Create n rows from NULL in PostgreSQL

Question

I have a table that looks like this:

id, integer, Primary Key, not null name, character varying created, timestamp without timezone, not null, default: now() 

I want to generate n lines with a NULL field name.

I know what I can do:

 INSERT INTO employee (name) VALUES (NULL), (NULL)... 

But I would rather do something like this:

 INSERT INTO employee (name) SELECT NULL FROM dummy_table_with_n_rows 

And I could choose n.

Answer 1

 INSERT INTO employee (name) SELECT NULL FROM generate_series(1,10000) i;
