要为所有非系统模式中的所有表生成ALTER语句，按这些模式/表排序，运行以下命令:

SELECT  CONCAT('ALTER TABLE ',TABLE_SCHEMA,'.', table_name, ' ENGINE=InnoDB;') AS sql_statements
FROM    information_schema.tables
WHERE   TABLE_SCHEMA NOT IN ('mysql', 'information_schema', 'performance_schema', 'innodb', 'sys', 'tmp')
AND     `ENGINE` = 'MyISAM'
AND     `TABLE_TYPE` = 'BASE TABLE'
ORDER BY TABLE_SCHEMA, table_name DESC;

之后，通过客户端运行这些查询来执行修改。

答案基于上述答案，但改进了模式处理。

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;

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

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';"
)

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';

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。
