如何将mysql数据库中的MyISAM类型表更改成InnoDB类型的表mysql

改单个表sql

ALTER TABLE TABLENAME ENGINE=InnoDB;
ALTER TABLE TABLENAME ENGINE=MyISAM;

改多个表数据库

#修改成InnoDB

SELECT CONCAT( 'ALTER TABLE ', TABLE_NAME, ' ENGINE=InnoDB;' )
FROM information_schema.tables
WHERE table_schema = 'DBNAME'
LIMIT 0 , 10000;

　#修改成MyISAM编码

SELECT CONCAT( 'ALTER TABLE ', TABLE_NAME, ' ENGINE=MyISAM;' ) FROM information_schema.tables WHERE table_schema = 'DBNAME' LIMIT 0 , 10000;

使用说明：spa

1. 将以上SQL语句中的 DBNAME 替换成须要修改的数据库名称。code

2. 执行SQL，这个时候尚未修改，只是给了一个查询结果。orm

3. 将查询结果复制，去掉先后的引号，而后执行。blog

批量修改mysql数据库字符集ip

ALTER DATABASE DBNAME DEFAULT CHARACTER SET='utf8';

mysql数据库表字段乱码，链接数据库时设置正确的编码便可ci

mysql_query('set names utf8');

Mysql修改表、字段、库的字符集

ALTER DATABASE `zc139` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

ALTER TABLE `news_articles` ENGINE=INNODB;
ALTER TABLE `news_articles_text` ENGINE=INNODB;
ALTER TABLE `news_authors` ENGINE=INNODB;
ALTER TABLE `news_comments` ENGINE=INNODB;
ALTER TABLE `news_comments_description` ENGINE=INNODB;
ALTER TABLE `popular_searches` ENGINE=INNODB;
ALTER TABLE `un_products_to_wishlists` ENGINE=INNODB;
ALTER TABLE `un_wishlists` ENGINE=INNODB;


ALTER TABLE `news_articles` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
ALTER TABLE `news_articles_text` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
ALTER TABLE `news_authors` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
