installation problems
I purchased a book entitled PHP3 programming browser-based Applications it came with a cd that contained a copy of MySql-3.22.16a-gamma for any linux distribution. Anyhow, I am having problems installing the software on my SuSe 7.1 linux box. Basically, there are eleven steps that the author david medinets requires in order to properly install the software, but of those eleven, I am having problems with step 8. From root directory linux: ~ # - 1 cd /usr/local/src/mysql-3.22.16a-gamma 2 ./configure --prefix=/usr/local/mysql 3 make 4 make install 5 echo /usr/local/mysql/lib/mysql /etc/ld.so.conf 6 ldconfig -v | grep libmysqlclient 7 echo /usr/local/mysql/bin/safe_mysqld /dev/null /etc/rc.d/rc.local 8 ./scripts/mysql_install_db 9 /usr/local/mysql/bin/safe_mysqld /dev/null 10 ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql 11 ln -s /usr/local/mysql/bin/mysql /usr/bin/mysqlshow after this, the author gives you a sample code to test the database. _ step 8 after entering this at the prompt: linux: usr/local/src/mysql-3.22.16a-gamma # ./scripts/mysql_install_db an error message ( did'nt find /usr/local/mysql/libexec/mysql ) ( You should do a make install before executing this script ) I tryed to run the sample code with out this being installed correctly, but no luck.

Char set Win1250
Hello, I have simple question.I have installed on my computer WinNT 4.0, Apache 1.3.14, PHP4 (4.0.4pl1), MySQL MAX 4.0.1. There's problem with char set win1250. I don't know how can I link this char set. Script with this row $spojeni = MySQL_Connect(localhost); sends an error Warning: MySQL Connection Failed: Can't initialize character set 26 (path: default) in c:/program files/apache group/apache/htdocs/tellib.php on line 84. (Char set 26 is Win1250). Does anybody know, how can I link char-set Win1250 in Win32 system to PHP4 and MySQL? In PHP3 works everything properly.

Re: mysql japanese
Aravind NagaVenkata Gorthy repeated himself: Dear All Could any one tell me what all the chages I have to make in order to make my existing (english version) of MySQL database compatable to the Japanese language. So I repeat myself: Boy. That's a tough one. I'm really not sure what you want to know. Do you want to convert the whole thing to Japanese for a Japanese-only audience? Do you want to have a Japanese version of you database that is structured the same as your English version? Do you want to store both Japanese and English together? Do you want to be able to search and sort the Japanese data? Or would it be enough to store Japanese data? Or do you simply want to show the English data in Japanese web pages? Do you know which encoding your tools use? Do you know which encoding you'll be getting most of your data in? Do you need a discussion of what the web environment is like over here, so you can base your decision about character encoding on that? I can throw some random information at you. (You know, shot-in-the-dark.) The settings necessary to sort and search in a different language are explained in section 4.6 of the manual. Is there something there you don't understand? Let's see. If you plan to search and sort Japanese, you'll need extra pronunciation (kana) fields. Sorting on Kanji does not give results that the average Japanese person will think very useful. There are three families of character encoding in common use in Japan, JIS, euc-JIS (*NIX), and shift-JIS (PC/ClassicMac/etc.). Unicode is not (yet?) commonly used in Japan, but converters exist, and mostly give good results. MySQL seems to support euc-JIS best. It does not yet support Unicode or straight-JIS for searching and sorting, athough you would be able to store them okay. We are using MySQL with shift-JIS in house, but I'm not sure how well the searching and sorting work. Shift-JIS is a pain to parse, by the way, and I'm sure that's why MySQL doesn't fully support it yet. Incidentally, JIS includes a base Latin character set, but that character set can only be viewed with Japanese fonts. Shift-JIS and euc-JIS both include two Latin character sets, one of which is (almost) 7-bit ASCII. JIS is constant 16-bits wide, and shift-JIS and euc-JIS are both multi-byte, so you can actually (sort of) mix Japanese and English using shift-JIS or euc-JIS, and there is a moderate probability of the English being legible in an English font. But we don't know if any of that is meaningful to you, because we don't know what you want to do. We don't know what tools you have, what character sets they work with, etc. And we don't even know for sure if you are going to try to keep English and Japanese together in one database, or if you plan to separate the databases so you don't have to mess too much with keeping the browser environments and character encodings and database structure straight. So, please, ask us a question we can answer.

Sage Line 50 and importing into MySQL with ODBC

I am using MySQL-Front to do this. Anyone have any idea where i am going wrong or something to try. BTW Sage imports into excel just fine so MS products may be more forgiving ?

The Mysql manual explain how to rotate from a `hostnmae`-bin`.002 (or 001) file, but what about if the binlog is always the same? I could do a FLUSH MASTER in the master and then FLUSH SLAVE in the slaves, it wouldn't loose the sync? Regards When a slave crashes or reboots, it should start replicating from where it left off--at least ours do work that way. The current replication state is saved in master.info on the slave and when it starts up again, it should read that file and resume reading the binlog on the master where it left off. The master.info file contains the binlog#, location, user, password, etc... neccessary to restart replication. In you case, does the slave give you any error messages in it's error log about why it couldn't resume replication? If it doesn't try to start replication, have you tried doing a 'slave start' on the slave after it reboots? -Marc -- Davide Giunchi.

Difficulties between OS versions
Two of my co-workers attended the MySQL training in San Francisco last month. We have successfully installed 4.01 on a SUN Ultra 250 running Solaris 2.8. Four myisam tables were created and populated. When we tried to install the same software on a SUN Sparc 20 running Solaris 2.6 errors were encountered. Something about a missing file 'librt.so.1'. We thought the OS version was 2.7. Not correct! I downloaded the binary MySQL version 3.22.32 from the archive area on the website and it installed. However, the same 4 tables that are working under Solaris 2.8 are presenting errors under Solaris 2.6. The error message states that there is no field information available for any of the 4 tables. Am I doing something wrong. Next, does this older version have INNODB support available?

Re: Char vs Varchar field types
[EMAIL PROTECTED] wrote: When is it appropriate to use Char instead of Varchar and vice versa? Use char when you expect the length of the field to always be the same. Use varchar when you're not sure. Basically, when you're using varchar you're assigning a limit to the size of the string that can be put into the field, whereas with char you're saying that the string will always be exactly X characters long. So, for instance, it would be appropriate to store serial numbers as char, since most likely they will include alphabetical characters and will always be exactly the same length. And it would be more appropriate to store the name of the hardware component as a varchar, since that would be a different length for each record. Also: query, query, sql.

Hi Luke, When is it appropriate to use Char instead of Varchar and vice versa? Use CHAR for when you know in advance how many characters are going to be in that field. A good example is for MD5 hashes: they are always 32 characters long, so you can use CHAR(32). Use VARCHAR for when you don't know - names, addresses, etc. Cheers Jon mysql aol / - 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: Char vs Varchar field types
It depends on who you talk to and what you want to do. varchar will use less disk space, but char is faster to access (except for InnoDB tables, where varchar has the advantage). The benefit is using char is that the rows have a fixed length so MySQL knows exactly where each row starts and can find it easier when searching on an index. But, if you have just 1 dynamic field (like a varchar), then you might as well have them all varchars, because the row length is no longer fixed.

FW: Date and Mysql... (now complete)
(one should not mess up strg and shift :-/) Hi again... Hi, When I felt proud because last week I had asked about how to use NOW(), and get answer that got me working, but now I have a strange problem. It listing dates, but it not listing like it should, when the web page is create it going 9, 8, 5, 10 on the dates. Here is the SQL statement I am using... SELECT DATE_FORMAT(DATE, '%M %D, %Y') AS DATE, Title, Links, Summary FROM news WHERE TO_DAYS(NOW()) - TO_DAYS(DATE) =5 ORDER BY DATE DESC Date_format returns a string, so 10 is indeed below 5. You could try something like SELECT DATE, DATE_FORMAT(DATE, '%M %D, %Y') AS DATE2, Title, Links, Summary FROM news WHERE TO_DAYS(NOW()) - TO_DAYS(DATE) =5 ORDER BY DATE DESC Another problem I am having with another statement. The following statement should list birthdays that are 7 days out but it not... SELECT DATE_FORMAT(DOB, '%M %D, %Y') as DOB, Fname, Lname, Email FROM emply_info WHERE (TO_DAYS(DOB) - TO_DAYS(NOW())) =5 AND (TO_DAYS(DOB) = TO_DAYS(NOW())) and Tdate is NULL and DOB is not null ORDER BY DOB, Lname Similar thing. Date_format(NULL, '%M %D, %Y') should return 00 00, 00, iirc, and thus is not NULL even if your date column is. SELECT DOB, DATE_FORMAT(DOB, '%M %D, %Y') as DOB2, Fname, Lname, Email FROM emply_info WHERE (TO_DAYS(DOB) - TO_DAYS(NOW())) =5 AND (TO_DAYS(DOB) = TO_DAYS(NOW())) and Tdate is NULL and DOB is not null ORDER BY DOB, Lname Any clue why my SQL statement worked once are now not working?

mysqldump doesn't write data on subsequent calls (MySql 4.0.1)

Re: Date and Mysql...
»Chuck PUP Payne« sagte am 2002-04-10 um 10:27:19 -0400 : going 9, 8, 5, 10 on the dates. Here is the SQL statement I am using... That's because your DATE which you've made with DATE_FORMAT is treated as string. To fix it, I'd write: SELECT DATE_FORMAT(DATE, '%M %D, %Y') AS DATE, Title, Links, Summary FROM news WHERE TO_DAYS(NOW()) - TO_DAYS(DATE) =5 ORDER BY DATE DESC SELECT DATE_FORMAT(DATE, '%M %D, %Y') AS DATE_DSP, DATE, Title, Links, Summary FROM news WHERE TO_DAYS(NOW()) - TO_DAYS(DATE) =5 ORDER BY DATE DESC This way, you can display the nicely formated date in DATE_DSP and still got a good copy of date around.

Deleting Duplicated Records
I am new to MySQL and I have a test database that I am playing with. Through an accident while playing around, I ended up with two identicle records in the database. I did a filter to try and change just one of them but both would come up, so I couldn't see how I was supposed to delete just one of the two records. In the end, I deleted both records and re-input the one I needed but I know that there must be a better way of doing this. Perhaps having a column in my database with a serialized, unique record number would be a way to prevent this in the future?

RE: Deleting Duplicated Records
You are 100% correct. Since MySQL does not support cursors, I always put an auto_increment column in my tables for just this purpose. (This is what other DBMS' do, they just do it behind your back) Unfortunately, the way MySQL really handles result sets doesn't lend itself to simply adding a hidden auto_increment field to each row to act as a cursor and allow updating of rows in result sets. If it did, then I'm sure they would have put cursor support in the product already.

Re: Problem with mysqldump when using query caching
Hi Nick, I am seeing some rather strange problem here with mysqldump, after trying very hard to reproduce the problem on a test server, I gave up. Do the options make any difference when you run it? Can you send a trace of the actual dump? I was seeing mysqldump terminate in my case, now it just seems to loop, and I am not sure why the behavior changed. If we could reproduce this reliably maybe we could get a fix! Can you do this everytime?

Mysql and Quoted Identifiers
Hi,
I'm using MySQL version 3.23.37 which works fine. However I am
currently trying to convert a MS Access database to MySQL and some of
the column names have embedded spaces i.e. First Name. Now according
to the manual MySQL supports quoting of identifiers (for the above
reason), I cannot get it to work though.
MySQL is installed on Linux, and if I try to enter the following create
table statement to the MySQL client, it objects to the first quote
(either double or single quotes).
CREATE TABLE TEST ('ID' INTEGER);
while
CREATE TABLE TEST (ID INTEGER);
works as expected.
I must be doing something stupid :), but I can't see it.

Re: slow to a crawl
Hi. Well, your are right, indexes are not used at all, so ignore everything about key_buffer and indexes I said, regarding this issue (but key_buffer=16MG seems small with 1GB anyhow ;-) Depending on how often you need the query, and how much columns are involved, you may want to consider to add a key over all involved columns, which would avoid reading the data file, but read the smaller key only, instead (if it's not clear why that would help, see the EXPLAIN link below and search for the explanation of using index). Hm. From vmstat output it looks like the second query is disk-bound on writing. Most probably writing temporary table(s) as EXPLAIN tells so (compare http://www.mysql.com/doc/E/X/EXPLAIN.html). http://www.mysql.com/doc/T/e/Temporary_files.html tells, for sorting in GROUP BY, the maximum needed disk space is: (length of what is sorted + sizeof(database pointer)) * number of matched rows * 2 So if the first query needs about 5MB (~31000 rows), the second one needs about 30 times of that, namely 150MB (~100 rows). If your columns are larger (I presumed about 20 bytes above), it gets worse. From the vmstat output I guess this is rather ~25MB resp. ~650MB for your case (of course, that is only a very rough guess). tmp_table_size determines the maximum size of an in-memory temporary table. If a table gets bigger, it automatically converts it to a disk table. I don't know whether the sorting table for GROUP BY qualifies for an in-memory table, but how about setting (at least temporarily) tmp_table_size to a real huge value (say 500MB) and re-run the queries and look at the vmstat output. bo should be real small at least for the first query, if in-memory tables are used. Well, to sum up: Your first query mainly seems to be bound on disk read speed (your table is about 1GB?). The second one needs a much larger tmp table (which it also has to sort!) and trashes your disk, that's probably why the machine feels unresponsive. For now, I have no further ideas than playing with tmp_table_size and trying to use an index over all column. Anybody else? Bye, Benjamin.

Re: Mysql and Quoted Identifiers
Hi.
You have to use backticks (`) instead of single quotes (') as in
CREATE TABLE TEST (`ID` INTEGER)
When MySQL has been started with --ansi, double quotes () will have
the same meaning. See http://www.mysql.com/doc/L/e/Legal_names.html
for more info.
Bye,
Benjamin.

Can I just do a select statement in phpmyadmin to pull up these addresses? And, how should it read?

Re: select query optimization
Hi. As I said, or at least, tried to say, a key over all used columns should help. Adding the column from ORDER BY avoids the using filesort. Adding YIADDR (which I simply overlooked last time) should add using index, as I mentioned. This means, that the data file is not touched at all, but only the index file. I.e. INDEX ( POOL, STATE, TIME_STAMP, YIADDR ) Of course you have to pay off a bit with disk usage and insert speed. But if select speed is that important, that's usually a good trade off. Bye, Benjamin.

Hi, We are developing a webbased serch application on MYSQL and PHP. I am sure most of you must have already implemented such application. Could you share with me the logic of such application. We were planning to keep a keyword search and my people feel that that will require additional load of keeping track of keyword and they are not interested in that. The other option is fulltext serch on all the data for one table, but concern about of the performance issue. Wondering how you guys are doing out there ? Which is the best way ?

RE: -- e-shop
Hi We are in the process of developing Ultra High Availability ecommerce sites based on php and MySql. 1. The software itself is well tested 2. The site is duplicated on two or more servers in separate data centres, with live replication. 3. Nameservers for the domain are on the same servers as the site. 4. Primary and Secondary nameservers are under a different domain 4. Nameserver refresh times are short. If there is a server or network failure the whole site, including DNS, fails, so the browser looks to the secondary (backup) site. In theory only simultaneous failure of both servers will stop the site being available. A DoS attack aimed at the domain itself could also bring it down. The live replication is the hardest bit, but it all looks OK. We are testing at the moment but are hoping for 100% uptime or very close.

Many thanks for any assistance: I have data (classified ads) in a text file that I would like to load into a table. The problem is that, as classifieds, they are broken down by class and sub-class. For instance: 0031 - Announcements - Notices One ad Two ad - Tickets Three ad Four ad Five ad 0035 - Help Wanted - Professional Six ad Seven ad - Dishwashers Eight ad And so on. The problem I have is how can I indicate in the load data infile that '0031 - Announcements' is a class and to assume everything below it flow into the database (not putting anything in the 'class' field or repeating the same class in the class field) until the next class is reached. The same would be the case for the sub-class, with numerous ads under a sub-class. Does this require a separate table for each class? Or should there just be more preparation of the text file to make it conform? Point me toward something similar someone else has done and I'll pursue it. for filter: MySql, database, query, Mephistopheles -- Greg Peretti web developer www.abqjournal.com (505) 823-3888 --- The web of our life is of a mingled yarn, good and ill together. - William Shakespeare The more I know, the less I understand. - Don Henley - 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?

search pattern matching
In MySQL it says that adding the following to a where clause: like %$somestring%; should select matches that contain $somestring in them anywhere. However when I use it I find that if e.g. I have an entry dog in the database, if I search for dogs, it doesn't come up. Also if I search for dog house it doesn't come up. How come?

Innobase UPDATE ... LIMIT x;
Does anyone know how Innobase would handle this query? If it would lock all of the rows within the table, or attempt to find all of the rows within the table instead of just finding the first X in my LIMIT and locking those and updating those? I have a table with 1 million rows as my example WHERE c1 is equal to 5 (c1 = 5) and when I run this query, it takes roughly 16 seconds, which it should not because of the index: UPDATE t1 SET c1 = 1 WHERE c1 = 5 LIMIT 5; This should go rather fast, because SELECT * from t1 WHERE c1 = 5 LIMIT 5 returns the 5 rows in 0.x seconds, however when I update it takes an extended period of time. Creation Statement: CREATE TABLE `t1` ( `id` int(11) unsigned NOT NULL default '0', `c1` tinyint(3) unsigned NOT NULL default '0', PRIMARY KEY (`id`), KEY `c1` (`c1`) ) TYPE=InnoDB Example select mysql select id, c1 from t1 where c1 = 5 limit 5; +--+-+ | id | c1 | +--+-+ | 1433 | 5 | | 1434 | 5 | | 1435 | 5 | | 1436 | 5 | | 1437 | 5 | +--+-+ 5 rows in set (0.00 sec) Example update: mysql update t1 set c1 = 1 where c1 = 5 LIMIT 5; Query OK, 5 rows affected (15.69 sec) Rows matched: 5 Changed: 5 Warnings: 0 Example count: mysql select count(*) from t1; +--+ | count(*) | +--+ | 100 | +--+ 1 row in set (0.90 sec) Version: mysql show variables like 'version'; +---+--+ | Variable_name | Value| +---+--+ | version | 3.23.49a-max | +---+--+ 1 row in set (0.01 sec) database, mysql, query, update, select, filter nickg - 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?

Could you share with me the logic of such application. We were planning to keep a keyword search and my people feel that that will require additional load of keeping track of keyword and they are not interested in that. The other option is fulltext serch on all the data for one table, but concern about of the performance issue. Wondering how you guys are doing out there ? Which is the best way ? Any suggesstion appreciated . We need some more details to provide meaningful assistance. That having been said, if you're going to be doing a project with massive amounts of text and want to provide full text searching capabilities, definitely take a look at MySQL v4 which provides some great enhancements along the lines of full text indexing/searching. Indexing is purportedly 100x faster and full text searching is purportedly 2x faster. There's also a wealth of new search operators planned (I don't know yet it they're implemented) which help with defining the search.

Re: search pattern matching
You are searching for the word dogs...that word is not contained in the word 'dog' or the phrase 'dog house.' If you searched for '%dog%' you would get both of those results. The wildcard character allows any other character in it's place...hence '%dog%' finds 'mydog', 'mydogs', etc, etc...it does not lop of part of your search word in the effort to find something else. -- Jason On Wed, 2002-04-10 at 17:58, Scott wrote: In MySQL it says that adding the following to a where clause: like %$somestring%; should select matches that contain $somestring in them anywhere.
