Re: newbie: how to sort a database without extracting the data
MY first guess is that you simply need an ORDER BY field in yout (later, ad you put it) SELECT. However, the whole point of using a database such as MySQL is that you do not worry about how exactly your data is stored. there are many different tricks that a database can use to optimise both storage and retrieval, and it is the job of a good DBMS to implement as many of them as it can, and select the appropriate tricks to optimise your queries. However, in order to do this, you have to give it some hints, and the way you do this is by telling it to build indexes based on the fields which you intend to use for SLECTing data or for ORDERing, This allows the database to search un-ordered data in an ordered manner. The database automatically and invisibly maintains an index, or several indexes, on your data as you add and remove records. Once you have created the index, you need take no further action It sounds as if your field should be give a special kind of index called a PRIMARY KEY. This allows the database to ensure that entries ar unique, and to retrieve data very fast when selec ted or ordered by that column. You should search the MySQL manual (and poosibly the net) for PRIMARY KEY. I think you had the idea oc actually sorting the data in the file. This would be horrendously slow: basically, it would ahve to shuffle on average half the records in the database every time you did an insert or delete. You say that you don't want to sort the records during SELECT. But to do exactly this is what databases are designed to do: to accept data essentially randomy, build and maintain indexes on that data, and use those indexes at SELECT to produce a finely crafted subset of your data.

Re: Slow queries, why?
Hello. We're running MySQL 4.11 on a machine with 2GB memory, the table is InnoDB with a compound primary key, and additional indexes on all rows with searchable options in the API. Any generic advice or admin tools would be great. Use EXPLAIN to determine how efficient your indexes are. Using a lot of keys could slow down the INSERT operations but fasten the SELECTs. InnoDB monitors might be helpful in your case as well.

Re: Tables lost in new location of database
Hello. Are you sure that you are running mysqld-max (mysqld-max-nt)? Are you able to select data from invisible tables? Is it possible that you have disabled symlinks? Does the problem remain with 4.1.11 version? I use mysql 4.0.23-nt on win XP. In order to shift some of my databases I followed the following steps as per a recent post: 1. I moved the folders containing the database files that I wanted to move to a new folder (from data to data2) after stopping mysql of course. 2. In the data folder I created a file named with the database (same as the folder names that I moved) prefixed with .sym. 3. Inside each of these .sym files I enterred (typed) in the exact path of the new folders and nothing else. 4. Restarted mysql Now when I give show databases; at the mysql prompt, all my database names are displayed including the ones I moved. Here is the issue: When I use one of the databases that I had moved and give: show tables I am getting an empty set. I know the data is there because the size of the .myd files is 50 MB - well none of the .myi or .frm file is missing or empty! Also I noticed that the .sym files have numbers auto-enterred before the file path I had specified - I guess it is in running mode. So how do I see my tables on the moved databases and query on them??

This system is a dual proc with 4GB ram and over 500GB on a RAID 5 setup I found super-smack (which tests 100% what I want), but the problem now is that it does not compile on FreeBSD, and the few (literally not even 3) linux boxes we have cannot handle the load to stress our DB server to the max. This I know because iostat on the FreeBSD DB Server shows that the entire box is virtually idle (the load averages confirms) while the tests on super-smack run.

Hi! thanks for your response. This are the values of the variables you asked for: collation_connection: utf8_general_ci collation_database: utf8_general_ci collation_server: utf8_general_ci character_set_client: utf8 character_set_connection: utf8 character_set_database: utf8 character_set_results: NULL character_set_server: utf8 character_set_system: utf8 These were taken from a query inside the app. From the query browser the only difference is: character_set_results: utf8 Anyway, the same query has the same results in the app and the query browser.

I moved the folders containing the database files that I wanted to move to a new folder (from data to data2) after stopping mysql of course. 2. In the data folder I created a file named with the database (same as the folder names that I moved) prefixed with .sym. 3. Inside each of these .sym files I enterred (typed) in the exact path of the new folders and nothing else. 4. Restarted mysql Now when I give show databases; at the mysql prompt, all my database names are displayed including the ones I moved. Here is the issue: When I use one of the databases that I had moved and give: show tables I am getting an empty set. I know the data is there because the size of the .myd files is 50 MB - well none of the .myi or .frm file is missing or empty! Also I noticed that the .sym files have numbers auto-enterred before the file path I had specified - I guess it is in running mode.

Suggestions to retrieve surviving data
Hello all, I have a problem on a development machine that somehow got every single mysql program in the /usr/bin directory wiped out (which looks like it was everthing but mysqld). The server is actually up and running, and the datadir is intact, so it looks like my data is okay. However, I had this set up only with users from localhost, so I can't connect from a client on another machine. It's like I'm trying to reach an island but I don't have a boat. I have an older backup, but would like to try and save the current data. It's not at all critical, so I don't want to go to too much bother - it's just a convenience thing. I only have 4 important MYISAM tables, so my plan is: 1. Shut down server 2. Back up datadir 3. Install MySQL-server and MySQL-client 4. Restore backup to datadir I'm installing same version over the old from RPM, and planning to just -force the install. My second thought was I could try just forcing the install of client and mysqldump-ing the data before reinstalling the server, which I'm thinking is probably the better way to go. Am I missing any issues or a better way to do this? Thanks, kgt -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

In order to shift some of my databases I followed the following steps as per a recent post: 1. I moved the folders containing the database files that I wanted to move to a new folder (from data to data2) after stopping mysql of course. 2. In the data folder I created a file named with the database (same as the folder names that I moved) prefixed with .sym. 3. Inside each of these .sym files I enterred (typed) in the exact path of the new folders and nothing else. 4. Restarted mysql Now when I give show databases; at the mysql prompt, all my database names are displayed including the ones I moved. Here is the issue: When I use one of the databases that I had moved and give: show tables I am getting an empty set. I know the data is there because the size of the .myd files is 50 MB - well none of the .myi or .frm file is missing or empty! Also I noticed that the .sym files have numbers auto-enterred before the file path I had specified - I guess it is in running mode. So how do I see my tables on the moved databases and query on them??

Re: Slow queries, why?
Yes, indexes slow down inserts (or updates that change the value of a column that is indexed). Also, remember that MySQL only uses one index per per table in a query. So if there are some columns in your table that are indexed, but, 1) Have poor cardinality (number of distinct values - low cardinality means there aren't many distinct values) 2) Are only used in a where clause with another column that has good cardinality then they are an excellent candidate for removal. While EXPLAIN is great for queries, it won't help much with an insert; it might be useful for figuring out what indexes are used, and which ones aren't. Use show innodb status to get an idea of what's going on (Gleb suggested it in the link to the innodb monitor). You should also post the relevant parts of your my.cnf file; have you seen this equation before: Memory Used By MySQL = Innodb_buffer_pool_size + key_buffer_size + max_connections*(sort_buffer_size+read_buffer_size+binlog_cache_size) + max_connections*2MB Use it to calculate how much memory you are using. Finally, read up on phantom reads: http://sunsite.mff.cuni.cz/MIRRORS/ftp.mysql.com/doc/en/InnoDB_Next-key_locking.html This might be what's happening. David Gleb Paharenko wrote: Hello.

Re: Slow queries, why?
Thanks! Explain and InnoDB monitor were exactly what I needed to diagnose and fix the problem! In case you were curious, the issue was that the statement I was expecting to run was not the statement that was running, but the first hundred and some-odd characters in both were the same. Using the monitor I was able to see that the wrong thing was running. Some SELECTs are still taking longer than they should, but I have some new tools at my disposal, which makes me very happy. -- Joe On 5/4/05, Gleb Paharenko [EMAIL PROTECTED] wrote: Hello.

Unique Index on multiple columns that can contain NULL in MySQL
I'm getting lots of duplicate rows even though I have a unique index defined over multiple columns. The issue is that multiple NULL values are allowed, even when some values are not null. This could be as specified by the SQL standard, but it's certainly confusing for the developer. (By the way, one source of confusion is that phpMyEdit was disallowing duplicate values even though sql insert statements allowed them). Here's the test case: Goal: prevent duplicate rows on the (c1, c2) pair: CREATE TABLE `test_multi_column_null` ( `pk` INT NOT NULL AUTO_INCREMENT, `c1` VARCHAR( 30 ) , `c2` VARCHAR( 30 ) , PRIMARY KEY ( `pk` ) ); ALTER TABLE `test_multi_column_null` ADD UNIQUE `unique_index` ( `c1` , `c2` ); Unexpected works: INSERT INTO `test_multi_column_null` ( `pk` , `c1` , `c2` ) VALUES ( '', '1', NULL ), ( '', '1', NULL ); As expected, this causes a duplicate entry: INSERT INTO `test_multi_column_null` ( `pk` , `c1` , `c2` ) VALUES ( '', '1', '' ), ( '', '1', '' ); mysql select * from test_multi_column_null; ++--+--+ | pk | c1 | c2 | ++--+--+ | 1 | 1 | NULL | | 2 | 1 | NULL | | 3 | 1 | | ++--+--+ 3 rows in set (0.00 sec) Now, to drive the point home, let's add some null rows: INSERT INTO `test_multi_column_null` ( `pk` , `c1` , `c2` ) VALUES ( '', NULL , NULL ), ( '', NULL , NULL ); mysql select * from test_multi_column_null; ++--+--+ | pk | c1 | c2 | ++--+--+ | 1 | 1 | NULL | | 2 | 1 | NULL | | 3 | 1 | | | 4 | NULL | NULL | | 5 | NULL | NULL | ++--+--+ 5 rows in set (0.00 sec) Note: this works even with bdb engine in MySQL: mysql alter table test_multi_column_null engine = bdb; Query OK, 5 rows affected (0.03 sec) Records: 5 Duplicates: 0 Warnings: 0 mysql select * from test_multi_column_null; ++--+--+ | pk | c1 | c2 | ++--+--+ | 1 | 1 | NULL | | 2 | 1 | NULL | | 3 | 1 | | | 4 | NULL | NULL | | 5 | NULL | NULL | ++--+--+ 5 rows in set (0.00 sec) Conclusion: if you want to enforce uniqueness, don't use columns that allow NULL.
Re: Unique Index on multiple columns that can contain NULL in MySQL
I think you should review the very recent thread why NOT NULL in PRIMARY key?? which might shed some light on your particular issue. In a nutshell, NULL!=NULL, so the database engine can not detect the duplicate rows, as is expected. -Hank On 5/4/05, Dennis Fogg [EMAIL PROTECTED] wrote: I'm getting lots of duplicate rows even though I have a unique index defined over multiple columns. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
stability of mysql error strings
I have a unique key on username and email address in mysql. In my application logic, I want to test for that response on failed insert. Error number 1062 tells me there is a duplicate key, but no way to tell what key that is. The error string returned is more telling, but seems less than ideal to use for stability and upgrade issues. It tells me username is key 2 and email is key 3. So, if error_string ends with 'key 2' etc etc I took care to lowercase the error string, so that's covered. What is not, is that it may not always 'ends with', so I could move to 'contains'. Anyway, I think you see what my concern is, wonder what the preferred method to fix is, or if someone can tell me when, if ever, the error string has ever changed format in mysql. I could run a insert ahead of time and parse the returned results, but I would rather not add the overhead of another select ahead of time. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Beta 5.0.4: Table 'mysql.host' Does Not Exist
When I installed MySQL-server version 5.0.4 on my Fedora Core 3 system (Linux x86, using RPMs from MySQL.com) with SELinux running in enforcing mode, the server failed to start, possibly due to denials from the SELinux implementation. 'restorecon -R -v /var/lib/mysql' failed to let the server start. 'restorecon -R -v /usr/lib/mysql' failed to let the server start. 'restorecon -v /usr/sbin/mysqld' failed to let the server start. I then disabled SELinux just for the mysqld application. However MySQL 5's server won't start. I located the error log and it has this message: [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist How can I fix this problem? Should I uninstall MySQL (with 'rpm -e') and reinstall it? This should work if I disabled SELinux for mysqld?

Problem connecting to 4.1 server
I am have trouble connecting to the MySQL server 4.1 using the API, though I have no trouble connecting using the same parameters from the command line mysql.exe. I'm using server version 4.1.10 on Windows Server 2003, which was started with --old-password (to ensure back compatibility with legacy PHP 4 applications). As a result my mysql server uses the older style, 16-bit password hashing. I'm using mysql_real_connect, and linking with the libmysql.lib that ships with ver 4.1.10. When I connect using mysql_real_connect() to a database with a password, it fails, and returns a bad handshake error. However, when I connect using mysql_real_connect() to a database with no password, it connects without a problem. This makes me suspect that the client is incorrectly trying to hash with the newer style 41-bit hashing, against a server using the 16-bit hashing. Is there any way to tell the client to use older-style hashing? One of the client flags seems to relate to this, ie: #define CLIENT_LONG_PASSWORD 1 /* New more secure passwords */ (mysql_com.h, line 107) but this should mean that a value of 0 uses short passwords, and I'm calling mysql_real_connect with a value of 0 for the client flag argument (though I've also tried with 1 to see if that works). I have no trouble connecting to the database using the same connection parameters using the command line mysql.exe. Do anyone have any idea what I should do? *** code extract *** MYSQL my; mysql_init(my); if (!mysql_real_connect(my, host, user, password, db, port, NULL, 0)) { cerr ... exit(EXIT_FAILURE); } else { cerr ... exit(EXIT_SUCCESS); } -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
