Question

我有2张桌子

query1 table

case_no
1. 2761936
2. 2762090
3. 2762049

query_2表

case_no  lawyer_id
2762090  215444 
2762090  118999
2762049  180444

我想报告lawyer_id所在的记录＆gt; 100000和lawyer_id＆gt; = 200000 如果lawyer_id在该范围内，我根本不想要case_no。理想情况下报告应该只显示2761936和2762049

我尝试了以下方法，但它不起作用：

SELECT 
  q1.Case_no,q1.Form_no,q2.lawyer_id
FROM 
  [sample].[dbo].[Query1] Q1, 
  [sample].[dbo].[Query2] q2
where 
  q1.Case_no = q2.case_no
and q1.case_no not in(
  select 
    q1.case_no 
  from 
    [sample].[dbo].[Query2] q2
  where 
    q2.lawyer_id < 100000 and q2.lawyer_id >= 200000 )

Answer 1

根本不需要使用NOT IN子查询。使用简单的WHERE：

，您应该只需要BETWEEN子句

SELECT 
  q1.Case_no,
  q1.Form_no,
  q2.lawyer_id
FROM 
  [sample].[dbo].[Query1] Q1
  JOIN [sample].[dbo].[Query2] q2 ON q1.Case_no = q2.case_no
WHERE
  q2.lawyer_id BETWEEN 100000 AND 200000

Answer 2

由于lawyer_id永远不能同时为＆lt; 100000和200000以上你永远不会得到任何结果。

你可能想要：

q2.lawyer_id < 100000 OR q2.lawyer_id >= 200000

OR

NOT (q2.lawyer_id >= 100000 AND q2.lawyer_id <= 200000)

OR

NOT (q2.lawyer_id BETWEEN 100000 AND 200000)

我重写了你的SQL：

SELECT   A.CASE_NO,
         A.FORM_NO,
         B.LAWYER_ID
FROM     [sample].[dbo].[Query1] A,
         [sample].[dbo].[Query2] B
WHERE    A.CASE_NO = B.CASE_NO
AND      NOT (B.LAWYER_ID BETWEEN 100000 AND 200000)

Answer 3

根据您的预期结果，我推断出您想要：

所有情况
至少有一名律师身份不足100000
至少有一名律师的身份证号码大于或等于200000的案件。

在哪种情况下：

WITH query1
     AS
     (
      SELECT * 
        FROM (
              VALUES (2761936), 
                     (2762090), 
                     (2762049)
             ) AS T (case_no)
     ),
     query2
     AS
     (
      SELECT * 
        FROM (
              VALUES (2762090, 215444),
                     (2762090, 118999),
                     (2762049, 180444)
             ) AS T (case_no, lawyer_id)
     )

SELECT case_no 
  FROM query1 -- sample.dbo.query1
EXCEPT
SELECT case_no 
  FROM query2 -- sample.dbo.query2
 WHERE lawyer_id < 100000 
EXCEPT
SELECT case_no 
  FROM query2 -- sample.dbo.query2
 WHERE lawyer_id >= 200000;

也许你想要重构查询，例如

SELECT case_no 
  FROM query1 -- sample.dbo.query1
EXCEPT
SELECT case_no 
  FROM query2 -- sample.dbo.query2
 WHERE ( lawyer_id < 100000 
         OR lawyer_id >= 200000 );
