输入mysql -uroot 回车进入脚本模式
再打开一个黑色窗口输入mysql -uroot<要打开的脚本文件
之后就可以用sql语句进行增删改查 *** 作了
1.打开终端,输入: cd ~会进入~文件夹
2.然后输入:touch .bash_profile
回车执行后,
2.再输入:open -e .bash_profile
会在TextEdit中打开这个文件(如果以前没有配置过环境变量,那么这应该是一个空白文档)。如果有内容,请在结束符前输入,如果没有内容,请直接输入如下语句:
export PATH=${PATH}:/usr/local/mysql/bin
然后,保存,退出TextEdit(一定是退出),关闭终端并退出。
如果您觉得文本对您有帮助,请打赏,谢谢。
