Re: LAST_INSERT_ID returning 3 rows?
So sprach Graeme B. Davis am Tue, May 01, 2001 at 01:09:15PM -0400: Ok I was thinking that you had to tell LAST_INSERT_ID the table you wanted to get the last insert id from. What if you run a web site and you have 10 tables in a database, how can you tell what the last insert id of table 6 was? You can't. last_insert_id() will tell you the last_insert_id from the current session/connection.

distinct on varchar fields
Hi All, when I use a distinct on varchar fields, does mySQL truncate the value of the string to some set value. This two queries give me a completely different number of rows and I am not sure how to influence the behaviour: select distinct x from y; (many rows result) and select distinct concat(some long string,x,some more string from y (one row result) where x is a varchar(255) field. Is there any way that I can get the same results with both queries or as an alternative use: select concat(some long string, distinct x,some more string) from y, where the problem is that distinct is not allowed in concat (as in any other function for that matter as I assume) Thanks , Markus - 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?

Occasional hang of mysql
Hi there! I encounterd with a problem recently. Mysql occasionally hangs so that it can't be killed with -SIGKILL, that is there is one thread persist after killall -9 mysqld and it can't be killed in any way. The only way to get mysql back to work is server reboot. I'm using mysql-3.23.37 on RedHat 6.2 linux kernel 2.4.3. It happens both on binary distribution and on myself compiled one.

RTFM - Show locks
database, sql Hi there I have tried looking in the manual but can't see the solution to this. user a issues a lock on table1, userb then tries to do a select and obviously the select will wait until the lock is released. So my questions are :- 1. How do you change the 'timeout' period that userb will wait for? 2. When the timeout is reached, I want to give the user a message box that shows them who is currently locking the table. How do I see who is locking table1?

Re: auto_increment
True. The only thing that could be done is write a UDF (user-defined function), which accepts a table and field name as parameters and somehow manages to find the first unused ID in that table.. and hope it is atomic, too.. I don't think this is too easy to do, though :) G'luck, Peter -- Hey, out there - is it *you* reading me, or is it someone else?

Re: Database size
Hi, I have a problem, my database has reached Linux Redhat 7.1 max file size. (2147483647 Bytes). Does eny one know what i can do to make a lager database. (lager filesystem) Thanks Erik Dhiin I myself run a 300Gb database on a Linux redhat 6.0 Machine. And it works fine. What you do is to read the manual about the CREATE TABLE RAIDTYPE = ... But before you do that you need to recompile using --with-raid, or download the -max version wich I think has the raid option. What the raid option do is to split the data files up into alot of smaller files (RAIDCHUNKS=XX) But only the datafile. Not the indexfile, with is my problem. So What I have done is to create my own indexfiles (its about 170 tables) and agve a realy simple key column (that isn't space comsuming in the index) I loose alot of performance in many of the serahces, but the searching in the indexfiles of my own I Can make a query over the 300Gb (about 4 500 000 000 rows) in about 2 sec, wich is ok for now. /roger - 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 believe that one way to do this would be to create a file with any SQL commands you want to run and then redirect it to mysql via back ticks: `mysql -uroot sql_command_file`; Normally, mysql expects a table listed after -uroot, but it might work if sql_command_file has 'create database db name here' in it. -Brian - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, May 04, 2001 8:34 AM Subject: some question about create db I have to create a database from an application (written in perl) how can I do? how can I create a db if the user is not a root? which command can I use?

Re: some question about create db
That's a good question and I need some help related to the same too. Usually I create scripts like: createSequences.sql, createTableX.sql, createTableY.sql, populateTableX,etc.. that are called by a script called makeDB.sql The way I run it in Oracle is: sqL @makeDB How can I do the same with mySQL???

Newbie installation problems with Apache/MySQL/PHP under Linux
Rather than tell me my question is too far off-topic from MySQL list, would you please suggest another list that you know of? Thanks, but if you are willing to help, here is my problem: I'm attempting to get Apache, MySQL, and PHP working together on a RedHat Linux system that I have total control of. My PHP fasteasy book by Meloni and its associated CD-ROM have been anything but fasteasy. MySQL and Apache installations go beautifully. It's not till I try to rebuild PHP to use MySQL and to work with Apache as a dynamic server object (DSO) that everything falls apart. I've tried numerous distributions/versions, source versus RPMs, and every FAQ suggestion that I can find. Here is my latest error, and one that has surfaced under several variations of installations I've tried: After error-free rebuilds and installations of MySQL, Apache, and PHP, I attempt to restart apache (it worked before rebuilding PHP) using ./sbin/apachectl start command. I get this error message: Syntax error on line 26 of /usr/local/apache_1.3.3/etc/httpd.conf: Cannot load /usr/local/apache_1.3.3/libexec/libphp4.so int server: /usr/local/apache_1.3.3/libexec/libphp4so: undefined symbol: uncompress. ./sbin/apachectl start: httpd could not be started Line 26 just tells location of libphp4.so file. It's where it's supposed to be and seems OK except that it appears to have one (or more?) unresolved symbols. * Do I need to locate a pre-built version of libphp4.so and download it? If so, where might I find that? * Do I need to learn to rebuild libphp4.so from its source? If so, where might I learn to do that? And how come *I* need to do this when (according to PHP book and FAQs) other persons trying the same thing apparently don't have to do it? I know I'm going to love MySQL if I can just get it to start working with Apache and PHP. I would deeply appreciate any help you could offer. Thanks in advance! Kelly D.

help with libmysqlclient.so
Hi, I have recently installed mysql-3.23.29a-gamma on Solaris 2.8. This works fine but I am having problems installing the Msql-Mysql Perl module. This makes but bombs out during testing with what seems to be a fairly common error (I've been scouring email lists)... Can't load '../blib/arch/auto/DBD/mysql/mysql.so'for module DBD::mysql: ld.so.1: ../../perl: fatal: relocation error: file ../blib/arch/auto/DBD/mysql/mysql.so: symbol uncompress: referenced symbol not found at ../../lib/DynaLoader.pm line 206. It seems that the reference to mysql.so in fact means libmysqlclient.so with the solution being to move this file into the library path for shared libraries. My problem is that libmysqlclient.so has not installed. I've checked carefully with find / -name 'libmysqlclient*' but all this finds is the static library libmysqlclient.a. I've tried to build the module using the this static library... perl Makeperl.PL --static --config (perl is 5.6 which seems fine) but it still looks for the shared library. I'm probably doing something totally silly but if not can anyone help? Is it possible to download libmysqlclient.so (I've seen it for Linux - as part of an RPM (?) package - but not for Solaris)? Or is there a patch? Any help will be much appreciated.

Re: database problems
I have a similar problem to this.. What happens is somehow something is causing mysql to hang which forces it to reach max connections.. if i shutdown and restart mysql using safe_mysqld --skip=networking it starts fine.. will do selects fine but not inserts because the tables that were being inserted to while the hang caught have become currupted.. I shutdown mysql, myisamchk -r the tables, it reports the tables were fixed. I then restart mysql and when trying to insert into the fixed table it just hangs forever.. if i do a drop on the table and recreate it it goes back to working fine.. so it seems the myisamchk is not fixing the tables.. any clues? -- Webmaster AngelHaven.com Gerald Clark wrote: Shut down the server before repairing tables.

Peter I've had a chance to several times found data in one of the tables Peter completely destroyed - the data looked like random. mysql select * from g01layers_stat_cities limit 10; Peter ++--++++++ Peter | id | type | begin | counter| last | last_hit | page_group | Peter ++--++++++ Peter | 539167267 | 84 | 20231203141129 | 1920234272 | 20320611141829 | 1713399154 |111 | Peter | 1650553888 | 108 | 20241103100405 | 1684091184 | 20311128204214 | 1936291423 | 39 | Peter | 1124731427 | 82 | 20061110120717 | 577632 | 20241029051540 | 1684091184 |118 | Peter | 1985967218 | 105 | 19750527085147 | 1684611104 | 20311125200848 | 691024168 | 32 | Peter | 1734964078 | 110 | 20110715200141 | 1310741583 | 19870304184629 | 1869903201 | 95 | Peter | 1701995374 | 109 | 19930820102541 | 1663049738 | 20311125210119 | 1767862885 |100 | Peter | 678719081 | 49 | 20320408165928 | 1734964078 | 19870323012758 | 1095124292 | 85 | Peter | 807870548 | 39 | 20141028110448 | 1280658976 | 19870113150012 | 544437280 |116 | Peter | 1953719661 | 97 | 19960219154325 | 170666292 | 20340728025216 | 1948280176 |105 | Peter | 1953393017 | 40 | 20320408165931 | 1734964078 | 19870323012758 | 1095124292 | 85 | Peter ++--++++++ Peter 10 rows in set (0.00 sec) Peter It did't look like a possible bug in mysql so I checked other thing. I Peter took a table and completely replaced the data file with over file Peter which is not connected with mysql in any way, really it was a Peter mysqldump output for one of the databases and mysql was easily Peter able to repair the same way as it repairs a bit damaged tables - some Peter of duplicate key records there removed but it looked quite normal. Peter Of couse I had a trash in a file afterwards. Peter I don't have good solution for this yet, but it's not quite nice Peter behavior :) In a fixed format file, all rows are stored after each other; No row markers, no checksums... This is very fast an efficient and pretty secure. The bad thing with this is that if you somehow get bad data in the table, then MySQL has no way of knowing if the data is a correct row or not.

Question
Hello all, mysql uses only one index for the entire execution of a query? i.e. if it uses one index to do the row retrieval because it matches the where criteria but then has to sort these rows on something else that would benefit from index, would mysql use this index? tia, thalis - 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?
