Thanks. In 3.23.32 the test case I submitted apparently works better,
but bad things still happen, like the following table corruption:
DROP TABLE IF EXISTS t1;
CREATE TABLE t1 (
id mediumint unsigned NOT NULL auto_increment,
tag char(6) NOT NULL default '',
value text NOT NULL default '',
PRIMARY KEY (id),
KEY kt(tag),
KEY kv(value(15)),
FULLTEXT KEY kvf(value)

DROP TABLE IF EXISTS t2;
CREATE TABLE t2 (
id_t2 mediumint unsigned NOT NULL default '0',
id_t1 mediumint unsigned NOT NULL default '0',
field_number tinyint unsigned NOT NULL default '0',
PRIMARY KEY (id_t2,id_t1,field_number),
KEY id_t1(id_t1)
) TYPE=MyISAM;
INSERT INTO t1 (tag,value) VALUES ('foobar','baz');
INSERT INTO t2 VALUES (1,1,1);
CHECK TABLE t1;
The error says: "Can't read indexpage from filepos: -1". Moreover,
myisachk isn't able to repair it! (neither -r nor -o).
Tested on both sparc64-linux (sun4u) and sparc-solaris2.6 (sun4m).

In other words it remains to be seen if the 2.4 kernel paired with glibc-2.2 resolves my current problems where mysql goes belly-up under load.

RE: Insert problem in MYSQL with PHP
This has nothing to do with PHP, and you should never expect a relational database to store records in a specific order. If you need to order your data, you should create a key field.

Re: write problems via MS Access 97 in table with timestamp andprimary key
One of our users is getting the message "another user has changed this database..etc save changes to clipboard or drop changes... etc", when he tries to update certain fields in the table. The table has a timestamp and a primary key. In fact, this user can change certain fileds without difficulty for certain types of data and not for others (i.e. Access accepts changes when the data is a document but not when its a collection). To make things more confusing., other users can change all fields in the same table via Access without receiving the error message. Any one else had and solved this problem? Susan Albright Ma'am, this is an ODBC problem, not a MySQL problem. I assume that the table is a linked table in Access. How is it accessed? Directly, through a query, or through a form? Are there any joins? Does the problem occur only through a query or form that joins the table with another table? What do you mean by 'the data is a document' and 'its a collection'? These aren't MySQL or Jet datatypes. What is the user who's having problems doing that the other users aren't doing? Things that people have done to solve this include dropping and adding primary keys and timestamp fields, setting up relationships between tables as much as possible (you can set up a relationship between linked tables, but I don't think you can specify what the relationship is), and selecting UniqueRecords in queries (DISTINCTROW in SQL).

Re: Junction entities VS. JOIN
Thanks. (I don't know where I was coming from with the JOIN stuff, should have gone to bed hours ago) However, you don't think I should have the "ab_id" column, which would be the standard serial primary key for a table. Does a junction entity table not need it's own record ids? Technically, it shouldn't, but does good db form require it? or is a junction entity normalization table exempt from that? thanks again --Dylan Shea "Carsten H.

The other is you'll want to grab the MySQL updates due to security issues and bugs in the version of MySQL in the Abriasoft package. b.t.w. I was using the the RH7 Linux version. Installing Abriasoft SQL on top of a fresh RH7 install will solve you a lot of hassle due to bugs in key RH7 packages. --Dylan Shea "Frank J.

Re: Can't compile on Solaris 2.7
Chuck I'm trying to compile 3.23.31 on Solaris 2.7 also, and had the same problem. If you either delete or rename the config.cache file, this will go away. The config.cache file supplies default values to the configure script, and those default values weren't suitable for our Solaris installation. Deleting (preferably renaming) the config.cache file forced the configure script to build its own cache file. If your OS installation is like ours, you may have later problems when configure attempts to determine the size of a char variable. You'll need to have the directory containing libz.so in your LD_LIBRARY_PATH. I'm still not finished with my source installation. Now my Makefile won't complete. Arrggh!

Problems making source dist. on Solaris
Hi all, I'm making a source distribution on Solaris.

A quick look in my libmysql directory shows nothing there but these files: Makefile Makefile.am Makefile.in Makefile.shared acinclude.m4 configure.in Meanwhile, in my libmysql_r directory, there are lots of .c files, including libmysql.c, but these are links that point to files in the libmysql directory that don't exist. For example, libmysql_r/libmysql.c is a link that points to libmysql/libmysql.c, which doesn't exist. My configure script seemed to run OK. Anyone have any ideas? Thanks.

Index question
Say I have a table called Discharge that is indexed on Vessel + Voyage + Port (Primary Key). It has thousands of records in it and continuously grows. I now want to delete records where Vessel = "USS ENTERPRISE" Voyage = "005" I want to delete all records with the above Vessel/Voyage. There can be anywhere from 1 to 20 records with that match (different Port). My SQL statement is: DELETE FROM Discharge where Vessel = "USS ENTERPRISE" AND Voyage = "005"; My question is one pertaining to performance. Will MySQL scan through the entire table or will it utilize the index and quickly delete all record with the above statement? If the former, what would be an efficient and quick way to delete records of a partial key?

isamchk and myisamchk inconsistently report errors

The utility reports a miscellaneous error (error: Record at: 20224201 Can't find key for index: 2 for example). I run the check again immediatelly and the error has dissapeared. I assume simply doing a check is a read only operation so how is this possible if the data file is not changing? I went as far as doing a diff on tables before and after the check to make sure nothing changes and it seems to be read only. I have also made absolutelly sure the database is down so nothing is writing to the files.

if you've compiled php without apache support (separately from your normal php with apache support) but with mySQL then you can write php scripts that run from the command line. I usually keep a second php.ini for command line scripts because they can run long. This all could be put in a CRON job. 'course you could do it in PERL as well.

Re: write problems via MS Access 97 in table with timestamp and primary key
I used to get this all the time, myself, when I was trying to update a mysql database with Access 2000 through myodbc. Funny, at the time, nobody else seemed to understand what I was talking about. Once I got phpMyAdmin working, the problem became academic, but it never did get solved. I'm still trying to find a solution to my $FORMATQUERY ORDER BY problem with a logic function on two values. Baring a solution, I can only hope for a workaround before a year of effort is not wasted, because someone else beat me to market. Please, this does not need to be a volunteer effort. If anyone thinks they can solve this, contact me directly and we can work something out.

The table has a timestamp and a primary key. In fact, this user can change certain fileds without difficulty for certain types of data and not for others (i.e. Access accepts changes when the data is a document but not when its a collection). To make things more confusing., other users can change all fields in the same table via Access without receiving the error message. Any one else had and solved this problem? Susan Albright Ma'am, this is an ODBC problem, not a MySQL problem. I assume that the table is a linked table in Access. How is it accessed? Directly, through a query, or through a form? Are there any joins? Does the problem occur only through a query or form that joins the table with another table? What do you mean by 'the data is a document' and 'its a collection'? These aren't MySQL or Jet datatypes. What is the user who's having problems doing that the other users aren't doing? Things that people have done to solve this include dropping and adding primary keys and timestamp fields, setting up relationships between tables as much as possible (you can set up a relationship between linked tables, but I don't think you can specify what the relationship is), and selecting UniqueRecords in queries (DISTINCTROW in SQL).

Monty was cleaning up my code and accidentally introduced the bug, but
unfortunately, at that time we did not have a test case for starting the
slave with existing master.info without reset or change master to, so the bug
slipped by. Now I have added a test case for this ( rpl17), so if
somebody decides to "clean up" that code again, we can catch this.
The bug only happens when you restart the server - SLAVE STOP/SLAVE START
will work ok. If you do not want to patch, downgrade or wait for 3.23.33, the
workaround to restart a slave is:
* cat /path/to/datadir/master.info
* get the log name and the offset
* start the slave server
* CHANGE MASTER TO MASTER_LOG_POS=saved_position,
MASTER_LOG_FILE='saved_log_name'

Does the RAM size have to provide for both the MYI and MYD files? Yes. You will need around 1gig available mem to load that table! You have not included the structure of the table, so the table could have fixed row lengths. This can make a table very large indeed. Are you using varchar or char columns?

RE: Doing multiple updates
Sounds like you want a mutex and you can use get_lock and release_lock in
mysql for that.
http://www.mysql.com/doc/M/i/Miscellaneous_functions.html
GET_LOCK(str,timeout)
Tries to obtain a lock with a name given by the string str, with a timeout
of timeout seconds. Returns 1 if the lock was obtained successfully, 0 if
the attempt timed out, or NULL if an error occurred (such as running out of
memory or the thread was killed with mysqladmin kill). A lock is released
when you execute RELEASE_LOCK(), execute a new GET_LOCK(), or the thread
terminates. This function can be used to implement application locks or to
simulate record locks. It blocks requests by other clients for locks with
the same name; clients that agree on a given lock string name can use the
string to perform cooperative advisory locking:
mysql select GET_LOCK("lock1",10);
- 1
mysql select GET_LOCK("lock2",10);
- 1
mysql select RELEASE_LOCK("lock2");
- 1
mysql select RELEASE_LOCK("lock1");
- NULL
Note that the second RELEASE_LOCK() call returns NULL because the lock
"lock1" was automatically released by the second GET_LOCK() call.
RELEASE_LOCK(str)
Releases the lock named by the string str that was obtained with GET_LOCK().
Returns 1 if the lock was released, 0 if the lock wasn't locked by this
thread (in which case the lock is not released), and NULL if the named lock
didn't exist. The lock will not exist if it was never obtained by a call to
GET_LOCK() or if it already has been released.
Mark.

RE: Doing multiple updates
Randy, My recommendation (and there are probably many people who will disagree with me) is to use a "soft-lock" schema. In your account table, add a field named lockedBy. I usually add a field named lockedAt also as a timestamp. the basic flow is this: 1: Check to see if the record has something in lockedBy -NO- 2: Update the record with your userID 3: Check to see if there record has something in lockedBy and it is you. -YES- 4: you have successfully soft-locked the record for update. Go ahead and make your update 5: update the record to remove the lock. WARNING: This system assumes that you have control over all processes that access the database. If there is a chance that someone will come in and be able to modify the data outside of your code then they can bypass your checks and modify the data. In many DBMSs (not sure yet about MySQL) record locks keep people for even seeing the data and some (M$ SQL) used to lock whole tables to do a single update.

RE: Doing multiple updates
Sounds good. You should probably have a cleaner process of some kind just in case one of your threads dies before it can release the lock. I think with get_lock you have a timeout that protects you from that. I'm curious about the internals of get_lock - perhaps it's more efficient to use a soft lock like you've described. I dunno. -Original Message- From: Cal Evans [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 24, 2001 9:10 PM To: Randy Johnson; [EMAIL PROTECTED] Subject: RE: Doing multiple updates Randy, My recommendation (and there are probably many people who will disagree with me) is to use a "soft-lock" schema.

Can anyone point me to a mailing list/usenet group where I can ask lots of dumb newbie SQL questions w/o making a major pest of myself?

RE: rank newbie looking for SQL forum
Hi Jason, You have found the right place. No one here minds you asking simple questions, so long as you have checked the manual and the list archive before asking. In particular, Red Hat installs are a frequent topic. This list is supposed to be MySQL specific, but sometimes we get a little side-tracked. Welcome to the MySQL Community - I hope you have as much success with it as we have.

Re: Sizing HEAP table using .MYD/MYI
Hi, If my calculations are correct, your table will grow quite a lot if you change from the MyISAM format to HEAP. The space to hold the data will be roughly 1.3GB (a double of what it's with MyISAM!) and the index will be another 1.3GB. Pretty huge, isn't it? I think the dynamic row format is appropriate for your table. BTW, running OPTIMIZE on your table could speed things up, the figures you post indicate that the table is heavily fragmented. Also, an ANALYZE never hurts. Perhaps you could try to move it to a RAM disk (in MyISAM format), that shouldn't eat up that much space as the HEAP format. If you can live with a read-only access to the table, at least for some time, you should consider using the myisampack utility to compress the datafile. Then it's actually very fast to have the table on disk, too, because with enough RAM, the keyfile is buffered in MySQL key cache and the data is mmap()'ed to memory. This should be as fast as a RAM disk. If you only need to update a small portion of the table, you could consider using the MERGE virtual driver, with the basic part myisampack'ed and the changeable part in plain MyISAM. But that might slow things down a bit. You could also reconsider the table design. Is it really so that the varchar(60) field is the primary key? Are there any other tables that refer to this one with a foreign key? (The foreign key should then be also a varchar(60), which would probably be a killer.) Jan mike thomas wrote: Richard Thanks for the info! I have just one more question. To get the structure of the table I did a myisamchk and did a desc on the table. The output is shown below. From this is it possible to determine the amount of RAM I would need for a HEAP table? Thanks!

I understand (from previous posts) that I must create a HEAP table. Please correct me if I'm wrong on this. My question is - how much RAM do I need if the MYI and MYD files are as follows :- 214M Jan 20 19:11 domain0115.MYI 680M Jan 20 19:11 domain0115.MYD Those sizes are in Mega bytes. Does the RAM size have to provide for both the MYI and MYD files? Yes. You will need around 1gig available mem to load that table! You have not included the structure of the table, so the table could have fixed row lengths. This can make a table very large indeed. Are you using varchar or char columns? Also, is it correct that the MYD is the datafile and MYI the index file? Yes. -- Richard Ellerbrock [EMAIL PROTECTED] - 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?

Hi,
as far as I can see that, you forgot the $ sign in front of the odbc_db
variable at the line, that causes the error.

I have a couple of questions regarding replication in MySQL: 1) does it work well/handle loss of connections due to network outages/delays; we have a geographically diverse environment, and were hoping to be able to replicate the data across the connections (which may have outages from time to time) 2) Is it possible to set the hosts up in the following manner, where Host [1,2,3] all recieve data updates that should go to all other hosts Host[A,B] recieves updates from Host 1, and updates some tables only to Host 1(client data) Host A \ Host 1 --- Host 2 --- Host 3 / Host B Host 2 is in the network between Host 1 and Host 3 I know it is possible to set up replication in a circular mode, but I haven't heard/read of any way to configure them in a chain or star configuration (Host 2 would be a slave to Host 1 and Host 3) and Host 1 would be a slave to A,B and 2 Also, each of these hosts is in a different geographic location, so it would be nice to have some redundancy and load balancing at some sites (Host 1.1, 1.2, 1.3, etc) based on query load.

I get this error sometimes if my permissions are set wrong. If the data directory is readable, for example.

Hi,
as far as I can see that, you forgot the $ sign in front of the odbc_db
variable at the line, that causes the error.
bye,

Ideas??
Hi, I am creating a web site which allows users to post projects and then others to place bids. I am setting up two tables in MySQL 'Projects' 'Bids' my problem is how best to cross reference. What I was thinking of doing is creating a number of fields in the Projects table... Bid1 Bid2 Bid3 etc and then inserting the BidID from the bids table into Bid1, and if that is already used then it will go into Bid2. But how many Bid# shall I create?? I`m sure there must be a faster method than this, anyone have any suggestions??
