MySQL, MyODBC and MS Access
Hello! You are my last chance, reading FAQs and asking in newsgroups gives no effect. I have a problem when connecting a MySQL table in MS Access (2000) through MyODBC. MySQL is ver. 3.23.44 running on FreeBSD 4.5 box. Description of the problem: I connect the table and Access correctly retrieves data. But when user tries to add data or to change any field, access performs an error box that some another user has changed this field when you were changing it, but actually nobody was connected to MySQL at that time. This problem takes place only in Windows'98. When I perform the same operation from Windows XP all is correct. Maybe I have to make some additional settings for MyODBC (version 2.50.39-win95) in Windows98? Please help. Thanks in advance! -- Alexandre Iakovlev System administrator of R D work group Lumex ltd.

How to speed up mods to large table?
Hi! Nick == Nick Arnett [EMAIL PROTECTED] writes: Nick I haven't been able to dig up any specific information about how to get Nick maximum performance when making changes to large tables.

Dropping a column or an index seems Nick exceedingly slow and I'm wondering what parameters matter for this. I'm Nick already using the highest-performance drive I can lay my hands on. What Nick else matters? MySQL currently almost always recreates the full index and data tables when you do an alter table (to be fixed in 4.1).

I've tried mysqld-max-nt and mysqld-max, but have_bdb and have_innodb variables were 'NO'. I use version 3.23.49. Thanks!

Thanks for all your help Mick Paul DuBois wrote: At 13:34 +0100 4/19/02, Mick Watson wrote: Thank you :-) I do realise the SQL is not being used as it should be, but as it is not my database and nor is it my SQL, there's not much I can do to really change either of these I merely have to work with a database that has been produced by a third party group, and I must say at this point that I have nothing but praise for the ensembl group for the difficult job that they have done very well (see http://www.ensembl.org) So, I realise this is not the problem of mySQL, but what I want to try and find out is really the internal workings of mySQL when it performs this operation so that I can understand why my copy of ensembl, which is produced from direct dumps of the main ensembl, behaves differently to the main ensembl. I guess you won't want to hear this, but that is completely the wrong approach. You *might* be able to achieve the same query output on both machines by dumping the database on one machine, then dropping and reloading the tables on both machines using the same copy of the dump. Then presumably both tables will have both records loaded in the same order, and the query *might* produce the same result on both machines. - ...until the table gets modified - ...until MySQL is upgraded on one machine and not the other, and something happens in the query optimizer that changes the query output - ...etc. The group you're working with *must* change the queries to be correct. Otherwise, you're entirely at the mercy of any number of external factors that can change the output and over which you have no control. I guess from what you are saying, that the data is stored randomly, that there is very little I can do to actually make my database behave the same as the main database? Could it be affected in any way by operating system and/or file system? Superficially the data is organised in exactly the same way in both databases, but I have no doubt that things like memory locations are completely different, but possibly if I could understand what the variables are that affect this behaviour I could minimise the inconsistancy...? Thanks for your time Mick Richard Emery wrote: mysql is acting correctly. GROUP BY is used to consolidate data for SUMming, COUNTing, etc. Your SELECT statement makes not such request. You have simply requested the value of a specific field. Data are stored in mysql databases randomly. Therefore, when you request a field's data, you are getting whatever is first in the list of records matching your WHERE clause. Bottom line: you are NOT using GROUP BY as it is supposed to be used.

New Setup

I have had it there for a while, but haven't really done much with getting my head round it. 2. I have figured out some shell commands, and have been able to set a root password. 3. I have also been able to use phpMyAdmin - which I had to modify to take into account the root password etc that is now in place. 4. I can create a database table using the phpMyAdmin forms - and it was relatively easy. However, when I go back to try and set up a new user who has permission to do a range of things on this database, (using shell now), I am given an error ERROR 1044: Access denied for user: 'root@localhost' to database 'cbaa' Shell command I am using mysql GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP - ON cbaa.* - TO cbaa@localhost - IDENTIFIED BY 'itsmeolord'; This seems strange to me, as I figured that root would have permission to do anything (even if it were 'inappropriate'.

If you do not specify innodb_data_home_dir, then the default is that InnoDB creates its data files to the datadir of MySQL. Then you cannot use absolute file paths in innodb_data_file_path. When you the first time create an InnoDB database, it is best that you start the MySQL server from the command prompt. Then InnoDB will print the information about the database creation to the screen, and you see what is happening. See below in section 3 what the printout should look like. For example, in Windows you can start mysqld-max.exe with: your-path-to-mysqldmysqld-max --standalone --console Where to put my.cnf or my.ini in Windows? The rules for Windows are the following: Only one of my.cnf or my.ini should be created. The my.cnf file should be placed in the root directory of the drive C:. The my.ini file should be placed in the WINDIR directory, e.g, C:\WINDOWS or C:\WINNT. You can use the SET command of MS-DOS to print the value of WINDIR. If your PC uses a boot loader where the C: drive is not the boot drive, then your only option is to use the my.ini file. Thanks!

InnoDB and Fulltext Search
Hi, Quote from mysql online documentations: As of Version 4.0.1, MySQL can also perform boolean full-text searches using the IN BOOLEAN MODE modifierA boolean full-text search can also work even without a FULLTEXT index, although it would be slow. I know that InnoDB does not support FULLTEXT INDEXING but can i perform a fulltext search on an InnoDB table? I tried but it doesn't seem to work. The 'match... against()' returns a value of '-1'. Any idea? Thanx. ahk __ Do You Yahoo!? Yahoo! Messenger - Instant Messaging, Instant Gratification.

Re: checksum errors
Resent, because of attachment problem. At 09:52 17-4-2002, Michael Widenius shared with all of us: Melvyn Hi Monty / list, Melvyn I still didn't change anything with the software, and now other tables, Melvyn also with FT indexes are crashing - these tables have never had any Melvyn problems at AIX. Also - the replica (2 servers are in replication with Melvyn eachother) doesn't expose this error. Hardware, OS etc. is exactly the Melvyn same. Built from a make clean make, on the exact same source tree. I'm Melvyn totally baffeled. First, this email list is dedicated for repeatable bug reports. In the future, please use [EMAIL PROTECTED] instead of this list when you have general problems with MySQL. For me - it IS repeatable, just don't know how - exactly, but found a clue: 020416 18:27:25 Error reading packet from server: Lost connection to MySQL server during query (read_errno 0,server_errno=2013) 020416 18:27:25 Slave: Failed reading log event, reconnecting to retry, log 'rep_log.003' position 186510180 020416 18:27:25 Slave: reconnected to master '[EMAIL PROTECTED]:3306',replication resumed in log 'rep_log.003' at position 186510180 020416 18:27:59 read_next_with_key: Got error 126 when reading table ./forum/hardware I think I solved that problem, by upping the openfiles as per your suggestion. (You can of course also get in direct contact with the MySQL developers by buying support from https://order.mysql.com ...) When this persists on AIX, I'll definitely do that. cut Melvyn Didn't find any fields in table 'babbelbox' Have you checked your 'hostname'.err file for errors ? The above error normally means that you have not given MySQL enough file descriptors. This is a common problem on BSD and is fully documented in the online manual, under openbsd. Upped it and restarted mysql. Melvyn Here's the strange part: mysql CHECK TABLE hardware; Melvyn ++---+--++ Melvyn | Table | Op| Msg_type | Msg_text | Melvyn ++---+--++ Melvyn | forum.hardware | check | warning | Table is marked as crashed | Melvyn | forum.hardware | check | error| Found 16426 keys of 16428 | Melvyn | forum.hardware | check | error| Corrupt| Melvyn ++---+--++ Melvyn 3 rows in set (1.33 sec) The above shows the symptoms, but not the reason for the crash :( When you have problems that mysqld hangs, or becomes unresponsible you should definitely look at the following MySQL entries: not applicable. MySQL keeps running - even the slave, which is kindof strange. Melvyn I have a few more tables to go. Melvyn Is there enough room, to roughly upload the binary versions of these index Melvyn files, or doesn't this help you? Melvyn I can upload the 'before' and 'after' version, so you're able to determin Melvyn the difference. If you have something that we can use to repeat the problem, we are interested in looking at this! In this case it's enough to have the original tables + a set of commands to get corrupted tables. Before and after tables will not help us :( I don't get the checksum errors anymore - after I changed the table def. However - myisamchk is not doing a good job with the large keys (restored them by LOAD TABLE hardware FROM MASTER which produced the correct size), plus keys become corrupted when a replication packet is not received correctly, plus: mysql SHOW VARIABLES LIKE '%ft%'; Empty set (0.07 sec) The myisamchck is certainly reproducable, as is the missing ft_ variables, resulting in no way to set ft_min_word_len. Should I re-report those bugs, so they are easier to process for you? Today I think I found something interesting: Some tables kept crashing, with incorrect keyfiles. Verifying the CREATE TABLE statement, there's was 1 correlation: The tables all had a second index on the primary key (for what reason? I don't know - legacy probably - I think the primary key, was dual-fielded at some point). Combining that with the other table that kept crashing there seems to be a problem, with the situation, where one field is indexed more than one time. The first table to crash, did so at a point, where openfiles could never have been a problem, since it was like 6:30 in the morning and no visiting spider anywhere which could have upped the number of open tables.

Let me check - Your_Server_Name I think in my case is localhost I had a look (using the phpMyAdmin tool) at the records in the user table. There are four records - two of which are localhost - one which is root, with password (all privileges), and the second no user no password - no privileges. The other two records are similar, but my server's domain name appears in these two records. I could not see any % mark in the user table - however I did find the % mark in the mysql.host table - two records - one for localhost and the other my domain name, and the % mark was in the db column.

Strange behaviour with SQL vars and order by
Hi, I'm having a strange problem using SQL vars (@variable) and an order by expression. I have a query that returns a record for each day. Each record has a date (data), a column with the daily total value (uv_views) and other with the accumulated value until the current day (acc_views). The other columns are IDs. The problem is that if i only order by date, the results are ok... If i order by date,Site.nome (you would say Site.name) the results are wrong and i don't know where it got those results. Here is the output. I have limited the values to 4 (it only returns rows with 0 but it doesn't matter). In the second big (not so big) query, look at acc_views accumulated value... How can it be ?!?! Thank you in advance for trying to help. mysql select @diario_views:=0,@acc_views:=0; +--+---+ | @diario_views:=0 | @acc_views:=0 | +--+---+ |0 | 0 | +--+---+ 1 row in set (0.00 sec) mysql SELECT data, @diario_views:=uv_views as views, @acc_views:=@acc_views+@diario_views as acc_views, secloc.site_id,secloc.section_id,secloc.location_id FROM secloc,Site,Section,Location WHERE secloc.campaign_id='9' and secloc.site_id=Site.site_id and secloc.section_id=Section.section_id and secloc.location_id=Location.location_id ORDER BY data LIMIT 4; ++---+---+-++-+ | data | views | acc_views | site_id | section_id | location_id | ++---+---+-++-+ | 2001-09-20 | 0 | 0 | 2 | 1 | 4 | | 2001-09-20 | 0 | 0 | 3 | 1 | 4 | | 2001-09-20 | 0 | 0 | 4 | 1 | 4 | | 2001-09-20 | 0 | 0 | 6 | 1 | 4 | ++---+---+-++-+ 4 rows in set (0.02 sec) mysql select @diario_views:=0,@acc_views:=0; +--+---+ | @diario_views:=0 | @acc_views:=0 | +--+---+ |0 | 0 | +--+---+ 1 row in set (0.00 sec) mysql SELECT data, @diario_views:=uv_views as views, @acc_views:=@acc_views+@diario_views as acc_views, secloc.site_id,secloc.section_id,secloc.location_id FROM secloc,Site,Section,Location WHERE secloc.campaign_id='9' and secloc.site_id=Site.site_id and secloc.section_id=Section.section_id and secloc.location_id=Location.location_id ORDER BY data,Site.nome LIMIT 4; ++---+---+-++-+ | data | views | acc_views | site_id | section_id | location_id | ++---+---+-++-+ | 2001-09-20 | 0 |227815 | 3 | 1 | 4 | | 2001-09-20 | 0 |263822 | 4 | 1 | 4 | | 2001-09-20 | 0 | 0 | 2 | 1 | 4 | | 2001-09-20 | 0 |331278 | 6 | 1 | 4 | ++---+---+-++-+ 4 rows in set (0.04 sec) mysql -- dsoares (sql) - 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?

A couple of InnoDB questions
Hi! I run MySQL 3.23.49 with InnoDB tables on a AlphaServer 4100 with 4 x 600 MHz EV5.6 CPUs with 8 MB cache. The machine has 4 GB memory. There are about 8 tables. The tables are small in size (only 1-5 GB each) but has alot of rows (usually 4 million each). There are only a few concurrent select users. Inserts are done by batch from about 70 systems every 5 minute. The systems are spread out during those 5 minute so the inserst come in a constant flow of about 10 per second in average. bin-log is turned off as the machine is unable to keep up with the insert rate with logging turned on. I have a couple of questions related to the cache settings in my.cnf. I need to tune it to give as good a select performance as possible, and also ensure that insert is as fast as possible. The machine ins't doing much else, so I can use close to all memory. Except for the default MySQL table with users etc., I only have InnoDB tables. In the my-huge.cnf example there are some of the settings : set-variable= key_buffer=384M set-variable= max_allowed_packet=1M set-variable= table_cache=512 set-variable= sort_buffer=2M set-variable= record_buffer=2M set-variable= thread_cache=8 set-variable= thread_concurrency=8 set-variable= myisam_sort_buffer_size=64M How many of these needs to be big in relation to a InnoDB only setup ? ...and can I reduce some of them without problems ? I assume the key_buffer isn't used at all since InnoDB has its own, right ? ...and then the InnoDB specific. They are equal (and very low) on all example files : set-variable = innodb_mirrored_log_groups=1 set-variable = innodb_log_files_in_group=3 set-variable = innodb_log_file_size=5M set-variable = innodb_log_buffer_size=8M innodb_flush_log_at_trx_commit=1 innodb_log_archive=0 set-variable = innodb_buffer_pool_size=16M set-variable = innodb_additional_mem_pool_size=2M set-variable = innodb_file_io_threads=4 set-variable = innodb_lock_wait_timeout=50 What would be a good startup for these given my current hardware database ? The database layout and a online interface is available at http://statdb.dassic.com/ for those who want to see the table index design etc. etc. It's not the mentioned machine, but it runs the same database solution. Recommendations related to the solution are welcome...it's OpenSource. /Jesper - 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?

InnoDB data files created but not used...how to fix ?
Hi! A couple of days ago I stopped a MySQL server to change a couple of parameters in the my.cnf file and to add 2 data files (InnoDB). When restarting it, MySQL exited because I'd resized the log file size but forgot to delete/move the old ones. Secondly, I had another error because I allocated more memory than ulimit allowed. I fixed both, restarted, but then it exited because it had created the first datafile with a size of 0. I deleted the ibdata file and restarted, and now it created both data files and started correctly. However, the two new datafiles are not used, and the data they were supposed to add doesn't show up in a show table status. I've later created another data file, and this one works. ...so the question is : How to fix those two ? Can I just shutdown MySQL, rename them and then re-start MySQL and have the files re-created, or is there another solution ? /Jesper - 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: GUI for mySQL
Watch out with using the Jet database engine this way. MS Access tries to keep linked external table views in sync, which means that with large tables and several PCs running Access linked to MySQL over ODBC driver it will bring your network to its knees. The Jet engine will constantly be scanning tables on the database server, generating GIGANTIC amounts of traffic. I've seen 100mb ethernet completely swamped by just 3 or 4 clients. There are probably work-arounds for that, but you should definitely test first, MS Access is a very badly behaved piece of KAKA.

Re: joins vs excess fields
I disagree. Joins can be expensive. Now PERHAPS Tom's suggestion is a good one, but its hard to say. Remember, excess fields can always be left out of a SELECT, so they don't neccessarily cause a performance problem. Some things are true though, fixed length records are more efficient, so if you have varchar fields it might be more efficient to put those in a seperate table. Remember though, when you denormalize like this you risk data integrity and you increase the number of queries your database will handle, which can itself cause a bottleneck. Disk drives for instance can only do so many reads per second, so many small requests for data can cause an I/O bottleneck long before the bandwidth of IDE or SCSI is reached. The only real way to tell if denormalization will help is to try it. build a test database both ways and run some realistic load tests.

So you first search a very compact table where most of the fields are indexes or parts of indexes, and THEN, using primary keys, retrieve big pieces of data which you do not have to search through (and nothing, I guess, works faster in MySQL than retrieval of a single record by it's primary key).

Inserting a BLOB using MySQL++
All, I created a C++ class containing a variety of member variables of varying types such as float, int, char *, etc. If I instantiate an object of this class, how should I insert this object into my database table? I can retrieve the individual members and insert them that way, but I feel it would be more efficient to insert the object as a BLOB, but I don't exactly know how to do that. Basically, I want to insert the object as is so that I can retrieve it as is and not have to bother with calling the member setting functions to populate the class members. I looked at the MySQL++ example for loading a binary file, but am unsure how to apply that to my needs. I also looked through the mail archives and was unsuccessful in finding a solution, so any assistance would be much appreciated. Thanks in advance.

Re: joins vs excess fields
A quick note, I've read Tom's email about using a hanger table and simply don't agree. From: olinux [EMAIL PROTECTED] I have a table with a large number of news articles. For my curiosity, how many article records is a large number? A few thousand, or tens of millions? The question is whether to 1) add a field to the database that most records will not use This is the option that will create the fewest records. If you need to make a single query and be finished, this is the way I'd go. 2) add a table to hold image path names and require a JOIN in order to retrieve. Let's figure what type of JOIN you mean. The MySQL docs seem to indicate that a LEFT JOIN isn't all that bad to run, but my benchmarking doesn't agree. So let's assume you want a straight join. If you were doing that, then you'd only get back articles which have an image path defined because of this type of a joining predicate: articles.id = article_images.article_id In that case, why are you taking the overhead of scanning two tables? Why not scan one table with a predicate like: AND article_type = 'feature' I'm betting that typical usage for you will be a single query something like this: SELECT * FROM articles WHERE keywords like '%good article%' Then you'll display all the records that you've gotten. If this assumption is correct, then I'd strongly suggest compacting your data as much as possible. That is, use one table for data that is on a one-to-one relationship and not related to anything else. Of course, the best thing to do after all of the discussion is to simply try it out. I had a very simular situation a month or two back where I was told that the JOINs weren't a problem. I redisigned the schema in the way that I've indicated and got an improvement of many times (5-12 times faster). In short, we can add up what the docs say all we like, but nothing beats actuall clinical testing. --- Rodney Broom - 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: functions
Good morning Daniel, From: Daniel Jarrett [EMAIL PROTECTED] ...for mysql to perform daily operations.. You bet, it's called 'cron'. MySQL doesn't have anything like scheduling built in. And, arguably, it shouldn't. Since that type of functionality is the responsibility of the operating envoriment and not of the application. If you are using a UNIX like OS, type 'man cron'. If not UNIX, hollar and I'm sure that somebody can tell you how to work it out on your system. --- Rodney Broom sql - 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: New Setup
Hi, OK.If you connect from localhost and use the option -h you must put the alias name from /etc/hosts(if OS is Unix).Try next; use mysql; select Host from user where User='root'; and response is (on my server): %- this is if i wish to connect from any host myx - this is if i wish to connect from myx(is the alias from /etc/hosts) host So now i can try : mysql -u root -h myx I don't use -p because i don't have set the password.

Re: InnoDB data files created but not used...how to fix ?
Jesper, what may have happened is that InnoDB created the data files, but because memory ran out, it did not have time to update the tablespace header to reflect the size increase by those two data files. Later when you added yet another data file, it increased the size stored in the tablespace header. The new data you have added has probably gone to those two data files you added first. InnoDB is aware of the data files you specify, but it thinks that the tablespace size is smaller than the combined size of the data files! What to do? The safest solution is to dump your tables and recreate the whole InnoDB tablespace. If you can afford losing the data in the database, then you can experiment by removing 1 or 2 last files from innodb_data_file_path and look if the database crashes in an assertion failure when you insert new data. Regarding your other question about my.cnf parameter, section 2 of http://www.innodb.com/ibman.html is your best help.

Hi! A couple of days ago I stopped a MySQL server to change a couple of parameters in the my.cnf file and to add 2 data files (InnoDB). When restarting it, MySQL exited because I'd resized the log file size but forgot to delete/move the old ones. Secondly, I had another error because I allocated more memory than ulimit allowed. I fixed both, restarted, but then it exited because it had created the first datafile with a size of 0. I deleted the ibdata file and restarted, and now it created both data files and started correctly. However, the two new datafiles are not used, and the data they were supposed to add doesn't show up in a show table status. I've later created another data file, and this one works. ...so the question is : How to fix those two ? Can I just shutdown MySQL, rename them and then re-start MySQL and have the files re-created, or is there another solution ? /Jesper - 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: joins vs excess fields
Hmm, That's what I thought I was doing by putting the common fields of each article type in a single table. I do need to rethink the search functions. Was thinking of a fulltext index on title and article_content fields. basic table is id | type | author | date | last_update | title | keywords | article_content Since most frequent request will be on the date field, that will be first, but I need to put learn more of fulltext indexes and probably index keywords, title, article content. Thanks much, olinux --- Toomas Vendelin [EMAIL PROTECTED] wrote: Hello olinux, If I were in your shoes, I would put not only paths to images into a separate table, but also a field called content and probably title, summary, author and linked all this stuff together via ID-like fields which are primary keys in those new tables. Then articles table can be searched through much faster, and title, summary, author data can be quickly retrieved using primmary keys ONLY when this data is needed. So you first search a very compact table where most of the fields are indexes or parts of indexes, and THEN, using primary keys, retrieve big pieces of data which you do not have to search through (and nothing, I guess, works faster in MySQL than retrieval of a single record by it's primary key).

Re: MySQL 3.23.44 not using indexes
I have some more information about the problem. It seems to be caused
by the presence of an OR or IN clause in the WHERE portion of the query.
Without the clause, 2.23.44 uses the appropriate indexes, but with the
clause it does not. 2.23.41 uses the appropriate indexes in both cases.
Here are some simple queries that demonstrate this:
2.23.44:

MySQLdb Exception Documentation
Hello All: I'm just learning to use Andy Dustman's MySQLdb for Python. Very easy for this mysql-dummy to learn!

Re: Inserting a BLOB using MySQL++
Probably the best bet would be to write the individual attributes to respective database columns. It keeps a few things simpler. It would also allow you to update the database from multible sources (many threads, or many users on the database). Other wise, you would have to serialize the object to a binary object and write that to the BLOB field. When you imported it back, you would have to deserialize. Some languages call this pickeling. As I have not touched C++ code for a while, I'm not sure what classes are availible to do this for you. The BLOB way of doing it would force you read/write the entire thing everytime you update the object, unless you are just using the database to store it for backup. -Opus On 22 Apr 2002 at 8:21, Thi Cao wrote: All, I created a C++ class containing a variety of member variables of varying types such as float, int, char *, etc. If I instantiate an object of this class, how should I insert this object into my database table? I can retrieve the individual members and insert them that way, but I feel it would be more efficient to insert the object as a BLOB, but I don't exactly know how to do that. Basically, I want to insert the object as is so that I can retrieve it as is and not have to bother with calling the member setting functions to populate the class members. I looked at the MySQL++ example for loading a binary file, but am unsure how to apply that to my needs. I also looked through the mail archives and was unsuccessful in finding a solution, so any assistance would be much appreciated. Thanks in advance.

Re: functions
For NT and 2000 machines, use the AT command if you want a command line scheduler. The syntax is actually different between them though.

Re: functions
Actually, W2K has a scheduler built in that works pretty well for basic scheduling needs. If you are using NT 4.0, try and upgrade to SP6a. That SP has the scheduler of W2K built in as well.

Having lots of tables
Hi, I have a question on a project i am currently on. I am adapting Phorum (www.phorum.org) to my own portal and have a doubt about MySQL. Phorum creates a table for each discussion forum. However, in the portal i work for, i currently have thousands of items that would potentially need a table (with a very little amount of records, rarely more than 10). I am talking of a maximun of 1 tables. Is there any reason to avoid having a large number of tables (which have the same structure)? Are there any considerations that I should have? Would doing just-one-big-table (with a forum-id) be advisable?

C MYSQL Struct
I am having trouble accessing the data in the MySQL struct for C (included in the mysqlclient libraries). I am specifically unable to access the *fields (array?) within the struct. My program fails with segmentation faults whenever I try to access any variables within *fields. Does the mysql_init( ) function or mysql_connect( ) function allocate memory for this variable. How does one access the data stored in *fields?

Re: Having lots of tables
From: Agustín Fernández [EMAIL PROTECTED] Is there any reason to avoid having a large number of tables (which have the same structure)? You might run into a limit on the number of open file handles, but you'd have to check the MySQL docs for how he handles it, and possibly your OS docs to see what the limit is. Would doing just-one-big-table (with a forum-id) be advisable? Very possibly. 100,000 records isn't huge, but it could be big enough to put a load on your machine. Unless you find a definative answer in the docs, I'd try testing both. --- Rodney Broom Programmer, R.Broom Consulting - 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?

table lock - which connection id own's it
AntiSpam - mysql, sql, query Version: 3.23.49a, MyISAM, NT, Solaris My app is 150 daemons writing logs to mysql. The main table is of fixed size but depends on four other tables for foreign keys (hash tables). These tables are uploaded once to the daemon at start-up. Occasionally, a new entry must be written into these hash tables. The procedure is to lock the table, insert entry, get the key (auto-increment field) and release the lock. But what if the connection dies during the update process. If this happens, how can I tell which connection id has the lock so I can kill it? I have tried: show full processlist - shows connection id's - no lock info show table status;- will not display until lock is removed show open tables - shows open table with comment in_use=1 but this could be normal operation. My understanding is that the lock will be removed once the connection dies (sql command kill id or the server terminates connection via timeout). I would to detect when the lock is on for a long period of time. Any ideas? Suggestions?

aggregate functions, source code
Hi, I'm trying to convert a database I have from M$ Access to Mysql. I've done this pretty successfully but have come across a couple of sticky problems. I have been using first last aggregate functions within Access for some certain complex queries. It would make my life a lot simpler and more efficient if I could create/find a similar function with mysql. I have spent the last couple of days searching the net for some information on this issue and have found that short of writing my own in gcc I out of luck. I have managed to compile the udf_example.cc libraries that come with Mysql. I was wondering, has anyone out there got some source code for a first last function? I haven't done any C programming for 7+ years and even then it was only minimal. So I'm only a newbe in that area. I would love to get our database ported to Mysql but without this its going to make it pretty difficult. Ideas or alternative solutions anyone?

Question about mysql++ and g++
Ok, i downloaded the mysql++-1.7.8-1.i386.rpm
ftp://ftp.rpmfind.net/linux/MySQL/mysql++/mysql++-1.7.8-1.i386.rpm rpm
file from RpmFind.net. I have mysql installed already on my machine, o
ya and im running linux. I have gcc installed, version 2.96, i think
everything installed correctly when i ran the rpm. But i am not sure. I
made a simple program, here it is:
#include sqlplus.hh
int main() {
return 0;
}
When i tried to compile it using g++ mysql.cpp i got a bunch of errors
saying mysql.h not found (errors are printed on bottom of email). So i
tried doing a locate mysql.h and it only found the mysql.h file from
my windows partition (i have mysql++ installed on windows...).
I am not sure if its my compiler, or the version of mysql++ i installed.
Another question i have is it says to reset my database using reset-db,
where would i do that? The mysql command line?
If anyone can help me, give me some ideas if my install went wrong, or
if i need to update gcc, or get a different compiler (i dont know any
for linux yet! ) id appreciate it very much!

It's not pretty, but it's totally harmless. NOTE: There's always -some- weirdness that goes on with threads implementations between different systems. On Linux, this is it. -M On Tue, Apr 23, 2002 at 11:51:49AM +0800, Patrick Hsieh wrote: I have 38 mysqld processes running in one single machine, is it normal? 11:48:43 up 49 days, 15:11, 34 users, load average: 0.02, 0.06, 0.00 275 processes: 265 sleeping, 1 running, 9 zombie, 0 stopped CPU states: 3.2% user, 4.3% system, 0.0% nice, 92.5% idle Mem:900464K total, 840808K used,59656K free, 277532K buffers Swap: 498004K total, 327808K used, 170196K free, 221132K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 31277 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:04 mysqld 31279 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:07 mysqld 31280 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31281 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31282 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31283 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31284 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31285 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:12 mysqld 31286 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:02 mysqld 31287 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:01 mysqld 31288 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:00 mysqld 31738 mysql 9 0 300M 30M 3004 S 0.0 3.5 4:11 mysqld 7110 mysql 10 0 300M 30M 3004 S 0.5 3.5 6:22 mysqld 12137 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:59 mysqld 16802 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:02 mysqld 16841 mysql 9 0 300M 30M 3004 S 0.0 3.5 0:02 mysqld It seems mysqld has used all of my memory.

Re: MySQL 3.23.44 not using indexes
A search for 'indexes' brings this as the first result: 5.4.3 How MySQL Uses Indexes http://www.mysql.com/doc/M/y/MySQL_indexes.html Inside the page: Any index that doesn't span all AND levels in the WHERE clause is not used to optimise the query. In other words: To be able to use an index, a prefix of the index must be used in every AND group. [Note: optimize is spelled wrong in the manual.] The corollary to the above quote is that MySQL can not use indexes with an OR clause at the base level. It would be a worthy optimization to make. MySQL could order the items in the OR clause of the query, skipping ahead when one section is complete and on to the next (assuming a single index would be used). Or it could internally create a temp table and break the WHERE clause into several smaller queries that do use indexes. In fact, you can do that yourself as well (either using temp tables or UNIONs in version 4). Makes for messy SQL writing to work around this optimization issue, so I'm sure someone will add it to MySQL some day. Maybe it will be you! :) Sincerely, Steven Roussey http://Network54.com/?pp=e - 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?
