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';"
)

<?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();

?>

只是测试了另一种(简单的?)方法，对我来说很有效。

只需导出您的DB为.sql文件，编辑它与gedit或记事本;

将ENGINE=MyISAM替换为ENGINE=INNODB并保存已编辑的文件

编号或替换完成应该是你的表的编号

导入到MySQL (phpMyAdmin或命令行)

瞧!

对于转换MySql表存储引擎有许多方法:

使用MySql命令如下，转换为innodb (ALTER TABLE t1 ENGINE = innodb)或(ALTER TABLE t1 ENGINE = MyISAM)为MyISAM(你应该为每个单独的表这样做，t1是表名。) 编写一个在所有表上循环的脚本，并运行alter命令 使用一个已经可用的脚本来处理这个问题:https://github.com/rafihaidari/convert-mysql-tables-storage-engine

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

这是一个简单的php脚本。

<?php
    @error_reporting(E_ALL | E_STRICT);
    @ini_set('display_errors', '1');


    $con = mysql_connect('server', 'user', 'pass');
    $dbName = 'moodle2014';

    $sql = "SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$dbName."';";
    $rs = mysql_query($sql, $con);

    $count = 0;
    $ok = 0;
    while($row = mysql_fetch_array($rs)){
            $count ++;
            $tbl = $row[0];
            $sql = "ALTER TABLE ".$dbName.".".$tbl." ENGINE=INNODB;";
            $resultado = mysql_query($sql);
            if ($resultado){
                    $ok ++;
                    echo $sql."<hr/>";
            }
    }
    if ($count == $ok){
            echo '<div style="color: green"><b>ALL OK</b></div>';
    }else{
            echo '<div style="color: red"><b>ERRORS</b>Total tables: '.$count.', updated tables:'.$ok.'</div>';
    }
