mysql - How to set the default collation of a table?

Question

I am asked to set all table's default COLLATE to utf8_bin. How to do this?

Answer 1

        ALTER TABLE <table name> COLLATE utf8_bin;

如果您还需要更新现有的字符编码（不太可能通过事物的声音），您可以使用：

      ALTER TABLE <table name> CONVERT TO CHARACTER SET utf8 COLLATE utf8_bin;

Answer 2

这个怎么做？

一次一个，恐怕...

alter table <some_table> convert to character set utf8 collate utf8_bin;

没有批量方法，除非您想使用mysqldump来获取整个数据库，否则编辑生成的转储以添加所需的排序规则，然后再次重新导入整个数据库。

Answer 3

SELECT CONCAT("ALTER TABLE ", TABLE_NAME," COLLATE utf8_bin") AS    String
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="YourDatabaseName"
AND TABLE_TYPE="BASE TABLE"

一个查询统治所有，只需运行此查询的结果。
