Mysql vs MySQL max
Hi Probably a stupid question, but which is best to have on ones server, the old mysql, or max. I.O.W, if you install MAX and never use innodb or berkeley tables, will it be equivalent to a normal mysql installation wrt performance and stability? I'm asking from an ISP's point of view, if that makes any difference ( obviously if from developer it will depend on the needs of the app..)

Hi All In MySql 3.23.51 , i was able to add values into the child table I have created a table parent and also another table child where parentid column in child is a foreign key to the id column in parent table It was possible that i have no entries in parent table , and i was able to insert null values for parentid in child table.. This was a feature in 3.23.51 whereas this was not available in 3.23.49 When i tried MySQL 4.0.1 , i was shocked to see that i was not able to insert null values in the child table which was supported in 3.23.51 Any ideas -Arul sql,query - 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: high level: enabling transactions in mysql-max with WebLogic TX datasource?
Hi, all you have to do use a transaction enabled data-source and use the Mm-MysqlDriver for your JDBC connections. (http://mmmysql.sourceforge.net/) Best is to read the InnoDB documentation carefully (http://www.innodb.com), as you cannot choose from a wide variety of transaction-levels ... in my experience, most of the detailed transaction-handling can only be done at mysql-query level. To test wether your datasource supports the transactions, do a test and look at the InnoDB-logfiles, it should indicate some thing like SET AUTOCOMMIT=0 and COMMIT. Greetz, CB. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Sunday, June 30, 2002 22:33 To: [EMAIL PROTECTED] Subject: high level: enabling transactions in mysql-max with WebLogic TX datasource? One thing that I find a little confusing is the notion of transactional behavior in mySQL. I read that it's possible to enable transactions in mySQL-max, however, it's never really been clear to me exactly what I'm supposed to do, or whether I have to do anything. If I'm using a transactional datasource in WebLogic, on top of mySQL, I need to make sure mySQL supports that transactional behavior. Is there a section of the mySQL documentation, or some other documentation, which explains these issues clearly? -- === David M.

Speed issue
Hi
I am trying to move an Access 2000 database into MYSQL 3.27.47nt running on
a Win2K machine. MYODBC with the 3.51 drivers is also installed.
MYSQL is running and readily responds to SQL queries using the DOS window at
the mysql prompt. However, when linking the MYSQL database with ADO and VB6
the response is slow and there is a lot of disk activity before an answer is
returned. It is a lot slower than the original Access2000/VB6 setup.
A DSN-less code is being used to link VB6/ADO to MYSQL. The connection
string is listed below:
con.ConnectionString = DRIVER={MySQL ODBC 3.51 Driver}; _
SERVER=localhost; _
DATABASE=GIS; _
UID=Admin;PWD=africa; OPTION=16386
If of any relevance, within the WinMySQLAdmin on the Environment Tab, MYODBC
is stated as not found eventhough it has been loaded.
Any pointers on how to get rid of the disk churning and get a normal
response in this set up would be much appreciated.
Thanks
Simon

Re: fulltext searching
hi all...
i can't seem to get the fulltext searching working perfectly... single search terms it
works fine, multiple search terms it also seems to be ok - finding records with any of
the search terms.
however, if i try the boolean mode it gives out garbage all the time. i try for
example an sql query like this:
select * from mytable where match(file_text) against('+findthis +andthis -notthis' in
boolean mode);
various variants of this never find the records, or find ALL the records in the
database... when such filters should throw out a couple of records at least.
i'm running mysql 4.0.1-alpha on freebsd... and i've set up the tables for fulltext
indexes.
is this still heavy work-in-progress or should it work? does it work for anyone?

RE: SQL - Fulltext search
hmm, but still sticking to that you'll have to specify a new WHERE argument for each thing you want to test on. Isn't there maybe some way to do it like this WHERE skill IN (regexp(powerpoint, php)) I know this thing won't work, becuase I don't know if you can do regular expressions on WHERE ... IN thingies. But, such a thing would be very handy ... even more when MySQL intruduces the subselect in WHERE .. IN thingies. Some other question, why us using REGEXP in this case better than LIKE ? is it faster, more efficient, something with case-sensitivity maybe?

Strange behaviour of mysqld after adding/dropping a column
Description: The ALTER TABLE command behaves very strange when stopping and restarting the MySQL server afterwards. I noticed this after having rebooted my PC (which means that the MySql server is stopped and restarted). Before the reboot I dropped a column in one of my tables. After I had done this all the data was available in mytable. However after have been rebooting my PC all the data was gone !!! It even becomes crazier. After the second reboot the data was visisble again. The tests I have executed showed that this problem shows up for both adding and deleting a column of a table. Also I noticed that when you add data after have been stopping the MySQL server the first time this data is dissapeared after a second stop of the MySQL server. How-To-Repeat: mysql create database findBug; mysql use findBug mysql create table metatable(objid BIGINT not null, tablename varchar(64), field varchar(64), type varchar(50), PRIMARY KEY (objid)) type=BDB; mysql create table metaindex(objid BIGINT not null, indexname varchar(64), ref_metatable DOUBLE not null, PRIMARY KEY (objid)) type=BDB; mysql create table metaoid(objid BIGINT not null, tablename varchar(64), oid BIGINT not null, PRIMARY KEY (objid), UNIQUE(tablename)) type=BDB; mysql insert into metaoid values(1, metaoid,4); mysql insert into metaoid values(2, metatable,1); mysql insert into metaoid values(3, metaindex,1); mysql select * from metaoid; +---+---+-+ | objid | tablename | oid | +---+---+-+ | 1 | metaoid| 4 | | 2 | metatable | 1 | | 3 | metaindex | 1 | +---+---+-+ mysql alter table metaoid add column test varchar(255); mysql select * from metaoid; +---+---+-+--+ | objid | tablename | oid | test | +---+---+-+--+ | 1 | metaoid | 4 | NULL | | 2 | metatable | 1 | NULL | | 3 | metaindex | 1 | NULL | +---+---+-+--+ mysql quit; C:\net stop mysql C:\net start mysql mysql select * from metaoid; Empty set (0.01 sec) mysql quit; C:\net stop mysql C:\net start mysql mysql select * from metaoid; +---+---+-+--+ | objid | tablename | oid | test | +---+---+-+--+ | 1 | metaoid | 4 | NULL | | 2 | metatable | 1 | NULL | | 3 | metaindex | 1 | NULL | +---+---+-+--+ mysql alter table metaoid drop column test; mysql quit; C:\net stop mysql C:\net start mysql mysql select * from metaoid; Empty set (0.01 sec) mysql insert into metaoid values (5,test,1); mysql select * from metaoid; +---+---+-+ | objid | tablename | oid | +---+---+-+ | 5 | test | 1 | +---+---+-+ mysql quit; C:\net stop mysql C:\net start mysql mysql select * from metaoid; +---+---+-+ | objid | tablename | oid | +---+---+-+ | 1 | metaoid | 4 | | 2 | metatable | 1 | | 3 | metaindex | 1 | +---+---+-+ Fix: Restarting the server twice after have dropped/added a column is the only solution I have found for this problem.

See mysql-test/t/fulltext.test file to see that it does work.
So, you probably, found a bug.

blob versus file
Hi there, I am wondering if anybody has experiance in saving images to blob in mysql. I do save images with 1 K and 4 KB to blob fields while I used to save them to file. It seams to me that this is much slower accessing the files. The images take a bit (really short but absolutly noticable) to show up on the site. Is there a way to improve the performance, and why is this happening? I thought the performance might even boost after storing them to blobs. Thank you for any comments on that, Andy PS: I was planing to store all the other images (20 - 50 KB) to blobs as well (thousands) but after this first experiance I am a bit confused if the performance would even more suffer.

Hi! You can put this into /etc/my.cnf: [mysqld] user=root This will allow to run mysqld as root. However, consider running it under another account, it is safer.

Re: need your attn: can mysql support japanese and korean simultaneouslyin same database
Hi! Joel is right. You can store both, however in 3.23.x and 4.0.x mysqld can use rules of the only one charset for things like GROUP BY, ORDER BY, DISTINCT, etc. In upcoming 4.1, it's possible to have fields of different charsets at the same table. So, japanese and korean sorting will be possible even without Unicode, one needs just to create two fields: in korean and japanese charsets. All operartion with korean field will use korean collation rules. Correspindingly, all operation with japanese field will use japanese collation rules. Joel Rees wrote: i am working on a project in which db is mysql and it should support japanese and korean simultaneously I have mysql 3.23.36 running on red_hat_linux_7.1_sea-wolf and default ecoding for mysql is sjis Kindly tell meif is it possible to make a database support japanese and korean both languages simultaneously I don't really know much, but from what I understand, the answer to your question is probably not. If you want to sort and collate both at the same time, in the same tables, you'll need the Unicode support that is scheduled for ver. 4.1. You can store both at the same time. (You may have some problems with the drivers, but it appears that those problems can be fixed or worked around.) You can also search, if you don't care about missing a few sometimes, or if you can write a little external code to pick up some oddball cases. Or, you might consider keeping the Japanese and Korean data in separate tables on separate servers.

MySQL and ADO:Bug?
Hi, I have been trying for 4 days but I can't solve this problem and I
don't know why.
It's a bug?
I have a table (children) which has a field called borough; I have to
extract the sum of the children of each borough so I use this simple
query:
select count(*) , borough from children group by borough order by
borough
that works.
If I try to call this query from a VB6 project it doesn't work, that is,
it returns an empty recordset.
This is the code that I'm using
Dim rec As ADODB.Recordset
Dim cnn As ADODB.Connection
Dim cmd As ADODB.Command
Dim GlConnString as String
Dim strSQL As String
Set rec = New ADODB.Recordset
Set cnn = New ADODB.Connection
Set cmd = New ADODB.Command
strSQL = select count(*) , borough from children group by borough order
by borough
GlConnString =
server=localhost;db=MyDB;driver={MySQL};uid=root;pwd=MyPwd;OPTION=35
cnn.CursorLocation = adUseClient
cnn.ConnectionString = GlConnString
cnn.Open
cmd.CommandType = adCmdText
cmd.CommandText = STRsql
Set cmd.ActiveConnection = cnn
Set rec = cmd.Execute
---at this point I have an empty recordset
If I try with this query
select borough from children group by borough order by borough
that is, removing count(*) works!
I'm using
Windows 2000
MySQL 3.23.49
MyODBC 2.50.39
ADO 2.52.6019.1
Help me, please!
Thanks
Teo

RE: Speed issue
Simon,
Several issues come to mind.
First, as Tim suggested, make sure ODBC logging is turned off. It should be
by default but if you turn it on, it will whip your HD like a bad puppy.
Second, run MySQL on a different machine. More importantly, understand the
difference between Access and MySQL (If you do already then skip this
chapter)
MySQL is a database server. Access is a desktop database. It takes more
horses to run MySQL than Access because it does more. If all you need is a
single user database running on your desktop (Keep your recipes, checkbook,
etc.) Then Access is an adequate tool. (I prefer Visual FoxPro for these
tasks, but that's just me)
If however, you are developing any sort of multi-user application then you'd
be a fool to use Access. Like FoxPro and dBase before it, it just was not
designed to run like that. Yes, it has been patched and kludged to death to
make it seem like this works but when you get right down to it, it just
can't do the job. So you turn to a database server.
In walks MySQL. MySQL will not allow you to pain forms and reports. It is
first and foremost a database engine with EVERYTHING else left for a client
to do. It will allow you to safely store and retrieve your data, assign
rights to multiple users, and - if compiled correctly - give you a
transaction safe environment for your work.
So it may seem that on your machine, with both MySQL and Access loaded
together Access runs ever so much faster. However, you are comparing single
use Access to single use MySQL. (also, once mysql starts caching things, it
gets faster. The more you use it, the faster it runs!) Also, once you get
MySQL into it's native environment (server class machine or at least one
where nothing else is going on) it will run like a screaming banshee.
At the risk of pissing off all your windows users out there (Check my
headers, created with Outlook, I use it too) Run MySQL on a *nix box of some
kind. Without the overhead of the graphical interface, which just gets in
the way on a server, you have more horses/RAM to run the important stuff.
In short:
MySQL != Drop in replacement for desktop database

Subject: Speed issue
Hi
I am trying to move an Access 2000 database into MYSQL 3.27.47nt running on
a Win2K machine. MYODBC with the 3.51 drivers is also installed.
MYSQL is running and readily responds to SQL queries using the DOS window at
the mysql prompt. However, when linking the MYSQL database with ADO and VB6
the response is slow and there is a lot of disk activity before an answer is
returned. It is a lot slower than the original Access2000/VB6 setup.
A DSN-less code is being used to link VB6/ADO to MYSQL. The connection
string is listed below:
con.ConnectionString = DRIVER={MySQL ODBC 3.51 Driver}; _
SERVER=localhost; _
DATABASE=GIS; _
UID=Admin;PWD=africa; OPTION=16386
If of any relevance, within the WinMySQLAdmin on the Environment Tab, MYODBC
is stated as not found eventhough it has been loaded.
Any pointers on how to get rid of the disk churning and get a normal
response in this set up would be much appreciated.
Thanks
Simon

RE: Mysql 4.0.2
Unless I've misread your post, this was not so much a feature in .51 as it was a bug. If you have a FK contraint then you should never be able to insert a record into the child table that does not have a matching FK in the parent table. (Null does not mean no matching record.)

SuSE 8 and for that matter all version of SuSE MySQl doesn't run until you use YaST to turn it. That why it's not starting. You can start it your by the following command; /etc/rc.d/mysql start If there is no problem with mysql you should see this mysqld done By going into YaST2/YaST and telling it to start mysql it will start it from boot up. For more help with SuSE and start up daemons feel free to write me ok. This isn't really mysql fault, it the way SuSE control things.

RE: Speed issue
So it may seem that on your machine, with both MySQL and Access loaded together Access runs ever so much faster. However, you are comparing single use Access to single use MySQL. (also, once mysql starts caching things, it gets faster. The more you use it, the faster it runs!) Also, once you get MySQL into it's native environment (server class machine or at least one where nothing else is going on) it will run like a screaming banshee. I'll second that ;) We use MySQL extensively here, and we also use Access for the small stuff. Occasionally we will build an Access database, then link tables to MySQL via the MyODBC driver, then do database stuff as usual with VB6. Same with proof-of-concept or demo stuff that we want to upscale quickly. By the way, if you're going to use VB, I'd strongly suggest setting the dbSQLPassThru option on your queries and such, it will speed things up tremendously. If you don't, VB will bring down the entire table or tables to your desktop, then work on the data locally, a HUGE waste of time and bandwidth. You also don't have to use ADO if you don't want to - I use DAO and with passthru turned on, it works just fine ;) -- Ed Carp, N7EKG http://www.pobox.com/~erc 214/986-5870 Director, Software Development Escapade Server-Side Scripting Engine Development Team Pensacola - Dallas - London - Dresden - Paris http://www.squishedmosquito.com - 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: blob versus file
Andy, File Systems are made to store and retrieve files in an efficient way. You may not expect better performance when you put a database in between. When speed is an issue you should use MySQL to store and retrieve filenames and something like ReiserFS, RAID and good hardware to store images. Thomas Spahni On Mon, 1 Jul 2002, andy wrote: Hi there, I am wondering if anybody has experiance in saving images to blob in mysql. I do save images with 1 K and 4 KB to blob fields while I used to save them to file. It seams to me that this is much slower accessing the files. The images take a bit (really short but absolutly noticable) to show up on the site. Is there a way to improve the performance, and why is this happening? I thought the performance might even boost after storing them to blobs. Thank you for any comments on that, Andy PS: I was planing to store all the other images (20 - 50 KB) to blobs as well (thousands) but after this first experiance I am a bit confused if the performance would even more suffer.

Re: redudancy / high availability
Hi all, I want to setup (on linux systems) a pair of redundant mysql servers, working this way : * one master and one backup * the master handles all the requests, the backup updates its data frequently (and, if possible, CONSISTENTLY) from the master * on failure of the master, the backup comes and handles all the requests, as if it was the master. * when the master server comes back, it updates itself from the backup, and then restarts to work normally I think the slave/master system of MySQL is not sufficient (the master does not updates itself after coming back).

Re:Speed Issue - Thanks
Thanks to all who responded to this posting. The problem was due to ODBC logging turned on. When this was rectified the system flew along like a greyhound! I appreciate the other helpful suggestions given. The reason for moving from Access to MYSQL is that I am moving a GIS application developed on a standalone computer to a network environment. There is a potential of 1.9 m employee records a year to be entered into the database - something that Access cannot handle as I have found out to my cost! The final set up will be a dedicated server (Linux is the aim) with clients linking in. I take on board the issue of bandwidth and using the dbSQLPassThru option. A fellow student put me onto MYSQL, which is proving to be the answer to my database problems, especially with such a supportive user group out there!

Re: Help! MySQL overloading my system
Hi, As a first step I would find out what mysql is doing, Use either 'show processlist' or using mysqladmin 'mysqladmin proc'. Or even better install mytop (cd /usr/ports/databases/mytop; make install; ). This program sorts the output for you. There does seem to be a sometimes bug with mysql that 'may' be related to the thread cache. If you have increased the thread cahce (which is mostly not needed) Try reducing the thread cache to 2, but make sure that it is not just a slow query causing the problem.

RE: MySQL client unusable with large data sets
Hi, -Original Message- From: Dave Harms [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 26, 2002 9:05 AM To: [EMAIL PROTECTED] Subject: MySQL client unusable with large data sets I've been a loyal MySQL fan for a few years now, and use it extensively in web site development. But I've run into a problem now (MyODBC 3.51.03) that is making me reconsider my choice. Most of my database access is local using JDBC, but I have some critical Windows software that relies on MyODBC. On small result sets, no problem. But on large result sets, where MySQL should shine, queries take far too long to complete because MyODBC uses mysql_store_result instead of mysql_use_result. If I change the driver to use mysql_use_result, I run into the Commands out of sync; You can't run this command now error, presumably because there's a new query executing before the first one has been fully fetched. This appears to be a fundamental weakness in the MySQL client library design. The only way MyODBC will be usable to me in the future is if it can retrieve records only as needed by the client, and can do this from multiple tables without closing each query first. Is such a thing possible? If possible, will it happen soon? Thanks. We will be considering this option in the next release, 3.51.04, so that one can enable either cache(mysql_store_result) based or non-cache based(mysql_use_result) resultset handling through the connection flag(OPTION parameter). Actually this implementation was added to 3.51.03 itself, but at the last minute the new code base is removed due to some consistency issues. Currently we suggest you to use option 1+2+2048+ 8192 (only for systems that supports named pipes) in accessing large tables.

Re: er diagramming
I would think the incremental cost of adding support (both forward and reverse engineering) for databases such as MySQL would be minimal for Computer Associates and other's who provide robust ERD apps like ERWin. Perhaps we haven't been vocal enough with mainstream tool companies aboout the need to support open source dbs.

Re: innodb @ windows xp
You need to determine if your MySQL is reading it's directives from my.ini or my.cnf. In the correct one, make sure you have commented out or removed any line that reads skip-innodb. then make sure you have directories set up for the innodb files and that you've edited the paths to point to these directories.

have misunderstood the usage of mysql_real_query? I should make two notes

endianism is (should) not be an issue and I am also trying to insert two

Unsigned Int / Signed Int issue when using MyODBC2.5
G'day, I've got a problem with the ODBC driver for MySQL, in that when I use an SQL select statement on a field of type UNSIGNED INTEGER, the resulting recordset in asp uses SIGNED INTEGER data types, so any data 2^31 is dropped by asp. The offending code is as follows: Set sqlCommand = Server.CreateObject(ADODB.Command) sqlCommand.ActiveConnection = MyDatabase sqlCommand.CommandText = SELECT * FROM SQLTable Where DataDate = StartDate and DataDate = EndDate ORDER BY DataDate Set rs = sqlCommand.Execute The database design: mysql describe SQLTable; +--+--+--+-+-+---+ | Field| Type | Null | Key | Default | Extra | +--+--+--+-+-+---+ | DataDate | int(10) unsigned | YES | | NULL| | | DataIn | int(10) unsigned | YES | | NULL| | | DataOut | int(10) unsigned | YES | | NULL| | | Elapsed | int(10) unsigned | YES | | NULL| | +--+--+--+-+-+---+ 4 rows in set (0.00 sec) Unfortunatly, whenever the data in any of the fields exceeds 2,147,483,648 it is dropped from the resulting recordset. ... And just to throw a spanner in the works, that code works perfactly on our development PC, but not on the production server. Does anyone have any idea why this would be failing, or know a better way to select the code and drop it into a recordset (or array) in asp? Thanks for any help.

Re: mysql query for next unique ID
Does anybody know if there is a function to retrieve the next unique ID number for a record to be made in the future? I believe you can reliably allocate sequence numbers from a sequence table (a table used only to dole out sequence numbers) like this: create table sequence ( seq int not null auto_increment primary key); (depending on intended use, you may need to change the size of the integer type, or use an unsigned type). When you wish to get a sequence number, issue these three queries: #1: insert into sequence values (null); #2: select last_insert_id(); Fetch the single-row result from this and put it in variable $s, which gets substituted into the following query before sending it: #3: delete from sequence where seq = $s; Now use $s as your sequence number to insert into another table. Note that this still works if several clients try this sequence of queries on different connections, WITHOUT transactions and WITHOUT any explicit locking between the queries, but with arbitrary interleaving between queries by different clients. Query #1 establishes the sequence number (implicit locking during that query prevents handing out duplicate numbers). Query #2 fetches it, and since last_insert_id() is connection-specific, nothing another connection does will affect the result. Query #3 cleans up the sequence table. Since only one client was handed the sequence number for this row, only one client will try to delete it. Normally the table will only have entries for clients executing between query #1 and query #3, or clients that bombed between query #1 and query #3 (thus, during a lull in activity, the steady state of the sequence table should be empty).

Load data infile problem
I am trying to import a text file that is tab delimited. I am using the following , but it only returns one line. LOAD DATA INFILE '/Users/martinsc/documents/jillslist.txt' INTO TABLE Customers FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'; Why would it do one line and then stop? MySQL indicates one line affected. The database is not empty and at first I suspected that the import stopped due to the same Customer_ID but that is not the case as the ID's for the first records do not exist in the database as they were deleted records.
