如何将int值列表从后面的代码传递给SP？

Question

I have a List of int in that i am getting some value now I want to pass all the value to my store procedure one by one or comma separated,

Code Behind:

Cmd.Parameters.AddWithValue("@ImageId", IDList); //IDList is list of int which need to pass in my SP

in SP

@ImageId int //declaration

IF Not Exists(SELECT ImgIns.Id FROM ImgIns WHERE ImgIns.ImageId =@ImageId)

Answer 1

Passing them in a comma separated string and split it in t-sql is the best option I found so far.

Split function equivalent in T-SQL? will help for the split operation.

In Code Behind :

var IDList = String.Join(",", new List<int> {1,2,3});
Cmd.Parameters.AddWithValue("@ImageIds", IDList);

Answer 2

Create a sql function to split the list of comma separated int http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=50648 insert this list into some table varibale and then you can wrtie your SP like

DECLARE @ImageIDs TABLE (ImageID INT)

INSERT INTO @ImageIDs select * from dbo.fn_Split(@ImageID)

IF EXISTS (SELECT 1 FROM ImageINstance I INNER JOIN @ImageIDs Img ON I.ImageID = Img.ImageID)

For now I am passing the value one by one with the help of for loop and its working fine for me..

 for (int i = 0; i < IDList.Count; i++)
 {
    Cmd.Parameters.Clear();
    Cmd.Parameters.AddWithValue("@ImageId", IDList[i]);
 }
