Re: how to prevent inserting duplicate rows?
how do I OVERWRITE the previous entry in the table? ie. is there a SQL command to do like INSERT, but if duplicate found, overwrite with the new value.

Got timeout reading communication packets
Hi! I posted this last week, but, haven't seen any replies yet, and, generally, there seems to be a lack of replies in the archives on the Got timeout reading communication packets related issues. Here is the issue again: We have started doing some rather large replace intos and inserts (~3MB) using a client written in C. However, these queries are truncating at around 100k - meaning, it inserts about 100k or so of the blob field.. but, stops and truncates out the rest of the query. There is no error returend by the connection, but, the error log does have errors such as these: 010323 11:15:19 Aborted connection 45 to db: 'unconnected' user: 'root' host: `localhost' (Got timeout reading communication packets) The same occurs if I pipe the query directly to mysql from the command line. No error, but the data field only has about 100k of the data there before it just stops. The table looks like this: # MySQL dump 8.13 # # Host: localhostDatabase: reflectivity # # Server version3.23.35 # # Table structure for table 'measurement_extended_data' # CREATE TABLE measurement_extended_data ( content_typeID tinyint(3) unsigned NOT NULL default '0', contentID int(10) unsigned NOT NULL default '0', arrayID smallint(5) unsigned NOT NULL default '0', positionID mediumint(8) unsigned NOT NULL default '0', testID smallint(5) unsigned NOT NULL default '0', iteration smallint(5) unsigned NOT NULL default '0', test_locationID smallint(5) unsigned NOT NULL default '0', date_added int(10) unsigned NOT NULL default '0', added_by mediumint(8) unsigned NOT NULL default '0', data blob NOT NULL, PRIMARY KEY (content_typeID,contentID,arrayID,positionID,testID,iteration), KEY test_locationID (test_locationID), KEY testID (testID) ) TYPE=MyISAM; Smaller queries work fine. It's just when they seem to be over 1 or 2MB. /etc/my.cnf looks like this: # MySQL Configuration File # # One can use all long options that the program supports. # Run the program with --help to get a list of available options # This will be passed to all mysql clients [client] port= 3306 socket = /tmp/mysql.sock # Here is entries for some specific programs # The following values assume you have at least 32M ram # The MySQL server [mysqld] port= 3306 socket = /tmp/mysql.sock skip-locking set-variable= key_buffer=256M set-variable= max_allowed_packet=7096128 set-variable= thread_stack=128K set-variable= back_log=50 set-variable= max_connections=512 set-variable= tmp_table_size=15M set-variable= table_cache=6000 set-variable= sort_buffer=3584K set-variable= join_buffer=512K set-variable= connect_timeout=2 set-variable= record_buffer=1M set-variable= flush_time=900 set-variable= wait_timeout=300 [mysqldump] quick set-variable= max_allowed_packet=16M [mysql] no-auto-rehash [myisamchk] set-variable= key_buffer=32M set-variable= sort_buffer_size=48M As you can see we bumped up the max_allowed_packet because we were getting server has gone away errors. - Box is a 1Ghz XEON /w Redhat 7.2 and 1GB RAM - MySQL version is: 3.23.35 - Query is a fairly straight forward insert or replace into and is verified as clean.

MYSQLDUMP feature request :)
Hello mysql, Resently MYSQL have introduced transaction support, which at least in INNODB allows to make consistent backup/recovery. The bad thing about this is - MYSQLDUMP does not support anything about this, so I had to done the same things buy hands. The Idea is quite simple - to add transaction start in the begin of backup and in the begining of recovery. This would take a consistent backup of all of the tables, and as well will allow consistent recovery, at least if not using drop table. -- Best regards, Peter mailto:[EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

if i set a field as a primary key, does it automatically make sure its unique or should i declare a UNIQUE constraint as well? or will primary do the job by itself. a primary key is always unique.

Kylix with MySQL
Hi Everybody! I want to develop some database application under RedHat 7, with Kylix using MySql. I'm using MySql 3.23.38. It uses libmysql.10, default limbysql.6. Kylix native MySql driver cannot connect to MySql server on the same (neither localhost, nor IP) but MySql is Accessible from Windows/ODBC via network, and with the MySql Clients. Error: Invalid UserName/PassWord. Does anybody have some information how to solve the problem? I would use the highest MySql Version. I heard somewhere that Kylix supports libmysql.6 only. If that's the problem what is the highest MySql version using that lib. Shall I change the whole MySql installation or the libfile only? I would appreciate some help. regards Akos
[request] IP Address Functions
Hello,
I have a feature request: How about adding a built-in function to convert
IP addresses from strings to INT UNSIGNED, and another function to
convert vice versa.
This makes it easier for e.g. people whose web applications log IP
addresses in MySQL; it is more efficient to store IP addresses as INT
UNSIGNED than VARCHAR(10). Also, mask operations (e.g. '' and '|') can be
performed on INT UNSIGNED.
I have attached two C functions (ip2num to convert from string to unsigned
long, and num2ip to convert from unsigned long to string) that could be
used as code if someone decides to make a built-in function for this.
-Philip Mak ([EMAIL PROTECTED])
/* ip.c
*
* Functions for converting IP addresses between strings and
* unsigned long int.

unsigned long ip2num(char *char_ip) {

sscanf(char_ip, %d.%d.%d.%d, num_ip, num_ip+1, num_ip+2, num_ip+3);

You are possibly not escaping binary fields.

Re: $sth-{mysql_insertid} not working in 3.23.38?
x My problem with this is that I have no control over the versioning. I'm
x using an ISP who was gracious enough to upgrade one of the servers (hosting
x our largest clients) to 3.23 because it was having a BUNCH of other
x problems.
x So if the {mysql_insertid} thing is an issue, is there a fix? Does the
x latest DBD/DBI package fix it? Or is it strictly a MySQL issue and just
x needs to wait for a new release?
There is exist two alternative versions of DBD drivers for MySQL on
CPAN at this moment: distribution DBD-MySQL and ditribution
Msql-Mysql-modules. AFAIK first distribution has driver which had bug
with $dbh-{mysql_insertid} in its old versions.
You should ask your ISP to install latest version of
Msql-Mysql-modules or latest version DBD-MySQL. It is better to
install Msql-Mysql-modules because DBD-MySQL is experimental driver.

Re: transactions
Hello All,
I'm current working on project, converting a flatfile system, to use MySQL,
which supports transactions w/Innobase tables. My questions is, as I'm sure many
have coded using transaction w/Perl and DBI. I understand that there as some
draw backs to using transactions when not necessary, but very beneficial, when
needed. What are some good guide lines or rule of thumb to following when
using transactions type tables?
This is from 'man DBI'. I don't think I can add anything to it:
The recommended way to implement robust transactions in
Perl applications is to use `RaiseError' and
`eval { ... }' (which is very fast, unlike `eval ...').
For example:
$dbh-{AutoCommit} = 0; # enable transactions, if possible
$dbh-{RaiseError} = 1;
eval {
foo(...)# do lots of work here
bar(...)# including inserts
baz(...)# and updates
$dbh-commit; # commit the changes if we get this far

RE: [request] IP Address Functions
Hi, I have a feature request: How about adding a built-in function to convert IP addresses from strings to INT UNSIGNED, and another function to convert vice versa. Have you taken a look at INET_ATON and INET_NTOA functions ?? Yes, you might want to take a read of section 7.4.12, 'Miscellaneous Functions', in the current MySQL manual: http://www.mysql.com/doc/M/i/Miscellaneous_functions.html I assume you must also be using an old version of MySQL, as these functions were only added in version 3.23.15, so you should upgrade your installation of MySQL.

RE: MyODBC through ADO
The easiest way to work out what your connection string should be is to create a new text file in explorer, rename it Something.UDL, and double click it: You then get the MS Data Link editor dialog. Select the MS OLEDB Provider for ODBC Drivers as the Provider, select your ODBC datasource (I don't know if you can use a file DSN) and hit the OK button. If you open the UDL file with a text editor, you can read the connection string. I have had problems using the MySQL OLEDB Provider, which is why I recommend using the ODBC OLEDB Provider. First I'l install the MySQL in a remote NT server and also MyODBC in Client machine. Then I'll create a File DSN using MyODBC. Now what Provider name (eg For Oracle MSDAORA) and ConnectString should I give ? - 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?

Question on select
Hello Guys, I have a char field, and I'd like to have select ordering it by lowercase caracteres, uppercase caracters then special characters. I was reading about sort and this seems to be related to charset of the server, and I dont have access to change this. I was thinking on making this select a select of 3 selects. On the first one I'd select where the column starts with [a-z]. On the second one [A-Z], and the third one would be NOT [a-z] AND NOT [A-Z], both three sorted. The question is . how can a query that selects all records having a column STARTING with a-z lowercase Hope hearing from you soon, Leonardo Rodrigues Persocom Network
Re: Got timeout reading communication packets
You are possibly not escaping binary fields. You should use
mysql_escape_string() function on binary objects prior to inserting it
in the INSERT command, or use load_file() function.
Thanks Sinisa for the reply!
There really isn't any binary data.. and, we are calling
mysql_escape_string.. here is the snippet of code:
// START SNIP
int state;
unsigned int encoded_str_length = 0;
MYSQL_RES *result;
MYSQL_ROW row;
char *sql, *escaped_data;
escaped_data = new char[2*strlen(data)+1]; //required by mysql
sql = new char[2*strlen(data)+600];// +1
encoded_str_length = mysql_escape_string(escaped_data,data,strlen(data));
sprintf(sql,%s%d%s%d%s%d%s%d%s%d%s%d%s%d%s%d%s%d%s%s%s,
REPLACE into reflectivity.measurement_extended_data set
content_typeID = ,content_typeID,
, contentID = ,contentID,
, arrayID = ,arrayID,
, positionID = ,positionID,
, testID = ,testID,
, iteration = ,iteration,
, test_locationID = ,test_locationID,
, date_added = ,date_added,
, added_by = ,added_by,
, data = ',escaped_data,');
state = mysql_query(connection,sql);
delete [ ] sql;
delete [ ] escaped_data;
if (state != 0)
{
Application-MessageBox(mysql_error(connection),NULL,MB_OK);
return 0;
}
// END SNIP
And, as I mentioned, if I do something like:
bin/mysql -u -p database foo.sql
where foo.sql contains the query checked for sanity the exact same result
occurs.

can I force SELECT to use a specified INDEX?
Hi, I have a table with several complex indexes: (source,description,timestamp,id) (timestamp,id) as well as individual indexes (id) (timestamp) (type) (source) (description) mysql describe eventlog; +-+--+--+-+-++ | Field | Type | Null | Key | Default | Extra | +-+--+--+-+-++ | id | int(10) unsigned | | PRI | NULL| auto_increment | | timestamp | int(10) unsigned | | MUL | 0 || | type| tinyint(4) | | MUL | 0 || | source | char(15) | | MUL | || | description | char(100)| YES | MUL | NULL|| +-+--+--+-+-++ I perform the following search: SELECT * from eventlog where description like '%...%' order by timestamp desc, id desc; SELECT * from eventlog where source = .. description like '%...%' order by timestamp desc, id desc; For whatever reason, the second search is consistently very slow (20 sec) inspite the fact that there is an index definition to its effect. I find the first search fast - relatively giving me 0~1 on average, 2~5 at worst. Was the 1st search fast because it uses only one index (description) while the 2nd search slow because it uses the complex index (source,description) ?

Re: Got timeout reading communication packets
At a small glance, your code looks OK. Try looking at resulting string sql in gdb or just print it out to stdout. That might catch your bug. Thanks again for the reply. The query looks sane.. As I mentioned, I spit it out to a file and piped it directly to mysql (after inspecting it). At least where it truncates there isn't anything abnormal (the blob is merely a tab delimited string of ints) and the same truncation occurs. MySQL commands lenghts are limited only by max_allowed_packet, which can be extended up to 16 Mb in 3.23 and 4 Gb in 4.0. Nodz.. that's what I thought. This is our setting: set-variable= max_allowed_packet=7096128 Confirmed in variables: | max_allowed_packet | 7095296 It's definately not that big, and, we aren't getting the standard expected errors when you exceed packet size (such as mysql server has gone away).

Re: $sth-{mysql_insertid} not working in 3.23.38?
As of a couple of months ago, there is a bug with DBI's implementation of
$dbh-{'mysql_insert'}. It didn't handle 64-bit IDs correctly. We converted
everything to use SELECT LAST_INSERT_ID(). It works. MySQL is fine, the
problem was in DBI.
Don't use SELECT MAX(ID) ... as that will not do what you want and you'll
corrupt your own data!
Best,
Kyle

my ($id) = $dbh-selectrow_array(SELECT MAX(id) FROM tbl;);
Don't use this!!!

What's wrong with my GRANT example?
Hi, I am sorry for asking stupid questions, but I am at the end of my trials. I simply want to setup a user who can connect from anywhere and write some table and read from another one. Here's what I do: GRANT INSERT, UPDATE, DELETE, SELECT ON sessiondb.SESSION TO dataexport@localhost IDENTIFIED BY 'somepassword'; GRANT SELECT ON sessiondb.LANGUAGELIST TO dataexport@localhost IDENTIFIED BY 'somepassword'; GRANT INSERT, UPDATE, DELETE, SELECT ON sessiondb.SESSION TO dataexport@% IDENTIFIED BY 'somepassword'; GRANT SELECT ON sessiondb.LANGUAGELIST TO dataexport@% IDENTIFIED BY 'somepassword'; FLUSH PRIVILEGES; Looking into the tables tables_priv and user, everything looks good.

problems with MySQL GUI
Hi: Im using Windows 2000, and Im having problems with MySQL GUI. It works intermittently. Sometimes it just closes out for no apparent reason. Sometimes it will not let a known good user log in. Sometimes it will let a known good user log in, but then will not let that user create a database, and then the next time you try it will let the same user create with no problems. Arnie
Re: Got timeout reading communication packets
Sorry to suggest this but is it just possible that the 'data' object you are
doing a strlen on is not null terminated or in fact contains earlier null
characters which are terminating your effort. I have made this mistake several
times when using mysql_escape_string. Now to avoid it I just use pointer
arithmetic.

I have never heard of a problem as the one you describe. MySQLGUI uses normal C API functions for the functions you describe and does not have a will of it's own on that matter. Are there any error messages. Click on the button in the lower left corner of the main window and see if there are any error messages.

Re: DISTINCT AND NON DISTINCT

Is there not an inverse function for DISTINCT, so that I can pull out duplicate data as opposed to DISTINCT data...or will I have to get this information by using joins? Thanks very much for your help. Anna You could use 'group by' like so. x = value that is either distinct or not distinct: Select x, count(*) from table_where_x_is_in group by x having count(*)1; Hope that helps. (BTW, you can also combine fields, but they have to appear in the 'select' and in the 'group by' part. More in the really good manual). I hope that accomplishes what you wanted.

Re: Perl DBI Error 19 -solved
Just if somebody is interested:
I solved the mystery with Error 19. All I needed to do was introducing a
second statement handle for the update query.
(BTW, the script runs probably faster using '$sth = $dbh-do' instead of
'$sth = $dbh-prepare', followed by '$sth = $dbh-execute').

The selected values (primary_id, other_id) are both INT(12) and so are the

Please have a look at the Perl code snippet below. As I said it works for
the first row. BTW if there is pure sql code that would do the job, I would
be delighted to learn about.

FLOAT bug
In doc '21.19 Solving Problems with No Matching Rows' item 5 states. 5.If you are comparing FLOAT or DOUBLE columns with numbers that have decimals, you can't use =! This problem is common in most computer languages because floating-point values are not exact values: mysql SELECT * FROM table_name WHERE float_column=3.5; - mysql SELECT * FROM table_name WHERE float_column between 3.45 and 3.55; In most cases, changing the FLOAT to a DOUBLE will fix this! This is just plain wrong. Floating point values are precise and since the advent of the IEEE standard are generally the same across platforms. The following example fails and is a bug not a problem with the language or the hardware. CREATE TABLE bug1 ( floatType float default NULL ) TYPE=MyISAM; DESCRIBE bug1; INSERT INTO bug1 VALUES (0.0); INSERT INTO bug1 VALUES (1.0); INSERT INTO bug1 VALUES (1.23); INSERT INTO bug1 VALUES (1.5); SELECT * FROM bug1 ; SELECT * FROM bug1 WHERE floatType=0.0 ; SELECT * FROM bug1 WHERE floatType=1.0 ; SELECT * FROM bug1 WHERE floatType=1.23 ; /* no record returned */ SELECT * FROM bug1 WHERE floatType=1.5 ; (The above test was run with an HP client and sever, I haven't run other combinations) There are three possible source for the error. 1) The hardware if a floating point processor is being used (not very likely). 2) The OS encode/decode statement if no fpp is being used (I've seen this problem in the past but it is not very likely today). 3) Encode/decode routines used within MySQL. I don't know the design of MySQL so I don't know if this is possible but if and attempt is made to standardize the bit pattern stored on disk for float values then it is the most likely cause of the problem. BTW: The solution proposed in the documentation is completely unacceptable when you are trying to update a record based on its value. If you used the suggested procedure then you would update all the records between 3.45 and 3.55 which is not acceptable.

Triggers or calculations in the future for MySQL?
Hi... The only cause that I´m on this list is because Blueworld is makeing Lasso Professional 5 with built in MySQL database server. Because I am a Mac person I´m used to the powers of text string calculation in Filemaker pro. The information I have got, tells me that MySQL does not have triggers built in for the same purpose. Is this true? if I have three comlumns in my MySQL_DB: first_name, sur_name, age. I need to have a fourth column that is a concatenated version of this: My name is Mika Sjøman and my age is 21 And I need it automatically to be done by the database server. Is this possible in MySQL? If there arn´t - please make a support for triggers. Warm hugs from the MacOS X community to the DW team of MySQL!

MySQL Presentation Peer Review?
MySQL folks, I'm going to be giving a MySQL Server and Application Performance Tuning presentation at the O'Reilly Open Source Convention in July. http://conferences.ora.com/oscon/ If anyone has the time and interest, I'd appreciate it if you could look over the slides I've prepared and see if I've said anything stupid, missed information, etc. It wouldn't take more than about 10 minutes of time, I think. Since MySQL is very community drives, I figure that it only makes sense to harness our collective knowledge a bit more. I certainly don't have any sort of proprietary knowledge hidden away... I'm just trying to help other folks with the same struggles that many of us have been through. So the more input, the better off we are. And, of course, I'll put you in the credits. If you're interested, please mail me privately and I'll get you the URL and try to set your expectations a bit. :-) As a side note, I'm doing another presentation on a MySQL topic (roughly on the topic of Building a Perl API for fault-tolerant MySQL/Perl applications) later on this year. I don't have slides yet, but if you'd like to look at them when they're done and tell me what I'm missing, I'd appreciate the help. Thanks, Jeremy -- Jeremy D.

I Think I Need ' H E L P' on table's privileges
HI: I need some help on table's privileges, I've read the manual but still don't get it working. Background: I'm working on a windows program which needs to connect to a MySQL database on a linux server using MyODBC32. I've installed and configured MyODBC and MySql as follows: Supposing my linux server has the IP address 192.168.3.1 , my windows client has the IP address 192.168.3.2 and ODBC32 (on windwos client) has the following parameters under User DSN tab: Driver: MySQL WindowsDSN: linuxsvr MySQL host: 192.168.3.1 MySQL database name: water After Installing MySQL on linux I set it up like this: #Installing the grant tables ./scripts/mysql_install_db #Starting daemon ./safe_mysqld --user=mysql #Setting root password ./mysqladmin -u root password hello #Creating database .-mysqladmin -u root -phello create water #grant all privileges to a user called mortz conected from any node ./mysql -u root -pwater mysqlgrant all privileges on water.* to mortz@'%' identified by 'hello' with grant option; This way didn't work, whenever I try to connect from my windows program, after the login prompt from MyODBC a message appears telling me access denied for user mortz. I tried this way too: mysqlgrant all privileges on water.* to mortz@'192.168.3.0/255.255.255.0' identified by 'hello' with grant option; but still doesn't work After I tried to connect from the linux server using the client and same user mortz: ./mysql -u mortz -phello water and I did connect, it means the local privileges are OK but I can't connect from outside. I know there are no tables in the database water but that's precicely what I want because I'm creating a program which uploads data (and tables) from dbase4 to MySQL how ever I can't even create tables if I don't get access first...

Modifiying values in table_a with values from table_b
What I want to do is not overly complicated (and it works the way I did it) but I want to find out if it can be done easily using MySQL only. Table_a: col1, col2, col3 Table_b: col1, col2, col3 Currently, to replace values in col1 in Table_a with values of col2 in Table_b, I do the following: while read col1 col2; do echo col1 echo col2 # so I can see what's happening mysql -uuser -ppassword database eof UPDATE Table_a SET col1 = $col2 WHERE Table_a.col2 = $col1 eof done Table_b # data from comma delimited file (exported) I hope that you can see what I am trying to do. I tried to do the same thing prior to importing it into MySQL but gave it up. It was simply too long to go over two WHILE loops with 1600 and 95000 records respectively. So now, I have this kludge where I have glued shell script with MySQL. How could I accomplish the same in MySQL alone?

Sub-selects in a insert statement - is it possible to rewrite?
As I've understood it mysql doesn't support sub-selects inside for example insert statements (apart from inset ... select). Background-stuff: What I'm working on is parsing logfiles and inserting them into a mysql database through the C API, to minimize traffic and to maximize time, I was hoping I could get away with a single insert query instead of having to do a select and then use that information to form a insert. This is how I'd like the query to work: insert into host (host_id, host_IP) values ((select from mail mail_id where mail_addr = [EMAIL PROTECTED]), '127.0.0.1') The table host has columns: email, host, host_id where host_id would be used as a forreign key in a table with the actual log entries in. Is it possible to do this in a single INSERT or would I have to use a select and then a separate insert? I'm open for any suggestions (and no the host columns shouldn't be normalized into the table with the log entries as that would be a table with 200k+ rows, and I'd prefer to have hosts in a separate table to make it easier to present a list of hosts that have logged something without doing queries on the much bigger log table).

Data Entry Forms
I've created a MySQL database and linked the tables to a MS Access front end so that I could build the data entry forms using MS Access. Is there a better way to create the data entry forms in a Windows environment without using Microsoft or proprietary solutions? What is are the most widely used methods for creating data entry forms for MySQL in a Windows environment?

RE: Kylix with MySQL
The problem is that Kylix does not yet support libmysqlclient.so.10, only libmysqlclient.so.6. You only have to replace the client libs. I used the ones from 3.22.32 and they work fine. Kevin McBrearty ATG Automation Technologies Group Ltd. -Original Message- From: Bagi kos [mailto:[EMAIL PROTECTED]] Sent: Monday, June 25, 2001 6:07 AM To: [EMAIL PROTECTED] Subject: Kylix with MySQL Hi Everybody! I want to develop some database application under RedHat 7, with Kylix using MySql. I'm using MySql 3.23.38. It uses libmysql.10, default limbysql.6. Kylix native MySql driver cannot connect to MySql server on the same (neither localhost, nor IP) but MySql is Accessible from Windows/ODBC via network, and with the MySql Clients. Error: Invalid UserName/PassWord. Does anybody have some information how to solve the problem? I would use the highest MySql Version. I heard somewhere that Kylix supports libmysql.6 only. If that's the problem what is the highest MySql version using that lib. Shall I change the whole MySql installation or the libfile only? I would appreciate some help. regards Akos - 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: Data Entry Forms for MySql
Hello I often use an html editor to create forms, use PHP4 as a cgi and enter the data directly into MySql. This does not necessitate Microsoft, and has worked very well for me. -warren - Original Message - From: Stephen Reynolds [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 25, 2001 8:24 PM Subject: Data Entry Forms I've created a MySQL database and linked the tables to a MS Access front end so that I could build the data entry forms using MS Access.

Re: Data Entry Forms
You have several options, a few of the more common solutions include: C, C++, Delphi, Perl, PHP, HTML, CGI, etc... Simple data entry forms can often be easily implemented using a web-based solution (which also simplifies deployment)...

HP-UX 10.20 and MySQL
Is there some kind soul out there that can email me a tarball og the MySQL module for an HP-UX machine? I've tried to compile the module - but it says that I have to compile MySQL with +z or +Z, gcc doesn't have a +z or +Z ( and mysql should be compiled with gcc ) but it does have an -fPIC and -FPIC, which matters all the same to the compilation of the MySQL module: The error is: LD_RUN_PATH=/opt/mysql/lib:/lib/pa1.1 ld -o ./blib/arch/auto/DBD/mysql/mysql.sl -b -L/usr/local/lib dbdimp.o mysql.o -L/opt/mysql/lib-L/opt/mysql/lib -lmysqlclient -lm ld: DP relative code in file /opt/mysql/lib/libmysqlclient.a(libmysql.o) - shared library must be position independent. Use +z or +Z to recompile. *** Error exit code 1 Stop. *** Error exit code 1 Stop. Can somebody email me the compiled module? Correct me if I'm wrong?
