Re: databases and operating systems
Ok. Now you make more sense. This is from my personal point of view. In general, I prefer speed, ease of use and ease of maintenance. What I like about mysql is that you can choose which features to build into it when compiling. For example, standard mysql does not come built with transaction support and, as transactions tend to take up time, I prefer not to use it. You don't have much of a choice in other database packages. Sure mysql lacks functionality, but that will come as the developers progress. The other bells and whistles, that come with most other products like Oracle MSSQL server, aren't used very often and usually tend slow down queries, whether they're used or not. - Original Message - From: "Ben Garvey" [EMAIL PROTECTED] To: "Rolf Hopkins" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Friday, April 20, 2001 13:43 Subject: Re: databases and operating systems Sorry for the topic if if is off, but there are more uses for databases than just in PCs.

Merge Tables Oversight
Hi all, I think I may have come up against a slight niggling omission concerning Merge tables. How does one find out what physical tables are mapped, other than by looking at the contents of the .MRG file? Surely this information should be displayed either when you do SHOW TABLE STATUS or by some other means? For example, I am currently using a Merge table to map 68 stats logging tables into one giant table (3.5 million rows!) so that overall averages, etc. can be calculated. As the mapping for this Merge table changes often, it would be handy for me to be able to check the current state of the mapping without leaving the MySQL client. I think a list of the mapped tables (or perhaps rather the UNION() statement) could be shown in the Create_options field of the SHOW TABLE STATUS output, as I would assume this is the appropriate place, yes? Maybe someone can tell me if there is any particular reason why this can't be shown, or is it just an oversight?

recommend a good book for connecting from mysql to other dbs
Dear Tom - (Please bear with me for a philosophical prolog.) Tom Beidler writes: I'm running into more and more clients that would like to connect to another database. Say there inventory tracking software. I was wondering if there was a good book out there or a web site that might have some info that I can use to start thinking about strategies of connecting other dbs. PROLOG (See RESPONSE to escape ranting) This question highlights what seems to me to be a consistant theme throughout the list that I don't understand. The DBAs I've worked with in my career tell me that you should always err on the side of excessively methodical. That is, don't enter commands interactively but instead put your SQL in a script and run the script against a test database and only execute it against the production system when you've got it perfect. This ensures that your database machinations are reliably repeatable. Many of the questions on the list sound to me like "How do I write a set of SQL commands that will confirm the validity of a credit card number?" My confusion is, why on earth would you want to? If you're already using a scripting language (at least sometimes) to wrap your SQL then why don't you let it handle these sorts of problems. SQL and the DBMS are absolutely superior at handling a FEW very specific problems (i.e. sorting, writing, fetching). SQL is horrible at everything else. So, back to Tom's original question. Interfacing with other databases potentially in other DBMSs or maybe even data that isn't in a database is not really a database task. It's a programming task. The question that I would want answered is "I want to merge multiple data sources what tool will allow me to do that with all the different types of data I'm interested in?" RESPONSE The answers vary, of course, depending on what the data sources are but you should investigate what is referred to as "ETL" (Extract, Transform, Load). There is an extensive literature around this topic in the data warehousing realm. I'll plug my own preferences and suggest that you solve your problem with scripts written in perl. Perl has available with it a database abstraction mechanism called DBI/DBD that will allow you to access multiple databases in different DBMSs (and here's the kicker) without having to write code that is idiosyncratic to the DBMS. That is, the DBI abstraction allows you to write data sorting, writing, fetching logic (see philosophical ranting above) that is independent of the DBMS which is used to maintain the data.

capturing mysql errors in Perl
Hi, I've got a problem on one of my clients' servers, which is, that the errors mySQL throws are not captured by the Perl CGI using mySQL, but are thrown regardless, meaning that a CGI that provokes an error in mySQL will produce an unspecified "Internal Server Error", which is not very helpful for debugging purposes.

Re:weird indexing behavior in presense of LIMIT
Hi!
Andrey is right, if I understood correctly. MySQL should notice that
the index with two columns (color, randomkey) is the best because we
have an equality condition on the first column color (= "black")
and an inequality condition on the second column randomkey ( 30).
Then MySQL can start the search with a key value
("black", 30)
from the index and step forward in the index until the color value
changes from "black" to something else.
To estimate the number of rows in the result set, MySQL should
estimate how many index records fall in the range
("black", 30) ... ("black", MAXINT)
Thus it is an issue of optimizing also inequality conditions into
the search parameters when that is possible. It does not happen very often
that inequalities are useful but in this example it would be.
If we only would have indexes on single columns color and randomkey,
then there is not too much help from optimization. IBM's DB2 in these
cases performs a 'hybrid join' which means that it does first
a search on the first one-column index, then sorts the row pointers,
then repeats the same for the second one-column index, and then
compares which row pointers are in both sets.

Heikki
Hi!
"Andrey" == Andrey Gubarev [EMAIL PROTECTED] writes:
Andrey Here is a very easily reproduceable problem with mysql indices:
Andrey Suppose we have two columns, color and randomkey. color is
enum("black",
Andrey "red", "blue"), black being 95% of all color values, and randomkey
is an
Andrey integer between 1 and 100. We also have two indices, one on
randomkey,
Andrey and one on (color, randomkey).
Andrey The query
Andrey select * from my_table where color = "black" and randomkey 30
Andrey limit 10
Andrey looks simple enough. One would expect mysql to use either the randomkey
Andrey index (because the vast majority of rows are black anyways), or the
color-
Andrey randomkey index.Andrey In fact, the query above takes minutes.
Andrey Mysql uses only the first part of the color-randomkey index (i.e.
color)
Andrey and examines 30 rows before it finds randomkey 30
(assuming the
Andrey table has one million rows). Why? Wouldn't it make more sense to
use all
Andrey available indices when LIMIT is used?
An index is bascily just a sorted list of keys and pointers to rows.
You can't search on two of these at the same time.
MySQL works the following way to solve the above query:
- Check how many rows satisifes the condition: colur="black"
- Check how many rows satisifes the condition: randomkey 0
- Use the key that is smaller.If you compare this to a telephone book:
Assuming you have two telephone books, one where all entries are
ordered by first name and a second where all names are ordered withlast name.
How would you use the fact that you have two books when you are
searching after 'John Smith' and there is one million Johns and one
million Smiths? Note that under 'John' the last name comes in random
order and under Smith all the first names comes in random order.

Another little question... If it's necessary only the ODBC, i must install them by the set-up downloaded from the site or can i copy and register the dll of ODBC? Well, that's a question that I have wrestled with also. There was a recent post (on 4/19/01) by one of the MySQL developers (Miguel Angel Solorzano) that addresses this issue, I would search in the archives for it. I haven't tried it just yet, but it does seem like a possible solution.

Re: Merge Tables Oversight
Hi, On Fri, Apr 20, 2001 at 01:41:15PM +0100, Basil Hussain wrote: I think I may have come up against a slight niggling omission concerning Merge tables. How does one find out what physical tables are mapped, other than by looking at the contents of the .MRG file? Surely this information should be displayed either when you do SHOW TABLE STATUS or by some other means? I never use SHOW TABLE STATUS, but you can use SHOW CREATE TABLE which will give you the complete CREATE TABLE statement for the MERGE table. This doesn't include the UNION part in MySQL 3.23.33, but I believe this was fixed in MySQL 3.23.36 and later. Actually it was implemented in 3.23.34, but 3.23.34 and 3.23.35 were retracted because of some serious bugs. I did think of SHOW CREATE TABLE, but it didn't turn up anything when I tried it - now I know why. I'm using only version 3.23.32. Do you know if this fix in 3.23.36 is only concerning the client utilities, or would I have to upgrade my server too? It's in the server. I don't use 3.23.36 (or 37) yet because this is not important enough for me to warrant an update. My work-around is to list all tables and assume that all names with a certain prefix are part of the UNION (this should always be the case in my implementation). I still think the mapped tables should be shown in SHOW TABLE STATUS, though... I didn't test it (I still use 3.23.33 with a patch) but the change list says nothing about SHOW TABLE STATUS, so this probably hasn't changed. FWIW, I agree with you.

Re: databases and operating systems
Ben, the relation of databases and OS's is a question also mentioned in Jim Gray's and Andreas Reuter's bool Transaction processing. I have written the InnoDB table handler (= storage engine) under MySQL. Let me think how operating systems could make database implementation easier. - Log-based file systems could take the role of recovery mechanism in case of a crash. For it to be feasible, the file system should immediately write a log to a safe place of any changes to files cached in the file cache of the OS. I do not know if such database-like file systems exist. - The file cache of the operating system could take the place of the buffer pool of the database. This is actually done in MySQL because MySQL caches the data of rows in the file cache of the OS. Only indexes are cached in MySQL's own 'key cache'. - The file system of the OS can do the storage of tables and indexes into regular files. That is how MySQL actually works. In InnoDB I decided to build my own file space management, where the database takes care of space allocation in a 'tablespace' consisting of one or more files. - Many databases implement their own thread abstraction above the processes or threads of an OS. The reason is that OS threads use too much memory, or thread scheduling is slow in the OS if there is alarge number of threads. MySQL uses OS threads or a user-space library threads, and does not implement its own thread abstraction. InnoDB engine has its own thread abstraction above OS threads. There are many performance-related viewpoints to the above questions. Generally the services of operating systems are not as highly optimized code as what is found in databases, and database implementors have written their own modules to get the best performance. - A special detail is semaphore (like a mutex) implementation. Datbase implementors have tradiitionally written their own semaphores using a test-and-set machine instruction. It would be better if an OS would provide such a fast semaphore operation in a library. I looked at FreeBSD source code and found that a pthread mutex there is still much more complex, and consequently slower than a mutex I can write myself using a machine instruction. However, in Win NT a 'CriticalSection' corresponding to a mutex is very fast, I think. For portability it would be better to use OS mutexes. Thus an OS could to some extent help the work of us database implementors. But the services of the OS should then be written to be fast enough. - Standardized interfaces is a very important property of an OS from the database viewpoint. Databases use quite a rich set of OS services and deviations from (Posix) standards in an OS cause quite a lot of work in form of portability bugs. Hope this helps your work. Regards, Heikki Tuuri Innobase Oy Ok. Now you make more sense. This is from my personal point of view. In general, I prefer speed, ease of use and ease of maintenance. What I like about mysql is that you can choose which features to build into it when compiling. For example, standard mysql does not come built with transaction support and, as transactions tend to take up time, I prefer not to use it. You don't have much of a choice in other database packages. Sure mysql lacks functionality, but that will come as the developers progress. The other bells and whistles, that come with most other products like Oracle MSSQL server, aren't used very often and usually tend slow down queries, whether they're used or not.- Original Message - From: "Ben Garvey" [EMAIL PROTECTED] To: "Rolf Hopkins" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Friday, April 20, 2001 13:43Subject: Re: databases and operating systems Sorry for the topic if if is off, but there are more uses for databasesthan just in PCs.

Replication and compression
Is it possible to enable compression between replicating database servers? I'm assuming that there is already compression code in place, because of the need to link with the compression libraries on the client end sometimes. Compressing the replication connection has certain advantages where the connection speed is slow, and the servers at either end are not being stressed due to slow data transfer.

I'm trying to discover the best way to troubleshoot this problem. I tried upping the user max_connections variable but that didn't help...

capturing mysql errors in Perl

It looks as if mySQL goes straight to the OS with the error, instead of giving Perl the chance to handle it? And how can this be avoided? Hmmm, maybe I'm not interpreting your message correctly, but it sounds to me like you're experiencing the standard CGI error handling problem along with perhaps some signal handling. CGIs are awkward to debug using standard web browsers because normally error messages don't have HTTP headers so all you ever get is "Internal Server Error". That's what the browser says when you pass it information that's not properly formatted HTTP. The best way to deal with this problem is to use a pretend browser like the command line or emacs W3 and debug your code that way. As to the perl signal handling I would go to the "Advanced Perl Programming" book. I'd be willing to take a look if you want to share the offending code.

I want to use logging to restore the database in case of another crash, but I can't figure out how to restore from the logs. If you know, please let me know. Thank you in advance, Lee Jenkins

64MB Limit on MyISAM indexes?
I've got tables in ISAM format whose indexes are way over 64 MB. However, when I try to create a MyISAM table with an index that big I get errors and confirming that with myisamchk I get: myisamchk: warning: Keyfile is almost full, 67107839 of 67107839 used Which is essentially 64MB. Are MyISAM tables able to handle large indexes? I hope I don't have to go back to ISAM tables... Any suggestions?

why doesn't this work? (C code)
G'day,
This USED to work, then all of a sudden for no apparent reason it has
suddenly decided not to:
if I change the code thus:
if(*row1[2] == 'l')
{
;
}
else if(*row1[2] == 'e')
It completes, but of course this isn't any good.
Is there something fundamentally wrong with using the same connection
for more than one 'cursor'? I understood that mysq_store_result()
simply writes the result set to a 2D character array. T4 there
should'nt be a problem.

Subject: Possible bug in 3.23.32 or later
Description:
When i insert into a negative integer into primary key (id int) field,
it
works fine.
However, the next insert i do without specifing the id explicitly and
relying on mysql to
generate the next number in the sequence (should be 1) will use the
upper
bound (2^32 - 1)
Then every other insert after that will not insert since there are no
id's
available.
How-To-Repeat:
CREATE TABLE category
(
idINT NOT NULL AUTO_INCRE17;6,
name VARCHAR(50) NOT NULL,
code VARCHAR(50) NOT NULL,
description TEXT,
picture VARCHAR(50),
parentINT NOT NULL DEFAULT 0,
activeTINYINT,
members INT NOT NULL DEFAULT 0,
storeid INT,
feature1 INT NOT NULL DEFAULT 0,
feature2 INT NOT NULL DEFAULT 0,
priority INT,
KEY (code),
KEY (name),
PRIMARY KEY (id)
)\g
INSERT INTO category
(id,name,code,description,picture,parent,active,members,storeid,feature1,
fea
ture2) VALUES (-10,'NEW','NEW','All new products','none',-1,0,0,1,0,0);
Then try:
INSERT INTO category
(name,code,description,picture,parent,active,members,storeid,feature1,featur
e2) VALUES ('test','test','All test products','none',-1,0,0,1,0,0);
That should make the id 2^32 -1 (or something aroudn there).
That id should be 1!!!

Convert varchar to number field
Hi, I started a table with a varchar filed of 11 characters for a column that would hold data such as 0.27; 11; 0.6; 1; 5; 7.5; 11.2; etc I wasn't sure if a 'number' field would work. Now I want to list the values in this column and they do not list numerically, for example: if we had 0.27; 0.6; 1; 5; 7.5; 11; then 11 would come before 5 and 7.5 (alphanumerically). What I need is them to list numerically, so they would list like: 0.27 0.6 1 5 7.5 11 11.2 Any advice on what to change the field type to or how to convert it at the time of querying via PHP would be great.

Subject: complicated query
I would like to do something similar to an ORDER BY
in one of my select statements, but I'mt not sure
how to do something as complicated as this:
I have two columns, category and subcategory, that
I am retrieving. I would like category and subcategory
to be sorted alphabetically. This is easy with an
'ORDER BY 1 2', but I would like categories that
are named 'other' to be put off until the end. So,
I'd get something like this:
abcd
ghikj
z
other
Is there a way to do this type of query? Thanks in
advance.

MySQL newbie questions.
Does anyone know exactly where to put the mysql.server file? is it in /etc? When I run it I get these ./mysql.server: @HOSTNAME@: command not found ./mysql.server: my_print_defaults: command not found Which leads me to believe I'm doing somthing wrong.

Re: Convert varchar to number field

Now I want to list the values in this column and they do not list numerically, for example: if we had 0.27; 0.6; 1; 5; 7.5; 11; then 11 would come before 5 and 7.5 (alphanumerically). What I need is them to list numerically, so they would list like: 0.27 0.6 1 5 7.5 11 11.2 Any advice on what to change the field type to or how to convert it at the time of querying via PHP would be great. Thanks. Use an ALTER TABLE statement. Something like the following: ALTER TABLE table_name MODIFY field_name DECIMAL(4,1) UNSIGNED Make sure you choose a numeric type that is appropriate. See the online manual for options. If you're worried you might ruin your data with this conversion first create a copy of the table and experiment on it instead.

Are you sure this works? My query is:
select category,subcategory from categories ORDER BY

And I get:

Yes. And I of course tested before I posted. I also tried
ORDER BY category in ('cat1','cat2'), category
which worked.
I'm running 3.23.36 on debian linux.
Well, actually, rather than create a new table, I used an existing one.
The actual statement was
select last_name from mizpah where first_name like 'fr%' order by
last_name = 'crosby', last_name;

RE: max FULLTEXT index size?
Sergei, I wanted to say thanks so much for your help with this. I went through the bitkeeper install, downloaded mysql 4.0, compiled under solaris 2.7, and the process of creating the big index that took days under 3.23 took 15 minutes. So thanks very much!

largest timestamp value
What's the largest possible timestamp value before it rolls over? I'm trying to figure out what's the best way to do the following. I have a table that has these three fields in it: priority int(3) end_time timestamp(14) start_time timestamp(14) NOTE: only start_time gets inserted as Now() (or NULL so it automatically gets set) end_time is a variable that gets set depending on what the user picks for time period. And I'd like to select and order like: select * from table order by priority, end_time, start_time; Now, some rows will have a valid start, and end times. Others will have only a valid start time, and an undefined end time, or infinite if you will. However, if I don't fill in a value for that field, MySQL dutifully puts in 00 for me, and when I perform the above query, I get something like this: +--+++ | priority | end_time | start_time | +--+++ |0 | 00 | 20010329023143 | |0 | 20010330231405 | 20010329021805 | |0 | 20010331012712 | 20010330162312 | | 10 | 20010422051135 | 20010419161205 | | 10 | 20010422051135 | 20010419162335 | | 50 | 20010330131222 | 20010329015222 | | 50 | 20010330131703 | 20010329015703 | | 100 | 20010331192630 | 20010329014630 | | 100 | 20010401211100 | 20010330023100 | +--+++ However, I want that first row, to end up last within that priority level (so drop it to line 3). The only thing I can think of is to put in some insanely large value for that timestamp, so that the select clause works. So, I need to figure out what's the largest possible amount of time I can put in, and make it like a 'dead end' value. Anything that has that value is considered infinite. I suppose I can put in 2038010100...but is that the ceiling of MySQL? Unless there's another way? -- W | | I haven't lost my mind; it's backed up on tape somewhere. | ~ Ashley M.

Here is the relevant information from the binary log (the slave's replication thread stops at position 165791771):: # at 165791547 #010420 15:11:34 server id 1 Querythread_id=590431exec_time=0 error_code=0 use pollit; SET TIMESTAMP=987804694; UPDATE pollit.sitelog set views=views+1 where pageID='104' and logdate='20010420'; # at 165791659 #010420 15:11:34 server id 1 Querythread_id=590431exec_time=0 error_code=0 use pollit; SET TIMESTAMP=987804694; UPDATE pollit.sitelog set views=views+1 where pageID='325' and logdate='20010420'; # at 165791771 #010420 15:11:14 server id 1 Querythread_id=604315exec_time=205 error_code=0 use adserver; SET TIMESTAMP=987804674; UPDATE LOW_PRIORITY bancamp_rel_set SET views=views+1 ,track=track+(1/weight) WHERE BID='518794397' AND setID='18114'; # at 165791923 #010420 15:11:14 server id 1 Querythread_id=604297exec_time=205 error_code=0 use adserver; SET TIMESTAMP=987804674; UPDATE LOW_PRIORITY bancamp_rel_set SET views=views+1 ,track=track+(1/weight) WHERE BID='518819786' AND setID='32880'; # at 165792075 All the queries before pos 165791771 have exec_time = 2 and all the queries after exec_time 205. Thousands of queries pile up in the process list on the master. Stopping the slave using 'slave stop' immediately fixes the problem.

Re: 64MB Limit on MyISAM indexes?
You need to change the "maxrows" on the table. It is in the documentation, I dont remember the exact syntax something like "alter table tablename set maxrows=1" for tables larger than 2gigs. ryan I've got tables in ISAM format whose indexes are way over 64 MB. However, when I try to create a MyISAM table with an index that big I get errors and confirming that with myisamchk I get: myisamchk: warning: Keyfile is almost full, 67107839 of 67107839 used Which is essentially 64MB.

RE: Need help with a Freebsd install..
Larry, if you haven't resolved this yet - you might want to install from the sources, like I do. I am also running FreeBSD 4.2, here is what I did, and it seems to work like a champ. 1) get the source from www.mysql.com/Downloads/MySQL-3.23/mysql-3.23.37.tar.gz 2) put this file in some directory on your system (mine is /usr/src) 3) go to that directory and run 'gunzip mysql-3.23.37.tar.gz' 4) now run 'tar -xvf mysql-3.23.37.tar' 5) now run 'cd mysql-3.23.37' 6) type './configure --prefix=/usr/local/mysql --localstatedir=/usr/local/mysql/data --with-mysqld-user=mysql --with-thread-safe-client --enable-assembler' 7) now type 'make' 8) then 'make install' 9) now, it should be installed to /usr/local/mysql, but we told mysql that we want to run it as user 'mysql' (--with-mysqld-user=) so, create a user account named 'mysql' and make him part of the group 'mysql' by running 'adduser' 10) now you can create the grant tables if they aren't already there, run '/usr/local/mysql/bin/mysql_install_db' 11) now, make sure the user 'mysql' has access to the mysql stuff, run 'chown -R mysql /usr/local/mysql' and 'chgrp -R mysql /usr/local/mysql' 12) also, make the start/stop scripts executable by him, run 'chmod u+x /usr/local/mysql/share/mysql/mysql.server' and 'chown u+x /usr/local/mysql/share/mysql/mysql.server' 13) now, the last thing is to copy the mysql config file to /etc (this will make the config options global), so do this 'cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf' and be sure to look at the file /etc/my.cnf to see if you need to change anything there. 14) now we should be good to go, test the server by running '/usr/local/mysql/share/mysql/mysql.server start' it should start just fine, you might even want to check the error logs in /usr/local/mysql/data/(whatever.foo.bar.err) I hope this helps you out!

why doesn't this work? (C code)
G'day,
This USED to work, then all of a sudden for no apparent reason it has suddenly decided
not to:
if I change the code thus:
if(*row1[2] == 'l')
{
;
}
else if(*row1[2] == 'e')
etc.
the cgi programme completes, so I don't think the problem is elsewhere.
Is there something fundamentally wrong with using the same connection for more than
one 'cursor'? I understood that mysql_store_result() simply writes the result set to a
2D character array. T4 there shouldn't be a problem.
Any help much appreciated

Re: mysqld: immediate Segmentation fault
Date: Thu, 19 Apr 2001 20:41:17 -0700 From: Van [EMAIL PROTECTED] I might be partly responsible for this since MySQL didn't show up in the slackware distribution until I built one for the DEC Alpha. It's running great on my Alpha at version 3.23.33 and I'm staying there until the 3.23.3x versions settled down. The Slackware package itself works great for me. I haven't been able to compile MySQL in quite a while, so I was really glad to find this one. The only problem with it is when I try compiling other things, like MyODBC. [...] Personally, I run all Slack systems and build from source without problems. I put a /mysql partition on the servers when I install them and use the following to configure: ./configure --with-mysqld-user=mysql --localstatedir=/mysql Actually, I use a single "data" user for all my databases. I occasionally play with postgresql and I've tried a few others, but MySQL is my current favorite. The example I gave omitted the user because I've tried it with and without and with various other values, and the user has no effect on the result. Segfault. Never have problems with it. Of course, make sure you have the mysql user added to your system. Well, I have a "data" user instead, but I did check that. That's the user the working daemon runs as with no problems. The daemon I compiled doesn't care what the username is. It just doesn't run. Hope that gives some insight. BTW, the package I built for the Alpha is still running to this day, so I'd be curious to hear that some of the files were omitted. If anything, there should have been more than necessary (src included for instance). Okay, then here's an example: Compiling MyODBC-2.50.36 with the Slackware MySQL package in /usr (3.23.34) gauss:~/download/MyODBC-2.50.36./configure --enable-static --enable-shared --with-mysql-libs=/usr/lib/mysql --with-mysql-includes=/usr/include/mysql --with-unixODBC --with-iodbc [...] checking for the mysql client libraries... /usr/lib/mysql checking for mysql_real_query in -lmysqlclient... yes checking for mysql include files in /usr/include/mysql... yes checking for sql.h... yes checking for sqlext.h... yes checking for odbcinst.h... yes checking for SQLGetPrivateProfileString in -lodbcinst... yes checking for SQLHENV... yes checking for SQLHDBC... yes checking for SQLHSTMT... yes checking for SQLINTEGER... yes checking for SQLUINTEGER... yes checking for SQLSMALLINT... yes checking for SQLUSMALLINT... yes checking for SQLPOINTER... yes checking for SQLHWND... yes checking for SQLRETURN... yes checking for SQLCHAR... yes updating cache ./config.cache creating ./config.status creating Makefile creating myconf.h gauss:~/download/MyODBC-2.50.36make /bin/sh ./libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/include/mysql -Iyes/include -g -O2 -c catalog.c mkdir .libs gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/include/mysql -Iyes/include -g -O2 -Wp,-MD,.deps/catalog.pp -c -fPIC -DPIC catalog.c -o .libs/catalog.lo In file included from /usr/include/mysql/my_sys.h:588, from myodbc.h:24, from catalog.c:9: /usr/include/mysql/raid.h:41: my_dir.h: No such file or directory make: *** [catalog.lo] Error 1 Exit 2 gauss:~/download/MyODBC-2.50.36 Looks to me like some of the MySQL include files weren't in the Slackware package. That's why I'm trying to compile from source. I suppose I could just grab the 3.23.34 source and manually install any files that seem to be missing, but that strikes me as a particularly awkward and unreliable solution. I'd much rather just solve the problem than play hit-and-miss at working around it. -- -Dave Noelle, [EMAIL PROTECTED] -the Villa Straylight, http://www.straylight.org Coalition Against Unsolicited Commercial Email == http://www.cauce.com Disclaimer: The opinions expressed above relate in no way to anything at all and are merely the ramblings of an over-stressed C.S. geek: read at own risk Quote of the Day: It's hard to soar like an eagle when you are surrounded by turkeys. - 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?

For example i have 3 tables (really i have to make it with 6 tables, but...) So 3 tables: Table1 uid| name 1user1 2user2 3user3 Table2 iduidc 1150 2123 3142 4223 52303 Table3 idctxt 123'twenty-three' 242'the reason of life' 350'50' 4303'303 rulz' how can i get a recordset constains all records (or records matching a where exp.) from the Table1 with the c values from the Table2, like this: uidnamecs - 1user1'50 - twenty-three - the reason of life' 2user2'twenty-three - 303 rulz' 3user3'' I can make heavy things with mysql, but i'm too small for this :) thanx: Z - 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?
