执行存储过程的问题？

我有尝试执行存储过程的问题..执行存储过程的问题？

USE [OPPY_DWUSD] 
GO 

DECLARE @return_value int 

EXEC @return_value = [dbo].[truncate_non_empty_table] 
     @TableToTruncate = '[fact].[SALES]' 

SELECT 'Return Value' = @return_value 

GO

在上面的例子TSQL，我不断收到这个错误..

消息105，15级，状态1，第1行
字符串'SALES]'后面未加上引号。
Msg 102，Level 15，State 1，Line 1
'SALES]'附近的语法错误。

不知道我在做什么错？我也尝试过N'fact.SALES'，但没有奏效。

我试图传入TableToTruncate的表称为“fact.SALES”。

作为模式的“事实”。

有关如何解决此问题的任何想法？

谢谢。

我看到你有一些调试代码打印您的动态SQL语句;你用它来一个一个地生成和测试它们吗？有什么东西在你的代码，不喜欢表名的格式，但它是一个大量的代码为别人挑选过了，既然你已经到位的调试代码好像你应该能够很容易地缩小这个下来。 – Pondlife

需要一个逗号

USE [OPPY_DWUSD] 
GO 

DECLARE @return_value int 

EXEC @return_value = [dbo].[truncate_non_empty_table], -- <=== comma here 
     @TableToTruncate = '[fact].[SALES]' 

SELECT 'Return Value' = @return_value 

GO

也，不知道，你可能需要指定@return_value为Out参数

EXEC @return_value = [dbo].[truncate_non_empty_table] Out, -- <=== comma here and Out 
     @TableToTruncate = '[fact].[SALES]'

这并不会工作。消息102，级别15，状态1，4号线附近有语法错误“”。 – exxoid

T他的错误似乎来自Stored Proc内部。我假设在proc中发生了一些动态SQL，这些动态SQL与您使用的格式无法正确结合。
