MySQL introduced the basics of dealing with different character sets and languages.

Several concepts.

• Character Set: A collection of letters and symbols
• Code: internal representation of a character set members
• Proofreading: how to provide instruction character comparisons

-- 显示所有可用的字符集，描述和默认校对
SHOW CHARACTER SET;

-- 显示支持的校对完整列表
SHOW COLLATION;

-- 确认使用字符集和校对
SHOW VARIABLES LIKE 'character%';
SHOW VARIABLES LIKE 'collation%';

-- 给表指定字符集和校对
CREATE TABLE
(
    column1, INT
    column2, VARCHAR(10)
)DEFAULT CHARACTER SET heberw
COLLATE hebrew_general_ci;

-- 给列指定字符集和校对
CREATE TABLE
(
    column1, INT
    column2, VARCHAR(10)
    column3, VARCHAR(10) CHARACTER SET latin1 COLLATE latin1_general_ci
)DEFAULT CHARACTER SET heberw
COLLATE hebrew_general_ci;

-- 校对对数据排序起着重要作用，下面区分大小写
SELECT * FROM customers
ORDER BY lastname, firstname COLLATE latin1_general_ci;
