このデータには、2201どこかの結果が 1 つあります。(2201 のデータを検索してみると、1 が得られます。)

今、私はこのクエリを使用しようとしています:(512行の結果が得られるはずです)

SELECT * 
FROM table
WHERE binaryfield LIKE '%2201%'
ORDER BY key

しかし、結果を得るには運がありません。

注: 2201 は実際には 290 です。エンディアンのデータで 16 進数の 2201 である 10 進数値 290 を探しています。

アップデート：

このクエリを試しました (検索: 15584)

SELECT *
FROM CHAR_DATA1
WHERE CHAR_DATA LIKE '%'+CAST(0xE03C AS nvarchar(MAX))+'%'
ORDER BY CHAR_KEY;

これで、ほぼすべての行が返されます。E03C の行を手動でチェックしても何も見つかりませんでしたが、クエリを実行すると返されます。非常に奇妙な。アイデア？

LIKE演算子は、文字データ型でのみ機能します。次のように、文字列にCASTを実行してみてください。

SELECT * 
  FROM table
 WHERE CAST(binaryfield AS nvarchar(MAX)) LIKE '%290%'
 ORDER BY key;

- また - 

SELECT * 
  FROM table
 WHERE CAST(binaryfield AS nvarchar(MAX)) LIKE '%'+CAST(0x2201 AS nvarchar(MAX))+'%'
 ORDER BY key;

また、データのサブセット (ファイル ヘッダーなど) を見たい場合は、次のようにすることができます。

SELECT * 
  FROM table
 WHERE CAST(LEFT(binaryfield, 8) AS nvarchar(MAX)) -- Only compares the first 8 bytes
         LIKE '%'+CAST(0x2201 AS nvarchar(MAX))+'%'
    OR CAST(SUBSTRING(binaryfield, 34, 4) AS nvarchar(MAX)) -- Compares bytes 34-38
         LIKE '%'+CAST(0x2201 AS nvarchar(MAX))+'%'
 ORDER BY key;

更新された質問に関して、これはあなたが期待している結果をもたらしますか:

 SELECT *
   FROM CHAR_DATA1
  WHERE CHAR_DATA COLLATE SQL_Latin1_General_CP1_CI_AS
          LIKE '%'+CAST(0xE03C AS nvarchar(MAX))+'%'
 ORDER BY CHAR_KEY;

文字データをバイナリにキャスト/変換する必要はありません。
