.0.14. I am creating a table in
mysql
thru java ... the code to do this is below:
try
{
Statement stmt = con.createStatement();
stmt.executeUpdate( CREATE TABLE PARTICIPANT (
+
LOGINID INTEGER NOT NULL,
+
USERNAME VARCHAR (20) NOT NULL, +
PASSWORD VARCHAR (20) NOT NULL,
+
FIRSTNAME VARCHAR (20) NOT NULL,
+
LASTNAME VARCHAR (20) NOT NULL,
+
EMAILADD VARCHAR (20) NOT NULL,
+
ORGANIZATION VARCHAR (20) NOT NULL, +
ENABLED BIT NOT NULL,
+
GRADELEVELS VARCHAR (80), +
PRIMARY KEY( LOGINID )
+
));
stmt.close();
}
catch(SQLException ex)
{
ex.printStackTrace();
}
The table gets created properly. I check this from the mysql
prompt.
Now i insert 2 records in the table above thru my java code . The
code
that does that is below:
try
{
Statement stmt = con.createStatement();
PreparedStatement pstmt = con.prepareStatement(INSERT
INTO PARTICIPANT VALUES
+
(?,?,?,?,?,?,?,?,?));
pstmt.setInt(1, p.getLoginId());
pstmt.setString(2, p.getUserName());
pstmt.setString(3, p.getPassword());
pstmt.setString(4, p.getFirstName());
pstmt.setString(5, p.getLastName());
pstmt.setString(6, p.getEmailAdd());
pstmt.setString(7, p.getOrganizationName());
pstmt.setBoolean(8, p.isEnabled());
pstmt.setString(9, (new
DataTypeConverter()).getString(p.getGradeLevels()));
pstmt.executeUpdate();
pstmt.close();
}
catch(SQLException ex)
{
ex.printStackTrace();
}
For both the above sniplets of code i am using a connection object
from a pool of connections that i create to the database at start
of
application startup. These connections are closed when the
application
exits.
PROBLEM:
The records get inserted in a blank table when i use my java code
to
do so. When i delete a record from the table from the mysql prompt
and
then go back to my java code to insert the same record it gives me
the following error:
java.sql.SQLException: Invalid argument value: Duplicate entry '1'
for
key 1
at com.mysql.jdbc.MysqlIO.sendCommand(Unknown Source)
at com.mysql.jdbc.MysqlIO.sqlQueryDirect(Unknown Source)

com.wavesinmotion.cw.classes.db.DBWriter.setParticipant(DBWriter.java:8
5
)
at
com.wavesinmotion.cw.classes.db.DBWriter.main(DBWriter.java:36)
This i dont understand since the record with that primary key i
have
already deleted from the mysql prompt.
When i try to enter a record with the same key using the mysql
prompt
the record successfully gets inserted into the table;
I suspect a bug in your jdbc driver .. .whats the solution or fix
to
this ?

Mufaddal.

RE: timing
Have you checked for network problems? You might try FTPing a file to and from the production server, or something similar, just to rule this out. I've had slowness problems with various apps that were driving me *nuts* until I found a network issue causing them. In a few cases I had a duplex mismatch -- an ethernet card set to full duplex connected to a half-duplex hub/switch, or vice versa. This results in a connection that appears fine when you ping and works great under light traffic, but bogs down with massive numbers of collisions as soon as you do anything that involves moving lots of data. The collisions may not show up in the statistics since the end that's set to full duplex won't notice them. Letting the card auto-detect the duplex setting does *not* always work right...

Re: creating update files
Hi. On Fri 2003-01-31 at 12:32:51 +0100, [EMAIL PROTECTED] wrote: Hi there, I have a little question for you in the mysql community.. I was wondering how persons in this community handles changes to the database when your application that uses the database needs some new tables, columns, etc... I think this always depends on your use case, but since you wanted to know how we handle this... Do you have an application with a sort of upgrade functionallity that when started checks the database for incosistency and when it finds some updates the database? (ie compares the structure of the table in the database to some template stored in the application or as datafiles/scripts) Or do you use some version system where the application instead of looking for inconsistency just look at the version number of the database, compares it to some internal version, and updates the database accordingly? (ie manually creating all the needed updatescripts that needs to run the application and have the application select between these) Or perhaps you do this update of the database manually when intalling a new version? Effectively that is what I do. Using the development database, I write the application and change the database accordingly (and save the statements I use for this). When the program is ready, I write a script with the SQL commands needed to update the database to the new version (most times that involves only slightly correcting the statements I saved beforehand) and test that it results indeed in the wanted table structure. Then I take both, the new program and the SQL script and install them in parallel on the production machine. For me, version 1 would be preferable, but unfourtunally this does not work in every scenario, but i guess that it normally could take care of about 90% off all my changes... the second system would be able to take care of all type of changes, but it requires more labour... Huh? I am not sure why you think #2 is more work. I think an application which tries to make consistency checks and do the correct SQL statements (#1) is much more complex than one that simply executes some script based on a version number (#2). Especially since you probably already have those SQL scripts as side product of your testing (if you are using a GUI, I sincerly hope it is able to log the commands it executes for you. Or use the update log of MySQL). IMHO, the real (potential) drawback of #2 is that it relies on the version number being correct and therefore fragile against change. E.g. my experience shows that emergencies sometimes require to make changes by hand, which invalidates the version, and it being an emergency, the change is high that the version is not changed accordingly. So I think that #1 has the advantage of being adaptive while being a lot of work. I am also not sure, why you think that #1 would be only able to handle 90% of the cases, theoretically it can dump the whole database structure to find out about types and whatever. Hm. Maybe that's why you don't think it is much work - only concentrating on the common cases? so, how do you all manage this? I don't use the first two solutions, because I am around when I do updates anyhow (and I wouldn't want the application to change the production system significantly when I am not around), so I prefer doing the version check myself. Maybe that is, because I only have a handful of machines to take care of. If I had to roll out changes to several hundreds of machines (possibly clients) and couldn't be sure which version is running, I would use a of variation of #2: write a little script additionally to the SQL update-script, which makes a SQL dump of the existing database structure, compares (maybe via MD5 sum to safe space) that with one that I made on the test system and bails out, if they differ. That can be made to work with several versions. In other words, it would not check a version number saved in the database, but determine the version by the database structure itself. That would give #2 with the assurance that an update script is only run, if the database structure is as expected, no matter happened to the database in-between (it is fascinating what clients can do to files they are not supposed to even know about ;-).

Re: partitionong MyISAM tables??
Prasanth, Is there any way to partition MyISAM tables in mysql? i have a huge table and want to partition it. An easy way to slice it into chunk would be: CREATE TABLE tblPart_1 SELECT * FROM tblFull LIMIT 0,1000; CREATE TABLE tblPart_2 SELECT * FROM tblFull LIMIT 1000,1000; CREATE TABLE tblPart_3 SELECT * FROM tblFull LIMIT 2000,1000; etc. With InnoDB tables, you can do exactly the same. If you need the tables to look like one big table later on you can use the MERGE table format (if your tblPart_* are MyISAM tables). CREATE TABLE tblFullMerge (col1 ..., col2 ..., ...) TYPE=MERGE UNION(tblPart_1,tblPart2,...); With InnoDB, you cannot use MERGE tables. I don't know if that's what you want.

Heh. Why not just try it? :)
The O'Reilly Managing Using MySQL show on page 288 a table been created

No comma is needed.
But the MySQL manual says or:-
table_options:

Hrm. It does not look like we explicitly state that you can use
multiple options anywhere on the CREATE TABLE page in the manual.
I will ask our documentation team to fix it.

Problems with INNODB table
Hello!! I have various databases, one with a table with more than 3 millions of registers, and other has 250 MB, 50MB. My ibdata1 grow to more than 1 G, well I do not want my big database, I drop the database but the size of the ibdata continues with the same size, what can I do?? I waant my ibdata with only the small databases, but I want with the correct size not 1 G!, How can restore to minium size the ibdata file? without making mysqldump of all the databases and creating a new one, if it is posible??

Most of this depends on which MySQL version you use and which table type, unfortunately. OTOH, for the common case all just work fine and relying too much on the edge cases is not a good idea anyhow. Some relevant manual pages are: 1: http://www.mysql.com/doc/en/example-AUTO_INCREMENT.html 2: http://www.mysql.com/doc/en/SEC471.html 3: http://www.mysql.com/doc/en/CREATE_TABLE.html 4: http://www.mysql.com/doc/en/ALTER_TABLE.html Ex. suppose I have an autoincrement field called num and the last one has value of 10. I delete the last on and insert a new one. Which value will it have ? 10 or 11 With the ISAM and BDB table handler, you will get 10 [see 3]. With MyISAM 11 [3]. With InnoDB 11, except if you restart MySQL in-between, then you will get 10 [2,3]. The common part is: You will get a new number, which is at least greater than the current maximum value, but numbers may be reused. If you ignore older table handlers (ISAM,BDB) and ignore server restarts (my last was about 100 days before): You will get a new, never-used-before number that is greater than the current maximum value with MyISAM or InnoDB. I read that if I issue a query delete * from table and delete from table I have diferent results (in regards to the auto increment field). Is this correct ? The difference is whether you specify a WHERE clause (delete * is not correct syntax, AFAIK), i.e. with DELETE FROM table_name (without a WHERE) the sequence starts over (for any table handler) if you are in auto-commit mode.

mysqldump --allow-keywords has no effect. Alias for -Q?
Description: The --allow-keywords option has no effect if the server can use the SHOW CREATE INFO command (it's the other else branch). All the new code only make use of opt_quoted which is set by the -Q option and quotes illegal table/column names instead of prepending them with the database name like --allow-keywods would do. How-To-Repeat: CREATE TABLE `by` (`char` char(30)); and then try to dump it using --allow-keywords and -Q. Fix: If it is backwards compatible to e.g. version 3.21 which didn't know the SHOW CREATE TABLE command, then make --allow-keywods just an alias for opt_quoted (-Q).

Can anyone help me, or direct me to a good source of information related to running mysql on OS X? For example, I can't figure out where in my system the mysql database files are located. If I could, at least I could just make backup copies to CD. Any help would be greatly appreciated.

RE: setting auto increment start value
This actually is more tricky than it sounds. Firstly the table already exists. So create table is an option only if you were going to recreate a new table with an auto_increment column, then move the rest of the data (except for the index column) in to the new table, drop the old table and re-name the new table. a shorter approach maybe to drop the column and add a new auto_increment column with auto_increment of 1000 or whatever you like. and secondly SET INSERT_ID works for values greater than LAST_INSERT_ID as expect but for values less than LAST_INSERT_ID (e.g. gaps created by delete command) only works for the next generated value. for instance if LAST_INSERT_ID is 7 and you delete the last 5 records... then SET INSERT_ID = 3; INSERT INTO table values (null, ..), (null, ..); will result in: 1 4 // first inserted record 8 // second inserted record -- id is 8 not 5! but SET INSERT_ID = 60; INSERT INTO table values (null, ..), (null, ..); will result in 1 61 // first inserted record after set 62 // second inserted record -- follows the first The logic of AUTO_INCREMET is consistent but its realization is somewhat unexpected at the beginning. --- Sherzod Ruzmetov [EMAIL PROTECTED] wrote: : Am Donnerstag, 30.

Making Lin/Win share DataSource

But anyway, me too,I've solved the problem as well...:) :) So, here is what I did in term of commands: 1- $ mount /home/myfiles [this /home/myfiles is the D:\ partition in my dual-boot laptop. I'm now mounting it simply still as a normal user -- NOT as root] 2- $ mkdir /home/myfiles/MySQL 3- $ su [obvious..., accessing the root privilege] 4- $ mv /var/lib/mysql/* /home/myfiles/MySQL/ 5- $ vi /etc/my.cnf [surely..., changing the datadir line to become and to look like: datadir:/home/myfiles/MySQL/ 6- $ safe_mysqld And all done! The only mistake that I did earlier was that I as a normal-user copied/moved the data to the vfat partition. This way, when I started mysqld as root, I had no privilege at all over the datasource. But..., wait..., I am now still in Linux and haven't gone to or tried it in Windows [kind of allergic..., you know :)]. But, assuming the core datasource for Lin-Win is not different at all, I believe that in Windows it wouldn't be a big deal at all. Nice! So now no matter I'm in Windows or Linux, my data can always be intact...:) BTW..., if one tries this way too, please inform the success/failure. JD JD, my answer may seem ridiculous, too, but with the following setup you should be able to use MySQL databases and tables both under Linux and Windows on the same machine. About the only thing you need is access to the MySQL data directory from both Linux and Windows. Regardless of the operating system, mysqladmin variables will show you where DATADIR is. Of course (though it may sound even more ridiculous), you have to have MySQL installed both under Linux and under Windows. Whether you've started mysqld or not, you can issue mysqld --print-defaults to find out the location of DATADIR. However, this will not show you DATADIR if it's not in my.cnf / my.ini. Now, let's say DATADIR is in /var/lib/mysql/ under Linux, and under Windows this is c:\mysql\data\ (I'm not informed how paths will look like when you share them between OS's). In this case, you would edit /etc/my.cnf under Linux and fill in: [mysqld] datadir=/var/lib/mysql And, under Windows, this would be the following in c:\winnt\my.ini (assuming you boot Win NT/2000/XP): [mysqld] datadir=c:\mysql\data Now, I suggest you start the MySQL server (both OS's) as follows: shell mysqld --standalone --console This will output a lot of start information, so you can find out what's going wrong at startup.

On the other side , if MySQL considers covered queries ,then 14 full text indexes are gona be better .

Re: line breaks
Tarik, - what is the stored character code of the enter key in the text field, i am figuring out to find that character and replace it with the br element, for the exact display, The character is \n (the new line character). If you use PHP and have magic_quotes=on in your php.ini, PHP will automatically escape certain characters like \n. If magic_quotes=off, you can use the addslashes() function to accomplish this. When retrieving the data out of MySQL to display them in a textarea field once again, you have to do nothing. The web browser will take care of converting \n into something the operating thinks is a new line (Unix: \n, Windows: \r\n, MacOS: \r). If you want to display the data outside of form fields, you will have to convert \n into something HTML knows is a new line. HTML uses for example br or p for this. In PHP, you can use the nl2br() function that will convert \n into br. If you don't use PHP, things might be a bit more complicated.
