SELECT CONCAT('ALTER TABLE ',TABLE_NAME,' ENGINE=InnoDB;') 
FROM INFORMATION_SCHEMA.TABLES
WHERE ENGINE='MyISAM'
AND table_schema = 'mydatabase';

效果非常好。

这将为您提供可以批处理运行的带有alter查询的所有表的列表

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 

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

创建数据库的SQL转储文件(database_dump.sql)，并在记事本中打开它。 将所有“ENGINE=MyISAM”替换为“ENGINE=InnoDB”。 保存文件并将其导入数据库。

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';

在phpMyAdmin中使用此sql查询

SELECT CONCAT('ALTER TABLE ',table_schema,'.',table_name,' engine=InnoDB;') 
FROM information_schema.tables 
WHERE engine = 'MyISAM';
