sql-server - MIN/MAX 値を持つ行の他のフィールド値を取得する

Question

これが私のデータのサンプルであり、私が見たいものです：

JOB    OPSEQ    OPCOMPLETE   OPCODE

100     1        yes          pull  
100     2        yes          weld  
100     3        no           grind    
100     4        no           machine  
100     5        no           asmbl

したがって、opcomplete=no の場合の min(opseq) と opcomplete=yes の場合の max(opseq)、および min と max opseq のオペコードを選択したいと考えています。この例では、次のようになります:
min(opseq):3最小操作
のオペコード: 研磨
max(opseq): 2 最大操作のオペコード: 溶接

私がこれを探している理由は、完全ではない最小の opseq のオペコードを取得するためです。
最小および最大 opseqs がうまく機能するようになりました。これは私が持っていたものです：

(SELECT   company, jobnum, MAX(oprseq) AS maxclosed, opcomplete
 FROM     joboper AS joboper_2
 WHERE    (company = 'lot') AND (opcomplete = '1')
 GROUP BY company, jobnum, opcomplete) AS t_joboper1 ON joboper.company = t_joboper1.company AND joboper.jobnum = t_joboper1.jobnum INNER JOIN
(SELECT   company, jobnum, MIN(oprseq) AS minopen, opcomplete
 FROM     joboper AS joboper_1
 WHERE    (company = 'lot') AND (opcomplete = '0')
 GROUP BY company, jobnum, opcomplete) AS t_joboper2 ON joboper.company = t_joboper2.company AND joboper.jobnum = t_joboper2.jobnum

そのため、オペコードを追加しようとしても機能せず、あらゆる種類の重複値を取得し始めました。これは私が書いたものです：

(SELECT   company, jobnum, MAX(oprseq) AS maxclosed, opcomplete, opcode as maxopcode
 FROM     joboper AS joboper_2
 WHERE    (company = 'lot') AND (opcomplete = '1')
 GROUP BY company, jobnum, opcomplete, opcode) AS t_joboper1 ON joboper.company = t_joboper1.company AND joboper.jobnum = t_joboper1.jobnum INNER JOIN
(SELECT   company, jobnum, MIN(oprseq) AS minopen, opcomplete, opcode as minopcode
 FROM     joboper AS joboper_1
 WHERE    (company = 'lot') AND (opcomplete = '0')
 GROUP BY company, jobnum, opcomplete, opcode) AS t_joboper2 ON joboper.company = t_joboper2.company AND joboper.jobnum = t_joboper2.jobnum

現時点でのコード全体を次に示します (オペコードはすべての重複値を取り込みます:

SELECT     jobhead.company, jobhead.jobnum, jobhead.partnum, 
           jobhead.partdescription, jobhead.startdate,

私がここでやろうとしていることは、これがすべて意味をなすことを願っています。完全に明らかでない場合は、ここで質問するのはこれが初めてです。事前に、すべての助けに感謝します!!!

助けてくれてありがとう！両方の提案を試しましたが、どちらも希望どおりの結果を得ることができませんでした。しかし、それぞれの答えは、最終的に必要なものを手に入れるのに必要なものにたどり着くのに役立ちました。これは私の最初の質問なので、どの回答を解決策としてマークするまで何をすべきかわかりませんか? 私が言ったように、両方の答えが私を大いに助けてくれました. これにさらに取り組んだ後、私は自分の質問を明確にするために一生懸命努力しましたが、戻ってみると、どうすれば物事をもっとうまく表現できたのかがわかります. 繰り返しますが、私はすべての助けに非常に感謝しており、将来より良い質問をすることを楽しみにしています.

1 つのアプローチを次に示します。

select JOB,
       min(case when OPCOMPLETE = 'no' then OPSEQ end) as MIN_NO_OPSEQ,
       min(case when OPCOMPLETE = 'no' then OPCODE end) as MIN_NO_OPCODE,
       min(case when OPCOMPLETE = 'yes' then OPSEQ end) as MAX_YES_OPSEQ,
       min(case when OPCOMPLETE = 'yes' then OPCODE end) as MAX_YES_OPCODE
  from ( select JOB,
                OPSEQ,
                OPCOMPLETE,
                OPCODE,
                rank() over (partition by JOB, OPCOMPLETE order by OPSEQ asc) as R_NO,
                rank() over (partition by JOB, OPCOMPLETE order by OPSEQ desc) as R_YES
           from TABLE_NAME
       )
 where OPCOMPLETE = 'no' and R_NO = 1    -- row with min(OPSEQ) where OPCOMPLETE = 'no'
    or OPCOMPLETE = 'yes' and R_YES = 1  -- row with max(OPSEQ) where OPCOMPLETE = 'yes'
 group
    by JOB
;

ノート：

未検証。
2 行目から 5行目では、1 つの行だけがすべての必要な基準を満たすため、それぞれminを変更しても効果はありません。max(minまたはmax) が必要なのは、group bynull 以外の値を選択して 2 つの行を 1 つに結合するためです。
の詳細については、 MSDN のドキュメントをrank()参照してください。

OPSEQ が一意の値である限り、これはあなたが作っているよりもずっと簡単だと思います:

select
    opseq, opcode
from
    joboper
where
    opseq in (select min(opseq) from joboper where opcomplete = 'no')
    or
    opseq in (select max(opseq) from joboper where opcomplete = 'yes')

SQL Server 2005 以降を使用していると仮定すると、次CROSS APPLYのようにを使用することも検討できます。

SELECT
  j.JOB,
  y.OPSEQ  AS LastCompleteOPSEQ,
  y.OPCODE AS LastCompleteOPCODE,
  n.OPSEQ  AS FirstIncompleteOPSEQ,
  n.OPCODE AS FirstIncompleteOPCODE
FROM (SELECT DISTINCT JOB FROM joboper) j
CROSS APPLY (
  SELECT TOP 1 OPSEQ, OPCODE
  FROM joboper
  WHERE JOB = j.JOB AND OPCOMPLETE = 'yes'
  ORDER BY OPSEQ DESC
) y
CROSS APPLY (
  SELECT TOP 1 OPSEQ, OPCODE
  FROM joboper
  WHERE JOB = j.JOB AND OPCOMPLETE = 'no'
  ORDER BY OPSEQ ASC
) n
;
