Sql server 如何在sql中向表中添加图片（带参数）

我的代码如下：

CREATE PROCEDURE USP_AddUser
    @Name Nvarchar(50), 
    @LastName Nvarchar(50), 
    @PictureAddress nvarchar(50)
As
Begin
    Insert tbl_Users(Name, LastName, Picture) 
       Select 
           @Name, @LastName, BulkColumn 
       From 
           OpenRowSet(Bulk 'c:\s.jpg', single_blob) as img 
End

这段代码很有效，但当我将图像地址更改为@PictureAddress时，如下所示：

CREATE PROCEDURE USP_AddUser
    @Name Nvarchar(50), 
    @LastName Nvarchar(50), 
    @PictureAdress nvarchar(50)
As
Begin
    Insert tbl_Users(Name, LastName, Picture) 
        Select 
           @Name, @LastName, BulkColumn 
        From 
           OpenRowSet(Bulk @PictureAdress, single_blob) as img 
End

这行不通。错误是

“@PictureAddress”附近的语法不正确。字符串或文本除外

我能做什么？感谢您的回复

OPENROWSET语句中不允许使用变量。您必须使用动态sql：

CREATE PROCEDURE USP_AddUser
    @Name Nvarchar(50), 
    @LastName Nvarchar(50), 
    @PictureAdress nvarchar(50)
As
Begin

DECLARE @sql varchar(max);

SET @sql = '
        Select 
           '+@Name+', '+@LastName+', BulkColumn 
        From 
           OpenRowSet(Bulk '+@PictureAdress+', single_blob) as img 
';

 Insert tbl_Users(Name, LastName, Picture) 
 EXEC (@sql);

结束
