To show our gratitude towards those who help us, and to help MySQL users help us even better, we will soon be announcing a “Quality Contributor Programme“. As we have identified the best contributors of 2006 based on submitted bug reports, I asked a number of people last Friday and Saturday whether they would accept to be listed on our Quality Contributor list on our website at dev.mysql.com.

I am overwhelmed by the quantity and quality of the response during the past 48 hours. Let me already now give some pre-announcement recognition to some of those who have helped us make MySQL better.

Don’t worry: we do understand that the main reason users report bugs is to get them fixed. However, we still think we have plenty of opportunities of improving our ways when it comes to making it easier for you to help us, even if our bug fixing capacity should remain unchanged. Expect to soon hear more about this from …

The short version is that among 380 wireless application developers surveyed,
30% use Microsoft SQL Server as a backend,
20% use MySQL,
16% use Oracle.

Microsoft can offer bundles, so they can just offer SQL Server cheaply so long as companies have the MSDN service (I don’t know if they do, but they can). MySQL and Oracle are standalone offerings — no bundles. And as an embedded database, a MySQL license must be bought.

So this research shows that when customers have to pay for a database, they choose MySQL over Oracle. Granted, they choose Microsoft SQL Server over both.

Now, many folks say I’m a MySQL nut. I am, but that’s not the point — I do not advocate that MySQL is the only …

Solid Information Technology, a provider of fast, always-on and affordable databases used in more than 3,000,000 mission-critical deployments worldwide, today announced that solidDB? for MySQL outperformed other MySQL transactional database engines in a public benchmark test. The benchmark results confirmed that solidDB for MySQL is the open source database that meets the performance and scalability requirements of high throughput, mission-critical applications. The publication of the results also coincided with the general availability of solidDB for MySQL, an open source relational database management system (RDBMS) that has been developed in partnership with MySQL AB and consists of the MySQL® server and solidDB Storage Engine.

Ever wondered how threads exchange data between themselves?

This sharing and exchange of data is made possible by inter-process communication, or IPC for short. There are several different types of inter-process communication for instance (IPC,System V IPC and POSIX IPC). In addition Solaris provides an additional advanced Solaris IPC.

According to Wikipedia:

Inter-Process Communication (IPC) is a set of techniques for the exchange of data between two or more threads in one or more processes. Processes may be running on one or more computers connected by a network. IPC techniques are divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). The method of IPC used may vary based on the bandwidth and latency of communication between the threads, and the type of data being …

There have been a few posts on PlanetMySQL regarding primary keys and the importance of choosing the right one. This is even more important when the table uses InnoDB. You've read different posts of why it is so important. Now, I'm all about benchmarks and showing the details. So I'll take a table from my previous posts about MySQL 5.1 partitioning and show what I found.

This table was created under MySQL 5.1.12-beta:

CREATE TABLE `big_table_test1` (
`entity_id` int(11) NOT NULL DEFAULT '0',
`col1` int(11) NOT NULL DEFAULT '0',
`col2` int(11) NOT NULL DEFAULT '0',
`col3` int(11) NOT NULL DEFAULT '0',
`col4` int(11) NOT NULL DEFAULT '0',
`col5` int(11) NOT NULL DEFAULT '0',
`col6` int(11) NOT NULL DEFAULT '0',
`ymdh` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`imps` bigint(20) NOT NULL DEFAULT '0',
`clicks` int(11) …

In Oracle and MySql, to get the column name and data type of a table, you can use:

desc MyTable

or

describe MyTable

The equivalent of desc in Sql Server is sp_columns. Therefore, run the command below will get similar results:

sp_columns MyTable

Today we have released MySQL Tools for Microsoft Visual Studio 1.0.2 GA --a downloadable plug-in for Visual Studio 2005 that allows Windows developers to quickly build MySQL data-driven applications with Visual Studio. With this plug-in, developers will be able to create, modify and manage MySQL database objects with an easy-to-use interface from within the Visual Studio IDE. This product is delivered as a package compatible with Visual Studio 2005 and delivers the following features:

• DDEX (Data Designer Extensibility) compatibility
• Ability to work with MySQL objects (tables, views, stored procedures, etc) from within Server Explorer
• Support for MySQL versions 4.1 and higher

IMPORTANT
This product will only work correctly with Connector/Net 5.0.2 and higher.

This release does not include the ability to work with the DataSet designer but we will be making a beta …

The central component of most operating systems is the kernel. The kernel manages the resources of a system. In addition, the kernel facilitates and manages the communication between a system's hardware and software components.

Two levels of execution are provided by hardware: kernel mode execution and user mode execution. When in kernel mode, the software program can access all the instructions and every accessible piece of hardware. A program is in kernel space if running in kernel mode and in user space if running in user mode.

The Solaris kernel is a monolithic kernel, much like most Unix systems, as compared to a microkernel.

The software said to be running in …
