无法在数据库中使用逗号存储字符串

Question

我正在使用以下行来在数据库中存储字符串，但目前无法将其存储为单个字符串。每次在字符串中遇到逗号时，它都会在数据库表中创建一个新行。

cmd.Parameters.AddWithValue("@ImageURL", String.Join(",", img.ToArray())); 

这是怎么回事？

这是多么我已经定义的表：

@ImageURL VARCHAR(max) 

AS 
BEGIN 
    SET NOCOUNT ON added to prevent extra result sets from 
    interfering with SELECT statements. 
    SET NOCOUNT ON; 


    Insert statements for procedure here 
    insert into 
    DECLARE @String VARCHAR(100) 

    SET @String =''    

    IF(LEN(@Images)>0)   
    BEGIN   
     DELETE FROM Business_images WHERE BusinessId=@BusinessId   
    END   

    WHILE LEN(@ImageURL) > 0    
    BEGIN   
    SET @String = LEFT(@ImageURL, ISNULL(NULLIF(CHARINDEX(',', @ImageURL) - 1, -1), LEN(@ImageURL)))    
    SET @ImageURL = SUBSTRING(@ImageURL, ISNULL(NULLIF(CHARINDEX(',', @ImageURL), 0), LEN(@ImageURL)) + 1, LEN(@ImageURL)) 

    insert into Images(ImageURL) values (@String) 
    END 
END 

Answer 1

string specialString = "this is silly, string,,not so special''special"; 
using (SqlConnection conn = new SqlConnection(connectionString)) 
{ 
    using (SqlCommand command = new SqlCommand("Insert into t1 (col1) VALUES (@parame)")) 
    { 
     command.Connection = conn; 
     command.Parameters.AddWithValue("@parame",specialString); 
     command.ExecuteNonQuery(); 
    } 
} 

FYI：我是能够插入到SQL Server。在我的情况col1的类型是nvarchar
