我正在尝试在我的存储过程中执行此操作:
declare @CategoryId int -- stuff IF EXISTS (select A_categoryId from dbo.categories where B_categoryId = @b_categoryId and C_cactegoryId = @c_categoryId ) -- it doesn't like the following line: @CategoryId = select A_categoryId from dbo.categories where B_categoryId = @b_categoryId and C_cactegoryId = @c_categoryId
但它不喜欢它的结构方式。任何想法?

这就是你要找的东西:
set @CategoryId = (select A_categoryId from dbo.categories
where B_categoryId = @b_categoryId
and C_cactegoryId = @c_categoryId)
答案 1 :(得分:2)
SELECT @CategoryId = A_categoryId from dbo.categories...
话虽如此,请不要发布有关如何在SO上分配变量的问题。这实际上远低于网站的范围,可以通过查看SQL Server的任何文档来解决。
