Re: Innodb tables lose foreign keys after creating an index...
Rick, sorry, it is not mentioned in the manual that MySQL performs a CREATE INDEX by doing an ALTER TABLE. And ALTER TABLE has the feature (= documented bug) that it removes foreign key definitions. You should define all your indexes within the table create statement, like in: CREATE TABLE parent(id INT NOT NULL, PRIMARY KEY (id)) TYPE=INNODB; CREATE TABLE child(id INT, parent_id INT, INDEX par_ind (parent_id), FOREIGN KEY (parent_id) REFERENCES parent(id)) TYPE=INNODB; Best regards, Heikki Tuuri Innobase Oy --- Order technical MySQL/InnoDB support at https://order.mysql.com/ See http://www.innodb.com for the online manual and latest news on InnoDB -Original Message- From: Rick Flower [EMAIL PROTECTED] To: MySQL Mailing List [EMAIL PROTECTED] Cc: Heikki Tuuri [EMAIL PROTECTED] Date: Friday, March 01, 2002 2:32 AM Subject: Innodb tables lose foreign keys after creating an index... Hi all.. Are any of you aware of a way to get indexes to work at all with Innodb tables containing foreign keys? I'm finding that after doing a create index on a table which *had* foreign keys, after the create, the foreign keys are gone.. I've included a simple test below which shows off the problem quite well.. I've searched around on Google to see if anyone had run into this problem, but didn't find any reference.. This really makes foreign keys worthless in MySQL.. The more I dig into MySQL, the less I like it due to missing features or wierd side effects of existing ones.. Perhaps someone can shed some light on what I may be doing wrong.. By the way, I'm using MySQL 3.23.47 on a Solaris box -- if it matters.. To reproduce the problem: 1) create table test_fk_parent(id int not null, primary key (id)) type=innodb; 2) create table test_fk_child ( id int not null unique, parent_id int, index par_ind(parent_id), foreign key(parent_id) references test_fk_parent(id)) type=innodb; 3) create index CHILD_KEY on test_fk_child (id); Below is the sample output : mysql create table test_fk_parent(id int not null, primary key (id)) type=innodb; Query OK, 0 rows affected (0.04 sec) mysql create table test_fk_child ( id int not null unique, parent_id int, index par_ind(parent_id), foreign key(parent_id) references test_fk_parent(id)) type=innodb; Query OK, 0 rows affected (0.05 sec) mysql show table status; ++++--++--- --+-+--+---++-- ---+-+++--- --+ | Name | Type | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Create_options | Comment | ++++--++--- --+-+--+---++-- ---+-+++--- --+ | test_fk_child | InnoDB | Fixed |0 | 0 | 16384 |NULL |32768 | 0 | NULL | NULL | NULL| NULL || InnoDB free: 5807104 kB; (parent_id) REFER vista/test_fk_parent(id) | | test_fk_parent | InnoDB | Fixed |0 | 0 | 16384 |NULL |0 | 0 | NULL | NULL | NULL| NULL || InnoDB free: 5807104 kB | ++++--++--- --+-+--+---++-- ---+-+++--- --+ 2 rows in set (0.01 sec) [[[ NOTICE THE EXISTING FOREIGN KEY ABOVE ]]] mysql create index CHILD_KEY on test_fk_child (id); Query OK, 0 rows affected (0.21 sec) Records: 0 Duplicates: 0 Warnings: 0 mysql show table status; ++++--++--- --+-+--+---++-- ---+-+++-+ | Name | Type | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Create_options | Comment | ++++--++--- --+-+--+---++-- ---+-+++-+ | test_fk_child | InnoDB | Fixed |0 | 0 | 16384 |NULL |49152 | 0 | NULL | NULL | NULL| NULL || InnoDB free: 5807104 kB | | test_fk_parent | InnoDB | Fixed |

Re: odbc...
Is it possible to have global access to all databases using the new odbc driver? For example I have an app that uses more than one table owner. In Mysql, I had to set up a db for each owner but when I try to connect through the odbc, I don't have access to all the databases, just one. How can I get access to them all? As far as I know Delphi provides such issue that can connect to DB selected in Object Pascal not in ODBC driver. ODBC describes the the name and port of server only.

buggy round()
Hi, there are a couple of bugs related to the round() function. (See the thread 'Can somebody help me with round (columna,columnb) ?') One bug is already well known and documentet, it is related to different C library implementations on different platforms: the result of round(2.55,1) may be 2.5 or 2.6. The other bug is related to using a column name as the decimal parameter to the round() function (select round(col1,col2) from table). The rounding is performed, but the result is padded with zeroes, so that all rows have the same number of decimals. The number of decimals used is the number of decimals in the definition of col1, or if 'col1' is an expression, the highest number of decimals in any of the parameters in the expression. This is wrong, because 1.1000 indicates a higher grade of precision than 1.1, even if it has the same numeric value.

PHP and MySQL for a Collaboration project
Hello All, I have been lurking here for the past couple of weeks and learning a bunch, thank you for all of your posts, just listening to you guys is great. We are developing a web based file management interface for collaboration and security. - Login script - Add three levels of security - Admin - Allows editing of files with file locking - User Specific can view some of the files, not all... - Guest - can only view a few files. - Add / Remove users and permissions to view / edit... - Add / Remove files with file description / size and type We are using PHP and MySQL for this, however, I am concerned about the security of some of the more sensitive files. We would like to have them simply in an HTACCESS protected folder, however, we want to use PHP to add and remove the users through a web interface, we don't want people to just be able to type in the URL of the file and get it again, for two reasons, 1. General Privacy 2. Maybe someone has it checked out and editing it. I have read the post about containing images within a MySQL database. Should we store the files inside the DB, using the posted method of storing an image, and relying on MySQL inherent security, the HTACCESS method or does anyone have a better suggestion?

RE: Access denied for user: (from perl script)
Are you using the latest version of DBI? Also, your if ($dbh) { seems a
little backward. According to the DBI docs, If the connect fails (see
below) it returns undef and sets $DBI::err and $DBI::errstr. So shouldn't
your conditional be if (!$dbh) {. Perhaps you are actually connecting.
I'm not sure why DBI::errstr would be defined in that case though. Also, I
hope that is not your real connection info (i.e. username, password,
hostname, database name). If it is, you should change it immediately.

I have heard this was done to get Darwin's version number closer to the version of OS X that it ships with and will at some point in time become the same version number as Mac OS X to make things more uniform. In any case, you can use the Software Updater to update to OS X 10.1.3 which will also update Darwin to 5.3. -- David Steinbrunner mailto:[EMAIL PROTECTED] MFM Communication Software, Inc. http://www.mfm.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: creating dream tables

Also, I'm using an HTML form user to input id and select the year so there shouldn't be any problems with wrong years. I added the sum(hours) as 'totals' to get row totals for all hours per month but so far I'm using a second query to get the grand total hours. mysql SELECT SUM ( hours ) AS 'g_total' FROM log WHERE id='$id' AND YEAR ( period ) = '$sy' AND YEAR ( period ) '$ey'; Now, if you know a way that MySQL can extract the grand total from the first query I'll be able to do in one query what I originally thought I'd have to do in no less than 14!

AA Can anyone please advise how i could go abt it and what are the things i AA should look out for? AA Can i just install myODBC and export Access database to mySQL? Not sure how AA to do that too... Three days ago Steve Rapaport posted a good instruction about porting MS Access database to MySQL. Here is an edited quote of a message from Steve comes: Basically the easiest way is to export the Access database using export from the file menu, in a CSV format with quotation marks around strings. Caution 1: You will need to remove or escape any newlines in your Access database. For some stupid reason Access allows them in the fields, but has no way to search or replace on them! Caution 2: Use Tab instead of comma as a field separator. Then, in Mysql, make a new database.You will need to manually create the same scheme for each table (this is necessary because there is no way to guess or export the Access scheme, that I know) Indicate the type and size of each field in each table. ORDER IS IMPORTANT. If you get the fields in a different order, this will NOT WORK. Last, on the machine running mysql, change directory to the directory containing the export files, which you may wish to name table1.sql, table2.sql, etc. Use mysqlimport to put them into the database.

I know I can symlink from the mysql database directory to the directory in the users home dir, but then mysql needs r/w access to the db directory files and I need to know the best way of doing this without compromising security, so that one user can't get into another users directory, etc. Thanks, Paul - 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?

Error creating InnoDB table/MySQL parser bug?
Hello, Today, I compiled MySQL (mysql-3.23.49.tar.gz) on a Debian Potato system. I configure'd with following options: ./configure --prefix=/usr/local/mysql --with-innodb make and make install ran without any problems. Then I followed the instructions in the INSTALL-SOURCE file. Everything worked fine. Then, I tried to create a InnoDB-Table in the test database: shell /usr/local/mysql/bin/mysql -u root -p mysql use test mysql create table workorders (wo_no varchar(12) not null, foreign_log_no varchar(12) not null default '', primary key(wo_no)) type=innodb; Table creation didn't succeed and I've an error message: ERROR 1005: Can't create table './test/workorders.frm' (errno: 150) After checking my statement and trying to create other InnoDB tables (which succeeded!) I tried: mysql create table workorders (wo_no varchar(12) not null, foreig_log_no varchar(12) not null default '', primary key(wo_no)) type=innodb; Here is what I've got: Query OK, 0 rows affected (0.00 sec) The only different thing is that I changed foreign_log_no to foreig_log_no. It seems that the MySQL parser got irritated when I tried to use foreign as a beginning of a column name.

Emulating a sequence in MySQL?
I need to have unique id's for every data element in my system no matter which table it's in. In Oracle I can create a sequence and with one SQL query I can increment the value and retrieve it for use in my next insert. Can I do this in MySQL? I know about AUTO INCREMENT but that appears to only work on a per table basis. Another key requirement is being able to increment the value and retrieve it with one SQL call. I'm thinking that I can create a table with one column to represent my sequence. The question I have is can I increment the value and retrieve it with one SQL statement? This may sound like a strange set of requirements but we're trying to get our app (a Java JDBC thing) to work across Oracle and MySQL without code changes.

Re: replication issue (A _REAL_ ISSUE)
I was wrong. My slave servers are STILL 'hanging' and not continuing to replicate. They give no errors, the slave appears to stay running, it just lags behind the master. Nothing I have done has fixed this. Again I'm running 3.23.49. To fix the problem I issue a slave stop, slave start command. This appears to kickstart the slave process and it catches back up to the master. Thoughts? On Wed, Feb 27, 2002 at 01:29:31PM -0600, Michael Douglass said: It would appear that the apparent lagging/slave processes not working (yet telling me they are up) was due to having two slaves set to the same server-id. I will know as more time passes. On Wed, Feb 27, 2002 at 09:27:04AM -0600, Michael Douglass said: David, I am seeing the exact same thing on some Solaris boxen. My database sees a couple of updates every minute or two; and show slave status on the slave always appears to lag behind the master. The data in my tables lag as well as I've done some rudimentary checksumming and have found differences. I've found that if I go to each slave and do a slave stop and a slave start that it restarts the slave connection and then runs through all of the new changes. Mysql community, Thoughts as to what could be causing this? I am using --replicate-do- db command to replicate only a single database; that's about the only thing I can think of that is special about my setup. Thanks, On Mon, Feb 11, 2002 at 10:24:46AM -0800, David Piasecki said: I've recently set up replication on one of my databases. Both master and slave are running MySQL 3.23.46 on FreeBSD 4.1. The only tables that get updated or inserted into hold approximately 140,000 records, growing at a rate of around 50-100 every day. The issue is it is currently taking approximately 20-30 minutes for an update/insert that occurs on the master to show up on the slave. An insert operation on the master usually only takes a second or so, so it doesn't make sense that it should take so long for the slave to update. There is nothing non-standard about either table - each contains approximately 20 columns, one auto-increment field, and one index. Hoping someone has some insight into this matter... BTW, both servers are on the same private network, literally being right next to each other, so I know it's not a network issue.

Only when I executed a query, I did not realize that instead of deleting two users I deleted all users... And guess what, after that I flushed the privileges and exit mysql (I had no idea what I had just done). Later on I realized I can not connect to the server anymore, and then is when I realized what I had done. My question is: is there any way to connect to mysql server if there is no user in the user table?? Than you all, P.S.

High Memory Problem
Hi all, I have a seperate linux server with just mysql running on it. But there are alot of other things that I may need to take off. Anyway yesterday I noticed after running TOP that the memory usage was real high. I did a shutdown and checked it after the reboot and the memory usage was way down. Is there something I am doing wrong in mysql that would create such a high memory useage. Or should I be looking at the red hat list to see if it is something else.

help me with complicate sql query
Hello sql guru's, I need help find SQL to solve a problem: I have two tables, the first is persons: person_id int unsigned not null auto_increment firstname varchar(25) lastname varchar(25) The second is person_orgs person_id int unsigned not null org_id int unsigned not null A person may be assigned more than one org by using person_orgs table, but they can only be assigned to an org one time by way of application rules/logic. Here is my problem: I need to select a list of persons that have not ever been assigned to an org OR have not been assigned to a specific org, such as org_id = 1, so I tried: select p.firstname,p.lastname from persons p left join person_orgs po on p.person_id = po.person_id where(po.org_id 1 OR po.og_id IS NULL) I thought this was correct, and it does return persons never assigned before, but all it does concerning the specific org_id is to leave out the one record where the person is assigned to org_id = 1. If the person is assigned to org_id =1 plus any additional, then the record for the other org(s) is/are returned, giving me a person I don't need. I have no idea how to do this. It is almost as if I need to transform: person_id org_id 1 1 1 2 1 3 into: person_id org1org2org3 11 2 3 but I don't really know how in sql, and the number of orgs will be different for each person. I know I could build some large associative array in my language of choice and sort through it somehow, that just seems slow and cumbersome. I feel there is some SQL based solution, I just can't grasp it. Can anyone else?

Re-baselining replication slaves?
I started replicating the MySQL DB on our production server last month. I was wondering if anyone who has been doing replication for a while has seen the need to resync the slave. (i.e. snapshot the master, install on slave, and re-start replication from snapshot) Are there systems out there that have been replicating for a year plus with no troubles?

(See the thread 'Can somebody help me with round (columna,columnb) ?') One bug is already well known and documentet, it is related to different C library implementations on different platforms: the result of round(2.55,1) may be 2.5 or 2.6. I would argue whether that is a bug... it is inconsistent on different platforms, but it is consistent with the behaviour of other programs on the same platform. You always break the one or the other thing. Since there is another way to get consistent behaviour across platforms (FLOOR((2.55*10)+0.5)/10), but I know of none to get it consistent with the platform, I prefer the current behaviour.

I would have expected 0/0.5/0.55 or 1/0.6/0.56 Well, if at all, I don't think that this is a new bug, but a reincarnation of the bug above: it's the behaviour of your underlying system lib.

Problem with Images and Blobs
Hello, look I'm trying to insert an Image into a blob field with a Normal insert query. I know that the information that will be contained on the blob field should be between (quotation marks), but if inside the info of the image is a quotation mark it should be escaped with a \ (back slash). I was reading a document for perl that use a special function called addslashes, that add a backslash to the characters , ', NULL and the \, I think the NULL character is the Ascii ( 0 ) so in every file I scan I will add a \ before a Ascii (0). After add a \ before an Ascii(0) mysql still tell me that I have an error on say ( I'm trying to save gif image): 'GIF89a' the Image is GIF89a0x00 - this represent a ascii(0) value, so I add: GIF89a\0x00 but the problem is the same, could somebody tell me how can I do that, or what do I need to modify, thanks in advance.

Suggestions???
I've recently upgraded to the newest version of php and since doing so many of my pages no longer work when it comes to updating, for whatever reason. I simply do not have the time to waste trying to figure out why so I'm thinking of going back to the previous revision I had on the box. I'm running a Dell pre install box and when I called Dell they told me I could simply use the rpm --oldpackage command. Is this a wise choice? Will it cause me bigger headaches? Will things work right if I do that? Please advise as I am pulling my hair out over here. Thanks Your message cannot be posted because it appears to be either spam or simply off topic to our filter.

I have a database that tracks letters to the editor published in my paper. The table includes a date field and a status field. Status can be either input or published. What I want to do is create a report that tells me how many letters were published on each of the last 30 days. Is there a way to construct the query so that only one pass is made at the database, or must I loop through the last 30 days counting how many records have published status and equal date?

-Original Message-
Eddie:
I see your point. I wouldn't get hung up on what MySQL looks like relative to
MSSQL. Use the MSSQL Query Tool for a day and they start to look pretty
identical.
There's really no direct comparison between MSSQL security and MySQL security
interfaces, however. They look different and there's no MMC for MySQL, but the
implementation you're trying to effect actually would look identical in either
if you look at the grant section of the MySQL manual outside the context of the
MMC/MySQL administrative tool you're using.
In MSSQL you can create a user and the applet in MMC lets you assign rights at
that time along with setting global and db/table/right specific things. You can
also go into the Security section (forget what it's called) in MSSQL MMC and do
the same things. In MySQL, the MMC could be one of several that people use
out there, but you can effect the same result. The example given previously
does exactly what it appears you're attempting to accomplish:
GRANT USAGE ON *.* TO test@localhost;
GRANT USAGE ON *.* TO test2@localhost;
GRANT ALL PRIVILEGES ON db.* TO test@localhost
IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON db.* TO test2@localhost
IDENTIFIED BY 'some_pass';
If you have a db named 'Eddie' on your server you won't have tables named
ed.table1 and pe.table2. They'll be named Eddie.table1 and Eddie.table2;
correct. I'd have never thought to put a period in a table name under MSSQL,
which is what appears to have happened on your MSSQL Server per your example.
Standard db naming conventions follow this form: db.table.field.
WRT creating 'tables prefixed by the db name' I'd encourage you to look at it
as:
mysqladmin create Eddie
mysql
mysql USE Eddie;
mysql CREATE TABLE Table1 (tid int);
mysql INSERT INTO Table1 VALUES(1);
mysql SELECT * FROM Table1;
-or-
mysql SELECT * FROM Eddie.Table1;
-or-
mysql USE mysql;
mysql SELECT Eddie.Table1.tid FROM Eddie.Table1;
If your schema uses periods in it's implementation, I'd look at correcting that
before trying to think about it in MySQL terms (or Oracle, Sybase, DB2,
PostreSQL for that matter). But the 4 grant statements above will give you a DB
that 2 users own {have full permissions to except for GRANT}.

Van

RE: Please Help! MySql 4.01/PhP 4.06 looking for Libmysqlclient.so.10?
PHP is looking for the client library that gets installed with MySQL 3.23.4+. Now, you can try a QUICK fix that might not work, but it's worth a shot. Go to the directory that has the libmysqlclient.so.11 file and type the following: ln -s libmysqlclient.so.11 libmysqlclient.so.10 That should create the file libmysqlclient.so.10 that links to ...so.11. If the client library is vastly different, though, it might not work. If it doesn't work, you should go uninstall PHP, go to the directory where everything was being compiled, edit the necessary files to have PHP use libmysqlclient.so.11 instead (this might be in the Makefile - but be sure you run a make clean first), and recompile. I don't know how different the PHP RPM will be, but there should be a place where you can change the reference to libmysqlclient. I use FreeBSD's ports system and it has a special configure script that creates a little addon to the Makefile that specifies the library version numbers like 10 or 11, and you can change that file before compiling. - Jonathan -Original Message- From: Ronald Arenas [mailto:[EMAIL PROTECTED]] Sent: Friday, March 01, 2002 12:19 PM To: Mysql Subject: Please Help!

Re: High Memory Problem
What is the memory being used for? Linux aggressively caches data, so if most of the memory is showing up as 'cached' or 'buffered', then the high memory usage is caused the system's normal response to lots of database and disk activity. It's trying to keep as much data in RAM as possible. This is a good thing. A well-tuned loaded Linux system will frequently have only 10% of memory free at any given time. james montebello On Fri, 1 Mar 2002, Joe Bifano wrote: Hi all, I have a seperate linux server with just mysql running on it.

if statements

Re: MySql 4.01 and libmysqlclient.so.10 - TEMP FIX
Ronald, I ran into exactly the same problem you describe after compiling a new MySQL v4... I think I can offer you an unsophisticated workaround (read: HACK!), but I'd defer to others on the list who know much more about this than I do... Your problem is because your new compile (or binary install) is expecting the layout previously used by mySQL v3. Until you sort this out, the quick fix is to make a link to libmysqlclient.so from where php 'thinks' it is. On SuSE SPARC, these directories work; you should interpret/infer/accommodate as required for your architecture: Create these links: /usr/lib/libmysqlclient.so.10 - /usr/local/lib/mysql/libmysqlclient.so.11 /usr/lib/libmysqlclient.so.11 - /usr/local/lib/mysql/libmysqlclient.so.11 This should make BOTH MySQL and PHP happy, but does not fix the problem with Apache - you may run into - about mod_auth_mysql.

It may be well known and hard to fix, but that does not make the expression right. :) Well, IMHO no, a bug is an unexpected flaw. The imperfection of the float and real types of the according standard were by design and are well-known. It is also well documented in the manual. A kind of deficiency from the end user's view (i.e. not providing a perfect floating type). Okay, but that's just a matter of wording. Since there is another way to get consistent behaviour across platforms (FLOOR((2.55*10)+0.5)/10), but I know of none to get it consistent with the platform, I prefer the current behaviour. This formula is pretty straight forward... why is it so difficult to implement it in the round() function? I know, read on... ;) Hm. Don't know. Did not care until now. The explanation of the ROUND() function explains to take the work-around if consistent behaviour is wished. And I did not asked further until now. Maybe there are other problems which we don't see at the moment. [...] With this inconsistency in mind, is floating point really usefull for anything? I can't think of a project where I would use it... when you have very big and very small values in the same column, and accuracy is not important...? This is not a flame, I really wonder what people use it for! :) Well, float is called an approximate storage type, and therefore I would think that it is usable in all cases, where an approximated value (up to a certain precision) is good enough. More important: this is a trap for novice users, maybe mysql would have been better of without floating point numbers? Keep the decimal/numeric type, but not using floating point as an internal representation, and also not using floating point for decimal constants... just a thought. Think the other way around: If the other option is to have no floating point type at all, a not perfect one may be good enough for many cases. I would think that novices aren't aware of the different issues involved when rounding numbers (you don't want to round 0.5 always only up [or down] in statistical data because that will introduce an systematical error with large data sets) and therefore the slight errors they will get using float are not bigger than those they introduce by ignorance. Also, this problem is explained in detail in the manual: http://www.mysql.com/doc/N/u/Numeric_types.html http://www.mysql.com/doc/P/r/Problems_with_float.html So if someone cares (to read), she will know to rather avoid float if she didn't really understood it. I suppose a replication setup with master/slave on different platforms could also suffer from this... a statement involving floating point operations may give a different result on the slave... I guess this could mean trouble in some applications. Interesting question. Until now I did not think of that (well, neither I am currently using float types), but yes, that could become a problem (replication data is currently transferred as string representation, AFAIK).

Re: FLOATing point bug? Or just a SQL rule
On Friday 01 March 2002 2:51 pm, Thomas LaCicero wrote: I am not sure if this is going to sound like a stupid question but here it goes... If I have a table with a Float field and, an entry in that field that has at least one decimal place, and I try to do a SELECT * FROM some_table WHERE some_float_field = 3.2 the query will return 0 rows even when there is a matching row. Hope I described this well .. I am running the latest 3.23 release (49a I think) Is this a bug in MySQL or does it have something to do with a SQL definition? This is a bug in your understanding of floating point numbers. The basic answer is that you cannot compare two floating point numbers in _ANY_ computer language using =. Check a small delta around the number you are searching for or store the float field as an integer (e.g. 32 in the above). This is related to the reason that you cannot write 1/3 in decimal... the number goes out to infinity. Now, consider binary. - 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: MySql 4.01 and libmysqlclient.so.10 - TEMP FIX
I would not recommend that. I completely messed up my RH 7.2 system when I tried to forced the MySQL install with 4.1. I had to reinstall the system to make it function right. There might have been an easier way to fix all the broken problems that I caused, but I couldn't. I just moved my data and reinstalled. It wasn't worth the time of trying to fix all the problems since an install can be done and have it up and running within 2 hours.

Your problem is because your new compile (or binary install) is expecting the layout previously used by mySQL v3. ... If anyone can offer us more, please do! LP I have installed MySql 3.23.49, PHP 4.06, and Apache 1.3.20 successfully on my RH 7.2 box. Now I try to install MySql 4.01 (after removing MySql 3.23.49) I get a Php-mysql.4.xx requires libmysqlclient.so.10. My attempt to install MySql 4.01 ends there. I did some reading and found that libmysqlclient.so.10 comes with MySql 3.23.xx. I surfed my directories to find that MySql 4.01 installs libmysqlclient.so.11 I installed theses packages using the RH RPM Manager. Am I missing something? - 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?
