如果沒有配置好cmd里面的mysql 環(huán)境變量，那就在系統(tǒng)高級(jí)設(shè)置那兒進(jìn)行MySQL的環(huán)境變量設(shè)置。

win+R，調(diào)出“運(yùn)行”，輸入cmd,回車

登錄數(shù)據(jù)庫(kù)，

查看數(shù)據(jù)庫(kù)

查看數(shù)據(jù)庫(kù)字符編碼

通過MySQL命令行修改:（編碼可選）

mysql> set character_set_client=utf8;

mysql> set character_set_connection=utf8;

mysql> set character_set_database=utf8;

mysql> set character_set_results=utf8;

mysql> set character_set_server=utf8;

mysql> set character_set_system=utf8;

mysql> set collation_connection=utf8;

mysql> set collation_database=utf8;

mysql> set collation_server=utf8;

當(dāng)然還有：

修改數(shù)據(jù)庫(kù)的字符集mysql>use mydb

mysql>alter database mydb character set utf8;

創(chuàng)建數(shù)據(jù)庫(kù)指定數(shù)據(jù)庫(kù)的字符集

mysql>create database mydb character set utf8;
