我需要在函数中使用动态SQL,以便我可以执行SELECT * FROM searchAllFields('Pregnant')
之类的操作。我知道在函数中不可能使用动态SQL,但我发现这个人找到了一个解决方法Getting an error when executing a dynamic sql within a function (SQL Server)?
但是当我尝试在mycode上应用他的工作时,我得到A RETURN statement with a return value cannot be used in this context.
看起来我正在做同样的事情。为什么我在代码中出现错误?
ALTER proc [dbo].[searchTerm](@search nvarchar(max))
as
begin
declare @value nvarchar(500),
@SQLString nvarchar(4000),
@stmt nvarchar(max)
select @stmt = isnull(@stmt + ' or ', '') + quotename(name) + ' like @search'
from sys.columns as c
where c.[object_id] = object_id('dbo.table')
select @stmt = 'select @value = id from table where ' + @stmt
exec sp_executesql
@stmt = @stmt,
@params = N'@search nvarchar(max)',
@search = @search,
@value = @value output
return @value
end
答案 0 :(得分:0)
看起来这不起作用,因为你的函数返回inline table-valued function。
对于此语法,函数定义后跟AS RETURN ( SELECT ... )
而不是AS BEGIN... RETURN ... END
