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。

<?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();

?>

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。

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

cd / var / lib / mysql / DBNAME

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