What is a sorting rule?

What is a sorting rule? "In Microsoft SQL Server 2000,

The physical storage of strings is controlled by sorting rules. Sorting rules specify the bit mode and storage of each character

Rules Used for saving and comparing characters. "

Run the following statement in the query analyzer to obtain all the sorting rules supported by SQL Server.

Select * From: fn_helpcollations ()

The name of a sorting rule consists of two parts. The first half is the character set supported by this sorting rule.

For example:

Chinese_prc_cs_ai_ws

First half: the Unicode character set. The chinese_prc _ pointer sorts Unicode in simplified Chinese characters.

The second half of the sorting rule is the suffix meaning:

_ Bin binary sorting

_ Ci (CS) is case sensitive, CI is case insensitive, and CS is case sensitive

_ Whether AI (AS) distinguishes stress, AI does not distinguish,

_ KI (KS) indicates whether Kana is distinguished. Ki is not distinguished, and KS is distinguished.

_ Whether wi (WS) is differentiated by width WI and WS

Case Sensitive: select this option if you want to make the comparison between uppercase and lowercase letters different.

Accent differentiation: select this option if you want to treat the comparison as different from the accent and non-accent letters. If this option is selected,

Comparison also treats letters with different accents as unequal.

Kana differentiation: select this option if you want to treat Katakana and katakana as different Japanese syllables.

Width differentiation: select this option if you want to make the comparison between halfwidth and fullwidth characters.
