二進制列SELECT like

Question

我試圖從BINARY列中找到特定的數據行。在BINARY(2000)柱

實施例的數據：

該數據具有的2201在某處1分的結果。 （爭取2201搜索數據，您將獲得1）

現在我想要使用此查詢：（它應該給我512行的結果）

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

但在沒有得到運氣結果。

說明：2201實際上是290.我試圖尋找十進制值290，它是以十六進制表示的數據在endian中是2201。

更新：

嘗試這種查詢（搜索：​​15584）

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

現在它返回幾乎所有行。即使手動檢查了E03C的行但沒有找到，但運行查詢時會返回。很奇怪。想法？

Answer 1

LIKE運算符僅適用於字符數據類型。試着做一個CAST爲一個字符串，像這樣：

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

- 或 -

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

另外，如果你想看看數據的一個子集（例如文件頭），你可以做這樣的事情：

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;

編輯

關於你更新的問題，這是否給你的是你期待的結果：

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

你不應該投/字符數據轉換爲二進制。
