例 CatTerm_id = 613

SELECT
     CatalogTerm_Id
    ,CatalogResolution_Id
    ,Catalogresolution.name
    ,CatalogRegulation.Threshold
    ,OptionItem.name
    ,ApprovalType =
          CASE
               WHEN OptionItem.name LIKE 'Corporate' THEN 1
               WHEN OptionItem.name LIKE 'GEO' THEN 2
               WHEN OptionItem.name LIKE 'Country/Area' THEN 3 ELSE 4
          END
FROM CatalogResolution, CatalogRegulation, OptionItem
WHERE CatalogTerm_Id = 613
     AND CatalogResolution.ID = CatalogResolution_id
     AND OptionItem.ID = CatalogRegulation.Level_Id
     AND type_id IN (645)
     AND CatalogResolution.IsDeleted = 0
     AND CatalogRegulation.IsDeleted = 0
ORDER BY CatalogTerm_Id

出力:

613 1051 

Country/Area    3

613 1053 

Geo 2

613 1054 

     Country/Area   3

出力: 国/地域。

しかし、ディスプレイには GEO が表示され、CatTerm_id を指定せずにリスト全体に拡張できます。

SELECT TOP 1
     CatalogTerm_Id
    ,CatalogResolution_Id
    ,Catalogresolution.name
    ,CatalogRegulation.Threshold
    ,OptionItem.name
    ,ApprovalType =
          CASE
               WHEN OptionItem.name LIKE 'Corporate' THEN 1
               WHEN OptionItem.name LIKE 'GEO' THEN 1
               WHEN OptionItem.name LIKE 'Country/Area' THEN 1 ELSE 4
          END
FROM CatalogResolution, CatalogRegulation, OptionItem
WHERE CatalogTerm_Id = 613
     AND CatalogResolution.ID = CatalogResolution_id
     AND OptionItem.ID = CatalogRegulation.Level_Id
     AND type_id IN (645)
     AND CatalogResolution.IsDeleted = 0
     AND CatalogRegulation.IsDeleted = 0
ORDER BY CatalogTerm_Id

613 1051
国/地域 1

これは私が欲しいものではない 私が欲しいのは「GEO」

次のように order by 句を追加してから、結果から上位 1 つを選択してみてください

ケースバイケース
「企業」の場合 THEN 1
「GEO」のとき THEN 1
when '国/地域' THEN 1
終わり
