I'm getting some weird results, so I need to just check myself...
我得到了一些奇怪的结果,所以我需要检查自己......
SELECT *
FROM table
WHERE complete != 0
AND pending != 1
To be clear, these are allowed:
需要说明的是,这些是允许的:
pending = 0, complete = 0
pending = 1, complete = 1
pending = 0, complete = 1
THis is NOT allowed to be returned from my query:
不允许从我的查询中返回:
pending = 1, complete = 0
What am I missing here...?
我在这里想念的是什么......?

Try:
尝试:
SELECT *
FROM table
WHERE NOT (complete = 0
AND pending = 1)
or
要么
SELECT *
FROM table
WHERE !(complete = 0
AND pending = 1)

You need to use OR
, not AND
. Your expression leaves out any combination where complete = 0
or pending = 1
, which is too restrictive. Try the following:
你需要使用OR,而不是AND。你的表达式中没有完成= 0或pending = 1的任何组合,这是限制性太强。请尝试以下方法:
SELECT *
FROM Table
WHERE complete != 0 OR pending != 1;
^^ change AND to OR
