Re: Formatting Large amounts of Text into Mysql

If you really want it to look just like the user saw it (although there are of course no guarantees that in will look _good_), look at the non-standard WRAP attribute to the TEXTAREA tag.

What you can do is either use the mysql command line client and to a file, or just loop over the result and save it in whatever format you wish in your favourite language. Is there a global or local configuration that can be specified where mysql will write to? It will write where you tell it to, if that location fulfils the criteria listed in the manual. I think mysql chdir()s to the data directory, but I wouldn't rely on it.

Re:MySQL-Front can't open some InnoDb tables ***
Ansgar, what could cause the problem Brent reports in MySQL-Front? InnoDB returns the error Can't open file mytable.InnoDB when it cannot find the table in its internal data dictionary. Maybe the case of letters in the database name is wrong? Brent, if you look at the MySQL server error log, something like 'hostname'.err, what does InnoDB say in it? You could try the MySQL-4.0.0 with your database. Then you could do mysql create table innodb_table_monitor (a int) type = innodb; which makes the MySQL server mysqld (not the client mysql) to print the contents of InnoDB internal data dictionary to the standard output. To see it it is best that you start mysqld-max.exe from the MS-DOS prompt, not as a service, or not inside a safe_mysqld wrapper. Actually, when debugging, it is always best to start mysqld from the MS-DOS prompt because then you see what is happening. Regards, Heikki http://www.innodb.com/ibman.html I'm trying out MySQL-Front on a Win2k machine and it is having a problem opening some of my InnoDb tables. I can open any of my InnoDb tables if I explicitly specify the database name in the Connection window. But if I leave the database name blank I'll see the database tree in the pane on the left. If I try and select one of my InnoDb tables from underneath the database node, I'll get an error window saying MySQL Error - 1016 Can't open file mytable.InnoDB'. (errno: 1). Clicking on the database name says one or more of the InnoDb tables are 0KB. I know there is data in the tables because I can access them in MySQL. This is the same table that I was able to open in MySQL-Front when I specified the database explicitly in the Connection window. So why does MySQL-Front sometimes have a problem opening InnoDb tables?

Uneven replication nodes??
I am looking for a creative way to optimize my web application (largely reads) with a transaction firehose on the data input side. Batch vs. OLTP, if you will. Is there any technical reason why I could not configure the master database without indices and the slave(s) _with_ indices? The intent being to isolate the inbound transactions from the reads _and_ make the database inserts as simple as possible (e.g. few or no indices). Several slaves could be configured to throttle performance on the web side (more reads, move slaves, etc.), which could gain a performance edge by indexing. For disaster recovery of the master, one slave could be untouched and not indexed. I'd be interested to hear comments.

When it searches, it doesn't know the result of count so you cannot specify it in the where clause. This would work, but you have all the records retrieved, not only the ones who have more than 10 in the group: select hpnumber,count(*) as counts from Mobile_Ringtone_Manialogs where datesent between '2001-09-24' and '2001-10-24' and (returncode 0 and returncode 10) group by hpnumber order by counts DESC To do what you want, you would need to do a subquery. That's where PostgresSQL has an advantage over it. Right now, you need to do two steps: Get all the records with the counts associated to them. When processing the data, ignores those having a count under 10. - 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?

Slow multi-column index
Hello all Grateful for any help on this - I have a table (definition for MAIN below) with a number of indexes corresponding to various frequently used queries. A SELECT statement using one of the multi-column indexes is running very slow if it retrieves data that is not in in the index itself. For example, a SELECT count(*) FROM MAIN WHERE... takes 0.04 seconds, but SELECT fileName from MAIN WHERE... takes 20 seconds. The table currently has around 18000 rows, and the DB is around 400MB. I'm wondering whether this has something to do with the following words of wisdom in the reference manual: For tables that changes a lot you should try to avoid all VARCHAR or BLOB columns. You will get dynamic row length as soon as you are using a single VARCHAR or BLOB columns. but I don't see why this should matter. Why does it matter that row lengths are dynamic ? Surely the index doesn't just specify a row index that is multiplied by the row length ? Surely it contains some sort of row data offset to allow for variable row lengths. If any use, here's the table definition: CREATE TABLE MAIN ( idINT(4) AUTO_INCREMENT PRIMARY KEY, addedDateTime DATETIME NOT NULL, filePath VARCHAR(100) NOT NULL, fileDateTime DATETIME NOT NULL, fileDate DATE NOT NULL, fileName VARCHAR(255) NOT NULL, mediaType VARCHAR(100) NOT NULL, key1 CHAR(32), key2 CHAR(32), language CHAR(4), headline BLOB, enStory TEXT, searchSlug TEXT, searchCodes TEXT, fileData LONGBLOB, INDEX (filePath, mediaType), INDEX (addedDateTime, fileDateTime, fileDate, mediaType, filePath), INDEX (fileDate, filePath, mediaType), INDEX (fileDate), INDEX (fileName), INDEX (mediaType), INDEX (key1), INDEX (key2), FULLTEXT (enStory), FULLTEXT (searchSlug), FULLTEXT (searchCodes) ) TYPE=MYISAM; and the slow query is something like: SELECT fileName FROM MAIN WHERE (fileDate='20011021') AND (filePath='OLWWPICGLSP) AND (mediaType='TEXT'); (~20 seconds) EXPLAIN says this will use the 3rd index (fileDate, filePath, mediaType) which looks fine. If the query is changed to: SELECT fileDate FROM MAIN WHERE (fileDate='20011021') AND (filePath='OLWWPICGLSP) AND (mediaType='TEXT'); (0.02 seconds) This is fine because it can get 'fileDate' from the index itself. So, is it *really* the variable length row lookup that's taking all the time here ?

Yes this is what we're doing. Just put the pathname to the file into a VarChar field.

looping
Hi there, I have a small question for you all (and yes I have searched the documents but not be able to found what I want) Lets say that I have a table with these values 1, 5 and 7 is it possible to create an sql query that will loop through these values a certain amount of time for example if i wanted 8 rows I would get 1, 5, 7, 1, 5, 7, 1, 5 as output.. I'm currently doing this looping in my application but it would speed things up if mysql could do this for me.. since I could then do some joins and retrieve values from other tables faster. /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?

Re: looping
You can't at this point. But anyway, it is usually better to make your application do the work than your database. MySQL doesn't process functions faster than you would with arrays (which is what it would have to do ) and it's better to take as much load off from your database. Even if you could do it, it wouldn't be faster and it would take a toll on your DB, making other simultaneous queries slower, and your whole project would be slower. Whenever possible, have your application process functions for your database. A database should concentrate on queryiong the data and your program should perform as many functions as possible.

Re: Slow multi-column index
So, is it *really* the variable length row lookup that's taking all the time here ? I don't see how. 18000 record is nothing and varchar searches are pretty fast. On top of that, you first search is on the date which would be extremelly fast and narrow the next searches to many less records. Are you sure it is the database that is slow to retrieve your result or could it be with other code you have around the database but within you time markers? Hi - yes, it really is the SELECT statement that's taking the time. The timings I gave are directly from the mysql command line, ie. reported by mysql.exe itself, not my code. By the way, only around 60 rows are returned by the query. I'm sure you're right, that VARCHAR searches are fast, since the 2nd query (SELECT fileDate...) is near instantaneous and is searching on the same VARCHAR columns as the slow one. The difference between the slow fast queries seems to be the fact that the slow one is having to retrieve the row data from the table rather than the index itself. When an index 'returns' a query match, does it also contain some sort of lookup into the table to allow the row itself to be retrieved ? Or, if rows are variable length, does MySQL have to do a linear scan through the database to find the row ? That's what I'm wondering because of the reference manual warning about variable length rows.

Re: Slow multi-column index
Hi Phil, I suspect you have already answered your own question! Warning: high ignorance factor - am currently researching indexes for myself - if I can't figure it out for myself, you can help me with that later... When the SELECT can, it will answer a query from a scan-of/data-retrieval-from the index file(s) alone. Under such conditions it will respond v.quickly - this applies to two of your examples: SELECT count(*) FROM MAIN WHERE... SELECT fileDate... the latter being fulfilled from your INDEX (fileDate), - which incidentally looks superfluous because wouldn't any query on the fileDate index be equally well covered under the previously defined INDEX (fileDate, filePath, mediaType), You point to the above being fine and dandy, but performance problems resulting whenever the actual data table is required/accessed to provide the data. In this there is only evidence from one data-selecting query (ie a SELECT that cannot be entirely satisfied by data held in the indexes). Do you experience equivalently long response times from other such queries? Another part that you may have self-answered was to do with variable length fields/rows and rate of inserts. Is it worth trying a reorg (ie to produce a 'state' of zero inserts) and then comparing 'before' and 'after' response times? [really high ig-factor here! such an action is usually designed to improve the b-trees in the indexes, and I'm not at all sure of its effect on the layout of a data table with heavy use of variable length fields] Because of exactly this 'fear' (if not 'issue') a device I have used in the past (but not in MySQL) was to move the variable length stuff to a separate table, and keep the rest/not too much variable-len in the 'main table'. Ok the absolute one-to-one relationship means that this involves de-normalising the database, but such would be 'legitimised' if it helps cope with a performance bind (don't tell the RDB-police though!) Make any sense? =dn So, is it *really* the variable length row lookup that's taking all the time here ? I don't see how. 18000 record is nothing and varchar searches are pretty fast. On top of that, you first search is on the date which would be extremelly fast and narrow the next searches to many less records.

There is a lot of validation and assertion code when you compile InnoDB with the debug options switched on in /innobase/include/univ.i. Then InnoDB spends 99 % of CPU time running the validations. These validations will also catch some of new bugs. For example, if UNIV_SYNC_DEBUG is defined, then InnoDB checks the latching order of semaphores during execution.

RE: Pictures in mysql
as someone suggested, if you have ASP, you can get an upload module. if you
have php 4, you already have full capability to upload images, either using
FTP, or if your server will let you copy from the temporary directories, for
instance:
page 1 has a form that allows you to select an image on your harddrive, in a
variable called fileupload.
the form target has a script similar to this:
if(!$fileupload = none) {
copy($fileupload,[target]);
unlink($fileupload);
}
at the same time, you can simply insert [target] reference into your mySQL
database. the above will only work, of course, if you have the correct
permissions on the server's temp folder.

SCO OpenServer 5.0.x and Mysql DBI Driver

Table Crashes Constantly on prod server!!
I am running 3.23.40 on a dual pentium III 800 with 1 GB Ram. I have been getting an table handler returns error 127 error If I fix the table with myisamchk -r or -o it will work for a while and then I will get the same error again.

However mysqld is consistently using about 30% of the Memory and total utilization of memory on the server is holding about 85% of standard memory but 0.2% of swap used. Could this have anything to do with the settings for the server?

Re: DATA DIRECTORY bug on Win32
At 14:24 24/10/2001 +0400, Mike Blazer wrote:
Hi Mike,
Thanks for the bug report.
The explanation why the insert command doesn't works on Win32,
is because the link file pointing for the DATA DIRECTORY wasn't
created in the create table command, like the Unix version does.
The Win32 OSs don't have a native symbolic link feature and the
today symbolic link support on Win32 is made creating a plain text
file with the extension *.sym on \data directory and contains the
path of the whole database.
Then DATA DIRECTORY feature should be handled in a different way
on Win32 than is made on Unix.

Hello guys!
I'm sorry to report a small problem with the newest MySQL-4.0.0 that
looks like a bug for me.
This is a very-very nice and awaited feature DATA/INDEX DIRECTORY in the
CREATE TABLE statement. On my Win95 it creates .MYD file but
immediatelly fails in the 1st INSERT statement reporting
g:\mysql-4.0.0\binmysqlc ranks G:\_patrick\test1.sql
ERROR 1105 at line 32: File '.\ranks\test1.MYD' not found (Errcode: 2)
Line 32 is the first INSERT.
I tried to import an SQL file with
CREATE TABLE test1 (
...
)TYPE=MyISAM MAX_ROWS=4294967295 PACK_KEYS=1
DATA DIRECTORY=G:\\mysql-4.0.0\\data\\r2;
INSERT INTO test1 VALUES ('referer - pages per
visitor',998092800,1,1,28,38,6,26);
etc.
The file was created by mysqldump - so, no errors, I just added
DATA DIRECTORY=G:\\mysql-4.0.0\\data\\r2;
Yes, I tried it both in Win32 and forward-slash form like
DATA DIRECTORY=G:/temp;
same error.
And it kinda could not understand any relative path at all
DATA DIRECTORY=./r2;
gives
ERROR 1103 at line 11: Incorrect table name './r2'
DATA DIRECTORY=r2;
gives
ERROR 1103 at line 11: Incorrect table name 'r2'
In the last two cases even .MYD file has never been created.
That's it.
Thanks... and many thanks - to all of you at Mysql AB

RE: select stmt problem
Well, count(*) is not a column, it is a function of a column. When it searches, it doesn't know the result of count so you cannot specify it in the where clause. This would work, but you have all the records retrieved, not only the ones who have more than 10 in the group: select hpnumber,count(*) as counts from Mobile_Ringtone_Manialogs where datesent between '2001-09-24' and '2001-10-24' and (returncode 0 and returncode 10) group by hpnumber order by counts DESC To do what you want, you would need to do a subquery. That's where PostgresSQL has an advantage over it. Right now, you need to do two steps: Get all the records with the counts associated to them. When processing the data, ignores those having a count under 10. Usually, when somebody suggests that you need a subquery in a SELECT statement, they're just plain wrong. In my experience, I've never run across a real-world nested SELECT that couldn't be expressed a different (and more efficient) way. For deletes and updates, the nested SELECT's are much more useful. In this case, you need to put your clause counts 10 in a HAVING clause. Try this: select hpnumber,count(*) as counts from Mobile_Ringtone_Manialogs where datesent between '2001-09-24' and '2001-10-24' and (returncode 0 and returncode 10) group by hpnumber HAVING counts 10 order by counts DESC Steve Meyers - 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?

Creating InnoDB tables

I save the .ini file. Then I try to install mysqld-max-nt service by Typing c:\program files\mysql\bin\mysqld-max-nt --install It fails to install the service. In addition if I shut down my server, and fire it up again it won't start. As soon As I get rid of the new parameters except the innodb data file path, it starts working again. Does anyone knows what is going on. I'm using mysql 3.23.39 on Win2000. All I want is to be able to make it so that I can work with InnoDB as oppose to MYISAM as default.

RE: Slow multi-column index
I'm wondering whether this has something to do with the following words of wisdom in the reference manual: For tables that changes a lot you should try to avoid all VARCHAR or BLOB columns. You will get dynamic row length as soon as you are using a single VARCHAR or BLOB columns. but I don't see why this should matter. Why does it matter that row lengths are dynamic ? Surely the index doesn't just specify a row index that is multiplied by the row length ? Surely it contains some sort of row data offset to allow for variable row lengths. I've seen it happen -- we had a table that was taking 2-3 seconds for a keyed lookup, and it should have been in the miniscule range. We OPTIMIZEd the table, and after that the queries in question executed in 0.1 or 0.2 sec. However, this was after several months of abuse -- it shouldn't be the case on a newly created table.

RE: Sessions
A quick check of a MyODBC connection made from Access 2000 to a MySQL database (with 5 tables open) shows as a single process in WinMySQLAdmin... the total connections show up as 3 (including the WinMySQLAdmin connection, I assume). Bumping that up to ten open tables and one open query increases the connections to 5... opening 4 more queries leaves the number of connections at 5... Not very scientific, but I hope it helps.

quotes
This is more of a php problem than mysql, but since I am using them in combo... I have a database for people from the former Soviet Union that have participated in a certain program. One of the fields represents the name of their company. It is common (although not universal) practice to use quotes when writing the name of your company, (i.e. Limited Liability Company Widgetron). Anyhow, one of the scripts that I am using has ? echo $companyname;? It works great when the person isn't using quotes in the company name, but when they are the quoted part disappears. If everyone was using quotes, I think I could deal with the problem (however, that the quotes don't include the whole field is somewhat troubling). If no one was using quotes, there would be no problem. How do I write a script that detects the presence of quotes and based on their presence or absence decides how to format them.

If your key doesn't fit in the key buffer, my tests have shown that there is a HUGE performance loss. That's a very good point - thanks for bringing it up.

Hi, i ran into a pretty boxy problem this morning, as I tried to login as mysql manager with #mysql -u root -p # (i forgot the password) its either this, or the other administrator, whom i cannot contact right now, changed the password without my knowledge of it. What can i do? is there some kind of recovery procedure? Or can i reinstall without affecting already present databases? thanks to all, oscar -- PGP Key fingerprint = 87 83 5F D3 8D D4 B9 DC 4F 15 B1 68 4E FE 2D AE - 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?

Problem with NULLs where they shouldn't be in mysql.user
Under MySQL 3.23.40/Win32 and 3.23.33/Linux, neither mysql.user.user nor mysql.user.password are permitted to have NULL values: mysql insert into mysql.user set user=NULL,password=NULL; ERROR 1048: Column 'User' cannot be null However, the default 'guest' user has NULLs for both of these values. In addition, GRANT can create NULL values for passwords (and possibly users). This causes an interesting problem using certain select queries, notably this one and similiar variants: SELECT user FROM mysql.user WHERE user IS NOT NULL will return all of the users, even the NULL values. I believe this is caused by the optimizer happily taking the user IS NOT NULL part out of the query, because it sees that the user column doesn't support NULL, and thus obviously everything will be NOT NULL. - Daniel Grace - [EMAIL PROTECTED] http://dewin.oldbattery.com/ and http://dewin.venura.net/ - 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?

Query help...
I'm trying to come up with a query to do the following... I'm not having lots of luck :( The table is a user database. The columns I'm interested in are: username, lastip. I'm interested in pulling information out that would show usernames for each IP that appears more than once in the database.. i.e. usernameip persona1.1.1.1 personb1.2.3.4 personc1.1.1.1 I'd be interested in seeing persona and personc (both have 1.1.1.1 ip's) I've tried.. SELECT lastip,count(*) FROM users GROUP BY lastip; but that only gives me an unordered list of the # of times an IP is used.. SELECT distinct(count(*)) FROM users GROUP BY lastip; but that doesn't join the info -- nor give me the ip's -- just frequency (when I add 'lastip' to the select I get an error) I'm thinking that I'm going about this the wrong way..

Absolutely Cannot Do Anything
Hi I've installed MySQL 3.23.43 binaries on Solaris 2.5.8 without UNIX root privilege. During installation, someone else with UNIX root privileges ran mysql_install_db, added a normal user xxx and an admin yyy. At this point I do not see yyy owns all directories and all files. Following bullets describe what I have got right now. Scenario I .Start mysql using ./safe_mysqld -user=xxx .Cannot connect to mysql through ./mysql -u root with or without password. .Can connect to mysql using ./mysql -u xxx .Cannot select anything from mysql database as user xxx .Cannot create database, tables, as xxx or yyy . Absolutely nothing .Can kill mysql as yyy or xxx. Scenario II .Start mysql using ./safe_mysqld -user=yyy .Cannot connect to mysql through ./mysql -u root with or without password. .Can connect to mysql using ./mysql -u xxx .Cannot select anything from mysql database as user yyy. .Cannot create database, tables, as xxx or yyy . Absolutely nothing .Can kill mysql as yyy or xxx. When I ran ./yyy variables, it showed datadir is /usr/local/mysql/var/. After I start mysql using ./safe_mysqld -u=xxx or yyy, shell command ps -ef shows/usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local. What is my true datadir?I tried to do chown -R ... in either /usr/local/mysql/var/ or /usr/local/ . It only showed that I was not a owner of anything. Here is what I need. How do I get there? Should I reinstall MySQL with UNIX root privilege? 1.Normal user xxx to be able to be able to use MySQL DML and grant/revoke privileges per his ownership. 2.Admin user yyy to own all directories and all files, including system files and execute all MySQL DDL. 3.I can start mysql as myself and chown all directories and files.

Re: relational DBMS vs object-relational DBMS
http://searchdatabase.techtarget.com/sDefinition/0,,sid13_gci213671,00.html An object-oriented database management system (OODBMS), sometimes shortened to ODBMS for object database management system), is a database management system (DBMS) that supports the modelling and creation of data as objects. This includes some kind of support for classes of objects and the inheritance of class properties and methods by subclasses and their objects. There is currently no widely agreed-upon standard for what constitutes an OODBMS, and OODBMS products are considered to be still in their infancy. In the meantime, the object-relational database management system (ORDBMS), the idea that object-oriented database concepts can be superimposed on relational databases, is more commonly encountered in available products. An object-oriented database interface standard is being developed by an industry group, the Object Data Management Group (ODMG). The Object Management Group (OMG) has already standardized an object-oriented data brokering interface between systems in a network.

Re:MySQL-Front can't open some InnoDb tables ***
Hi! Ok, it was probably how Brent had moved .frm files around. MySQL-Front is not to blame. Regards, Heikki http://www.innodb.com At 02:25 PM 10/24/01 -0500, you wrote: At 03:25 AM 10/24/2001 , you wrote: Ansgar, what could cause the problem Brent reports in MySQL-Front? InnoDB returns the error Can't open file mytable.InnoDB when it cannot find the table in its internal data dictionary. Maybe the case of letters in the database name is wrong? Brent, if you look at the MySQL server error log, something like 'hostname'.err, what does InnoDB say in it? You could try the MySQL-4.0.0 with your database. Then you could do mysql create table innodb_table_monitor (a int) type = innodb; I'm running Win2k and (as far as I know) these MySQL v4 binaries aren't out yet. which makes the MySQL server mysqld (not the client mysql) to print the contents of InnoDB internal data dictionary to the standard output. To see it it is best that you start mysqld-max.exe from the MS-DOS prompt, not as a service, or not inside a safe_mysqld wrapper. Actually, when debugging, it is always best to start mysqld from the MS-DOS prompt because then you see what is happening. I'll make a note of that the next time something goes awry. But I did find out the problem to my Can't open file mytable.InnoDB problem. It was operator error.g The .frm files were to blame. I think I may have created the tables with a redirected MySQL data directory. Even though there was a duplicate set of .frm files in the original directory, they may not have been in sync with the InnoDb internal settings for the table. So I dropped the tables and rebuilt the databases involved and it seems to work fine now. Your suggestion in the MySQL.Err file: Cannot find table iSample/event from the internal data dictionary of InnoDB though the .frm file for the table exists. Maybe you have deleted and created again an InnoDB database but forgotten to delete the corresponding .frm files of old InnoDB tables? was a nice touch. That pointed me in the right direction. I guess I should have looked at that first. Oh well, there's always next time.g Thanks for your help.

Re: relational DBMS vs object-relational DBMS
In Relational Database you usually create tables where the columns are primitive datatypes such as number, varchar2, date (these are oracle primitive dataypes). So... to create a table Customer, for example, you would do something like: create table customer ( customerID number(10), customerNamevarchar2(100), customerStreet varchar2(50), customerCityvarchar2(30), customerState char(2), customerZipCode varchar2(10) ); In an object-Oriented database you can create your own datatypes like: create type ADDRESS_TY as object( Street VARCHAR2(50), City VARCHAR2(30), StateCHAR(2), Zip varchar2(10) ); Then you can create another object that uses this address object like: create type PERSON_TY as object( Name VARCHAR2(100), Address ADDRESS_TY ); Then finally you can create your table like: create table CUSTOMER( CustomerID NUMBER, Person PERSON_TY ); or create table EMPLOYEE( EmployeeID NUMBER, Person PERSON_TY Department NUMBER ); See the difference now? The dataype address can be used separatelly in other tables directly, or it can be agregated to an object like person_Ty and this can be used for many different tables. The power of this is that your company would define certain datatypes instead of expect developer to do it. Work with standards is the first key to do a clean job. Now, imagine different people creating tables as they want. How many different words would exist for the same concept. Street, streetName, address, complement, etc (just for street) zipCode, zip, zCode (etc...) What a mess, and this is actually what we see in the market. I consider this no professional at all. I always like to tell people that work like that the following: JUST MAKE IT WORK DOES NOT NECESSARILL LEADS TO SUCCESS . I have a paper in my web site that is not complete yet, but it gives you some idea on how to map java objects directly to Oracle objects. Remember : ITS NOT COMPLETE YET, SO YOU MAY FIND SOME ERRORS, OR CODES THAT NEED TO BE ADJUSTED TO THE EXAMPLE I POST.

Re: SCO OpenServer 5.0.x and Mysql DBI Driver
Here are my compiling notes. I find gcc the best for compiling both MySQL and Perl modules as outlined below. Compiling Applications for SCO Open Server 5.0.5 Compiling the Tools This CD contains compilers and tools in the sco-downloads directory that can be loaded using the SCO 'custom' utility. The SDK I used was compiled as follows, and resides in the custom directory. To install them, use custom and the media image option.. If you wish to compile them yourself, here are the instructions. You will need the SCO development system. You may check the scripts directory for some zz scripts to help you out. To compile gcc-2.95.2: load SCO cc extract gcc-2.95.2 to a work directory mkdir objdir cd objdir ../gcc-2.95.2/configure --prefix=/usr/gcc make bootstrap make install To compile make: extract make-3.79 to a work direxctory ./configure --prefix=/usr/tools make make install To compile binutils: PATH=/usr/tools/bin:$PATH ; export PATH extract binutils-2.9.1 to a work directory mkdir objdir cd objdir ../binutils-2.9.1/configure --prefix=/usr/tools make make install Compiling MySql To compile MySql you will need gcc-2.95.2 described above, along with FSU-pthreads-3.5c from mysql.com. You will find custom loadable copies in the 'custom' directory. You will also need to load the linker and libraries off your SCO 5.0.5 CD. I use the following script to compile and install MySql. PATH=/usr/gcc/bin:/usr/tools/bin:$PATH CC=gcc CXX=gcc ./configure --prefix=/usr/local/mysql make make install Compiling Perl To compile perl: edit hints/sco.sh and change: ld='ld' to ld='gcc -fpic' I use the following script to compile and install perl. PATH=/usr/tools/bin:/usr/gcc/bin:$PATH LD_RUN_PATH=/usr/local/mysql/lib/mysql export LD_RUN_PATH sh Configure -Dcc=gcc -Dprefix=/usr/local/perl -d make make install Compiling Perl Modules To compile DBI and Msql-Mysql-modules just follow the directions found in the packages.

RE: Query help...
David, The way I accomplish this is using two queries...first I write a general query that shows the IP address of any IP that has more than one user associated with it: SELECT DISTINCT(ip) AS ip, COUNT(*) AS count FROM members GROUP BY ip HAVING COUNT 1 ORDER BY count DESC I tie this into a PHP script that lists all the IPs (as links) to another report. This report selects all the usernames for that IP SELECT username FROM members WHERE ip = '$ip' ORDER BY username This works well for me, you just have to pass the variable from one page to another.

No this is not a known problem. Can you find out what could be the problem ? The symbol 'mysql_module_entry' doesn't come from the MySQL library, so this is a PHP problem. Note that you can use MySQL 4.0 with the old MySQL 3.23 library without any problems.

Re: Cant optimize self-join order
Eric == Eric [EMAIL PROTECTED] writes: Eric What is quite puzzling is MySQL's estimation of the number of rows Eric from each of the self-joins. The conditions on alias queryTable0 Eric actually refer to 1582 rows, and the conditions on alias queryTable1 Eric refer to 39 rows. Notice in the EXPLAIN below that when I flip around Eric the join order, MySQL thinks that 1152 (which is its estimation for Eric 1582) rows are coming from queryTable1, whereas with the original join Eric order, it thought 1152 rows were coming from queryTable0...this seems Eric like a bug to me since the conditions on those two aliases are the Eric same between the two queries. Only the FROM index queryTable0, index Eric queryTable1 is flipped to FROM index queryTable1, index queryTable0. Eric See below, Eric eric. It's actually quite clear why you get the same number of estimated rows in both cases. Because the alias are identically used and MySQL picks the same index for both combinations, it will estimate the same number of rows in both cases. The query was: SELECT DISTINCT queryTable0.num, queryTable0.value, queryTable1.value FROM index queryTable0, index queryTable1 WHERE queryTable0.path=24 AND queryTable0.type=E AND queryTable1.path=27 AND queryTable1.type=E AND queryTable0.num=queryTable1.num AND queryTable0.nvalue 0.0 AND queryTable0.nvalue = 90.0 AND queryTable1.nvalue 140.0 AND queryTable1.nvalue = 200.0; Eric EXPLAIN of swapped tables in FROM clause says: Eric +-+--+--++-++--+-+ Eric | table | type | possible_keys| key| key_len | Eric ref| rows | Extra | Eric +-+--+--++-++--+-+ Eric | queryTable1 | ref | pathndx,numndx | pathndx | 4 | Eric const | 1152 | where used; Using temporary | Eric | queryTable0 | ref | pathndx,numndx | numndx | 4 | Eric queryTable1.num | 53 | where used | Eric +-+--+--++-++--+-+ Eric 2 rows in set (0.01 sec) The number 1152 comes from that MySQL estimates that there is about 1152 rows that can be found when searching through index 'path' after the constant '24'. MySQL does this estimation by doing a quick lookup in the index tree. The number 53, comes from MySQL guessing that there is about 53 rows with identical 'num' values for each num. You can get a much better guess for the second case if you run 'analyze table' on the table in question. If you want to get the query faster, you have to improve your index a bit. If this is one of your typical queries, I would suggest you do the follwing change to your index: Change the index: KEY `pathndx`(`path`), to KEY pathndx(path, type, nvalue) If there for a 'num' is many rows with a different type, then you should also change the key: KEY `numndx`(`num`) to KEY numndx (num, type) cut Regards, Monty -- For technical support contracts, goto https://order.mysql.com/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Mr. Michael Widenius [EMAIL PROTECTED] / /|_/ / // /\ \/ /_/ / /__ MySQL AB, CTO /_/ /_/\_, /___/\___\_\___/ Helsinki, Finland ___/ 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?
