php call to mysql
I know this isn't a PHP mailing list, but maybe someone out there can help.
This is my first mysql/php project, and I can't seem to get this call to
mysql to work. I have other queries working, but it seems as though any
time I try to make a call to one of my auto_increment IDs, either PHP or
MySQL doesn't like the way I am querying it. Below is he part of the PHP
script that is supposed to call the fields from my Cat table in my database.
I am sure there are no problems with authentication to get the table or
problems with which table it is selecting.
?php
$result = mysql_query(select * from $table2);
if ($result){
while ($row = mysql_fetch_array($result))
{
print Cat ID: $row[\Cat_ID\];
print Cat Name: $row[\CatName\];
print Cat Description: $row[\CatDescribe\];
print BDelete?/b;
print input type=checkbox name=\Cat_ID[]\
value=\\.$row[Cat_ID].\\ Yes, delete entry #.$row[\Cat_ID\].\;
print BRBR\n\n;
}
mysql_free_result($result);
}

I also tried the above code, but I escaped out the underscores.
Thanks a lot for your help.

2008 : MySQL client run out of memory
Hello, I have this error (2008 : MySQL client run out of memory) performing a request in a PHP script. However that request works perfectly under phpMyAdmin ! I tried to do a lot of mysql_free_result() in my script (because there are a lot of requests) but I doesn't work and I think It is useless. I looked on the PHP site to see if there's not a bug but I didn't configured my PHP with the --enable-memory-limit option. I have the version 4.0.6 with the mysql built-in support. Note that I first compiled PHP with the external mysql support and I had the same error. What's the problem ? How to find the cause ?

Re: Build problems (+solution) on HPUX 10.20/gcc 2.95
Hi Michael,
Michael Widenius wrote:
Between the different configure attemtns, did you do 'rm config.cache'?
If not, then there is a big change that the old content of
config.cache from the first build could have affected the later
builds.
I got an email from Timothy Smith yesterday suggesting the same. I build
a lot of packages using configure and am aware of the config.cache
(guess how I found *that* out.. :))... no.. I almost automatically rm
config.cache before any configure command...
Any change you could quickly check on your machine if the
recommended configure line from the MySQL manual would work one a
clean MySQL distribution ?
On our HPUX 10.20 machine, we use the following configure line to
build our binaries:
CFLAGS=-DHPUX -I/opt/dce/include -O3 -fpic CXX=gcc CXXFLAGS=-DHPUX
-I/opt/dce/include -felide-constructors -fno-exceptions -fno-rtti -O3 ./configure
--prefix=/usr/local/mysql --with-comment=Official MySQL binary
--with-extra-charsets=complex --with-server-suffix= --with-pthread
--with-named-thread-libs=-ldce --disable-shared
Ok. So I gave it another try. I untarred the source distro into a new
directory and ran the configure command above (only different prefix).
Made absolutely no difference whatsoever: still a gazillion+-1 errors
:). Below I have a snapshot of the kind of errors that fly by my tty

Re: 2008 : MySQL client run out of memory
If it is a memory problem, try for example ini_set(memory_limit, 16M); in your script. Otherwise, it may be a loop that keeps allocating memory until it crahes.

Hi, try to use varchar or varchar binary instead. they work fine in my application for searching '%multibyte%multibyte%' condition even. I have tried that. MySQL match all rows i needed. But i match some row i don't want too.. let me show you an example... The charactor ¤¤ in Big5 chinese is 0xA4 0xA4. The charactor ¤ô is 0xA4 0xF4, ôô is 0xF4 0xF4. To match ôô, we should use %0xF4 0xF4%, which, in result, it match ¤ô¤¤ .. 0xA4 0xF4 0xA4 0xA4 too.. i just don't want this kind of cross-charactor match happend. Hi, I have used Solaris 2.6 (Unicode) and Windows 2000 (UTF8 supports Big5) as OS to run MySQL application. In my experience, I have not changed charset parameter in server startup, database or column. They can store latin1 and big5 properly in-a-mix. Have u tested to insert and select your records with different charsets in MySQL before changing the value of charset? the table i want to create is of mixed charsets, ie: Title VARCHAR(10), --- Latin desc_b5 VARCHAR(10), --- Big5 desc_gb VARCHAR(10), --- GB2312 desc_en VARCHAR(10), --- ASCII desc_(some other charsets...) I am now using a simple BINARY option to make this (seems) possible. INSERT work fine with this. However, _SELECT col_name from tbl_name LIKE '%(somthing)%';_ doesn't work as expected with multi-byted charsets... MySQL try to match across two characters. I don't want to use Unicode in this, as Unicode is not a complete superset of all charset i have to use, there will be some losses when i convect to other charsets.. That's why i am asking here.

I assume that you put your query into phpMyAdmin and that's it. In your script, you will obtain the same result when you do the same, as phpMyAdmin does nothing else than call the usual php functions. Therefore, I assume that you will do some other sort of things in your script, like a huge while loop which eats up memory. It isn't hard to construct such a thing.

Re: Populating mysql db from sql server 7
No. The data has to be moved from MSSQL to MySQL some way, and that will be either an export or a copy. AFAIK, there is no way for the two RDBMS's to communicate directly with each other ... you need some sort of intermediary. And before any data can be moved, the table schema must be created on both servers. For our application, we have a written a translation program that updates/alters our old MSSQL7 table schema to match our current MySQL schema. It then uses an ODBC connection to port the row information from MSSQL to MySQL. Theer are a number of ways to do this ... a search of the list archive will turn up many threads on this topic.

Re: error codes ??
Looks to me like a permissions problem. If you were manipulating the MYSQL files as root or if you copied or moved them, this could happen. Look at the permissions on a working machine and match those on this machine. The permissions need to allow changes, but too permissive permissions will cause MySQL not to work as well.

Re: Not so good transaction support
1. Please explain the above in detail. It depends on the type of table you're using. If you're using a table type that only supports table-level locking, then each transaction is isolated by being suspended until the previous transaction is done. This is slower if you do a lot of longer transactions but quite safe. I think the only difference is functions(COMMIT, ROLLBACK) support. This is true, for some table types -- for others, you'll find things work as you expected -- see InnoDB or that other table type (Gemini :-). -- Michael T.

myisamchk reports tables not closed properly
Description:
I'm new to MySQL, and am porting an application from msql. Apologies
in advance for blatant ignorance on my part.
Apparantly the code that increments the counter on whether
a table has been modified is broken. myisamchk reports that:
myisamchk: warning: 1 clients is using or hasn't closed the
table properly
when I don't think it should. Also, note that the configuration
is somewhat non-standard.
How-To-Repeat:
mysqladmin create foo
echo CREATE TABLE try ( user CHAR(9), message TEXT) \g | mysql foo
echo INSERT INTO try VALUES ('hi', 'sailor') \g | mysql foo
myisamchk /usr/local/storm/MySQL/var/foo/*.MYI
Fix:
Fix 1:
$ mysql foo
mysql flush tables;
mysql quit
Fix 2:
$ mysqladmin shutdown
$ safe_mysqld
All of these are only temporary. After inserting/updating to the
table, the warning from myisamchk reappears.

Optimising my select.
Hi, Thanks for the feedback on my earlier problem. I have come up with a query: SELECT *, count(contact_id) AS theCount FROM eventlog LEFT JOIN contacts ON contacts._id = eventlog.contact_id WHERE TYPE = 'CLICK' AND link_id IN (1,2) GROUP BY contact_id HAVING theCount = 2 Thing is it takes forever to run, I haven't seen it complete yet i just have to keep killing the process. I have read up on optimisation and have added some index's to the eventlog table: contact_id and link_id (contact_id on the contacts table is the PK anyways so thats fine). Any ideas on how to speed this up. (In the process list it says the state is Copying to tmp table for ages). Thanks Carl Chambers

Fwd: Re: Embedding MySQL in an application
I have been told it is possible to embed MySQL in an application such that the user never knows a database is running underneath the app. Where can I find more information about doing this? That's simple - as you write the application, keep the user interface and database totally seperate. It's as easy as writing any application that uses a database, you just have to worry a little more about which information you present to the user. I'm currently writing a database-backed web application (using perl and Template Toolkit) where the user will never have to know about the existence of keys or anything like that. As it happens, the code doesn't *have* to run off a database at all (it's nicely modular) but it's the best way of organising my information. I didn't make myself clear. Of course a user should NEVER see a database key. The design of the software will have a distinctly separate database module. The real point is, that a user can take the product out of shrink rap, install it, run the program and never fiddle one iota with installation of MySQL or even know that MySQL is running on the system. MySQL is entirely embedded within the application. Sure I could write drivers in the database module that did all this with flat-files, but ugh what a horrible thought. The plan is in the future as the product line grows is to eventually tie several products together through a seperate database engine, or have then as stand-alone packages. Microsoft advertises their MSDE (MS Data Engine), which does just this. Sits inside a program and the user never has to do any database adminstration functions--it's completly integrated into the program. Then their is the option for a seemless upgrade to MS SQL Server when more power is needed. At least that's the ad. My experience with MS products suggests that MSDE won't work and then for a mere $(excessive figure here) I can upgrade to SQL Server. I feel like it could be the classic bait and switch ploy on the part of MS. The MySQL folks have told me that this has been done and will be fully supported as part of the next release. Problem is I have to demonstrate it NOW, or I may end up stuck with MSDE since it exists NOW. MySQL is my preferred option and I'd love to stick with it across all platforms the product will be ported to. -- Shawn P.

Subject: Fwd: Re: Embedding MySQL in an application
The real point is, that a user can take the product out of shrink rap,
install it, run the program and never fiddle one iota with installation of
MySQL or even know that MySQL is running on the system.
So what you're essentially talking about is embedding the MySQL *binary* in
an
application? There are a lot of reasons why this is a bad idea - it'll
replicate unnecessarily if more than one application does this, you won't be
able to upgrade MySQL (to, say, fix security holes) without upgrading the
application...
...but I suppose that massively monolithic, repetitive code is the way of
the Windows world...
MySQL is entirely
embedded within the application. Sure I could write drivers in the
database
module that did all this with flat-files, but ugh what a horrible thought.
In perl:
use DBI;
if ( -x /usr/local/mysql/bin/mysql ) {
require DBD::mysql;
} else {
require DBD::CSV;
}
But hey, perl's good like that.
The plan is in the future as the product line grows is to eventually tie
several products together through a seperate database engine, or have then
as
stand-alone packages.
This depends on your target platform. With your talk of Microsoft, I presume
that
you're developing for a Windows platform. The best way to do this, IMHO,
would be
to have the installation program for *your* application check to see if
MySQL is
installed (by poking in the registry?), and download and install it (perhaps
invisibly) if it isn't (or you could include MySQL with the CD of your
application, licensing issues permitting).
If you then want to port to (say) Linux, you could have the program package
have a dependency on MySQL (this seems to work very well in Debian, not sure
about RPM-based distribution) which would do exactly the same - check for
MySQL on install, and install it invisibly if it's not there.
Hope this is of some use,
Alex

Re: Table too large?
Normally the size can be 2G, 4G or more... You can check the maximum table size for a table with the myisamchk -dv table_name or table_file if It doesn't work. You should have run myisamchk or mysqlcheck (whick worked better for me) to check your table.

Large tables
I have 3 tables that have all fieds the same (name, length, indexes...) The only difference is that data is stored by year(1999 in table1999, 2000 in table2000, 2001 in table2001) I don't want to merge them because each contains about 15,000,000 records and the index would'nt fit into memmory... What I would like to do is compare for example august 1999, august 2000 and august 2001. I do it like this: create temporary table tmp select * from table1999 where month(dDate)=8; insert into tmp select * from table2000 where month(dDate)=8; insert into tmp select * from table2001 where month(dDate)=8; select year(dDate), month(dDate), avg(zPrice), sum(zPrice) ... from tmp group by year(dDate), month(dDate); Is there a way to do this without using a temporary table?

Binary transaction log
I've been reapplying transactions to my aforementioned screwed up database. It seems however, that the binary transaction log doesn't quite work properly with user variables (with MySQL 3.23.38). I have this entry from the log: insert into Projects (ParentID, Name, LongDesc) values (@customer, VPN, VPN Work); I remember doing that transaction, and I'd done a SELECT @customer:=ID WHERE ... beforehand. Since that SELECT isn't stored in the binary log (that I can find), the value for @customer is NULL. This just seems like a bug to me (I know what my SELECT was, so I've redone it, but this would be a problem for large-scale restoring). PS.

Re: Embedding MySQL in an application
You need to download the MySQL-4.0 source and compile for
embedded-server. This is a library that you link your programs to.
It is used for small devices, like what we are doing here.
I haven't found any docs on it yet, but the header files give plenty or
explaination.
Hope that helped

Subject: Fwd: Re: Embedding MySQL in an application
The real point is, that a user can take the product out of shrink rap,
install it, run the program and never fiddle one iota with installation of
MySQL or even know that MySQL is running on the system.
So what you're essentially talking about is embedding the MySQL *binary* in
an
application? There are a lot of reasons why this is a bad idea - it'll
replicate unnecessarily if more than one application does this, you won't be
able to upgrade MySQL (to, say, fix security holes) without upgrading the
application...
...but I suppose that massively monolithic, repetitive code is the way of
the Windows world...
MySQL is entirely
embedded within the application. Sure I could write drivers in the
database
module that did all this with flat-files, but ugh what a horrible thought.
In perl:
use DBI;
if ( -x /usr/local/mysql/bin/mysql ) {
require DBD::mysql;
} else {
require DBD::CSV;
}
But hey, perl's good like that.
The plan is in the future as the product line grows is to eventually tie
several products together through a seperate database engine, or have then
as
stand-alone packages.
This depends on your target platform. With your talk of Microsoft, I presume
that
you're developing for a Windows platform. The best way to do this, IMHO,
would be
to have the installation program for *your* application check to see if
MySQL is
installed (by poking in the registry?), and download and install it (perhaps
invisibly) if it isn't (or you could include MySQL with the CD of your
application, licensing issues permitting).
If you then want to port to (say) Linux, you could have the program package
have a dependency on MySQL (this seems to work very well in Debian, not sure
about RPM-based distribution) which would do exactly the same - check for
MySQL on install, and install it invisibly if it's not there.
Hope this is of some use,
Alex

Optimising for 4096MB RAM
Hi there, I am trying to optimise MySQL for use on a machine with: Linux 2.4.7-ac9 (only kernel to work with the disk controller) Dual Pentium III 1000 MHz 4096 MB memory RAID-1 Mirror over two 76GB 7200 RPM UDMA disks Reiserfs partition for MySQL As a reference point, I am running the benchmarking tests to measure the performance. I plan on measuring the performance with our particular queries after this. After reading the section of the manual dealing with performance tuning, I used the following in my.cnf: [mysqld] set-variable = join_buffer=2048M set-variable = key_buffer=2048M set-variable = table_cache=1024 set-variable = max_allowed_packet=16M set-variable = max_connections=200 set-variable = record_buffer=2048M set-variable = sort_buffer=2048M set-variable = tmp_table_size=2048M The problem is that these settings don't seem to have practically any effect on the amount of memory that MySQL uses when running the benchmarking suite - I expected it to chew up large amounts of memory with these settings. MySQL is currently only taking up 25MB of RAM - not the 512MB plus I was expecting. This machine is going to be a dedicated database server for a number of web servers - I expected MySQL to take up about half the memory, and disk caching the other half. I want it to run like a beast posessed :) Does anyone have any real world examples and/or suggestions for how to increase the performance? Any other variables I should be looking at? When the machine is operational, the biggest table I expect to be using has 55 million rows and takes up about 2G disk space (compressed, packed, everything).

Re:InnoDB and table optimization?
Philip, InnoDB does not give an exact number of rows to the query analyzer. A problem is that in a multiversioned database different transactions will see a different number of rows in the table, and a single count of rows cannot be kept. It is an eternal problem in query optimization. Errors in estimates will toggle query plans to another, and some queries will run faster, others slower. The estimation algorithm in InnoDB tends to underestimate the number of rows in big index trees or subtrees. I changed the code now so that it multiplies the estimate by 2 if the tree height is 1. The change is already in the upcoming 3.23.41. I do not know if this change will toggle your query plan. A better solution is to make more dives into the tree to estimate the number of rows. Currently only two dives are made, at the sides of the index tree. This is on my TODO list, but improvement in join optimization will not be that big because errors in other factors are bigger: for example, if the table fits in the buffer pool, a search down the index tree runs in about 10 microseconds, while a search which requires a disk seek takes 10 milliseconds. Another solution is to implement ANALYZE TABLE. A 1000-fold error in query time estimates is very common in SQL databases. The classic trick to guide the query optimizer of SQL is to put a column inside a function. For example, WHERE col1 = 'asadsd' AND col2 = 5; can be changed to WHERE SUBSTRING(col1, 0, 128) = 'asadsd' AND col2 + 0 = 5; Then MySQL cannot use the WHERE condition, and the query plan may toggle. In your case there was an index 'running'. Maybe you can prevent its use this way? Regards, Heikki http://www.innodb.com Copied message: I've got a table with roughly 1 rows that's being joined with several other tables Ten-thousand rows isn't a whole lot, but it makes a difference. With MyISAM, the query is optimized perfectly, exactly how I would expect it to be optimized given our indexing scheme, but when I switch the table type to InnoDB, it shifts the query to a much more inefficient one. Sometimes, given enough database usage, internal numbers must shift around, because it reverts to the old optimization and we gain about 10% free CPU. It appears that it has to do with the table information. While 'SHOW TABLE STATUS' is supposed to give inaccurate data for InnoDB tables concerning things like row count, I would expect the optimizer to still get the correct information. However, the inefficient query searches through all the rows in this 1 row table because it thinks it only has to look through half of them (which, if that were true, *would* yield a more efficient query). Is this a known issue, or is EXPLAIN returning the wrong information? On the rare occasion the query explanation reverts to its old plan, we get a significant reduction in resources, but I can't *make* it shiftback. Here is the query explanation with the 1 row table as a MyISAM table (table p is the 1 row table): +---++--+-+-+--- -- \ +--+-+ | table | type | possible_keys| key | \ key_len | ref | rows | Extra | \ +---++--+-+-+--- -- \ +--+-+ | h | ref| PRIMARY,active | active |\ 4 | const | 20 | Using temporary | | p | ref| \ deleted,hid,running,ptid | hid | 4 | h.hid | 378 | where \ used | | pt| eq_ref | PRIMARY | PRIMARY | 4 | p.ptid \ |1 | where used | | pth | eq_ref | PRIMARY | PRIMARY |\ 4 | p.pid |1 | | | sl| eq_ref | PRIMARY \ | PRIMARY | 4 | p.pid |1 | | | pdc | ref\ | PRIMARY | PRIMARY | 4 | p.pid | 13 | Using \ index | | sd| eq_ref | PRIMARY | PRIMARY | 4 | \ pdc.dep_pid |1 | | | plf | eq_ref | PRIMARY \ | PRIMARY | 4 | p.pid |1 | | | ptt | eq_ref \ | PRIMARY | PRIMARY | 4 | p.ptid |1 | \ | | wft | eq_ref | PRIMARY | PRIMARY | 36 | \ pt.logtype,plf.type |1 | | \ +---++--+-+-+--- -- \ +--+-+ Here it is with the 1 row table as an InnoDB table (the only thing that has changed is the table type of p; all other tables are InnoDBtables): +---++--+-+-+--- -- \ +--+-+ | table | type | possible_keys | \ key | key_len | ref | rows | Extra | \
Condensing results, sort of
I was wondering if there's a way to condense results given by a query. What I'm looking at is a situation where the following query will give me a number of rows with all but 1 column the same. I'd like to concatenate that one column (with a user specified string) so that I don't have to break the query up into multiple queries. I also would like to use the limit clause, so, programmatically condensing the results does me no good. SELECT i.incident_id, i.description, r.location, d.name DATE_FORMAT(r.incident_date_time,%m/%d/%Y) AS date FROM incident AS i, report AS r, individual AS d, involved AS v WHERE i.incident_id=r.incident_id AND i.incident_id=v.incident_id AND d.individual_id=v.individual_id ORDER BY r.incident_date_time LIMIT 0,10 Is what I'm looking for possible? (Am I just overlooking something very simple?)

I searched the machine for files with mysql in the path and .cnf in the name (I had to look up how to do that, to give you an idea of my level of experience with UNIX) but found only: ./usr/doc/MySQL-3.23.36/my-huge.cnf ./usr/doc/MySQL-3.23.36/my-large.cnf ./usr/doc/MySQL-3.23.36/my-medium.cnf ./usr/doc/MySQL-3.23.36/my-small.cnf ./usr/share/mysql/my-huge.cnf ./usr/share/mysql/my-large.cnf ./usr/share/mysql/my-medium.cnf ./usr/share/mysql/my-small.cnf which are sample files.

Re: Optimising for 4096MB RAM
You might want to look into what your ulimit settings are for the process starting mysql... usually this can be done with 'ulimit -a' but check your shells man page for more info. You could have a memory limit set for the process and mysql is not able to use the amount of memory you specify. Keep in mind that mysql doesnt actually allocate all the memory you let it until it needs it, so utilities like 'top' wont show the full amount of memory mysql will use until its been up for a while and sufficiently 'used'. Also, your computer has 4096MB or ram, you shouldnt let mysql use absolutly all of it you should keep some of the OS + the other stuff that runs on the computer (if any). ryan - Original Message - From: Corin Hartland-Swann [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 09, 2001 1:41 PM Subject: Optimising for 4096MB RAM Hi there, I am trying to optimise MySQL for use on a machine with: Linux 2.4.7-ac9 (only kernel to work with the disk controller) Dual Pentium III 1000 MHz 4096 MB memory RAID-1 Mirror over two 76GB 7200 RPM UDMA disks Reiserfs partition for MySQL As a reference point, I am running the benchmarking tests to measure the performance.

connecting by knowing someone's scrambled password?

See the descriptions of the PASSWORD() and ENCRYPT() functions in section 6.4.12 Miscellaneous Functions. Note that even if the password is stored 'scrambled', and knowing your 'scrambled' password is enough to be able to connect to the MySQL server! How is that possible? Even if you do know someone's scrambled password, when you connect to the MySQL server pretending to be that user, it will ask you for their non-scrambled password. After you type it in, the server will scramble it and check that the scrambled value matches the scrambled value stored in the database -- but you can't intercept that part of the process and insert the known scrambled password to be checked. -Bennett [EMAIL PROTECTED] http://www.peacefire.org (425) 649 9024 - 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?

About installing MySQL on Linux 7.1
Excuse Me, I'm a starter to Linux. I've downloaded the MySQL-3.23.40-1 for my Linux OS. They are in .rpm form. How can I install the software properly on Linux? I try to follow the instructions mentioned in manual.txt but it didn't work. Can you help me and tell my how to install it via RPM? Thanks! Please send me the solution. E-mail : [EMAIL PROTECTED]
root/bhaselto same pwd, but mysql thinks one is blank
I gave the same password to user root and user bhaselto, using the
statements:
UPDATE user SET Password=PASSWORD('') WHERE user='root';
UPDATE user SET Password=PASSWORD('') WHERE user='bhaselto';
(using the real password instead of '', of course). The 'user'
table shows them as having the same scrambled password:
mysql select Host, User, Password from user;
+---+--+--+
| Host | User | Password |
+---+--+--+
| localhost | root | |
| localhost.localdomain | root | |
| localhost | | |
| localhost.localdomain | | |
| localhost | bhaselto | |
+---+--+--+
5 rows in set (0.00 sec)
(where '' represents the scrambled password, and is *the
same* in all three places -- I've obfuscated it here even though I still
can't see how you could break into someone's account knowing only the
scrambled password, since it's non-reversible).
However, only user root appears to have a non-blank password. If I try
mysql -u root from the command line, I can't log in, and instead I have
to enter mysql -u root -p and then type the '' password when
prompted. This is expected. But when I try to log in as bhaselto, I can
type
mysql -u bhaselto
and log right in with no password. If I type mysql -u bhaselto -p and
then get prompted for a password, I have to hit Enter (submitting a blank
password) to log in. I tried stopping and starting the mysql service but
it didn't help. Why does mysql not ask for a password for user bhaselto?
Related question: if I try accessing the database using the DBI perl
module, then:
my $dbh = DBI-connect(DBI:mysql:database=menagerie;host=localhost,
'root', # username
'', # password
{'RaiseError' = 1 }
);
connects *succesfully*. However, this code:
my $dbh = DBI-connect(DBI:mysql:database=menagerie;host=localhost,
'bhaselto', # username
'', # password
{'RaiseError' = 1 }
);
fails with the error:
DBI-connect(database=menagerie;host=localhost) failed: Access denied for
user: 'bhaselto@localhost' (Using password: YES) at dbdtest.pl line 5
And this code:
my $dbh = DBI-connect(DBI:mysql:database=menagerie;host=localhost,
'bhaselto', # username
'', # password
{'RaiseError' = 1 }
);
(i.e. using a blank password for user bhaselto) fails with the error:
DBI-connect(database=menagerie;host=localhost) failed: Access denied for
user: '@localhost' to database 'menagerie' at dbdtest.pl line 5
So, if the password for user bhaselto really is blank, why didn't the
second example work? And, for that matter, in the second example, it was
the *password* that was blank, not the *username* -- so why did the error
message refer to user: '@localhost'? It seems like it should have
referred to user: 'bhaselto@localhost' since I did give the username as
bhaselto.
Thanks very much to anyone who can help me sort this out! :)

Re: ACT Conversion
Kat: This can be a little tricky ... the version of ACT! you have is pretty old. ACT! is ... TTBOMK ... based on FoxPro. Unfortunately, it doesn't support ODBC, so it doesn't connect to other DB servers. The only way I have been able to port the data from ACT! is to use the built-in export data function, and squirt the data out to a delimited text file. You can import that file into MySQL, but you'll have to create the database schema first. Good luck!

innobase .39b problems
After succesfully upgrading to .39b things seemed to be running

and also:
SELECT * FROM users WHERE username = LOWER('xxx') AND password =

In both cases the connection is using auto commit = 1... so I dont think it
can be a deadlock problem. I am fairly certain that inserts have not been
done to either table in a while (a while being a day or so). Below are the
create table definitions just in case you need to take a look at them. Do
you have any idea what could be causing this? Under the non-large blob
support innobase code this worked without any problems. The only thing that
has changed since then is the upgrade to .39b code and a little bit more
data inserted into the table.

Can someone point me in the right direction of converting a ACT2 DB to MySQL. If it's any help, I recently used the following method to successfully convert an ACT2 database into MySQL: (i) open the ACT data file [your_database].dbf using MS Excel (ii) manually clean up the data in the spreadsheet, eliminating unnecessary columns, values, etc. (iii) save the spreadsheet as a tab delimited text file (iv) create tables in MySQL with appropriate column types for the data to be stored in them (v) load the text file into the tables using the mysqlimport utility Best of luck!

Hi,
I cannot offer a solution but I am having the same problem.
I compiled mysql with debugging and traced it with gdb,
here's the offending code in ha_gemini.cc in the
gemini_init function.
fn_format(pmsgsfile, GEM_MSGS_FILE, language, .db, 2 | 4);
rc = dsmContextSetString(pfirstContext, DSM_TAGDB_MSGS_FILE,
strlen(pmsgsfile), (TEXT *)pmsgsfile);
if( rc != 0 )
{
gemini_msg(pfirstContext, MSGS_DIR tag failed %l, rc);
goto badret;
}
If gemini_init fails, mysqld sets gemini to disabled. It
seems to do this if any table type fails on initialization.
Now what this piece of code is trying to do I have no idea.

programmatically getting field list from a table

RE: connecting by knowing someone's scrambled password?
How is that possible? Even if you do know someone's scrambled password, when you connect to the MySQL server pretending to be that user, it will ask you for their non-scrambled password. After you type it in, the server will scramble it and check that the scrambled value matches the scrambled value stored in the database -- but you can't intercept that part of the process and insert the known scrambled password to be checked. It's called bruteforcing... knowing the scrambled password, you can encrypt every possible password and compare it to the scrambled password to find the original password. Either that or the scrambled password is encrypted by the client then sent for comparison, but I doubt it. - 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?

http://www.mysql.com/doc/U/s/User_names.html says: MySQL encrypts passwords using a different algorithm than the one used during the Unix login process. See the descriptions of the PASSWORD() and ENCRYPT() functions in section 6.4.12 Miscellaneous Functions.

Even if you do know someone's scrambled password, when you connect to the MySQL server pretending to be that user, it will ask you for their non-scrambled password. After you type it in, the server will scramble it and check that the scrambled value matches the scrambled value stored in the database -- but you can't intercept that part of the process and insert the known scrambled password to be checked. -Bennett The manual certainly *does* need a clean-up on this. --- 4.3.6 Setting Up Passwords: ...When the user jeffrey attempts to connect to the server using this password, the mysql client encrypts it with PASSWORD() and sends the result to the server. The server compares the value in the user table... --- Which would explain why knowing the encrypted password is enough to gain access to the server (you would, of course, need to write your own version of the mysql where you skip the PASSWORD call). However, --- 4.2.8 Access Control, Stage 1: Connection Verification ...The encrypted password is then used when the client/server is checking if the password is correct (This is done without the encrypted password ever traveling over the connection.) ... --- These two statements surely contradict each other. / Carsten -- Carsten H.
