私は現在、selectステートメント内でselectステートメントを使用しようとしています。これまでのところ素晴らしいです。しかし、私はそれがいくつかの条件によって異なるものを選択したい。私の問題は、WHEN部分ではなく、CASE文のTHEN部分にSQL文サブクエリを置くことです。だから私の例はhereです。だから私はすべてのサブクエリでwrapedされているCASE文の中にselect文を配置したい。また、私はここではSQL Server 2008のselect文をcase文に入れることはできますか？
を使用していますことは、私が元々持っていたものです：
SELECT DISTINCT
WORK_ORDER.PART_ID,
OPERATION.SEQUENCE_NO,
OPERATION.RESOURCE_ID,
OPERATION.SETUP_HRS,
OPERATION.RUN_HRS,
OPERATION.OPERATION_TYPE,
OPERATION.RUN AS PCS_HR,
REPLACE(CONVERT(VARCHAR(150), CONVERT(BINARY(150), OPERATION_BINARY.BITS)), CHAR(0), '') AS Specs_OPR,
OPERATION.WORKORDER_BASE_ID,
OPERATION.WORKORDER_LOT_ID,
OPERATION.WORKORDER_SPLIT_ID,
OPERATION.WORKORDER_SUB_ID,
OPERATION.LOAD_SIZE_QTY,
OPERATION.CALC_START_QTY,
OPERATION.COMPLETED_QTY,
(CEILING(OPERATION.CALC_START_QTY/OPERATION.LOAD_SIZE_QTY)) AS NUM_O_LOADS,
((OPERATION.CALC_START_QTY - OPERATION.COMPLETED_QTY)/OPERATION.LOAD_SIZE_QTY) AS LOADS_REMAINING,
-- SubQuery
(
SELECT DISTINCT
descriptions = STUFF(
(
SELECT ', '+CHAR(13)+PART.DESCRIPTION
FROM dbo.PART
JOIN REQUIREMENT ON PART.ID = REQUIREMENT.PART_ID
WHERE REQUIREMENT.WORKORDER_BASE_ID = '026877'
AND REQUIREMENT.OPERATION_SEQ_NO = '30'
FOR XML PATH(''), TYPE
).value('.[1]', 'nvarchar(max)'), 1, 2, '')
FROM(REQUIREMENT R
JOIN PART P ON R.PART_ID = P.ID)
) AS PART_DESCRIPTION
-- End of SubQuery
FROM OPERATION
INNER JOIN WORK_ORDER ON OPERATION.WORKORDER_TYPE = WORK_ORDER.TYPE
AND OPERATION.WORKORDER_BASE_ID = WORK_ORDER.BASE_ID
AND OPERATION.WORKORDER_LOT_ID = WORK_ORDER.LOT_ID
AND OPERATION.WORKORDER_SPLIT_ID = WORK_ORDER.SPLIT_ID
AND OPERATION.WORKORDER_SUB_ID = WORK_ORDER.SUB_ID
INNER JOIN OPERATION_BINARY ON OPERATION.WORKORDER_TYPE = OPERATION_BINARY.WORKORDER_TYPE
AND OPERATION.WORKORDER_BASE_ID = OPERATION_BINARY.WORKORDER_BASE_ID
AND OPERATION.WORKORDER_LOT_ID = OPERATION_BINARY.WORKORDER_LOT_ID
AND OPERATION.WORKORDER_SPLIT_ID = OPERATION_BINARY.WORKORDER_SPLIT_ID
AND OPERATION.WORKORDER_SUB_ID = OPERATION_BINARY.WORKORDER_SUB_ID
AND OPERATION.SEQUENCE_NO = OPERATION_BINARY.SEQUENCE_NO
JOIN REQUIREMENT ON REQUIREMENT.WORKORDER_BASE_ID = OPERATION.WORKORDER_BASE_ID
WHERE(REPLACE(CONVERT(VARCHAR(8000), CONVERT(BINARY(8000), OPERATION_BINARY.BITS)), CHAR(0), '') NOT LIKE '%Gupta%')
AND OPERATION.WORKORDER_BASE_ID = '026877'
AND WORK_ORDER.BASE_ID = '026877';
これは私が今持っているものであるが、いくつかの理由で私の場合は私の3行の結果に4行目を作成しました：
SELECT DISTINCT
WORK_ORDER.PART_ID,
OPERATION.SEQUENCE_NO,
OPERATION.RESOURCE_ID,
OPERATION.SETUP_HRS,
OPERATION.RUN_HRS,
OPERATION.OPERATION_TYPE,
OPERATION.RUN AS PCS_HR,
REPLACE(CONVERT(VARCHAR(150), CONVERT(BINARY(150), OPERATION_BINARY.BITS)), CHAR(0), '') AS Specs_OPR,
OPERATION.WORKORDER_BASE_ID,
OPERATION.WORKORDER_LOT_ID,
OPERATION.WORKORDER_SPLIT_ID,
OPERATION.WORKORDER_SUB_ID,
OPERATION.LOAD_SIZE_QTY,
OPERATION.CALC_START_QTY,
OPERATION.COMPLETED_QTY,
(CEILING(OPERATION.CALC_START_QTY/OPERATION.LOAD_SIZE_QTY)) AS NUM_O_LOADS,
((OPERATION.CALC_START_QTY - OPERATION.COMPLETED_QTY)/OPERATION.LOAD_SIZE_QTY) AS LOADS_REMAINING,
-- SubQuery Inside Case

ボトムラインは、いいえ、あなたがすることはできませんが、あなたは質問にSQL文を貼り付ける場合、私たちはあなたが後にあるものを達成する別のアプローチを提案することができます確信しています。 –
申し訳ありませんが、コピー貼り付けが非常に面倒で扱いにくい場合があるので、特に私のクエリの長さでは、私はimgurリンクを投稿した方がクリーンであると思っていました。 – Azuraith
