Hi, All. Help me to understand why such different speed of two queries. These queries do the same and differ only in superfluous information (marked by red). Speed of the first is 0.37 second. Speed of the latter is 3.95 second.

Full text search gotchas
We're having quite a lot of difficulty with MySQL's fulltext search. The problem is that it does partial matches. E.g., john matches johnson. Thus a match of author against dickens takes about 0.09 seconds with a 700,000 record table, but a match of a shorter word takes a good deal longer - a four-letter word takes several seconds. Does anyone know whether it's possible to change this so substring matches (such as john against johnson) are NOT made? (Perhaps someone has a patch or a suggestion as to how to make this work.) Also, having incidentally changed ftdefs.h to match 3-letter words, is it now necessary to rebuild the fulltext indexes? = Do You Yahoo!?

Re: Couldn't select database
hey bob,
thanks for getting back to me - here's the full set up
i have a pc running windows98, apache, php and mysql. it sits on our
ethernet network and i connect to it via my mac using the ip address i have
set up in the network control panel on the pc. i use the mac for building
and the pc for web serving/ testing.
first error to report: when i start up from the command line, change into
the mysql/bin directory and type:
mysqld --standalone
i get the error 'can't initialise InnoDB as 'innodb_data_file_path' is not
set'. however, this doesn't seem to effect the general running of mysql.
i created a data base with the mysqladmin programme called 'test'. i then
create a host, user and password by typing the following at the mysql
prompt:
use mysql
insert into user (host, user, password) values ('192.168.254.204', 'jake',
password('twentyeight');
i then exited and used the mysqladmin to flush-privileges and tried to
connect to the database using a simple php page which checks the connection
and then use's it to connect to the test database. this all works.
then i created a 2nd database called 'guest' to start developing a guestbook
mysql backend with a php front end.
when i try to connect to this using the same host, user, password my php
test script seems to connect and cant find or connect to the database.
from what i have read and the responses i have had, it seems you have to
re-enable the host, user and password for the new databases you create but
the code that people are kindly offering up seems to have different commands
in it and to be truthful my skills are not advanced enough to full
understand how to enter it correctly.
any more info that people can chuck my way would be great.
cheers,
jake

Hi Jake,
Your problem appears similar to a problem I had but...
you aren't providing quite enough information..
Are you working as a user on the same local host or
are connecting across a network?
To eliminate a MySQL problem ( so you can concentrate
your efforts on PHP code) try to connect directly from
the command line with MySQL as follows..
#root$ mysql yourdatabasename -h hostname -u username -p password
You can eliminate -h and -p if your on the same machine without
password.
See if this will connect..

Tables exceeding 2gb
Hi, I have a Linux machine (Linux cartman 2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686 unknown) that is running MySQL 3.23.38-log and now I have a table that is getting VERY near to the ext2 filesystem limitation of 2gb. Exact size of the table is: 2039867196 :) So my question is. What happens? Does mysql write into another file and automatically merge them on the fly or does the table stop or what? Also what suggestions do you have concerning this matter? regards, Gudmundur
HELP NEEDED: Problems with SELECT in combination with HAVING
Hello there - I have this weird problem using MySql (version 3.23.39). It seems that MySql interpretation of a SELECT statment using HAVING is completely random. I have a table called RobotRun which stores information about when a robot has been running (start, stop and the id of the robot). This translates to columns: runId (primary key), robotId (the id of the robot), startTime and endTime. A robot can run several times during its life time, thus several records will appear in RobotRun for the same robotId, however, each row will always have a unique runId. The purpose of the SQL is to produce one RobotRun row for each robot, with the added restriction that it is only the row with the newest startTime value that gets selected. Now if I do the following SQL things start to get strange: SELECT robotId, startTime, max(startTime) as crit FROM RobotRun WHERE startTime = '2001-06-26 00:00:00' AND endTime IS NOT NULL GROUP BY robotId HAVING startTime = crit This query produces 321 rows. Setting the startTime to '2001-06-25 00:00:00' produces 707 rows, which is correct and expected since the input set is larger. NOW: Setting the startTime to '2001-06-24 00:00:00' produces 21 rows What is going on. I cannot see how this is possible. The input set is only getting larger. The number of rows involved in the table is in the vicinity of 5. The theoretical maximum number of rows produced from the SQL is in the neighbourhood of 5000 rows. That shouldn't be a problem. I have also tried the following statement with the same result (problem): SELECT robotId, startTime FROM RobotRun WHERE startTime = '2001-06-26 00:00:00' AND endTime IS NOT NULL GROUP BY robotId HAVING startTime = max(startTime) Any help would be appreciated.

Re: Full text search gotchas
Hello Matthew I would be quite interested to know how you managed to make a partial search. I built a search engine recently using fulltext, and partial searches would never work. Say I type in child, I would never get any results with children. This is quite weird since you seem to want it the way I had my search, but I didnt change any of the settings (left everything at default), and still had only exact matches in the output. If you find out how to change it either way, please let me know. I thought it would not be possible to use partial searches. Cheers, Nessi *amazed* ;) PS: Maybe its coz my database was very small?

auto-increment sequence question
Hello everybody, I thing, that I have a problem that needs a sequence and that auto-increment can't do the job this time. I already consulted the manual and the mailarchive. I saw several different proposals, now I'm a bit confused and don't know exactly what the rigth way is to do it. Could somebody please clarify the following? We are using ISAM tables on mysql 3.22.32. We have an id-column but the id will be generated out of two different ranges. Example: all VIP-customers will get an id from 1000- and normal customers from 1-999. So, I think the only way to solve this is a sequence table. Lets take a single row, integer value for holding the sequence: CREATE TABLE sequence( id int4; ); My question is this: Is this the best way to get and evalute the sequence? LOCK TABLES sequence WRITE; UPDATE sequence SET id=id+1; SELECT id FROM sequence; UNLOCK TABLES; Thanks Gunnar von Boehn - 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?

If you really want words, use rlike and \...\ (assuming that MySQL can do egrep-like escapes).

Re: Full text search gotchas
Hello, thanks for your reply. I was wondering...I thought the LIKE function is only for single words? I have to admit I never tested it and started right off with fulltext option. So would following work then... Lets assume one entry in somefield is: The children are playing on the play-ground and I want to search for it using LIKE: SELECT * FROM yourtable WHERE somefield LIKE '%child%'; Would that then give me above entry in the output?!? Sorry if this is a stupid question, its just that I understood it from the manual that you can only search for a word not a text with LIKE. Cheers, Nessi At 13:13 26/06/01 , you wrote: Partial searches can be done with 'LIKE', i.e.: SELECT * FROM yourtable WHERE somefield LIKE '%searchstring%' The '%' is MySQLs wildcard here, so if you only want strings starting with your searchstring, use 'searchstring%' Regards, Sebastiaan J.A. Kamp Hello Matthew I would be quite interested to know how you managed to make a partial search. I built a search engine recently using fulltext, and partial searches would never work. Say I type in child, I would never get any results with children. This is quite weird since you seem to want it the way I had my search, but I didnt change any of the settings (left everything at default), and still had only exact matches in the output. If you find out how to change it either way, please let me know. I thought it would not be possible to use partial searches. Cheers, Nessi *amazed* ;) PS: Maybe its coz my database was very small? Only had about 200 entries when I started off? At 13:11 26/06/01 , you wrote: We're having quite a lot of difficulty with MySQL's fulltext search. The problem is that it does partial matches. E.g., john matches johnson. Thus a match of author against dickens takes about 0.09 seconds with a 700,000 record table, but a match of a shorter word takes a good deal longer - a four-letter word takes several seconds. Does anyone know whether it's possible to change this so substring matches (such as john against johnson) are NOT made? (Perhaps someone has a patch or a suggestion as to how to make this work.) Also, having incidentally changed ftdefs.h to match 3-letter words, is it now necessary to rebuild the fulltext indexes? = Do You Yahoo!?

full outer join?
According to the MySQL documentation, it doesn't currently support full outer joins and won't do in the immediate future. Does anyone have any suggestions for a workaround? I need to join three tables, only one of which has a common identifier with the others, and produce a result which shows not only the matching information (eg, where A.first_id = B.first_id and A.second_id = C.second_id), but also find any rows in either B or C that don't have a matching row in A, as well as any rows in A that don't match either B or C. Starting with A, I can easily show rows that don't have a corresponding match in B or C by means of a left join, but I can't work out how to get the reverse information in the same select. Any ideas? Or am I missing something obvious? Mark -- With sufficient thrust, pigs fly just fine.

delay times, threads
Running Unix, Apache, MySQL and PHP, should I worry about delay times, and will the server always present the user with the latest database update (after a possible delay)? Suppose a user can add a new row to a database in a PHP page with a form, and after submit, the next page he will see is a page displaying part of the same database, hopefully with his new row on top. Questions: A) will he always see the new data which he entered just a second before? B) How much delay could there be. In other words, how multi-tasking is PHP; will it run the next script line, even when a previous line (a MySQL query) has not been completed yet? And will MySQL execute a next (non-update) query, when the precious one is not done yet?

Simple Graphical Interface

3.23.39 Solaris binary on Solaris 2.6 (sparc)
A simple question... I noticed that the newer MySQL binaries are listed as being for Solaris 2.7+ (mysql-3.23.39-sun-solaris2.7-sparc.tar.gz) I want to run it on Solaris 2.6, will this run OK?? There didn't seem to be any docs relating to this (would be nice to see these kind of comments in the binary README file). I only have one system (and that is production) so I can't really afford downtime for testing so I need confirmation from someone that it will work OK. I just had a failed attempt at running a binary I had compiled myself, so I thought it would be best to use the standard binary. The system is: (uname -a) SunOS 5.6 Generic_105181-17 sun4u sparc SUNW,Ultra-2 I will be upgrading from binary Distrib 3.22.25, for sun-solaris2.6 (sparc), yes well overdue! Thanks for any feedback.

Re: HELP NEEDED: Problems with SELECT in combination with HAVING
Try SELECT robotId, max(startTime) as crit FROM RobotRun WHERE startTime = '2001-06-26 00:00:00' AND endTime IS NOT NULL GROUP BY robotId This should return the robotId and the most recent startTime labeled 'crit' for all records specified in the where clause. And have a look in the manual for the group by statement - since this statement works like a enhanced 'select distinct' query it will produce ill results applied to non unique combinations in the select and group by statement. I suppose that¹s the case for your 'robotId, startTime' pair. If I got this wrong forgive me it was first thing in the morning. Hannes On 6/26/01 4:05 AM, Thomas Michael Koch [EMAIL PROTECTED] wrote: Hello there - I have this weird problem using MySql (version 3.23.39). It seems that MySql interpretation of a SELECT statment using HAVING is completely random. I have a table called RobotRun which stores information about when a robot has been running (start, stop and the id of the robot). This translates to columns: runId (primary key), robotId (the id of the robot), startTime and endTime. A robot can run several times during its life time, thus several records will appear in RobotRun for the same robotId, however, each row will always have a unique runId. The purpose of the SQL is to produce one RobotRun row for each robot, with the added restriction that it is only the row with the newest startTime value that gets selected. Now if I do the following SQL things start to get strange: SELECT robotId, startTime, max(startTime) as crit FROM RobotRun WHERE startTime = '2001-06-26 00:00:00' AND endTime IS NOT NULL GROUP BY robotId HAVING startTime = crit This query produces 321 rows. Setting the startTime to '2001-06-25 00:00:00' produces 707 rows, which is correct and expected since the input set is larger. NOW: Setting the startTime to '2001-06-24 00:00:00' produces 21 rows What is going on. I cannot see how this is possible. The input set is only getting larger. The number of rows involved in the table is in the vicinity of 5. The theoretical maximum number of rows produced from the SQL is in the neighbourhood of 5000 rows. That shouldn't be a problem. I have also tried the following statement with the same result (problem): SELECT robotId, startTime FROM RobotRun WHERE startTime = '2001-06-26 00:00:00' AND endTime IS NOT NULL GROUP BY robotId HAVING startTime = max(startTime) Any help would be appreciated.

Re: Got timeout reading communication packets
The above only implies that your program exited without calling mysql_close(). Nothing to do with your problem. But.. why would the console be reporting this? Ie, I'm getting the same result (same error in the error log, same truncation) when I manually pipe the query to the mysql console. (Note that the errors are coming from localhost; the actual script is run from a client). Shouldn't a direct console query terminate the connection to the database after proper completion? But, as I told you , you did not quote string constants. And shoot out your resulting string to some file for inspection. That might help you find your error. See previous emails.. I've been doing this.. the query looks sane; no \0 characters, no odd binary data, nothing out of whack where it truncates (ie, no renegade ' etc.). Because running the query through the console with no intervention of the c api causes the same result I'm finding it difficult to believe it's an issue with the code itself unless it has something to do with the string itself (ie.. there is some unknown character in there). But, that seems unlikely since the code to generate the query is fairly straight forward.. just dump a bunch of tab delimited ints groups of which comma delimted into a string. The query just looks like: REPLACE into reflectivity.measurement_extended_data set content_typeID = 7, contentID = 121529, arrayID = 0, positionID = 1, testID = 1, iteration = 0, test_locationID = 1, date_added = 993165848, added_by = 18, data = '396 601 12011801,0 191 191 191 191 190 189 188 188 188 188 188 187 191 191 191 191 192 snip/snip; It just happens to be several MB large.

Re: DISTINCT
Hi Tom, The solution to your problem could be simple if the redundancy is across all fields. Then you could simply issue a CREATE table distinct_records SELECT distinct field_1,.field_last FROM table_duplicate_records WHERE 1=1; Or CREATE table distinct_records SELECT field_1,.field_last FROM table_duplicate_records GROUP BY field_1,.field_last; The latter will not work properly if one or more of the fields selected is not identical for identical combinations of the remaining fields. Otherwise if you have one or more fields that is not identical among a group of otherwise (apart from those fields) duplicate records) you must decide if this difference matters to you or not. If they don¹t matter just select all where the duplicates are identical. Make sure that the fields in the select and group by part are the same. Example table_duplicate records field_1 field_2 field_3 a b c a b c a b d f g h f g h d j k k i o CREATE table distinct_records SELECT field_1, field_2, field_3 FROM table_duplicate_records GROUP BY field_1, field_2, field_3; table_distinct_records field_1 field_2 field_3 a b c a b d f g h d j k k i o Got the idea?

RE: Lat/Long storage?
NUMBER(8,5). You'll need around 5 digits after the decimal point. (Think GPS accuracy == 10 meters for high-grade, 100 m for dumbed-down civilian use. At the equator, that's 0.9 or 0.0009 degrees respectively. At higher latitudes, that'd be correspondingly less.) If you value accuracy, DON'T USE FLOAT. Float has only 6-7 digits of accuracy, which, if you take out the 3 digits before the ., leave you with only 3 decimal places after (== roughly 1 km - too rough). Use Double (which would be 8 characters), or use number (8,5) or number (7,4), which are approximately the same size. The latter are easier to work with for display purposes, the former for computation purposes. Take your pick. If you use NUMBER(#,#), you should make sure that internally, you convert them directly to and from double to preserve the accuracy of the numbers. -Original Message- From: Nelson Goforth [mailto:[EMAIL PROTECTED]] Sent: Monday, June 25, 2001 2:03 PM To: [EMAIL PROTECTED] Subject: Lat/Long storage?

A single table with a single column won't do it. Try this, which will work for any number of sequences. First, create a table to hold your sequence numbers: # Create a table to be used for multiple sequences CREATE TABLE sequence ( nameCHAR(20) NOT NULL PRIMARY KEY, seq BIGINT UNSIGNED NOT NULL ); name identifies your sequence. It's a PRIMARY KEY for fast lookups. seq is the current sequence value for a given sequence. Next, intialize your sequence counters to one less than the first number you want to use in each sequence: INSERT INTO multiseq (name, seq) VALUES(vip,999); INSERT INTO multiseq (name, seq) VALUES(normal,); To generate a new VIP sequence number, do this: UPDATE multiseq SET seq = LAST_INSERT_ID(seq+1) WHERE name = vip; SELECT vip, LAST_INSERT_ID(); To generate a new Normal sequence number, do this: UPDATE multiseq SET seq = LAST_INSERT_ID(seq+1) WHERE name = normal; SELECT normal, LAST_INSERT_ID(); LAST_INSERT_ID() with an argument creates a value that can be treated just like it's an AUTO_INCREMENT value. That means you can call LAST_INSERT_ID() without an argument later in the current session to retrieve the value you generated. This also has the advantage that you don't need to set up any locks. The table can be extended to provide more than two sequences simply by inserting new rows. (This is one way to main hit counters for a bunch of Web pages using a single table, for example - although you'd want to use a longer name column in that case...)

PLEASE READ: Porting Windows VC++ MySQL Proggie to Linux\Unix
I appreciate that this might be a bit off topic but any help would be appreciated. I need to port this program (attached) to the Linux environment. This is the first program I have attempted to port. Has anyone ever had to port from Windows to Linux\Unix, and if so how did it go and what tools did you use. I have downloaded cygwin for windows, is this going to be any use? The program itself simply uses the mysql++ API library to connect to the server, run a query and then exit. Parts of the program that might cause me problems are the headers I think, because what is Linux for: #include iostream #include iomanip #include include\mysql++ Please I really just need a starting point; someone to say you need this tool you can download it at www.thistool.com. I am a complete newbie to porting (though not to mysql nor working with linux or windows programming) Hopefully when I become proficient with this program I can move on to bigger and greater projects. ***I would appreciate ANY input*** Sorry once again if this is off topic!!

Re: preventing duplicate entries
-- Original Message -- From: Pete Kuczynski [EMAIL PROTECTED] Date: Tue, 26 Jun 2001 13:19:02 -0500 I want to prevent duplicate entries into my mysql database which holds invertory of all network eqpt at my site. Engineers access it thru netscape and the query insert is done via pdp [below]. I will place the script into php, any pointers on this would be appreciated. Why not make your inventory identifier field a unique index: ie: alter table inventory add unique itemid (itemid); Now, whenever someone tries to create a duplicate item identifier, MySQL will issue an error, which your script can capture. I don't use PHP, but do use VB through MyODBC, and this is how I catch unwanted duplicates. - 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: preventing duplicate entries
My primary key field is a auto incremented index, the field I want to make unique, or to say, prevent duplicates in, is the hostname field, which has, hostnames of devices. Is the key word UNIQUE then? Not all of the devices have hostnames assigned to them, like terminals, so the hostname field is blank in many cases. If I make that field UNIQUE, will that cause a problem, with multiple blank fields? Thx! Pete Kristopher Briscoe wrote: What does your table definition look like? What fields are you looking to make unique? All you need to do is set one or multiple combined fields to UNIQUE or Primary keys. This will prevent duplicats. Another way would be to query the table for the information that is going to be inserted and see if you get a row returned. If so, then let the FE know. I would combine both methods for optimal assurance. On another note, I have been very interested in working with DHL. At one point I was speaking with someone in your HR department, but they have seen departed.

Re: CF and MySql?
There are many ways to do this - I'm assuming you want to do this on an Windows box. One way is through MyODBC. It's an ODBC driver that you can install on your server, available from the MySQL web site. From there, all you have to do is create a new DSN, either through the CF Admin or Windows. You can then reference this DSN just like you would any other ODBC connection.

If you are using Cold Fusion server, yes they will work.. You have to download MyODBC from www.mysql.com install it.. and then set it up in the ODBC control panel (assuming you are using windows). Then you should be able to see the mysql databases as a datasource in the Cold Fusion admin page.

The problem that i've run into is, I can't seem to find any documentation on how to force an AND search with in MATCH AGAINST syntax, As far as I can tell this is `OR' only.

RE: Optimizing MySQL
I'm not an expert, but I've never heard of a db getting slower after an index rebuild. It's possible that's just a red herring. You've been speaking generally about things being slower, I'd suggest you get specific. Track down the queries are slow now, use EXPLAIN on them to see what indexes that are using (or not). There a way to log slow queries in MySQL, that might help. Perhaps usage has just shifted and there are now a lot of writers and readers to the same table - run mysqladmin pr and look to see if some servers are waiting due to table locks. mysqladmin -i3 pr is good to do continuous monitoring. -bill - 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?

lower_case_table_names issue
Hi to all, I'm new to linux and mySql (about 5 days and nights :)), I have mandrake8.0 that provide a version of MySql which I'm trying to use from a VisualBasic application (on win2000), I connect to my database on MySQL using MySqlODBC, and everyting goes OK, except the table names wich I need to be case insensitive on queries, after reading the manual I found that I could use the variable 'lower_case_table_names=1' to this prupose. I set the variable, but when I try to select something MySQL returns a error 'database.MyTable does not exist', but she exists with name 'mytable'. If someone could help!

Re: lower_case_table_names issue
Did you convert the table/column names to lower case? If lower_case_table_names is=1 MySQL will convert all table names to lower case on storage and lookup ... but you need to first convert your old table names to lower case before starting mysqld. If you have not done so, you should run an ALTER query to change them to lower-case ...

Re: Conversion from Access JOIN syntax to MySQL JOIN syntax...
As it is such a big query, I don't have time to look at it for you but it may be easier if you convert the RIGHT JOINS to LEFT JOINS for starters. The manual does recommend LEFT JOINS, mainly for portability.

Perl Script: MySQL Slow Query Log Parser
I wrote a perl script that will parse slow_queries logs, and output some useful information. It's kind of hard to explain, but I'll try. I wanted to see what queries were taking a lot of time, and how often they were happening. I wrote a perl script that parses the log files, ignores queries that take less than n seconds, and normalizes the queries and reports the info for each queries sorted by query occurance. 'normalize' meaning... this... SELECT * FROM ween WHERE pandy_fackler = 1; SELECT * FROM ween WHERE pandy_fackler = 15; becomes... SELECT * FROM ween WHERE pandy_fackler = XXX; this... SELECT names FROM things WHERE name LIKE '%wazoo%'; SELECT names FROM things WHERE name LIKE '%tada%'; becomes... SELECT names FROM things WHERE name LIKE 'XXX'; This has proven to be a very interesting and useful tool. You should DL it and try it on your long_queries log file. Whoever runs mysql.com should put a copy on the website. It might just be the greatest thing ever (my program, not the website). For more info, and to get a copy, you can get it at: http://www.retards.org/mysql/index.php I'd like to hear people's thought on it. I'm the only person to test it so far, so it'd be nice to know that it works for other people.

BUG?: Creating a copy of a database with InnoDB tables
I have a database with a mix of myisam and innodb tables. I want to create a copy of this database (ie the database name is different but the table names and structures are the same) on the same server. When I issue the create table command I get the following error: ERROR 1005: Can't create table './new_database_name/same_table_name.frm' (errno: 137) and the table is not created. If I change the type to myisam, with everything else the same, it works fine. Similarly if I use a different table name for the new table it works fine. But if I then try to use alter table to either change the type back to InnoDB or change the name back to match the table name in the original I get the error: ERROR 2013: Lost connection to MySQL server during query and the table remains unaltered. I need InnoDB type tables for transactional support and I want the same database name so my application can refer to either database without having to search and replace all the table names. I can't find anything in the manual about this. Is it impossible to have two InnoDB tables of the same name in different databases on the same server? or is this a bug? I am using Linux kernel 2.2.17-21mdk and MySQL version 3.23.37 on off-the-shelf Intel hardware. Thanks for you help.

mySQL design for the questionnaire
As a student CGI programmer, I've been working on an online questionnaire.
I have been working so hard to design the mysql db part, still I'm not
sure if I've done it right. Still somethings seem to be awkward.
Here I'm DESCRIBing the tables for you, then i'm explaining how I
inteded to use it:
mysql DESC cral2_questions;
+-+---+--+-+-++-+
| Field | Type | Null | Key | Default | Extra
+-+---+--+-+-++-+
| question_id | int(10) unsigned | | PRI | NULL| auto_increment
| question| text | | | |
| type| enum('r','c','t') | | | r |
| calculate | enum('yes','no') | YES | | NULL|
+-+---+--+-+-++-+
4 rows in set (0.01 sec)
mysql DESC cral2_answers;
++--+--+-+-+---+-+
| Field | Type | Null | Key | Default | Extra |
++--+--+-+-+---+-+
| answer_id | int(10) unsigned | | | 0 | |
| question_id| int(10) unsigned | | | 0 | |
| answer | char(200)| | | | |
| if_checked | int(10) unsigned | YES | | NULL| |
| if_not_checked | int(10) unsigned | YES | | NULL| |
++--+--+-+-+---+-+
5 rows in set (0.00 sec)
The first table stores questions and the second one stores their answers.
If you look at the type column, r stands for RADIO BUTTONED, which means
only one of the options could be checked, c means CHECK BOXED or CHECK
ALL THAT APPLY type of questions, and t stands for TEXT FIELDED, and
respondent would have to type something in, which will be matched agains
a respective REGEXP.
CGI script also calculates the results, and provides an instant feedback
depending on the score a student gets. Of course in addition to the above
tables, I'll be needing a table for storing each students information by
assigning an auto_incrementing number for each student, storing the the
students answers, answer key table.
Do you guys think I'm making it too much complicated? I can give you the
link for the initial step of the application. I developed it for the
experts where they rated and provided feedback for each item, according to
which we had to fine-tune the questions. Since we have the fine-tuned
questions now, I started working on the final part (for students).
URL: http://www.ultracgis.com/cgi-bin/cral.v1.cgi
You can access the questionnaire from here. And the control panel is at
http://www.ultracgis.com/cgi-bin/cral.v1.cgi/ControlPanel
I really need experts ideas.
Thank you

databases disappear...
For the first time developing a PHP-MySQL system, I am experiencing strange things. Perhaps it is the off-line mode (Localhost) I am running Apache in, or my Wintel 98SE Pentium3. So I create and populate 3 small tables in a database with a standard little PHP script. Then I start working on my other PHP scripts and testing them out. Of course there are mistakes, like forgotten semicolons or a left bracket where it should be a right one (parse errors), and I correct them, untill I get a nice output on my screen. But suddenly - Offset 0 is not valid for this result set. This is a mysql_data_seek() error, but that is probably a coincidence. The point is: MySQL suddenly thinks that the database is empty, as if it was destroyed. When I look in my MYSQL directory tree, I find my database in the \data subdirectory. So it is present (3 files for each table). When I look at the date stamps for the files, all maintain their creation date/time, although I did make changes to the tables during testing - except one table, with just one row in it (my user/password), did change the timestamp, but I did not access that one (it does not work under Windows)! It get weirder. I must physically delete the database from the MySQL data directory, before I can create them anew, with the same little script I mentioned above. Usually I can access the tabels again then, but quite often, I don't see the newly created tables, but the changed version from a previous test - although I deleted those from my hard disk. So I presume there is a cache somewhere, maintained by Windows, Apache, MySQL or PHP. Can I flush that cache? How can I stop this weird behaviour? I hope I am not really damaging my database, because when I will be working with the real thing later on, I can not afford to have to start from scratch over and over again. Is there a workaround?

Re: Conversion from Access JOIN syntax to MySQL JOIN syntax...
Thanks! I was able to work on the query today, and manually assemble a query that did the same thing. And thus, was a lot faster. The main contention MySQL seems to have is the nested joins, such as when Access does this: FROM (((leg_version_hist RIGHT JOIN (leg_comm_hist RIGHT JOIN leg_activity ON leg_comm_hist.leg_activity_id = leg_activity.id)... For some reason MySQL doesn't like that. :) It's expecting a table name, not another JOIN. At least that what it seems to me, but I could be wrong, not being very experienced with joins. My query in MySQL ended being a lot clean looking, at least to me: SELECT leg_activity.activity_date, leg_transitions.trans_desc, leg_text.leg_version, body_list.body_name FROM leg_activity LEFT JOIN leg_comm_hist ON leg_activity.id = leg_comm_hist.leg_activity_id LEFT JOIN body_list ON leg_comm_hist.body_list_id = body_list.id LEFT JOIN leg_version_hist ON leg_activity.id = leg_version_hist.leg_activity_id LEFT JOIN leg_text ON leg_version_hist.leg_text_id = leg_text.id LEFT JOIN leg_transitions ON leg_activity.transition_id = leg_transitions.id WHERE leg_activity.leg_header_id = 8 And it works very well.
