SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') 
FROM INFORMATION_SCHEMA.TABLES
WHERE ENGINE='MyISAM'
AND table_schema = 'mydatabase';

效果非常好。

这将为您提供可以批处理运行的带有alter查询的所有表的列表

<?php

// Convert all MyISAM tables to INNODB tables in all non-special databases.
// Note: With MySQL less than 5.6, tables with a fulltext search index cannot be converted to INNODB and will be skipped.

if($argc < 4)
    exit("Usage: {$argv[0]} <host> <username> <password>\n");
$host = $argv[1];
$username = $argv[2];
$password = $argv[3];

// Connect to the database.
if(!mysql_connect($host, $username, $password))
    exit("Error opening database. " . mysql_error() . "\n");

// Get all databases except special ones that shouldn't be converted.
$databases = mysql_query("SHOW databases WHERE `Database` NOT IN ('mysql', 'information_schema', 'performance_schema')");
if($databases === false)
    exit("Error showing databases. " . mysql_error() . "\n");

while($db = mysql_fetch_array($databases))
{
    // Select the database.
    if(!mysql_select_db($db[0]))
        exit("Error selecting database: {$db[0]}. " . mysql_error() . "\n");
    printf("Database: %s\n", $db[0]);

    // Get all MyISAM tables in the database.
    $tables = mysql_query("SHOW table status WHERE Engine = 'MyISAM'");
    if($tables === false)
        exit("Error showing tables. " . mysql_error() . "\n");

    while($tbl = mysql_fetch_array($tables))
    {
        // Convert the table to INNODB.
        printf("--- Converting %s\n", $tbl[0]);
        if(mysql_query("ALTER TABLE `{$tbl[0]}` ENGINE = INNODB") === false)
            printf("--- --- Error altering table: {$tbl[0]}. " . mysql_error() . "\n");
    }
}

mysql_close();

?>

下面是一个为Django用户提供的方法:

from django.core.management.base import BaseCommand
from django.db import connections


class Command(BaseCommand):

    def handle(self, database="default", *args, **options):

        cursor = connections[database].cursor()

        cursor.execute("SHOW TABLE STATUS");

        for row in cursor.fetchall():
            if row[1] != "InnoDB":
                print "Converting %s" % row[0],
                result = cursor.execute("ALTER TABLE %s ENGINE=INNODB" % row[0])
                print result

将它添加到你的应用程序的文件夹管理/命令/下，然后你可以用manage.py命令转换所有的表:

python manage.py convert_to_innodb

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

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;"

cd / var / lib / mysql / DBNAME

Ls | grep ".frm" | cut -d"."-f1 | xargs -I{} -n1 mysql -D DBNAME -e "alter table {} ENGINE=INNODB;"-uroot -pXXXXX
