Mongodb – How to rename a MongoDB database

databasemongodb

There's a typo in my MongoDB database name and I'm looking to rename the database.

I can copy and delete like so…

db.copyDatabase('old_name', 'new_name');
use old_name
db.dropDatabase();

Is there a command to rename a database?

Best Answer

You could do this:

db.copyDatabase("db_to_rename","db_renamed","localhost")
use db_to_rename
db.dropDatabase();

Editorial Note: this is the same approach used in the question itself but has proven useful to others regardless.

Mysql – How to quickly rename a MySQL database (change schema name)

For InnoDB, the following seems to work: create the new empty database, then rename each table in turn into the new database:

RENAME TABLE old_db.table TO new_db.table;

You will need to adjust the permissions after that.

For scripting in a shell, you can use either of the following:

mysql -u username -ppassword old_db -sNe 'show tables' | while read table; \ 
    do mysql -u username -ppassword -sNe "rename table old_db.$table to new_db.$table"; done

for table in `mysql -u root -ppassword -s -N -e "use old_db;show tables from old_db;"`; do mysql -u root -ppassword -s -N -e "use old_db;rename table old_db.$table to new_db.$table;"; done;

Notes:

There is no space between the option -p and the password. If your database has no password, remove the -u username -ppassword part.
If some table has a trigger, it cannot be moved to another database using above method (will result Trigger in wrong schema error). If that is the case, use a traditional way to clone a database and then drop the old one:

mysqldump old_db | mysql new_db
If you have stored procedures, you can copy them afterwards:

mysqldump -R old_db | mysql new_db
