在mysql中复制没有数据的数据库结构(带有空表)

2022-01-20 00:00:00 复制 database-schema mysql

有没有办法在MySQL中复制没有数据的数据库结构,所以新数据库将与复制时相同,但带有空表.

Is there any way to copy database structure without data in MySQL, so the new database will be the same as it is copied from, but with empty tables.

在得到一些建议后,我尝试了该命令,但出现语法错误,我的 username = rootpassword = nothing.我猜是默认的.我正在尝试以下命令,

After getting some suggestions I tried the command, but I am getting syntax error, my username = root and password = nothing. I guess the default one. I am trying following command,

mysqldump -u root -p -d xyz_db | mysql -u root -p -Dnew_db

我在命令中遗漏或放错了什么?

what I am missing or misplacing in command?

推荐答案

mysqldump -u user -ppass -d olddb | mysql -u user -ppass -D newdb

新数据库必须已经存在.mysqldump 命令中的 -d 标志防止复制数据.

The new database must already exist. The -d flag in the mysqldump command prevents copying of data.

-p 标志和密码之间没有空格.

There's no space between the flag -p and the password.
