View as plain text  
Are you just trying to copy a subset of one table into another? If so, simply 
do this:

CREATE TABLE new_one SELECT * FROM old_one LIMIT 1000,5000;

That will create a table with the same columns, but no keys or such. If you 
want to copy the key structure, it will take you two commands:

CREATE TABLE new_one LIKE old_one;
INSERT INTO new_one SELECT * FROM old_one LIMIT 1000,5000;

If you want a random selection (say 1% of your original records), use

... WHERE RAND() < .01;
