Re:crashes when executing query on innodb table; probably corrupted table
Hi! In 3.23.41 there was a serious BLOB bug which corrupted the table if you updated the primary key of a long row. There was also another bug in 3.23.41 which could crash a query if you selected two long columns in the same query. There is a special page for bug reports at the InnoDB website: http://www.innodb.com/bugfixes.html That often helps in this kind of situation. These bugs are fixed in 3.23.42.

New to MySQL and I've got a question. I have an application that does a good deal of hierarchical reporting. In order to do this one of the tables in my database contains nothing more than an individuals id and the team to which that individual reports TABLE - TEAMREPORT e.g. Individual ID(PK,FK) Team ID _ |1 |123 | _ |2 |123 | _ |3 |456 | _ |4 |789 | _ |5 |789 | _ I can get much more information by linking this table to another table: TABLE - INDIVIDUAL IndividualID Date Name Manager _ |1|2001-09-01|Smith |1 | _ |2|2001-09-01|Black |0 | _ |3|2001-09-01|Anderson |1 | _ |4|2001-09-01|Paul |1 | _ |5|2001-09-01|Wells |0 | _ (The Manager field tells me if that person is the manager of the team; 1=Manager, 0=NotManager) So if I wanted to find out what team individual #4 reported to I would simply SELECT TEAMID FROM table WHERE INDIVIDUAL ID = 4. If I wanted to find out who was the manager of team 789: SELECT I.Name FROM TEAMREPORT T, INDIVIDUAL I, WHERE T.IndividualID = I.IndividualID AND Manager = 1. Of course the problem at hand is a little more complex. It is possible to have more than 1 level of hierarchy. In other words, team 789 reports to team 123. So, in plain English, Individual 5 reports to Team 789 which, in turn, reports to Team 123. What I would like to find out is, if I start with individual #5 and #5 reports to team 789, which also reports to team 123, who is the Manger of team 123 (I need the manager 2 levels up rather than 1)? Of course a subquery would be ideal in this situation, but obviously this cannot happen. I know that many subqueries can be turned into a join (or multiple join) statement but I cannot figure out that statement for the life of me. I'd hate to turn one query into two, but at this point my SQL inexperience is forcing me to do so. Any SQL wizards have any ideas? If I was using Oracle, the CONNECT BY clause would be an option. Is there anything similar in MySQL? Hope this makes sense and I would love to hear any thoughts.

Date entry problem after upgrading to MySQL 3.23.42
Hi, I've just upgraded from MySQL 3.22.32 to MySQL 3.23.42 and almost all of my date related database entry tables have broken. I have been submitting datetime's in the format 2001 09 25 11:35:00 to a standard Datetime field and now after upgrading to MySQL 3.23.42 datetime's entered in this format are appearing as -00-00 00:00:00 in the database. Entering dates as 2001-09-25 11:35:00 fixes the problem but it will take ages for me to find all entries which use this code. I have potentially hundreds of references across many sites which have been broken by this Is there a way it can be fixed at the server end ? Otherwise it may be weeks until all references to this code can be eliminated. Thanks in advance.

Re: Use of MySQL with large tables
We have a table with over 27 Million rows and have had trouble with the JDBC with large queries. Our solution has been to use loops with a more restrictive where clause. Its not mission critical so I have not investigated very sincerely. But I recently ran across the --quick option for the mysql client. We began to implement this, but noticed that it prevented large updates ( 50,000 rows) when using our application, so we had to turn it off, but it might work for you. Kevin Kotun Hydrologist Everglades National Park We are encountering two issues when using MySQL with large tables (by large, we're talking 1 million rows). Our application is written in Java and we are using the mm.mysql JDBC driver. We run our applications using both Oracle and MySQL. Below are issues that we have experienced. 1. The mm.mysql driver caches all results from a large selection in memory before returning the ResultSet to the calling method. This means that any select returning a lot of rows runs the risk of getting an OutOfMemoryError. Oracle doesn't have this problem, as the ResultSet only contains some of the rows matching the query, and more are retrieved as ResultSet.next() is called. One of our developers has already discussed the issue with Mark Matthews, and the impression seems to be that MySQL does not support true cursors. Once you start a query, you must read the entire result set before issuing any other queries. The lack of cursors seems to really limit what types of applications can be implemented using MySQL as a backend. Are there any discussions regarding the implementation of cursors which would support canceling and scrolling, or is the solution to just keep adding memory (we're running on a PII 450 w/ 128MB RAM)? 2. After we incurred problem number 1, we decided to work around it by using the LIMIT directive and retrieving the entire table in chunks of 25000 rows by issuing a series of queries. Unfortunately, each LIMIT query takes longer and longer to return results, which means the overall select proceeds in exponential time. As an example, we tried to query all of the rows for a table containing 18 columns with 1.8 million rows (on a PII 450 w/ 128M). A partial summary of the results is in the following table: Selected rows Time for this selectCumulative Time 0-24999 00:00:2900:00:29 25000-4 00:00:3000:00:59 5-74999 00:00:3200:01:31 ... 50-524999 00:05:5201:01:04 525000-54 00:06:0301:07:07 ... 100-1024999 00:11:1003:50:07 ... 1775000-179 0:27:50 14:15:34 Is this phenomena expected behavior and will it be addressed sometime in the future, or is it just the way it goes?

Update Logging on Windows 2000 Service
Hello I need to setup update logging for Mysql running on Windows 2000, I read in the manual that this cannot be done when you are using mysql as a service (as any startup parameters are ignored). Ideally I would like to do this, so if the machine is restarted mysql starts automatically as a service. Does anyone know if there is a craftly way to do this?

Upgrading Mysql from 3.22 to 3.23
Hi there, Looking at upgrading from version 3.22.27 to the current release of 3.23 on Solaris 2.7 platform. We successfully built from built the 3.22.27 and looking to do the same with 3.23. Are there any gottcha's out there that I should be aware of? I looked at the Mysql documentation and see in the upgrade information on what changes there are in the new server ( http://www.mysql.com/doc/U/p/Upgrading-from-3.22.html) . I guess what I'm looking for is the upgrade instructions on how to do the upgrade (building compiling, and installing) a step by step if there is one over an existing Mysql install? Or does the install process just overwrite the old Mysql version if installed in same directory?

Re: [Q]How to delete recursively
In MySQL the best (only?) solution I know of is to write a script (e.g. in
perl or python) that will traverse the tree for you.
e.g:
select a_keys from A
foreach key ( a_keys ){
select c_keys from B
... etc.
delete from b where key in ( a_keys )
If you were really looking for punishment you could create a table of
meta-data that descibed how the tables were related and then use that to do
the cascade delete. And of course, LEFT JOIN is your friend for finding
reocrds in lower tables that do not have a matching reocrod in the parent
table, e.g.: SELECT b_keys FROM B LEFT JOIN A on ( common_key ) where
A.common_key IS NULL;.

Hi.

There is hierarchy among groups listed below like directory structure.

I want to delete A group. This requires deletion of all child groups.
Above figure is a little simple but if this tree grows large that's my
problem.
Would you please tell me the answer?
For reference table is like this.
Field Type
groupname varchar(50)
groupno int
p_groupno int - This means parent group no.

Does NetKnow have some - site specific - instruction how to set up a
database and MySQL user privileges? What are the assumptions and
restrictions? What NetKnow will set up and what I'm supposed to set up?
Thank you

database documentation
What tools do people use to document their databases? Are there graphical tools that will generate relational diagrams of a database (like in Access)? One of the databases I've been developing is starting to grow as I add additional tables to hold different pieces of data. At the moment, my documentation comes from adding comments and CREATE statements to the result of an earlier mysqldump file. Back when I only had 7 or 8 tables, this was fine, but now my database is starting to approach 25 tables, so some of the relationships are starting to get a little hard to keep track of.

RE: RE: Info Needed to Promote MySQL!! - Solved
What I did to handle global changes was have one access file on the fileserver that everyone had a shortcut to. That way the updates were global since they were all to the same file. How is the speed of running Queries, Forms and Reports from Access using linked tables to MySQL? I've found it quite slow. Tasks that use to take a few seconds now takes 3 minutes or more.

Is there a way to have this update done on linked tables automatically and is it possible to have this done on a global scale.

MS Access Links to Mysql
Hello again folks
I am using MS Access as the front end to my database, but after a while of
use, I get a prompt as follows, when I try to close a table in datasheet
view or when I try to close a form:
The action will reset the current code in break mode {blah blah blah}
Then I have to choose yes or no.
(I don't have any VBA code running that could be halted anyway when this
happens)
Either way this doesn't close the object I have open and I have to resort to
killing the application from the task manager.
Does anyone else have the same problem?, anyone have any ideas of how I can
overcome it?
Thanks for any help.
John.

Re: copy tables to another db
There are a number of ways to do this. Not being sure exactly what you want, a live copy (replication) or a transfer (mysqldump), it's tough for me to say which method would be best. Look in the manual under mysqldump or replication and see if those fit your needs.

Re: database documentation
From: Ravi Raman [EMAIL PROTECTED] if you (or anyone else) finds/has found anything better i'd be interested to know. I've used Visio here and again, mostly V.6. It involves a lot of legwork since I have to manually deal with all of the lines representing relationships, but it creates a very nice output that I can export in many formats. I know that Visio Professional 5.0c can use some interesting relationship tools that handle most of the line manipulation between items. I've tried the same tools in later versions and they plainly didn't work (erred out). I've thought of getting and installing that older version just for the DB support. I've also looked at several levels of software on these download sites. Not even the pay-ware offerings looked worth having. My Dad sais that ERWin is very powerful and suggested that I buy myself a copy. Then I heard that it runs about 3K and opted not to. --- Rodney Broom Programmer: Desert.Net Spam filter: 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?

REGEXP and PHP Forms
Hi listfellows!
Okay, I'm trying to make a form talk to a SELECT query using PHP. How do I
make input from a form become a PHP variable?
This is how far I've gotten:
?php
function search_records() {
?
form name=form1 method=post action=?php echo
$PHP_SELF?action=list_recordstitle=$formtitle; ?
input type=text name=$formtitleinput type=submit
name=Submit value=GO
/form
? } ?
Now underneath this I have a function list_records() with a page that is
supposed to list the records.
$query = SELECT title FROM $user_tablename WHERE title REGEXP '$formtitle'
$order_by_str $sort_order_str $limit_str;
This will work if I tell it to select all the records and display them, but
if told to use the $formtitle information it says empty (sub) expression
from REGEXP.
Any help is appreciated! Thanks!

Re: [Q]How to delete recursively
What I say will not help you since this is a MySQL limitation. However, on
more fully-featured SQL systems, you can specify a referential constraint that
will delete child rows when the parent row is deleted.
You might have something like this on table C (assumes table A is the master):
create table c (
groupno int not null
constraint cgroup_ref
references a
on update cascade
on delete cascade,
otherfield...
This creates a referential constraint between tables A and C. Now, what
happens is you cannot even create a new groupno in C until it exists in A.
This assures the database does not have orphaned child rows.
Then, when you delete from A where groupno=1, the groupno delete will
propagate downward to all tables that have a referential constraint of DELETE
CASCADE automatically. (This is handled by the database engine, not the
application.)
One question I have about your table diagram below is: are tables A and B
really joint owners of the groupno? It would be even better if a SINGLE table
was the master that owned the groupno. When/if MySQL offers referential
integrity, you could take advantage of the above.
Don't get me wrong, I'm not disparaging MySQL. I use it on my personal website
and dabbling with web applications with it and PHP. But, I work with 2 other
database systems on a daily basis (DB2 and MS-SQL Server) that allow the above
solution to your problem.
HTH,
Loyd

In MySQL the best (only?) solution I know of is to write a script (e.g. in

... etc.
delete from b where key in ( a_keys )
If you were really looking for punishment you could create a table of
meta-data that descibed how the tables were related and then use that to do
the cascade delete. And of course, LEFT JOIN is your friend for finding
reocrds in lower tables that do not have a matching reocrod in the parent
table, e.g.: SELECT b_keys FROM B LEFT JOIN A on ( common_key ) where
A.common_key IS NULL;.

For reference table is like this.

Disk-bound joins
Hi all, I have two very large tables (4 million recs each) where the records from each have a 1-to-1 relationship. They share a primary key (int) and there are no unmatched records in either table (i.e. it is a true 1-to-1). I am trying to combine a few columns from each of the two tables into a new third table. No matter what I do, the select statement process becomes disk-bound (low processor utilization despite no competition, tons of disk activity, excrutiatingly slow). Why is this? Has anyone else encountered this kind of trouble? I have gobs of memory (1.25Gb) and I am using the settings from my-huge.cnf. I have a reasonable processor - 733Mhz (not that its doing anything). I have a ATA-100 IDE hard disk, on a dedicated controller completely devoted to mysql. I am using mysql 3.23.41 on Win2k. My tables are as follows: CREATE TABLE zipwork1 ( runid int not null primary key, zip char(5), plus4 char(4), addrerr tinyint ); /* This table has 4,014,438 records */ CREATE TABLE pctwork1 ( runid int not null primary key, cnty char(3) not null, precinct char(3) not null, cd tinyint, sd tinyint, hd tinyint ); /* This table also has 4,014,438 records */ CREATE TABLE zippctmapwork ( runid int not null, zip char(5), plus4 char(4), addrerr tinyint, cnty char(3), precinct char(3), cd tinyint, sd tinyint, hd tinyint ); /* This is the table I am trying to populate (starts out empty) */ Here is my statement: INSERT INTO zippctmapwork (runid, zip, plus4, addrerr, cnty, precinct, cd, sd, hd) SELECT z.runid, z.zip, z.plus4, z.addrerr, p.cnty, p.precinct, p.cd, p.sd, p.hd FROM zipwork1 AS z INNER JOIN pctwork1 as p ON z.runid = p.runid; This is taking almost 20 minutes to execute. 20 minutes is great compared to when I try this on the 2 tables that zipwork1 and pctwork1 are originated from (zipwork1 and pctwork1 are subset tables I created to try and speed this thing up). When I ran it on the original tables, I had to kill it after 100 minutes and it had not even begun writing to the result table yet. Anyone have any ideas... anyone?
