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;

运行此SQL语句(在MySQL客户端、phpMyAdmin或任何地方)检索数据库中的所有MyISAM表。

将name_of_your_db变量的值替换为您的数据库名称。

SET @DATABASE_NAME = 'name_of_your_db';

SELECT  CONCAT('ALTER TABLE `', 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;

然后，复制输出并作为一个新的SQL查询运行。

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

<?php

// Convert all MyISAM tables to INNODB tables in all non-special databases.

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();
