sql-server - SQL Server：类似语法和添加运算符错误

Question

我正在使用这种语法，如果它没有出错，它应该可以正常工作。

SELECT
   e.user_key,
   e.char_key,
   CONVERT(VARCHAR,substring(e.char_data, 9, 16)) AS name,
   p.CHAR_DATA
FROM 
   CHAR_DATA0 AS e
INNER JOIN  
   CHAR_DATA1 AS p ON e.CHAR_KEY = p.CHAR_KEY
WHERE 
   p.CHAR_DATA LIKE '%'+CAST(cast(reverse(CONVERT(BINARY, 9998)) as BINARY(2)) AS BINARY(2))+'%'
ORDER BY 
   char_key

我需要帮助。如何更改此代码以使其正常工作？

CHAR_DATA列是类型BINARY(2000)

我有这样的数据：（使用选择获得）

如果其中包含我要查找的条目，我需要在这些行中的某个位置进行搜索。

我要查找的始终是 2 个字节。所以我在上面的语法中寻找 0x0E27 。

这是一种有效的语法，但不是我想要做的：

SELECT 
   CONVERT(INT,cast(reverse(substring(char_data, 37, 2)) as BINARY(2))) AS helm 
FROM CHAR_DATA0 
WHERE CHAR_KEY = 5

另一个是如果我使用 nvarchar(MAX) 它给出的结果甚至不包含我要查找的数据。

Answer 1

where Convert(varChar(4000), CHAR_DATA,2 ) like '%' + Convert(varChar(4), CONVERT(BINARY(2), 9998),2 )+'%'

Answer 2

我尝试只选择 like 子句，主要是因为我不需要您的架构（表）这样做，并且已经发现了一个错误（我认为）：

SELECT '%' + CAST( CAST(REVERSE(CONVERT(BINARY, 9998)) as BINARY(2)) AS BINARY(2) ) + '%'

产生：

Msg 402, Level 16, State 1, Line 1
The data types varchar and binary are incompatible in the add operator.

...其中（将整体结果类型更改为 varchar）：

SELECT '%' + CAST( CAST(REVERSE(CONVERT(BINARY, 9998)) as BINARY(2)) AS VARCHAR(2) ) + '%'

产生（我们需要一些运气在这里的编码）：

%'%    -- that is: percent, apostrophe, beam (the musical note), percent

也许这就是整个问题（尽管我对此表示怀疑）？试试看，让我们知道你的进展。我对此表示怀疑，因为我猜如果这是整个问题，那么您会从错误消息中自己解决（我认为您会从 SQL-Server 获得）。

干杯。基思。
