从 SQL shell 脚本插入

Question

晚上好

我正在尝试在我的脚本中将数据从一个表插入到另一个表，但结果是找不到数据库 - 我做错了什么吗？

mysql -e INSERT INTO mysql.db SELECT * from "$cpuser"_mysql.db;

CPUser 是在脚本前面手动分配的变量。

从 CLI 我可以 select * 来自两个

Answer 1

-se 需要一个字符串，所以你需要提供一个

mysql -e "INSERT INTO mysql.db SELECT * from `${cpuser}_mysql`.db;" 

或者

mysql -e "INSERT INTO mysql.db SELECT * from ${cpuser}_mysql.db;" 

如果没有保留文本
