Re: increasing InnoDB search performance
Eric, Eric Mayers wrote in message ... I have an application that stores a large (up to 6gb) database in an InnoDB table. I'm using an InnoDB table to have concurrent inserts and selects and to get beyond the 2gb limitation. I have to allow read-only remote database connections and cannot enforce that users use any kind of special query to access the database (e.g., implementing my own fulltext-like index and using the index at an application layer). The content consists of log entries which are each under 255 characters long. use the VARCHAR type instead of CHAR type. Otherwise your columns will take a full fixed length of space and the table will be bigger and slower. I'd like to know what I can do to improve the response time of the database under these restrictions. So I have a few questions: Would adding ram help? I can't imagine that an operation that requires searching 6gb (a disk bandwidth or processing bottleneck problem) would be improved much by adding ram.. ? If every query needs to scan the whole 6 GB table, or access it totally at random, then adding RAM does not help. But usually queries have a restricted working set, and a much smaller buffer pool can serve most queries quickly. Adding RAM and incresing the buffer pool size helps in most cases. Can I do anything (short of hardware changes) to increase performance? The usual way is to use EXPLAIN SELECT, and in very problematic cases use the STRAIGHT JOIN and USE INDEX (index1, index2, ...) clauses of MySQL to force a query plan. The MySQL 'slow query log' can be used to track slow queries. The Unix 'top' and the Windows Task Manager are the best way to determine if the load is CPU-bound or I/O-bound. innodb_monitor prints very detailed statistics on the internal working of InnoDB, and you can also innodb_lock_monitor to track lock waits, if they are a problem. And long term question: I've noticed that a fulltext index feature doesn't appear on the InnoDB todo list. From my (limited) research, it looks like this is a feature a lot of people would find very useful. Is this a long term goal, or has it been excluded for some reason? There has been demand of a fulltext indexing capacity on InnoDB type tables. If there are enough paying customers requesting it, we can assign a developer to port the MyISAM fulltext search on InnoDB. Fulltext indexes will work also on a transactional database.

Re: mysql create table error
Hi! You have not created an index on your foreign key. From http://www.innodb.com/ibman.html : ... An example: CREATE TABLE parent(id INT NOT NULL, PRIMARY KEY (id)) TYPE=INNODB; CREATE TABLE child(id INT, parent_id INT, INDEX par_ind (parent_id), FOREIGN KEY (parent_id) REFERENCES parent(id)) TYPE=INNODB; Both tables have to be InnoDB type and there must be an index where the foreign key and the referenced key are listed as the first columns. InnoDB does not auto-create indexes on foreign keys or referenced keys: you have to create them explicitly. If MySQL gives the error number 1005 from a CREATE TABLE statement, and the error message string refers to errno 150, then the table creation failed because a foreign key constraint was not correctly formed. .

RE: performance help required. (2G - 4G Ram upgrade)
Hi, We use Red Hat Linux release 7.1 (Seawolf) Kernel 2.4.3 on a 2-processor i686 Only around 5000 of the rows match out of the 58,000,000. As I understand it, we do have single indexes on each of the columns. Given the replies below, I feel that mysql is not getting the optimisation correct. Do I need to analyse the key distribution or something to give MySQL more up to date information. If so, can I do that without locking the table / taking the database down? When I use USE INDEX(log_id_idx) it still ignores me and does what it wants. Is that right?

RE: Programming with C API question
Hi, all MySQL team Thanks for your former help. Here is another question: As MySQL support multiple instances, each instance will run with different socket file and tcp/unix port number. I want to know when using MySQL client programs like mysqladmin to connect different instances, are both socket file and port number parameter necessary(without any Option file)? For example: we have 2 instances running on one machine Instance West runs with /var/lib/mysql/west.sock and port: 3307 Instance East runs with /var/lib/mysql/east.sock and port: 3308 So if we want to connect to instance East using mysqladmin, is following safety enough (not specify port number)? /usr/bin/mysqladmin -u root -p -S /var/lib/mysql/east.sock status In addition, how about with C API like mysql_real_connect()?

BEGIN/COMMIT statements not written to the binary log : may it cause problems with replication ?
Hello there, I use MySQL (4.0.1) with InnoDB tables with binary logging on. I see that the BEGIN and COMMIT statements that wrap my queries are not written to the binary log. I perfectly understand this if I have one server. But assume I have a master server, and a slave server that replicates the master. Let's say I distribute reads. Let's say I issue the following queries on the master (I use BEGIN and COMMIT for consistency) : BEGIN; update accounts set sum=sum-100 where num=10; update accounts set sum=sum+100 where num=12; # I don't work in a bank !! COMMIT; then only update accounts set sum=sum-100 where num=10; update accounts set sum=sum+100 where num=12; is written to the master's binary log, and then propagates to the slave. Assume that, while it is propagating I issue a reading query on the slave : select sum from accounts where num in(10,12); Then, to my mind, this select might be treated AFTER the first update being processed by the slave, and BEFORE the second update being processed by the slave. Then I'll get not-consistent results. This would not happen if BEGIN and COMMIT had been written to the master's binary log. Does anyone here agree or am I misunderstanding anything ? If this problem really exists, is it to be fixed ? Thanks !

I'm shure there are much better ways to do this, because this only applies when your field has a prefix of only one character and when you know the upper limit of the integer part of the field.

RE: transaction
Yes MySQL supports transaction. But you have to use certain table types : for example InnoDB or BDB (and not MyISAM). I use InnoDB ; read the following section of the manual : http://www.mysql.com/documentation/mysql/bychapter/manual_Table_types.html#I nnoDB it will tell you which options you may have to set in your my.cnf or my.ini file. After that, you will have BEGIN/COMMIT/ROLLBACK, automatic crash recovery, etc. Guilhem -Message d'origine- De : Felik Harmanto [mailto:[EMAIL PROTECTED]] Envoye : mardi 5 fevrier 2002 12:10 A : [EMAIL PROTECTED] Objet : transaction hi, is mysql support transaction? how to setup it? please help thx felik __ Do You Yahoo!?

PHP and pconnect
Hi The I have noticed that the number of Aborted Clients and Aborted Connections has increased sharply recently on our two production servers, but not on our development server. Yesterday we started getting a number of blocked host errors, which we had to clear up with flush hosts. http://www.mysql.com/doc/B/l/Blocked_host.html This morining, I increased the max_connect_errors from 10 to 1, and the problem has thankfully disappeared. I know that this hides the problem, but I am at a loss to explain the cause. The favourite causes are - use of mysql_pconnect (introduced in Novemeber) - use of fsockopen($Primary, 3306, $errno,$errstr,5) (closed by fclose()) to test if connection possible before attempting connection (introduced last week) - much high web activity causing recycling of httpd processes mysql_pconnect was used to improve performance, and reduce load -- it works fsockopen is used to determine if the web process should use the local, or remote database. Can anyone shed any light on the causes of Aborted Clients and Connects, and whether mysql_pconnect and fsockopen would have an effect ?

insert into.. select from mult. tables
Hello, I'm relatively new to mysql and I've come across a problem while trying to insert values from multiple tables into a single, existing table. Here's the syntax that I'm using: insert into table1 (col1,col2,col3,col4) select Foo.col1, Foo.col2, Bar.col3, Bunk.col4 from table2 as Foo, table3 as Bar, table4 as Bunk where Foo.col1 = 5 and Bar.col1 = 5 and Bunk.col1 = 5; This works fine so long as the where clause is true. Now here's my problem: I used AND in the above example however, what I want is for each expression to be evaluated individually, like an OR that will not stop if the first expression is true. So, each of the source tables may or may not satisfy the condition, if they do, then the proper value is inserted into table1, if they do not, then some default value should be inserted into table1 (null). This is an if / else problem but I don't know if mysql supports anything of the sort or if I need to use some sort of script to work around this prolem. Any advice would be greatly appreciated. Thanks.

I'd guess your fsockopen calls are causing Aborted Clients to rise. If you still have problems after fixing that, then my first idea would be that PHP does not clean up properly when a client aborts the page by pressing the stop button. This would be rather easy to test. If you're using Apache, you can also try setting MaxRequestsPerChild to something like 1, so that after a while the process will die and hopefully close any open connections to the MySQL server. Or if you're already doing this, try disabling it and seeing if it helps. - 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?

Table join question
Hi, I'm trying to build a query to solve a fairly simple problem. I have two tables (A and B) linked by a common ID. I want to locate a specific record in A that is linked to two or more records in B based on second field in B matching certain criteria. I've tried every type of inner, outer, left, and right join to accomplish this, but can't come up with anything that works. EG: Select * from A inner join B on A.ID=B.ID where B.Val='25' and B.Val='35'; This will rturn zero matching records since B.Val can't equal 25 and 35 at the same time. If I substitute and with or, I will get multiple records from A that are linked to either 25 or 25. I just want the one record that is linked to both 25 AND 35. Thanks for any help.

Using SQL in a C Program
Most of my experience with SQL comes from an SQL environment in which the program will run through and end fairly quickly. I'm now up against a constantly running C program which utilizes the database on a regular basis. In this case, is it better practice to only open the connection for the duration of use, or have it open constantly and run a check to reconnect if it dies for some reason?

Re: Using SQL in a C Program
Whoops! Forgive me, I meant to say a CGI environment.

Re: Sql gurus
Hi Peter, I am working on a search logging script to count the most popular word or phrases searched for. Table I could add a line for each search, and aggregate the results for reports, but I was wondering about the following which would keep table sizes down. | search word | count | = | Nuts |125 | | Bolts|119 | | Screws |110 | | Washers | 98 | If the word is already in the table increment the counter, if not add the word and set counter to 1 query 1 = update counter where word = search word if no records updated query 2 = insert word and set counter to 1 Is there a single query that will do this or does it have to be 2?

Memory limit issue with 64 bit mysql.3.23.46
We are running an extremely large instance of mysql version 3.23.46 on Solaris 2.8. We are attempting to use a software version compiled 64 bit and have been experiencing memory related server crashes. The behavior suggests that we are still unable to use more than 4G of memory. If the server is started with the following settings: key_buffer=4608M max_allowed_packet=1M table_cache=1024 record_buffer=1M sort_buffer=1M thread_cache=12 thread_concurrency=12 myisam_sort_buffer_size=512M We observe the following symptoms / problems: (1) A mysqladmin variables call shows that the key_buffer is set to be 1 G, not 4.5G. (2) Under any sort of database load, the server crashes with the following error output: mysql got signal 10; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=4831834112 record_buffer=1044480 sort_buffer=1048568 max_used_connections=0 max_connections=512 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 5765112 K bytes of memory Hope that's okay, if not, decrease some variables in the equation. If the server is started with more modest settings (e.g., key_buffer_size=2G), mysql operates correctly. Additionally, mysqladmin variables shows a correct key_buffer value. System memory is not a constraint ( 6 G real memory and 14.5 G swap). - 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: PHP - MySQL - SQL7 Server - Visual Basic.
Bob, I've posted this back onto the list because there are others here who will be much more able to assist. Clarification: I currently have 22 NT workstation that send data to various tables in a SQL7 database running on a NT sever. The visual basic front end organizes this data in to a neat fashion and allows the user to graph and print data and comparisons from the various tables. The front end also responds to e-mail requests for information from the tables. Currently there are only 12 authorized e-mail accounts so it is easy to manage. We are now going to add about 100 workstations, More tables and 200 authorized e-mails accounts. With this addition I have decided to eliminate the e-mail accounts and post all of this information to a secure web server that I will administer. So what I need to do is have a VB program write this data to a MySql database that will only allow users to view the data. I have extensive VB experience and have created and updated many types of databases using it, however I have never used MySql and need some pointers. Can Vb create and write to MySql databases? =yes, using an ODBC or ADO interface. What syntax do I use in PHP to read the MySql database? =PHP has a wide range of interface functions 'built-in'. =Why use two RDBMS'?

Re: deleting var=0.1
On 5 Feb 2002, at 15:11, Dan Nelson wrote: I assume var1 is a float in the first case? Due to rounding issues, the = operator will almost never work on fractions. Use the primary key to select which record to delete, or use a number range (var1 BETWEEN 1000.009 AND 1000.1001). Matthias Hoffmann should also consider whether FLOAT is the right type. The fact that he's trying to see whether the value is exactly equal to 1000.1 suggests that it's not, since floats aren't good for storing exact values. If the column represents some sort of code, then a string type (like VARCHAR) is probably what he wants. If it's a currency amount, then an integer type stored as the smallest unit (cents, for example) will work much better. Fodder for the idiotic filter: sql,query -- Keith C.

Re: Set up help needed
If you want to get the most out of MySQL, then you really need to learn to use the command line tools. MySQL has the easiest to use tools and language of any database I've used. SQL allows you to do really powerful things easily. Download the Windows version and install it. You can use the mysql client to connect to the remote server from your Windows box. Alternatively, and probably even easier, download an SSH client for Windows (do a Google search for putty) and SSH in to your Linux box. Then use the mysql client locally there. For long SQL queries like creating tables, I find it useful to type them up in Notepad and then paste them into the client. If you made a mistake, fix it in Notepad and paste it again. mysqldump is also a very handy tool for viewing a table's schema.

making arrays while GROUP-ing
Hi list,
I'd like to generate arrays into a field for the result-set
by means of grouping...
myTable ( MySQL 3.23.33 / MyISAM table )
++--+
| id| type |
++--+
| 002 | 'CD' |
| 002 | 'LP' |
| 011 |'DVD' |
| 081 | 'CD' |
| 081 | 'LP' |
| 081 |'DVD' |
| 087 | 'MC' |
| 087 | 'LP' |
++--+
myWish
*** SELECT id, makeArray(type) FROM myTable GROUP BY id;
++---+
| id| ? makeArray(type) |
++---+
| 002 | ('CD','LP') |
| 011 | ('DVD') |
| 081 | ('CD','LP','DVD') |
| 087 | ('MC','LP') |
++---+
I know, when GROUPing, you can ask for a COUNT like:
*** SELECT id, COUNT(*) FROM myTable GROUP BY id;
++--+
| id| COUNT(*) |
++--+
| 002 |2 |
| 011 |1 |
| 081 |3 |
| 087 |2 |
++--+
How should I tackle this ?
Thanks !
Best Regards,
Bart

Having in the Linux server the privileges, from the NT workstation you can connect using the mysql.exe client using the parameters of user, host and password.

MySQL 4.0.1 bug ... no returned results using GROUP and ORDER

Re: PHP - MySQL - SQL7 Server - Visual Basic.
Hi bob, I have do everything you need but may be a little diff. I have MS SQL 6.5 on NT, MySQL 3.23.47 on Linux and using PHP / VB 6 for client. The first thing you must define some role of usage and other, how to manipulate your data. I have PHP update routing in some project (transfer via ftp function, read along text file and then update data to MySQL). If you need to access to MS SQL via PHP try to use FreeTDS on Linux (may be they have copy on NT). All you need about MySQL are on the Web. If you need to access MySQL via VB: try to use MyVBQL at www.icarz.com/mysql/. MyVBQL using libmysql.dll to access MySQL and let you used recordset style in your application.

Clarification: I currently have 22 NT workstation that send data to various tables in a SQL7 database running on a NT sever.

The front end also responds to e-mail requests for information from the tables. Currently there are only 12 authorized e-mail accounts so it is easy to manage.

compression
Hi, I need to know that MySQL has any compression method when it store data? If the answer is Yes, How the different compression between MySQL and other tools (zip, gzip)? I asked this question because I need to store some text file for future used (at least 1 Mbyte per day). I was used Winzip in Windows to compress and keep in file server. If MySQL could compress some byte of data I think it better than flat file.

RE: Obtaining GMT time in mySQL
My apologies, what I said in this previous post is incorrect. It appeared as if the time was UTC (except for daylight savings) to me, but it was mearly because of the format string As Paul DuBois quite rightly pointed out is that %h in select FROM_UNIXTIME(UNIX_TIMESTAMP(), '%Y %D %M %h:%i:%s %x'); returns the hour in 12hour format, I assumed it was in 24hour format which makes it appear close to UTC in my timezone. Thus select FROM_UNIXTIME(UNIX_TIMESTAMP(), '%Y %D %M %h:%i:%s %x'); does not return GMT time but local time. At 02:13 PM 5/02/2002 +1100, Oliver Mannion wrote: I am close to a solution: select FROM_UNIXTIME(UNIX_TIMESTAMP(), '%Y %D %M %h:%i:%s %x'); UNIX_TIMESTAMP() returns the number of seconds since '1970-01-01 00:00:00' GMT Convert this to a date format and you have a GMT date. Thanks to Chris Land for pointing the UNIX_TIMESTAMP() function out to me. The only prob is daylight savings. We in NSW, Australia are currently in daylight savings and the date returned doesn't accomodate for that. Any one have any ideas why?
