Error dropping database in SQL (can't rmdir './tract', errno: 66)

Question

I am trying to drop the database and create it again, obviously, but it will not work.

It gives me the error:

---

mysql> source /Users/divinedavis/downloads/tract_schema.sql;

ERROR 1010 (HY000): Error dropping database (can't rmdir './tract', errno: 66)

ERROR 1010 (HY000): Can't creat database 'TRACT'; database exits

Database changed

DROP DATABASE IF EXISTS TRACT;
CREATE DATABASE TRACT;
USE TRACT;

Solution 1

Find the DB directory first using command

mysql -e "select @@datadir"

It will return your database directory e.g.

+-----------------------+
| @@datadir             |
+-----------------------+
| /usr/local/var/mysql/ |
+-----------------------+

Goto that directory and delete the database using command

rm -rf DB_name

You can root user too using command

sudo rm -rf DB_name

Solution 2

It looks like you may have lost some files, which would explain why mysql says the db exists, but you can't delete it due to file not found errors.

There are entries in the system db for database objects and if some files go away (are deleted or whatever) you can't just DROP [database] if this happens.

Check here for the answer.

Solution 3

Please take a look at this post:

how to drop database

Seems that there are some not mysql files inside tract directory.

Be careful. You may delete some important files which are unrelated to mysql.

I'm using Mac. Is there a way I can delete it through the finder?

How did he get this sh-3.2# ls -la data/test total 0 drwxr-xr-x 3 _mysql wheel 102 Apr 15 12:36 . drwxr-xr-x 11 _mysql wheel 374 Apr 15 12:28 .. -rw-r--r-- 1 _mysql wheel 0 Mar 31 10:19 .empty to pop up?

You should first check what files are on that directory, before removing it.
