The MySQL Connectors team at Oracle == Changes in MySQL Connector/ODBC 5.2.6 Functionality Added or Changed * Added a lock in the ENV structure against simultaneous accesses to an environment handle's connection list, in order to avoid memory access issues that might occur when multiple threads share the same environment handle. (Bug #17240611, Bug #69864) Bugs Fixed * Memory leaks occurred in SQLPrepare() and SQLExecDirect() when SQLBindParamater was used on the SQL statements. This fix frees previous results of mysql_stmt_result_metadata() in order to prevent the memory leaks. (Bug #17400483, Bug #70113) * The exit condition for a for loop in stringutil.c is changed to avoid a possible out-of-bounds error and the associated reports by Valgrind. (Bug #17397596, Bug #64105) * Microsoft Visual Studio 2010 crashed when reading rows from any table in Server Explorer with connections to DSNs made by Connector/ODBC. (Bug #17304031, Bug #69950) * When SQL TIME data was converted to the C data type of TIMESTAMP, if the value of the hour field is greater than 24, the date fields did not get set to the current date and the fraction field for seconds did not get set to zero as required by the ODBC specifications. (Bug #17016839, Bug #69545) * When trying to create a linked server in Micrsoft SQL Server 2008 to a MySQL server set up with Connector/ODBC as a DSN, the Microsoft SQL Server (if it is a 64-bit version) crashed or the linked server suffered a catastrophic failure (if a 32-bit version of the Microsoft SQL Server is used). (Bug #16604346, Bug #63386) * When reading TIME column data using the SQLGetData method into the SQL_C_TYPE_TIME datatype, errors occured when the time string contained more than 6-digits (e.g., 120:53:44). (Bug #16176981, Bug #67793) * When called after SQLPrepare, the funciton SQLMoreResults returned SQL_ERROR, instead of SQL_NO_DATA as required by the ODBC specification. (Bug #16101282, Bug #67920) * Connector/ODBC used the ; character instead of a null byte (\0) to terminate keyword-value pairs in attribute strings. (Bug #15940689, Bug #66548) * When using the Unicode-enabled version of the Connector/ODBC driver to connect to any MySQL server of version 5.5.2 or older, all statements failed with the error message .Server does not support 4-byte encoded UTF8 characters.. (Bug #14838690, Bug #67428) * The configured values of a DSN's parameters overrode the values provided through the connection string, instead of the other way round.

OT: LAMP appliance for non-profit use
Hello All, I know this is little bit off-topic but I think users of this group can give good advice on this topic. We have a in-house built application using MySQL + PHP + Apache. It is essentially a elaborate collection of online forms that will be used for managing school scholarship in the 3rd world countries. The student/teachers will either come to the office or fill out the forms online. We have identified few pilot location and would like to deploy this application. However due to lack of IT support at the location we have decided to use a pre-configured appliance which support the LAMP stack. All we want to do is directly ship the appliance to the location, and remotely install our app. We want the appliance to require minimal maintenance and administration, and have a auto-update feature to get security patches etc. I had previously worked on a similar project and used Sun Cobalt 550 servers. But now I think Sun has stopped making them and you can only buy them refurbished and the auto-update features are severely limited. Any other suggestion??? We want the appliance to cost us $1,000 / unit.

Best practices for deleting and restoring records - moving vs flagging
Hello All, What are best practices for deleting records in a DB. We need the ability to restore the records. Two obvious choices are: 1) Flag them deleted or undeleted 2) Move the deleted records to seperate table for deleted records. We have a complex schema. However the the records that need to be deleted and restored reside in 2 different tables (Table1 and Table2). Table2 uses the primary key of the Table1 as the Foriegn key. The Primary key for Table1 is auto-generated. This make the restoring with the same primary key impossible, if we move deleted data to a different table. However if we just flag the record as deleted the restoring is quite easy.

I could implement a perl script to just check the replication status, and take necessary action to restart the slave if the SQL thread is down, but I was wondering if a more elegant solution existed.

Re: Good Database Philosophy Book?
David, If you want to learn about Databases and normalization and Relational Algebra, a really good book is: Fundamentals of Database Systems, by Elmasri and Navathe and Understanding Relational Database Query Languages by SW Dietrich I have studied the first book, cover to cover, and I still use it for reference. It is the best books for understanding Relational Algebra and Normalization. The second book was written by my Professor Dr. Dietrich and is also a very good book.

NAS vs SAN for data directory
Hello All, I am trying to decide which storage I should use for the Data Directory. My application has lots of 'SELECT's (80%) and fewer UPDATEs/INSERTs(20 %). I have the following choices of Data storage 1) Xiotech SAN (66 Mhz FCAL) 2) NAS 3) Internal SCSI 3 RAID 5 Will I achieve any better performance using one storage vs the other storage? In the past (for about 2 years), I have I used SAN with 33Mhz FCAL, and the performance has been quite exceptional. And I have encountered no problems. Any suggestions?

Best Pratices for mySQL Backups in Enterprise
We are in the process of implementing enterprise wide (20,000+ users) application that will use mySQL as the Database engine. I was wondering if the slashdot readers can provide me some details about best practices / experiences for Backing Up and Restoring mySQL Databases. I am planning to setup a cron job, to lock the tables, use msqlhotcopy and then unlock the tables. Is that a good backup strategy? Is there a ready-made perl script that I can use? Is there a commercial solution for Backups? What other things do I need to keep in mind? What do other people do in production use, where the DB is frequently? I have already read mySQL: The definitive guide to to using, programming and administring mySQL 4, but did not find ay good information about backing up and restoring, in the 24x7 operation for Data Center use. Any ideas will highly appreciated. Thanks Saqib Ali -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Best Pratices for mySQL Backups in Enterprise
mysqlhotcopy does your locking for you. So running ./mysqlhostcopy dbase /path/to/backup/dir is perfectly safe while database operations (selct, insert, update etc) are being performed? --- Saqib Ali http://www.xml-dev.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
optimizing left join query
Hello All, I have the following 2 tables and LEFT join query as follows: mysql describe user_lic; +++--+-+-+---+ | Field | Type | Null | Key | Default | Extra | +++--+-+-+---+ | license_id | bigint(20) | | PRI | 0 | | | user_id| bigint(20) | | PRI | 0 | | | location | char(30) | YES | | NULL| | +++--+-+-+---+ mysql describe user_info; +--+--+--+-+-+---+ | Field| Type | Null | Key | Default | Extra | +--+--+--+-+-+---+ | uid | int(10) unsigned | YES | | NULL| | | location | char(30) | YES | | NULL| | | mail | char(100)| YES | | NULL| | +--+--+--+-+-+---+ query = SELECT * FROM user_lic LEFT JOIN user_info ON user_lic.user_id=user_info.uid WHERE user_info.uid is NULL AND (user_lic.location = 'Rochester, US') When I run this query on a 'user_lic' table with 1000+ rows, it takes about 20+ mins to complete the query. However a similar query on a Oracle DB takes couple of minutes. I am using a high-end Sun Server, connected to a Xiotech SAN, using Fiber Optics. I dont think the Hardware is the bottle neck. I am wondering how I can optimize the Query/MySQL DB to make this query go faster.

load data local infile problems
Hi, I am creating a database for a university project. I say this because obviously certain things are not done the professional way due to time constraints. I've created a database, and entered the data into files. This is done because the teacher needs to see the files used for data entry. I then issue a command like: load data local infile Products.data into table Products; Occasionally I will get the response: Query ok, 29 rows affected (0.00 sec) Records: 29 deleted: 0 Skipped: 0 warnings: 0 But the vast majority of the time I get the response: Query ok, 0 rows affected (0.00 sec) Records: 29 deleted: 0 Skipped: 29 warnings: 0 I cannot seem to find any consistancy in MySQL's behaviour. This is an extremely annoying problem! If anyone out there can help then please do contact me. Thanks in advance.

loading data into a table and 1-many relations
Hi, I'm having a problem as follows: In my database (which just needs to work rather than be of commercial quality) I have an orders table. Each order contains an order number and a reference to ordered_items. Ordered_items table contains things like the name of the product and the price. Now obviously the orders-ordered_items link is a 1-to-many relationship since in any one order I should be able to order 5 different items. At the moment I am using: load data local infile orders.txt into table orders; to load the data. However, using this method I don't know how to enter say 10 ordered_item IDs into the tab-separated table contained in orders.txt. I'm sure that people on this list must make similar databases every day, and some basic help would be much appreciated.

currency: which data type?
Hi, I'm interested to know what data type people consider suitable for storing currency. In a table in my database for a university assignment, i have: create table Products( ... price double(4,2) not null, ...); However it has been suggested to me that double(4,2) is inappropriate and that decimal or numeric would be more appropriate. I only used double(4,2) because this is what is used in the MySQL tutorial (I think it's chapter 3 of the manual). Any thoughts on this matter appreciated.

Re: how to get a script to run/work
Hi, If you type mysql at the prompt you must interactively type commands at the mysql prompt and type quit to exit. However I think it's generally better in cases like yours to run in batch mode. Type: mysql pet.mysql. This will read the script from the file and execute it. If you want the output to be redirected to a file also add pets.out. In batch mode by default a concise format is used, but if you want tables to be drawn around the output like in interactive mode use the -t switch. Finally if you want the output to contain your typed commands use the -vvv switch. So you end up with: c:\mysql\scripts mysql -t -vvv pets.mysql pets.out I have only started using MySQL and only run it on a stand-alone system. If you are designing a database for a web site etc then you may need to provide extra parameters like the hostname. Hope this helps.

Create Table
Hi, For a university project I've recently started to learn to use MySQL. Obviously one of the first things I did, having read numerous tutorials was to create a database and attempt to add some tables. Unfortunately I have spent the past two weeks trying to do this presumably straight forward task and am sure that I am missing something. The problem occurs due to my wishing to place too many keywords after any attribute. If I create a simple table like: create table Products( ID int(7) unsigned not null unique zerofill default '000' auto_increment, primary key(ID)); I get an error message similar to: Error 1064 at line 3: You have an error in your SQL syntax near omitted text at line 2. After two weeks of changing combinations of keywords and deleting some and inserting others I finally found that the following command works: create table Products( ID int(7) unsigned zerofill default '000' not null unique auto_increment, primary key(ID)); So does anyone have any idea why the order of these keywords matters? In all the references on MySQL or SQL there is no mention of any specific order. While I've now got my first table working I'm still having difficulties getting other tables to work. Hopefully the answer to this question may shed some light on my difficulties. Thanks very much in advance.
