我正在尝试从BINARY列中查找特定的数据行。

列中的示例数据BINARY(2000)：

该数据中有 1 个结果2201。（尝试搜索 2201 的数据，您将得到 1。）

现在我正在尝试使用这个查询：（它应该给我 512 行结果）

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

但没有运气得到结果。

注意：2201 实际上是 290。我试图在字节序的数据中查找十进制值 290，即十六进制的 2201。

更新：

试过这个查询（搜索：​​15584）

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

现在它返回几乎所有行。甚至手动检查了 E03C 的行，但没有找到，但是在运行查询时它被返回。很奇怪。想法？

LIKE运算符仅适用于字符数据类型。尝试对字符串进行CAST ，如下所示：

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

- 或者 - 

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

此外，如果您想查看数据的子集（例如文件头），您可以执行以下操作：

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;

编辑

关于您更新的问题，这是否会给您带来您期望的结果：

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

您不必将字符数据转换/转换为二进制。
