我正在运行SQL代码，并且在传递某些信息时收到错误。

当我取消注释--where [CUSTID] like 'sci'并注释掉品牌时，查询会运行并且能够看到结果。但是，当我在品牌推广的地方运行时，我得到一个错误：

Msg 8116，Level 16，State 1，Line 1
对于类似函数的参数2，参数数据类型varchar无效。

另外一件事是当我通过BRANDING desc取消注释它时，它给了我另一个错误。

该错误是

消息306，级别16，状态2，行3文本，ntext和图像数据除非使用IS NULL或LIKE，否则无法比较或排序类型操作

我需要做什么才能让命令真正起作用？

Answer 1

如果BRANDING类型为IMAGE，则会出现此错误消息，这是无法比拟的（从字面上看，它无法以任何方式进行比较，甚至无法与其他{{1}进行比较}）。为了克服此类型的限制，SQL Server 2005引入了IMAGE类型，它具有相同的目的，但没有VARBINARY(MAX)所需的特殊案例处理（同样，IMAGE被引入来取代(N)VARCHAR(MAX)）。 (N)TEXT不应该用于新工作; IMAGE在所有方面都优越。如果现有的VARBINARY(MAX)列可以更改为IMAGE，请执行此操作。

如果无法做到，VARBINARY(MAX)仍然可以即时转换。在上面的查询中：

IMAGE

此处select * from OBX.BTOCUST where CONVERT(VARBINARY(MAX), BRANDING) <> 0x476737.....00003B是0x476737....字面值。要将十六进制字符串转换为二进制数，请使用BINARY（带前导“0x”）或CONVERT(VARBINARY(MAX), @string, 1)（不带前导“0x”）。

Answer 2

将图像或文本或ntext列数据类型转换为varbinary（max），varchar（max）或nvarchar（max）。

不推荐使用image，text和ntext数据类型，将在SQL Server的未来版本中删除它们。与他们合作非常困难和尴尬。 varchar（max）和nvarchar（max）具有几乎无限的字符串大小的所有好处，并且没有text或ntext的缺点。它们还可以处理您期望的所有常规字符串函数。

Answer 3

这是我完成的一种快速而肮脏的方法，但是请记住，在没有全文本的情况下，您对服务器的要求是什么。它会将数据类型不匹配忽略为消息输出中的低级错误。您可以在消息输出运行时对其进行初步检查。

Declare @SearchString nvarchar(50) = 'SEARCH STRING HERE'
Declare @TableList Table (TableName nvarchar(128))
Declare @Table nvarchar(128)
Declare @ColumnList Table (ColumnName nvarchar(128))
Declare @Column nvarchar(128)
Declare @Results Table (TableName nvarchar(128), ColumnName nvarchar(128), String nvarchar(max))
Declare @cmd nvarchar(max)

Insert Into @TableList
Select TABLE_NAME From INFORMATION_SCHEMA.Tables Where Table_Type = 'BASE TABLE'

While Exists (Select 1 From @TableList)
Begin

Set @Table = (Select Top 1 TableName From @TableList)
Print 'Searching '+@Table+'...'

Insert Into @ColumnList
Select Column_Name From INFORMATION_SCHEMA.Columns Where Table_Name = @Table

While Exists (Select 1 From @ColumnList)
Begin

    Set @Column = (Select Top 1 ColumnName From @ColumnList)
    Print 'Searching ' +@Table + '.' + @Column+'...'

    Set @cmd = 'Select '''+@Table+''', '''+@Column+''', '+@Column+' From '+@Table+' Where '+@Column+' Like ''%'+@SearchString+'%'''     

    --Select @cmd

    Insert Into @Results
    Exec (@cmd)

    Delete From @ColumnList Where ColumnName = @Column

End

Delete From @TableList Where TableName = @Table

End

Select * From @Results

参数类型varchar无效
