MySql Trigger - Basic

Trigger คือการแทรกการกระทำ (Method/Function) ลงไว้ใน Database โดยสามารถใส่เงื่อนไขต่างๆได้เหมือนกับภาษาโปรแกรมทั่วไปครับ โดยเมื่อเกิด Query ใน Mysql แล้วตัว Database จะทำการไล่ Check ว่ามี Trigger ไหนตรงตามเงื่อนไขบ้าง และเรียกใช้งาน

การใช้ Trigger เป็นเหมือนดาบสองคม มีทั้งข้อดีแล้วข้อเสียครับ จะแจกแจงคร่าวๆเท่าที่พอนึกออกไว้ให้ครับ

+ ดูดีมีชาติตระกูล เร็ว (เร็วกว่าที่ส่งข้อมูลไปๆมาๆระหว่าง Mysql กับ Php/Server-side script อื่นๆ)

+ ทำบางอย่างที่ทำด้วยโค้ด Server-side script มาตราฐานไม่ได้ หรือไม่สะดวกนัก โดยการ Hook เข้าไปในระบบของ DB เลย

- Debug ยาก ยิ่งมีภาษาเพิ่มเข้ามาอีก ยิ่งเพิ่มความปวดหัว

- ยึดติดกับ Platform เนื่องจาก Trigger ไม่มีมาตราฐานชัดเจน ทำให้เมื่อย้ายไปใช้ตัวอื่นจะต้องศึกษาใหม่

Replacement

จริงๆ ในหลายๆกรณีก็ไม่จำเป็นต้องใช้ Trigger เช่นการ Update Table ที่เป็น Foreign key โดยสามารถใช้คำสั่ง Cascade ช่วยได้

http://dev.mysql.com/doc/refman/5.1/en/innodb-foreign-key-constraints.html

Mysql Trigger พื้นฐาน

หน้าตาตัวอย่าง TriggerCREATE TRIGGER trigger_name BEFORE UPDATE ON table_name FOR EACH ROW BEGIN IF NEW.dirty=0 OR NEW.dirty=1 THEN SET NEW.dirty=1; ELSE SET NEW.dirty=0; END IF; END;

  • CREATE TRIGGER trigger_name คำสั่งสร้าง Trigger
  • BEFORE UPDATE Event หลักๆที่เราสามารถ Hook trigger ของเราเข้าไปได้ ได้แก่ INSERT, UPDATE, DELETE โดยสามารถเลือกว่าจะทำการ Hook ก่อนหรือหลัง (BEFORE / AFTER) Query เหล่านั้นได้
  • ON table_name เลือก Table ที่ต้องการให้ Trigger ทำงาน
  • หมายถึงข้อมูลเก่าก่อนที่จะเกิดการรัน Query นั้นๆ
  • นอกจากนี้ยังสามารถแทรก Query มาตราฐาน (INSERT,UPDATE,DELETE และอื่นๆ) ลงใน Trigger ได้เลยอีกด้วย ซึ่งเราสามารถนำตัวแปร ROW,OLD,NEW มาใช้งานได้เช่นกัน

สร้าง Trigger บน phpMyAdmin

ถ้าได้ลองเอาโค้ดตัวอย่างไปลอง Run ใน phpMyAdmin จะพบว่าไม่สามารถทำงานได้ ด้วย Error ที่อ่านไม่ค่อยจะเข้าใจนัก

เหตุผลphpMyAdmin ไม่สามารถ Run คำสั่งนี้ได้ เนื่องจากเกิดการสับสนเรื่อง Delimiter ของ Mysql กับ คำสั่งใน Trigger

วิธีการแก้ไข แก้ได้ด้วยการ เปลี่ยน Delimiter เป็นตัวอักษรอื่นแทน semicolon “;” ตามรูป

เปลี่ยน Delimiter ใน phpMyAdmin

ในตัวอย่างเปลี่ยนเป็น ;; แทนครับ โดยถ้าหากเราต้องการสั่งให้ phpMyAdmin ทำงานหลายๆ Query พร้อมกันก็ให้ใส่ ;; แทน ;

InstallingBigBlueButton

How to install BigBlueButton like a real developer. :-)

These instructions will walk through how to install BigBlueButton from source onto Ubuntu. If you are using CentOS, seeInstallingBigBlueButtonCentOS. In most cases, you’ll want to install from packages, but if you want to really understand how BigBlueButton is setup, the following steps will show you how to install each component.

To start, you’ll need a computer running Ubuntu — either a physical machine or a virtual machine (VM). The easiest way to start with a VM images is to download a Ubuntu VM image from http://www.vmware.com/appliances/directory/va/147323/download and start it in VMWare Player

The only prerequisite is that your Ubuntu machine has a network connection.

  • To start, check if you have a network connection
  •  > ping www.google.com
    
    If you get an error saying yout eth0 is not connected, then fix it by:
    
      Check if it is using eth1 
    
    root@ubuntu904server:/usr/local# ifconfig -a
    eth1      Link encap:Ethernet  HWaddr 00:0c:29:dd:b4:51
              inet addr:192.168.0.154  Bcast:192.168.0.255  Mask:255.255.255.0
              inet6 addr: fe80::20c:29ff:fedd:b451/64 Scope:Link
              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
              RX packets:4080349 errors:0 dropped:0 overruns:0 frame:0
              TX packets:3932137 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:1000
              RX bytes:1216680270 (1.2 GB)  TX bytes:822963271 (822.9 MB)
              Interrupt:19 Base address:0×2000
    
    lo        Link encap:Local Loopback
              inet addr:127.0.0.1  Mask:255.0.0.0
              inet6 addr: ::1/128 Scope:Host
              UP LOOPBACK RUNNING  MTU:16436  Metric:1
              RX packets:12938 errors:0 dropped:0 overruns:0 frame:0
              TX packets:12938 errors:0 dropped:0 overruns:0 carrier:0
              collisions:0 txqueuelen:0
              RX bytes:40299608 (40.2 MB)  TX bytes:40299608 (40.2 MB)
    
    root@ubuntu904server:/usr/local# vi /etc/udev/rules.d/70-persistent-net.rules
    Swap the two entries by eidting “NAME=eth1″ to “NAME=eth0″ and vice versa.
    
    Reboot your machine. 
    Check if you manage to connect to the internet. 
    If you are running on a Virtual Machine, make sure the VM’s network adapter is using a Bridged connection instead of NAT. 
    On the VMWare player this is enabled in the Devices menu at the top.
