Hi
Can you tell me what I've done wrong writting that base.
Queries doesn't work.
That's bash script code which makes tah base

Assuming you're doing these in this order, this can't
succeed.  LECZENIE referenes WIZYTY which isn't
created yet as do some other tables, which causes
those tables not to exist later when you reference
them.  If you want to make circular trees of references
you need to use ALTER TABLE ADD CONSTRAINT to
add the foreign key constraints after the create
tables.
