mysqli连接;

<?php

$host       = "host";
$user       = "user";
$pass       = "pss";
$database   = "db_name";


$connect = new mysqli($host, $user, $pass, $database);  

// Actual code starts here Dont forget to change db_name !!
$sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_SCHEMA = 'db_name' 
    AND ENGINE = 'MyISAM'";

$rs = $connect->query($sql);

while($row = $rs->fetch_array())
{
    $tbl = $row[0];
    $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
    $connect->query($sql);
} ?>

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。

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。

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';

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;

END//
