Sql server 存储过程中的SQL函数不工作

在存储过程中，我尝试使用函数

代码如下：

SELECT TOP 4 
    refFeatured,
    [Type],
    [Order],
    fn_cms_featured_image(refFeatured,[Type],@refLanguage) AS FeaturedImage,
    fn_cms_featured_name(refFeatured,[Type],@refLanguage) AS Name 
FROM
    FEATURED
ORDER BY 
    [Order] ASC 

我写了函数，但没有工作

“fn\u cms\u特色图像”不是可识别的函数名

SELECT TOP 4 refFeatured, 
       [Type],
       [Order], 
       [dbo].fn_cms_featured_image(refFeatured,[Type],@refLanguage) AS FeaturedImage, 
       [dbo].fn_cms_featured_name(refFeatured,[Type],@refLanguage) AS Name 
FROM  FEATURED 
ORDER BY [Order] ASC

出现上述错误。我在哪里犯错误

函数是标量值函数

ALTER FUNCTION [dbo].[fn_cms_featured_image] ( @iNumber int,@type nvarchar(20),@lang int )
RETURNS nvarchar(50)
AS
BEGIN
    DECLARE @image  nvarchar(100)

    IF @type ='Category'
        SET @image = (SELECT TOP 1 c.Icon FROM CATEGORY c WHERE c.Id=@iNumber)
    ELSE
        SET @image = (SELECT TOP 1 pl.DefaultImage FROM  PRODUCT_IMAGE_LOCALIZED pl WHERE  pl.refLanguage=@lang AND pl.refProduct=@iNumber)

    RETURN (@image)
END

调用用户函数的名称前应加上架构名称。

尝试写入

选择dbo.fn\u cms\u特色图像（…

在函数名前面添加架构名

[dbo]。

SELECT TOP 4 refFeatured, 
       [Type],
       [Order], 
       [dbo].fn_cms_featured_image(refFeatured,[Type],@refLanguage) AS FeaturedImage, 
       [dbo].fn_cms_featured_name(refFeatured,[Type],@refLanguage) AS Name 
FROM  FEATURED 
ORDER BY [Order] ASC

看看这篇文章：

试试看

Select item from fn_cms_featured_image(refFeatured,[Type],@refLanguage) AS FeaturedImage

而不是直接打电话

fn_cms_featured_image(refFeatured,[Type],@refLanguage) AS FeaturedImage

我还建议不要在代码中使用标量函数，它们是性能瓶颈，请使用内联表值函数重写它们。您的问题是否通过任何一个答案得到解决，或者问题仍然存在？
