Re: myODBC?
In my understanding, myODBC is a middleware for programs which don't know how to deal directly with mySQL. So if you use perl or php, you won't ever use ODBC, as this only slows things down, obviously. ODBC is kind of a workaround in my understanding. Please correct me, if I'm wrong.

I don't know exactly what you mean, but if I do, I would write
some functions which do the job. For example, this function
retrieves the address of a client from the client ID:
function getAddr($id){
...
}
In these functions, you are not limited in any way except by your
skills and fantasy.

Re: store and display image with java
Bin Cai schrieb am Donnerstag, 23. August 2001, 23:24:01: > could you tell me how to store image in mysql database and display on web > using java. urgently Do it like any other insert, but care for special characters. In php, you would wrap data with addSlashes() and remove them on retrieval with stripSlashes(). But... you better not insert images into a table. Yes, you can do it, but it is generally considered a bad idea. Read about it at http://www.bitbybit.dk/mysqlfaq/ - if the images have to be provided by users, use the upload functions of your system. php for example has upload support built in. Next you have to care for the appropriate write rights for those files. These can be handled safely without compromising system security. Store all data associated with the pictures in a table except the picture itself, which should be taken care of by the file sytem. rasmus on files in databases: When dealing with images, it is of course possible to insert the image data into the database as binary blobs. However, the value in doing that is questionable. Until databases provide you with cool pattern recognition tools that will let you search a blob for a picture of a rose, having the image data itself in the database isn't of much use. Every operating system comes with a finely tuned blob database. It is called your file system. So, just put the full-path filename into the database and leave the images sitting somewhere on your disk. You will save yourself much aggrevation in the long run. http://conf.php.net/pres/index.php?p=slides%2Fintro&id=or2001 Herzlich Werner -- MySQL in Deutschland: Anpassung, Unterstützung, Schulung für Sie __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Dr. Werner Stürenburg <[EMAIL PROTECTED]> / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Consultant /_/ /_/\_, /___/\___\_\___/ Bielefeld, Germany <___/ www.mysql.com +49-5224-997-407 Fax -409 - 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?

The query looks fine to me. I would investigate if the result is
not correct, i.e. you don't have any record that complies to the
constraint.
But also consider, if you don't want to ask for
select subject,subhead,subsubhead,data2,data3,see_also
from npl_detail
where (subject like '% asia %'
AND NOT subject like '%winter%')
OR
(subhead like '% asia %'
AND NOT subhead like '%winter%')
OR
(subsubhead like '% asia %'
AND NOT subsubhead like '%winter%')
OR
(data2 like '% asia %'
AND NOT data2 like '%winter%')
OR
(data3 like '% asia %'
AND NOT data3 like '%winter%')
OR
(see_also like '% asia %'
AND NOT see_also like '%winter%')

Nobody there to give it a try: I guess this is because programmers are lazy. So they omit quotes if they can. And they can once it is agreed upon what it means.

Re: Mysql Installation

With this you can install MySQL as a service, start the service and monitor MySQL. This will also automaticly shut down MySQL on Win9x when the machine needs to be rebooted. Don't know if this applies to NT as well, but I should think so and you can find out immediately. -- Herzlich Werner MySQL in Deutschland: Anpassung, Unterstützung, Schulung für Sie __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Dr. Werner Stürenburg <[EMAIL PROTECTED]> / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Consultant /_/ /_/\_, /___/\___\_\___/ Bielefeld, Germany <___/ www.mysql.com +49-5224-997-407 Fax -409 - 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?

Excerpt from my Readme: - This version is configured to be installed in c:\mysql. You can however copy this anywhere as long as you don't change the directory structure. For example: mkdir d:\mysql xcopy c:\mysql\*.* d:\mysql mysqld should be able to automaticly find its files based on where mysqld is located. If you want to use files from some other place, you can tell mysqld to use some other directory with --basedir='path'. You can also create a c:\\my.cnf file that holds any default options for the MySQL server. - If you have problems installing mysqld as a service, try starting mysqld with the full path: 'C:\mysql\bin\mysqld --install'. If this doesn't work, you can get mysqld to start properly by fixing the path in the registry! -- Herzlich Werner MySQL in Deutschland: Anpassung, Unterstützung, Schulung für Sie __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Dr. Werner Stürenburg <[EMAIL PROTECTED]> / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Consultant /_/ /_/\_, /___/\___\_\___/ Bielefeld, Germany <___/ www.mysql.com +49-5224-997-407 Fax -409 - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?

I don't have the time to test it, but I would think that LAST_INSERT_ID() should return the last autoincrement value of the last insert, so if you have autoincrement columns to all your tables, you won't get what you want or rather run into big trouble :-( You play safe if you stuff the first number you are interested in into a variable of your program and use this one for all subsequent inserts. -- Herzlich Werner MySQL in Deutschland: Anpassung, Unterstützung, Schulung für Sie __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Dr. Werner Stürenburg <[EMAIL PROTECTED]> / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Consultant /_/ /_/\_, /___/\___\_\___/ Bielefeld, Germany <___/ www.mysql.com +49-5224-997-407 Fax -409 - 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?

ISPs don't have trouble with it as this info doesn't lead somewhere. Users cannot access databases of other users unless set up this way, they only have names. The names usually correspond to the subdirs of those users, and every user can see these as well using telnet or ftp.

Re: case sensitivity issue
> I'm having trouble with what appears to be a case sensitivity issue. > Essentially, when I use the "right" case for a table name, the query fails, > but when I use the wrong case, the query succeeds. Well, it seems to depend on the system you are using. I noticed that when I created tables through phpMyAdmin on my local Win system, that the table(=file) was created on disk lower case only. It doesn't matter on Win, as the file system is not case sensitive, but it does on Linux. So you have to be careful if you transfer tables. I didn't see the create table syntax make any mistakes, so I think it is phpMyAdmin, but I don't know - I didn't care to check. Check the tablename(=filename) and rename the table or change the name in your scripts. -- Herzlich Werner Stürenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - 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?
