我有一个名为PM_BATCH_ST的表,如下所示:
| 批次ID|结果|
| --|--|
| 1000564932 |ISC|
| 1000564932 |LLC|
| 1000585739 |ISC|
| 1000585739 |LLC|
| 1000384769 |ISC|
| 1000384769 |LLC|
| 1000384757 |LLC|
| 1000888940 |ISC|
我是否可以过滤表以获得同时具有ISC条目和LLC条目的BATCH_ID?我想要的答案是:
1000564932
1000585739
1000384769

SELECT BATCH_ID
FROM PM_BATCH_ST
WHERE RESULT IN ('ISC', 'LLC')
GROUP BY BATCH_ID
HAVING COUNT(DISTINCT RESULT) = 2;

我认为以下内容可以:

select distinct batch_id
from  PM_BATCH_ST a
where a.result = 'ISC' and 
  exists (
    select 1
    from  PM_BATCH_ST b
    where a.batch_id=b.batch_id 
      and b.result='LLC'
  )

这可以通过INTERSECT来实现

SELECT BATCH_ID
FROM PM_BATCH_ST
WHERE RESULT = 'ISC'

INTERSECT

SELECT BATCH_ID
FROM PM_BATCH_ST
WHERE RESULT = 'LLC'

测试结果:

BATCH_ID
1000384769
1000564932
1000585739

对于2个值,我只需要self-JOIN并使用WHERE子句,如下所示:

SELECT st1.BATCH_ID
FROM PM_BATCH_ST st1
JOIN PM_BATCH_ST st2 ON st1.BATCH_ID = st2.BATCH_ID
WHERE st1.RESULT = 'ISC' AND st2.RESULT = 'LLC'

这应该给予所有BATCH_ID,同时具有ISCLLC,作为RESULT

| 1000585739 |

CREATE TABLE PM_BATCH_ST (
    BATCH_ID INT,
    RESULT TEXT
);

INSERT INTO PM_BATCH_ST (BATCH_ID, RESULT)
VALUES
    (1000564932, 'ISC'),
    (1000564932, 'LLC'),
    (1000585739, 'ISC'),
    (1000585739, 'LLC'),
    (1000384769, 'ISC'),
    (1000384769, 'LLC'),
    (1000384757, 'LLC'),
    (1000888940, 'ISC');

/* @Qubicon has the most tighten-up answer. Below is another way of doing it*/

WITH ISC_table AS (
  SELECT *
  FROM PM_BATCH_ST
  WHERE CONVERT(VARCHAR, RESULT) IN ('ISC')
),
    LLC_table AS (
  SELECT *
  FROM PM_BATCH_ST
  WHERE CONVERT(VARCHAR, RESULT) IN ('LLC')
)

SELECT
  t1.BATCH_ID AS BATCH_ID
FROM ISC_table AS t1
INNER JOIN LLC_table AS t2
ON t1.BATCH_ID = t2.BATCH_ID;

| 批次ID|
| --|
| 1000564932 |
| 1000585739 |
| 1000384769 |

这是另一种方法,你可以达到预期的结果。

SELECT DISTINCT a.BATCH_ID
FROM PM_BATCH_ST a
INNER JOIN PM_BATCH_ST b ON a.BATCH_ID = b.BATCH_ID
WHERE a.RESULT = 'ISC' AND b.RESULT = 'LLC';
