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>';
    }

一个简单的MySQL版本。

你可以简单地启动mysql可执行文件，使用数据库和复制粘贴查询。

这将把当前数据库中的所有MyISAM表转换为INNODB表。

DROP PROCEDURE IF EXISTS convertToInnodb;
DELIMITER //
CREATE PROCEDURE convertToInnodb()
BEGIN
mainloop: LOOP
  SELECT TABLE_NAME INTO @convertTable FROM information_schema.TABLES
  WHERE `TABLE_SCHEMA` LIKE DATABASE()
  AND `ENGINE` LIKE 'MyISAM' ORDER BY TABLE_NAME LIMIT 1;
  IF @convertTable IS NULL THEN 
    LEAVE mainloop;
  END IF;
  SET @sqltext := CONCAT('ALTER TABLE `', DATABASE(), '`.`', @convertTable, '` ENGINE = INNODB');
  PREPARE convertTables FROM @sqltext;
  EXECUTE convertTables;
  DEALLOCATE PREPARE convertTables;
  SET @convertTable = NULL;
END LOOP mainloop;

END//
DELIMITER ;

CALL convertToInnodb();
DROP PROCEDURE IF EXISTS convertToInnodb;

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;

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';

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。

当表很大时，最好从控制台进行操作

convert-to-innodb.sh

#!/usr/bin/env bash

# Usage: ./convert-to-innodb.sh 'db' 'user' 'password' | mysql 'db' -u  user -p password


set -eu

db="$1"
user="$2"
pass="$3"


sql="SET @DATABASE_NAME = '${db}';"

sql+="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;"

echo $sql | mysql -u${user} -p${pass} | tail -n +2
