试试这个shell脚本

DBENGINE='InnoDB' ;
DBUSER='your_db_user' ;
DBNAME='your_db_name' ;
DBHOST='your_db_host'
DBPASS='your_db_pass' ;
mysqldump --add-drop-table -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME > mtest.sql; mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "SHOW TABLES;" | while read TABLE ; do mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "ALTER TABLE $TABLE ENGINE=$DBENGINE;" ; done

试试这个shell脚本

DBENGINE='InnoDB' ;
DBUSER='your_db_user' ;
DBNAME='your_db_name' ;
DBHOST='your_db_host'
DBPASS='your_db_pass' ;
mysqldump --add-drop-table -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME > mtest.sql; mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "SHOW TABLES;" | while read TABLE ; do mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "ALTER TABLE $TABLE ENGINE=$DBENGINE;" ; done

mysqli连接;

<?php

$host       = "host";
$user       = "user";
$pass       = "pss";
$database   = "db_name";


$connect = new mysqli($host, $user, $pass, $database);  

// Actual code starts here Dont forget to change db_name !!
$sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_SCHEMA = 'db_name' 
    AND ENGINE = 'MyISAM'";

$rs = $connect->query($sql);

while($row = $rs->fetch_array())
{
    $tbl = $row[0];
    $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
    $connect->query($sql);
} ?>

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

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

对这个util脚本的一些修复

SET @DATABASE_NAME = 'Integradb';

SELECT  CONCAT('ALTER TABLE ', table_schema, '.', table_name, ' ENGINE=InnoDB;') AS sql_statements
FROM    information_schema.tables AS tb
WHERE   table_schema = @DATABASE_NAME
AND     `ENGINE` = 'MyISAM'
AND     `TABLE_TYPE` = 'BASE TABLE'
ORDER BY table_name DESC;
