Question

I am trying to change the data directory of a MySQL table using the following command. I am trying in windows. But it is not working. Can somebody tell me the reason?

CREATE TABLE clients
(
  client_id INT AUTO_INCREMENT KEY, 
  client_name VARCHAR(75), 
  telephone CHAR(15)
)
DATA DIRECTORY = 'e:\data\mysql';

The table is created. But it is created in the default data directory.

Per the documentation:

These options work only when you are not using the –skip-symbolic-links option. Your operating system must also have a working, thread-safe realpath() call. See Section 7.9.6.2, “Using Symbolic Links for Tables on Unix”, for more complete information.

Windows does not have a working, thread-safe realpath() call, so you can’t do this.
