1、登陆mysql控制台
2、创建一个将整个数据库中所有表转字段换为utf-8编码的存储过程。
CREATE PROCEDURE `pr_convert_dbtab_utf8`(IN dbName varchar(100))
BEGIN
declare stop int default 0;
declare tabCount int default 0;
declare strSql varchar(1000);
declare name varchar(100);
declare cur CURSOR FOR select table_name from information_schema.tables where table_schema=dbName;
declare CONTINUE HANDLER FOR SQLSTATE '02000' SET stop = null;
OPEN cur;
FETCH cur INTO name;
WHILE ( stop is not null) DO
set tabCount=tabCount+1;
set strSql = concat('alter table `',name,'` convert to character set utf8');
set @sql1 = strSql;
prepare stmt_p from @sql1;
execute stmt_p;
FETCH cur INTO name;
END WHILE;
CLOSE cur;
SELECT concat('table: ', tabCount);
END;
转换表字段编码的sql语句为：alter table `tableName` convert to character set utf8'
3、输入调用存储过程的命令，参数为需要转换的数据库名
mysql> call pr_convert_dbtab_utf8('jiradb');
+-----------------------------+
| concat('table: ', tabCount) |
+-----------------------------+
| table: 245 |
+-----------------------------+
1 row in set
Query OK, 0 rows affected
