语法问题与BEGIN ... SET ... END

Question

我写了使用日期维度表来计算给定开始日期和频率的日期的下一个出现以下存储过程。

我越来越似乎每当我有一个IF BEGIN SET如果设置END顺序发生一些奇怪的语法错误。

为了帮助调试，我已经回到和增加不必要的BEGIN和周围的一行IF语句END语句。

我缺少某种类型的BEGIN - END或IF - ELSE这里匹配规则？ （我标志着解析器抱怨与意见的线条。）

你缺少一个右)：

BEGIN 
    SET @Date = ((
    SELECT TOP(1) [Date] 
    FROM dbo.dim_Date 
    WHERE (([DATE] > @Date) AND IsBusinessDay = 1) 
    ORDER BY [Date])) -- Paren added here... 
END --Parser ERROR: Incorrect syntax near the keyword 'END'.
