mysql - 用这种方式重新命名数据库安全吗？

Question

只有数据表，没有视图
1、CREATE DATABASE new_db_name; 创建新的数据库
2、RENAME TABLE db_name.table1 TO new_db_name.table1; 对所有的表进行重命名
3、DROP DATABASE db_name; 删除原来的数据库

Answer 1

Um, can you do this? It is better to rename the database name directly.

If you want to import tables one by one from between two libraries, the standard approach is:

CREATE TABLE new_db_name.table1 LIKE db_name.table1;
INSERT INTO new_db_name.table1 SELECT * FROM db_name.table1;
