Nice one Julz

Yes if you want to do more than simply backup the table data and want to actually make a proper fully functional copy of the table then the above is definitely the best way to do so.

To do this you have to use: CREATE TABLE new_table_name LIKE old_table_name; then you populate it with the data from the old table with: INSERT INTO new_table_name SELECT * FROM old_table_name; If the copied old table has many keys then it may help to speed the INSERT if you turn off the keys using the following before the INSERT: ALTER TABLE new_table_name DISABLE KEYS; And then after the INSERT: ALTER TABLE new_table_name ENABLE KEYS; These two statements are not supported by all MySQL Engine types though. InnoDB being one of them in MySQL ver 5.x Cheers Julz Just remember that this won't create the table using the same engine as the existing table and it won't recreate the primary keys or indexes.

CREATE TABLE new_table_name LIKE old_table_name;

INSERT INTO new_table_name SELECT * FROM old_table_name;

If the copied old table has many keys then it may help to speed the INSERT if you turn off the keys using the following before the INSERT:

ALTER TABLE new_table_name DISABLE KEYS;

And then after the INSERT:

ALTER TABLE new_table_name ENABLE KEYS;
