如果您使用的是Windows，您可以在批处理文件中使用以下循环完成此任务。

set database=YOURDATABASENAME
for /F "tokens=1 skip=1 usebackq" %%a in (`mysql %%database%% -e "show table status where Engine != 'InnoDB';"`) do (
    mysql %database% -e "ALTER TABLE %%a ENGINE = 'InnoDB';"
)

只需将YOURDATABASENAME更改为目标数据库的名称，或者使用%~1通过命令行传递数据库名称。

所有当前不是InnoDB的表都将被转换为InnoDB。如果您像问题所建议的那样专门针对MyISAM，下面的代码有一个仅针对MyISAM的更新的MySQL条件。

set database=YOURDATABASENAME
for /F "tokens=1 skip=1 usebackq" %%a in (`mysql %%database%% -e "show table status where Engine = 'MyISAM';"`) do (
    mysql %database% -e "ALTER TABLE %%a ENGINE = '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

在下面的脚本中，用特定的数据替换<用户名>、<密码>和<模式>。

要显示可以复制粘贴到mysql客户端会话的语句，输入以下命令:

echo 'SHOW TABLES;' \
 | mysql -u <username> --password=<password> -D <schema> \
 | awk '!/^Tables_in_/ {print "ALTER TABLE `"$0"` ENGINE = InnoDB;"}' \
 | column -t \

要简单地执行更改，使用以下命令:

echo 'SHOW TABLES;' \
 | mysql -u <username> --password=<password> -D <schema> \
 | awk '!/^Tables_in_/ {print "ALTER TABLE `"$0"` ENGINE = InnoDB;"}' \
 | column -t \
 | mysql -u <username> --password=<password> -D <schema>

遵循步骤:

Use MySql commands as follows, for converting to InnoDB (ALTER TABLE t1 ENGINE = InnoDB) or (ALTER TABLE t1 ENGINE = MyISAM) for MyISAM (You should do this for each individual tables, t1 is for the table name.). Write a script that loops on all tables and run the alter command Use an already available script to handle that: https://github.com/rafihaidari/convert-mysql-tables-storage-engine Try this SQL to Get all info will get all the tables information then you can change all the table from isam to InnoDB SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') FROM INFORMATION_SCHEMA.TABLES WHERE ENGINE='MyISAM' AND table_schema = 'your_DB_Name';

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

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
