Re: MySQL secure access
If I am your customer and the data related to my web contents and/or
services stored(this is more than likely if the hosting service is used)
in the database at your site, I would definitely claim that the access to
data will be appropriate. Ex, You have Web services using a hosting
service. And the Web services collect the customers' info. Shouldn't
you need to access the database which stored all your customers' info.
In addition, it's a trust-based relationship. But the hosting service should
not have access to the customers' data even though the customers'
databases reside at the hosting site. That's more appropriate in the
business process and prevent the possible legal matter. Because the
customers can simply claim that It's my data and not yours!
The right practice will be to seperate your company's database and
customer's databases on different hosts. And your company can provide
the proper access to your customers to their databases. Otherwise, they
will move on to somewhere else who can do for their needs.

Hi, all,
I am now using MySQL with MySQL Front, where i knew that it can access
ALL
the databases that store remotely.
My company is doing hosting services. And we are using MySQL as
our database system. Currently, we have our own databases + customer's
databases
store in our hosting server. But our customer requested to have their
own access on their databases, which i don't want them to see those
databases
that not belongs to them. Can i do that ?
Thanx in advance for anyhelp.
regards,
alice

Need help to connect MySQL which is on Linux thru win32 PC
Keys: sql, query Hi Steve, I got your email from the MYSQL list, and I undertood that you have some experience about using Mysql tables in an application developed by Delphi. I am just at the begining of the way. Still I am dying to get any response or see the already existing defined tables of the MySQL which is running on a Linux server. For testing I installed the MYSQL win32 version both on the same PC and into another PC whicha are on the same local NET. I can reach both the local databases, and the win32 MySql server (on the PC2) with the same programs, but still I did'n see the databases of the MySQL which is on the Linux Server. Do you have anything to advise me to solve this problem? Sincerely.

DBI: error 12 from table handler , Can't allocate memory, temp tables, WHY?
Hi. I have a perl script that uses many temporary tables (HEAP mostly) and when running the script many times in parallel some of the script instances fail. The query uses temporary tables and recently I discovered that some of the queries uses filesort (disk access) due to GROUP BY making the response time for every concurrent script longer than expected. Here is the error I get: DBD::mysql::db do failed: Got error 12 from table handler at /home/travis/tr.pl ... Looking at the log files for MySQL I cant figure out what queries cause the failure but generally speaking I assume that the problem is the temporary tables. Looking up the error code received by DBI/DBD I get: 'perror 12' Error code 12: Cannot allocate memory Can't allocate memory? Why is that? Below is my server info and my default my-huge.cnf settings. I have tried to set the SET SQL_BIG_RESULT=1 resulting in all temp tables getting written to disk, but the error still exists. I have tried to modify the parameters in my.cnf, primarily adjusting key_buffer and sort_buffer, but the default my-huge.cnf configuration seems to work the best.

Bug Report: Replication in 4.0.5beta
The environment info was copied from the mysqlbug command by our external hosting company who truncated the lines therefore the last couple of characters from each line is not there however it was a Solaris 2.8 binary download of 4.0.5beta so you would have all of the info anyway. Description: I am using MySQL 4.0.5beta on Solaris 2.8 from a binary version downloaded from www.mysql.com on the 19th of November 2002. I have one database set up as the master database and 2 databases set up as slave databases. Each database is on a separate SUN server. I am performing intense load testing on MySQL replicated databases using InnoDB tables and transactions and I have come across what is most likely a bug. The replication is failing on the slaves with the following error (this appears both slaves error logs at the same time) :- 021127 13:48:28 Error in Log_event::read_log_event(): 'Event too big', data_len=1397639424,event_type=111 021127 13:55:36 Error in Log_event::read_log_event(): 'Event too big', data_len=1397639424,event_type=111 As you can see the data_len is 1.3G. The master log position at this time was less than 300Meg so a single event, even if I did about 500,000 inserts in a transaction block, could not be larger than 300Meg. I have MAX_BINLOG_SIZE set to 2Meg on the master database and the slaves. As it is I know that the transactions were small as the records were being inserted on the slave machines which only happens after the commit takes place on the master. I have run this test several times and it falls over after a different number of records have been replicated each time (I performed reset master and reset slave on the databases between tests to ensure a clean run) but the reported error is the same i.e. data_len being 1.3G. I feel the master log file switching has somehow corrupted the binary log file. I had previously loaded 1,000,000 records on this replicated server and it worked fine. However the binary log files were never switched because the server was under too much load. I then changed my method of allocating sequential keys which slowed things down enough for the log switching to occur at the size specified in MAX_BINLOG_SIZE and I got the error. How-To-Repeat: Re-run the test after performing a reset master and reset slave on the appropriate databases. Fix: If I take out the setting of MAX_BINLOG_SIZE to let it use the default size of 1Gig and re-run my test it works OK.

replication and if not exists temporary tables
Description: A website we recently built contains a highscore table. People play a game, and can then submit their name and score to the table. When viewing the table, I then need to rank the scores using an order by... However since I want to be able to only select arbitrary intervals in the ranks (I want to ask the question show me position 200-300), I figured I needed to use a temporary table. All my tables are innodb tables. I'm doing this in Java using the mm.mysql-2.0.14 driver. I'm using MySQL 3.23.53. The SQL I then got is: 1. create temporary table if not exists Highscores_result ( position int, name varchar(255), country varchar(255), score int ) type=innodb; 2. delete from Highscores_result; 3. set @n=0; 4. insert into Highscores_result select @n:=@n+1 as rownum, name, country, score from Highscores order by score desc; I grab a connection, set autocommit to false, create a statement (not prepared) and then do stmt.addBatch() for each of the statements, execute, and then commit(). And then I can read out say position 200-300 from the temporary table. The MySQL instance that runs this have got two replication slaves. One which is constantly connected, and one which connects every night for nightly backups. The one which is constantly connected works fine and keeps replicating. However the one connecting every night always stops the slave thread with a: ERROR: 1146 Table 'foo.Highscores_result' doesn't exist 021127 20:00:03 Slave: error running query 'delete from Highscores_result' 021127 20:00:03 Error running query, slave aborted. Fix the problem, and re-start the slave thread with mysqladmin start-slave. We stopped at log 'master-bin.018' position 566235 021127 20:00:03 Slave thread exiting, replication stopped in log 'master-bin.018' at position 566235 Hypothesis: Could this be down to that temporary tables are connection unique and I'm killing my connection every now and then, and that the slave does not actually create a table on create table if not exists if the master didn't create it. E.g. master log looks something like: - CREATE TABLE IF NOT EXISTS (Creates table on master since it doesn't exist) - DELETE FROM - SET - INSERT -- I disconnect my slave -- I reconnect my slave - CREATE TABLE IF NOT EXISTS (Doesn' create on slave since it existed on the master) - DELETE FROM - SET - INSERT How-To-Repeat: Set up a replication slave that disconnects and reconnects using cron. Run the above kind of SQL. Fix: If the hypothesis is correct, perhaps the slave must honor create table if not exists regardless if this was a success on the master or not.

Application level security
Hi All, I'm writing a application that needs row level security in it so that only certain users can view/change etc. certain records. I know that MySQL currently does not have row level security, and when I've asked this list before I've been given some helpfull suggestions (although none of them would actually work for me). So I've decided that the only way to go is to put the security logic into the application I am building. This works fine for my application, but means that if anyone connects directly to the server using the MySQL client etc, then they'll be able to see/update everything - making it a pretty weak security system. I've had two thoughts about this, but am willing to hear of any other thoughts people might have. One that I could do right now is to get my program to add something to the password of every user (users are created using the program and passwords can be changed using it too). This way if they try to connect to the server directly they won't have the extra bit on their passwords and it won't let them connect. The program could take care of adding this extra bit each time anything password related was needed so it shouldn't be a problem in this respect, however if anyone discovered the extra bit then it would be imposible to change the extra bit without giving everyone new passwords (which would be a real pain). A second way would be if there was like an application password in the security area that could be set and would be needed for connection - sort of like the ssl extra stuff that's been added recently. The downside of this is it isn't currently there and I'd need to convince someone at MySQL that it was worth adding and then wait for it to be added, the upside is that it would be easier to change if the application password was discovered. I've looked a little at the ssl/encryption stuff to see if I could use that but I don't think it can really help me achieve what I'm trying to achieve but if someone thinks it can I'd love to hear how. If anyone has any other ideas, can see problems that I haven't seen in the above ideas then I'd appreciate knowing. Are there any others having this problem (or is it just me!)?

Re: Recovery with binary logs.
Hi Manuel, On Tue, 2002-11-26 at 21:38, Manuel Villasante wrote: Hi, I have a few questions regarding recovery of a database using binary logs. 1) If you have a set of binary logs in your directory mylog-bin.001 to mylog-bin.nmp, is there an easy way to find out which logs you need to run since the last backup? In other words, when according to the instructions, after replacing the database files with the backup ones, you run the command: mysqlbinlog mylog-bin.[0-9]* | mysql does it know automatically which set to include so as to not incorporate logs that are too old? Or do we have to manually perform a selection? If so, is there a way to figure out easily the subset if one has not been watching it? At the time of backup, you need to record the master position of the server you are backing up - or perform reset master, but this might threaten your recovery if you have a failure during the current backup process and have to roll-forward from your previous dump (requiring the binary logs that reset master have just deleted). If you record the master position (file name, offset) during your dump, you need to ensure all tables involved in the dump are locked. mysqlhotcopy can do all this for you, see the --record_log_pos option. Unfortunately, mysqlhotcopy only works on Unix-like OSes, and so you will need to roll your own if your OS is not supported. 2) If a loss of data has been caused by an unwanted statement like DROP DATABASE... or DROP TABLE VeryImportantOne, how can one delete that statement from the bin-log before using it for recovery and repeat the mistake? You could write the output of mysqlbinlog to file, edit the file, and then pipe the file into the mysql monitor: mysqlbinlog mylog-bin.[0-9]* file.sql edit file.sql mysql file.sql good luck, Martin - 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: Application level security
Noel, I'm sorry if this is obvious, but have you considered putting a firewall in the way? If your application is on the same machine as the database, block all connections except to the port your application runs on (ie probably 80 if it's a web application)? The firewall will block connections from any machine to the database, and only local connections can be made to it. If your database is on another machine, protect the database server with the firewall so that only your application server can connect to the mysql server (or configure it so only certain other trusted hosts can too).

Hi, doeas anyone know if it's possible to add 2 or more numeric values together that are in the same cell in Mysql: IE: i have a cloumn called price that for any entry may contain more than one value, lets say £1.00 and £2.00 Is there a way that i can get these values added together ? I know it's easy if they are in separate rows but unfortunately they're not. see the example iditemprice 1 apple 1.00 2 apple 1.00 pear2.00 3 banana 1.00 I need to get the sum for price for id 2.

It looks like your 'id' column is not unique, but is used to group several rows (apples and pears) together. In that case, you can use: SELECT id, SUM(price) FROM mytable WHERE id = 2 GROUP BY id; Regards, Fred. -- Fred van Engen XB Networks B.V. email: [EMAIL PROTECTED]Televisieweg 2 tel: +31 36 5462400 1322 AC Almere fax: +31 36 5462424 The Netherlands - 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: adding values together
You appear to be violating the repeating value rules of relational database. Multivalue databases (Pick and Pick like) support this concept but they are rather uncommon now. You probably need to create a related table. Actually, you might want to do a little study on the general idea of relational databases. Not meaning to be negative here because nobody is born with the knowledge.

LOAD DATA LOCAL INFILE
Hello all --- I posted this yesterday, perhaps before my subscription took effect, and so I am not sure that it got distributed. So, forgive the repetition in sending, if that's the case. Anyway . . . Here's the question, as succinctly as I can formulate it: The documentation seems to say that one can load a tab-delimited text file located in the current directory of the client host into a database by running the client mysql and executing the following command: mysql LOAD DATA LOCAL INFILE absence.txt into table absence; When absence.txt is located in /Users/jack/Desktop/SQL_stuff/samp_db/, then the command: mysql LOAD DATA LOCAL INFILE /Users/jack/Desktop/SQL_stuff/samp_db/ absence.txt into table absence; does work. But the command: mysql LOAD DATA LOCAL INFILE absence.txt into table absence; does not work. Rather, it produces the error: ERROR: File 'absence.txt' not found (Errcode: 2) That is, absolute pathnames work, but relative pathnames do not. I have been careful to be sure that, when invoking the mysql client, I am in the correct directory, and that when I invoke mysql, that I include the --local-infile option, as the following printout shows: [Jacks-G4:~/Desktop/SQL_stuff/samp_db] jack% mysql --local-infile samp_db Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Welcome to the MySQL monitor.

[Fwd: possible problems with FLUSH TABLES WITH READ LOCK]
Sorry to insist, but nobody has any clues about this ? I can supply further info if needed. Is the FLUSH TABLES WITH READ LOCK functionality well tested ? Having corrupted backups is annoying, and I can't really take the system down for a 4-hour tape backup... ;( Message original Sujet: possible problems with FLUSH TABLES WITH READ LOCK De: Antoine [EMAIL PROTECTED] Date: Mar, 26 Novembre 2002, 17:27 A: [EMAIL PROTECTED] Hi, I am using FLUSH TABLES WITH READ LOCK to get consistent snapshots of my database without shutting it down. The setup is : - bi-P4 Xeon with Redhat 7.3 - 2.4.19 kernel with properly patched LVM (compiled from source) - MySQL server 4.0.4 (compiled from source) - ext3 filesystem on a 44 GB LVM logical volume named /dev/vgdata/data - the whole database is 20 GB in size - all tables are MYISAM ; some with dynamic records, some fixed, some compressed - some tables - not all - are created with DELAYED_KEY_WRITE=1 to get more speed (30% faster thanks to this) The backup sequence is : - FLUSH TABLES WITH READ LOCK - lvcreate -L 5G -c 256k -s -n backup /dev/vgdata/data (this creates a 5GB snapshot volume named backup from the logical volume containing the database) - UNLOCK TABLES - mount /dev/vgdata/backup /backup -oro,noatime - cd /backup/ ; tar cvf /dev/st0 * Today I've tried restoring a backup on a test partition just to see (you're never too careful). Restoring is OK (of course) but when I run myisamchk -c *.MYI, just to be sure, I get various kinds of errors, on some tables but not all. Common errors include : 1 clients is using or hasn't closed the table properly error: Size of indexfile is: 17404928Should be: 17507328 warning: Size of datafile is: 24922872Should be: 24896378 error: Found 185731 keys of 186676 error: Found key at page 1024 that points to record outside datafile In fact, all kind of errors that you'd expect to find if you copy your files without doing a FLUSH TABLES WITH READ LOCK first. Thus I was wondering if the latter command does work properly. Is it likeky to be due to : - SMP problems ? (it has hyperthreading enabled, BTW, but this shouldn't make any further difference : it just sees 4 logical CPUs instead of 2) - DELAYED_KEY_WRITE ? (but some tables that aren't created as such have problems too, so this shouldn't be the _only_ problem) - specific Linux locking behaviour wrt flushing locking tables ? - Linux LVM bug ? (unlikely in my opinion, it seems heavily used) - other... ? Please note : tables are written to in a continuous way, so it's no surprise many tables get corrupted if the lock is not absolutely consistent and fail-proof ;)) Also, I know the backup volume is large enough (I print the occupied size at the end of the backup procedure). Well, of course, it may just be the backup tape itself that was screwed up, but it doesn't seem very likely, at least in my opinion, otherwise un-tar-ing it should have failed somewhere. What do you think ?

E.g. master log looks something like: patdc - CREATE TABLE IF NOT EXISTS (Creates table on master since it doesn't patdc exist) patdc - DELETE FROM patdc - SET patdc - INSERT patdc -- I disconnect my slave patdc -- I reconnect my slave patdc - CREATE TABLE IF NOT EXISTS (Doesn' create on slave since it existed on the master) patdc - DELETE FROM patdc - SET patdc - INSERT How-To-Repeat: patdc Set up a replication slave that disconnects and reconnects using cron.

Several changes were made in 4.0.2 and after that you should consider. New privileges were added in 4.0.2, but a couple of these weren't added to the db table until 4.0.4, so you should *avoid* using 4.0.2 or 4.0.3. Also, some operations now are handled by different privileges. For example, KILL now requires SUPER rather than PROCESS. If you create new users and give them SUPER, reverting may require shifting SUPER back to PROCESS.

Err, no. MySQL prevents that looping as long as each server has a unique server-id. It's very slick, updates on either server get propagated to the other server. I have not stress tested it yet, and my (simple) application only does updates to a single server at a time. The only problem is the auto_increment columns in the tables. Updates that occur on both machines at the same time, that generate the same auto_increment value, causes the slave threads to die: and rightly so. I can, of course, program my application to generate non-conflicting, server independant key values without the need for the auto_increment, but has anyone had any experience with this? Is this really the only impediment to doing full two-way replication? That's the big limitation, yes. -- Jeremy D. Zawodny | Perl, Web, MySQL, Linux Magazine, Yahoo!

Re: Application level security
I've done a similar work in 1997 for one of my clients. The password method will be just part of the security system. But you may want to consider to implement the RBAC in the database. In that way, the users whether they are applications, e.g., business objects, DB interactive tool by human user, or so, will only access to the subset of database based on thier privileges by using ACLs which are also based on the defined security policy in the database. In addition, you may want to use the Asymmetric encryption for some data that needs to be considered a higher security. Pae Hi All, I'm writing a application that needs row level security in it so that only certain users can view/change etc. certain records. I know that MySQL currently does not have row level security, and when I've asked this list before I've been given some helpfull suggestions (although none of them would actually work for me). So I've decided that the only way to go is to put the security logic into the application I am building. This works fine for my application, but means that if anyone connects directly to the server using the MySQL client etc, then they'll be able to see/update everything - making it a pretty weak security system. I've had two thoughts about this, but am willing to hear of any other thoughts people might have. One that I could do right now is to get my program to add something to the password of every user (users are created using the program and passwords can be changed using it too). This way if they try to connect to the server directly they won't have the extra bit on their passwords and it won't let them connect. The program could take care of adding this extra bit each time anything password related was needed so it shouldn't be a problem in this respect, however if anyone discovered the extra bit then it would be imposible to change the extra bit without giving everyone new passwords (which would be a real pain). A second way would be if there was like an application password in the security area that could be set and would be needed for connection - sort of like the ssl extra stuff that's been added recently. The downside of this is it isn't currently there and I'd need to convince someone at MySQL that it was worth adding and then wait for it to be added, the upside is that it would be easier to change if the application password was discovered. I've looked a little at the ssl/encryption stuff to see if I could use that but I don't think it can really help me achieve what I'm trying to achieve but if someone thinks it can I'd love to hear how. If anyone has any other ideas, can see problems that I haven't seen in the above ideas then I'd appreciate knowing. Are there any others having this problem (or is it just me!)?

LOAD DATA LOCAL INFILE
Victoria and Michael: Thanks very much. Following on your suggestions, I then went ahead and put the text file into my directory: /usr/local/mysql so that the file was then /usr/local/mysql/absence.txt and, with that done, the LOAD DATA LOCAL INFILE absence.txt into table absence; command in the mysql client successfully did load it. (It didn't work when put into the /usr/local/mysql/scripts directory or in the /usr/local/mysql/data directory.) Is there anyway to change the place where the client looks when given the relative pathname of a file to be LOADed, or is one stuck with having to put all text files in that one immutable location? (On the Mac, we aren't allowed to see the contents of /usr/local/mysql/ in the GUI. We have to access it through the UNIX Terminal program, and then fiddle with permissions, which, I am not bashful to say, I am reluctant to start doing without comprehending the implications, which, I also am not bashful to say, I don't.)

Users and Databases
Hi everyone, Please pardon my extreme case of the NEWBs on this but I need some help please. Ok I just purchased a book to hopefully clear things up for me, but to no avail. So this is my dilemma: I want to know about MySQL administration, specifically the user management portion of the admining. I want to be able to allow users to create whatever DBs they need. One DB for my Multi-media collection, one for an address book, one DB for links for a web site. Whatever the case may be! But it seems like I can't give a user the option to create and/or delete any DBs that only user X made. So I the admin would have to create each DB and assign appropriate privileges to appropriate users? So to sum up my situation into a question: Is it possible for me to give a user the ability to create and/or delete only their DBs? Or do I have to make the DB for them and then Grant appropriate privileges for that user to that DB? Thanx in advance for the help __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

It is now available in source and binary form for a number of platforms from our download pages at http://www.mysql.com/downloads/ and mirror sites. This is a new beta development release, adding new features and fixing recently discovered bugs. This will be the last release labelled as beta - the upcoming MySQL 4.0.6 will be labelled gamma, which emphasizes the fact that the MySQL 4.0 code base has further stabilized and is becoming ready for productive use. To avoid confusion between the product names of the GPL and non-GPL (commercial) binaries, MySQL AB has now further refined the new naming scheme. Starting with MySQL 4.0.5 and onwards, the following binaries will be available: MySQL Standard (GPL) This is the recommended binary for most users that want to use MySQL under the terms of the GNU General Public License (GPL). It includes the InnoDB Storage Engine and all default features that are considered stable and useful enough for general usage. MySQL Max (GPL) This is an enhanced version of the Standard GPL package. In addition to the InnoDB Storage Engine, it includes additional features like the Berkeley DB (BDB) Storage Engine (certain platforms only) as well as other additional features that are either not exhaustively tested yet or not required for most users, e.g. OpenSSL (where available), User defined functions (UDFs), or BIG_TABLE support. When these features have matured and proven to be stable enough, they will be part of future versions of the Standard binaries. Please note, that not all of these features are included in all binaries. MySQL Classic (Commercial License) Similar to MySQL Standard, but *without* InnoDB and only available as a commercial licensed version. MySQL Pro (Commercial License) Similar to MySQL Standard (*including* InnoDB), but only available as a commercial licensed version. - From the 4.0.5 ChangeLog: Functionality added or changed: * Changed handling of last argument in `WEEK()' so that one can get week number according to the ISO 8601 specification. (Old code should still work). * Fixed that `INSERT DELAY' threads doesn't hang on `Waiting for INSERT' when one sends a `SIGHUP' to `mysqld'. * Change that `AND' works according to SQL ANSI99 when it comes to `NULL' handling. In practice, this only affects queries where you do something like `WHERE ... NOT (NULL AND 0)'. * `mysqld' will now resolve `basedir' to its full path (with `realpath()'). This enables one to use relative symlinks to the MySQL installation directory. This will however cause `show variables' to report different directories on systems where there is a symbolic link in the path. * Fixed that MySQL will not use an index scan on an index that has been disabled with `IGNORE INDEX' or `USE INDEX'. * Added `--use-frm' option to `mysqlcheck'. When used with `REPAIR', it gets the table structure from the `.frm' file, so the table can be repaired even if the `.MYI' header is corrupted. * Fixed bug in `MAX()' optimization when used with `JOIN' and `ON' expressions. * Added support for reading of MySQL 4.1 table definition files. * `BETWEEN' behaviour changed (*note Comparison Operators::). Now `datetime_col BETWEEN timestamp AND timespamp' should work as expected. * One can create `TEMPORARY' `MERGE' tables now. * `DELETE FROM myisam_table' now shrinks not only the `.MYD' file but also the `.MYI' file. * When one uses the `--open-files-limit=#' option to `mysqld_safe' it's now passed on to `mysqld'. * Changed output from `EXPLAIN' from `'where used'' to `'Using where'' to make it more in line with other output. * Removed variable `safe_show_database' as it was not used anymore. * Updated source tree to be built using `automake 1.5' and `libtool 1.4'. * Fixed an inadvertently changed option (`--ignore-space') back to the original `--ignore-spaces' in `mysqlclient'. (Both syntaxes will work). * Don't require `UPDATE' privilege when using `REPLACE'. * Allow braces in joins in all positions. Formerly,

Hi It means you are refering to/using a result id that does not exist. Maybe the query changed or the database is down? Try echoing the query and the error echo mysql_error ( [resource link_identifier]) if not could you send more details to give us a little more to go on Peter --- Excellence in internet and open source software --- Sunmaia Birmingham UK www.sunmaia.net tel. 0121-242-1473 International +44-121-242-1473 --- -Original Message- From: mark horn [mailto:[EMAIL PROTECTED]] Sent: 28 November 2002 22:41 To: [EMAIL PROTECTED] Subject: Warning: Supplied argument is not a valid MySQL result resource Hi I wonder if anyone can help or point me in the right direction for this problem.

Any help? SUM of type TIME in Query?
Have MySQL db with hundreds of thousands of event records from geographically dispersed logging devices. The logs are batched and auto loaded/parsed into MySQL on a daily/weekly basis depending on external factors. As an example, during a 7 period, one device provided 128,000 discrete events of 220 Types. The columns of primary interest are shown here. Col4 is generated by the logging devices as a duration/elapsed time in HH:MM:SS format and is the column of interest in this problem. An abbreviated table of the columns (ordered and numbered for example only) and records looks like; Col1(Char), Col2 (DATE),Col4(TIME) EventType1, -MM-DD HH:MM:SS, 09:53:05 EventType1, -MM-DD HH:MM:SS, 05:56:39 EventType1, -MM-DD HH:MM:SS, 05:53:36 EventType1, -MM-DD HH:MM:SS, 01:11:09 EventType1, -MM-DD HH:MM:SS, 22:48:12 EventType2, -MM-DD HH:MM:SS, 01:11:32 EventType2, -MM-DD HH:MM:SS, 22:48:46 ... etc. n+1 The shell query is: select cols, count(xy), (sum(col4)) as t_dura from db where xyz group by Col1 order by col1 The results using the above as an example would be: Col1 Char, xy, t_dura EventType1, 5, 442201 EventType2, 2, 235978 ... ... n+1 Can anyone provide insight into the SQL syntax to perform the sum and return the results as HH:MM:SS?

Subject: Re: MySQL secure access
If I am your customer and the data related to my web contents and/or
services stored(this is more than likely if the hosting service is used)
in the database at your site, I would definitely claim that the access to
data will be appropriate. Ex, You have Web services using a hosting
service. And the Web services collect the customers' info. Shouldn't
you need to access the database which stored all your customers' info.
In addition, it's a trust-based relationship. But the hosting service
should
not have access to the customers' data even though the customers'
databases reside at the hosting site. That's more appropriate in the
business process and prevent the possible legal matter. Because the
customers can simply claim that It's my data and not yours!
The right practice will be to seperate your company's database and
customer's databases on different hosts. And your company can provide
the proper access to your customers to their databases. Otherwise, they
will move on to somewhere else who can do for their needs.

Hi, all,
I am now using MySQL with MySQL Front, where i knew that it can
access
ALL
the databases that store remotely.
My company is doing hosting services. And we are using MySQL as
our database system. Currently, we have our own databases + customer's
databases
store in our hosting server. But our customer requested to have their
own access on their databases, which i don't want them to see those
databases
that not belongs to them. Can i do that ?
Thanx in advance for anyhelp.
regards,
alice

Error compiling a program using mysql++
Hi
I'm programming using FLTK Toolkit, mysql 3.23.52 (from source code ) and
mysql++ 1.7.9. On win32, i'm using Visual Studio 6.0 and c++ on GNU/Linux.
On win32, it's ok, but on GNU/Linux Debian, has these errors. But who can I
correct it ?
The source academia.cpp compiles ok, but atletas.cpp don't.

FULLTEXT search against a query result
Okay, here we go ...
I would like to do a FULLTEXT search against a query result. There are
multiple columns that have a FULLTEXT index. Hopefully I break this
down in a manner that can be understood.
The fields of interest:
Table events:
event_id [int(11)]
event [varchar(255)]
description [text]
FULLTEXT (event, description)
Table event_times:
event_id [int(11)] from events.event_id
start_date [date]
place [varchar(255)]
FULLTEXT (place)
I would like to search the fields events.event, events.description, and
event_times.place. So hypothetically it would look something like
MATCH(events.event, events.description, event_times.place)
AGAINST('keywords').
The results I need to use for the search is produced from the query:
SELECT events.category_id, events.event_id, events.event,
events.description, event_times.start_date, chc_event_times.place
FROM events INNER JOIN event_times ON events.event_id =
event_times.event_id
GROUP BY events.event_id
If this makes no sense to you or if you need more information, please
let me know.
Thanks for your time.
