sql - 如何相交 2 个子查询

问题描述

您好，我想将 2 个长查询彼此相交，但我发现您只能与简单查询相交。这有可能得到这样的东西吗？

`SELECT id, name as antibodyName FROM Antibodies WHERE
                id IN 
                ((SELECT id FROM Antibodies WHERE name LIKE ?
                UNION all
                SELECT antiId FROM AssignedColors WHERE name LIKE ?
                UNION all
                SELECT antiId FROM AssignedReactivities WHERE name LIKE ?)
                INTERSECT
                (SELECT id FROM Antibodies WHERE name LIKE ?
                  UNION all
                  SELECT antiId FROM AssignedColors WHERE name LIKE ?
                  UNION all
                  SELECT antiId FROM AssignedReactivities WHERE name LIKE ?)
                )
                AND dateOfCreation >= ? AND dateOfCreation <= ?
                ORDER BY dateOfCreation DESC LIMIT ? OFFSET ?;`

实际上，我想获得其他查询联合的相交。

解决方案

您必须SELECT为每组联合查询使用一个语句：

SELECT id, name as antibodyName 
FROM Antibodies 
WHERE id IN (
  SELECT id FROM
  (
    SELECT id FROM Antibodies WHERE name LIKE ?
    UNION all
    SELECT antiId FROM AssignedColors WHERE name LIKE ?
    UNION all
    SELECT antiId FROM AssignedReactivities WHERE name LIKE ?
  )
  INTERSECT
  SELECT id FROM
  (
    SELECT id FROM Antibodies WHERE name LIKE ?
    UNION all
    SELECT antiId FROM AssignedColors WHERE name LIKE ?
    UNION all
    SELECT antiId FROM AssignedReactivities WHERE name LIKE ?
  )
) AND dateOfCreation >= ? AND dateOfCreation <= ?
ORDER BY dateOfCreation DESC LIMIT ? OFFSET?;
