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';

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;

对这个util脚本的一些修复

SET @DATABASE_NAME = 'Integradb';

SELECT  CONCAT('ALTER TABLE ', table_schema, '.', 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;

我是一个新手，必须找到自己的解决方案，因为网上的mysql命令通常充满了拼写错误，这对刚开始使用的人来说是一个现实生活的噩梦。这是我的解决方案....

我用excel一次准备了几十个命令(可以复制和粘贴)，而不是每个表一个命令。

How? expand your putty window and enter mysql and then run the command "SHOW TABLE STATUS;" and the copy/paste the output to microsoft excel. Go to the Data tab and use the "text to columns" feature an delimit the columns by a space key. Then Sort the columns by whichever column shows your table types and delete all rows which the tables are already in InnoDb format (because we don't need to run commands against them, they are already done). Then add 2 columns to the left of the tables column, and 2 columns to the right. Then paste in the first part of the command in column-1 (see below). Column 2 should contain only a space. Column 3 is your tables column. Column 4 should contain only a space. Column 5 is the last part of your command. It should look like this:

column-1        column-2            column-3         column-4     column-5
ALTER TABLE     t_lade_tr           ENGINE=InnoDB;
ALTER TABLE     t_foro_detail_ms    ENGINE=InnoDB;
ALTER TABLE     t_ljk_ms            ENGINE=InnoDB;

然后每次复制粘贴5行到mysql中。这将一次转换大约5个。我注意到，如果我一次做了更多的操作，那么命令就会失败。

在我的例子中，我从一个默认MyISAM的MySQL实例迁移到一个默认InnoDB的MariaDB实例。

根据MariaDB迁移文件。

在旧服务器上运行:

mysqldump -u root -p --skip-create-options --all-databases > migration.sql

——skip-create-options确保数据库服务器在加载数据时使用默认存储引擎，而不是MyISAM。

mysql -u root -p < migration.sql

这抛出了一个关于创建mysql.db的错误，但现在一切都很好了:)

<?php
    // connect your database here first 
    // 

    // Actual code starts here 

    $sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
        WHERE TABLE_SCHEMA = 'your_database_name' 
        AND ENGINE = 'MyISAM'";

    $rs = mysql_query($sql);

    while($row = mysql_fetch_array($rs))
    {
        $tbl = $row[0];
        $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
        mysql_query($sql);
    }
?>
