在sql Server中创建表时,如何设置字段的默认字符集？在
MySQL中,这样做：
CREATE TABLE tableName (
name VARCHAR(128) CHARACTER SET utf8
) DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
请注意,我在这里设置了两个字符集.这是多余的,我添加了两种方式只是为了演示.
我也设置了整理,以证明整理是不同的.我不是要求整理整理. Most questions询问sql Server中的字符集和编码是否使用归类回答,这是不一样的.
解决方法
As stated in BOL
Each sql Server collation specifies three properties:
- The sort order to use for Unicode data types (nchar,nvarchar,and ntext). A sort order defines the sequence in which characters are
sorted,and the way characters are evaluated in comparison operations.- The sort order to use for non-Unicode character data types (char,varchar,and text).
- The code page used to store non-Unicode character data.
上面的报价来自2000年的docs.下面也说明了这一点.
DECLARE @T TABLE
(
code TINYINT PRIMARY KEY,Arabic_CS_AS CHAR(1) COLLATE Arabic_CS_AS NULL,Cyrillic_General_CS_AS CHAR(1) COLLATE Cyrillic_General_CS_AS NULL,Latin1_General_CS_AS CHAR(1) COLLATE Latin1_General_CS_AS NULL
);
INSERT INTO @T(code) VALUES (200),(201),(202),(203),(204),(205)
UPDATE @T
SET Arabic_CS_AS=CAST(code AS BINARY(1)),Cyrillic_General_CS_AS=CAST(code AS BINARY(1)),Latin1_General_CS_AS=CAST(code AS BINARY(1))
SELECT *
FROM @T
结果
code Arabic_CS_AS Cyrillic_General_CS_AS Latin1_General_CS_AS ---- ------------ ---------------------- -------------------- 200 ب И È 201 ة Й É 202 ت К Ê 203 ث Л Ë 204 ج М Ì 205 ح Н Í
