The concept of rows is _the result of your SQL query_. Learn about the
SELECT statement in SQL. The general form is
select [columns...] from <table> where [conditions...]
select * from my_stuff # returns all rows and cols
select id, name, date from my_stuff # returns 3 cols and all rows
select id, name, date from my_stuff limit 1 # returns 3 cols and 1 row
select id, name, date from my_stuff order by name limit 1 # returns 1
row, based on sort
select id, name, date from my_stuff where id = 12345 # returns this
specific row
