在mysql中，你可以使用文本编辑器进行搜索/替换:

SELECT table_schema, table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

注意:你可能应该忽略information_schema和mysql，因为“mysql和information_schema数据库，实现了一些mysql内部，仍然使用MyISAM。特别是，你不能切换授权表来使用InnoDB。”(http://dev.mysql.com/doc/refman/5.5/en/innodb-default-se.html)

在任何情况下，请注意要忽略并运行的表:

SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

现在只需复制/粘贴列表到你的文本编辑器，搜索/替换“|”与“ALTER TABLE”等。

然后你会有一个这样的列表，你可以简单地粘贴到你的mysql终端:

ALTER TABLE arth_commentmeta           ENGINE=Innodb;
ALTER TABLE arth_comments              ENGINE=Innodb;
ALTER TABLE arth_links                 ENGINE=Innodb;
ALTER TABLE arth_options               ENGINE=Innodb;
ALTER TABLE arth_postmeta              ENGINE=Innodb;
ALTER TABLE arth_posts                 ENGINE=Innodb;
ALTER TABLE arth_term_relationships    ENGINE=Innodb;
ALTER TABLE arth_term_taxonomy         ENGINE=Innodb;
ALTER TABLE arth_terms                 ENGINE=Innodb;
ALTER TABLE arth_usermeta              ENGINE=Innodb;

如果你的文本编辑器不能很容易地做到这一点，这里有另一个解决方案，为一个类似的列表(你可以粘贴到mysql)，你的数据库只有一个前缀，从linux终端:

mysql -u [username] -p[password] -B -N -e 'show tables like "arth_%"' [database name] | xargs -I '{}' echo "ALTER TABLE {} ENGINE=INNODB;"

您可以用您最喜欢的脚本语言编写一个脚本来完成它。该脚本将执行以下操作:

Issue显示满表。对于返回的每一行，检查第二列是否显示为“BASE TABLE”而不是“VIEW”。如果它不是'VIEW'，发出适当的ALTER TABLE命令。

一行:

 mysql -u root -p dbName -e 
 "show table status where Engine='MyISAM';" | awk 
 'NR>1 {print "ALTER TABLE "$1" ENGINE = InnoDB;"}'  | 
  mysql -u root -p dbName

<?php
    // connect your database here first 
    // 

    // Actual code starts here 

    $sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
        WHERE TABLE_SCHEMA = 'your_database_name' 
        AND ENGINE = 'MyISAM'";

    $rs = mysql_query($sql);

    while($row = mysql_fetch_array($rs))
    {
        $tbl = $row[0];
        $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
        mysql_query($sql);
    }
?>

这很简单。只有两步。

复制，粘贴并运行: SET @DATABASE_NAME = ' name_your_db '; SELECT CONCAT('ALTER TABLE "， table_name， ' ENGINE=InnoDB;') AS sql_statements FROM information_schema。TABLE AS tb WHERE ' ENGINE ' = 'MyISAM' AND ' TABLE_TYPE ' = 'BASE TABLE'

(复制粘贴所有结果在SQL选项卡)

将所有结果复制到SQL选项卡并在下面一行中粘贴。 开始事务; 提交;

例如:

START TRANSACTION;
ALTER TABLE `admin_files` ENGINE=InnoDB;
COMMIT;
