Display and update table in database

จาก Wiki2

Database หากมีภาษาไทยต้องเพิ่ม Column width ใช้ 7 char ต่อภาษาไทยหนึ่งตัว และต้องปรับ Collate ด้วย

ALTER TABLE test DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci

CREATE TABLE `customer` (
  `CustomerID` varchar(4) NOT NULL,
  `Name` varchar(50) NOT NULL,
  `Email` varchar(50) NOT NULL,
  `CountryCode` varchar(2) NOT NULL,
  `Budget` double NOT NULL,
  `Used` double NOT NULL,
  PRIMARY KEY  (`CustomerID`)
) ENGINE=MyISAM;
