ANNOUNCE: moodss-16.2
### CHANGES ### --- version 16.2 --- - pages tabs now reflect, by their background color, the crossed thresholds of highest importance in a page - pages tabs now feature a widget tip (balloon) containing up to 3 summaries of the crossed thresholds in a page - implemented colors sequencing (frequency: 1 Hertz) in pages tabs when there are several crossed thresholds of the same importance but of different colors in a page - messenger header (message label at the bottom left of the application window) now also serves as a global active thresholds viewer and implements the new pages tab features (crossed thresholds colors and summaries) but for all the thresholds in the loaded modules, independently of the presence of pages - allowed tables or viewers transfer between pages by move into a page tab, using the internal window manager handles - allowed viewer deletion by move into the eraser, using the internal window manager handles - hopefully handled all cases causing an update of pages tabs colors and widget tips (unloading modules, deleting viewers, moving viewers and tables between pages, updating thresholds, creating first page) - pages cannot be deleted when running in read-only mode - in preferences dialog box, validation would fail when there were no pages displayed - deleting a page between others would make all tables and viewers invisible in the following pages - current values table viewers now support non numerical data - improved anti-vibration code in automatic scroll widgets (please let me know if you see scrollbars in viewers, tables, canvas, help, ... hang the user interface by constantly appearing and disappearing, as in an infinite loop) - when loading from a save file, viewers using summary table viewer cells could show void values, due to a conceptual hole in the summary table restoration code (if you have such dashboards, repair by making sure all viewers show valid values, correct if necessary, then save) - when loading from a save file, cells with thresholds crossed immediately would not be colored on the initial refresh cycle - in thresholds dialog box, update original cell label so that it is correct in all cases, such as when loading from a save file - in global help window, scrolling using the keyboard is immediately enabled - in moomps daemon, removed debug trace - use helvetica font again in HTML widget, used in help, as italics are no longer displayed with an ugly fixed font on XFree 4.2 - use a common background color for all viewers so that free text viewer color is not different from the other viewers on Windows - successfully tested on Redhat 7.3 - in rpm, shared libraries successfully compiled and tested with gcc 3.1 ### README ### This is moodss (Modular Object Oriented Dynamic SpreadSheet) version 16.2. Moodss won in the Best System Admin Technology category (Tcl Tips and Tricks, Valuable Real World Programming Examples) at the O'Reilly Tcl/Tk 1999 Conference. Linux Magazine calls it a lifesaver. Tucows gives it 5 stars (cows or penguins :-). Moodss is a modular application. It displays data described and updated in one or more modules, which can be specified in the command line or dynamically loaded or unloaded while the application is running. Data is originally displayed in tables. Graphical viewers (graph, bar, 3D pie charts, ...), summary tables (with current, average, minimum and maximum values) and free text viewers can be created from any number of table cells, originating from any of the displayed viewers. The display area can be extended by adding pages with notebook tabs. Thresholds can be set on any number of cells. Moomps (shipped with moodss) is a monitoring daemon which works using configuration files created by moodss. Thresholds, when crossed, create messages in the system log, and eventually trigger the sending of email alert messages. Specific modules can easily be developed in the Tcl, Perl and Python scripting languages or in C. A thorough and intuitive drag'n'drop scheme is used for most viewer editing tasks: creation, modification, type mutation, destruction, ... and thresholds creation. Table rows can be sorted in increasing or decreasing order by clicking on column titles. The current configuration (modules, tables and viewers geometry, ...) can be saved in a file at any time, and later loaded at the user's convenience, thus achieving a dashboard functionality. The module code is the link between the moodss core and the data to be displayed. All the specific code is kept in the module package. Since module data access is entirely customizable (through C code, Tcl, Perl, Python, HTTP, ...) and since several modules can be loaded at once, applications for moodss become limitless. For example, thoroughly monitor a dynamic web server on a single dashboard with graphs, using the Apache, MySQL, ODBC, cpustats, memstats, ... modules. If you have replicated servers, dynamically add them to
InnoDB foreign key constraints
Hello list!
I'm having a bit of trouble getting foreign key constraints to work.

I've been reading TFM, and the sentence there must be an index where the

have something to do with my problem, I just find the above a bit... well...
cryptic. If anyone could lend me a hand, I'd be more than happy.

Re: InnoDB foreign key constraints
First of all the referenced key must be on PRIMARY KEY.
But I've seen in your table definition a quite strange thing. You have a
UNIQUE and an ORDINARY key definition on the same field.
Here:
...
UNIQUE KEY `name_id` (`name_id`), - THIS IS THE FIRST DEFINITION
UNIQUE KEY `comp_name` (`comp_name`),
KEY `conn_idx` (`name_id`) - AND THIS IS THE SECOND ONE

Re: InnoDB foreign key constraints
Heya!
You need an INDEX.
Try doing this first :
alter table ip_name_tbl add INDEX(name_id);
And add then your constraint.
EG
mysql SHOW CREATE TABLE ip_name_tbl\G
*** 1. row ***
Table: ip_name_tbl
Create Table: CREATE TABLE `ip_name_tbl` (
`id` int(10) unsigned NOT NULL auto_increment,
`comp_loc` smallint(5) unsigned NOT NULL default '0',
`comp_sub_loc` smallint(5) unsigned NOT NULL default '0',
`ip_stat_dyn` enum('DHCP','STATIC') NOT NULL default 'DHCP',
`IP` varchar(15) default NULL,
`MAC` varchar(17) NOT NULL default '',
`network` enum('Hallinto','Asiakas') NOT NULL default 'Hallinto',
`name_id` int(11) NOT NULL default '0',
`comments` text,
PRIMARY KEY (`id`),
UNIQUE KEY `name_id` (`name_id`),
KEY `ip_idx` (`name_id`)
) TYPE=InnoDB
1 row in set (0.00 sec)
Here's what I get:
mysql ALTER TABLE ip_name_tbl
- ADD CONSTRAINT FOREIGN KEY (name_id)
- REFERENCES conn(name_id)
- ON DELETE CASCADE;
ERROR 1005: Can't create table './koneet/#sql-355_4.frm' (errno: 150)
I know error 1005 with an errno 150 means the foreign key would be
incorrectly
formed, but I can't just figure out what's wrong.
I've been reading TFM, and the sentence there must be an index where the

TWO SERVERS
Everyone, Im just curious if possible, I had two MySQL server...one is the replica of the master server. And to make the database in safe and intact even if there's a hang-up. I use auto back-up using the MySQL dump program. But if master server is downed. All I do is redirect my front-end application to point to the slave server. But I done this manually. All I want is to make it transparent to users in changing from server A to server B. is there an easy way to implement this on Windows platform?...I use the Win32 version of MySQL...and all my front-end is also in Win32 environment...is it possible to build a decision maker between the two server?...if master is up then all loads are directed to master but if the master is dead then automatically all loads are carried by the slave...I just wondering if someone can help me to this...and I highly appreciate any ideas...

Re: Design
I don't quite understand the distinction you are drawing between an image and an image_attrib. To what real-world concept does image_attrib correspond? I'd suggest that the entities in your system are: Image: with fields such as title and [film type stuff] Comment: with a field for the comment text ImageFile: with a field for the file location, as well as cached info from the file itself, like its size or format I'd set up a one-to-many relationship between images and comments, as well as a one-to-many relationship between images and imagefiles (so that you can provide the same image in many formats and sizes). Where you put pricing information is primarily a matter of pricing policy. If you have one policy for each image regardless of size or format (and the actual price is a combination off this policy and the file they actually choose) then you can just put in the image table, if the policy is entirely dependent on the exact size and format you can put it in the file table, and if it is some combination of the two you can put data in both tables. (And I've tried to come up with some excuse for attempting a many-to-many relationship between images and files, but can't get my head around a really sensible system in which separate files for the same image might be included separately in an entirely different image; I guess you could have a 'low-res' or 'jpeg only' version of the image, but I'd think it would make a lot of sense to indirect the image table through a second 'filter' table which performs the many-to-many than to just store redundant copies of the image entries. Regardless, in this case you might have pricing specific to the particular file, but you can no longer store it in the file table, so now you'd have to relate the image (or this new 'filter' table) through yet another pricing table with its own many-to-one relationship to the file table, and that table would be used as the join table for the many-to-many relationship.) -rob On 9/6/02 at 2:11 pm, Jason Soza [EMAIL PROTECTED] wrote: I think I'm in need of a little bit of database design guidance.

is it worth to wait for version 4.1?
Hi all, I'm implementing a bridge between MySQL and Lotus Domino. In our application we realy need stored procedures (triggers). I saw that MySQL does not yet support stored procedures. (This will be one of the features of version 4.1). Is it worth to wait for version 4.1 or should we switch to some other database management system like postgresql (which does support stored procedures)? We realy would like to use mysql. Because the Lotus Domino bridge work perfectly with mysql, but it does not realy work with PostgreSQL. Any ideas here?

RE: InnoDB foreign key constraints
What I think, is that your syntax for creating the primary key is slightly
incorrect. I'm not sure if this is also true vor MySQL but I got teached at
school that a foreign key can only point to the primary key of a table.
Perhaps you can try to do the following:
Create Table: CREATE TABLE `conn` (
`id` int(10) unsigned NOT NULL auto_increment,
`wall_nr` int(6) unsigned NOT NULL default '0',
`hub_switch` varchar(20) NOT NULL default '',
`comp_name` varchar(50) NOT NULL default '',
`name_id` int(10) unsigned NOT NULL default '0',
PRIMARY KEY (`name_id`),
KEY `id` (`id`)
) TYPE=InnoDB
CREATE TABLE `ip_name_tbl` (
`id` int(10) unsigned NOT NULL auto_increment,
`comp_loc` smallint(5) unsigned NOT NULL default '0',
`comp_sub_loc` smallint(5) unsigned NOT NULL default '0',
`ip_stat_dyn` enum('DHCP','STATIC') NOT NULL default 'DHCP',
`IP` varchar(15) default NULL,
`MAC` varchar(17) NOT NULL default '',
`network` enum('Hallinto','Asiakas') NOT NULL default 'Hallinto',
`name_id` int(11) NOT NULL default '0',
`comments` text,
PRIMARY KEY (`name_id`),
FOREIGN KEY (name_id) REFERENCES conn ON DELETE CASCADES
KEY `id` (`id`)
) TYPE=InnoDB;
Notice the foreign key already in the table definition, and off course
creating table `conn` before the other one. If this doesn't work, try
rewriting your foreign key constraint to:
ALTER TABLE ip_name_tbl
ADD CONSTRAINT FOREIGN KEY (name_id)
REFERENCES conn
ON DELETE CASCADE;
* without pointing to which column the key points, just the table.
Btw, why do you have an `id` field, set as NOT NULL and with an
auto_increment, with besides another field `name_id` set as primary key?

how to define my max_connections?
Hello list, I am running mysql-3.23.49 on Linux 2.4.18 for production purpose. Now I want to define a proper max_connections value in mysql. The document said, The maximum number of connects MySQL is depending on how good the thread library is on a given platform.

How do I connect to two databases at the same time
Can you help!! I have two databases on one MySql sever and I would like to transfer certain information from one databases to another. I want to transfer, record by record, from a particular table, after examining the record. How can I open the two databases at the same time? The only way I am able to do this is by 1. opening one database - 2. read a record from a particular table - 3. close the database - 4. examine the records - 5. open the other database - 6. save information and close. 7. repeat the process for all the records. I am worried that this may be in efficient. It there another I could do it?

when will mysql 4.1 be released?
Hi all, I'm implementing a bridge between MySQL and Lotus Domino. In our application we realy need stored procedures (triggers). I saw that MySQL does not yet support stored procedures. (This will be one of the features of version 4.1). Is it worth to wait for version 4.1 or should we switch to some other database management system like postgresql (which does support stored procedures)? We realy would like to use mysql. Because the Lotus Domino bridge work perfectly with mysql, but it does not realy work with PostgreSQL. Any ideas here?

dynamic table width
Hi, I got a table with standard userdata (email, address). I want to be able to provide additional fields (like age, gender etc). Generally I have about 8 standard fields and up to 30 optional fields which may vary. Say something like this: Customer A wants its users to provide email, address and gender. Customer B email, address, age, shopping-preferences. Now Customer A has a million users and Customer B 2 million. And there will be a Customer C..something too :) I wonder what would be the best way to achieve this. I will have to handle a huge number of users in that table. My first guess would be to create a table with 40 columns where most columns are most of the time empty. Does this have an impact on the performance? I cannot predict which customer will use which fields since they should be totally free in their selection. I cannot predict the number of customers either. Is using a single table the best choice?

Re: when will mysql 4.1 be released?
First of all, let me apologize for repeaditly sending my e-mail message to the list. Roger Baklund wrote: I don't know. Not in the nearest future, they have just begun the coding. Oka I don't get it... does it work perfectly with mysql, or do you realy need stored procedures? And how come you consider postgresql, when it does not realy work with PostgreSQL? First you should decide if it works or not with mysql. If it does not, you can consider if it works with postgresql. If it does not, you can consider if it is worth waiting for 4.1, or if you should consider other products. The word worth implies some kind of economic considerations, it is hard to answer without the knowledge of your economic situation. How important is this application for you? Can you afford to not make the bridge in 6-12 months? Can you work on other projects in the meanwhile? (6-12 months is just me guessing, I feel safer with Not in the nearest future.) IBM (Vendor of Lotus Domino) provides a Lotus Notes module called DECS which purpose is to provide a 'bridge' to relational databases like MySQL, Sybase and Oracle. (This goes via ODBC) This 'bridge' seems to work fine with MySQL (and it's ODBC driver). But it does not work with postgreSQL (and the postges-ODBC driver). This is a known bug (and IBM is working on it). We could use MySQL and imlement stored procedures outselves. (Using some scriptlanguages like perl or python). But this is (ofcourse) a lot of work.

Re: dynamic table width
As usual, there are several different approaches, each with different advantages and disadvantages. The simplest approach is just to put all the optional fields in the main table, and each user can decide how many of them they can be bothered to fill in. The disadvantages here are that there is potentially a lot of wasted storage, and adding new optional fields is tough- you've got to change the schema for your main table. If you know exactly which fields each user will use, you can provide each user their own table with its own schema. When that user views the data, you join the main table with their custom table, and when you use whatever user-independent administrative data management tools you've put together you just look at the main table. The disadvantage here is that you're got to create a new table for every user, leaving an 'open' database schema, which is a real maintenance burden. If one particular user comes up with a new optional field, however, you've only got to change their custom table, which in some situations is a major advantage over the previous method (if security is important or the main table is so large that the alter command is a very hefty op you'd like to avoid). I'm not sure this is right for you if you think you'll have more than a handful of users, although there are a great many variations on this theme (one or a small number of 'secondary' tables) that might be appropriate. The most flexible approach is to abandon type safety altogether and use a 'property list' table with 'name' and 'value' fields, along with the primary key of the entry in the main table. Then users can create any set of optional fields they want, and there is no administrative maintenence burden. The disadvantages, of course, are that you'll probably make the field values be 'text' or something, so applying spiffy date or numeric operations to them is not so simple, and that the abundance of JOINs necessary to replicate the original layout, while not necessarily hurting asymptotic complexity, can definitely slow down your database ops. -rob On 10/6/02 at 2:25 pm, Peter Romianowski [EMAIL PROTECTED] wrote: Hi, I got a table with standard userdata (email, address).

I have configured a cron entry to execute this every one minute as
follows.

I increased the size of mysqld.log to 1200k but rotation didn't
happen. The following was the output
reading config file /root/mysqlrotparams.conf
reading config info for /var/log/mysqld.log
Handling 1 logs
rotating pattern: /var/log/mysqld.log 102400 bytes (5 rotations)
empty log files are rotated old logs mailed to [EMAIL PROTECTED]
rotating file /var/log/mysqld.log
log does not need rotating
Can anyone help me in this regard ???

RE: Rotating mysqld.log
You need to get logrotate to flush-logs otherwise mysql will still write to
the old file.
eg add after the create 0644 mysql mysql line:
postrotate
if test -n `ps acx | grep mysql`;then
/path/to/mysqladmin -u logflusher -ppassword flush-logs
fi
endscript
Assuming a mysql users called logflusher with password password has the
flush privilege.

Re: No Warnings after changed data
- Original Message - From: Charlie Thunderberg [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 10, 2002 8:23 AM Subject: RE: No Warnings after changed data Hello, I think that my problem boils down to the unimplemented getWarnings() method in the mm. JDBC driver. If it was implemented, I could detect if the data was e.g. truncated. Can anybody help me find an implementation for this method? The reason that it's not implemented in the JDBC driver, is that MySQL issues warnings on every single query, except it's called Extra Info, and it's not always a warning. The overhead in parsing these messages (which happen to be different depending on the locale installed, complicating matters even further), has not been asked for by users of the driver, yet. In any case, what the server returns in the case of a real warning will not give you _any_ diagnostics on a warning, just that something happened (e.g. see http://www.mysql.com/doc/I/N/INSERT.html at the bottom of the page), so it's not helpful in diagnosing that data has changed. The protocol for MySQL 4.1 will have a way to retrieve only warnings, and hopefully a more descriptive warning message implementation. -Mark - 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: 45 seconds
Hello, The reason that it takes so long is because you are using regexp on a function to join the table. That means that MySQL can't use indexes for that column. If you run an EXPLAIN on the query you will see that is true. To speed up the query some you could add an index on new_raw_log(GID,SID). That will at least allow some filtering using an index and might give some speed up, depending on how many matching results there are. The ideal case would be redesign your database to be able to join the tables using some other mechanism than a regular expression statement which MySQL will then be able to use indexes to join on.

RE: Not using indexes???
E.g. the non-equivalence operator is the same. MySQL will use indexes for foo0, but not foo0, which ask for the same result (presumed foo is an unsigned column). Perhaps I was a bit unclear... Using foo 0 does *NOT* use an index. Using foo 0 AND foo somevalue *DOES* use an index. As Erv did not know why this could help: It uses a different operator than IS NOT NULL, namely greather-than. One, that MySQL supports to make use of indexes. Again, merely using greater than by itself produces results identical to using IS NOT NULL. -JF - 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?

hello .
i use php 4.12 + mysql 3.23.49 on linux .
i've developed a online testing(quiz) -aplication that now is expected to
behave somehow different from what i've had in mind at the begining . More
exactly :
i have 3 tables (MyIsam):
1. tests (id,name,desc)
2. questions (id,id_test_fk,desc)
3. answer(id,id_q_fk,desc,points) .
i want to copy a question from one test to another .
If i knew that from the start , i would have designed the tables differntly
, but that's another problem .
the point is i'm trying to do a 'quick_and_dirty' patch like this :
--
set @test_id=$test_target;
set @q_id=$qid;
create temporary table q_temp as select * from questions;
create temporary table ans_temp as select * from answers;

select @last:=LAST_INSERT_ID();
insert into answers select '',@last,score,description from ans_temp where
id_question_fk=@q_id;

where $test_target and $qid are given from php .
my problem is that this query works and dows what is expected when run from
mysql ,
but NOT from php . No error , nada . I even tryed to do dirty thing
(shell_exec('mysql -u user -p password database /tmp/qry.txt')) where

RE: when will mysql 4.1 be released?
I guess it's a question of semantics, but I would consider a stored procedure, in general, any series of commands to be executed 'in' the database engine. Postgres, for instance, allows stored procedures to be written in a number of different languages. Commercial engines have similar capabilities. I would think that a stored procedure would not be required to do much of anything with SQL. SQL would simply be a way of invoking it. Cheers. -Dana -Original Message- From: Svensson, B.A.T.

Indexing on a DATE field/bizarre speed issue with a LEFT JOIN?
Hi List, I sure do appreciate this list. I'm stumped on the following query: SELECT head.po FROM head LEFT JOIN line ON (head.sn=line.snHead) WHERE head.po 1 AND line.dateETA='2002-06-10' LIMIT 50 As is, this query is very fast (0.01 seconds when there are 25,000 records in 'head', and 50,000 records in 'line'). However, when I change the query to search on line.dateETA = or even = [somedate], the query takes a long time to return (2-3 seconds). The line.dateETA field is indexed. And, for both = and = queries, EXPLAIN returns the same information. The only thing I can think of is that NULL values are allowed in line.dateETA, and about half the values are NULL (22,000 lines). However, I tested changing the line.dateETA field to NOT NULL, and I didn't get any better performance. Is there a known speed issue in searching on date fields with = versus =?

I have a problem....
We are running mysql on a red hat box. We replicate a single database twice, once on another red hat box(thank whatever is holy), once on a winnt box. The winnt box cares not for case sensitivity, so it created all our table names in lower case ( our standard is to use CAPS for tablenames ) ( i knew this was an issue, but I forgot about it when i got a new toy to play with: the nt server ) Now, I did a dump to a development red hat box, and it created all the tables in lower case ( which is useless since our application is geared to the uppercase table names ) Does anyone have a solution or work around for this ? I briefly considered creating a script for the linux box to rename the files but thought I should ask if there was any other way to do this...

Re: Timezone question
Yes. MySQL attempts to get the current time zone from the OS, but this can be overridden by setting the TZ variable. (The manual suggests doing this in the safe_mysqld script; there's already code in there for setting it from a command line argument.) Valid settings of TZ are technically not time zones but rather time locales, which on linux at least correspond to paths relative to /usr/share/zoneinfo, such as America/Los_Angeles or US/Pacific. Note, however, that this causes problems since most locales actually refer to two time zones- one daylight and one standard- so MySQL will sneakily change time zones behind your back without telling you. If this will cause you problems I suggest staying away from these nefarious locales and using one of the single-zone locales in Etc/, such as Etc/GMT-8. -rob On 10/6/02 at 7:20 am, Kevin [EMAIL PROTECTED] wrote: Hello, I am using the now() function to insert the current timestamp in a mysql table.

MySQL AB: Need documentation clarification
MySQL AB staff: 1) The recent discussion on the subject Not using indexes??? brought to light an opportunity for interpreting the documentation in contradictory ways. The page http://www.mysql.com/doc/M/y/MySQL_indexes.html does not mention the IS NOT NULL comparison operator, nor does it mention the inequality () operator. This allows the reader to believe that since those operators are not mentioned, it goes without saying that they never use an index. It also allows the reader to believe that since each is simply the negation of a comparison whose index use is specifically documented, it goes without saying that they also use an index. Which of these interpretations is the truth that goes without saying, and which is the error that should be obvious even to the uninitiated? Or (removing my tongue gingerly from my cheek), what is going on here? 2) Also, the discussion of ANALYZE TABLE at http://www.mysql.com/doc/A/N/ANALYZE_TABLE.html leaves the user of InnoDB tables in limbo. If this doesn't work on InnoDB tables, what takes its place, or why does its place not need to be taken?

what do you mean it doesn't do anything? you should be able to set it on the command line as: --set-variable=max_connections=200 or you could edit the my.cnf file that mysql is using when it starts-up. if you can't find the my.cnf, then you should create one. here is a link to the manpage and some default entires on mysql.com: http://www.mysql.com/doc/O/p/Option_files.html either way, you can check to see if the max connections has been updated by running the below command at the mysql prompt: show variables; katen At 06:05 PM 6/10/2002, Rekha Das wrote: Hi all, I am trying to set max_connections to 200 on my server.

Oracle roles in MySQL?
Does MySQL offer anything to take the place of Oracle's roles? I'm especially interested in the ability, when adding a new table (or a new view, in the future) to the database, to be able to grant the desired access to everyone who ought to have access, without having to enumerate those people. Specifically, GRANT SELECT, INSERT ON my_new_table TO data_tech; GRANT SELECT, INSERT, UPDATE, DELETE ON my_new_table TO research_assistant; lets you grant the necessary permissions without having to know who the research assistants are this semester, and who is on the data entry staff at this moment. Is there a similar facility with a different name in MySQL? If not, is it planned?

Re: sql query(group by + order by)
do a select patient_id,treatment_date from patient_treatment_history order by treatment_date desc limit 1; I am not sure but max(treatmen_date) might work too as such: select patient_id, max(treatment_date) from patient_treatment_history group by treatment_date; In your original query the group by clause is causing undesired results. - Original Message - From: lorenzo.kh [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 10, 2002 6:53 PM Subject: sql query(group by + order by) Hi, I got a table named patient_treatment_history Below is some of the records inside the table. patient_id,treatment_date,charges 1014,2002-01-28,20 1001,2002-02-02,100 1026,2002-04-08,74 1001,2002-04-15,85 1014,2002-05-05,50 1030,2002-05-16,125 1030,2002-06-18,180 1001,2002-06-25,125 I try to retrieve the last visit date for each patient using this query: select patient_id,treatment_date from patient_treatment_history group by(patient_id) order by treatment_date desc.

Here's something
Hi all. This is my first post here, so please be patient with me. I dont know if theres a program already made that does what I need, so I dont have to reinvent the wheel. Im using PHP MySQL to make most of the web sites and web-based Corporate Intranets programs. What I need now, is to make a program that can keep track of a social club affiliates and their monthly payments. Also keep track of the teachers and classes hours. Because Im taking my first steps into RDBMs, I would appreciate very much all the help I can get in order to create the perfect DB structure. What I have in mind, is something like this: Table users (user_id, affil_number, last_name, first_name, etc ) Table teachers (teach_id, last_name, first_name, etc ) Table classes (class_id, name, hours) Table teach_clases (class_id, teach_id) Table payments (payment_id, user_id, month, year, main_fee, class1_fee, class2_fee, etc ) What I need to do is show, as an example, the total payments made by affiliate # 0345 in the last 12 months. Other example would be to show all the persons who hasnt paid last month fee. Is what Im thinking correct or should I consider doing some other table or perhaps changing one thats already made?

Re: Here's something
Looks okay to me except table teach_classes should have a unique id for each record. teach_clases (taught_id, class_id, teach_id) Over the long term, the same class probably will be taught more than once and the same teacher probably will teach more than one class so neither class_id nor teach_id would remain unique in the table for classes taught. - Original Message - From: César L.

Re: MySQL AB: Need documentation clarification
In the last episode (Jun 10), Erv Young said: MySQL AB staff: And the thousands and thousands of regular people reading this list :) 1) The recent discussion on the subject Not using indexes??? brought to light an opportunity for interpreting the documentation in contradictory ways. The page http://www.mysql.com/doc/M/y/MySQL_indexes.html does not mention the IS NOT NULL comparison operator, nor does it mention the inequality () operator. This allows the reader to believe that since those operators are not mentioned, it goes without saying that they never use an index. It also allows the reader to believe that since each is simply the negation of a comparison whose index use is specifically documented, it goes without saying that they also use an index. Indexes are only used if they significantly reduce the number of reads required vs a full table scan (I believe 30% is mysql's threshhold). An IS NOT NULL clause may very well use an index if almost all of the records have NULL in that particular field. A != clause is a bit harder, since that basically devolves into field ## OR field ##, and I don't think can optimize that. -- Dan Nelson [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 mysql-unsubscribe-##L=##[EMAIL PROTECTED] Trouble unsubscribing?

RE: Here's something
Well... thanks Cal Day. Your thoughts are brillant. It makes me very proud that more experienced DB designers think I'm doing great. About the normalization rules, I have them inside the PHP and MySQL Web Development book, written by Luke Welling and Laura Thomson, but since my native language is Spanish, it's very hard for me to keep up with understanding after reading 200 pages in a row (kinda in a hurry here ;-) Well, thanks for your help and for letting me know that I can count on all of you to make my life easier.

Aracena; MySQL General Asunto: Re: Here's something Wow, for your first shot, you've got a very normalized database. GOOD JOB! The only thing wrong is your payments table. It needs to be more like: payment - payment_id = class_id user_id date amount - - (The primary key is the combination of class_id and userID) Then you could : * join it with the classes table to see how much each class brought in, * Join it with the users table to see how much each person has paid * join it with the classes to get a roster of attendees. * join it with the classes where amount is null to get a list of deadbeats. * join it with teachers and classes to see how much each teacher is grossing. You get the idea. A couple of rules I always go by: (They are my rules, others may debate them but so far nobody has convinced me to change them...you'll come up with your on as you go on) * All tables have a primary key of tableNameID (or in your case tableName_id...but I hate [_]!) * Table names should be singular. this way a person does not have a people_id...he/she has a person_id. :) Go hit google.com and search for the 5 rules of data normalization. You are already doing most of the first 3 now but they will help you formalize what you are doing.

G'day César I have a problem when posting. The thing is that every time I post to the mailing list, I get an error saying that the message could not be delivered but it does indeed. It's getting delivered to the list OK but one of the subscribers to the list is rejecting it. I've seen this a fair bit from MySQL lists and it can be for a number of reasons - eg. people's Hotmail accounts filling up or a mail server's automated rules rejecting it for one reason or another.

Problem with Escaping quotes
I'm writing some routines which generate SQL queries, and I'm trying to
keep things generic. As such, I have a routine to SQL Escape some text,
such that it can be used in a query without breaking anything. This
routine predominantly consisted of preceeding all single quotes (') with
a backslash. ie; \'
However, this method of escaping does not seem to work with some other
DBs (eg; Oracle), so it breaks when talking to other DBs. I changed my
routine to instead replace all single quotes (') with two single quotes
(''), which seems to be a more standard way of doing things. The routine
now works for Oracle, and mostly works for MySQL, but...
The problems occur when you need to escape something like, for example: \'
If we use the double-quote method, then escaped, this becomes: \''
For a DB which only supports the double-quote technique, internally
unescaping this replaces each double-single quote with one single quote: \'
For MySQL, however, it sees the \' as a single quote, and the second
single quote as closing the string (which means anything after it is
seen as SQL code).
Any ideas on how I can resolve this problem, preferrably without
resorting to custom Escaping routines for different DBs?
