I’ve created a sproc to delete multiple records by accepting a comma-delimited list of ID’s as varchar, and using IN to attempt the deletion – doesn’t work:

ALTER PROCEDURE [dbo].[sp_DeleteItemsFromItemCategories]
 @UserID bigint,
 @ItemsList varchar(8000)
AS
BEGIN
 -- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
 SET NOCOUNT ON;
 DELETE 
 FROM tbl_ItemFoldersLnk
 WHERE LineItemID IN (SELECT LineItemID FROM tbl_ItemFoldersLnk WHERE LineItemID IN (@ItemsList))
END

Initially I had … IN (@ItemList) but still does not work. The error is “Error converting data type varchar to bigint.”

I do have other SPROCS that iterate through comma delimited lists which I could use to delete, but then I’m running a delete function for each row.

Suggestions?

Thanks.

    Arrays and lists in SQL Server.

    You need to change the CSV into a table (as per article) and join to filter.

    You are literally comparing the ID columns with the string “1, 45, 67” which is not an integer…
