DH says a saturated link may be causing some slowdowns on the way into MySQL boxes. I had no trouble pinging mine, but getting non-cached pages may be tricky until they figure out what’s happening to their hardware.

We have mock up data in both table as below:

—————————————————————

And we want to select data in table1 that is not avaiable in table2, so when you want to do as I said.

You should use:

SELECT table1.*

FORM table1 LEFT JOIN table2 ON table1.ID = table2.Table1ID

WHERE table2.Table1ID is null

If you want to use MySQL Database with Asp.net, then here is a link which explains:

http://www.15seconds.com/issue/050407.htm

• Download of MySQL Server
• MySQL Administrator
• MySQL Query Browser
• .Net Connector (For Asp.net Integration)

The above link has explained in detail, with proper screenshots, from where to download installers, how to install with step by step screens and explanations, and also how to create sample asp.net application with MySQL database, create MySQL database (schema), create MySQL Table, Insert Data, and populate that data in asp.net gridview.

Kemaren ada mahasiswa yang nanya, gimana caranya akses remote server MySQL. Misalnya Remote server MySQL nya di IP 192.168.100.1 lalu mau akses dari host yang berbeda dengan IP: 192.168.100.2.

Mengingat sudah lama tidak ngoprek – ngoprek lagi linux, maklum sekarang prioritasnya agak bergeser, maka saya harus googling lagi. Bagaimanapun ngoprek selalu menarik, walau untuk hal – hal yang dulunya sudah sering saya kerjakan.:). Bukan terpaksa Cuma sayang kalau pengetahuanya hilang hanya karena waktu dan kemalasan. Jadi pertanyaan itu baik buat kita me-refresh pengetahuan.

Nah, caranya begini: Kalau menggunakan WAMP atau XAMPP di Windows, cukup dengan perintah:

mysql>grant all privileges on *.* to ‘coba’@’192.168.100.2’ identified by ‘coba’;
mysql>flush privileges;

Lalu dari client, silahkan mengakses MySQL server tersebut:
$ mysql –ucoba –h192.158.100.1 –p coba

Cuman, skrip itu tidak jalan di linux yang secara default menerapkan tingkat keamanan yang baik. Pada sisi Server MySQL perlu diedit konfigurasi MySQL nya:

$sudo nano /etc/mysql/my.cnf

Cari baris:
[mysqld]
…..
…..
bind-address = 192.168.100.1
…
…

Lalu, restart mysql server:
$ sudo /etc/init.d/mysql restart

Nah, sekarang coba konek lagi mysql server dari client. Oh ya, supaya server mysql tersebut dapat diakses dari client mana saja maka ip: ’192.168.100.2’ diganti menjadi tanda ‘%’. Selamat mencoba

Sarò conciso:

1. Andate qua e scaricate il pacchetto adatto a voi. Se avete un core 2 duo, selezionate x86_64. (mac osx 10.5 sta per leopard, 10.4 sta per tiger…)
2. Installate tutto tranne MysqlStartupitem.pkg (scegliete installa per tutti gli utenti quando richiesto)
3. Aprite il terminate (in Applicazioni/Utility)
4. Scrivete vim .bash_profile [invio] poi schiacciate il tasto i
5. aggiungete questa riga: export PATH=”$PATH:/usr/local/mysql/bin”  (non fate copia e incolla)
6. schiacciate esc poi la sequenza di tasti :wq (inclusi i due punti), poi [invio]
7. ora siete di nuovo al terminale. Inserite il comando sudo su (e quando richiesto la vostra password)
8. Ora inserite il comando mkdir /var/mysql
9. Adesso il comando ln -s /tmp/mysql.sock /var/mysql

Fatto. Ora potete andare in Preferenze di sistema per far partire il server.

Se al punto 7 ci sono problemi con la password, sicuramente il vostro utente è sprovvisto di quest’ultima. Andate in preferenze di sistema>Utenti e rimediate.

SQLyog adalah sebuah aplikasi yang digunakan sebagai gui database manager untuk database MySQL. Dengan menggunakan aplikasi ini, akan memudahkan kita dalam membuat database baru, membuat tabel, membuat user baru MySQL, menambahkan entri ke tabel, menghapus entry maupun mengubah entry.

Dari sisi kemudahan, jelas aplikasi ini lebih mudah digunakan dari pada kita harus capek-capek mengetikkan perintah sql pada mysql console hanya untuk membuat database baru, maupun membuat tabel dengan jumlah field yang sangat banyak.

Apalagi terjadi kesalahan sintaks yang membuat kita harus mengetikkan ulang perintah sql tersebut dikarenakan tidak ada fitur history pada MySQL.

Dengan menggunakan SQLYog, kita dapat mengotomatisasikan pekerjaan itu karena aplikasi ini berbasis GUI(Graphical User Interface), walaupun SQLYog tetap menyediakan sebuah text-area untuk mengetikkan perintah sql.

SQLYog Enterprise versi trial hanya dibatasi penggunaanya selama 30 hari. Namun kita tetap bisa menggunakannya selama yang kita mau.

Coba lihat skrin shut di bawah yang menunjukkan bahwa periode penggunaan aplikasi ini sudah expired yang artinya aplikasi trial ini tidak bisa kita pergunakan lagi.

Uninstall aplikasi ini dan menginstall yang baru tidak akan mengubah keadaan. Jadi lebih baik kita gunakan cara dibawah.

Caranya adalah:

Memundurkan tanggal pada komputer kamu. Tanggal expired aplikasi ini pada komputer saya adalah pada hari ini tanggal 07 Agustus 2008. Agar saya tetap dapat mengubah aplikasi ini, saya memundurkan tanggal komputer saya menjadi tanggal 06 Agustus 2008.

Dan akhirnya proteksi SQLyog Enterprise Edition versi trial pun terkuak sedikit. Lihat skrin shut dibawah untuk melihat hasilnya.

Hehehe…. tersisa satu hari sebelum aplikasinya expired kan? Jika besoknya expired lagi, kamu tinggal mundurin lagi deh tanggalnya

Repot ya? hehehe… namun saat ini saya hanya bisa ngasih trik itu. Saya belum oprek-oprek ke registry ataupun file konfigurasi yang terenkripsi milik SQLYog, soalnya lagi sibuk, hehehehehe….

Kalau kamu mau menggunakan aplikasi ini, donlot langsung versi trialnya dari sini.

Atau klo kamu punya duit, beli aplikasinya dan donlot di sini.

Selamat ber SQLYog ria

We’ve got a new member of our programming team, Uthay, I can’t even say or spell his full name, but anyway, he came along and showed me this tool called SQLyog.

Although we only had the community edition after some coaxing we managed to get the boss to shell out for the full version, enterprise edition.

This is absolutely superb, it is WELL WORTH upgrading the full enterprise version has some amazing tools that make database development MUCH easier. Especially when like us we have to modify and change databases then roll out the changes to another server. For example when we have 5 or 6 versions of our application out there and want to roll out the new application, that’s easy enough, but remembering the differences between the two versions is a bit of a pain, with this tool we can just syncronize them and it will modify the destination tables (and data if we want) to match the source.

I particularly like the Query development tool, one of the good things about good old Microsoft Access was how easy it was to build complex queries, in this software it is just as easy, particularly useful when building large scale data structures.

It’s such a shame it doesn’t support anything else apart from MYSQL. However I will be transmographying a database from a SQL server over to MYSQL JUST TO USE IT!

There is a community version but the full version is only like £50 so it’s well worth purchasing.

Por defecto, amarok nos permite construir su colección mediante SQLite, lo cual no viene mal si no quieres liarte configurando otras cosas como el MySQL. Desgraciadamente, cuando tu biblioteca es demasiado grande, SQLite no funciona todo lo bien que debería, volviendo a Amarok un tanto lento e inestable. Para solucionarlo, podemos utilizar una base de datos mas seria como MySQL o PosgreSQL. En este caso lo haremos con MySQL.

Lo primero que tenemos que hacer es instalarlo desde los repositorios. Abrimos un terminal y escribimos:

sudo apt-get install mysql-server

Una vez que se haya instalado nos pedirá la contraseña para el root de MySQL. Se la ponemos y entramos como root:

sudo mysql -u root mysql -p

Una vez dentro de MySQL nos saldrá un prompt diferente. Pongo aquí los comandos genéricos y remarco las variaciones de cada usuario con cursiva:

SET PASSWORD=PASSWORD('contraseña');

CREATE DATABASE amarok;

GRANT ALL ON amarok.* to usuario@localhost IDENTIFIED BY 'contraseña';

quit;

Una vez hecho esto vamos a Amarok, menú Preferencias y Configurar Amarok.

Vamos al apartado colección y en el desplegable de Base de datos elegimos MySQL, servidor localhost, base de datos amarok, usuario tuusuario y contraseña tucontraseña. Si os da problemas podeis probar a poner root en el usuario. Os recomiendo encarecidamente que lo hagais, el aumento de rendimiento es muy significativo.

Update:

It was not the static IP address, but the fact that due to a typo in /etc/network/interfaces the loopback device was not active.

Installing MySQL server on Ubuntu fails if the machine has a static IP address.

sudo apt-get install mysql-server

Results in:

If you are looking for a real database (something with a bit more umph than MS Access) check out these two

PostgreSQL

EnterpriseDB

I have used PostgreSQL in some of my projects and have found it to be very capable. I like the views, stored procedures, triggers and rules in particular.

EnterpriseDB is new to me but this article

Vonage’s Open Source Database Odyssey

Caught my attention. Turns out EnterpriseDB is based on PostgreSQL. You may have heard of MySQL and not heard of PostgreSQL. If so that is a shame. When I initially went looking for a database for Linux some years ago, there seemed to be two main contenders. MySQL and PostgreSQL. MySQL had (and still does have) more attention than PostgreSQL but two things in particular turned me away from it. At the time I started looking the license did not allow for free commercial use. Even more glaring (in my opinion) was the fact that it did not support views (SQL command / concept). I went with PostgreSQL as a result. As I understand it they have fixed some of that but I still find PostgreSQL a bit easier to work with. At any rate, check them out.

maybe this will save you an hour or so of your life to learn from my mistake.  When installing MySql 5.0 on windows and you screw up the configuration and want to start over from scratch a couple things will help you out.

1. Remove the MySql service before you uninstall.  This can be easily done with the configuration manager and i recommend this because it seemed ( atleast on my system) that uninstaling the program didn’t always remove the service.
2. Delete the MySql directory in program files after you uninstall.  The configuration files are kept here, so if you don’t delete this before you reinstall, you have to battle with the same botched config files again.

For about a couple of months I have been religiously studying PHP and MySQL to develop websites. Previously, when I was studying Perl I did not carefully screen for the “perfect” book to learn from. At that time, I figured any book would do but I found out later that some books covered much more content than others and were also presented much better.

So this time, I decided to screen PHP books for the one that would be best for me, and of course that meant most content and presentation.

After reviewing several books, I thought it might be beneficial for aspiring PHP developers like me if I gave a review of which books are good beginner book and which books are good for intermediate level. I will list the books in the order from beginner to intermediate (I don’t have an advanced category yet because I am still not at that level >.< ):

1. PHP and MySQL Web Development, 3rd Ed., Luke Welling and Laura Thomson [rating 4/5]: This is a great beginners book and the content is quite comprehensive. The book is broken down into five parts: PHP, MySQL, e-commerce/security, advanced PHP, and case studies (6 example sites). The PHP and MySQL gives all the standard information that you’d find in other PHP books, plus a bit more in terms of content. Where it might lack content, they give you references for further reading. What I did find lacking though is comprehensive information about PHP security. Most beginner books will not cover this topic in depth but after reading “Essential PHP Security”, I have found that PHP security is a crucial aspect in web development. Welling and Thomson do mention about encryption and using SSL as a means for sending encrypted messages, but they did not go over in depth on topics such as cross site scripting, SQL injection and other typical ways web sites can be compromised by malicious users. Overall, this book is a great place for beginners to start with. My only gripe is the lack of security topics and how to filter incoming and outgoing data.
2. Core Web Application Develoopment with PHP and MySQL, Marc Wandschneider [rating 4.5/5]: This book, like PHP and MySQL Web Development, is a great place to start for beginners. The book explains everything concisely, more so than PHP and MySQL Web Development. I also feel that it is slightly more comprehensive in the security subject, but this book also does not do justice as I feel it should. Wandschneider does mention though about protecting by filtering data, but he doesn’t go into depth as I had hoped he would. Some might consider this book is for intermediates (one of the reviewers in Amazon.com felt it was so) but I feel that it’s also good for beginners. Wandschneider might go into depth a little more on each topic as compared to other authors, but I think that is a good thing, especially for beginners because it’ll help beginners develop a good foundation for understanding PHP. In any case, this is a great book that probably will be frequently referred to.
3. Core PHP Programming, 3rd Ed., Leon Atkinson [rating 4/5]: This book is written more like a reference book rather than a teaching book. If you learn better by seeing all the functions in the PHP library, this might be the book for you to begin with. To me, I like to read a book that teaches you how to program first, then get a reference book to further learn about the functions that were not listed in the teaching book. This book seems to be very comprehensive, but I am not sure how comprehensive it is because I don’t have enough knowledge of the PHP library.
4. PHP 5 Unleashed, John Cogshall [rating 5/5]: This book is more of an intermediate level book. It’s best for reading after reading one of the books listed above. I like this book a lot because it shows you how to write PHP effectively. It tells you what to watch out for and what not to do, which is great to know after you learn about the language. It doesn’t cover the basics in depth, thus beginners might get lost.
5. Essential PHP Security, Chris Shiflett [rating 4.5/5]: This is definitely an intermediate book. It’s a great read right after you learn about PHP, since most beginners PHP books lack the topic on security. This is where I learned majority about PHP and web application vulnerabilities. With out it, I would never have known how vulnerable my codes are if I simply followed the examples from the beginners books. This book covers a lot of topics on security. The only issue I have is the lack of examples. This book would have been better if the examples were explained further. Sometimes I felt like the subject was cut short. The book is quite thin, so adding a bit more ‘meat’ won’t hurt. But so far this is the only book I’ve read that discusses PHP security in depth. There are a few other books out there that I’d like to get a hold of to see just to compare with this book.

There are a few other books I’ve looked at that I am not going to mention because I believe the books mentioned above are the better ones out there for beginners and intermediates.

Recommendations for book purchases: I recommend for beginners to start with “Core Web Development with PHP and MySQL” then move on to “Essential Web Security”. If you want to brush up on PHP 5 and hone your skills, follow up with “PHP 5 Unleashed”. If you want something that is more beginner, but less comprehensive, start with “PHP and MySQL Web Development” in place of the Core book.

Very Beginner: “PHP and MySQL Web Development” -> “Essential Web Security” -> “PHP 5 Unleashed”

Beginner: “Core Web Development with PHP and MySQL” -> “Essential Web Security” -> “PHP 5 Unleashed”

Intermediate: “PHP 5 Unleashed” -> ???
