In addition: CREATE TABLE new_table AS SELECT * FROM old_table LIMIT 0; -- also gets you a clone w/ no data In 8.3 the (LIKE ...) construct allows for creation of indexes; in earlier versions I think they have to be done manually if they are desired. I think though that populating the table w/ indexes from a LIKE command would need an extra step to load data [which seems odd, seems it much faster usually to load data and then create indexes, etc.].
