如何將mysql數據庫中的MyISAM類型表更改成InnoDB類型的表mysql

改單個表sql

ALTER TABLE TABLENAME ENGINE=InnoDB;
ALTER TABLE TABLENAME ENGINE=MyISAM;

改多個表數據庫

#修改成InnoDB

SELECT CONCAT( 'ALTER TABLE ', TABLE_NAME, ' ENGINE=InnoDB;' )
FROM information_schema.tables
WHERE table_schema = 'DBNAME'
LIMIT 0 , 10000;

　#修改成MyISAM編碼

SELECT CONCAT( 'ALTER TABLE ', TABLE_NAME, ' ENGINE=MyISAM;' ) FROM information_schema.tables WHERE table_schema = 'DBNAME' LIMIT 0 , 10000;

使用說明：spa

1. 將以上SQL語句中的 DBNAME 替換成須要修改的數據庫名稱。code

2. 執行SQL，這個時候尚未修改，只是給了一個查詢結果。orm

3. 將查詢結果複製，去掉先後的引號，而後執行。blog

批量修改mysql數據庫字符集ip

ALTER DATABASE DBNAME DEFAULT CHARACTER SET='utf8';

mysql數據庫表字段亂碼，鏈接數據庫時設置正確的編碼便可ci

mysql_query('set names utf8');

Mysql修改表、字段、庫的字符集

ALTER DATABASE `zc139` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
