Windows下永久解決數據庫亂碼 utf8 轉 gbk

產生亂碼原因

因為windows終端的默認字符集是gbk編碼，而mysql數據庫是utf8的編碼，所以會產生亂碼問題

解決亂碼問題（臨時修改）

詢當前數據庫默認編碼：

mysql> show variables like 'character%';

修改為gbk編碼：

mysql> set names gbk;

但是這只是臨時修改，對新開啟的終端無效。

解決亂碼問題（永久）

修改MySQL的配置文件：my-default.ini

配置文件位於MySQL的安裝目錄

例如我的：C:\Program Files\MySQL\MySQL Server 5.7

[mysqld]character-set-server=gbk

[mysqld]character-set-server=gbk

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
