Question

我在执行查询时遇到上述错误，这是一个存储过程命令行执行

exec sp_Bind_Division_Store_Camera_On_Filter_In_Liveview 
     null, null, null, null

存储过程如下

ALTER PROCEDURE [dbo].[sp_Bind_Division_Store_Camera_On_Filter_In_Liveview]
    @division varchar(45),
    @store varchar(45),
    @camera varchar(68),
    @group varchar(100)

现在错误显示我在第34行错误的语法附近＆＃39;。＆＃39;，但我发现没有任何问题，因为我运行此查询表单命令提示符非常好地应用于存储过程，它会引起错误。请帮我解决这个问题。

您可以轻松打印变量@BaseQuery以检查生成的查询。

变量@BaseQuery中的查询看起来像这样

select 
                                            distinct tblcameradetails.name as CameraName,

您可以看到WHERE和ORDER BY子句之前缺少空格

您需要在WHERE和ORDER BY变量的开头添加一个空格，如下所示

@WhereClause nvarchar(max) = N' where 
 @OrderByClause nvarchar(100) = ' order by CameraName';

Answer 2

尝试将一些PRINT放在查询的中间。

例如PRINT @BaseQuery之后的SET @BaseQuery = @BaseQuery + @WhereClause + @OrderByClause;

因为某些变量可能需要空格（例如N' where...1=1'而不是N'where...1=1'）

消息102，级别15，状态1，行34错误的语法附近＆＃39;。＆＃39;
