在下面的脚本中，用特定的数据替换<用户名>、<密码>和<模式>。

要显示可以复制粘贴到mysql客户端会话的语句，输入以下命令:

echo 'SHOW TABLES;' \
 | mysql -u <username> --password=<password> -D <schema> \
 | awk '!/^Tables_in_/ {print "ALTER TABLE `"$0"` ENGINE = InnoDB;"}' \
 | column -t \

要简单地执行更改，使用以下命令:

echo 'SHOW TABLES;' \
 | mysql -u <username> --password=<password> -D <schema> \
 | awk '!/^Tables_in_/ {print "ALTER TABLE `"$0"` ENGINE = InnoDB;"}' \
 | column -t \
 | mysql -u <username> --password=<password> -D <schema>

<?php

  // connect your database here first

  mysql_connect('host', 'user', 'pass');

  $databases = mysql_query('SHOW databases');

  while($db = mysql_fetch_array($databases)) {
    echo "database => {$db[0]}\n";
    mysql_select_db($db[0]);

    $tables = mysql_query('SHOW tables');

    while($tbl = mysql_fetch_array($tables)) {
      echo "table => {$tbl[0]}\n";
      mysql_query("ALTER TABLE {$tbl[0]} 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。

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。

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>';
    }
