How to modify the sorting rules of an SQL table?
To change the sorting rules of an SQL table, you can use the ALTER TABLE statement with the COLLATE clause. Here are some examples:
- Change the default sorting rule of the table.
ALTER TABLE 表名
DEFAULT CHARACTER SET 字符集名称
COLLATE 排序规则名称;
- Change the sorting rules of a specific column in the table.
ALTER TABLE 表名
MODIFY 列名 数据类型
COLLATE 排序规则名称;
- Change the sorting rule of the index of the table.
ALTER TABLE 表名
ALTER INDEX 索引名
COLLATE 排序规则名称;
Please note that the specific sorting rules and character set names may vary depending on the database system you are using. Please refer to the documentation of your database system to obtain the correct sorting rules and character set names.
