Sybase Adaptive Server
Enterprise在中文支持方面，提供的排序方式比較單一。如果使用CP850（支持GB2312標準），排序方式是比較多的。但GB2312的漢字
庫太小，多數(shù)情況下，我們至少要使用CP936甚至GB18030字符集。在使用CP936、GB18030字符集時，你只有BINARY方式的排序可以
選擇。 問題是，如果一個早期應(yīng)該使用CP850+大小寫不敏感方式的排序，在升級到新的字符集+BINARY排序時，程序中的大小寫要改成敏感的。 類似的問題可以通過修改SYBASE的相應(yīng)字符集下的排序文件解決。你甚至可以定義自己的排序方式。 首先我們來看看GB18030字符集的BINARY排序。BINARY排序?qū)?yīng)的是$SYB_HOME/charsets/gb18030/binary.srt，用文本編輯器打開這個文件，可以看到其內(nèi)容如下：
1 ; semi-colon is the comment character
2[sortorder]

5; Sort Order Overview:
6; --------------------
7; Based on the gb18030 simplified Chinese character set, this sort
8; order is a binary ordering.
9;
10;===============================================================================
11
12class = 0x01 ; Class `1' sort order
13id = 0x32 ; id = 50
14name = bin_gb18030
15menuname = "Binary ordering, for gb18030."
16charset = gb18030
17
18description = "Binary sort order for simplified Chinese using gb18030."
19
20binary = "true"
21 Class、id、name、menuname、charset、description都不用修改，而binary=true則指明使用binary方式排序，其實這句等價于對01~FF每個字符都進行定義。 其
次，看一下其他字符集中的大小寫不敏感的排序文件，如$SYB_HOME/charsets/iso_1/noaccents.srt，具體內(nèi)容就不寫
了。可以發(fā)現(xiàn)大小寫不敏感只是設(shè)置a, A；b, B等字符相等。參考這個排序文件，我們就可以這樣定義binary.srt： 1. 設(shè)置a=A...z=Z； 2. 定義其他字符。 這樣修改之后，就支持GB18030下的大小寫不敏感排序了。 修改排序文件后，需要使用加裁該字符集和排序： charset -Usa -Ppassword -Sserver sort_order_file charset_name 然后在isql中用sp_configure 'default sortorder id', 文件中的id（十進制），兩次重啟SYBASE后修改字符集排序就完成了。
這種方法適用于ASE11.9.2~15.0各個版本，經(jīng)歷了實踐考驗。
另外對于早期版本，沒有CP936和GB18030，可以從15.0拷一個過去用。 下面附上我修改的GB18030, BINARY.SRT文件內(nèi)容：
1; semi-colon is the comment character
