RE: Hebrew
Greg I use MySQL Control centre to access my dbase and I have set My character_set_xxx variables to Hebrew I then looked at the values, show variables like '%char%'; and all was fine. However if I then exit MySQL Control centre and then go back to it my character_set_xxx variables are all back at their defaults ? I'm assuming this is a permissions type problem?

Re: insert - select from two different applications race condition?
- Original Message - From: Aragorn [EMAIL PROTECTED] To: mysql@lists.mysql.com Sent: Saturday, March 12, 2005 1:47 AM Subject: insert - select from two different applications race condition? I have a simple problem... I'm using mysql 4.1.9/innodb table and two small python applications A and B first application A is executed, and do a simple INSERT into a table then application B is executed: - B does a SELECT in the same table, that should return the entry created by application A (and based on the result, an UPDATE (to the entry application A has created) or an INSERT if it can't find it... but in this scenario it should find it since B is always executed just after A is) I can be sure that application A is executed before application B is started, even though B can be started just after A is done. The problem is that every once in a while, the SELECT doesn't return anything... even though I can check that application A created the entry... Everything looks as if the INSERT from application A hasn't completed when the SELECT in the application B is performed... Even though application A terminated before application B started! Any clue about what's going on? How can I prevent that? Are you sure that Application A committed its INSERT before B attempted to read the row? Remember, the new row isn't accessible to Application B until A has done the INSERT *AND* committed the INSERT (and released any locks it holds on the table into which the row was inserted). You should be checking the return code from the INSERT and the commit to ensure that both worked; if you aren't doing that, either step could fail silently and leave you thinking that the INSERT was successful or that it was successfully committed when it wasn't. That would explain why Application B doesn't see the row. The likelihood of this scenario can be minimized if you have turned 'autocommit' on; then, each statement is committed immediately upon successful completion but, even then, the INSERT has to be successful before the automatic commit has the desired effect. Again, you need to verify that the INSERT was successful each time you do one. Please note that I am NOT saying that you should always use autocommit! There are many good reasons not to use autocommit, particularly when you have some sort of multi-part transaction where all parts have to either succeed or fail together. The classic example of this is a bank transfer where you move money from one account to another; you definitely don't want to commit until both the debit and the credit are complete. -- The other thing you might want to consider is Application B. Is it possibly encountering a lock that prevents it reading the row created by Application A? If it tries to read the row before A has released the lock, which could potentially happen if Application A hasn't committed (or, in some cases ENDED), it might be encountering a lock preventing reading. Now, if you are testing for that lock within your code and reacting appropriately, you should be fine but if you simply return an empty result set without checking for a lock, you might fool yourself into thinking the row is not there when it is present but inaccessible. Let me stress that this second scenario, the one where Application B encounters a lock, may not be possible in MySQL. I don't know anything about how locking works in MySQL. However, the situation I describe *is* possible in DB2, which I've used for many years. Since MySQL behaves like DB2 in many respects, it seems possible that this scenario could happen in MySQL as well. But I could be dead wrong so please don't scream at me if I am.

Limit of a sql script
Hi , I'm using mysql 4.1.4 gamma with InnoDB suse 8.2 reiser fs. I'am doing backups using mysqldump which creates a sql script with the structure for all tables plus the correspondig commands to create them and also the data to be inserted in each one of them. Latter when I have to restore one of these backups I create the corresponding database an run the following from the shell mysql db_name db_name.sql This seems to work just fine so far, but I'am concerned about the size of this script ( db_name.sql has 450mb ). My question is: there could be a size problem when mysql handles the content of this script due to its size. In other words is there a limit on the size of a script that mysql can hable from the command line ?

MySQL/InnoDB-4.0.24 is released
Hi! InnoDB is the MySQL table type that supports FOREIGN KEY constraints, transactions, row-level locking that is never escalated, multiversioned concurrency control, asynchronous unbuffered disk I/O on Windows, and a non-free online hot backup tool. InnoDB is an 'ACID'-compliant table type. InnoDB is included in all MySQL downloads from http://www.mysql.com, and in the commercial MySQL Pro license. Release 4.0.24 is a bugfix release of the old stable MySQL-4.0 branch. Please observe this bug fix in upcoming 4.0.25: * Fixed a bug: MySQL-4.0.23 and 4.0.24 could complain that an InnoDB table created with MySQL-3.23.49 or earlier was in the new compact InnoDB table format of 5.0.3 or later, and InnoDB would refuse to use that table. (The same bug exists in 4.1.8 - 4.1.10.) There is nothing wrong with the table, it is mysqld that is in error. Workaround: wait that 4.0.25 or 4.1.11 is released before doing an upgrade, or dump the table and recreate it with any MySQL version = 3.23.50 before upgrading to 4.0.23 or 4.0.24. Full changelog for 4.0.24: Functionality changed or added: * Added configuration option and settable global variable innodb_autoextend_increment for setting the size in megabytes by which InnoDB tablespaces are extended when they become full. The default value is 8, corresponding to the fixed increment of 8 MB in previous versions of MySQL. * Do not acquire an internal InnoDB table lock in LOCK TABLES if AUTOCOMMIT=1. This helps in porting old MyISAM applications to InnoDB. InnoDB table locks in that case caused deadlocks very easily. Bugs fixed: * Work around a problem in AIX 5.1 patched with ML7 security patch: InnoDB would refuse to open its ibdata files, complaining about an operating system error 0. * Fixed a memory corruption bug if one created a table with a primary key that contained at least two column prefixes. An example: CREATE TABLE t(a char(100), b tinyblob, PRIMARY KEY(a(5), b(10))). * Use native tmpfile() function on Netware. All InnoDB temporary files are created under sys:\tmp. Previously, InnoDB temporary files were never deleted on Netware. * Honor the --tmpdir startup option when creating temporary files. Previously, InnoDB temporary files were always created in the temporary directory of the operating system. On Netware, InnoDB will continue to ignore --tmpdir. (Bug #5822) * Fix a theoretical hang over the adaptive hash latch in InnoDB if one runs INSERT ... SELECT ... (binlog not enabled), or a multi-table UPDATE or DELETE, and only the read tables are InnoDB type, the rest are MyISAM; this also fixes bug #7879 for InnoDB type tables. (Bug #7879) * Fixed a bug: 32-bit mysqld binaries built on HP-UX-11 did not work with InnoDB files greater than 2 GB in size. (Bug #6189) * Fixed a bug: InnoDB failed to drop a table in the background drop queue if the table was referenced by a foreign key constraint. * Fixed a bug: if we dropped a table where an INSERT was waiting for a lock to check a FOREIGN KEY constraint, then an assertion would fail in lock_reset_all_on_table(), since that operation assumes no waiting locks on the table or its records.

Mysqldump alternative due to bug

Problems with a full backup
Hi! I'm learning mysql and I have a problem when i make a full backup with mysqldump. I have a lot of table rows written in spanish. In the backup file (.sql) I have problems with certain spanish characters like: á -- Ãi é -- é í -- Ã- ú -- ú and so many others like that. However, when I make an incremental backup with the *.bin-* files I don't have this problem. I use MySQL 4.1.X with the default character set(latin1) and the default collation (latin1_swedish_ci). I´ve tried with the latin1_spanish_ci and with another character set (utf8 with the utf8_spanish_ci collation). But the problem doesn´t disappear. Can anybody help me?
