SQLite多条件

假设我有一个名为“水果”的下表，其中有字段“水果”、“状态”和“日期”

如何查询已“添加”和“删除”的所有水果

您需要一个自联接：

SELECT DISTINCT added.FRUIT
FROM fruits AS added
INNER JOIN fruits AS removed
  ON added.FRUIT=removed.FRUIT
WHERE added.STATUS="ADDED"
AND removed.STATUS="REMOVED"

这将找到共享水果且具有正确状态的所有行对

你尝试了什么？我想你可能需要加入水果类型

内部加入水果，因为在移除时移除了水果。水果=添加。水果

@克里斯在你评论时添加了这一点。谢谢你的回答！

SELECT DISTINCT added.FRUIT
FROM fruits AS added
INNER JOIN fruits AS removed
  ON added.FRUIT=removed.FRUIT
WHERE added.STATUS="ADDED"
AND removed.STATUS="REMOVED"
