#1
select name from vocubulary where vid not in (select vid from collapse_menu)
从vocubulary中选择名称,其中vid不在(从collapse_menu中选择vid)
#2
I assume that you are asking for the those names in vocabulary, where the vid is not in the collapse_menu table.
我假设您要求在词汇表中使用这些名称,其中vid不在collapse_menu表中。
In which case
在这种情况下
SELECT name
FROM vocabulary
LEFT JOIN collapse_menu ON vocabulary.vid = collapse_menu.vid
WHERE collapse_menu.vid IS NULL
#3
SELECT * FROM vocabulary, collapse_menu WHERE vocabulary.vid <> collapse_menu.vid;
SELECT * FROM词汇表,collapse_menu WHERE vocabulary.vid <> collapse_menu.vid;
#4
select name
from vocabulary as v,
collapse_menu as c
where v.vid!=c.vid
